| 8 | Introduction | ||
| 9 | ------------ | ||
| 10 | |||
| 11 | This file describes how to use the DM9000 platform-device based network driver | ||
| 12 | that is contained in the files drivers/net/dm9000.c and drivers/net/dm9000.h. | ||
| 13 | |||
| 14 | The driver supports three DM9000 variants, the DM9000E which is the first chip | ||
| 15 | supported as well as the newer DM9000A and DM9000B devices. It is currently | ||
| 16 | maintained and tested by Ben Dooks, who should be CC: to any patches for this | ||
| 17 | driver. | ||
| 18 | |||
| 19 | |||
| 20 | Defining the platform device | ||
| 21 | ---------------------------- | ||
| 22 | |||
| 23 | The minimum set of resources attached to the platform device are as follows: | ||
| 24 | |||
| 25 | 1) The physical address of the address register | ||
| 26 | 2) The physical address of the data register | ||
| 27 | 3) The IRQ line the device's interrupt pin is connected to. | ||
| 28 | |||
| 29 | These resources should be specified in that order, as the ordering of the | ||
| 30 | two address regions is important (the driver expects these to be address | ||
| 31 | and then data). | ||
| 32 | |||
| 33 | An example from arch/arm/mach-s3c2410/mach-bast.c is: | ||
| 34 | |||
| 35 | static struct resource bast_dm9k_resource[] = { | ||
| 36 | [0] = { | ||
| 37 | .start = S3C2410_CS5 + BAST_PA_DM9000, | ||
| 38 | .end = S3C2410_CS5 + BAST_PA_DM9000 + 3, | ||
| 39 | .flags = IORESOURCE_MEM, | ||
| 40 | }, | ||
| 41 | [1] = { | ||
| 42 | .start = S3C2410_CS5 + BAST_PA_DM9000 + 0x40, | ||
| 43 | .end = S3C2410_CS5 + BAST_PA_DM9000 + 0x40 + 0x3f, | ||
| 44 | .flags = IORESOURCE_MEM, | ||
| 45 | }, | ||
| 46 | [2] = { | ||
| 47 | .start = IRQ_DM9000, | ||
| 48 | .end = IRQ_DM9000, | ||
| 49 | .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL, | ||
| 50 | } | ||
| 51 | }; | ||
| 52 | |||
| 53 | static struct platform_device bast_device_dm9k = { | ||
| 54 | .name = "dm9000", | ||
| 55 | .id = 0, | ||
| 56 | .num_resources = ARRAY_SIZE(bast_dm9k_resource), | ||
| 57 | .resource = bast_dm9k_resource, | ||
| 58 | }; | ||
| 59 | |||
| 60 | Note the setting of the IRQ trigger flag in bast_dm9k_resource[2].flags, | ||
| 61 | as this will generate a warning if it is not present. The trigger from | ||
| 62 | the flags field will be passed to request_irq() when registering the IRQ | ||
| 63 | handler to ensure that the IRQ is setup correctly. | ||
| 64 | |||
| 65 | This shows a typical platform device, without the optional configuration | ||
| 66 | platform data supplied. The next example uses the same resources, but adds | ||
| 67 | the optional platform data to pass extra configuration data: | ||
| 68 | |||
| 69 | static struct dm9000_plat_data bast_dm9k_platdata = { | ||
| 70 | .flags = DM9000_PLATF_16BITONLY, | ||
| 71 | }; | ||
| 72 | |||
| 73 | static struct platform_device bast_device_dm9k = { | ||
| 74 | .name = "dm9000", | ||
| 75 | .id = 0, | ||
| 76 | .num_resources = ARRAY_SIZE(bast_dm9k_resource), | ||
| 77 | .resource = bast_dm9k_resource, | ||
| 78 | .dev = { | ||
| 79 | .platform_data = &bast_dm9k_platdata, | ||
| 80 | } | ||
| 81 | }; | ||
| 82 | |||
| 83 | The platform data is defined in include/linux/dm9000.h and described below. | ||
| 84 | |||
| 85 | |||
| 86 | Platform data | ||
| 87 | ------------- | ||
| 88 | |||
| 89 | Extra platform data for the DM9000 can describe the IO bus width to the | ||
| 90 | device, whether or not an external PHY is attached to the device and | ||
| 91 | the availability of an external configuration EEPROM. | ||
| 92 | |||
| 93 | The flags for the platform data .flags field are as follows: | ||
| 94 | |||
| 95 | DM9000_PLATF_8BITONLY | ||
| 96 | |||
| 97 | The IO should be done with 8bit operations. | ||
| 98 | |||
| 99 | DM9000_PLATF_16BITONLY | ||
| 100 | |||
| 101 | The IO should be done with 16bit operations. | ||
| 102 | |||
| 103 | DM9000_PLATF_32BITONLY | ||
| 104 | |||
| 105 | The IO should be done with 32bit operations. | ||
| 106 | |||
| 107 | DM9000_PLATF_EXT_PHY | ||
| 108 | |||
| 109 | The chip is connected to an external PHY. | ||
| 110 | |||
| 111 | DM9000_PLATF_NO_EEPROM | ||
| 112 | |||
| 113 | This can be used to signify that the board does not have an | ||
| 114 | EEPROM, or that the EEPROM should be hidden from the user. | ||
| 115 | |||
| 116 | DM9000_PLATF_SIMPLE_PHY | ||
| 117 | |||
| 118 | Switch to using the simpler PHY polling method which does not | ||
| 119 | try and read the MII PHY state regularly. This is only available | ||
| 120 | when using the internal PHY. See the section on link state polling | ||
| 121 | for more information. | ||
| 122 | |||
| 123 | The config symbol DM9000_FORCE_SIMPLE_PHY_POLL, Kconfig entry | ||
| 124 | "Force simple NSR based PHY polling" allows this flag to be | ||
| 125 | forced on at build time. | ||
| 126 | |||
| 127 | |||
| 128 | PHY Link state polling | ||
| 129 | ---------------------- | ||
| 130 | |||
| 131 | The driver keeps track of the link state and informs the network core | ||
| 132 | about link (carrier) availablilty. This is managed by several methods | ||
| 133 | depending on the version of the chip and on which PHY is being used. | ||
| 134 | |||
| 135 | For the internal PHY, the original (and currently default) method is | ||
| 136 | to read the MII state, either when the status changes if we have the | ||
| 137 | necessary interrupt support in the chip or every two seconds via a | ||
| 138 | periodic timer. | ||
| 139 | |||
| 140 | To reduce the overhead for the internal PHY, there is now the option | ||
| 141 | of using the DM9000_FORCE_SIMPLE_PHY_POLL config, or DM9000_PLATF_SIMPLE_PHY | ||
| 142 | platform data option to read the summary information without the | ||
| 143 | expensive MII accesses. This method is faster, but does not print | ||
| 144 | as much information. | ||
| 145 | |||
| 146 | When using an external PHY, the driver currently has to poll the MII | ||
| 147 | link status as there is no method for getting an interrupt on link change. | ||
| 148 | |||
| 149 | |||
| 150 | DM9000A / DM9000B | ||
| 151 | ----------------- | ||
| 152 | |||
| 153 | These chips are functionally similar to the DM9000E and are supported easily | ||
| 154 | by the same driver. The features are: | ||
| 155 | |||
| 156 | 1) Interrupt on internal PHY state change. This means that the periodic | ||
| 157 | polling of the PHY status may be disabled on these devices when using | ||
| 158 | the internal PHY. | ||
| 159 | |||
| 160 | 2) TCP/UDP checksum offloading, which the driver does not currently support. | ||
| 161 | |||
| 162 | |||
| 163 | ethtool | ||
| 164 | ------- | ||
| 165 | |||
| 166 | The driver supports the ethtool interface for access to the driver | ||
| 167 | state information, the PHY state and the EEPROM. | ||

| 254 | If your server does not seem to be able to receive UDP traffic as fast as it | ||

| 256 | the network stack buffers as large as they need to be to support high UDP | ||

| 270 | Additional Configurations | ||
| 271 | ========================= | ||
| 272 | |||
| 273 | Configuring the Driver on Different Distributions | ||
| 274 | ------------------------------------------------- | ||
| 275 | Configuring a network driver to load properly when the system is started is | ||
| 276 | distribution dependent. Typically, the configuration process involves adding | ||
| 277 | an alias line to /etc/modprobe.conf as well as editing other system startup | ||
| 278 | scripts and/or configuration files. Many popular Linux distributions ship | ||
| 279 | with tools to make these changes for you. To learn the proper way to | ||
| 280 | configure a network device for your system, refer to your distribution | ||
| 281 | documentation. If during this process you are asked for the driver or module | ||
| 282 | name, the name for the Linux Base Driver for the Intel 10GbE Family of | ||
| 283 | Adapters is ixgb. | ||
| 284 | |||
| 285 | Viewing Link Messages | ||
| 286 | --------------------- | ||
| 287 | Link messages will not be displayed to the console if the distribution is | ||
| 288 | restricting system messages. In order to see network driver link messages on | ||
| 289 | your console, set dmesg to eight by entering the following: | ||
| 290 | |||
| 291 | dmesg -n 8 | ||
| 292 | |||
| 293 | NOTE: This setting is not saved across reboots. | ||
| 294 | |||
| 295 | |||
| 296 | Jumbo Frames | ||
| 297 | ------------ | ||
| 298 | The driver supports Jumbo Frames for all adapters. Jumbo Frames support is | ||
| 299 | enabled by changing the MTU to a value larger than the default of 1500. | ||
| 300 | The maximum value for the MTU is 16114. Use the ifconfig command to | ||
| 301 | increase the MTU size. For example: | ||
| 302 | |||
| 303 | ifconfig ethx mtu 9000 up | ||
| 304 | |||
| 305 | The maximum MTU setting for Jumbo Frames is 16114. This value coincides | ||
| 306 | with the maximum Jumbo Frames size of 16128. | ||
| 307 | |||
| 308 | |||
| 309 | Ethtool | ||
| 310 | ------- | ||
| 311 | The driver utilizes the ethtool interface for driver configuration and | ||
| 312 | diagnostics, as well as displaying statistical information. Ethtool | ||
| 313 | version 1.6 or later is required for this functionality. | ||
| 314 | |||
| 315 | The latest release of ethtool can be found from | ||
| 316 | http://sourceforge.net/projects/gkernel | ||
| 317 | |||
| 318 | NOTE: Ethtool 1.6 only supports a limited set of ethtool options. Support | ||
| 319 | for a more complete ethtool feature set can be enabled by upgrading | ||
| 320 | to the latest version. | ||
| 321 | |||
| 322 | |||
| 323 | NAPI | ||
| 324 | ---- | ||
| 325 | |||
| 326 | NAPI (Rx polling mode) is supported in the ixgb driver. NAPI is enabled | ||

| 332 | Known Issues/Troubleshooting | ||
| 333 | ============================ | ||
| 334 | |||
| 335 | NOTE: After installing the driver, if your Intel Network Connection is not | ||
| 336 | working, verify in the "In This Release" section of the readme that you have | ||
| 337 | installed the correct driver. | ||

| 339 | Intel(R) PRO/10GbE CX4 Server Adapter Cable Interoperability Issue with | ||
| 340 | Fujitsu XENPAK Module in SmartBits Chassis | ||
| 341 | --------------------------------------------------------------------- | ||
| 342 | Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 | ||
| 343 | Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits | ||
| 344 | chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni. | ||
| 345 | The CRC errors may be received either by the Intel(R) PRO/10GbE CX4 | ||
| 346 | Server adapter or the SmartBits. If this situation occurs using a different | ||
| 347 | cable assembly may resolve the issue. | ||
| 348 | |||
| 349 | CX4 Server Adapter Cable Interoperability Issues with HP Procurve 3400cl | ||
| 350 | Switch Port | ||
| 351 | ------------------------------------------------------------------------ | ||
| 352 | Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server | ||
| 353 | adapter is connected to an HP Procurve 3400cl switch port using short cables | ||
| 354 | (1 m or shorter). If this situation occurs, using a longer cable may resolve | ||
| 355 | the issue. | ||
| 356 | |||
| 357 | Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that | ||
| 358 | Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC | ||
| 359 | errors may be received either by the CX4 Server adapter or at the switch. If | ||
| 360 | this situation occurs, using a different cable assembly may resolve the issue. | ||
| 361 | |||
| 362 | |||
| 363 | Jumbo Frames System Requirement | ||
| 364 | ------------------------------- | ||
| 365 | Memory allocation failures have been observed on Linux systems with 64 MB | ||
| 366 | of RAM or less that are running Jumbo Frames. If you are using Jumbo | ||
| 367 | Frames, your system may require more than the advertised minimum | ||
| 368 | requirement of 64 MB of system memory. | ||
| 369 | |||
| 370 | |||
| 371 | Performance Degradation with Jumbo Frames | ||
| 372 | ----------------------------------------- | ||
| 373 | Degradation in throughput performance may be observed in some Jumbo frames | ||
| 374 | environments. If this is observed, increasing the application's socket buffer | ||
| 375 | size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help. | ||
| 376 | See the specific application manual and /usr/src/linux*/Documentation/ | ||
| 377 | networking/ip-sysctl.txt for more details. | ||
| 378 | |||
| 379 | |||
| 380 | Allocating Rx Buffers when Using Jumbo Frames | ||
| 381 | --------------------------------------------- | ||
| 382 | Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if | ||
| 383 | the available memory is heavily fragmented. This issue may be seen with PCI-X | ||
| 384 | adapters or with packet split disabled. This can be reduced or eliminated | ||
| 385 | by changing the amount of available memory for receive buffer allocation, by | ||
| 386 | increasing /proc/sys/vm/min_free_kbytes. | ||
| 387 | |||
| 388 | |||
| 389 | Multiple Interfaces on Same Ethernet Broadcast Network | ||
| 390 | ------------------------------------------------------ | ||
| 391 | Due to the default ARP behavior on Linux, it is not possible to have | ||
| 392 | one system on two IP networks in the same Ethernet broadcast domain | ||
| 393 | (non-partitioned switch) behave as expected. All Ethernet interfaces | ||
| 394 | will respond to IP traffic for any IP address assigned to the system. | ||
| 395 | This results in unbalanced receive traffic. | ||
| 396 | |||
| 397 | If you have multiple interfaces in a server, do either of the following: | ||
| 398 | |||
| 399 | - Turn on ARP filtering by entering: | ||
| 400 | echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter | ||
| 401 | |||
| 402 | - Install the interfaces in separate broadcast domains - either in | ||
| 403 | different switches or in a switch partitioned to VLANs. | ||
| 404 | |||
| 405 | |||
| 406 | UDP Stress Test Dropped Packet Issue | ||
| 407 | -------------------------------------- | ||
| 408 | Under small packets UDP stress test with 10GbE driver, the Linux system | ||
| 409 | may drop UDP packets due to the fullness of socket buffers. You may want | ||
| 410 | to change the driver's Flow Control variables to the minimum value for | ||
| 411 | controlling packet reception. | ||
| 412 | |||
| 413 | |||
| 414 | Tx Hangs Possible Under Stress | ||
| 415 | ------------------------------ | ||
| 416 | Under stress conditions, if TX hangs occur, turning off TSO | ||
| 417 | "ethtool -K eth0 tso off" may resolve the problem. | ||

| 9 | Introduction | ||
| 10 | |||
| 11 | mac80211_hwsim is a Linux kernel module that can be used to simulate | ||
| 12 | arbitrary number of IEEE 802.11 radios for mac80211. It can be used to | ||
| 13 | test most of the mac80211 functionality and user space tools (e.g., | ||
| 14 | hostapd and wpa_supplicant) in a way that matches very closely with | ||
| 15 | the normal case of using real WLAN hardware. From the mac80211 view | ||
| 16 | point, mac80211_hwsim is yet another hardware driver, i.e., no changes | ||
| 17 | to mac80211 are needed to use this testing tool. | ||
| 18 | |||
| 19 | The main goal for mac80211_hwsim is to make it easier for developers | ||
| 20 | to test their code and work with new features to mac80211, hostapd, | ||
| 21 | and wpa_supplicant. The simulated radios do not have the limitations | ||
| 22 | of real hardware, so it is easy to generate an arbitrary test setup | ||
| 23 | and always reproduce the same setup for future tests. In addition, | ||
| 24 | since all radio operation is simulated, any channel can be used in | ||
| 25 | tests regardless of regulatory rules. | ||
| 26 | |||
| 27 | mac80211_hwsim kernel module has a parameter 'radios' that can be used | ||
| 28 | to select how many radios are simulated (default 2). This allows | ||
| 29 | configuration of both very simply setups (e.g., just a single access | ||
| 30 | point and a station) or large scale tests (multiple access points with | ||
| 31 | hundreds of stations). | ||
| 32 | |||
| 33 | mac80211_hwsim works by tracking the current channel of each virtual | ||
| 34 | radio and copying all transmitted frames to all other radios that are | ||
| 35 | currently enabled and on the same channel as the transmitting | ||
| 36 | radio. Software encryption in mac80211 is used so that the frames are | ||
| 37 | actually encrypted over the virtual air interface to allow more | ||
| 38 | complete testing of encryption. | ||
| 39 | |||
| 40 | A global monitoring netdev, hwsim#, is created independent of | ||
| 41 | mac80211. This interface can be used to monitor all transmitted frames | ||
| 42 | regardless of channel. | ||
| 43 | |||
| 44 | |||
| 45 | Simple example | ||
| 46 | |||
| 47 | This example shows how to use mac80211_hwsim to simulate two radios: | ||
| 48 | one to act as an access point and the other as a station that | ||
| 49 | associates with the AP. hostapd and wpa_supplicant are used to take | ||
| 50 | care of WPA2-PSK authentication. In addition, hostapd is also | ||
| 51 | processing access point side of association. | ||
| 52 | |||
| 53 | Please note that the current Linux kernel does not enable AP mode, so a | ||
| 54 | simple patch is needed to enable AP mode selection: | ||

| 35 | Finally, the base driver should indicate that it is a multiqueue device. The | ||
| 36 | feature flag NETIF_F_MULTI_QUEUE should be added to the netdev->features | ||
| 37 | bitmap on device initialization. Below is an example from e1000: | ||
| 38 | |||
| 39 | #ifdef CONFIG_E1000_MQ | ||
| 40 | if ( (adapter->hw.mac.type == e1000_82571) || | ||

| 45 | |||
| 46 | |||
| 47 | Section 2: Qdisc support for multiqueue devices | ||
| 48 | ----------------------------------------------- | ||
| 49 | |||
| 50 | Currently two qdiscs support multiqueue devices. A new round-robin qdisc, | ||
| 51 | sch_rr, and sch_prio. The qdisc is responsible for classifying the skb's to | ||
| 52 | bands and queues, and will store the queue mapping into skb->queue_mapping. | ||
| 53 | Use this field in the base driver to determine which queue to send the skb | ||
| 54 | to. | ||
| 55 | |||
| 56 | sch_rr has been added for hardware that doesn't want scheduling policies from | ||
| 57 | software, so it's a straight round-robin qdisc. It uses the same syntax and | ||
| 58 | classification priomap that sch_prio uses, so it should be intuitive to | ||
| 59 | configure for people who've used sch_prio. | ||
| 60 | |||
| 61 | In order to utilitize the multiqueue features of the qdiscs, the network | ||
| 62 | device layer needs to enable multiple queue support. This can be done by | ||
| 63 | selecting NETDEVICES_MULTIQUEUE under Drivers. | ||
| 64 | |||
| 65 | The PRIO qdisc naturally plugs into a multiqueue device. If | ||
| 66 | NETDEVICES_MULTIQUEUE is selected, then on qdisc load, the number of | ||
| 67 | bands requested is compared to the number of queues on the hardware. If they | ||
| 68 | are equal, it sets a one-to-one mapping up between the queues and bands. If | ||
| 69 | they're not equal, it will not load the qdisc. This is the same behavior | ||
| 70 | for RR. Once the association is made, any skb that is classified will have | ||
| 71 | skb->queue_mapping set, which will allow the driver to properly queue skb's | ||
| 72 | to multiple queues. | ||
| 73 | |||
| 74 | |||
| 75 | Section 3: Brief howto using PRIO and RR for multiqueue devices | ||
| 76 | --------------------------------------------------------------- | ||
| 77 | |||
| 78 | The userspace command 'tc,' part of the iproute2 package, is used to configure | ||
| 79 | qdiscs. To add the PRIO qdisc to your network device, assuming the device is | ||
| 80 | called eth0, run the following command: | ||
| 81 | |||
| 82 | # tc qdisc add dev eth0 root handle 1: prio bands 4 multiqueue | ||
| 83 | |||
| 84 | This will create 4 bands, 0 being highest priority, and associate those bands | ||
| 85 | to the queues on your NIC. Assuming eth0 has 4 Tx queues, the band mapping | ||
| 86 | would look like: | ||
| 87 | |||
| 88 | band 0 => queue 0 | ||
| 89 | band 1 => queue 1 | ||
| 90 | band 2 => queue 2 | ||
| 91 | band 3 => queue 3 | ||
| 92 | |||
| 93 | Traffic will begin flowing through each queue if your TOS values are assigning | ||
| 94 | traffic across the various bands. For example, ssh traffic will always try to | ||
| 95 | go out band 0 based on TOS -> Linux priority conversion (realtime traffic), | ||
| 96 | so it will be sent out queue 0. ICMP traffic (pings) fall into the "normal" | ||
| 97 | traffic classification, which is band 1. Therefore pings will be send out | ||
| 98 | queue 1 on the NIC. | ||
| 99 | |||
| 100 | Note the use of the multiqueue keyword. This is only in versions of iproute2 | ||
| 101 | that support multiqueue networking devices; if this is omitted when loading | ||
| 102 | a qdisc onto a multiqueue device, the qdisc will load and operate the same | ||
| 103 | if it were loaded onto a single-queue device (i.e. - sends all traffic to | ||
| 104 | queue 0). | ||
| 105 | |||
| 106 | Another alternative to multiqueue band allocation can be done by using the | ||
| 107 | multiqueue option and specify 0 bands. If this is the case, the qdisc will | ||
| 108 | allocate the number of bands to equal the number of queues that the device | ||
| 109 | reports, and bring the qdisc online. | ||
| 110 | |||
| 111 | The behavior of tc filters remains the same, where it will override TOS priority | ||
| 112 | classification. | ||

| 11 | The rfkill switch subsystem offers support for keys often found on laptops | 14 | 1. Introduction: |
| 12 | to enable wireless devices like WiFi and Bluetooth. | 15 | |
| 16 | The rfkill switch subsystem exists to add a generic interface to circuitry that | ||
| 17 | can enable or disable the signal output of a wireless *transmitter* of any | ||
| 18 | type. By far, the most common use is to disable radio-frequency transmitters. | ||
| 13 | 19 | ||
| 14 | This is done by providing the user 3 possibilities: | 20 | Note that disabling the signal output means that the the transmitter is to be |
| 15 | 1 - The rfkill system handles all events; userspace is not aware of events. | 21 | made to not emit any energy when "blocked". rfkill is not about blocking data |
| 16 | 2 - The rfkill system handles all events; userspace is informed about the events. | 22 | transmissions, it is about blocking energy emission. |
| 17 | 3 - The rfkill system does not handle events; userspace handles all events. | ||
| 18 | 23 | ||
| 19 | The buttons to enable and disable the wireless radios are important in | 24 | The rfkill subsystem offers support for keys and switches often found on |
| 25 | laptops to enable wireless devices like WiFi and Bluetooth, so that these keys | ||
| 26 | and switches actually perform an action in all wireless devices of a given type | ||
| 27 | attached to the system. | ||
| 28 | |||
| 29 | The buttons to enable and disable the wireless transmitters are important in | ||
| 20 | situations where the user is for example using his laptop on a location where | 30 | situations where the user is for example using his laptop on a location where |
| 21 | wireless radios _must_ be disabled (e.g. airplanes). | 31 | radio-frequency transmitters _must_ be disabled (e.g. airplanes). |
| 22 | Because of this requirement, userspace support for the keys should not be | 32 | |
| 23 | made mandatory. Because userspace might want to perform some additional smarter | 33 | Because of this requirement, userspace support for the keys should not be made |
| 24 | tasks when the key is pressed, rfkill still provides userspace the possibility | 34 | mandatory. Because userspace might want to perform some additional smarter |
| 25 | to take over the task to handle the key events. | 35 | tasks when the key is pressed, rfkill provides userspace the possibility to |
| 36 | take over the task to handle the key events. | ||
| 37 | |||
| 38 | =============================================================================== | ||
| 39 | 2: Implementation details | ||
| 40 | |||
| 41 | The rfkill subsystem is composed of various components: the rfkill class, the | ||
| 42 | rfkill-input module (an input layer handler), and some specific input layer | ||
| 43 | events. | ||
| 44 | |||
| 45 | The rfkill class provides kernel drivers with an interface that allows them to | ||
| 46 | know when they should enable or disable a wireless network device transmitter. | ||
| 47 | This is enabled by the CONFIG_RFKILL Kconfig option. | ||
| 48 | |||
| 49 | The rfkill class support makes sure userspace will be notified of all state | ||
| 50 | changes on rfkill devices through uevents. It provides a notification chain | ||
| 51 | for interested parties in the kernel to also get notified of rfkill state | ||
| 52 | changes in other drivers. It creates several sysfs entries which can be used | ||
| 53 | by userspace. See section "Userspace support". | ||
| 54 | |||
| 55 | The rfkill-input module provides the kernel with the ability to implement a | ||
| 56 | basic response when the user presses a key or button (or toggles a switch) | ||
| 57 | related to rfkill functionality. It is an in-kernel implementation of default | ||
| 58 | policy of reacting to rfkill-related input events and neither mandatory nor | ||
| 59 | required for wireless drivers to operate. It is enabled by the | ||
| 60 | CONFIG_RFKILL_INPUT Kconfig option. | ||
| 61 | |||
| 62 | rfkill-input is a rfkill-related events input layer handler. This handler will | ||
| 63 | listen to all rfkill key events and will change the rfkill state of the | ||
| 64 | wireless devices accordingly. With this option enabled userspace could either | ||
| 65 | do nothing or simply perform monitoring tasks. | ||
| 66 | |||
| 67 | The rfkill-input module also provides EPO (emergency power-off) functionality | ||
| 68 | for all wireless transmitters. This function cannot be overridden, and it is | ||
| 69 | always active. rfkill EPO is related to *_RFKILL_ALL input layer events. | ||
| 70 | |||
| 71 | |||
| 72 | Important terms for the rfkill subsystem: | ||
| 73 | |||
| 74 | In order to avoid confusion, we avoid the term "switch" in rfkill when it is | ||
| 75 | referring to an electronic control circuit that enables or disables a | ||
| 76 | transmitter. We reserve it for the physical device a human manipulates | ||
| 77 | (which is an input device, by the way): | ||
| 78 | |||
| 79 | rfkill switch: | ||
| 80 | |||
| 81 | A physical device a human manipulates. Its state can be perceived by | ||
| 82 | the kernel either directly (through a GPIO pin, ACPI GPE) or by its | ||
| 83 | effect on a rfkill line of a wireless device. | ||
| 84 | |||
| 85 | rfkill controller: | ||
| 86 | |||
| 87 | A hardware circuit that controls the state of a rfkill line, which a | ||
| 88 | kernel driver can interact with *to modify* that state (i.e. it has | ||
| 89 | either write-only or read/write access). | ||
| 90 | |||
| 91 | rfkill line: | ||
| 92 | |||
| 93 | An input channel (hardware or software) of a wireless device, which | ||
| 94 | causes a wireless transmitter to stop emitting energy (BLOCK) when it | ||
| 95 | is active. Point of view is extremely important here: rfkill lines are | ||
| 96 | always seen from the PoV of a wireless device (and its driver). | ||
| 97 | |||
| 98 | soft rfkill line/software rfkill line: | ||
| 99 | |||
| 100 | A rfkill line the wireless device driver can directly change the state | ||
| 101 | of. Related to rfkill_state RFKILL_STATE_SOFT_BLOCKED. | ||
| 102 | |||
| 103 | hard rfkill line/hardware rfkill line: | ||
| 104 | |||
| 105 | A rfkill line that works fully in hardware or firmware, and that cannot | ||
| 106 | be overridden by the kernel driver. The hardware device or the | ||
| 107 | firmware just exports its status to the driver, but it is read-only. | ||
| 108 | Related to rfkill_state RFKILL_STATE_HARD_BLOCKED. | ||
| 109 | |||
| 110 | The enum rfkill_state describes the rfkill state of a transmitter: | ||
| 111 | |||
| 112 | When a rfkill line or rfkill controller is in the RFKILL_STATE_UNBLOCKED state, | ||
| 113 | the wireless transmitter (radio TX circuit for example) is *enabled*. When the | ||
| 114 | it is in the RFKILL_STATE_SOFT_BLOCKED or RFKILL_STATE_HARD_BLOCKED, the | ||
| 115 | wireless transmitter is to be *blocked* from operating. | ||
| 116 | |||
| 117 | RFKILL_STATE_SOFT_BLOCKED indicates that a call to toggle_radio() can change | ||
| 118 | that state. RFKILL_STATE_HARD_BLOCKED indicates that a call to toggle_radio() | ||
| 119 | will not be able to change the state and will return with a suitable error if | ||
| 120 | attempts are made to set the state to RFKILL_STATE_UNBLOCKED. | ||
| 121 | |||
| 122 | RFKILL_STATE_HARD_BLOCKED is used by drivers to signal that the device is | ||
| 123 | locked in the BLOCKED state by a hardwire rfkill line (typically an input pin | ||
| 124 | that, when active, forces the transmitter to be disabled) which the driver | ||
| 125 | CANNOT override. | ||
| 126 | |||
| 127 | Full rfkill functionality requires two different subsystems to cooperate: the | ||
| 128 | input layer and the rfkill class. The input layer issues *commands* to the | ||
| 129 | entire system requesting that devices registered to the rfkill class change | ||
| 130 | state. The way this interaction happens is not complex, but it is not obvious | ||
| 131 | either: | ||
| 132 | |||
| 133 | Kernel Input layer: | ||
| 134 | |||
| 135 | * Generates KEY_WWAN, KEY_WLAN, KEY_BLUETOOTH, SW_RFKILL_ALL, and | ||
| 136 | other such events when the user presses certain keys, buttons, or | ||
| 137 | toggles certain physical switches. | ||
| 138 | |||
| 139 | THE INPUT LAYER IS NEVER USED TO PROPAGATE STATUS, NOTIFICATIONS OR THE | ||
| 140 | KIND OF STUFF AN ON-SCREEN-DISPLAY APPLICATION WOULD REPORT. It is | ||
| 141 | used to issue *commands* for the system to change behaviour, and these | ||
| 142 | commands may or may not be carried out by some kernel driver or | ||
| 143 | userspace application. It follows that doing user feedback based only | ||
| 144 | on input events is broken, as there is no guarantee that an input event | ||
| 145 | will be acted upon. | ||
| 146 | |||
| 147 | Most wireless communication device drivers implementing rfkill | ||
| 148 | functionality MUST NOT generate these events, and have no reason to | ||
| 149 | register themselves with the input layer. Doing otherwise is a common | ||
| 150 | misconception. There is an API to propagate rfkill status change | ||
| 151 | information, and it is NOT the input layer. | ||
| 152 | |||
| 153 | rfkill class: | ||
| 154 | |||
| 155 | * Calls a hook in a driver to effectively change the wireless | ||
| 156 | transmitter state; | ||
| 157 | * Keeps track of the wireless transmitter state (with help from | ||
| 158 | the driver); | ||
| 159 | * Generates userspace notifications (uevents) and a call to a | ||
| 160 | notification chain (kernel) when there is a wireless transmitter | ||
| 161 | state change; | ||
| 162 | * Connects a wireless communications driver with the common rfkill | ||
| 163 | control system, which, for example, allows actions such as | ||
| 164 | "switch all bluetooth devices offline" to be carried out by | ||
| 165 | userspace or by rfkill-input. | ||
| 166 | |||
| 167 | THE RFKILL CLASS NEVER ISSUES INPUT EVENTS. THE RFKILL CLASS DOES | ||
| 168 | NOT LISTEN TO INPUT EVENTS. NO DRIVER USING THE RFKILL CLASS SHALL | ||
| 169 | EVER LISTEN TO, OR ACT ON RFKILL INPUT EVENTS. Doing otherwise is | ||
| 170 | a layering violation. | ||
| 171 | |||
| 172 | Most wireless data communication drivers in the kernel have just to | ||
| 173 | implement the rfkill class API to work properly. Interfacing to the | ||
| 174 | input layer is not often required (and is very often a *bug*) on | ||
| 175 | wireless drivers. | ||
| 176 | |||
| 177 | Platform drivers often have to attach to the input layer to *issue* | ||
| 178 | (but never to listen to) rfkill events for rfkill switches, and also to | ||
| 179 | the rfkill class to export a control interface for the platform rfkill | ||
| 180 | controllers to the rfkill subsystem. This does NOT mean the rfkill | ||
| 181 | switch is attached to a rfkill class (doing so is almost always wrong). | ||
| 182 | It just means the same kernel module is the driver for different | ||
| 183 | devices (rfkill switches and rfkill controllers). | ||
| 184 | |||
| 185 | |||
| 186 | Userspace input handlers (uevents) or kernel input handlers (rfkill-input): | ||
| 187 | |||
| 188 | * Implements the policy of what should happen when one of the input | ||
| 189 | layer events related to rfkill operation is received. | ||
| 190 | * Uses the sysfs interface (userspace) or private rfkill API calls | ||
| 191 | to tell the devices registered with the rfkill class to change | ||
| 192 | their state (i.e. translates the input layer event into real | ||
| 193 | action). | ||
| 194 | * rfkill-input implements EPO by handling EV_SW SW_RFKILL_ALL 0 | ||
| 195 | (power off all transmitters) in a special way: it ignores any | ||
| 196 | overrides and local state cache and forces all transmitters to the | ||
| 197 | RFKILL_STATE_SOFT_BLOCKED state (including those which are already | ||
| 198 | supposed to be BLOCKED). Note that the opposite event (power on all | ||
| 199 | transmitters) is handled normally. | ||
| 200 | |||
| 201 | Userspace uevent handler or kernel platform-specific drivers hooked to the | ||
| 202 | rfkill notifier chain: | ||
| 203 | |||
| 204 | * Taps into the rfkill notifier chain or to KOBJ_CHANGE uevents, | ||
| 205 | in order to know when a device that is registered with the rfkill | ||
| 206 | class changes state; | ||
| 207 | * Issues feedback notifications to the user; | ||
| 208 | * In the rare platforms where this is required, synthesizes an input | ||
| 209 | event to command all *OTHER* rfkill devices to also change their | ||
| 210 | statues when a specific rfkill device changes state. | ||
| 211 | |||
| 212 | |||
| 213 | =============================================================================== | ||
| 214 | 3: Kernel driver guidelines | ||
| 215 | |||
| 216 | Remember: point-of-view is everything for a driver that connects to the rfkill | ||
| 217 | subsystem. All the details below must be measured/perceived from the point of | ||
| 218 | view of the specific driver being modified. | ||
| 219 | |||
| 220 | The first thing one needs to know is whether his driver should be talking to | ||
| 221 | the rfkill class or to the input layer. In rare cases (platform drivers), it | ||
| 222 | could happen that you need to do both, as platform drivers often handle a | ||
| 223 | variety of devices in the same driver. | ||
| 224 | |||
| 225 | Do not mistake input devices for rfkill controllers. The only type of "rfkill | ||
| 226 | switch" device that is to be registered with the rfkill class are those | ||
| 227 | directly controlling the circuits that cause a wireless transmitter to stop | ||
| 228 | working (or the software equivalent of them), i.e. what we call a rfkill | ||
| 229 | controller. Every other kind of "rfkill switch" is just an input device and | ||
| 230 | MUST NOT be registered with the rfkill class. | ||
| 231 | |||
| 232 | A driver should register a device with the rfkill class when ALL of the | ||
| 233 | following conditions are met (they define a rfkill controller): | ||
| 234 | |||
| 235 | 1. The device is/controls a data communications wireless transmitter; | ||
| 236 | |||
| 237 | 2. The kernel can interact with the hardware/firmware to CHANGE the wireless | ||
| 238 | transmitter state (block/unblock TX operation); | ||
| 239 | |||
| 240 | 3. The transmitter can be made to not emit any energy when "blocked": | ||
| 241 | rfkill is not about blocking data transmissions, it is about blocking | ||
| 242 | energy emission; | ||
| 243 | |||
| 244 | A driver should register a device with the input subsystem to issue | ||
| 245 | rfkill-related events (KEY_WLAN, KEY_BLUETOOTH, KEY_WWAN, KEY_WIMAX, | ||
| 246 | SW_RFKILL_ALL, etc) when ALL of the folowing conditions are met: | ||
| 247 | |||
| 248 | 1. It is directly related to some physical device the user interacts with, to | ||
| 249 | command the O.S./firmware/hardware to enable/disable a data communications | ||
| 250 | wireless transmitter. | ||
| 251 | |||
| 252 | Examples of the physical device are: buttons, keys and switches the user | ||
| 253 | will press/touch/slide/switch to enable or disable the wireless | ||
| 254 | communication device. | ||
| 255 | |||
| 256 | 2. It is NOT slaved to another device, i.e. there is no other device that | ||
| 257 | issues rfkill-related input events in preference to this one. | ||
| 26 | 258 | ||
| 27 | The system inside the kernel has been split into 2 separate sections: | 259 | Please refer to the corner cases and examples section for more details. |
| 28 | 1 - RFKILL | ||
| 29 | 2 - RFKILL_INPUT | ||
| 30 | 260 | ||
| 31 | The first option enables rfkill support and will make sure userspace will | 261 | When in doubt, do not issue input events. For drivers that should generate |
| 32 | be notified of any events through the input device. It also creates several | 262 | input events in some platforms, but not in others (e.g. b43), the best solution |
| 33 | sysfs entries which can be used by userspace. See section "Userspace support". | 263 | is to NEVER generate input events in the first place. That work should be |
| 264 | deferred to a platform-specific kernel module (which will know when to generate | ||
| 265 | events through the rfkill notifier chain) or to userspace. This avoids the | ||
| 266 | usual maintenance problems with DMI whitelisting. | ||
| 34 | 267 | ||
| 35 | The second option provides an rfkill input handler. This handler will | ||
| 36 | listen to all rfkill key events and will toggle the radio accordingly. | ||
| 37 | With this option enabled userspace could either do nothing or simply | ||
| 38 | perform monitoring tasks. | ||
| 39 | 268 | ||
| 269 | Corner cases and examples: | ||
| 40 | ==================================== | 270 | ==================================== |
| 41 | 2: Driver support | ||
| 42 | 271 | ||
| 43 | To build a driver with rfkill subsystem support, the driver should | 272 | 1. If the device is an input device that, because of hardware or firmware, |
| 44 | depend on the Kconfig symbol RFKILL; it should _not_ depend on | 273 | causes wireless transmitters to be blocked regardless of the kernel's will, it |
| 45 | RKFILL_INPUT. | 274 | is still just an input device, and NOT to be registered with the rfkill class. |
| 46 | 275 | ||
| 47 | Unless key events trigger an interrupt to which the driver listens, polling | 276 | 2. If the wireless transmitter switch control is read-only, it is an input |
| 48 | will be required to determine the key state changes. For this the input | 277 | device and not to be registered with the rfkill class (and maybe not to be made |
| 49 | layer providers the input-polldev handler. | 278 | an input layer event source either, see below). |
| 50 | 279 | ||
| 51 | A driver should implement a few steps to correctly make use of the | 280 | 3. If there is some other device driver *closer* to the actual hardware the |
| 52 | rfkill subsystem. First for non-polling drivers: | 281 | user interacted with (the button/switch/key) to issue an input event, THAT is |
| 282 | the device driver that should be issuing input events. | ||
| 53 | 283 | ||
| 54 | - rfkill_allocate() | 284 | E.g: |
| 55 | - input_allocate_device() | 285 | [RFKILL slider switch] -- [GPIO hardware] -- [WLAN card rf-kill input] |
| 56 | - rfkill_register() | 286 | (platform driver) (wireless card driver) |
| 57 | - input_register_device() | 287 | |
| 288 | The user is closer to the RFKILL slide switch plaform driver, so the driver | ||
| 289 | which must issue input events is the platform driver looking at the GPIO | ||
| 290 | hardware, and NEVER the wireless card driver (which is just a slave). It is | ||
| 291 | very likely that there are other leaves than just the WLAN card rf-kill input | ||
| 292 | (e.g. a bluetooth card, etc)... | ||
| 293 | |||
| 294 | On the other hand, some embedded devices do this: | ||
| 295 | |||
| 296 | [RFKILL slider switch] -- [WLAN card rf-kill input] | ||
| 297 | (wireless card driver) | ||
| 298 | |||
| 299 | In this situation, the wireless card driver *could* register itself as an input | ||
| 300 | device and issue rf-kill related input events... but in order to AVOID the need | ||
| 301 | for DMI whitelisting, the wireless card driver does NOT do it. Userspace (HAL) | ||
| 302 | or a platform driver (that exists only on these embedded devices) will do the | ||
| 303 | dirty job of issuing the input events. | ||
| 304 | |||
| 305 | |||
| 306 | COMMON MISTAKES in kernel drivers, related to rfkill: | ||
| 307 | ==================================== | ||
| 308 | |||
| 309 | 1. NEVER confuse input device keys and buttons with input device switches. | ||
| 310 | |||
| 311 | 1a. Switches are always set or reset. They report the current state | ||
| 312 | (on position or off position). | ||
| 313 | |||
| 314 | 1b. Keys and buttons are either in the pressed or not-pressed state, and | ||
| 315 | that's it. A "button" that latches down when you press it, and | ||
| 316 | unlatches when you press it again is in fact a switch as far as input | ||
| 317 | devices go. | ||
| 318 | |||
| 319 | Add the SW_* events you need for switches, do NOT try to emulate a button using | ||
| 320 | KEY_* events just because there is no such SW_* event yet. Do NOT try to use, | ||
| 321 | for example, KEY_BLUETOOTH when you should be using SW_BLUETOOTH instead. | ||
| 322 | |||
| 323 | 2. Input device switches (sources of EV_SW events) DO store their current state | ||
| 324 | (so you *must* initialize it by issuing a gratuitous input layer event on | ||
| 325 | driver start-up and also when resuming from sleep), and that state CAN be | ||
| 326 | queried from userspace through IOCTLs. There is no sysfs interface for this, | ||
| 327 | but that doesn't mean you should break things trying to hook it to the rfkill | ||
| 328 | class to get a sysfs interface :-) | ||
| 329 | |||
| 330 | 3. Do not issue *_RFKILL_ALL events by default, unless you are sure it is the | ||
| 331 | correct event for your switch/button. These events are emergency power-off | ||
| 332 | events when they are trying to turn the transmitters off. An example of an | ||
| 333 | input device which SHOULD generate *_RFKILL_ALL events is the wireless-kill | ||
| 334 | switch in a laptop which is NOT a hotkey, but a real switch that kills radios | ||
| 335 | in hardware, even if the O.S. has gone to lunch. An example of an input device | ||
| 336 | which SHOULD NOT generate *_RFKILL_ALL events by default, is any sort of hot | ||
| 337 | key that does nothing by itself, as well as any hot key that is type-specific | ||
| 338 | (e.g. the one for WLAN). | ||
| 339 | |||
| 340 | |||
| 341 | 3.1 Guidelines for wireless device drivers | ||
| 342 | ------------------------------------------ | ||
| 343 | |||
| 344 | 1. Each independent transmitter in a wireless device (usually there is only one | ||
| 345 | transmitter per device) should have a SINGLE rfkill class attached to it. | ||
| 346 | |||
| 347 | 2. If the device does not have any sort of hardware assistance to allow the | ||
| 348 | driver to rfkill the device, the driver should emulate it by taking all actions | ||
| 349 | required to silence the transmitter. | ||
| 350 | |||
| 351 | 3. If it is impossible to silence the transmitter (i.e. it still emits energy, | ||
| 352 | even if it is just in brief pulses, when there is no data to transmit and there | ||
| 353 | is no hardware support to turn it off) do NOT lie to the users. Do not attach | ||
| 354 | it to a rfkill class. The rfkill subsystem does not deal with data | ||
| 355 | transmission, it deals with energy emission. If the transmitter is emitting | ||
| 356 | energy, it is not blocked in rfkill terms. | ||
| 357 | |||
| 358 | 4. It doesn't matter if the device has multiple rfkill input lines affecting | ||
| 359 | the same transmitter, their combined state is to be exported as a single state | ||
| 360 | per transmitter (see rule 1). | ||
| 361 | |||
| 362 | This rule exists because users of the rfkill subsystem expect to get (and set, | ||
| 363 | when possible) the overall transmitter rfkill state, not of a particular rfkill | ||
| 364 | line. | ||
| 365 | |||
| 366 | Example of a WLAN wireless driver connected to the rfkill subsystem: | ||
| 367 | -------------------------------------------------------------------- | ||
| 368 | |||
| 369 | A certain WLAN card has one input pin that causes it to block the transmitter | ||
| 370 | and makes the status of that input pin available (only for reading!) to the | ||
| 371 | kernel driver. This is a hard rfkill input line (it cannot be overridden by | ||
| 372 | the kernel driver). | ||
| 373 | |||
| 374 | The card also has one PCI register that, if manipulated by the driver, causes | ||
| 375 | it to block the transmitter. This is a soft rfkill input line. | ||
| 376 | |||
| 377 | It has also a thermal protection circuitry that shuts down its transmitter if | ||
| 378 | the card overheats, and makes the status of that protection available (only for | ||
| 379 | reading!) to the kernel driver. This is also a hard rfkill input line. | ||
| 380 | |||
| 381 | If either one of these rfkill lines are active, the transmitter is blocked by | ||
| 382 | the hardware and forced offline. | ||
| 383 | |||
| 384 | The driver should allocate and attach to its struct device *ONE* instance of | ||
| 385 | the rfkill class (there is only one transmitter). | ||
| 386 | |||
| 387 | It can implement the get_state() hook, and return RFKILL_STATE_HARD_BLOCKED if | ||
| 388 | either one of its two hard rfkill input lines are active. If the two hard | ||
| 389 | rfkill lines are inactive, it must return RFKILL_STATE_SOFT_BLOCKED if its soft | ||
| 390 | rfkill input line is active. Only if none of the rfkill input lines are | ||
| 391 | active, will it return RFKILL_STATE_UNBLOCKED. | ||
| 58 | 392 | ||
| 59 | For polling drivers: | 393 | If it doesn't implement the get_state() hook, it must make sure that its calls |
| 394 | to rfkill_force_state() are enough to keep the status always up-to-date, and it | ||
| 395 | must do a rfkill_force_state() on resume from sleep. | ||
| 60 | 396 | ||
| 397 | Every time the driver gets a notification from the card that one of its rfkill | ||
| 398 | lines changed state (polling might be needed on badly designed cards that don't | ||
| 399 | generate interrupts for such events), it recomputes the rfkill state as per | ||
| 400 | above, and calls rfkill_force_state() to update it. | ||
| 401 | |||
| 402 | The driver should implement the toggle_radio() hook, that: | ||
| 403 | |||
| 404 | 1. Returns an error if one of the hardware rfkill lines are active, and the | ||
| 405 | caller asked for RFKILL_STATE_UNBLOCKED. | ||
| 406 | |||
| 407 | 2. Activates the soft rfkill line if the caller asked for state | ||
| 408 | RFKILL_STATE_SOFT_BLOCKED. It should do this even if one of the hard rfkill | ||
| 409 | lines are active, effectively double-blocking the transmitter. | ||
| 410 | |||
| 411 | 3. Deactivates the soft rfkill line if none of the hardware rfkill lines are | ||
| 412 | active and the caller asked for RFKILL_STATE_UNBLOCKED. | ||
| 413 | |||
| 414 | =============================================================================== | ||
| 415 | 4: Kernel API | ||
| 416 | |||
| 417 | To build a driver with rfkill subsystem support, the driver should depend on | ||
| 418 | (or select) the Kconfig symbol RFKILL; it should _not_ depend on RKFILL_INPUT. | ||
| 419 | |||
| 420 | The hardware the driver talks to may be write-only (where the current state | ||
| 421 | of the hardware is unknown), or read-write (where the hardware can be queried | ||
| 422 | about its current state). | ||
| 423 | |||
| 424 | The rfkill class will call the get_state hook of a device every time it needs | ||
| 425 | to know the *real* current state of the hardware. This can happen often. | ||
| 426 | |||
| 427 | Some hardware provides events when its status changes. In these cases, it is | ||
| 428 | best for the driver to not provide a get_state hook, and instead register the | ||
| 429 | rfkill class *already* with the correct status, and keep it updated using | ||
| 430 | rfkill_force_state() when it gets an event from the hardware. | ||
| 431 | |||
| 432 | There is no provision for a statically-allocated rfkill struct. You must | ||
| 433 | use rfkill_allocate() to allocate one. | ||
| 434 | |||
| 435 | You should: | ||
| 61 | - rfkill_allocate() | 436 | - rfkill_allocate() |
| 62 | - input_allocate_polled_device() | 437 | - modify rfkill fields (flags, name) |
| 438 | - modify state to the current hardware state (THIS IS THE ONLY TIME | ||
| 439 | YOU CAN ACCESS state DIRECTLY) | ||
| 63 | - rfkill_register() | 440 | - rfkill_register() |
| 64 | - input_register_polled_device() | ||
| 65 | 441 | ||
| 66 | When a key event has been detected, the correct event should be | 442 | The only way to set a device to the RFKILL_STATE_HARD_BLOCKED state is through |
| 67 | sent over the input device which has been registered by the driver. | 443 | a suitable return of get_state() or through rfkill_force_state(). |
| 68 | 444 | ||
| 69 | ==================================== | 445 | When a device is in the RFKILL_STATE_HARD_BLOCKED state, the only way to switch |
| 70 | 3: Userspace support | 446 | it to a different state is through a suitable return of get_state() or through |
| 447 | rfkill_force_state(). | ||
| 448 | |||
| 449 | If toggle_radio() is called to set a device to state RFKILL_STATE_SOFT_BLOCKED | ||
| 450 | when that device is already at the RFKILL_STATE_HARD_BLOCKED state, it should | ||
| 451 | not return an error. Instead, it should try to double-block the transmitter, | ||
| 452 | so that its state will change from RFKILL_STATE_HARD_BLOCKED to | ||
| 453 | RFKILL_STATE_SOFT_BLOCKED should the hardware blocking cease. | ||
| 71 | 454 | ||
| 72 | For each key an input device will be created which will send out the correct | 455 | Please refer to the source for more documentation. |
| 73 | key event when the rfkill key has been pressed. | 456 | |
| 457 | =============================================================================== | ||
| 458 | 5: Userspace support | ||
| 459 | |||
| 460 | rfkill devices issue uevents (with an action of "change"), with the following | ||
| 461 | environment variables set: | ||
| 462 | |||
| 463 | RFKILL_NAME | ||
| 464 | RFKILL_STATE | ||
| 465 | RFKILL_TYPE | ||
| 466 | |||
| 467 | The ABI for these variables is defined by the sysfs attributes. It is best | ||
| 468 | to take a quick look at the source to make sure of the possible values. | ||
| 469 | |||
| 470 | It is expected that HAL will trap those, and bridge them to DBUS, etc. These | ||
| 471 | events CAN and SHOULD be used to give feedback to the user about the rfkill | ||
| 472 | status of the system. | ||
| 473 | |||
| 474 | Input devices may issue events that are related to rfkill. These are the | ||
| 475 | various KEY_* events and SW_* events supported by rfkill-input.c. | ||
| 476 | |||
| 477 | ******IMPORTANT****** | ||
| 478 | When rfkill-input is ACTIVE, userspace is NOT TO CHANGE THE STATE OF AN RFKILL | ||
| 479 | SWITCH IN RESPONSE TO AN INPUT EVENT also handled by rfkill-input, unless it | ||
| 480 | has set to true the user_claim attribute for that particular switch. This rule | ||
| 481 | is *absolute*; do NOT violate it. | ||
| 482 | ******IMPORTANT****** | ||
| 483 | |||
| 484 | Userspace must not assume it is the only source of control for rfkill switches. | ||
| 485 | Their state CAN and WILL change due to firmware actions, direct user actions, | ||
| 486 | and the rfkill-input EPO override for *_RFKILL_ALL. | ||
| 487 | |||
| 488 | When rfkill-input is not active, userspace must initiate a rfkill status | ||
| 489 | change by writing to the "state" attribute in order for anything to happen. | ||
| 490 | |||
| 491 | Take particular care to implement EV_SW SW_RFKILL_ALL properly. When that | ||
| 492 | switch is set to OFF, *every* rfkill device *MUST* be immediately put into the | ||
| 493 | RFKILL_STATE_SOFT_BLOCKED state, no questions asked. | ||
| 74 | 494 | ||
| 75 | The following sysfs entries will be created: | 495 | The following sysfs entries will be created: |
| 76 | 496 | ||
| 77 | name: Name assigned by driver to this key (interface or driver name). | 497 | name: Name assigned by driver to this key (interface or driver name). |

| 79 | state: Current state of the key. 1: On, 0: Off. | 499 | state: Current state of the transmitter |
| 500 | 0: RFKILL_STATE_SOFT_BLOCKED | ||
| 501 | transmitter is forced off, but one can override it | ||
| 502 | by a write to the state attribute; | ||
| 503 | 1: RFKILL_STATE_UNBLOCKED | ||
| 504 | transmiter is NOT forced off, and may operate if | ||
| 505 | all other conditions for such operation are met | ||
| 506 | (such as interface is up and configured, etc); | ||
| 507 | 2: RFKILL_STATE_HARD_BLOCKED | ||
| 508 | transmitter is forced off by something outside of | ||
| 509 | the driver's control. One cannot set a device to | ||
| 510 | this state through writes to the state attribute; | ||
| 80 | claim: 1: Userspace handles events, 0: Kernel handles events | 511 | claim: 1: Userspace handles events, 0: Kernel handles events |
| 81 | 512 | ||
| 82 | Both the "state" and "claim" entries are also writable. For the "state" entry | 513 | Both the "state" and "claim" entries are also writable. For the "state" entry |
| 83 | this means that when 1 or 0 is written all radios, not yet in the requested | 514 | this means that when 1 or 0 is written, the device rfkill state (if not yet in |

| 522 | |||
| 523 | A note about input devices and EV_SW events: | ||
| 524 | |||
| 525 | In order to know the current state of an input device switch (like | ||
| 526 | SW_RFKILL_ALL), you will need to use an IOCTL. That information is not | ||
| 527 | available through sysfs in a generic way at this time, and it is not available | ||
| 528 | through the rfkill class AT ALL. | ||
