* ACPI: thinkpad-acpi: export EV_SW SW_RADIO eventsHenrique de Moraes Holschuh2007-07-21
| | | | | | | | | | | | | | | | The expected user case for the radio slider switch on a ThinkPad includes interfacing to applications, so that the user gets an offer to find and associate with a wireless network when the switch is changed from disabled to enabled (ThinkVantage suite). Export the information about the switch state, and switch change events as an EV_SW SW_RADIO event over the input layer.

* ACPI: thinkpad-acpi: make the input event mode the defaultHenrique de Moraes Holschuh2007-07-21
| | | | | | | | | | | | | | Make the input layer the default way to deal with thinkpad-acpi hot keys, but add a kernel config option to retain the old way of doing things. This means we map a lot more keys to useful stuff by default, and also that we enable hot key handling by default on driver load (like Windows does). The documentation for proper use of this resource is also updated.

* ACPI: thinkpad-acpi: add input device support to hotkey subdriverHenrique de Moraes Holschuh2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | Add input device support to the hotkey subdriver. Hot keys that have a valid keycode mapping are reported through the input layer if the input device is open. Otherwise, they will be reported as ACPI events, as they were before. Scan codes are reported (using EV_MSC MSC_SCAN events) along with EV_KEY KEY_UNKNOWN events. For backwards compatibility purposes, hot keys that used to be reported through ACPI events are not mapped to anything meaningful by default. Userspace is supposed to remap them if it wants to use the input device for hot key reporting. This patch is based on a patch by Richard Hughes <hughsient@gmail.com>.

* ACPI: thinkpad-acpi: checkpoint sysfs interface version due to hotkeyHenrique de Moraes Holschuh2007-07-21
| | | | | | | | | | | | | The change in the size of the hotkey mask, the hability to report the keys that use the higher bits, and the addition of the hotkey_radio_sw attribute are important enough features to warrant increasing the minor field of the sysfs interface version. Also, document a bit better how and when the thinkpad-acpi sysfs interface version will be updated.

* ACPI: thinkpad-acpi: export to sysfs the state of the radio slider switchHenrique de Moraes Holschuh2007-07-21
| | | | | | | | | | | | | | | | | Some ThinkPad models, notably the T60 and X60, have a slider switch to enable and disable the radios. The switch has the capability of force-disabling the radios in hardware on most models, and it is supposed to affect all radios (WLAN, WWAN, BlueTooth). Export the switch state as a sysfs attribute, on ThinkPads where it is available. Thanks to Henning Schild for asking for this feature, and for tracking down the EC register that holds the radio switch state.

* ACPI: thinkpad-acpi: export hotkey maximum masksHenrique de Moraes Holschuh2007-07-21
| | | | | | | | | | | | | The firmware knows how many hot keys it supports, so export this information in a sysfs attribute. And the driver knows which keys are always handled by the firmware in all known ThinkPad models too, so export this information as well in a sysfs attribute. Unless you know which events need to be handled in a passive way, do *not* enable hotkeys that are always handled by the firmware.

* ACPI: thinkpad-acpi: enable more hotkeysHenrique de Moraes Holschuh2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | Revise ACPI HKEY functionality to better interface with the firmware, and enable up to 32 regular hotkeys, instead of just 16 of them. Ouch. This takes care of most keys one used to have to do CMOS NVRAM polling on, and should drop the need for tpb, thinkpad-keys, and other such 5Hz NVRAM polling power vampires on most modern ThinkPads ;-) And, just to add insult to injury, this was sort of working since forever through the procfs interface, but nobody noticed or tried an echo 0xffffffff > /proc/acpi/ibm/hotkey and told me it would generate weird events. ARGH! Thanks to Richard Hughes for kicking off the work that ended up with this discovery, and to Matthew Garret for calling my attention to the fact that newer ThinkPads were indeed generating ACPI GPEs when such hot keys were pressed.

* x86_64: fake pxm-to-node mapping for fake numaDavid Rientjes2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For NUMA emulation, our SLIT should represent the true NUMA topology of the system but our proximity domain to node ID mapping needs to reflect the emulated state. When NUMA emulation has successfully setup fake nodes on the system, a new function, acpi_fake_nodes() is called. This function determines the proximity domain (_PXM) for each true node found on the system. It then finds which emulated nodes have been allocated on this true node as determined by its starting address. The node ID to PXM mapping is changed so that each fake node ID points to the PXM of the true node that it is located on. If the machine failed to register a SLIT, then we assume there is no special requirement for emulated node affinity so we use the default LOCAL_DISTANCE, which is newly exported to this code, as our measurement if the emulated nodes appear in the same PXM. Otherwise, we use REMOTE_DISTANCE. PXM_INVAL and NID_INVAL are also exported to the ACPI header file so that we can compare node_to_pxm() results in generic code (in this case, the SRAT code).

| | | | | | | | | | | | | | | | | | | | | In acpi_scan_nodes(), we immediately return -1 if acpi_numa <= 0, meaning we haven't detected any underlying ACPI topology or we have explicitly disabled its use from the command-line with numa=noacpi. acpi_table_print_srat_entry() and acpi_table_parse_srat() are only referenced within drivers/acpi/numa.c, so we can mark them as static and remove their prototypes from the header file. Likewise, pxm_to_node_map[] and node_to_pxm_map[] are only used within drivers/acpi/numa.c, so we mark them as static and remove their externs from the header file. The automatic 'result' variable is unused in acpi_numa_init(), so it's removed.

* dm io: fix panic on large requestMilan Broz2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | Flush workqueue before releasing bioset and mopools in dm-crypt. There can be finished but not yet released request. Call chain causing oops: run workqueue dec_pending bio_endio(...); <remove device request - remove mempool> mempool_free(io, cc->io_pool); This usually happens when cryptsetup create temporary luks mapping in the beggining of crypt device activation. When dm-core calls destructor crypt_dtr, no new request are possible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing sparc64 mini_rtc driver can handle CMOS based rtcs trivially with just a few lines of code and the simplifies things tremendously. Tested on SB1500. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current scheme works on static interpretation of text names, which is wrong. The output-device setting, for example, must be resolved via an alias or similar to a full path name to the console device. Paths also contain an optional set of 'options', which starts with a colon at the end of the path. The option area is used to specify which of two serial ports ('a' or 'b') the path refers to when a device node drives multiple ports. 'a' is assumed if the option specification is missing. This was caught by the UltraSPARC-T1 simulator. The 'output-device' property was set to 'ttya' and we didn't pick upon the fact that this is an OBP alias set to '/virtual-devices/console'. Instead we saw it as the first serial console device, instead of the hypervisor console. The infrastructure is now there to take advantage of this to resolve the console correctly even in multi-head situations in fbcon too. Thanks to Greg Onufer for the bug report.
