* driver model: constify attribute groupsDavid Brownell2009-09-15
| | | | | | | | | | Let attribute group vectors be declared "const". We'd like to let most attribute metadata live in read-only sections... this is a start. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* IB/ipath: Misc changes to prepare for IB7220 introductionArthur Jones2008-04-17
| | | | | | | | | | | The patch adds a number of minor changes to support newer HCAs: - New send buffer control bits - New error condition bits - Locking and initialization changes - More send buffers Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ipath: EEPROM support for 7220 devices, robustness improvements, cleanupMichael Albaugh2008-04-17
| | | | | | | | | | Add support for reading newer card's EEPROMs while continuing to support older EEPROMs. Also, add support for the temperature sensor if present. Signed-off-by: Michael Albaugh <Michael.Albaugh@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ipath: Provide I/O bus speeds for diagnostic purposesArthur Jones2008-04-17
| | | | | | | | | | Modern I/O buses like PCIe and HT can be configured for multiple speeds and widths. When an ipath HCA seems to have lower than expected performance, it is very useful to be able to display what the driver thinks the bus speed is.

* IB/ipath: New sysfs entries to control 7220 featuresMichael Albaugh2008-01-25
| | | | | | | | | IBA7220 includes many more configurable IB settings. Getting/setting these is now grouped into a pair of chip specific functions accessed via function pointers. Provide sysfs access to these settings. Signed-off-by: Michael Albaugh <michael.albaugh@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ipath: Fix crash on unload introduced by sysfs changesRoland Dreier2008-01-25
| | | | | | | | | | | | | | | Commit 23b9c1ab ("Infiniband: make ipath driver use default driver groups.") introduced a bug in the ipath driver where ipath_device_create_group() fell through into the error path, even on success, which meant that the sysfs groups it created would always get removed right away. This made ipath_device_remove_group() hit the BUG_ON() in sysfs_remove_group() when it tried to remove those groups a second time. Correct the return path so that the groups stick around until they are supposed to be cleaned up. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* Infiniband: make ipath driver use default driver groups.Greg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | | | Make the ipath driver use the new driver functions so that it does not touch the sysfs portion of the driver structure. We also remove the redundant symlink from the device back to the driver, as it is already in the sysfs tree. Any userspace tools should be using the standard symlink, not some driver specific one.

* IB/ipath: Add ability to set the LMC via the sysfs debugging interfaceRalph Campbell2007-10-09
| | | | | | | | | This patch adds the ability to set the LMC via a sysfs file as if the SM sent a SubnSet(PortInfo) MAD. It is useful for debugging when no SM is running. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* IB/ipath: Log "active" time and some errors to EEPROMMichael Albaugh2007-07-09
| | | | | | | | | | We currently track various errors, now we enhance that capability by logging some of them to EEPROM. We also now log a cumulative "active" time defined by traffic though the InfiniPath HCA beyond the normal SM traffic.

* IB/ipath: Support blinking LEDs with an led_override fileMichael Albaugh2007-07-09
| | | | | | | | | | | | | | | When we want to find an InfiniPath HCA in a rack of nodes, it is often expeditious to blink the status LEDs via a userspace /sys file. A write-only led_override "file" is published per device. Writes to this file are interpreted as (string form) numbers, and the resulting value sent to ipath_set_led_override(). The upper eight bits are interpretted as a 4.4 fixed-point "frequency in Hertz", and the bottom two 4-bit values are alternately (D0..3, then D4..7) used by the board-specific LED-setting function to override the normal state.

* PCI: Cleanup the includes of <linux/pci.h>Jean Delvare2007-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed that many source files include <linux/pci.h> while they do not appear to need it. Here is an attempt to clean it all up. In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually. My tests covered 66% of the affected files, so there could be false positives remaining. Untested files are: arch/alpha/kernel/err_common.c arch/alpha/kernel/err_ev6.c arch/alpha/kernel/err_ev7.c arch/ia64/sn/kernel/huberror.c arch/ia64/sn/kernel/xpnet.c arch/m68knommu/kernel/dma.c arch/mips/lib/iomap.c arch/powerpc/platforms/pseries/ras.c arch/ppc/8260_io/enet.c arch/ppc/8260_io/fcc_enet.c arch/ppc/8xx_io/enet.c arch/ppc/syslib/ppc4xx_sgdma.c arch/sh64/mach-cayman/iomap.c arch/xtensa/kernel/xtensa_ksyms.c arch/xtensa/platform-iss/setup.c drivers/i2c/busses/i2c-at91.c drivers/i2c/busses/i2c-mpc.c drivers/media/video/saa711x.c drivers/misc/hdpuftrs/hdpu_cpustate.c drivers/misc/hdpuftrs/hdpu_nexus.c drivers/net/au1000_eth.c drivers/net/fec_8xx/fec_main.c drivers/net/fec_8xx/fec_mii.c drivers/net/fs_enet/fs_enet-main.c drivers/net/fs_enet/mac-fcc.c drivers/net/fs_enet/mac-fec.c drivers/net/fs_enet/mac-scc.c drivers/net/fs_enet/mii-bitbang.c drivers/net/fs_enet/mii-fec.c drivers/net/ibm_emac/ibm_emac_core.c drivers/net/lasi_82596.c drivers/parisc/hppb.c drivers/sbus/sbus.c drivers/video/g364fb.c drivers/video/platinumfb.c drivers/video/stifb.c drivers/video/valkyriefb.c include/asm-arm/arch-ixp4xx/dma.h sound/oss/au1550_ac97.c I would welcome test reports for these files. I am fine with removing the untested files from the patch if the general opinion is that these changes aren't safe. The tested part would still be nice to have.

| | | | | | | | | | | | | | Remove ips namespace from infinipath drivers. This renames ips_common.h to ipath_common.h. Definitions, data structures, etc. that were not used by kernel modules have moved to user-only headers. All names including ips have been renamed to ipath. Some names have had an ipath prefix added.

* IB/ipath: sysfs and ipathfs support for core driverBryan O'Sullivan2006-03-31
The ipathfs filesystem contains files that are not appropriate for sysfs, because they contain binary data. The hierarchy is simple; the top-level directory contains driver-wide attribute files, while numbered subdirectories contain per-device attribute files. Our userspace code currently expects this filesystem to be mounted on /ipathfs, but a final location has not yet been chosen.
