2007-05-10acpi,msi-laptop: Fall back to EC polling mode for MSI laptop specific EC ↵Lennart Poettering
commands The ACPI EC that is used in MSI laptops knows some non-standard commands for changing the screen brighntess and a few other things, which are used by the msi-laptop.c driver. Unfortunately for these commands no GPE events for IBF and OBF are triggered. Since nowadays the EC code uses the ec_intr=1 mode by default, this causes these operations to timeout, although they don't fail. In result, all operations that you can do with the msi-laptop.c driver take more or less 1s to complete, which is awfully slow. In one of the more recent kernels (2.6.20?) the EC subsystem has been revamped. With that change the EC timeout has been increased. before that increase the MSI EC accesses were slow -- but not *that* slow, hence I took notice of this limitation of the MSI EC hardware only very recently. The standard EC operations on the MSI EC as defined in the ACPI spec support GPE events properly. The following patch adds a new argument "force_poll" to the ec_transaction() function (and friends). If set to 1, the function will poll for IBF/OBF even if ec_intr=1 is enabled. If set to 0 the current behaviour is used. The msi-laptop driver is modified to make use of this new flag, so that OBF/IBF is polled for the special MSI EC transactions -- but only for them.

2007-05-02PCI: Cleanup the includes of <linux/pci.h>Jean Delvare
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.

2007-04-28ACPI: thinkpad-acpi: map ENXIO to EINVAL for fan sysfsHenrique de Moraes Holschuh
Currently, all fan control operations return ENXIO if unsupported operations are requested, but return EINVAL if invalid fan modes are requested on a given ThinkPad. This is not strictly correct for sysfs, so map ENXIO to EINVAL in the sysfs attribute store handlers, as we do benefit from the ENXIO in other parts of the driver code.

2007-04-28ACPI: thinkpad-acpi: add a fan-control feature master toggleHenrique de Moraes Holschuh
Len Brown considers that an active by default fan control interface in laptops may be too close to giving users enough rope. There is a good chance he is quite correct on this, especially if someone decides to use that interface in applets and users are not aware of its risks. This patch adds a master switch to thinkpad-acpi that enables or disables the entire fan-control feature as a module parameter: "fan_control". It defaults to disabled. Set it to non-zero to enable fan control. Also, the patch removes the expermiental status from fan control, since it is stable enough to not be called experimental, and the master switch makes it safe enough to do so.

2007-04-25ACPI: thinkpad-acpi: add a safety net for TPEC fan control modeHenrique de Moraes Holschuh
The Linux ThinkPad community is not positive that all ThinkPads that do HFSP EC fan control do implement full-speed and auto modes, some of the earlier ones supporting HFSP might not. If the EC ignores the AUTO or FULL-SPEED bits, it will pay attention to the lower three bits that set the fan level. And as thinkpad-acpi was leaving these set to zero, it would stop(!) the fan, which is Not A Good Thing. So, as a safety net, we now make sure to also set the fan level part of the HFSP register to speed 7 for full-speed, and a minimum of speed 4 for auto mode.

2007-04-25ACPI: thinkpad-acpi: add sysfs support to fan subdriverHenrique de Moraes Holschuh
Export sysfs attributes to monitor and control the internal thinkpad fan (some thinkpads have more than one fan, but thinkpad-acpi doesn't support the second fan yet). The sysfs interface follows the hwmon design guide for fan devices. Also, fix some stray "thermal" files in the fan procfs description that have been there forever, and officially support "full-speed" as the name for the PWM-disabled state of the fan controller to keep it in line with the hwmon interface. It is much better a name for that mode than the unobvious "disengaged" anyway. Change the procfs interface to also accept full-speed as a fan level, but still report it as disengaged for backwards compatibility.

2007-04-25ACPI: thinkpad-acpi: add sysfs support to the thermal subdriverHenrique de Moraes Holschuh
Export thinkpad thermal sensors to sysfs, following the hwmon specification for thermal monitoring sensors. ThinkPad thermal monitoring is done by the EC. Sensors can show up or disappear at runtime when they are inside hotswappable hardware, such as batteries. Sensors that are not available return -ENXIO when accessed. Up to 16 thermal sensors are supported on new firmware (but nobody has reported a ThinkPad with more than 12 sensors so far), and 8 sensors are supported on older firmware. Thermal sensor mapping is model-specific. Precision varies, it is 1 degree Celcius on new ThinkPads, but higher on some older models.
