Hi Linus, please pull from: git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release Highlights: The Embedded Controller driver removes a GPE race condition. Turns out we had been impatient with old machines, and simply increasing an error timeout will make some of them work. The platform specific drivers that use ACPI now send their button events to the input layer. Updated ibm-acpi driver from new sub-maintainer. SGI is starting to leverage ACPI support, God bless them. This will update the files shown below. thanks! -Len ps. a plain patch is also available here: ftp://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release/2.6.20/acpi-release-20060707-2.6.20-rc1.diff.gz Documentation/ibm-acpi.txt | 151 ++- MAINTAINERS | 9 arch/i386/kernel/acpi/boot.c | 22 drivers/acpi/Kconfig | 17 drivers/acpi/ac.c | 6 drivers/acpi/acpi_memhotplug.c | 2 drivers/acpi/asus_acpi.c | 69 + drivers/acpi/battery.c | 22 drivers/acpi/button.c | 223 +++- drivers/acpi/container.c | 2 drivers/acpi/dock.c | 153 ++- drivers/acpi/ec.c | 347 +++---- drivers/acpi/events/evmisc.c | 1 drivers/acpi/executer/exmutex.c | 6 drivers/acpi/fan.c | 6 drivers/acpi/glue.c | 10 drivers/acpi/hotkey.c | 5 drivers/acpi/i2c_ec.c | 2 drivers/acpi/ibm_acpi.c | 1046 +++++++++++++++++++---- drivers/acpi/namespace/nsxfobj.c | 44 drivers/acpi/numa.c | 2 drivers/acpi/osl.c | 5 drivers/acpi/pci_bind.c | 4 drivers/acpi/pci_irq.c | 2 drivers/acpi/pci_link.c | 8 drivers/acpi/pci_root.c | 13 drivers/acpi/power.c | 6 drivers/acpi/processor_core.c | 14 drivers/acpi/processor_idle.c | 14 drivers/acpi/processor_perflib.c | 10 drivers/acpi/processor_thermal.c | 6 drivers/acpi/processor_throttling.c | 6 drivers/acpi/sbs.c | 24 drivers/acpi/sleep/wakeup.c | 6 drivers/acpi/tables.c | 2 drivers/acpi/tables/tbxface.c | 54 + drivers/acpi/thermal.c | 30 drivers/acpi/toshiba_acpi.c | 89 + drivers/acpi/utilities/utdebug.c | 5 drivers/acpi/utilities/utmutex.c | 16 drivers/acpi/utils.c | 4 drivers/acpi/video.c | 100 +- drivers/misc/msi-laptop.c | 3 drivers/usb/misc/appledisplay.c | 2 drivers/video/aty/aty128fb.c | 2 drivers/video/aty/atyfb_base.c | 2 drivers/video/aty/radeon_backlight.c | 2 drivers/video/backlight/backlight.c | 7 drivers/video/nvidia/nv_backlight.c | 2 drivers/video/riva/fbdev.c | 2 include/acpi/acpixf.h | 7 include/asm-i386/acpi.h | 26 include/asm-x86_64/acpi.h | 26 include/linux/backlight.h | 2 kernel/power/disk.c | 8 kernel/power/main.c | 2 56 files changed, 1896 insertions(+), 760 deletions(-) through these commits: Adrian Bunk (2): ACPI: make drivers/acpi/ec.c:ec_ecdt static ACPI: fix NULL check in drivers/acpi/osl.c Akinobu Mita (2): ACPI: fix single linked list manipulation ACPI: prevent processor module from loading on failures Alexey Starikovskiy (15): ACPI: ec: Allow for write semantics in any command.

Also add a new routine used to unload an ACPI table of a given type and "id" - acpi_unload_table_id(). The implementation of this new routine was almost a direct copy of existing routine acpi_unload_table() - only difference being that it only removes a specific table id instead of ALL tables of a given type. The SN hotplug driver (sgi_hotplug.c) now uses both of these interfaces to dynamically load and unload SSDT ACPI tables. Also, a few other ACPI routines now used by the SN hotplug driver are exported (since the driver can be a loadable module): acpi_ns_map_handle_to_node acpi_ns_convert_entry_to_handle acpi_ns_get_next_node Signed-off-by: Aaron Young <ayoung@xxxxxxx> Cc: Greg KH <greg@xxxxxxxxx> Cc: "Luck, Tony" <tony.luck@xxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxx> Signed-off-by: Len Brown <len.brown@xxxxxxxxx> commit a8274d57afb83e4954ddcb3f8b7dd1c03a379bd4 Author: James Simmons <jsimmons@xxxxxxxxxxxxx> Date: Tue Dec 19 12:56:16 2006 -0800 fbdev: update after backlight argument change Update the frambuffer drivers to the backlight_device_registers changes.

This patch: Add dev argument for backlight_device_register to link the class device to real device object. The platform specific driver should find a way to get the real device object for their video device.

This patch implements acpi_video_get_next_level properly. It had to change a few constants at the top of the file because they were (apparently) wrong, but it appears to work on my Dell Inspiron e1405 (with BIOS A05 only--BIOS A04 doesn't seem to send ACPI video hotkey events).

When the watchdog timer expires, the equivalent action of a "fan enable" command is executed. The watchdog timer is reset at every reception of a fan control command that could change the state of the fan itself. This command is meant to be used by userspace fan control daemons, to make sure the fan is never left set to an unsafe level because of userspace problems. Users of the X31/X40/X41 "speed" command are on their own, the current implementation of "speed" is just too incomplete to be used safely, anyway. Better to never use it, and just use the "level" command instead. The watchdog is programmed using echo "watchdog <number>" > fan, where number is the number of seconds to wait before doing an "enable", and zero disables the watchdog.

If the BIOS and the ACPI DSDT also do not initialize it, then the initial status of that register does not correspond to reality. On all reported buggy machines, EC 0x2f will read 0x07 (fan level 7) upon cold boot, when the EC is actually in mode 0x80 (auto mode). Since returning a text string ("unknown") would break a number of userspace programs, instead we correct the reading for the most probably correct answer, and return it is in auto mode. The workaround flags the status and level as unknown on module load/kernel boot, until we are certain at least one fan control command was issued, either by us, or by something else. We don't work around the bug by doing a "fan enable" at module load/startup (which would initialize the EC register) because it is not known if these ThinkPad ACPI DSDT might have set the fan to level 7 instead of "auto" (we don't know if they can do this or not) due to a thermal condition, and we don't want to override that, should they be capable of it. We should be setting the workaround flag to "status known" upon resume, as both reports and a exaustive search on the DSDT tables at acpi.sf.net show that the DSDTs always enable the fan on resume, thus working around the bug. But since we don't have suspend/resume handlers in ibm-acpi yet and the "EC register 0x2f was modified" logic is likely to catch the change anyway, we don't.

It uses a DMI match to detect ThinkPads with a new-style embedded controller, that are known to have forward- compatible register maps and use 0x00 to fill in non-used registers and export thermal sensors at EC offsets 0x78-7F and 0xC0-C7. Direct ACPI EC register access is implemented for 8-sensor and 16-sensor new-style ThinkPad controller firmwares as an experimental feature. The code does some limited sanity checks on the temperatures read through EC access, and will default to the old ACPI TMP0-7 mode if anything is amiss. Userspace ABI is not changed for 8 sensors, but /proc/acpi/ibm/thermal is extended for 16 sensors if the firmware supports 16 sensors. A documentation update is also provided. The information about the ThinkPad register map was determined by studying ibm-acpi "ecdump" output from various ThinkPad models, submitted by subscribers of the linux-thinkpad mailinglist. Futher information was gathered from the DSDT tables, as they describe the EC register map in recent ThinkPads. DSDT source shows that TMP0-7 access and direct register access are actually the same thing on these firmwares, but unfortunately IBM never did update their DSDT EC register map to export TMP8-TMP15 for the second range of sensors.
