But the link driver can easily figure out whether to turn on IRQ balancing based on the IRQ model (PIC/IOAPIC/etc), so we can get rid of that external interface. It's better for the driver to figure this out at init-time. If we set it externally via the x86 code, the interface reduces modularity, and we depend on the fact that acpi_process_madt() happens before we process the kernel command line.

The application panel contains the following keys: lock, mobility center, eco, info. Whilst key 4 might be more appropriate for help then key 2, I've done things the S6410 way. I can confirm that backlight control is functional, and that the lock key activates the Gnome screensaver as expected.

Currently it is possible to load above drivers and let both poke on the brightness HW registers, the video and vendor specific ACPI drivers -> bad. This patch provides the basic support to check for BIOS capabilities before driver loading time. Driver specific modifications are in separate follow up patches. "acpi_backlight=vendor" Prever vendor driver over ACPI driver for backlight. "acpi_backlight=video" (default) Prever ACPI driver over vendor driver for backlight.

In fact, they only worked because the ACPI device of the discrete, the wrong one, got used (via int10). So ACPI functions were poking on the wrong hardware used which is a sever bug. The next patch provides support for above ThinkPads to be able to switch brightness via the legacy thinkpad_acpi driver and automatically detect when to use it. Original commit message from Matthew Garrett: Vendors often ship machines with a choice of integrated or discrete graphics, and use the same DSDT for both. As a result, the ACPI video module will locate devices that may not exist on this specific platform. Attempt to determine whether the device exists or not, and abort the device creation if it doesn't. http://bugzilla.kernel.org/show_bug.cgi?id=9614 Signed-off-by: Thomas Renninger <trenn@xxxxxxx> Acked-by: Zhang Rui <rui.zhang@xxxxxxxxx> Signed-off-by: Andi Kleen <ak@xxxxxxxxxxxxxxx> Signed-off-by: Len Brown <len.brown@xxxxxxxxx> commit a1a8d334f9e8c89a15bba8f34e443a37c29079c3 Author: Lin Ming <ming.m.lin@xxxxxxxxx> Date: Thu Jul 31 23:02:28 2008 +0200 Delete an unwanted return statement at evgpe.c Len's tree branch release-2.6.27, found an unwanted return statement at evgpe.c.

The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

CPUs declared as "Processor" should use the Local SAPIC's 'processor_id', and CPUs declared as "Device" should use the 'uid'. Note that for "Processor" declarations, even if a '_UID' child object exists, it has no bearing with respect to mapping Local SAPICs (see section 5.2.11.13 - Local SAPIC Structure; "Advanced Configuration and Power Interface Specification", Revision 3.0b). This patch changes the lsapic mapping logic to rely on the distinction of how the processor object was declared - the mapping can't just try both types of matches regardless of declaration type and rely on one failing as is currently being done.

Currently the two processor declaration types are conflated. This patch disambiguates the processor declaration's definition type enabling subsequent code to behave uniquely based explicitly on the declaration's type.

It was always set the same as CONFIG_ACPI, and it had no menu label, so there was no way to set it to anything other than "y". Per section 6.5.4 of the ACPI 3.0b specification, OSPM must make Embedded Controller operation regions, accessed via the Embedded Controllers described in ECDT, available before executing any control method. The ECDT table is optional, but if it is present, the above text means that the EC it describes is a required part of the ACPI subsystem, so CONFIG_ACPI_EC=n wouldn't make sense.

For all the GPEs and Fixed Events, 1. ACPI_EVENT_FLAG_HANDLE is cleared, it's an "invalid" ACPI event. 2. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_DISABLE are set, it's "disabled". 3. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_ENABLE are set, it's "enabled". 4. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_WAKE_ENABLE are set, it's "wake_enabled".

For example: If the power resource defined in _PR0 object is turned off, it indicates that the FAN device is in off state(the ACPI state is in D3 state). Maybe the device is already in D3 state and expected to be transited to D3 state. As there is no _PR3 object, the power transition can't be finished and it will be switched to the Unknown state. Maybe it is more reasonable that the strick check in power transistion is deleted. http://bugzilla.kernel.org/show_bug.cgi?id=9485 Signed-off-by: yakui.zhao@xxxxxxxxx Signed-off-by: Len Brown <len.brown@xxxxxxxxx> commit b1b57fbe9bb10d94682a975456de7a727d1dbc84 Author: Zhao Yakui <yakui.zhao@xxxxxxxxx> Date: Mon Oct 27 16:04:53 2008 +0800 ACPI: fix de-reference bug in power resource driver change state to *state in the function of acpi_power_get_state() Signed-off-by: yakui.zhao@xxxxxxxxx Signed-off-by: Len Brown <len.brown@xxxxxxxxx> commit bd2b064ecd5504a9e9eeaa5742b9f8bcc6d27637 Author: Matthew Garrett <mjg59@xxxxxxxxxxxxx> Date: Thu Oct 16 17:29:10 2008 -0400 sony-laptop: Ignore missing _DIS method on pic device At least the Vaio VGN-Z540N doesn't have this method, so let's not fail to suspend just because it doesn't exist.
