| | | | | | | * | | | | | | | | | firewire: unnecessary BM delay after generation rolloverStefan Richter2009-01-20

If there happened bus resets without self ID complete events in the meantime, or self ID complete events with invalid selfIDs, the topology comparison could identify nodes wrongly, or more likely just corrupt kernel memory or panic right away. We now discard all nodes of the old topology and treat all current nodes as new ones if the current self ID generation is not the previous one plus 1.

This array is currently statically defined (see ./drivers/acpi/tables.c). When there are more table entries than can be held in the 'initial_tables[]' array, the message "Truncating N table entries!" is output. As currently implemented, this message will always erroneously calculate N as 0. This patch fixes the calculation that determines how many table entries will be missing (truncated). This modification may be used under either the GPL or the BSD-style license used for Intel ACPI CA code.

This can also be seen in commit 8b59560a3baf2e7c24e0fb92ea5d09eca92805db (ACPI: dock: avoid check _STA method). If an undock is processed, the dock driver sends a uevent and userspace might read the show_docked property in sysfs. This causes an evaluation of _STA of the particular device which causes the dock driver to immediately dock again. In any case, evaluation of _STA (show_docked) does not necessarily mean that we are docked, so check with the internal device structure. http://bugzilla.kernel.org/show_bug.cgi?id=12360 Signed-off-by: Holger Macht <hmacht@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>

This is contrary to the erroneous wording the ACPI 2.0, 3.0 specifications that suggests that BM_RLD is an indicator rather than a control bit. ACPI 1.0's correct wording should be restored in ACPI 4.0: http://www.acpica.org/bugzilla/show_bug.cgi?id=689 But the kernel should not have to clear BM_RLD when entering a non C3-type state just to set it again when entering a C3-type C-state. We should be able to set BM_RLD at boot time and leave it alone -- removing the overhead of accessing this IO register from the idle entry path. Signed-off-by: Len Brown <len.brown@intel.com>

The fields in PM1x_STS are single bits only, there are no multi-bit fields. So it is not necessary to lock PM1x_STS reads against writes because it is impossible to read an intermediate value of a single bit. It will either be 0 or 1, even if a write is in progress during the read. Reads are asynchronous to writes no matter if a lock is used or not. Signed-off-by: Len Brown <len.brown@intel.com>

The first is the brightness when full power is connected to the box(It means that the AC adapter is plugged). The second is the brightness level when the box is on battery. If the first two elements are still used while finding the next brightness level, it will fall back to the lowest level when keeping on pressing hotkey. (On some boxes the brightness will be changed twice when hotkey is pressed once. One is in the ACPI video driver. The other is changed by sys I/F. In the ACPI video driver the first two elements will be used while changing the brightness. But the first two elements is skipped while using sys I/F. In such case there exists the inconsistency). So he first two elements had better be skipped while showing the available brightness or finding the next brightness level. http://bugzilla.kernel.org/show_bug.cgi?id=12450 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

For both kinds the tool: http://www.draisberghof.de/usb_modeswitch/ should work. Note that the various versions of the device have the same ProductId, VendorId, and bcdDevice number, so we cannot have the entry for some and not others.

This patch relocates the pieces from under #ifdef CONFIG_COMPAT into compat_ioctl with no other changes except one new whitespace.
