* reverse CONFIG_ACPI_PROC_EVENT defaultHugh Dickins2007-08-27
| | | | | | | | | | | | | | | | Sigh. Again an ACPI assault on the Thinkpad's Fn+F4 to suspend to RAM. The default and text for CONFIG_THINKPAD_ACPI_INPUT_ENABLED were fixed in -rc3, but now commit 14e04fb34ffa82ee61ae69f98d8fca12d2e8e31c ("ACPI: Schedule /proc/acpi/event for removal") introduces the ACPI_PROC_EVENT config entry, and defaults it to 'n' to disable it again. Change default to y, and add comment to make it clearer that n is for future distros.

| * ACPI: work around duplicate name "VID" problem on T61Zhang Rui2007-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This can only fix the problem that more than one video bus device have the same AML name "VID". ie. the proc I/F for the second "VID" video bus device is located under /proc/acpi/video/VID1/... As this is really rare and the ACPI proc I/F is a legacy feature that we are planning to remove. We won't provide a generic solution for this problem.

| * | ACPI: don't duplicate input events on netlinkZhang Rui2007-08-23

However, some users of /proc/acpi/event are really input events, and they already report their events via the input layer. Introduce a new interface, acpi_bus_generate_netlink_event(), which is explicitly called by devices that want to repoprt events via netlink. This allows the input-like events to opt-out of generating netlink events. In summary: events that are sent via netlink: ac/battery/sbs thermal processor thinkpad_acpi dock/bay events that are sent via input layer: button video hotkey thinkpad_acpi hotkey asus_acpi/asus-laptop hotkey sonypi/sonylaptop Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

However, several systems have failed because the XSDT contains NULL entries -- while it is missing pointers to needed tables, such as SSDTs.

This allows the rq clock to work around TSC-stops-in-C2, TSC-gets-corrupted-in-C3 type of problems. ( Besides the scheduler's statistics this also benefits blktrace and printk-timestamps as well. ) Furthermore, the precise before-C2/C3-sleep and after-C2/C3-wakeup callbacks allow the scheduler to get out the most of the period where the CPU has a reliable TSC. This results in slightly more precise task statistics. the ACPI bits were acked by Len. Signed-off-by: Ingo Molnar <mingo@elte.hu> Acked-by: Len Brown <len.brown@intel.com>
