linux-toradex.git/arch/x86/kernel/acpi, branch v3.0.63 Linux kernel for Apalis and Colibri modules ACPI: Remove one board specific WARN when ignoring timer overriding 2012-07-16T15:47:52+00:00 Feng Tang feng.tang@intel.com 2012-06-04T07:00:05+00:00 05e3b20ed735718a6fecbeb1f1234c15628145f0 commit 7f68b4c2e158019c2ec494b5cfbd9c83b4e5b253 upstream. Current WARN msg is only for the ati_ixp4x0 board, while this function is used by mulitple platforms. So this one board specific warning is not appropriate any more.

ACPI: Make acpi_skip_timer_override cover all source_irq==0 cases 2012-07-16T15:47:52+00:00 Feng Tang feng.tang@intel.com 2012-06-04T07:00:04+00:00 62aae691aaecc2695294cfdc6719f7bd5bbcd9c6 commit ae10ccdc3093486f8c2369d227583f9d79f628e5 upstream. Currently when acpi_skip_timer_override is set, it only cover the (source_irq == 0 && global_irq == 2) cases. While there is also platform which need use this option and its global_irq is not 2. This patch will extend acpi_skip_timer_override to cover all timer overriding cases as long as the source irq is 0. This is the first part of a fix to kernel bug bugzilla 40002: "IRQ 0 assigned to VGA" https://bugzilla.kernel.org/show_bug.cgi?id=40002 Reported-and-tested-by: Szymon Kowalczyk <fazerxlo@o2.pl> Signed-off-by: Feng Tang <feng.tang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

ACPI: Add a quirk for "AMILO PRO V2030" to ignore the timer overriding 2012-07-16T15:47:40+00:00 Feng Tang feng.tang@intel.com 2012-06-04T07:00:06+00:00 13c3a2a53f2b78e57d595c46de9aa1aea2f9af19 commit f6b54f083cc66cf9b11d2120d8df3c2ad4e0836d upstream. This is the 2nd part of fix for kernel bugzilla 40002: "IRQ 0 assigned to VGA" https://bugzilla.kernel.org/show_bug.cgi?id=40002 The root cause is the buggy FW, whose ACPI tables assign the GSI 16 to 2 irqs 0 and 16(VGA), and the VGA is the right owner of GSI 16. So add a quirk to ignore the irq0 overriding GSI 16 for the FUJITSU SIEMENS AMILO PRO V2030 platform will solve this issue.

x86, suspend: Restore MISC_ENABLE MSR in realmode wakeup 2011-07-07T03:09:34+00:00 Kees Cook kees.cook@canonical.com 2011-07-07T01:10:34+00:00 7a3136666bc0f0419f7aaa7b1fabb4b0e0a7fb76 Some BIOSes will reset the Intel MISC_ENABLE MSR (specifically the XD_DISABLE bit) when resuming from S3, which can interact poorly with ebba638ae723d8a8fc2f7abce5ec18b688b791d7. In 32bit PAE mode, this can lead to a fault when EFER is restored by the kernel wakeup routines, due to it setting the NX bit for a CPU that (thanks to the BIOS reset) now incorrectly thinks it lacks the NX feature. (64bit is not affected because it uses a common CPU bring-up that specifically handles the XD_DISABLE bit.) The need for MISC_ENABLE being restored so early is specific to the S3 resume path. Normally, MISC_ENABLE is saved in save_processor_state(), but this happens after the resume header is created, so just reproduce the logic here. (acpi_suspend_lowlevel() creates the header, calls do_suspend_lowlevel, which calls save_processor_state(), so the saved processor context isn't available during resume header creation.)
