linux-toradex.git/include/acpi/pdc_intel.h, branch v2.6.16-rc4 Linux kernel for Apalis and Colibri modules [ACPI] Avoid BIOS inflicted crashes by evaluating _PDC only once 2005-12-01T06:30:35+00:00 Venkatesh Pallipadi venkatesh.pallipadi@intel.com 2005-10-23T20:31:00+00:00 05131ecc99ea9da7f45ba3058fe8a2c1d0ceeab8 Linux invokes the AML _PDC method (Processor Driver Capabilities) to tell the BIOS what features it can handle. While the ACPI spec says nothing about the OS invoking _PDC multiple times, doing so with changing bits seems to hopelessly confuse the BIOS on multiple platforms up to and including crashing the system. Factor out the _PDC invocation so Linux invokes it only once. http://bugzilla.kernel.org/show_bug.cgi?id=5483 Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com> 
Linux invokes the AML _PDC method (Processor Driver Capabilities)
to tell the BIOS what features it can handle.  While the ACPI
spec says nothing about the OS invoking _PDC multiple times,
doing so with changing bits seems to hopelessly confuse the BIOS
on multiple platforms up to and including crashing the system.

Factor out the _PDC invocation so Linux invokes it only once.
