Revision 2205cbe8ecaf5f3ab911cef839c94d05ea5b0c76 authored by Alex Chiang on 19 January 2010, 23:55:41 UTC, committed by Len Brown on 20 January 2010, 04:43:47 UTC
Commit 78f1699 (ACPI: processor: call _PDC early) blindly walks the namespace and calls _PDC on every processor object it finds. This change may cause issues on platforms that declare dummy values for SSDTs on non-present processors (disabled in MADT). When we call _PDC and dynamically attempt to execute the AML Load() op on these dummy SSDTs, there's no telling what might happen. Rather than finding every platform that has bogus SSDTs, restrict early _PDC calls to platforms that are known to need early evaluation of _PDC. This is a minimal, temporary fix (given the context of the current release cycle). A real solution of checking the MADT for non-present processors will be written for the next merge window.
