2011-10-31Roll back the change on GetMemorySpaceAttributeFromMtrrType()'s parameter ↵vanjeff
type, from MTRR_MEMORY_CACHE_TYPE to UINT8 since MtrrAttributes may be the value not belongs to MTRR_MEMORY_CACHE_TYPE. Signed-off-by: vanjeff git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12609 6f19259b-4bc3-4df7-8a09-765794883524
2011-10-281. Introduce the API MtrrGetDefaultMemoryType () in Mtrr Library.vanjeff
2. Invoke MtrrGetDefaultMemoryType() to get the default memory type instead of the hard code value in module. 3. Add go though for UC attributes. Signed-off-by: vanjeff Reviewed-by: rsun3 git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12587 6f19259b-4bc3-4df7-8a09-765794883524
2011-06-16UefiCpuPkg/CpuDxe: Put CPU to sleep during Idle eventsjljusten
When the MdeModulePkg gCoreEventIdleGuid event is signaled, CpuSleep is called. This will cause the CPU to sleep until the next interrupt occurs.

2010-10-22UefiCpuPkg CpuDxe: Fix bug with CPU Arch RegisterInterruptHandlerjljusten
The change in r10765 introduced an issue where inherited interrupt handlers would override the driver's RegisterInterruptHandler functionality. DUET installs a IDT with 256 entries early in it's boot. Therefore, no interrupt handlers could be installed with DUET while using UefiCpuPkg/CpuDxe (instead of DuetPkg/CpuDxe). This change forces the IDT to be modified when RegisterInterruptHandler is called to ensure the UEFI handler will be installed properly. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10972 6f19259b-4bc3-4df7-8a09-765794883524
