2010-04-02Use on-demand paging for CpuSaveStates read/write. It was measured about ↵jgong5
200us for either read or write the PI CpuSaveStates to framework, ~400us in total on a platform with 80 CPUs with original for loop implementation. So with on-demand paging, if the framework SMI handler doesn’t read/write CpuSaveStates, ~400us will be saved. If the handler happens to use CpuSaveStates, there will be about 20us overhead for either read or write a page which contains 5 continuous CpuSaveStates. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10328 6f19259b-4bc3-4df7-8a09-765794883524
2010-03-26Security enhancement to SMM Base thunk drivers: Framework SMM drivers can't ↵rsun3

2010-03-19NumberOfCpus and SmmStartupThisAp field in Framework SMST should be updated ↵rsun3
per PI SMST at SMM runtime context. These two fields in PI SMST are not guaranteed to be valid at SMM initialization phase. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10285 6f19259b-4bc3-4df7-8a09-765794883524

2010-03-17Remove the implementation limitation in the SmmBaseHelper driver that it ↵rsun3
assumes the Framework SMM driver to be loaded has a copy in memory. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10258 6f19259b-4bc3-4df7-8a09-765794883524

2010-01-05Fix bugs in SmmBaseHelper driver.rsun3
1. Should use sizeof(EFI_SMM_CPU_SAVE_STATE) instead of sizeof (EFI_SMI_CPU_SAVE_STATE) to allocate buffer for CpuSaveState in Framework SMST; 2. The type of Width parameter for ReadSaveState() and WriteSaveState() functions of SMM CPU Protocol is UINTN instead of an enumeration type. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9678 6f19259b-4bc3-4df7-8a09-765794883524
2009-12-31Add 4 Framework/PI SMM thunk drivers. Combined use of these drivers can ↵rsun3
