2015-07-26MdeModulePkg PiSmmCore: Remove a hidden assumption of SMRAM reservationStar Zeng
that assumes the SMRAM reserved range is only at the end of the SMRAM descriptor. // // This range has reserved area, calculate the left free size // gSmmCorePrivate->SmramRanges[Index].PhysicalSize = SmramResRegion->SmramReservedStart - gSmmCorePrivate->SmramRanges[Index].CpuStart; Imagine the following scenario where we just reserve the first page of the SMRAM range: SMRAM Descriptor: Start: 0x80000000 Size: 0x02000000 Reserved Range: Start: 0x80000000 Size: 0x00001000 In this case the adjustment to the SMRAM range size yields zero: ReservedStart - SMRAM Start is 0x80000000 - 0x80000000 = 0. So even though most of the range is still free the IPL code decides its unusable. The problem comes from the email thread: [edk2] PiSmmIpl SMRAM Reservation Logic. http://thread.gmane.org/gmane.comp.bios.tianocore.devel/15268 Also to follow the idea in the email thread, the patch is to 1. Keep only one copy of full SMRAM ranges in gSmmCorePrivate->SmramRanges, split record for SmmConfiguration->SmramReservedRegions and SMM Core that will be marked to be EFI_ALLOCATED in gSmmCorePrivate->SmramRanges. 2. Handle SmmConfiguration->SmramReservedRegions at beginning of, at end of, in the middle of, or cross multiple SmramRanges.

2015-06-19MdeModulePkg: Enhance the comments for PiSmmCoreMemoryAllocationLib instance.Qiu Shumin
Per PI spec all allocation of SMRAM should use EfiRuntimeServicesCode or EfiRuntimeServicesData. So SMM instance use EfiRuntimeServicesCode as the default memory allocation type instead of EfiBootServicesData. This patch clarify this usage in comments.

from FullSmramRanges and FullSmramRangeCount in SmmCorePrivate by Constructor. It can avoid potential first call to FreePool() -> BufferInSmram() -> if (mSmramRanges == NULL) { GetSmramRanges();} -> gBS->LocateProtocol() at boottime with >= TPL_NOTIFY or after ReadyToLock or at OS runtime.

2. Add MODULE_UNI_FILE file that contains the localized Abstract and Description of a module. a. Addresses an information gap between INF files and the UEFI Distribution Packaging Specification XML schema b. There will be an associated update to UPT in BaseTools to consume MODULE_UNI_FILE and associated UNI file during UDP creation that performs the INF -> XML conversion. c. There will be an associated update to UPT in BaseTools to produce MODULE_UNI_FILE and associated UNI file during UDP installation that performs the XML -> INF conversion. 3. Add Module Extra UNI file that provides the localized Name of a module. a. [UserExtensions.TianoCore."ExtraFiles"] provides an easy method for a module to specify extra files not listed in [Sources] or [Binaries] sections to be added to a UDP without having to list the files in the UPT package information data file. b. There will be an associated update to UPT in BaseTools to package up files listed in [UserExtensions.TianoCore."ExtraFiles"] during UDP creation. c. UNI file contains localized name of a module to go along with the localized Abstract and Description from the MODULE_UNI_FILE.
