2014-03-04OvmfPkg/Sec: Don't decompress the FV on S3 resumeJordan Justen
Since we marked the FV at PcdOvmfPeiMemFvBase as ACPI NVS memory, we can use it on S3 resume. The FV at PcdOvmfDxeMemFvBase may have been overwritten by the OS, but we do not use it's contents on S3 resume.

2014-01-21OvmfPkg: Split MAINFV into a separate PEI and DXE FVsJordan Justen
By splitting the PEI and DXE phases into separate FVs, we can only reserve the PEI FV for ACPI S3 support. This should save about 7MB. Unfortunately, this all has to happen in a single commit. DEC: * Remove PcdOvmfMemFv(Base|Size) * Add PcdOvmfPeiMemFv(Base|Size) * Add PcdOvmfDxeMemFv(Base|Size) FDF: * Add new PEIFV. Move PEI modules here. * Remove MAINFV * Add PEIFV and DXEFV into FVMAIN_COMPACT - They are added as 2 sections of a file, and compressed together so they should retain good compression * PcdOvmf(Pei|Dxe)MemFv(Base|Size) are set SEC: * Find both the PEI and DXE FVs after decompression. - Copy them separately to their memory locations.

2014-01-21OvmfPkg/Sec: Add FindFfsSectionInstanceJordan Justen
This allow you to search for an 'instance' of a section within a series of FFS sections. For example, we will split the MAINFV into a PEI and DXE FV, and then compress those two FV's together within a FFS FV file. The DXE FV will appear as the second section of the file, and therefore we will search for it using an Instance=1 value.

2014-01-21OvmfPkg: Move SEC/PEI Temporary RAM from 0x70000 to 0x810000Jordan Justen
Note: The Temporary RAM memory size is being reduced from 64KB to 32KB. This still appears to be more than adequate for OVMF's early PEI phase. We will be adding another 32KB range of RAM just above this range for use on S3 resume. The range is declared as part of MEMFD, so it is easier to identify the memory range. We also now assign PCDs to the memory range. The PCDs are used to set the initial SEC/PEI stack in SEC's assembly code. The PCDs are also used in the SEC C code to setup the Temporary RAM PPI.

2014-01-21OvmfPkg X64 ResetVector: Move page tables from 512KB to 8MBJordan Justen
To help consolidate OVMF fixed memory uses, we declare this range in MEMFD and thereby move it to 8MB. We also now declare the table range in the FDF to set PCDs. This allows us to ASSERT that CR3 is set as expected in OVMF SEC. OvmfPkgIa32.fdf and OvmfPkgIa32X64.fdf are updated simply for consistency.

2013-07-18OvmfPkg/Sec: Build identity mapped pages in RAM for X64Jordan Justen
This is based on MdeModulePkg/Core/DxeIplPeim/X64/VirtualMemory.c. Previously we would run using page tables built into the firmware device. If a flash memory is available, it is unsafe for the page tables to be stored in memory since the processor may try to write to the page table data structures. Additionally, when KVM ROM support is enabled for the firmware device, then PEI fails to boot when the page tables are in the firmware device.
