OvmfPkg: introduce 4MB flash image (mainly) for Windows HCK The "Confirm64KilobytesOfUnauthenticatedVariableStorage" test case of the Secure Boot Logo Test ("Microsoft.UefiSecureBootLogo.Tests") suite in the Microsoft Hardware Certification Kit expects to be able to populate the variable store up to roughly 64 KB, with a series of 1 KB sized, unauthenticated variables. OVMF's current live varstore area is too small for this: 56 KB. Introduce the FD_SIZE_4MB build macro (equivalently, FD_SIZE_IN_KB=4096), which - enlarges the full flash image to 4MB -- QEMU supports up to 8MB, see FLASH_MAP_BASE_MIN in "hw/i386/pc_sysfw.c" --, - inside that, grows the varstore area / pflash chip to 528 KB, and within it, the live area from 56 KB to 256 KB. Importantly, a firmware binary built with -D FD_SIZE_4MB will *not* be compatible with a variable store that originates from a variable store template built *without* -D FD_SIZE_4MB. This is the reason for the large increase, as every such change breaks compatibility between a new firmware binary and old varstore files. Enlarging the varstore does not impact the performance of normal operations, as we keep the varstore block size 4KB. The performance of reclaim is affected, but that is expected (since reclaim has to rework the full live area). And, reclaim occurs proportionally less frequently. While at it, the FVMAIN_COMPACT volume (with the compressed FFS file in it) is also enlarged significantly, so that we have plenty of room for future DXEFV (and perhaps PEIFV) increments -- DXEFV has been growing steadily, and that increase shows through compression too. Right now the PEIFV and DXEFV volumes need no resizing. Here's a summary: Description Compression type Size [KB] ------------------------- ----------------- ---------------------- Non-volatile data storage open-coded binary 128 -> 528 ( +400) data Variable store 56 -> 256 ( +200) Event log 4 -> 4 ( +0) Working block 4 -> 4 ( +0) Spare area 64 -> 264 ( +200) FVMAIN_COMPACT uncompressed 1712 -> 3360 (+1648) FV FFS file LZMA compressed PEIFV uncompressed 896 -> 896 ( +0) individual PEI uncompressed modules DXEFV uncompressed 10240 -> 10240 ( +0) individual DXE uncompressed modules SECFV uncompressed 208 -> 208 ( +0) SEC driver reset vector code For now, the 2MB flash image remains the default.

OvmfPkg: Sec: assert the build-time calculated end of the scratch buffer The DecompressMemFvs() function in "OvmfPkg/Sec/SecMain.c" uses more memory, temporarily, than what PEIFV and DXEFV will ultimately need. First, it uses an output buffer for decompression, second, the decompression itself needs a scratch buffer (and this scratch buffer is the highest area that SEC uses). DecompressMemFvs() used to be called on normal boots only (ie. not on S3 resume), which is why the decompression output buffer and the scratch buffer were allowed to scribble over RAM. However, we'll soon start to worry during S3 resume that the runtime OS might tamper with the pre-decompressed PEIFV, and we'll decompress the firmware volumes on S3 resume too, from pristine flash. For this we'll need to know the end of the scratch buffer in advance, so we can prepare a non-malicious OS for it. Calculate the end of the scratch buffer statically in the FDF files, and assert in DecompressMemFvs() that the runtime decompression will match it.
