(The total size is 2 * PcdFlashNvStorageFtwSpareSize.) FaultTolerantWriteDxe in turn expects the block size to be a power of two. In the 4MB build of OVMF, PcdFlashNvStorageFtwSpareSize is 264KB, which is not a power of two. In order to equip EmuVariableFvbRuntimeDxe for this build, shrink the block size to 4KB (EFI_PAGE_SIZE), and grow the block count from 2 to EFI_SIZE_TO_PAGES(2 * PcdFlashNvStorageFtwSpareSize). The total size remains 2 * PcdFlashNvStorageFtwSpareSize --------------------------------- * EFI_PAGE_SIZE EFI_PAGE_SIZE Right now EmuVariableFvbRuntimeDxe open-codes the block count of 2 in various limit checks, so introduce a few new macros: - EMU_FVB_NUM_TOTAL_BLOCKS, for the LHS of the above product, - EMU_FVB_NUM_SPARE_BLOCKS for the half of that. Also rework the FVB protocol members to support an arbitrary count of blocks. Keep the invariant intact that the first half of the firmware volume hosts the variable store and the FTW working block, and that the second half maps the FTW spare area.
