* ArmPlatformPkg/PrePi: replace set/way cache ops with by-VA onesArd Biesheuvel2020-03-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cache maintenance operations by set/way are only intended to be used in the context of on/offlining a core, while it has been taken out of the coherency domain. Any use intended to ensure that the contents of the cache have made it to main memory is unreliable, since cacheline migration and non-architected system caches may cause these contents to linger elsewhere, without being visible in main memory once the MMU and caches are disabled. In KVM on Linux, there are horrid hacks in place to ensure that such set/way operations are trapped, and replaced with a single by-VA clean/invalidate of the entire guest VA space once the MMU state changes, which can be costly, and is unnecessary if we manage the caches a bit more carefully, and perform maintenance by virtual address only. So let's get rid of the call to ArmInvalidateDataCache () in the PrePeiCore startup code, and instead, invalidate the UEFI memory region by virtual address, which is the only memory region we will be touching with the caches and MMU both disabled and enabled. (This will lead to data corruption if data written with the MMU off is shadowed by clean, stale cachelines that stick around when the MMU is enabled again.)

Stacks & Pi memory regions were set below the firmware. On some platform, the UEFI firmware could be shadowed by the ROM firmware (case of the BeagleBoard) and in some cases the firmware is copied at the beginning of the system memory. With this new memory model, stack and Pi/DXE memory regions are set at the top of the system memory wherever the UEFI firmware is located in the memory map. Because DXE core does not support shadowed firmwares, the system memory covered by the UEFI firmware is marked as 'Non Present' to avoid to be overlapped by DXE allocations. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11992 6f19259b-4bc3-4df7-8a09-765794883524
