Change in coreboot[master]: [WIP]cpu/x86/cache: CLFLUSH programs to memory before running
by Arthur Heymans (Code Review) 21 Oct '22

21 Oct '22

Arthur Heymans has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/37196 ) Change subject: [WIP]cpu/x86/cache: CLFLUSH programs to memory before running ...................................................................... [WIP]cpu/x86/cache: CLFLUSH programs to memory before running When cbmem is initialized in romstage and postcar placed in the stage cache + cbmem where it is run, the assumption is made that this are all in UC memory such that calling invd in postcar is ok. For performance reasons (e.g. postcar decompression) it is desirable to cache cbmem and the stage cache during romstage. Another reason is that AGESA sets up MTRR during romstage to cache all dram, which is currently worked around by using additional MTRR to make that UC. TODO be nice to reviewers and spit some parts off.
