2023-03-13cpu/x86/cache: CLFLUSH programs to memory before runningArthur Heymans
When cbmem is initialized in romstage and postcar placed in the stage cache + cbmem where it is run, the assumption is made that these 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's to make that UC. TESTED on asus/p5ql-em, up/squared on both regular and S3 resume bootpath. Sometimes there are minimal performance improvements when cbmem is cached (few ms).

2021-10-26src/cpu: drop CPU_X86_CACHE_HELPER and x86_enable_cache wrapper functionFelix Held
Selecting CPU_X86_CACHE_HELPER only added the x86_enable_cache wrapper function around enable_cache which additionally wrote a POST code to port 0x80 and printed a message to the console. This function was only called during multi-processor initialization in ramstage via the init function pointer in the CPU's device operations struct and was run on all cores, so the message on the console was printed once per CPU core. This patch replaces all x86_enable_cache calls by calls to enable_cache and removes the wrapper function and the Kconfig symbol CPU_X86_CACHE_HELPER which was used to only add this when the corresponding CPUs used the x86_enable_cache wrapper function.

2010-09-30Rename build system variables to be more intuitive, andPatrick Georgi
at the same time let the user specify sources instead of object files: - objs becomes ramstage-srcs - initobjs becomes romstage-srcs - driver becomes driver-srcs - smmobj becomes smm-srcs The user servicable parts are named accordingly: ramstage-y, romstage-y, driver-y, smm-y Also, the object file names are properly renamed now, using .ramstage.o, .romstage.o, .driver.o, .smm.o suffixes consistently. Remove stubbed out via/epia-m700 dsdt/ssdt files - they didn't easily fit in the build system and aren't useful anyway.
