2021-05-05src/cpu/x86/smm: remove debug message; not thread safeRocky Phagura
This patch removes a call to console_init() and debug print message since the code is not thread safe. This prevents system hangs (soft hangs) while in SMM if user drops in a new SOC with more cores or another socket or as a result of bad configuration. Console is already initialized after the lock has been acquired so this does not affect any other functionality. Tested on DeltaLake mainboard with SMM enabled and 52 CPU threads.

2021-04-29cpu/x86/mtrr: Use a Kconfig for reserving MTRRs for OSTim Wawrzynczak
Some platforms which have large amounts of RAM and also write-combining regions may decide to drop the WC regions in favor of the default when preserving MTRRs for the OS. From a data safety perspective, this is safe to do, but if, say, the graphics framebuffer is the region that is changed from WC to UC/WB, then the performance of writing to the framebuffer will decrease dramatically. Modern OSes typically use Page Attribute Tables (PAT) to determine the cacheability on a page level and usually do not touch the MTRRs. Thus, it is believed to be safe to stop reserving MTRRs for the OS, in general; PentiumII is the exception here in that OSes that still support that may still require MTRRs to be available. In any case, if the OS wants to reprogram all of the MTRRs, it is of course still free to do so (after consulting the e820 table). BUG=b:185452338 TEST=Verify MTRR programming on a brya (where `sa_add_dram_resources` was faked to think it had 32 GiB of DRAM installed) and variable MTRR map includes a WC entry for the framebuffer (and all the RAM): MTRR: default type WB/UC MTRR counts: 13/9.

2021-01-15cpu/x86/mpinit: Serialize microcode updates for HT threadsPatrick Rudolph
This change affects Intel CPUs only. As most platforms are doing uCode update using FIT, they aren't affected by this code either. Update microcode in MP-init using a single spinlock when running on a Hyper-Threading enabled CPU on pre FIT platforms. This will slow down the MP-init boot flow. Intel SDM and various BWGs specify to use a semaphore to update microcode on one thread per core on Hyper-Threading enabled CPUs. Due to this complex code would be necessary to determine the core #ID, initializing and picking the right semaphore out of CONFIG_MAX_CPUS / 2. Instead use the existing global spinlock already present in MPinit code. Assuming that only pre-FIT platforms with Hyper-Threading enabled and at most 8 threads will ever run into this condition, the boot delay is negligible. This change is a counterproposal to the previous published patch series being much more unsophisticated.
