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.

2021-10-26cpu/x86/Kconfig.debug_cpu: drop HAVE_DISPLAY_MTRRS optionFelix Held
Since all x86 CPUs in tree have MTRR support, there is no need to guard the DISPLAY_MTRRS option with HAVE_DISPLAY_MTRRS. Also all x86 CPUs/SoCs have a display_mtrrs call at least somewhere in their code, so selecting the DISPLAY_MTRRS option will always have an effect. All SoCs that don't select RESET_VECTOR_IN_RAM have the postcar stage where it gets called. The two AMD SoCs that select RESET_VECTOR_IN_RAM use the FSP2 driver which contains plenty of display_mtrrs calls.

2021-10-26cpu/x86: Introduce and use `CPU_X86_LAPIC`Felix Held
With using a Kconfig option to add the x86 LAPIC support code to the build, there's no need for adding the corresponding directory to subdirs in the CPU/SoC Makefile. Comparing which CPU/SoC Makefiles added (cpu/)x86/mtrr and (cpu/)x86/lapic before this and the corresponding MTRR code selection patch and having verified that all platforms added the MTRR code on that patch shows that soc/example/min86 and soc/intel/quark are the only platforms that don't end up selecting the LAPIC code. So for now the default value of CPU_X86_LAPIC is chosen as y which gets overridden to n in the Kconfig of the two SoCs mentioned above.

2021-10-25cpu,soc/x86: always include cpu/x86/mtrr on x86 CPUs/SoCsFelix Held
All x86-based CPUs and SoCs in the coreboot tree end up including the Makefile in cpu/x86/mtrr, so include this directly in the Makefile in cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is selected be default could be added and the new CPU/SoC without MTRR support can override this option that then will be used in the Makefile to guard adding the Makefile from the cpu/x86/mtrr sub-directory. In cpu/intel all models except model 2065X and 206AX are selcted by a socket and rely on the socket's Makefile.inc to add x86/mtrr to the subdirs, so those models don't add x86/mtrr themselves. The Intel Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the subdirs. The Intel Xeon SP SoC directory contains two sub-folders for different versions or generations which both add x86/mtrr to the subdirs in their Makefiles.

2021-10-22cpu/x86/mp_init: move printing of failure message into mp_init_with_smmFelix Held
Each CPU/SoC checks the return value of the mp_init_with_smm and prints the same error message if it wasn't successful, so move this check and printk to mp_init_with_smm. For this the original mp_init_with_smm function gets renamed to do_mp_init_with_smm and a new mp_init_with_smm function is created which then calls do_mp_init_with_smm, prints the error if it didn't return CB_SUCCESS and passes the return value of do_mp_init_with_smm to its caller. Since no CPU/SoC code handles a mp_init_with_smm failure apart from printing a message, also add a comment at the mp_init_with_smm call sites that the code might want to handle a failure.

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.

2021-03-19cpu/intel/fit: Add the FIT table as a separate CBFS fileArthur Heymans
With CBnT a digest needs to be made of the IBB, Initial BootBlock, in this case the bootblock. After that a pointer to the BPM, Boot Policy Manifest, containing the IBB digest needs to be added to the FIT table. If the fit table is inside the IBB, updating it with a pointer to the BPM, would make the digest invalid. The proper solution is to move the FIT table out of the bootblock. The FIT table itself does not need to be covered by the digest as it just contains pointers to structures that can by verified by the hardware itself, such as microcode and ACMs (Authenticated Code Modules).

2021-03-12cpu/intel/microcode: Fix caching logic in intel_microcode_findFurquan Shaikh
CB:49896 added support in `intel_microcode_find()` to cache the found microcode for faster subsequent accesses. This works okay when the function succeeds in finding the microcode on BSP. However, if for any reason, `cpu_microcode_blob.bin` does not contain a valid microcode for the given processor, then the logic ends up attempting to find microcode again and again every time it is called (because `ucode_updates` is set to NULL on failed find, thus retriggering the whole find sequence every time). This leads to a weird race condition when multiple APs are running in parallel and executing this function. A snippet of the issues observed in the scenario described above: ``` ... microcode: Update skipped, already up-to-date ... Microcode header corrupted! ... ``` 1. AP reports that microcode update is being skipped since the current version matches the version in CBFS (even though there is no matching microcode update in CBFS). 2. AP reports microcode header is corrupted because it thinks that the data size reported in the microcode is larger than the file read from CBFS. Above issues occur because each time an AP calls `intel_microcode_find()`, it might end up seeing some intermittent state of `ucode_updates` and taking incorrect action. This change fixes this race condition by separating the logic for finding microcode into an internal function `find_cbfs_microcode()` and maintaining the caching logic in `intel_microcode_find()` using a boolean flag `microcode_checked`. BUG=b:182232187 TEST=Verified that `intel_microcode_find()` no longer makes repeated attempts to find microcode from CBFS if it failed the first time.

2021-01-26cpu/intel/common/fsb.c: Add Broadwell CPUID modelsAngel Pons
Like Haswell, Broadwell has a "FSB" speed of 100 MHz. Add the IDs for both the traditional and ULT variants of Broadwell, because the CPU driver for Haswell already contains CPUIDs for both Broadwell types. Without this patch, Broadwell CPUs would hang when trying to print the first console log message, but only if flashconsole was not enabled. This was missed in commit f542b7bcef (cpu/intel/haswell: Add Broadwell CPUIDs and microcode) and went unnoticed until now because the tests were done with flashconsole enabled, which somehow boots properly even though the console time tracking would not work (depends on TSC). Tested on out-of-tree Acer E5-573, fixes booting without flashconsole.

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.
