2021-02-01cpu/x86/mp_init.c: Print out the microcode revision of APsArthur Heymans

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.

2020-11-09cpu/x86/smm: Add a common save state handlingArthur Heymans
Currently coreboot has limited use for the SMM save state. Typically the only thing needed is to get or set a few registers and to know which CPU triggered the SMI (typically via an IO write). Abstracting away different SMM save states would allow to put some SMM functionality like the SMMSTORE entry in common places. To save place platforms can select different SMM save sate ops that should be implemented. For instance AMD platforms don't need Intel SMM save state handling. Some platforms can encounter CPUs with different save states, which the code then handles at runtime by comparing the SMM save state revision which is located at the same offset for all SMM save state types.

2020-10-30cpu/x86: increase timeout for CPUs to check in after 2nd SIPIJonathan Zhang
Increase timeout for CPUs to check in after 2nd SIPI completion from 10ms to 100ms. Update logging level for mp init failure cases from BIOS_DEBUG to BIOS_ERR. Without this patch, "mp initialization failure" happens on some reboots on DeltaLake server. As consequence, not all 52 cpus come up in Linux: [root@localhost ~]# lscpu ... CPU(s): 40 Also following Hardware Errors are seen: [ 4.365762] mce: [Hardware Error]: Machine check events logged [ 4.366565] mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 9: ee2000000003110a [ 4.367561] mce: [Hardware Error]: TSC 0 ADDR fe9e0000 MISC 228aa040101086 [ 4.368563] mce: [Hardware Error]: PROCESSOR 0:5065b TIME 948438164 SOCKET 0 APIC 0 microcode 700001d With this patch, no such failure is observed with 370 reboots.

2020-10-20cpu/x86/mtrr: add support for address space higher than 16TiBJonathan Zhang
On DeltaLake server, there are following entry in MTRR address space: 0x0000201000000000 - 0x0000201000400000 size 0x00400000 type 0 In this case, the base address (with 4k granularity) cannot be held in uint32_t. This results incorrect MTRR register setup. As the consequence UEFI forum FWTS reports following critical error: Memory range 0x100000000 to 0x183fffffff (System RAM) has incorrect attribute Uncached. Change appropriate variables' data type from uint32_t to uint64_t. Add fls64() to find least significant bit set in a 64-bit word. Add fms64() to find most significant bit set in a 64-bit word.
