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.

This also increases the loglevel when bailing out of SMM due to unsupported SMM save state revision from BIOS_DEBUG to BIOS_WARNING, given that the system likely still boots but won't have a functioning smihandler.

msr_set_bit can only set single bits in MSRs and causes mixing of bit positions and bitmasks in the MSR header files. Thus, replace the helper by versions which can unset and set whole MSR bitmasks, just like the "and-or"-helper, but in the way commit 64a6b6c was done (inversion done in the helper). This helps keeping the MSR macros unified in bitmask style. In sum, the three helpers msr_set, msr_unset and msr_unset_and_set get added. The few uses of msr_set_bit have been replaced by the new version, while the used macros have been converted accordingly.

2020-09-12cpu/intel/model_1067x: enable PECIMichael Büchler
This is required for Super I/Os to be able to read the CPU temperature through PECI. On 45nm Core 2 CPUs (Wolfdale, Yorkfield) it is not enabled by default. This is probably related to erratum AW67 "Enabling PECI via the PECI_CTL MSR incorrectly writes CPUID_FEATURE_MASK1 MSR". The suggested workaround is "Do not initialize PECI before processor update is loaded". Since coreboot performs microcode updates before running this code it should not cause any trouble. It was tested on a Core 2 Duo E8400, stepping E0. PECI is already enabled by default on older (65nm) CPUs. Tested: Pentium Dual-Core E2160.

2020-08-15cpu/x86/smm: Introduce SMM module loader version 2Rocky Phagura
Xeon-SP Skylake Scalable Processor can have 36 CPU threads (18 cores). Current coreboot SMM is unable to handle more than ~32 CPU threads. This patch introduces a version 2 of the SMM module loader which addresses this problem. Having two versions of the SMM module loader prevents any issues to current projects. Future Xeon-SP products will be using this version of the SMM loader. Subsequent patches will enable board specific functionality for Xeon-SP. The reason for moving to version 2 is the state save area begins to encroach upon the SMI handling code when more than 32 CPU threads are in the system. This can cause system hangs, reboots, etc. The second change is related to staggered entry points with simple near jumps. In the current loader, near jumps will not work because the CPU is jumping within the same code segment. In version 2, "far" address jumps are necessary therefore protected mode must be enabled first. The SMM layout and how the CPUs are staggered are documented in the code. By making the modifications above, this allows the smm module loader to expand easily as more CPU threads are added. TEST=build for Tiogapass platform under OCP mainboard. Enable the following in Kconfig. select CPU_INTEL_COMMON_SMM select SOC_INTEL_COMMON_BLOCK_SMM select SMM_TSEG select HAVE_SMI_HANDLER select ACPI_INTEL_HARDWARE_SLEEP_VALUES Debug console will show all 36 cores relocated. Further tested by generating SMI's to port 0xb2 using XDP/ITP HW debugger and ensured all cores entering and exiting SMM properly. In addition, booted to Linux 5.4 kernel and observed no issues during mp init.

NOTE: This commit does NOT introduce a new security model. It uses the same page tables as the remaining firmware does.
