* cpu/qemu-x86/car: Move long mode entry right before c entryPatrick Rudolph2020-09-291-0/+3
| | | | | | | | | | | | | | | This fixes non-emulation platforms as those are using 32bit code after the bootblock_crt0 entry, like setting up CAR and updating microcode, which isn't yet converted to support long mode. This is a noop for the only supported x86_64 platform and all x86_32 platforms.

* cpu/intel/206ax/acpi.c: Fix get_cores_per_packageEvgeny Zinoviev2020-09-281-14/+4
| | | | | | | | | | | | | | | | | | | | | | | Current implementation uses CPUID 0Bh function that returns the number of logical cores of requested level. The problem with this approach is that this value doesn't change when HyperThreading is disabled (it's in the Intel docs), so it breaks generate_cpu_entries(). - Use MSR 0x35 instead, which returns the correct number of logical processors with and without HT. - Rename the function to get_logical_cores_per_package, which is more accurate. Tested on ThinkPad X220 with and without HT. Related to CB:29669.

| | | | | | | | | | | | | | With MAX_CPUS==1, this has the effect of removing spinlock implementation. But since is_smp_boot() evaluates false and SMM uses separate smi_semaphore, there is no concurrency to protect against with a spinlock.

* cpu/intel/model_1067x: enable PECIMichael Büchler2020-09-121-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | 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. See commit edac28ce65e48d6b2a0a2421d046a4fe4b2bf589 for the same change on cpu/intel/model_6fx.

* cpu/x86/smm: Introduce SMM module loader version 2Rocky Phagura2020-08-154-8/+698
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Also, reword the associated comment, which seems to be unnecessarily vague: the hardcoded assumptions are inside the MRC.

* cpu/x86/smm: Add support for long modePatrick Rudolph2020-07-082-1/+129
| | | | | | | | | | | | | | | | | | | | | | | Enable long mode in SMM handler. x86_32 isn't affected by this change. As the rsm instruction used to leave SMM doesn't restore MSR registers, drop back to protected mode after running the smi_handler and restore IA32_EFER MSR (which enables long mode support) to previous value. NOTE: This commit does NOT introduce a new security model. It uses the same page tables as the remaining firmware does. This can be a security risk if someone is able to manipulate the page tables stored in ROM at runtime. USE FOR TESTING ONLY! Tested on Qemu Q35.
