2022-06-02soc/intel/common/cpu: Use SoC overrides to set CPU privilege levelSubrata Banik
This patch implements a SoC overrides to set CPU privilege level as the MSR is not consistent across platforms. For example: On APL/GLK/DNV, it's MSR 0x120 and CNL onwards it's MSR 0x151.

2022-02-05cpu/x86/lapic: Move LAPIC configuration to MP initKyösti Mälkki
Implementation for setup_lapic() did two things -- call enable_lapic() and virtual_wire_mode_init(). In PARALLEL_MP case enable_lapic() was redundant as it was already executed prior to initialize_cpu() call. For the !PARALLEL_MP case enable_lapic() is added to AP CPUs.

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.

The code for enabling ACPI timer emulation is the same for the SoCs SKL, CNL, ICL, TGL, JSL and EHL. Deduplicate it by moving it to common code. APL differs in not having the delay settings. However, the bits are marked as "spare" and BWG mentions there are no "reserved bit checks done". Thus, we can write them unconditionally without any effect. Note: The ACPI timer emulation can only be used by SoCs with microcode supporting CTC (Common Timer Copy) / ACPI timer emulation.

2020-10-26soc/intel: drop unneeded ISST configuration codeMichael Niewöhner
The code configuring ISST (Intel SpeedShift Technology) sets the ISST capability bits in CPUID.06H:EAX. It does *not* activate HWP (Hardware P-States), which shall be done by the OS only. Since the capability is enabled by default (opt-out), there is nothing to do for us in the enabled-case. Practically speaking, there is no value at all in disabling the capability, since one can configure the OS to not enable HWP if that is desired. The two other bits for EPP and HWP interrupt that were set by the code are not set anymore, too. It was tested, on three platforms so far (CML-U, KBL-H, SKL-U), that these are set as well by default in the MSRs reset value (0x1cc0). To reduce complexity and duplicated code without actual benefit, this code gets dropped. The remaining dt option will be dropped in CB:46462. Test: Linux on Supermicro X11SSM-F detects and enables HWP: [ 0.415017] intel_pstate: HWP enabled Change-Id: I952720cf1de78b00b1bf749f10e9c0acd6ecb6b7 Signed-off-by: Michael Niewöhner <foss@mniewoehner.de> Reviewed-on: https://review.coreboot.org/c/coreboot/+/46460 Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-by: Felix Singer <felixsinger@posteo.net> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

Some timeouts given were too small when serial console is enabled due to its spinlock making code runtime worse with every AP present. In addition we usually don't know how long specific code runs and how long ago it was sent to the APs.

2017-08-21soc/intel/skylake: Fix SGX init sequencePratik Prajapati
Configure core PRMRR first on all the cores and then follow the SGX init sequence. Second microcode load would run the MCHECK. To pass MCHECK, PRMRR on all cores needs to be configured first. Hence, PRMRR configuration would be called from soc_core_init while MP init for each core and then from soc_init_cpus, BSP would call sgx_configure for each core (including for itself). This code flow satisfies the MCHECK passing pre-conditions; and apparently this patch fixes the behavior of calling configure_sgx() “again” for BSP. (So removed the TODO comment also).

This patch implements SGX initialization steps in coreboot per Intel SGX BWG rev 2.0.8 for Kaby Lake SoC. If enabled on a Kabylake device, SoC capability and PRM (processor reserved memory) of desired size (needs to be configured through PrmrrSize) are provisioned for later software stack to use SGX (i.e., run SGX enclaves). One issue is still puzzling and needs to be addressed: by calling configure_sgx() in cpu_core_init() which is the per-thread function, SGX is always failing for thread 0 but is successful for other 3 threads. I had to call configure_sgx() again from soc_init_cpus() which is the BSP-only function to make it enable on the BSP. Another pending work is the implementation for the Owner Epoch update which shall be added later. BUG=chrome-os-partner:62438 BRANCH=NONE TEST=Tested on Eve, verified SGX activation is successful on all threads.

With recent change (a4b11e5c90: soc/intel/skylake: Perform CPU MP Init before FSP-S Init) to perform CPU MP init before FSP-S init, suspend resume is currently broken for all skylake/kabylake boards. All the skylake/kabylake boards store external stage cache in TSEG, which is relocated post MP-init. Thus, if FSP loading and initialization is done after MP-init, then ramstage is not able to: 1. Save FSP component in external stage cache during normal boot, and 2. Load FSP component from external stage cache during resume In order to fix this, ensure that FSP loading happens separately from FSP initialization. Add fsp_load callback for pre_mp_init which ensures that the required FSP component is loaded/saved from/to external stage cache.
