2020-11-04soc/intel/skl,acpi/acpigen: convert global CPPC package to local oneMichael Niewöhner
Move the global CPPC package \GCPC to the first logical core CP00 and adapt the reference in the other cores. This is cleaner and avoids confusion.

2020-10-28soc/intel: deduplicate ACPI timer emulationMichael Niewöhner
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>

2020-09-21soc/intel/skylake: acpi: drop HWP's dependency on EISTMichael Niewöhner
Enhanced Intel SpeedStep Technology (EIST) and Intel Speed Shift Technology (ISST) - also know as HWP - are two independent mechanisms for controlling voltage and frequency based on performance hints. When HWP is enabled, it overrides the software-based EIST. It does not depend on EIST, though, but can be enabled on its own. Break up that currently existing dependency in ACPI generation code. It was tested that HWP can be enabled and gets used by the Linux pstate cpufreq driver. With HWP disabled, the frequency does not decrease, even not in powersave mode. After enabling HWP the frequency changed in relation to the current workload.

2020-09-14soc/intel/common/cpu: Update COS mask calculation for NEM enhanced modeAamir Bohra
Update the COS mask calculation to accomodate the RW data as per SoC configuration. Currently only one way is allocated for RW data and configured for non-eviction. For earlier platform this served fine, and could accomodate a RW data up to 256Kb. Starting TGL and JSL, the DCACHE_RAM_SIZE is configured for 512Kb, which cannot be mapped to a single way. Hence update the number of ways to be configured for non- eviction as per total LLC size. The total LLC size/ number of ways gives the way size. DCACHE_RAM_SIZE/ way size gives the number of ways that need to be configured for non- eviction, instead of harcoding it to 1. TGL uses MSR IA32_CR_SF_QOS_MASK_1(0x1891) and IA32_CR_SF_QOS_MASK_2(0x1892) as COS mask selection register and hence needs to be progarmmed accordingly. Also JSL and TGL platforms the COS mask selection is mapped to bit 32:33 of MSR IA32_PQR_ASSOC(0xC8F) and need to be updated in edx(maps 63:32) before MSR write instead of eax(maps 31:0). This implementation corrects that as well. BUG=b:149273819 TEST= Boot waddledoo(JSL), hatch(CML), Volteer(TGL)with NEM enhanced CAR configuration.
