2023-01-31soc/intel/alderlake: Pick an unused and safer graphics address spaceJeremy Compostella
It turns out that the [0xfa000000-0xfaffffff] range conflicts with some North TraceHub address space ranges ([0xfad00000-0xfadfffff] and [0xfacfc000-0xfacfffff]). Experiments have established that this conflicting range results in an unpected PIPE A underrun issue reported by i915 and some visible flickers on the display during boot. The [0xf0000000-0xffffffff] range is a crowded memory space with resources statically assigned to some devices but also some ranges used at various point in the boot flow by the FSP. To not run into any other potential conflicts, we want to pick a unused memory space. But at this early stage of the boot, we do not have full knowledge of what memory space is going to be used by the FSP. As a result, we decided to pick the [0xaf000000-0xafffffff] range as: 1. It does not conflicting with any coreboot memory space usage 2. It is the address the FSP uses by default for GFX MMIO BAR0 and as such should not conflict with any FSP memory space usage.

2023-01-24soc/intel/adl: Option to create unified AP FW for UFS/Non-UFS SKUsSubrata Banik
This patch makes it easy for OEMs to keep a unified AP firmware image to boot different SKUs with UFS and non-UFS as boot media. With a unified image while booting on non-UFS SKU is exhibiting S0ix failure due to UFS remain enabled in the strap although FSP-S is making the UFS controller function disabled. The potential root cause of this behaviour is although the UFS controller is function disabled but MPHY clock is still in active state. A possible solution to this problem is to issue a warm reboot (if boot path is S5->S0 or G3->S0) after disabling the UFS and let PMC read the function disable state of the UFS for disabling the MPHY clock. Mainboard users with such board design where OEM would like to use an unified AP firmware to support both UFS and non-UFS sku booting might need to choose this config to allow disabling UFS while booting on the non-UFS SKU. Note: selection of this config would introduce an additional warm reset in cold-reset scenarios due to function disabling of the UFS controller.

2022-09-05soc/intel/alderlake: Remove dependency of FSP-S CpuMpPei ModuleSubrata Banik
This patch fixes a hidden issue present inside FSP-S while coreboot decides to skip performing MP initialization by overriding FSP-S UPDs as below: 1. CpuMpPpi ------> Passing `NULL` as coreboot assume FSP don't need to use coreboot wrapper for performing any operation over APs. 2. SkipMpInit -----> Set `1` to let FSP know that coreboot decided to skip FSP running CPU feature programming. Unfortunately, the assumption of coreboot is not aligned with FSP when it comes to the behaviour of `CpuMpPpi` UPD. FSP assumes ownership of the APs (Application Processors) upon passing `NULL` pointer to the `CpuMpPpi` FSP-S UPD. FSP-S creates its own infrastructure code after seeing the CpuMpPpi UPD is set to `NULL`. FSP requires the CpuMpPei module, file name `UefiCpuPkg/CpuMpPei/CpuMpPei.c`, function name `InitializeCpuMpWorker` to perform those additional initialization which is not relevant for the coreboot upon selecting the SkipMpInit UPD to 1 (a.k.a avoid running CPU feature programming on APs). Additionally, FSP-S binary size has increased by ~30KB (irrespective of being compressed) with the inclusion of the CpuMpPei module, which is eventually not meaningful for coreboot. Hence, this patch selects `MP_SERVICES_PPI_V2_NOOP` config unconditionally to ensure pass a valid pointer to the `CpuMpPpi` UPD and avoid APs getting hijacked by FSP while coreboot decides to set SkipMpInit UPD.

2022-03-10soc/intel/adl: Send EOP early in the boot sequenceMAULIK V VAGHELA
As part of boot time optimization, one of the culprit was CSE where response to End Of Post (EOP) command used to take ~60ms. Earlier patch was pushed to delay the EOP to reduce response time to ~5-7 ms. During this stage overall platform boot time was ~1.15 seconds. Once boot time was optimized to ~ 1 seconds, CSE EOP time again increased to ~80 ms since coreboot used to send EOP at the time where CSE was busy. This created some back and forth moving of sending EOP command function within coreboot sequence. Upon debugging using traces, it was found that coreboot used to send EOP late where CSE was busy loading other IP payload, so it might take more time to respond. In order to avoid delayed response, coreboot has to send EOP in stage when CSE is done with firmware init and it will be ready to serve EOP as soon as possible. This also aligns with previous flow where FSP used to send EOP once silicon init is done and coreboot used to rely on FSP to send this message. Moving EOP to earlier stage (From SoC) meets the requirement and CSE EOP time reduces from ~60 ms to ~20 ms on Brya board. Note that once SoC code sends EOP, coreboot common code won't send it again since common code already has check in case EOP is sent earlier.

Mainboards can use the `SOC_INTEL_ALDERLAKE_PCH_M` Kconfig option to specify which PCH type they use: select the option to choose PCH-M, do not select the option to choose PCH-P. While this works, it can be confusing once more PCH types are added. Introduce the `SOC_INTEL_ALDERLAKE_PCH_P` Kconfig option so that boards have to explicitly choose a PCH type. Also, use this option to restrict the PCH-P defaults for PCH-dependent settings to avoid unintended reuse of the PCH-P defaults when adding a new PCH type. To make sure only one PCH type is selected, add some preprocessor in `bootblock.h` to provoke a build-time error if this requirement is not met. Kconfig doesn't seem to have a mechanism to describe sets of mutually-exclusive bool options that allows said options to be selected (a `choice` block doesn't allow its elements to be selected). Finally, adapt the ADL boards accordingly.

Technically, it's not depending on the hardware but on the software (OS/payload), if the PM Timer is optional. OSes with ACPI >= 5.0A support disabling of the PM Timer, when the respective FADT flag is unset. Thus, drop this guard. For platforms without hardware PM Timer (Apollo Lake, Gemini Lake) the Kconfig `USE_PM_ACPI_TIMER` depends on `!NO_PM_ACPI_TIMER`. As of this change, new platforms must either implement code for disabling the hardware PM timer or select `NO_PM_ACPI_TIMER` if no such is present.

2021-09-16drivers/intel/fsp2_0: Refactor MultiPhaseSiInit API calling methodSubrata Banik
FspMultiPhaseSiInit API was introduced with FSP 2.2 specification onwards. EnableMultiPhaseSiliconInit is an arch UPD also introduced as part of FSP 2.2 specification to allow calling FspMultiPhaseSiInit API. However, some platforms adhere to the FSP specification but don't have arch UPD structure, for example : JSL, TGL and Xeon-SP. Out of these platforms, TGL supports calling of FspMultiPhaseSiInit API and considered EnableMultiPhaseSiliconInit as a platform-specific UPD rather than an arch UPD to allow calling into FspMultiPhaseSiInit API. It is important to ensure that the UPD setting and the callback for MultiPhaseInit are kept in sync, else it could result in broken behavior e.g. a hang is seen in FSP if EnableMultiPhaseSiliconInit UPD is set to 1 but the FspMultiPhaseSiInit API call is skipped. This patch provides an option for users to choose to bypass calling into MultiPhaseSiInit API and ensures the EnableMultiPhaseSiliconInit UPD is set to its default state as `disable` so that FSP-S don't consider MultiPhaseSiInit API is a mandatory entry point prior to calling other FSP API entry points. List of changes: 1. Add `FSPS_HAS_ARCH_UPD` Kconfig for SoC to select if `FSPS_ARCH_UPD` structure is part of `FSPS_UPD` structure. 2. Drop `soc_fsp_multi_phase_init_is_enable()` from JSL and Xeon-SP SoCs, a SoC override to callout that SoC doesn't support calling MultiPhase Si Init is no longer required. 3. Add `FSPS_USE_MULTI_PHASE_INIT` Kconfig for SoC to specify if SoC users want to enable `EnableMultiPhaseSiliconInit` arch UPD (using `fsp_fill_common_arch_params()`) and execute FspMultiPhaseSiInit() API. 4. Presently selects `FSPS_USE_MULTI_PHASE_INIT` from IA TCSS common code. 5. Add `fsp_is_multi_phase_init_enabled()` that check applicability of MultiPhase Si Init prior calling FspMultiPhaseSiInit() API to honor SoC users' decision. 6. Drop `arch_silicon_init_params()` from SoC as FSP driver (FSP 2.2) would check the applicability of MultiPhase Si Init prior calling FspMultiPhaseSiInit() API. Additionally, selects FSPS_HAS_ARCH_UPD for Alder Lake as Alder Lake FSPS_UPD structure has `FSPS_ARCH_UPD` structure and drops `arch_silicon_init_params()` from SoC `platform_fsp_silicon_init_params_cb()`. Skip EnableMultiPhaseSiliconInit hardcoding for Tiger Lake and uses the fsp_is_multi_phase_init_enabled() function to override EnableMultiPhaseSiliconInit UPD prior calling MultiPhaseSiInit FSP API. TEST=EnableMultiPhaseSiliconInit UPD is getting set or reset based on SoC user selects FSPS_USE_MULTI_PHASE_INIT Kconfig.
