2024-02-02lib: Move IP checksum to commonlibJulius Werner
This patch moves the IP checksum algorithm into commonlib to prepare for it being shared with libpayload. The current implementation is ancient and pretty hard to read (and does some unnecessary questionable things like the type-punning stuff which leads to suboptimal code generation), so this reimplements it from scratch (that also helps with the licensing). This algorithm is prepared to take in a pre-calculated "wide" checksum in a machine-register-sized data type which is then narrowed down to 16 bits (see RFC 1071 for why that's valid). This isn't used yet (and the code will get optimized out), but will be used later in this patch series for architecture-specific optimization.

2024-02-02drivers/intel/gma: Add missing parentheses to brightness ACPIJonathon Hall
Commit d25277666829 ("tree: Replace And(a,b) with ASL 2.0 syntax") replaced two instances of `And(var, mask) == 0` with `var & mask == 0`. This expression needs parentheses - `(var & mask) == 0`. Without parentheses, it is always false, since the masks are nonzero (`var & (mask == 0)`; `var & 0`; `0`). This caused brightness changes on Intel GMA to take longer than normal since the status was never checked. The brightness would change immediately, but another brightness change could not occur until the first change timed out. This was most noticeable in KDE, which waits for the brightness change to complete before accepting another brightness up/down keypress. Tapping brightness up/down repeatedly would take much longer to reach max/min brightness due to many presses being ignored. It is noticeable in GNOME as well but less obvious. Tapping brightness up/down repeatedly would handle all keypresses, but the display's actual brightness would lag behind and skip some intermediate steps. I tested both Librem 13v2 and Librem 14, as far as I know this would apply to all systems configuring brightness with Intel GMA. Test: Verify brightness keys respond quickly again on Librem 13v2 / 14.

Macros can be confusing on their own; hiding commas make things worse. This can sometimes be downright misleading. A "good" example would be the code in soc/intel/xeon_sp/spr/chip.c: CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev, This appears as CHIP_NAME() being some struct when in fact these are defining 2 separate members of the same struct. It was decided to remove this macro altogether, as it does not do anything special and incurs a maintenance burden.

2023-10-20drivers/intel/fsp2_0: Support embedding a second FSP-M/FSP-SJonathon Hall
Support embedding a second FSP-M/FSP-S binary for an SoC that can select one at runtime. Comet Lake v1 and v2 are different steppings of the same SKUs, but they require different FSP binaries. Supporting both in a single build requires embedding both FSPs and selecting one at runtime based on the CPUID. This is desirable for a product that may have different CPU steppings but is not otherwise differentiated enough for a separate firmware build. An SoC can select PLATFORM_USES_SECOND_FSP to indicate that two FSP-M/ FSP-S binaries are required. Implement soc_select_fsp_m_cbfs() and soc_select_fsp_s_cbfs() to choose one based on platform-specific criteria. For Comet Lake, the first FSP is CML v1 and the second is CML v2, but in principle a platform could define any meaning for the first and second FSP. FSP-T is not affected, only one FSP-T can be embedded if FSP_CAR is used. Only one set of FSP headers is used, which is sufficient for Comet Lake v1/v2; their headers are equivalent. ADD_FSP_BINARIES, FSP_USE_REPO, and FSP_FULL_FD are supported for both sets of FSP-S/FSP-M but cannot be configured separately, both use the same configuration.

2023-09-14x86: Add .data section support for pre-memory stagesJeremy Compostella
x86 pre-memory stages do not support the `.data` section and as a result developers are required to include runtime initialization code instead of relying on C global variable definition. To illustrate the impact of this lack of `.data` section support, here are two limitations I personally ran into: 1. The inclusion of libgfxinit in romstage for Raptor Lake has required some changes in libgfxinit to ensure data is initialized at runtime. In addition, we had to manually map some `.data` symbols in the `_bss` region. 2. CBFS cache is currently not supported in pre-memory stages and enabling it would require to add an initialization function and find a generic spot to call it. Other platforms do not have that limitation. Hence, resolving it would help to align code and reduce compilation based restriction (cf. the use of `ENV_HAS_DATA_SECTION` compilation flag in various places of coreboot code). We identified three cases to consider: 1. eXecute-In-Place pre-memory stages - code is in SPINOR - data is also stored in SPINOR but must be linked in Cache-As-RAM and copied there at runtime 2. `bootblock` stage is a bit different as it uses Cache-As-Ram but the memory mapping and its entry code different 3. pre-memory stages loaded in and executed from Cache-As-RAM (cf. `CONFIG_NO_XIP_EARLY_STAGES`). eXecute-In-Place pre-memory stages (#1) require the creation of a new ELF segment as the code segment Virtual Memory Address and Load Memory Address are identical but the data needs to be linked in cache-As-RAM (VMA) but to be stored right after the code (LMA). Here is the output `readelf --segments` on a `romstage.debug` ELF binary. Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align LOAD 0x000080 0x02000000 0x02000000 0x21960 0x21960 R E 0x20 LOAD 0x0219e0 0xfefb1640 0x02021960 0x00018 0x00018 RW 0x4 Section to Segment mapping: Segment Sections... 00 .text 01 .data Segment 0 `VirtAddr` and `PhysAddr` are at the same address while they are totally different for the Segment 1 holding the `.data` section. Since we need the data section `VirtAddr` to be in the Cache-As-Ram and its `PhysAddr` right after the `.text` section, the use of a new segment is mandatory. `bootblock` (#2) also uses this new segment to store the data right after the code and load it to Cache-As-RAM at runtime. However, the code involved is different. Not eXecute-In-Place pre-memory stages (#3) do not really need any special work other than enabling a data section as the code and data VMA / LMA translation vector is the same. TEST=#1 and #2 verified on rex and qemu 32 and 64 bits: - The `bootblock.debug`, `romstage.debug` and `verstage.debug` all have data stored at the end of the `.text` section and code to copy the data content to the Cache-As-RAM. - The CBFS stages included in the final image has not improperly relocated any of the `.data` section symbol. - Test purposes global data symbols we added in bootblock, romstage and verstage are properly accessible at runtime #3: for "Intel Apollolake DDR3 RVP1" board, we verified that the generated romstage ELF includes a .data section similarly to a regular memory enabled stage.

2023-09-05drivers/intel/fsp2_0: Introduce MRC cache store after FSP-M/S APIsSubrata Banik
This patch refactors the existing MRC cache storing logic, which was spread between the ROM and RAM stages, into a single early MRC cache store stage. The only exception is when SoC user selects FSP_NVS_DATA_POST_SILICON_INIT to store MRC cache from ramstage (after FSP-S). It reverts all the boot-state logic previously used to locate and store MRC cache from NVS HOB into NVS because majority of the platform can potentially use the early MRC cache store with improved memory caching at the pre-RAM phase (with the ramtop implementation). The only exception is the Xeon SP platform, which currently locates the MRC cache post in FSP-S (at ramstage). Therefore, this patch provides an API to the FSP 2.x silicon init code to perform late storing of the MRC cache. In majority cases the updated logic, the romstage (post FSP-M) will attempt to save the MRC cache. Platform that selects FSP_NVS_DATA_POST_SILICON_INIT config performs the same operation post FSP-S. Depending on whether the MRC_STASH_TO_CBMEM config is enabled, the MRC cache will either be written directly to NVRAM at the romstage or stashed into CBMEM for a late NVRAM write at ramstage.

2023-09-04{drivers/intel/fsp2_0, soc/intel}: Rename `SAVE_MRC_AFTER_FSPS` configSubrata Banik
This patch renames `SAVE_MRC_AFTER_FSPS` config to `FSP_NVS_DATA_POST_SILICON_INIT` to highlight the violation in the Xeon SP FSP implementation, where the FSP Silicon Init API produces Non-Volatile Storage (NVS) instead of the FSP-Memory Init API. According to the FSP 2.x specification (section 11.3), the FSP populates the NVS data using the FSP_NON_VOLATILE_STORAGE_HOB and expects the boot firmware to parse the FSP_NON_VOLATILE_STORAGE_HOB after the FspMemoryInit() API in API mode. However, not all Intel SoC platforms that support the FSP 2.x specification adhere to this requirement. For example, the FSP binary for XEON SP platform produces NVS data (aka FSP_NON_VOLATILE_STORAGE_HOB) after the FspSiliconInit() API. Therefore, attempting to locate NVS data after the FspMemoryInit() API on these platforms would result in an error. The `save_mrc_data.c` implementation provides the required hooks to locate the NVS post FSP-Silicon Init and store into Non-Volatile Storage. BUG=b:296704537 TEST=Able to build and boot Intel Xeon SP w/o any functional impact.

2023-04-12Reland "drivers/intel/dptf: Add multiple fan support under dptf"Sumeet Pawnikar
This reverts commit 4dba71fd25c91a9e610287c61238a8fe24452e4e. Add multiple fan support for dptf policies. This also fixes the Google Meet resolution drop issue as per b:246535768 comment#12. When system starts Google Meet video call, it uses the hardware accelerated encoder as expected. But, as soon as another system connects to the call, an immediate fallback is observed from hardware to software encoder. Due to this, Google Meet resolution dropped from 720p to 180p. This issue is observed on Alder Lake-N SoC based fanless platforms. This same issue was not seen on fan based systems. With the fix in dptf driver where fan configures appropriate setting for only fan participant, not for other device participants, able to see consistent 720p resolution. BUG=b:246535768,b:235254828 BRANCH=None TEST=Built and tested on Alder Lake-P Redrix system for two fans support and on Alder Lake-N fanless systems. With this code change Google Meet resolution drop not observed.

2023-01-26soc/intel/alderlake: Wait for panel power cycle to completeJeremy Compostella
The Alder Lake PEIM graphics driver executed as part of the FSP does not wait for the panel power cycle to complete before it initializes communication with the display. It can result in AUX channel communication time out and PEIM graphics driver failing to bring up graphics. If we have performed some graphics operation in romstage, it is possible that a panel power cycle is still in progress. To prevent any issue with the PEIM graphics driver it is preferable to ensure that panel power cycle is complete.

2023-01-26drivers/intel/gma: Use libgfxinit Update_Output to turn off graphicsJeremy Compostella
We were using the libgfxinit `Initialize' function with the `Clean_State' parameter because the more appropriate `Update_Output' function was not performing all the necessary clean up operations for the PEIM driver to be successful when libgfxinit was used in romstage. Thanks to a lot of experiments and some log analysis efforts, we were able to identify the missing operation and fix the `Update_Output' function (cf. https://review.coreboot.org/c/libgfxinit/+/72123). The `initialized' global variable is now unnecessary as we track the initialization in the Ada code instead. Since the `Update_Output' function does not return any value, this patch modifies the `gma_gfxstop' prototype accordingly. This does not have any impact as the return value was not used anyway.

Prior to Tiger Lake, all DPTF devices used 7-character EISA IDs. If selected, the 7-character _HIDs will be emitted, otherwise, it will use the "new" style, which are regular 8-character _HIDs.

2022-12-19drivers/intel/fsp2_0: Implement `mps2_noop_get_number_of_processors()`Subrata Banik
This patch implements mps2_noop_get_number_of_processors() API with minimal information required for Intel MTL FSP to utilise the `MP_SERVICES_PPI_V2_NOOP` config. The major difference between Intel ADL and MTL FSP in terms of doing CPU feature programming aka utilizing MP PPI wrapper code is that, starting with MTL, FSP has dropped the `SkipMpInit` UPD. It means now, coreboot doesn't have any way to skip FSP doing MP Init operation. But during ADL, coreboot had introduced the MP_SERVICES_PPI_V2_NOOP config that is used to skip FSP about actually running any CPU feature programming on APs. The idea is to use the same config even in MTL to provide only the must have information (to bypass any assert in FSP during debug image) to FSP. Passing `FSP_UNSUPPORTED` from mps2_noop_get_number_of_processors() results in `assert` while compiling FSP in debug mode hence, implementing the function to pass only the information about BSP being the active processor along with passing `FSP_SUCCESS` (eventually it makes FSP happy and doesn't run into any issue in debug and/or release mode). TEST=Able to build and boot Google/Rex and Google/Kano while coreboot skip calling into FSP for doing MP init.

2022-12-06drivers/intel/fsp2_0: Update MRC cache in ramstageReka Norman
Currently the MRC cache is updated in romstage, immediately after returning from FSP-M. Since cbmem is not cached in romstage, the update is slow (~6 ms on nissa). Specifically, the new MRC data returned by the FSP is stored in the FSP reserved memory in cbmem, so hashing the new data is slow. Move the MRC cache update to ramstage, where cbmem is cached. On nissa, this saves ~5 ms of boot time. Before: 552:finished loading ChromeOS VPD (RW) 631,667 (16) 3:after RAM initialization 637,703 (6,036) 4:end of romstage 650,307 (12,603) After: 552:finished loading ChromeOS VPD (RW) 631,832 (15) 3:after RAM initialization 633,002 (1,169) 4:end of romstage 645,582 (12,580) In ramstage, save_mrc_data() takes ~138 us. BUG=b:242667207 TEST=MRC caching still works as expected on nivviks - after clearing the MRC cache, memory is retrained on the next boot, but cached data is used on subsequent boots.

This reverts commit 095c931cf12924da9011b47aa64f4a6f11d89f13. Previously cpu_info() was implemented with a struct on top of an aligned stack. As FSP changed the stack value cpu_info() could not be used in FSP context (which PPI is). Now cpu_info() uses GDT segments, which FSP does not touch so it can be used. This also exports cpu_infos from cpu.c as it's a convenient way to get the struct device * for a certain index. TESTED on aldrvp: FSP-S works and is able to run code on APs.
