2024-01-31include/device/device.h: Remove CHIP_NAME() macroNicholas Sudsgaard
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.

2023-10-20cpu/intel/common: Define build time physical address reserved bitsJeremy Compostella
According the Intel Software Developer Manual, CPUID.80000008H:EAX[15:8] reports the physical-address width supported by the processor. Unfortunately, it does not necessarily reflect the physical-address space the system can actulally use as some of those bits can be reserved for internal hardware use. It is critical for coreboot to know the actual physical address size. Overestimating this size can lead to device resource overlaps due to the hardware ignoring upper reserved bits. On rex for instance, it creates some reboot hangs due to an overlap between thunderbolt and Input Output Manager (IOM) address space. As some SoCs, such as Meteor Lake, have physical address reserved bits which cannot be probed at runtime, this commit introduces `CPU_INTEL_COMMON_RESERVED_PHYS_ADDR_BITS' Kconfig to set the number of physical address reserved bits at compilation time for those SoCs. A runtime detection by hardware probing will be attempted if the value is 0 (default).

2023-10-20x86: Add pre-memory stages CBFS cache scratchpad supportJeremy Compostella
Having a CBFS cache scratchpad offers a generic way to decompress CBFS files through the cbfs_map() function without having to reserve a per-file specific memory region. This commit introduces the x86 `PRERAM_CBFS_CACHE_SIZE' Kconfig to set the pre-memory stages CBFS cache size. A cache size of zero disables the CBFS cache feature. The default value is 16 KB which seems a reasonable minimal value enough to satisfy basic needs such as the decompression of a small configuration file. This setting can be adjusted depending on the platform needs and capabilities. We have set this size to zero for all the platforms without enough space in Cache-As-RAM to accommodate the default size.

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.

2023-07-08cpu: Enable per-CPUID microcode loading in CBFSSubrata Banik
The current design of the `ucode-<variant>.bin` file combines all possible microcode per cpuid into a unified blob. This model increases the microcode loading time from RW CBFS due to higher CBFS verification time (the bigger the CBFS binary the longer the verification takes). This patch creates a provision to pack individual microcodes (per CPUID) into the CBFS (RO and RWs). Implementation logic introduces CPU_INTEL_MICROCODE_CBFS_SPLIT_BINS config which relies on converting Intel CPU microcode INC file into the binary file as per format specified as in `cpu_microcode_$(CPUID).bin`. For example: Intel CPU microcode `m506e3.inc` to convert into `cpu_microcode_506e3.bin` binary file for coreboot to integrate if CPU_INTEL_MICROCODE_CBFS_SPLIT_BINS config is enabled. Another config named CPU_INTEL_UCODE_SPLIT_BINARIES is used to specify the directory name (including path) that holds the split microcode binary files per CPUID for each coreboot variants. For example: if google/kunimitsu had built with Intel SkyLake processor with CPUID `506e3` and `506e4` then CPU_INTEL_UCODE_SPLIT_BINARIES refers to the directory path that holds the split microcode binary files aka cpu_microcode_506e3.bin and cpu_microcode_506e4.bin. Refer to the file representation below: |---3rdparty | |--- blobs | | |--- mainboard | | | |--- google | | | | |--- kunimitsu | | | | | |--- microcode_inputs | | | | | | |--- kunimitsu | | | | | | | |--- cpu_microcode_506e3.bin | | | | | | | |--- cpu_microcode_506e4.bin Users of this config option requires to manually place the microcode binary files per CPUIDs as per the given format (`cpu_microcode_$(CPUID).bin`) in a directory. Finally specify the microcode binary directory path using CPU_UCODE_SPLIT_BINARIES config. Additionally, modified the `find_cbfs_microcode()` logic to search microcode from CBFS by CPUID.

Previously BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES was selected for CPU_INTEL_HASWELL, CPU_INTEL_MODEL_{2065X,206AX} and others (see [2]).

This moves a lot of post code values, but unifies them between platforms, so that the same value means the same thing as much as possible. The P4-netburst code was the most extensive and most different, so that dictated the majority of the values. Three were two values there that didn't match the other files, so those two values, 0x22 & 0x29 have duplicate entries in the table. The rest of the entries are similar between platforms, though the values for many of them were moved to match the P4-netburst values. POST_BOOTBLOCK and POST_POSTCAR values are intended to eventually become global, while POST_SOC would be specific to the Intel platforms.

The patch fixes the typecasting issue, that is conversion from 'int' to 'unsigned long long int'. This changes value from '0x8000 0000' to '0xFFFF FFFF 8000 0000'. During unit testing, the argument is getting changed to an unexpected number which is resulting to an exception when IA32_HWP_REQUEST MSR is updated.

To deprecate VBOOT_VBNV_CMOS [1], replace VBOOT_VBNV_CMOS with VBOOT_VBNV_FLASH for Haswell. Currently BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES is selected for CPU_INTEL_HASWELL (see [2]).

Commit 27126f135dad3c0e2f91394e7088b2ff50220146 (cpu/intel/haswell: add Crystal Well CPU IDs) introduced new Haswell CPUIDs but did not include any µcode updates for them. It is unknown how this could have worked as the initial µcode inside the CPU can be quite unstable. Intel CPUs with support for FIT (Firmware Interface Table) can have their µcode updated before the x86 reset vector is executed. The µcode updates for Crystal Well CPUID 0x40661 can be found inside the intel-microcode submodule. There are no publicly available µcode updates for Crystal Well CPUID 0x40660 as it is a pre-production stepping, which is not meant to be used anymore. Hook up the available µcode updates for Crystal Well CPUs.

2022-09-20cpu/intel/haswell: Do not include useless µcode updatesAngel Pons
There are two types of Haswell/Broadwell platforms: Trad(itional) with separate CPU and PCH packages, and ULT/ULX where the CPU and PCH share one package. Mainboards can specify which platform type they are using the `INTEL_LYNXPOINT_LP` Kconfig option. There are so many differences between Trad and ULT/ULX that it's not worth doing runtime detection. The CPUIDs are different for Trad and ULT/ULX platforms, and so are the µcode updates. So, including Trad µcode updates in a coreboot image for an ULT/ULX mainboard makes no sense, and vice versa. Adapt the Makefile so that only relevant µcode updates are added. Also, add a few comments to indicate which updates correspond to which CPUs. TEST=Run binwalk on coreboot.rom to verify included µcode updates for: - Asrock B85M Pro4 (Haswell Trad) - HP Folio 9480M (Haswell ULT/ULX) - Purism Librem BDW (Broadwell ULT/ULX) Change-Id: I6dc9e94ce9fede15cbcbe6be577c48c197a9212a Signed-off-by: Angel Pons <th3fanbus@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/67524 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Arthur Heymans <arthur@aheymans.xyz>

Prior commit hash 0310d34c2 (cpu/intel/microcode: Have provision to re-load microcode patch) introduces an option to reload the microcode based on SoC selecting RELOAD_MICROCODE_PATCH config. This patch might potentially introduce a boot time regression (~30ms) when RELOAD_MICROCODE_PATCH kconfig is enabled as all cores might end up reloading the microcode without the proper need. Note: RELOAD_MICROCODE_PATCH kconfig is not yet selected by any SoC hence, it doesn't impact any coreboot project. The idea is reloading microcode depends on specific use case (for example: Skip FSP doing MP Init from Alder Lake onwards) hence, a follow up patch will create a newer API to allow reloading of microcode when RELOAD_MICROCODE_PATCH config is enabled.

2022-06-01cbfs: Add CBFS_TYPE_INTEL_FIT and exclude it from CBFS verificationJulius Werner
The Intel Firmware Interface Table (FIT) is a bit of an annoying outlier among CBFS files because it gets manipulated by a separate utility (ifittool) after cbfstool has already added it to the image. This will break file hashes created for CBFS verification. This is not actually a problem when booting, since coreboot never actually loads the FIT from CBFS -- instead, it's only in the image for use by platform-specific mechanisms that run before coreboot's bootblock. But having an invalid file hash in the CBFS image is confusing when you want to verify that the image is correctly built for verification. This patch adds a new CBFS file type "intel_fit" which is only used for the intel_fit (and intel_fit_ts, if applicable) file containing the FIT. cbfstool will avoid generating and verifying file hashes for this type, like it already does for the "bootblock" and "cbfs header" types. (Note that this means that any attempt to use the CBFS API to actually access this file from coreboot will result in a verification error when CBFS verification is enabled.)

2022-04-01cpu/intel/fit: Clear the FIT table when setting pointerArthur Heymans
When rebuilding coreboot the empty fit table added to added to CBFS stays the same so the build process sees no reason to update the file. In the meantime ifittool did update that file for instance to add microcode update entries. So each time coreboot is rebuilt the entries are appended to the FIT table which runs out of space at some point. One way to deal with this is to clear the fit table when setting the pointer inside the bootblock. TESTED: Now running 'make' again on prodrive/hermes does not report an error with a filled FIT table.

2022-03-08timestamps: Rename timestamps to make names more consistentJakub Czapiga
This patch aims to make timestamps more consistent in naming, to follow one pattern. Until now there were many naming patterns: - TS_START_*/TS_END_* - TS_BEFORE_*/TS_AFTER_* - TS_*_START/TS_*_END This change also aims to indicate, that these timestamps can be used to create time-ranges, e.g. from TS_BOOTBLOCK_START to TS_BOOTBLOCK_END.

2022-02-24nb/intel/ironlake: Fix some quickpath init magicAngel Pons
Correct some Quickpath initialisation steps according to findings from two different Intel reference code binaries as well as MCHBAR register dump comparisons between vendor firmware and coreboot. The MSR_TURBO_POWER_CURRENT_LIMIT information comes from EDK2 sources. Tested on Apple iMac 10,1 (Clarkdale, aka desktop Ironlake), QPI init now completes successfully instead of causing hangs before raminit. Also tested on HP ProBook 6550b (Arrandale, aka mobile Ironlake), still reaches payload (e.g. TianoCore).

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.
