2014-05-06Introduce stage-specific architecture for corebootFurquan Shaikh
Make all three coreboot stages (bootblock, romstage and ramstage) aware of the architecture specific to that stage i.e. we will have CONFIG_ARCH variables for each of the three stages. This allows us to have an SOC with any combination of architectures and thus every stage can be made to run on a completely different architecture independent of others. Thus, bootblock can have an x86 arch whereas romstage and ramstage can have arm32 and arm64 arch respectively. These stage specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain and compiler flags for every stage. These options can be considered as either arch or modes eg: x86 running in different modes or ARM having different arch types (v4, v7, v8). We have got rid of the original CONFIG_ARCH option completely as every stage can have any architecture of its own. Thus, almost all the components of coreboot are identified as being part of one of the three stages (bootblock, romstage or ramstage). The components which cannot be classified as such e.g. smm, rmodules can have their own compiler toolset which is for now set to *_i386. Hence, all special classes are treated in a similar way and the compiler toolset is defined using create_class_compiler defined in Makefile. In order to meet these requirements, changes have been made to CC, LD, OBJCOPY and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others. Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the toolsets are defined using create_class_compiler. Few additional macros have been introduced to identify the class to be used at various points, e.g.: CC_$(class) derives the $(class) part from the name of the stage being compiled. We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER as they do not make any sense for coreboot as a whole. All these attributes are associated with each of the stages.

Start using the rmodtool for generating rmodules. rmodule_link() has been changed to create 2 rules: one for the passed in <name>, the other for creating <name>.rmod which is an ELF file in the format of an rmodule. Since the header is not compiled and linked together with an rmodule there needs to be a way of marking which symbol is the entry point. __rmodule_entry is the symbol used for knowing the entry point. There was a little churn in SMM modules to ensure an rmodule entry point symbol takes a single argument.

With the recent improvement 3d6ffe76f8a505c2dff5d5c6146da3d63dad6e82, speedup by CACHE_ROM is reduced a lot. On the other hand this makes coreboot run out of MTRRs depending on system configuration, hence screwing up I/O access and cache coherency in worst cases. CACHE_ROM requires the user to sanity check their boot output because the feature is brittle. The working configuration is dependent on I/O hole size, ram size, and chipset. Because of this the current implementation can leave a system configured in an inconsistent state leading to unexpected results such as poor performance and/or inconsistent cache-coherency Remove this as a buggy feature until we figure out how to do it properly if necessary.

2014-02-15coreboot: infrastructure for different ramstage loadersAaron Durbin
There are 2 methods currently available in coreboot to load ramstage from romstage: cbfs and vboot. The vboot path had to be explicitly enabled and code needed to be added to each chipset to support both. Additionally, many of the paths were duplicated between the two. An additional complication is the presence of having a relocatable ramstage which creates another path with duplication. To rectify this situation provide a common API through the use of a callback to load the ramstage. The rest of the existing logic to handle all the various cases is put in a common place.

2014-01-15Re-declare CACHE_ROM_SIZE as aligned ROM_SIZE for MTRRKyösti Mälkki
This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be set with values that are not power of 2. The region programmed as WB cacheable will include all of ROM_SIZE. Side-effects to consider: Memory region below flash may be tagged WRPROT cacheable. As an example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB. Since this can overlap CAR, we add an explicit test and fail on compile should this happen. To work around this problem, one needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and define a smaller region for WB cache. With this change flash regions outside CBFS are also tagged WRPROT cacheable. This covers IFD and ME and sections ChromeOS may use.

2013-12-05cpu: Remove BOARD_MICROCODE_CBFS_GENERATE Kconfig optionAlexandru Gagniuc
Commit * bdafcfa Add the Intel FSP 206ax CPU core support Introduced this option. This option was meant to have a board generate a CBFS file containing microcode. However, microcode generation used to be enabled by default when CPU_MICROCODE_IN_CBFS was selected. The introduction of BOARD_MICROCODE_CBFS_GENERATE killed that automatic default, which is not what we want. This option is misguided in the sense that it tends to introduce a non-default which had been intentionally a default. We now have to select two Kconfig options in order to generate microcode in CBFS, meaning one option is redundant.

2013-11-24haswell: Put each logical processor in its own P-state domainDuncan Laurie
The recommendation from Intel is to report each core as a separate logical domain in the _PSD table. This goes against the recommendation in the ACPI specification because all of these cores are on the same package and share a VR so they will do voltage transitions together. The reasoning is that with a larger number of logical processors the P-state often ramps too quickly resulting in higher power consumption. By exposing each core as a separate domain the OS can manage them individually allowing the socket to select the optimum frequency. $ cat /sys/firmware/acpi/tables/SSDT > /tmp/SSDT $ iasl -d /tmp/SSDT Processor (\_PR.CPU0, 0x00, 0x00000000, 0x00) { Name (_PSD, Package (0x01) { Package (0x05) { 0x05, 0x00, 0x00000000, 0x000000FE, 0x00000001 } }) } Processor (\_PR.CPU1, 0x01, 0x00000000, 0x00) { Name (_PSD, Package (0x01) { Package (0x05) { 0x05, 0x00, 0x00000001, 0x000000FE, 0x00000001 } }) } Processor (\_PR.CPU2, 0x02, 0x00000000, 0x00) { Name (_PSD, Package (0x01) { Package (0x05) { 0x05, 0x00, 0x00000002, 0x000000FE, 0x00000001 } }) } Processor (\_PR.CPU3, 0x03, 0x00000000, 0x00) { Name (_PSD, Package (0x01) { Package (0x05) { 0x05, 0x00, 0x00000003, 0x000000FE, 0x00000001 } }) } Change-Id: I5ef41b6ead4d88e9ba117003293dbc629c376803 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/48662 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/4130 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2013-07-10ec: Add romstage function for checking and rebooting ECDuncan Laurie
Now that we are executing VbInit() in coreboot we can end up in a situation where the recovery reason is consumed during VbInit (end of romstage) and then the EC is rebooted to RO during ramstage EC init, thereby losing the recovery reason. Two possiblities are to remove the EC check+reboot from ramstage and let it happen in depthcharge. This however means that the system has to boot all the way into depthcharge and then reboot the EC and the system again. Instead if we do a check in romstage before VbInit() is called then we can reboot the EC into RO early and avoid booting all the way to depthcharge first. This change adds a ramstage version the EC init function and calls it from the shared romstage code immediately after the PCH decode windows are setup.

2013-04-23Intel microcode: Return when `microcode_updates` is `NULL`Vladimir Serbinenko
Add a safety check in function `intel_update_microcode` to return when accidentally `NULL` is passed as `microcode_updates`, which would lead to a null pointer dereference later on. for (c = microcode_updates; m->hdrver; m = (const struct microcode *)c) { While at it, use `return NULL` for clarity in function `intel_microcode_find` and include the header file `stddef.h`. for it. The review of this patch had some more discussion on adding more comments and more detailed error messages. But this should be done in a separate patch. For clarity here some history, on how this was found and what caused the discussion and confusion. Originally when Vladimir made this improvement, selecting `CPU_MICROCODE_IN_CBFS` in Kconfig but not having the microcode blob `cpu_microcode_blob.bin` in CBFS resulted in a null pointer dereference later on causing a crash. for (c = microcode_updates; m->hdrver; m = (const struct microcode *)c) { Vladimir fixed this by returning if `microcode_updates` is `NULL`, that means no file is found and successfully tested this on his Lenovo X201. When pushing the patch to Gerrit for review, the code was rewritten though by Aaron in commit »intel microcode: split up microcode loading stages« (98ffb426) [1], which also returns when no file is found. So the other parts of the code were checked and the safety check as described above is added.

2013-04-01lynxpoint: split clearing and enabling of smmAaron Durbin
Previously southbridge_smm_init() was provided that did both the clearing of the SMM state and enabling SMIs. This is troublesome in how haswell machines bring up the APs. The BSP enters SMM once to determine if parallel SMM relocation is possible. If it is possible the BSP releases the APs to do SMM relocation. Normally, after the APs complete the SMM relocation, the BSP would then re-enter the relocation handler to relocate its own SMM space. However, because SMIs were previously enabled it is possible for an SMI event to occur before the APs are complete or have entered the relocation handler. This is bad because the BSP will turn off parallel SMM save state. Additionally, this is a problem because the relocation handler is not written to handle regular SMIs which can cause an SMI storm which effectively looks like a hung machine. Correct these issues by turning on SMIs after all the SMM relocation has occurred.

Also, use the dynamic cbmem library for allocating a stack in ram for romstage after CAR is torn down. Utilizing dynamic cbmem does mean that the cmem field in the gnvs chromeos acpi table is now 0.

2013-03-21haswell: support for parallel SMM relocationAaron Durbin
The haswell processors support the ability to save their SMM state into MSR space instead of the memory. This feaure allows for parallel SMM relocation handlers as well as setting the same SMBASE for each CPU since the save state memory area is not used. The catch is that in order determine if this feature is available the CPU needs to be in SMM context. In order to implement parallel SMM relocation the BSP enters the relocation handler twice. The first time is to determine if that feature is available. If it is, then that feature is enabled the BSP exits the relocation handler without relocating SMBASE. It then releases the APs to run the SMM relocation handler. After the APs have completed the relocation the BSP will re-enter the SMM relocation handler to relocate its own SMBASE to the final location. If the parallel SMM feature is not available the BSP relocates its SMBASE as it did before. This change also introduces the BSP waiting for the APs to relocate their SMBASE before proceeding with the remainder of the boot process. Ensured both the parallel path and the serial path still continue to work on cold, warm, and S3 resume paths.
