It renders the game to the coreboot linear framebuffer, +and loads WAD files from CBFS. + + +### cpu/x86/smm_module_load: Rewrite setup_stub + +This code was hard to read as it did too much and had a lot of state +to keep track of. + +It also looks like the staggered entry points were first copied and +only later the parameters of the first stub were filled in. This +means that only the BSP stub is actually jumping to the permanent +smihandler. On the APs the stub would jump to wherever c_handler +happens to point to, which is likely 0. This effectively means that on +APs it's likely easy to have arbitrary code execution in SMM which is a +security problem. + +Note: This patch fixes CVE-2022-29264 for the 4.17 release. + + +### cpu/x86/smm_module_loader.c: Rewrite setup + +This code is much easier to read if one does not have to keep track of +mutable variables. + +This also fixes the alignment code on the TSEG smihandler setup code. +It was aligning the code upwards instead of downwards which would cause +it to encroach a part of the save state. + + +### cpu/x86/smm: Add sinkhole mitigation to relocatable smmstub + +The sinkhole exploit exists in placing the lapic base such that it +messes with GDT. This can be mitigated by checking the lapic MSR +against the current program counter. + + +### cpu/x86/64bit: Generate static page tables from an assembly file + +This removes the need for a tool to generate simple identity pages. +Future patches will link this page table directly into the stages on +some platforms so having an assembly file makes a lot of sense. + +This also optimizes the size of the page of each 4K page by placing +the PDPE_table below the PDE. + + +### cpu/x86/smm,lib/cbmem_console: Enable CBMEMC when using DEBUG_SMI + +This change will allow the SMI handler to write to the cbmem console +buffer. Normally SMIs can only be debugged using some kind of serial +port (UART). By storing the SMI logs into cbmem we can debug SMIs using +'cbmem -1'. Now that these logs are available to the OS we could also +verify there were no errors in the SMI handler. + +Since SMM can write to all of DRAM, we can't trust any pointers +provided by cbmem after the OS has booted. For this reason we store the +cbmem console pointer as part of the SMM runtime parameters. The cbmem +console is implemented as a circular buffer so it will never write +outside of this area. + + +### security/tpm/crtm: Add a function to measure the bootblock on SoC level + +On platforms where the bootblock is not included in CBFS anymore +because it is part of another firmware section (IFWI or a different +CBFS), the CRTM measurement fails. + +This patch adds a new function to provide a way at SoC level to measure +the bootblock. Following patches will add functionality to retrieve the +bootblock from the SoC related location and measure it from there. +In this way the really executed code will be measured. + + +### soc/amd/common/block/psp: Add platform secure boot support + +Add Platform Secure Boot (PSB) enablement via the PSP if it is not +already enabled. Upon receiving psb command, PSP will program PSB fuses +as long as BIOS signing key token is valid. +Refer to the AMD PSB user guide doc# 56654, Revision# 1.00. +Unfortunately this document is only available with NDA customers. + + +### drivers/intel/fsp2_0: Add native implementation for FSP Debug Handler + +This patch implements coreboot native debug handler to manage the FSP +event messages. + +'FSP Event Handlers' feature introduced in FSP to generate event +messages to aid in the debugging of firmware issues. This eliminates +the need for FSP to directly write debug messages to the UART and FSP +might not need to know the board related UART port configuration. +Instead FSP signals the bootloader to inform it of a new debug message. +This allows the coreboot to provide board specific methods of reporting +debug messages, example: legacy UART or LPSS UART etc. + +This implementation has several advantages as: +1. FSP relies on XIP 'DebugLib' driver even while printing FSP-S debug + messages, hence, without ROM being cached, post 'romstage' would + results into sluggish boot with FSP debug enabled. + This patch utilities coreboot native debug implementation which is + XIP during FSP-M and relocatable to DRAM based resource for FSP-S. + +2. This patch simplifies the FSP DebugLib implementation and remove the + need to have serial port library. Instead coreboot 'printk' can be + used for display FSP serial messages. Additionally, unifies the debug + library between coreboot and FSP. + +3. This patch is also useful to get debug prints even with FSP + non-serial image (refer to 'Note' below) as FSP PEIMs are now + leveraging coreboot debug library instead FSP 'NULL' DebugLib + reference for release build. + +4. Can optimize the FSP binary size by removing the DebugLib dependency + from most of FSP PEIMs, for example: on Alder Lake FSP-M debug binary + size is reduced by ~100KB+ and FSP-S debug library size is also + reduced by ~300KB+ (FSP-S debug and release binary size is exactly + same with this code changes). The total savings is ~400KB for each + FSP copy, and in case of Chrome AP firmware with 3 copies, the total + savings would be 400KB * 3 = ~1.2MB. + +Note: Need to modify FSP source code to remove 'MDEPKG_NDEBUG' as +compilation flag for release build and generate FSP binary with non-NULL +FSP debug wrapper module injected (to allow FSP event handler to execute +even with FSP non-serial image) in the final FSP.fd. + + +### security/tpm: Add vendor-specific tis functions to read/write TPM regs + +In order to abstract bus-specific logic from TPM logic, the prototype +for two vendor-specific tis functions are added in this +patch. tis_vendor_read() can be used to read directly from TPM +registers, and tis_vendor_write() can be used to write directly to TPM +registers. + + +### arch/x86: Add support for catching null dereferences through debug regs + +This commit adds support for catching null dereferences and execution +through x86's debug registers. This is particularly useful when running +32-bit coreboot as paging is not enabled to catch these through page +faults. This commit adds three new configs to support this feature: +DEBUG_HW_BREAKPOINTS, DEBUG_NULL_DEREF_BREAKPOINTS and +DEBUG_NULL_DEREF_HALT. + + +### drivers/i2c/generic: Add support for i2c device detection + +Add 'detect' flag which can be attached to devices which may or may not +be present at runtime, and for which coreboot should probe the i2c bus +to confirm device presence prior to adding an entry for it in the SSDT. + +This is useful for boards which may utilize touchpads/touchscreens from +multiple vendors, so that only the device(s) present are added to the +SSDT. This relieves the burden from the OS to detect/probe if a device +is actually present and allows the OS to trust the ACPI _STA value. + + +### util/cbmem: Add FlameGraph-compatible timestamps output + +Flame graphs are used to visualize hierarchical data, like call stacks. +Timestamps collected by coreboot can be processed to resemble +profiler-like output, and thus can be feed to flame graph generation +tools. + +Generating flame graph using https://github.com/brendangregg/FlameGraph: +``` + cbmem -S > trace.txt + FlameGraph/flamegraph.pl --flamechart trace.txt > output.svg +``` + + +### src/console/Kconfig: Add option to disable loglevel prefix + +This patch adds an option to disable loglevel prefixes. This patch helps +to achieve clear messages when low loglevel is used and very few +messages are displayed on a terminal. This option also allows to +maintain compatibility with log readers and continuous integration +systems that depend on fixed log content. + +If the code contains: + printk(BIOS_DEBUG, "This is a debug message!\n") +it will show as: + [DEBUG] This is a debug message! +but if the Kconfig contains: + CONFIG_CONSOLE_USE_LOGLEVEL_PREFIX=n +the same message will show up as + This is a debug message! + + +### util/cbmem: add an option to append timestamp + +Add an option to the cbmem utility that can be used to append an entry +to the cbmem timestamp table from userspace. This is useful for +bookkeeping of post-coreboot timing information while still being able +to use cbmem-based tooling for processing the generated data. + + +`-a | --add-timestamp ID: append timestamp with ID\n` + + +Additional changes +------------------ + +The following are changes across a number of patches, or changes worth +noting, but not needing a full description. + +* As always, general documentation, code cleanup, and refactoring +* Remove doxygen config files and targets +* Get clang compile working for all x86 platforms +* Work on updating checkpatch to match the current Linux version +* Timestamps: Rename timestamps to make names more consistent +* Continue updating ACPI code to ASL 2.0 +* Remove redundant or unnecessary headers from C files +* arch/x86/acpi_bert_storage.c: Use a common implementation +* Postcar stage improvements +* arch/x86/acpi: Consolidate POST code handling +* intel/common: Enable ROM caching in ramstage +* vendorcode/amd/agesa: Fix improper use of .data (const is important) +* sandybridge & gm45: Support setting PCI bars above 4G + + +Plans for Code Deprecation +-------------------------- + + +### Intel Icelake + +Intel Icelake is unmaintained.
