coreboot 4.19 release ======================================================================== The 4.19 release was completed on the 16th of January 2023. Since the last release, the coreboot project has merged over 1600 commits from over 150 authors. Of those authors, around 25 were first-time committers to the coreboot project. As always, we are very grateful to all of the contributors for helping to keep the project going. The coreboot project is different from many open source projects in that we need to keep constantly updating the codebase to stay relevant with the latest processors and technologies. It takes constant effort to just stay afloat, let alone improve the codebase. Thank you very much to everyone who has contributed, both in this release and in previous times. Note that the first set of tarballs posted for the 4.19 release had bad timestamps. This has been fixed. Hashes for all tarballs are at the bottom of this document. The 4.20 release is planned for the 20th of April, 2023. Significant or interesting changes ---------------------------------- ### Show all Kconfig options in saved config file; compress same The coreboot build system automatically adds a 'config' file to CBFS that lists the exact Kconfig configuration that the image was built with. This is useful to reproduce a build after the fact or to check whether support for a specific feature is enabled in the image. This file has been generated using the 'savedefconfig' Kconfig command, which generates the minimal .config file that is needed to produce the required config in a coreboot build. This is fine for reproduction, but bad when you want to check if a certain config was enabled, since many options get enabled by default or pulled in through another option's 'select' statement and thus don't show up in the defconfig. Instead coreboot now includes a larger .config instead. In order to save some space, all of the comments disabling options are removed from the file, except for those included in the defconfig. We can also LZMA compress the file since it is never read by firmware itself and only intended for later re-extraction via cbfstool, which always has LZMA support included. ### Toolchain updates * Upgrade LLVM from 15.0.0 to 15.0.6 * Upgrade CMake from 3.24.2 to 3.25.0 * Upgrade IASL from 20220331 to 20221020 * Upgrade MPFR from 4.1.0 to 4.1.1 ### Finished the conversion to ASL 2.0 syntax Until recently, coreboot still contained lots of code using the legacy ASL syntax. However, all ASL code was ported over to make use of the ASL 2.0 syntax and from this point on new ASL code should make use of it. Additional coreboot changes --------------------------- * Significant work was done to enable and build-test clang builds. * Added touchscreen power sequencing and runtime detection. * A number of patches were added to clean up and improve SMBIOS. * Work is in progress to unify and extend coreboot post codes. * Clean up for header includes is in progress with help from IWYU. * IOAPIC code has been reworked. * Support was added to superiotool for the NCT6687D-W chip. * Work is progressing to switch return values to enum cb_err instead of bool or other pass/fail indicators. * Clang builds are now working for most boards and are being build-tested. * 64-bit coreboot support is in progress and is working on a number of platforms. * A driver for EC used on various Clevo laptops was added. * Native Intel Lynxpoint code was added to replace the MRC.bin. * Work continued for the process of adding ops structures to the devicetree. * The crossgcc tool can now download the source packages, which are needed to build the coreboot toolchain, from coreboot’s own mirror if desired. * A document with useful external resources related to firmware development was added at Documentation/external_docs.md.

From the looks of the code, it was never ready for production as only engineering sample CPUIDs are supported. Intel Icelake code will be removed following 4.19 and any maintenance will be done on the 4.19 branch. This consists of the Intel Icelake SoC and Intel Icelake RVP mainboard. ### Intel Quark SoC & Galileo mainboard The SoC Intel Quark is unmaintained and different efforts to revive it failed. Also, the only user of this platform ever was the Galileo board. Thus, to reduce the maintenance overhead for the community, support for the following components will be removed from the master branch and will be maintained on the release 4.20 branch. * Intel Quark SoC * Intel Galileo mainboard Statistics from the 4.18 to the 4.19 release -------------------------------------------- - Total Commits: 1608 - Average Commits per day: 17.39 - Total lines added: 93786 - Average lines added per commit: 58.32 - Number of patches adding more than 100 lines: 80 - Average lines added per small commit: 38.54 - Total lines removed: 768014 - Total difference between added and removed: -674228 Significant Known and Open Issues --------------------------------- Issues from the coreboot bugtracker: https://ticket.coreboot.org/ ```eval_rst +-----+-----------------------------------------------------------------+ | # | Subject | +=====+=================================================================+ | 449 | ThinkPad T440p fail to start, continuous beeping & LED blinking | +-----+-----------------------------------------------------------------+ | 448 | Thinkpad T440P ACPI Battery Value Issues | +-----+-----------------------------------------------------------------+ | 446 | Optiplex 9010 No Post | +-----+-----------------------------------------------------------------+ | 445 | Thinkpad X200 wifi issue | +-----+-----------------------------------------------------------------+ | 439 | Lenovo X201 Turbo Boost not working (stuck on 2,4GHz) | +-----+-----------------------------------------------------------------+ | 427 | x200: Two battery charging issues | +-----+-----------------------------------------------------------------+ | 414 | X9SAE-V: No USB keyboard init on SeaBIOS using Radeon RX 6800XT | +-----+-----------------------------------------------------------------+ | 412 | x230 reboots on suspend | +-----+-----------------------------------------------------------------+ | 393 | T500 restarts rather than waking up from suspend | +-----+-----------------------------------------------------------------+ | 350 | I225 PCIe device not detected on Harcuvar | +-----+-----------------------------------------------------------------+ | 327 | OperationRegion (OPRG, SystemMemory, ASLS, 0x2000) causes BSOD | +-----+-----------------------------------------------------------------+ ``` Hashes for tarballs & signatures -------------------------------- Old tarballs: - a1f9ec1252a3cc19f0b4ba1a2b9d66ea9327499cbeecebd85377db7d5c68555d coreboot-4.19.tar.xz - 6ceaa39429a2094d75e4c8a94615ae60664ddad7b4115570b65b9bb516cbd96d coreboot-4.19.tar.xz.sig - 881a3477221d1b77e161759344df14eccda115086af3ef54e66485ae0eb2e5d9 coreboot-blobs-4.19.tar.xz - 16f4f1f7acc6203ce915ffea64edce8512bd9eb9e94e65db22a0cb5282a6e157 coreboot-blobs-4.19.tar.xz.sig New tarballs: - 65ccb2f46535b996e0066a1b76f81c8cf1ff3e27df84b3f97d8ad7b3e7cf0a43 coreboot-4.19.tar.xz - d3c52a209b8ccb49049960318f04f158dd47db52ebe6019d6a3dffe3196d9cbe coreboot-4.19.tar.xz.sig - 30214caed07b25f11e47bec022ff6234841376e36689eb674de2330a3e980cbc coreboot-blobs-4.19.tar.xz - 023d511d074703beab98c237c3e964dc7c598af86d5a0e2091195c68980b6c5d coreboot-blobs-4.19.tar.xz.sig
