2024-04-06add t440p/w541 configs using broadwell mrcLeah Rowe
broadwell mrc enables both igpu and dgpu to be enabled at any given time. if the onboard (intel) gpu is set as primary, the logic to disable it is not executed within coreboot; instead, the igpu is used for vga decode. on some t440p/w541 thinkpads, both an intel and nvidia gpu are present. in this setup, the intel gpu must be used for vga, and all output, but rendering can be offloaded to the nvidia gpu (nvidia optimus). optimus would never work on haswell mrc.bin, because it always disables the igpu when a dgpu is present, so a hack exists in coreboot that hides the dgpu from mrc, so that the igpu remains enabled. broadwell mrc doesn't do this, so the option to hide PEG devices has been disabled in these configs. the broadwell mrc has better peg device handling, and can support 16gb modules on broadwell hardware; it may well support these modules on haswell hardware too, though ddr3 sodimms are very hard to find (and expensive).

2024-04-06add 9020 sff/mt targets that use broadwell mrcLeah Rowe
broadwell mrc has better peg handling and can support 16gb modules on broadwell machines - the blob can be used on haswell machines too, instead of haswell mrc, and it might support 16gb modules on these machines (not yet tested, but using broadwell mrc does at least boot as reliably as haswell mrc anyway) one little quirk with haswell mrc is that it actually handles vga decode, disabling the igpu entirely, when a dgpu is used. the broadwell mrc enables both GPUs and does not handle vga decoding, so we must handle this the usual way; my patch for this was merged upstream and i'm also adding it to libreboot, which currently uses an older coreboot revision. this is needed for dgpu to work. see patch: 0040-nb-haswell-Disable-iGPU-when-dGPU-is-used.patch broadwell mrc may also make dealing with nvidia optimus setups more reliable, on laptops that have nvidia GPUs, but this patch does not add bmrc configs for t440p/w541 NOTE: on t440p/w541 laptops with nvidia graphics, the video output is wired to intel but rendering can be offloaded to nvidia. in this setup, we want vga decode to be done on intel, so i've set these configs to enable CONFIG_ONBOARD_VGA_IS_PRIMARY (set it to y) Signed-off-by: Leah Rowe <leah@libreboot.org>

2024-02-04add vga-only 9020 configLeah Rowe
on a dgpu setup, igpu was still in use, when tested by a user. do separate roms that don't enable anything vga in coreboot, relying instead only on seabios to execute a vga rom. these roms will only work if you have a graphics card. Signed-off-by: Leah Rowe <info@minifree.org>
2024-02-04NEW BOARD: Dell OptiPlex 9020 MT (and 7020 MT)Leah Rowe
Specifically the MT versions. The SFF versions will be added separately, in a later commit. See: https://review.coreboot.org/c/coreboot/+/55232 This patch has been added, from patchset 31. It still has some unresolved issues, on that patchset, but it should boot. See commit message there. Of note: I've enabled PCI REBAR, though it's unknown whether it will work (some comments there about it though, on that gerrit page). I've also set CBFS size to 8MB, not the full size of the BIOS region; this is required on the T440p which uses the same mrc.bin file, to get S3 working. TSEG stage cache disabled, as on other Haswell boards. The setup: SeaBIOS-only as first payload, but with GRUB enabled as secondary payload. The _grubonly setup has been enabled here. This way, the config will work on iGPU and dGPU setups without issue. Signed-off-by: Leah Rowe <info@minifree.org>
2024-01-12REMOVE MAINBOARD: lenovo x201Leah Rowe
with neutered ME, fan control fails. while there are ways to mitigate it, many users will not, and will likely see their system overheat, which is very dangerous. this bug (failed fan control on neutered ME) only affects arrandale machines such as lenovo x201. the newer machines are not affected by this. other arrandale machines will probably not be added to libreboot because of this, or they will be subject to further testing.

2024-01-10NEW MAINBOARD: HP EliteBook 820 G2Leah Rowe
This is of Broadwell platform, one generation above Haswell. Of note: this uses HP Sure Start. Although the flash is 16MB, our CBFS section (and IFD configuration) assumes 12MB flash, so the final 4MB will be left unflashed on installation, after blanking the private flash. The coreboot documents have more information about this. Some minor design changes in lbmk were made, to accomodate this port: Support for extracting refcode binaries added (pulled from Google recovery images). The refcode file is an ELF that initialises the MRC and the PCH. It is also responsible for enabling or disabling the Intel GbE device, where Google does not enable it, but lbmk modifies it per the instructions on the coreboot documentation, so as to enable Intel GbE. Google's recovery image stores the refcode as a stage file, but coreboot changed the format (for CBFS files) after 4.13 so coreboot 4.13's cbfstool is used to extract refcode. This realisation made me also change the script logic to use a cbfstool and ifdtool version matching the coreboot tree, for all parts of lbmk, whereas lbmk previously used only the default tree for cbfstool/ifdtool, on insertion and deletion of vendor files - it was 81dc20e744 that broke extraction of refcode on google's recovery images, where google used an older version of cbfstool to insert the files in their coreboot ROMs. A further backported patch has been added, copying coreboot revision f22f408956 which is a build fix from Nico Huber. Iru Cai submitted an ACPI bugfix after the revision lbmk currently uses, for coreboot/default, and this fix is needed for rebooting to work on Linux 6.1 or higher. This patch has been backported to lbmk, while it still uses the same October 2023 revision of coreboot. Broadwell MRC is inserted at the same offset as Haswell, so I didn't need to tweak that.

2023-12-23dell/e6400nvidia_4mb: new configuration (nvidia)Leah Rowe
the e6400_4mb target has libgfxinit and (if seabios) vgarom initialisation, but has issues on the nvidia model, even when using nomodeset. with this target, e6400nvidia_4mb, only the vgarom initialisation is used, libgfxinit is disabled. on nvidia models, this one should work a little bit better. specifically: nouveau crashes on this machine, with libreboot installed, but you can use nomodeset. however, when libgfxinit is also enabled, nomodeset no longer works properly. so this target disables all video initialisation in coreboot. only seabios will initialise anything video-related, by executing the vga option rom.

Inside the BIOS update, there's 68SCE and 68SCF variants. Based on Qubes HCL and browsing linux-hardware.org, these are Probook 6360b and Elitebook 8460p respectively. I checked the KBC1126 EC Firmwares within the update file, both use the exact same firmware images. Following-up will be a very similar but untested port for 6360b.

2023-10-29add lenovo x201 supportLeah Rowe
note: me6_update_parser needs to be written, similar to me7_update_parser, to generate the partition tables within intel me6 on lenovo bios updates. the current logic in lbmk goes like this: mkdir -p vendorfiles/cache/ and save your factory dump as: vendorfiles/cache/x201_factory.rom the build system has been modified, in such a way as to support extracting me.bin (which is the full one) and then neutering from this. this is done automatically, if the file is present, but you must first insert that file there, which means you'll need a dump of the original boot flash on your thinkpad x201 Signed-off-by: Leah Rowe <leah@libreboot.org>
