3 daysvendor.sh: Remove T480 VGA ROM download handlingLeah Rowe
Libreboot's binary blob reduction policy is crystal clear: If a blob can be avoided, it must be avoided. The ThinkPad T480 was using Intel's VGA ROM for graphics initialisation very briefly, before Mate fixed libgfxinit. Since libgfxinit is fixed, the Intel VGA ROM is obsolete, so we should not be handling this at all. Similarly, the Nvidia ROM handling has been removed, because Mate is hard-disabling that in the coreboot code anyway, since the Nvidia dGPU didn't work when tested anyway. Even if it did, Libreboot's blob policy makes it clear that Intel graphics with native init from coreboot is to be the preferred option. Signed-off-by: Leah Rowe <leah@libreboot.org>
3 daysNEW MAINBOARD: ThinkPad T480SLeah Rowe
Added t480s delta to deguard, for MFS config. Updated coreboot/next to latest t480 patch set, which includes t480s. This porting was done by Mate Kukri. also includes experimental t480s support Also added a data.vbt file (not in the gerrit patch) for the T480s. I had to turn on 8254 legacy timer on t480s, otherwise SeaBIOS would hang. Same issue I saw on OptiPlex 3050 Micro. Minor issue: On S3 resume, nvme0n1 for example got renamed to nvme0n2. This caused a crash if running Linux from the nvme. I confirmed this via live USB distro. So this port will need some tweaking before it can be considered stable. Also uses libgfxinit, which Mate recently fixed. I'm going to enable libgfxinit on regular T480 next. Signed-off-by: Leah Rowe <leah@libreboot.org>

4 daysvendor.sh: Use the new deguard for 3050microLeah Rowe
I'm adding ThinkPad T480 support next, which requires the new revision of deguard. Mate Kukri changed the way deguard is used, in a rewrite of the project, so lbmk has to change too. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-09-24Add deguard logic for Dell OptiPlex 3050 MicroLeah Rowe
Copy the downloaded deguard source code into appdir, and patch it to run as part of lbmk, instead of standalone. The archived one in src/ is not directly used; instead, the hotpatched version is used. This is because the standalone version already has download logic for the .zip file, but we already cache that file in cache/ and use that. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-22lib.sh: more unified config handlingLeah Rowe
replace it with logic that simply uses "." to load files directly. for this, "vcfg" is added as a variable in coreboot target.cfg files, referring to a directory in config/vendor/ containing a file named pkg.cfg, and this file then contains the same variables as the erstwhile config/vendor/sources config/git files are now directories, also containing pkg.cfg files each with the same variables as before, such as repository link and commit hash this change results in a noticeable reduction in code complexity within the build system. unified reading of config files: new function setcfg() added to lib.sh setcfg checks if a config exists. if a 2nd argument is passed, it is used as a return value for eval, otherwise a string calling err is passed. setcfg output is passed through eval, to set strings based on config; eval must be used, so that the variables are set within the same scope, otherwise they'd be set within setcfg which could lead to some whacky results. there's still a bit more more to do, but this single change results in a substantial reduction in code complexity.

2024-05-29do not allow dashes in coreboot target namesLeah Rowe
Command: ./vendor download kcma-d8-rdimm_16mb Output was: include/lib.sh: line 115: kcma-d8-rdimm=config/vendor: No such file or directory That will have to be audited later on, but the recent more stringent error checking in vendor.sh triggered this previously untriggered error message. The error was in fact already occuring before, silently. Anyway, mitigate by renaming all coreboot targets so that they do not contain hyphens in the name. This should avoid triggering errors in that eval command, on line 115 in lib.sh Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-05-11remove haswell mrc blob (libre raminit stable now)Leah Rowe
broadwell mrc is retained, because it's needed on 820 g2 it's no longer needed on haswell, because nri is stable. nri is short for "native ram initialisation", and libreboot provides this for: thinkpad t440p, thinkpad w541, dell optiplex 9020 mt, and dell optiplex 9020 sff remove, in line with libreboot's binary blob reduction policy previous revisions, prior to the recent release, stated that it would be retained for compatibility, but it's really not right to retain it, because doing so violates libreboot's policy the recent release excluded mrc-based rom images for haswell machines, providing only those rom images that use the libre raminit, while retaining support for mrc in the build system, so that users could still run the lbmk inject script on older release roms that use mrc again: libreboot's binary blob reduction policy is very clear: https://libreboot.org/news/policy.html it is a policy that can be summarised, thus: if a blob can be avoided, it must be avoided. therefore, we will avoid the Haswell MRC raminit blob Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-05-03remove x220edp/x230edp (keep regular x220/x230)Leah Rowe
nitrocaster boards are hard to find nowadays and i'm not comfortable supporting the knockoff chinese gear; quality varies greatly, and i can't know how reliable they are. nitrocaster has been out of business so it's just not viable to support this mod anymore. in fact, keeping the eDP-based targets is a liability to libreboot. regular x220/x230 (non-eDP-modded) are retained. the eDP modkit from nitrocaster let you use eDP screens instead of lvds, on thinkpad x220 and x230, letting you use higher resolution screens. older lbmk revs can still be used, if you happen to come across one of these boards. i only recommend using the official nitrocaster board, if youcan find one unused. ymmv with the chinese gear. better just use an unmodded x230 or get a different machine.

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). (and currently untested, with this patch) Signed-off-by: Leah Rowe <leah@libreboot.org>
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>

2024-02-04NEW 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.

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.

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>
