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>
2024-05-11remove all status checks. only handle release.Leah Rowe
the release variable is all we need, turning a target on or off for a given release. the status checks were prone to bugs, and unnecessary; it also broke certain benchmark scripts. it's better to keep the lbmk logic simpler. board status will be moved to the documentation instead.

2024-04-26build/roms: report status when building imagesLeah Rowe
export LBMK_VERSION_TYPE=x x can be: stable, unstable in target.cfg files, specify: status=x x can be: stable, unstable, broken, untested if unset, lbmk defaults to "unknown" if LBMK_VERSION_TYPE is set, no confirmation is asked if the given target matches what's set (but what's set in that environmental variable can only be stable or unstable) if LBMK_RELEASE="y", no confirmation is asked, unless the target is something other than stable/unstable "unstable" means it works, but has a few non-breaking bugs, e.g. broken s3 on dell e6400 whereas, if raminit regularly fails or it is so absolutely unreliable as to be unusable, then the board should be declared "broken" untested means: it has not been tested With this change, it should now be easier to track whether a given board is tested, in preparation for releases. When working on trees/boards, status can be set for targets. Also: in the board directory, you can add a "warn.txt" file which will display a message. For example, if a board has a particular quirk to watch out for, write that there. The message will be printed during the build process, to stdout. If status is anything *other* than stable, or it is unstable but LBMK_VERSION_TYPE is not set to "unstable", and not building a release, a confirmation is passed. If the board is not specified as stable or unstable, during a release build, the build is skipped and the ROM is not provided in that release; this is in *addition* to release="n" or release="y" that can be set in target.cfg, which will skip the release build for that target if "n" Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-04-24haswell: only provide NRI-based ROMs in releasesLeah Rowe
release="n" is set in target.cfg on haswell build targets that use mrc.bin script/update/release exports LBMK_RELEASE="y" script/build/roms skips building a given target if release="n" in target.cfg *and* LBMK_RELEASE="y" you could also do the export yourself before running ./build roms, for example: export LBMK_RELEASE="y" ./build roms all This would skip these ROM images. The native haswell raminit is now stable enough in my testing, that I wish to delete the MRC-based targets. This is in line with Libreboot's Binary Blob Reduction Policy, which states: if a blob can be avoided, it should be avoided. The problem is that users often run the inject script in *lbmk* from Git, instead of from the src release archive. I forsee some users running this on modern lbmk with older release images. If the mrc-based target isn't there, the user may use an NRI-based target name, and think it works; they will insert without MRC. I foresaw this ages ago, which is why Caleb and I ensured that the script checks hashes, and hashes are included in releases. Therefore: for the time being, keep the MRC-based configs in lbmk but do not include images for them in releases. This can be done indefinitely, but I'll probably remove those configs entirely at some point. On the following boards, Libreboot now will *only* provide NRI-based ROM images for the following machines: * Dell OptiPlex 9020 SFF * Dell OptiPlex 9020 MT * Lenovo ThinkPad T440p * Lenovo ThinkPad W541/W540 I now recommend exclusive use of NRI-based images, on Haswell hardware. It's stable enough in my testing, and now supports S3. Signed-off-by: Leah Rowe <leah@libreboot.org>
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>
