From 429e91f90894d30bc2c6e165d6f2a743c61b76f3 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Sat, 1 Jun 2024 23:01:30 +0100 Subject: make GRUB multi-tree and re-add xhci patches Re-add xHCI only on haswell and broadwell machines, where they are needed. Otherwise, keep the same GRUB code. The xHCI patches were removed because they caused issues on Sandybridge-based Dell Latitude laptops. See: https://codeberg.org/libreboot/lbmk/issues/216 The issue was not reported elsewhere, including on the Haswell/Broadwell hardware where they are needed, but the build system could only build one version of GRUB. The older machines do not need xHCI patches, because they either do not have xHCI patches, or work (in GRUB) because they're in EHCI mode when running the payload. So, the problem is that we need the xHCI patches for GRUB on Haswell/Broadwell hardware, but the patches break Sandybridge hardware, and we only had the one build of GRUB. To mitigate this problem, the build system now supports building multiple revisions of GRUB, with different patches, and each given coreboot target can say which GRUB tree to use by setting this in target.cfg: grubtree="xhci" In the above example, the "xhci" tree would be used. Some generic GRUB config has been moved to config/data/grub/ and config/grub/ now looks like config/coreboot/ - also, the grub.cfg file (named "payload" in each tree) is copied to the GRUB source tree as ".config", then added to GRUB's memdisk in the same way, as grub.cfg. Several other design changes had to be made because of this: * grub.cfg in memdisk no longer automatically jumps to one in CBFS, but now shows a menuentry for it if available * Certain commands in script/trees are disabled for GRUB, such as *config make commands. * gnulib is now defined in config/submodule/grub/, instead of config/git/grub - and this mitigates an existing bug where downloading gnulib first would make grub no longer possible to download in lbmk. The coreboot option CONFIG_FINALIZE_USB_ROUTE_XHCI has been re-enabled on: Dell OptiPlex 9020 MT, Dell OptiPlex 9020 SFF, Lenovo ThinkPad T440p and Lenovo ThinkPad W541 - now USB should work again in GRUB. The GRUB payload has been re-enabled on HP EliteBook 820 G2. This change will enable per-board GRUB optimisation in the future. For example, we hardcode what partitions and LVMs GRUB scans because * is slow on ICH7-based machines, due to GRUB's design. On other machines, * is reasonably fast, for automatically enumerating the list of devices for boot. Use of * (and other wildcards) could enable our GRUB payload to automatically boot more distros, with minimal fuss. This can be done at a later date, in subsequent revisions.

Copyright and Related Rights. A Work made available under CC0 may be -+protected by copyright and related or neighboring rights ("Copyright and -+Related Rights"). Copyright and Related Rights include, but are not -+limited to, the following: -+ -+ i. the right to reproduce, adapt, distribute, perform, display, -+ communicate, and translate a Work; -+ ii. moral rights retained by the original author(s) and/or performer(s); -+iii. publicity and privacy rights pertaining to a person's image or -+ likeness depicted in a Work; -+ iv. rights protecting against unfair competition in regards to a Work, -+ subject to the limitations in paragraph 4(a), below; -+ v. rights protecting the extraction, dissemination, use and reuse of data -+ in a Work; -+ vi. database rights (such as those arising under Directive 96/9/EC of the -+ European Parliament and of the Council of 11 March 1996 on the legal -+ protection of databases, and under any national implementation -+ thereof, including any amended or successor version of such -+ directive); and -+vii. other similar, equivalent or corresponding rights throughout the -+ world based on applicable law or treaty, and any national -+ implementations thereof. -+ -+2. Waiver. To the greatest extent permitted by, but not in contravention -+of, applicable law, Affirmer hereby overtly, fully, permanently, -+irrevocably and unconditionally waives, abandons, and surrenders all of -+Affirmer's Copyright and Related Rights and associated claims and causes -+of action, whether now known or unknown (including existing as well as -+future claims and causes of action), in the Work (i) in all territories -+worldwide, (ii) for the maximum duration provided by applicable law or -+treaty (including future time extensions), (iii) in any current or future -+medium and for any number of copies, and (iv) for any purpose whatsoever, -+including without limitation commercial, advertising or promotional -+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each -+member of the public at large and to the detriment of Affirmer's heirs and -+successors, fully intending that such Waiver shall not be subject to -+revocation, rescission, cancellation, termination, or any other legal or -+equitable action to disrupt the quiet enjoyment of the Work by the public -+as contemplated by Affirmer's express Statement of Purpose. -+ -+3. Public License Fallback. Should any part of the Waiver for any reason -+be judged legally invalid or ineffective under applicable law, then the -+Waiver shall be preserved to the maximum extent permitted taking into -+account Affirmer's express Statement of Purpose. In addition, to the -+extent the Waiver is so judged Affirmer hereby grants to each affected -+person a royalty-free, non transferable, non sublicensable, non exclusive, -+irrevocable and unconditional license to exercise Affirmer's Copyright and -+Related Rights in the Work (i) in all territories worldwide, (ii) for the -+maximum duration provided by applicable law or treaty (including future -+time extensions), (iii) in any current or future medium and for any number -+of copies, and (iv) for any purpose whatsoever, including without -+limitation commercial, advertising or promotional purposes (the -+"License"). The License shall be deemed effective as of the date CC0 was -+applied by Affirmer to the Work. Should any part of the License for any -+reason be judged legally invalid or ineffective under applicable law, such -+partial invalidity or ineffectiveness shall not invalidate the remainder -+of the License, and in such case Affirmer hereby affirms that he or she -+will not (i) exercise any of his or her remaining Copyright and Related -+Rights in the Work or (ii) assert any associated claims and causes of -+action with respect to the Work, in either case contrary to Affirmer's -+express Statement of Purpose. -+ -+4. Limitations and Disclaimers. -+ -+ a. No trademark or patent rights held by Affirmer are waived, abandoned, -+ surrendered, licensed or otherwise affected by this document. -+ b. Affirmer offers the Work as-is and makes no representations or -+ warranties of any kind concerning the Work, express, implied, -+ statutory or otherwise, including without limitation warranties of -+ title, merchantability, fitness for a particular purpose, non -+ infringement, or the absence of latent or other defects, accuracy, or -+ the present or absence of errors, whether or not discoverable, all to -+ the greatest extent permissible under applicable law. -+ c. Affirmer disclaims responsibility for clearing rights of other persons -+ that may apply to the Work or any use thereof, including without -+ limitation any person's Copyright and Related Rights in the Work. -+ Further, Affirmer disclaims responsibility for obtaining any necessary -+ consents, permissions or other rights required for any use of the -+ Work. -+ d. Affirmer understands and acknowledges that Creative Commons is not a -+ party to this document and has no duty or obligation with respect to -+ this CC0 or use of the Work. -+ -+-------------------------------------------------------------------------------- -+ -+ Apache License -+ Version 2.0, January 2004 -+ http://www.apache.org/licenses/ -+ -+ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION -+ -+ 1.
