Issue #620 has been updated by Teej Tj.
Tj here (identified the problem commit). I've been working with hustlerone in #coreboot:matrix.org for a few days on this and other issues. Rudolf: your comment in commit 97dbfd309 "TODO: Test on platforms that have FSRM (Ivy Bridge and newer)." cued me in as this possibly being the cause of the Lenovo X230 regression. I'm currently writing a patch for hustlerone to figure out the cause that conditionally reverts parts of the commit. The most obvious changes are: 1. MTRR 2. splitting of cache fill/clear 3. possibly the rep stosl using ERSM in Ivy Bridge influenced by the 64-byte stride for the modification loop ---------------------------------------- Bug #620: X230(t) does not work since commit 97dbfd3098ae12ef3f51e5f95cd6d66c25214205 was merged https://ticket.coreboot.org/issues/620#change-2204 * Author: Hustler One * Status: New * Priority: High * Category: coreboot common code * Target version: main * Start date: 2025-12-31 * Affected versions: main * Related links: https://www.reddit.com/r/coreboot/comments/1pu5vlp/x230t_does_not_get_past_postcar/ https://www.reddit.com/r/coreboot/comments/1pyzcvf/no_video_output_with_updated_coreboot_x230_4132512/ * Affected hardware: x230t ---------------------------------------- Releases 25.09, 25.12 are affected. 25.06 works. The commit 97dbfd3098ae12ef3f51e5f95cd6d66c25214205 prevents the x230t from going past the `postcar` stage, hence it being inoperable since it won't load into the main payload. I have attempted to debug using flashconsole but the trail runs cold after `postcar`. Credit to iam_tj for finding the commit. Also, Libreboot is somehow unaffected by this. I don't know if lbmk undoes this commit or not at this time. -- You have received this notification because you have either subscribed to it, or are involved in it.
