Issue #401 has been updated by Sean Rhodes. File edk2.txt added
Disabling MTRR in edk2 seems to cause other issues - the most obvious being the USB drivers constantly resetting. Universal Payload doesn't seem subject to the same issue ---------------------------------------- Bug #401: edk2 hangs indefiniately https://ticket.coreboot.org/issues/401#change-1046 * Author: Sean Rhodes * Status: New * Priority: Normal * Assignee: Arthur Heymans * Category: board support * Target version: none * Start date: 2022-07-08 * Affected versions: master * Affected hardware: Everything * Affected OS: Doesn't matter ---------------------------------------- Since CB:63555, edk2 will no longer boot and hangs indefiniately Various forks disable MTRR programming in edk2 (such as https://github.com/MrChromebox/edk2/commit/d641ea6920737fd9b9a94210e9a2e7636bfb3cdc) but this shouldn't be done as it breaks spec. Workarounds are to revert CB:64804, CB:63550, CB:64803 and CB:63555. ---Files-------------------------------- with_avph_patch.txt (65.8 KB) with_avph_patch_reverted.txt (64.6 KB) master.txt (91.9 KB) master_w_revert.txt (197 KB) edk2.txt (251 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.
