[M] Change in coreboot[master]: arch/arm64: Add EL1/EL2/EL3 support for arm64
by David Milosevic (Code Review) 26 Apr '23

26 Apr '23

David Milosevic has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/74798 ) Change subject: arch/arm64: Add EL1/EL2/EL3 support for arm64 ...................................................................... arch/arm64: Add EL1/EL2/EL3 support for arm64 Currently, arch/arm64 requires coreboot to run on EL3 due to EL3 register access. This might be an issue when, for example, one boots into TF-A first and drops into EL2 for coreboot afterwards. This patch aims at making arch/arm64 more versatile by removing the current EL3 constraint and allowing arm64 coreboot to run on EL1, EL2 and EL3. The strategy here, is to read coreboot's current EL via the 'currentel' register and choose the appropiate ELx register. So, for example, when running coreboot on EL1, we would not access vbar_el3 or vbar_el2 but instead vbar_el1. This way, we don't generate faults when accessing higher-EL registers. Currently only tested on the qemu-aarch64 target. Exceptions were tested by enabling FATAL_ASSERTS.

( https://review.coreboot.org/c/coreboot/+/74742 ) Change subject: util/cbmem: Add REG_NEWLINE flag to fix matching pattern ...................................................................... Patch Set 1: Code-Review+2 (1 comment) Commit Message: https://review.coreboot.org/c/coreboot/+/74742/comment/8c92478a_70056e57 PS1, Line 13: REG_NEWLINE > Thanks for the history and the great explanation. Wow, great find, thanks! So just to clarify my understanding, the switch to REG_EXTENDED actually has nothing to do with the problem, it doesn't affect the newline behavior. And the fact that it accidentally matches all the way to `"Starting depthcharge...\n"` is also irrelevant to the user-visible bug (even though it is unintended, and a bit wasteful). The only real issue is that the `.?` introduced may match a newline, and this will result in `cbmem -2` not displaying the correct boot iff the log does not contain loglevel markers. Part of the problem was also that CB:33779 introduced the `.*` when the original patch had used `[^\n]*` for the same purpose. I guess REG_NEWLINE is a better way to fix the same problem, though. Maybe we should change the `[^\n]*` to `.*` for consistency now, because it doesn't make a difference anymore. -- To view, visit https://review.coreboot.org/c/coreboot/+/74742 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: coreboot Gerrit-Branch: master Gerrit-Change-Id: I9e924349ead0fa7eea8b9ad5161138a4c4946ade Gerrit-Change-Number: 74742 Gerrit-PatchSet: 1 Gerrit-Owner: Konrad Adamczyk <konrada(a)google.com> Gerrit-Reviewer: Grzegorz Bernacki Gerrit-Reviewer: Jakub Czapiga <jacz(a)semihalf.com> Gerrit-Reviewer: Julius Werner <jwerner(a)chromium.org> Gerrit-Reviewer: Karthik Ramasubramanian <kramasub(a)google.com> Gerrit-Reviewer: Raul Rangel <rrangel(a)chromium.org> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Attention: Konrad Adamczyk <konrada(a)google.com> Gerrit-Attention: Raul Rangel <rrangel(a)chromium.org> Gerrit-Attention: Jakub Czapiga <jacz(a)semihalf.com> Gerrit-Attention: Grzegorz Bernacki Gerrit-Comment-Date: Thu, 27 Apr 2023 00:38:07 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes Comment-In-Reply-To: Konrad Adamczyk <konrada(a)google.com> Comment-In-Reply-To: Raul Rangel <rrangel(a)chromium.org> Gerrit-MessageType: comment
