Change in coreboot[master]: soc/intel/crashlog: Temporarily remove to reorganize
by Tim Wawrzynczak (Code Review) 03 Feb '22

03 Feb '22

Attention is currently required from: Patrick Rudolph. Tim Wawrzynczak has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/61602 ) Change subject: soc/intel/crashlog: Temporarily remove to reorganize ...................................................................... soc/intel/crashlog: Temporarily remove to reorganize Since there is some copy-pasting between the ADL and TGL drivers, a refactoring would be helpful. In addition, the drivers are a great candidate for becoming coreboot PCI drivers based on the CRASHLOG and SRAM PCI devices. In order to ease review of the final patches, and the final flow, this patch removes the current crashlog code, which will be reintroduced in different places in the following patches.

Change in coreboot[master]: device: Add pciexp_find_next_extended_cap function
by Tim Wawrzynczak (Code Review) 03 Feb '22

03 Feb '22

Attention is currently required from: Francois Toguo Fotso, Tim Wawrzynczak, Karthik Ramasubramanian. Hello build bot (Jenkins), Francois Toguo Fotso, Furquan Shaikh, Paul Menzel, Nick Vaccaro, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/coreboot/+/57784 to look at the new patch set (#3). Change subject: device: Add pciexp_find_next_extended_cap function ...................................................................... device: Add pciexp_find_next_extended_cap function Some PCIe devices have extended capability lists that contain multiples instances of the same capability. This patch provides a function similar to pciexp_find_extended_cap that can be used to search through multiple instances of the same capability by returning the offset of the next extended capability of the given type following the passed-in offset. The base functionality of searching for a given capability from an offset is extracted to a local helper function and both pciexp_find_extended_cap and pciexp_find_next_extended_cap use this helper.

Change in coreboot[master]: [only for test] test gcc-12 snapshot
by Martin Roth (Code Review) 03 Feb '22

Attention is currently required from: HAOUAS Elyes. Martin Roth has posted comments on this change. ( https://review.coreboot.org/c/coreboot/+/61533 ) Change subject: [only for test] test gcc-12 snapshot ...................................................................... Patch Set 3: (1 comment) Patchset: PS3: > any way... […] Yeah, we probably need to add an updated gnat version. I think that testing pre-releases is actually really useful to help us see what issues we might be running into. It might be worth setting up a separate build just to test pre-release/just-released toolchains. It'd be good to get them tested on real hardware somehow too. -- To view, visit https://review.coreboot.org/c/coreboot/+/61533 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: coreboot Gerrit-Branch: master Gerrit-Change-Id: I2545f4119a20eec6482fbdf8993eb842af96a0a7 Gerrit-Change-Number: 61533 Gerrit-PatchSet: 3 Gerrit-Owner: HAOUAS Elyes <ehaouas(a)noos.fr> Gerrit-Reviewer: Martin Roth <martinroth(a)google.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Attention: HAOUAS Elyes <ehaouas(a)noos.fr> Gerrit-Comment-Date: Thu, 03 Feb 2022 20:50:46 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Martin Roth <martinroth(a)google.com> Comment-In-Reply-To: HAOUAS Elyes <ehaouas(a)noos.fr> Gerrit-MessageType: comment
