Patch Set 13: (2 comments) Patchset: PS10: > ` Ack File flashrom.c: https://review.coreboot.org/c/flashrom/+/71119/comment/4b479c5d_340910ad PS12, Line 37: use_legacy_erase_path > `use_legacy_erase_path` is not modified anywhere. […] You _could_ add it as a build flag however this is easy enough to toggle with a one-line commit too. I believe Thomas is catching up on email however he could perhaps help advise with working towards making the new algorithm the default. My suggestion once you have your work landed on HEAD is to send a email to the mailing list/IRC channel and try to engage some folks to help with testing. The other part is to try and build up the portfolio of unit-test coverage around this new algorithm that instrument the fundamental data structures and procedures mapped over them at play here. Furthermore the unit-tests will help mature not just the functional code quality but also the code structure. -- To view, visit https://review.coreboot.org/c/flashrom/+/71119 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: Ib5660db0067c1c799dcb5c8e83b4a4826b236442 Gerrit-Change-Number: 71119 Gerrit-PatchSet: 13 Gerrit-Owner: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Reviewer: Aarya <aarya.chaumal(a)gmail.com> Gerrit-Reviewer: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Reviewer: Felix Singer <felixsinger(a)posteo.net> Gerrit-Reviewer: Thomas Heijligen <src(a)posteo.de> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Attention: Felix Singer <felixsinger(a)posteo.net> Gerrit-Attention: Thomas Heijligen <src(a)posteo.de> Gerrit-Attention: Aarya <aarya.chaumal(a)gmail.com> Gerrit-Comment-Date: Thu, 26 Jan 2023 07:52:36 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Edward O'Callaghan <quasisec(a)chromium.org> Comment-In-Reply-To: Aarya <aarya.chaumal(a)gmail.com> Gerrit-MessageType: comment

If there is any combination of buses that is not covered by unit test, it can be added, can be added in this patch. And then the best thing is: unit tests can fully test this patch! and unit tests are checking there is no memory leaks. -- To view, visit https://review.coreboot.org/c/flashrom/+/72408 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I0c67c25b0f53cd8c564c4ea0f09f2728e856f6ea Gerrit-Change-Number: 72408 Gerrit-PatchSet: 2 Gerrit-Owner: Alexander Goncharov <chat(a)joursoir.net> Gerrit-Reviewer: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Attention: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Attention: Alexander Goncharov <chat(a)joursoir.net> Gerrit-Comment-Date: Wed, 25 Jan 2023 10:34:58 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Gerrit-MessageType: comment
