It seems like if we can assume ECAM is always available on the relevant systems and it's less prone to bugs caused by libpci interacting poorly with OS-level drivers accessing the same hardware, then we should use ECAM as long as it's supported by the version of libpci in use and don't need this option. -- To view, visit https://review.coreboot.org/c/flashrom/+/83896?usp=email To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: flashrom Gerrit-Branch: main Gerrit-Change-Id: I4549f87c8b01da0a1d3d8ce0b3b75c1f5fa2cbab Gerrit-Change-Number: 83896 Gerrit-PatchSet: 3 Gerrit-Owner: Kane Chen <kane.chen(a)intel.com> Gerrit-Reviewer: Hsuan Ting Chen <roccochen(a)chromium.org> Gerrit-Reviewer: Hsuan-ting Chen <roccochen(a)google.com> Gerrit-Reviewer: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Reviewer: Subrata Banik <subratabanik(a)google.com> Gerrit-CC: Kane Chen <kane.chen(a)intel.corp-partner.google.com> Gerrit-Attention: Hsuan Ting Chen <roccochen(a)chromium.org> Gerrit-Attention: Hsuan-ting Chen <roccochen(a)google.com> Gerrit-Attention: Kane Chen <kane.chen(a)intel.com> Gerrit-Comment-Date: Fri, 16 Aug 2024 03:42:28 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No
