From d70c553b32b6381843e6bf5277d54541e368c3a1 Mon Sep 17 00:00:00 2001 From: Jamie McClymont Date: Fri, 2 Apr 2021 09:04:16 +0000 Subject: chromiumOSPackages: 83.13020.0.0-rc1 -> 89.13729.0.0-rc1 * chromiumOSPackages.linux: fix config * chromiumOSPackages.common-mk: update patches * chromiumOSPackages.vm_protos: drop GN patch The missing dependency has been added upstream. * chromiumOSPackages.common-mk: disable clang-only warnings * chromiumOSPackages.sommelier: update patches Support for stable xdg-shell was implemented in upstream Sommelier, but then reverted because the GTK version that comes with the Debian in the container Chromium OS uses was too old to support it. That's not a problem for us, of course, but it does mean that we can use an upstream implementation of xdg-shell. So here I switch from using Puck's implementation, to reverting the revert of the upstream one. * crosvm: fix outdated Cargo.lock from upstream * crosvm: update VIRTIO_NET_F_MAC patch (renamed to be less annoying) * crosvm: add new dependencies * crosvm: patch boot test so it doesn't fail because of no /dev/log. * crosvm: disable boot test on x86_64 because it often hangs on the AMD EPYC 7401P 24-Core Processor I was testing it on (but not my Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz). * spectrumPackages.linux: drop evged patch This has reached the Chromium OS kernel now, so we don't need to apply it ourselves any more.
