From dbe24b039d381365b62c02802016f108c3efe8eb Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Wed, 31 Jul 2024 12:26:25 +0100 Subject: coreboot/default: Update to 97bc693ab (2024-07-29) Several patches are now merged upstream and no longer needed in lbmk, such as the HP EliteBook 8560w patch, and related patches. Some patches were changed, for example the Dell Latitude ivb/snb laptops are now variants in coreboot, instead of being individual ports; now they re-use the same base code. This this, the corresponding files under config/submodules have changed, for things like 3rdparty submodules e.g. libgfxinit, and tarballs e.g. crossgcc. This is long overdue, and will enable more boards to be added. This newer revision will be used in the next release, and some follow-up patches will merge these trees into default: * coreboot/haswell * coreboot/dell Signed-off-by: Leah Rowe --- ...ll-optiplex_9020-Disable-IOMMU-by-default.patch | 29 ++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 config/coreboot/default/patches/0035-dell-optiplex_9020-Disable-IOMMU-by-default.patch (limited to 'config/coreboot/default/patches/0035-dell-optiplex_9020-Disable-IOMMU-by-default.patch') diff --git a/config/coreboot/default/patches/0035-dell-optiplex_9020-Disable-IOMMU-by-default.patch b/config/coreboot/default/patches/0035-dell-optiplex_9020-Disable-IOMMU-by-default.patch new file mode 100644 index 00000000..1b9497c2 --- /dev/null +++ b/config/coreboot/default/patches/0035-dell-optiplex_9020-Disable-IOMMU-by-default.patch @@ -0,0 +1,29 @@ +From b7a80abe673c279e755efbe92851ec0600467fae Mon Sep 17 00:00:00 2001 +From: Leah Rowe +Date: Sat, 2 Mar 2024 23:00:09 +0000 +Subject: [PATCH 35/39] dell/optiplex_9020: Disable IOMMU by default + +Needed to make graphics cards work.
