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 --- ...intel-haswell-make-IOMMU-a-runtime-option.patch | 292 +++++++++++++++++++++ 1 file changed, 292 insertions(+) create mode 100644 config/coreboot/default/patches/0034-nb-intel-haswell-make-IOMMU-a-runtime-option.patch (limited to 'config/coreboot/default/patches/0034-nb-intel-haswell-make-IOMMU-a-runtime-option.patch') diff --git a/config/coreboot/default/patches/0034-nb-intel-haswell-make-IOMMU-a-runtime-option.patch b/config/coreboot/default/patches/0034-nb-intel-haswell-make-IOMMU-a-runtime-option.patch new file mode 100644 index 00000000..ed6c0d65 --- /dev/null +++ b/config/coreboot/default/patches/0034-nb-intel-haswell-make-IOMMU-a-runtime-option.patch @@ -0,0 +1,292 @@ +From eef3e0d517bde40d4761a9af3c004801a89db887 Mon Sep 17 00:00:00 2001 +From: Leah Rowe +Date: Sat, 2 Mar 2024 22:51:09 +0000 +Subject: [PATCH 34/39] nb/intel/haswell: make IOMMU a runtime option + +When I tested graphics cards on a coreboot port for Dell +OptiPlex 9020 SFF, I could not use a graphics card unless +I set iommu=off on the Linux cmdline. + +Coreboot's current behaviour is to check whether the CPU +has vt-d support and, if it does, initialise the IOMMU. + +This patch maintains the current behaviour by default, but +allows the user to turn *off* the IOMMU, even if vt-d is +supported by the host CPU. + +If iommu=Disable is specified, the check will not be +performed, and the IOMMU will be left disabled. This option +has been added to all current Haswell boards, though it is +recommended to leave the IOMMU turned on in most setups. + +Signed-off-by: Leah Rowe +--- + src/mainboard/asrock/b85m_pro4/cmos.default | 1 + + src/mainboard/asrock/b85m_pro4/cmos.layout | 3 +++ + src/mainboard/asrock/h81m-hds/cmos.default | 1 + + src/mainboard/asrock/h81m-hds/cmos.layout | 6 ++++++ + src/mainboard/dell/optiplex_9020/cmos.default | 1 + + src/mainboard/dell/optiplex_9020/cmos.layout | 6 ++++++ + src/mainboard/google/beltino/cmos.layout | 5 +++++ + src/mainboard/google/slippy/cmos.layout | 5 +++++ + src/mainboard/intel/baskingridge/cmos.layout | 4 ++++ + src/mainboard/lenovo/haswell/cmos.default | 1 + + src/mainboard/lenovo/haswell/cmos.layout | 3 +++ + src/mainboard/supermicro/x10slm-f/cmos.default | 1 + + src/mainboard/supermicro/x10slm-f/cmos.layout | 6 ++++++ + src/northbridge/intel/haswell/early_init.c | 5 +++++ + 14 files changed, 48 insertions(+) + +diff --git a/src/mainboard/asrock/b85m_pro4/cmos.default b/src/mainboard/asrock/b85m_pro4/cmos.default +index 01bf20ad16..dfc8b80fb0 100644 +--- a/src/mainboard/asrock/b85m_pro4/cmos.default ++++ b/src/mainboard/asrock/b85m_pro4/cmos.default +@@ -4,3 +4,4 @@ boot_option=Fallback + debug_level=Debug + nmi=Enable + power_on_after_fail=Disable ++iommu=Enable +diff --git a/src/mainboard/asrock/b85m_pro4/cmos.layout b/src/mainboard/asrock/b85m_pro4/cmos.layout +index efdc333fc2..c9883ea71d 100644 +--- a/src/mainboard/asrock/b85m_pro4/cmos.layout ++++ b/src/mainboard/asrock/b85m_pro4/cmos.layout +@@ -11,6 +11,7 @@ + 395 4 e 4 debug_level + 408 1 e 1 nmi + 409 2 e 5 power_on_after_fail ++ 412 1 e 6 iommu + 984 16 h 0 check_sum + #
