From: Randolph Sapp <[email protected]> Meta-clang provides a bbappend for mesa to use clang to accelerate it's rasterization with runtime code generation through the use of llvmpipe. With the addition of mesa-pvr we no longer get this for free with the blanket mesa bbappend on the devices that explicitly request mesa-pvr so lets add a dynamic layer to append the same args meta-clang does.
Though the number of devices that would select pvr-mesa and still want to use software rendering is small, it's not zero due to debug and testing purposes. Signed-off-by: Randolph Sapp <[email protected]> --- Please let me know if I'm overlooking some specification like some reason bsp layers shouldn't have dynamic-layers or something like that. The yocto-check-layer didn't seem to care. meta-ti-bsp/conf/layer.conf | 4 ++++ .../recipes-graphics/mesa/mesa-pvr_%.bbappend | 14 ++++++++++++++ 2 files changed, 18 insertions(+) create mode 100644 meta-ti-bsp/dynamic-layers/clang-layer/recipes-graphics/mesa/mesa-pvr_%.bbappend diff --git a/meta-ti-bsp/conf/layer.conf b/meta-ti-bsp/conf/layer.conf index 26cbb4b5..56ca392b 100644 --- a/meta-ti-bsp/conf/layer.conf +++ b/meta-ti-bsp/conf/layer.conf @@ -18,6 +18,10 @@ LAYERDEPENDS_meta-ti-bsp = " \ meta-arm \ " +BBFILES_DYNAMIC += " \ + clang-layer:${LAYERDIR}/dynamic-layers/clang-layer/recipes*/*/*.bbappend \ +" + SIGGEN_EXCLUDERECIPES_ABISAFE += " \ mesa-pvr \ " diff --git a/meta-ti-bsp/dynamic-layers/clang-layer/recipes-graphics/mesa/mesa-pvr_%.bbappend b/meta-ti-bsp/dynamic-layers/clang-layer/recipes-graphics/mesa/mesa-pvr_%.bbappend new file mode 100644 index 00000000..7e5c36fd --- /dev/null +++ b/meta-ti-bsp/dynamic-layers/clang-layer/recipes-graphics/mesa/mesa-pvr_%.bbappend @@ -0,0 +1,14 @@ +# This is a copy of meta-clang/recipes-graphics/mesa/mesa_%.bbappend required +# for llvmpipe when using pvr-mesa since we aren't caught by that glob. + +FILESEXTRAPATHS:prepend := "${THISDIR}/${PN}:" + +LDFLAGS:append:toolchain-clang = " -latomic -lm" +DEPENDS:append:toolchain-clang = " libatomic-ops" + +EXTRA_OEMASON:append:toolchain-clang:x86 = " -Dasm=false" +EXTRA_OEMASON:append:toolchain-clang:x86-64 = " -Dasm=false" + +export YOCTO_ALTERNATE_EXE_PATH = "${STAGING_LIBDIR}/llvm-config" + +PACKAGECONFIG[gallium-llvm] = "-Dllvm=true -Dshared-llvm=true -Ddraw-use-llvm=true,-Dllvm=false,clang clang-native elfutils" -- 2.41.0
