Package: src:mesa
Severity: normal
Dear Maintainer,
SWR is a new high performance rasterizer that is usually significantly
faster than softpipe or llvmpipe and is merged in upstream Mesa for
some time.
Adding these meson extra flags:
"-Dgallium-drivers=....,swrast,swr" "-Dswr-arches=avx,avx2,knl,skx"
should build and install these files in lib/{x86_64,i386}-linux-gnu/
libswrAVX2.so
libswrAVX2.so.0
libswrAVX2.so.0.0.0
libswrAVX.so
libswrAVX.so.0
libswrAVX.so.0.0.0
libswrKNL.so
libswrKNL.so.0
libswrKNL.so.0.0.0
libswrSKX.so
libswrSKX.so.0
libswrSKX.so.0.0.0
dri/kms_swrast_dri.so (maybe)
dri/swrast_dri.so
It is probably worth packaging into separate package (with all arches
tho, no need to split it into 4 packages, mesa gallium loaader will
automatically determine best suitable version and load it dynamically).
Building on other archs might succeed (unlikely), but it is pointless as
SWR targets at the moment only x86 specific vector instructions so even if
it manages to be able to generate code at runtime (via LLVM) it will not be
able to run it anyway. Thus the request is only for i386 and amd64.
Adding x32 and kfreebsd-{amd64,i386} at your discretion.
Best regards,
Witold.
