Hi, After talking a little bit with upstream about providing newer stable updates for Debian stable users I suggested that we could provide new upstream releases of mesa through jessie-backports. Then I found this existing thread requesting mesa for jessie-backports. So I'd be interested in backporting mesa to Jessie. I've already prepared backports of libdrm and mesa in [1] and [2]. The biggest change for backporting mesa is to build against llvm-3.5 instead of llvm-3.7. Thus it needs a few tweaks in debian/rules to disable llvmpipe on some archs and needs libclc from jessie. Furthermore mesa needs a newer libdrm backported from testing and needs to use the already backported libvdpau (thanks vcheng) from jessie- backports. Since I'm a DM I'd need a sponsor for the initial uploads of libdrm and mesa to BACKPORTS-NEW. I should be able to handle further uploads myself once my uid has been added into the backports ACL. Thanks, Andreas [1] https://anonscm.debian.org/cgit/pkg-xorg/lib/libdrm.git/log/?h=debian-jessie-backports [2] https://anonscm.debian.org/cgit/pkg-xorg/lib/mesa.git/log/?h=debian-jessie-backports
