Hi everyone, Some time ago I sent patches to enable the swrast driver on GBM/DRM, and I did them in the dumbest way possible (that is, having GBM implement the dri-swrast interface), to make sure it would work without kernel support. This patch series is a little smarter, in that it creates more than one KMS buffer and has llvmpipe render directly into the KMS buffer, so we don't need to copy from the back to the shadow (before the kernel copies from the shadow to the front).
For background, this is necessary to get mutter-wayland running inside VMs such as gnome-continuous, which has a qxl DRM driver. mutter-wayland only has a KMS/EGL rendering backend, and we have no intention to add pixman or fbdev. GNOME bug: https://bugzilla.gnome.org/show_bug.cgi?id=728059 The older patches were http://lists.freedesktop.org/archives/mesa-dev/2014-March/055113.html I can rebase if so is desired. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
