...w to determine what happens to the packet afterwards. Is there a Dtrace script that follows a packet queued bia send(2) or sendto(2) through the kernel/stack and can indicate whether some low-level function returns a failure, or possibly hands it to a different interface (we snooped all except the unsnoopable lo though w/o luck).. I looked at the Dtrace Networking Guide but without more knowledge of internals it was no help. PS: The Solaris-10 machine I work on is old, so it has no ip nor udp provider, but if it takes that I''d also like to know. any hints on where to start would be welcome.

This flag allows userspace to give the kernel a hint that it should use a non-snooped resource. To guarantee coherency at all times mappings into userspace are done write combined, so userspace should avoid reading back from those resources.

This is the first set of patches to make Nouveau work on Tegra. Those are only the obvious correctness fixes, a lot of optimization work remains to be done, but at least it's enough to get accel working and let the machine survive a piglit run. A new BO flag is introduced to allow userspace to hint the kernel about possible optimizations. Lucas Stach (6): drm/ttm: recognize ARM arch in

The last couple of weeks have been fairly retrospective, a dive into prehistory tidying up the earlier generations which lay languishing as the core progressed and lead to a number of annoying core bugs being fixed. -Chris * Release DRM master earlier during shutdown so switching between multiple X servers works automatically. https://bugs.freedesktop.org/show_bug.cgi?id=55446 * Suppress

Unfortunately AGP is still to widely used as we could just drop support for using its GART. Not using the AGP GART also doesn't mean a loss in functionality since drivers will just fallback to the driver specific PCI GART. For now just deprecate the code and don't enable the AGP GART in TTM even when general AGP support is available. Please comment, Christian.
