Title: Radeon VDPAU clients crash at vlVdpDecoderCreate with 1080p videos Status in The Linux Kernel: Fix Released Status in “linux” package in Ubuntu: Triaged Bug description: I've enabled VDPAU support in flash player, and testing it with normal youtube videos (up to 720p) gives good results. However, once I switch to 1080p quality, the flash player crashes, and this happens at the mesa vdpau driver level because a Bus Error triggered by mesa since the CPU can't access properly to gpu VRAM. The same happens loading a 1080p video using VLC or MPlayer (see vlc backtrace http://paste.ubuntu.com/7405255/). Here's the problem as explained by Christian König: > It's not the VDPAU driver that's failing here, it's the kernel. > > When the kernel can't place a buffer into visible VRAM the buffer > should be moved into GART instead for CPU access. But instead we > just return a SIGBUS to the application effectively crashing it. I'm attaching the patch that fixes this problem, provided by Christian and tested successfully on ubuntu Trusty kernel.
