Priority: medium
Bug ID: 73507
Assignee: chris at chris-wilson.co.uk
Summary: intel xorg driver does not support DRI2DriverVDPAU
name
QA Contact: intel-gfx-bugs at lists.freedesktop.org
Severity: enhancement
Classification: Unclassified
OS: All
Reporter: ibragimovrinat at mail.ru
Hardware: Other
Status: NEW
Version: unspecified
Component: Driver/intel
Product: xorg
Since 2010, DRI2 supports multiple driver names. That was added to ease
selection of appropriate driver by libvdpau. As for today, intel driver
support only DRI2DriverDRI (== 0), but not DRI2DriverVDPAU (== 1).
Although there is no any hardware-specific VDPAU driver for intel video
adapters at the moment, it would be easier to use generic drivers like
libvdpau-va-gl by creating symlink named libvdpau_i965.so.1. That way
appropriate driver will be selected in run time automatically:
libvdpau_i965.so.1 on i965 equipped machines, and libvdpau_nvidia.so.1 on
nvidia equipped ones.
