Userspace should set the first 4 bits of drm_radeon_cs_reloc::flags to a number from 0 to 15. The higher the number, the higher the priority, which means a buffer with a higher number will be validated sooner. The old behavior is preserved: Buffers used for write are prioritized over read-only buffers if the userspace doesn't set the number. v2: add buffers to buckets directly, then concatenate them v3: use a stable sort Signed-off-by:

The statistics are: - VRAM usage in bytes - GTT usage in bytes - number of bytes moved by TTM The last one is actually a counter, so you need to sample it before and after command submission and take the difference. This is useful for finding performance bottlenecks. Userspace queries are also added. v2: use atomic64_t Signed-off-by:

Now that Christian fixed the performance problems with the feedback buffer in mesa, we can enable variable UVD clocks. There are multiple UVD power states associated with different types and numbers of streams. This uses the appropriate state based on that information rather than always using the fastest UVD clocks which saves some power. One possible downside is that this may adversely affect decode benchmarks since these power states target specific playback requirements rather than maximum performance. If that becomes an issue, we can add a sysfs attribute to force the max UVD state. Signed-off-by:

Updates from Jean-Fracois for the TDA998x driver, which are on top of the fixes you have previously pulled, except these changes aren't intended for -rc, but the next merge window. Several of these are issues of correctness - passing more correct HDMI info packets, not reading registers in older chips documented as write only (despite appearing to be read/write in later chips). Others are code cleanups (using definitions rather than constants where we have them already in the kernel). Additional functionality is also added by way of optional support for the IRQ from the TDA998x, which allows us to avoid busy-waiting for the EDID reads. * 'tda998x-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-cubox: drm/i2c: tda998x: always use the same device for all kernel messages drm/i2c: tda998x: adjust the audio clock divider for S/PDIF drm/i2c: tda998x: code optimization drm/i2c: tda998x: remove the unused variable ca_i2s drm/i2c: tda998x: make the audio code more readable drm/i2c: tda998x: use irq for connection status and EDID read drm/i2c: tda998x: always enable EDID read IRQ drm/i2c: tda998x: add DT documentation drm/i2c: tda998x: add DT support drm/i2c: tda998x: don't read write-only registers drm/i2c: tda998x: don't freeze the system at audio startup time drm/i2c: tda998x: change probe message origin drm/i2c: tda998x: code cleanup drm/i2c: tda998x: clean up error chip version checking drm/i2c: tda998x: check more I/O errors drm/i2c: tda998x: simplify the i2c read/write functions drm/i2c: tda998x: use ALSA IEC958 definitions and update audio frequency drm/i2c: tda998x: add the active aspect in HDMI AVI frame drm/i2c: tda998x: use HDMI constants
