Probably a typo.. we obviously need "(bpp + 7) / 8" instead of "(bpp + 1) / 8". Unlikely to be hit in any sane code, but lets be safe. Use DIV_ROUND_UP() to avoid the problem entirely and make the core more readable. Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: David Herrmann <dh.herrmann@gmail.com>

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.

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: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>

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

This is a superset of the current i2c_dp_aux bus functionality and can be used to transfer native AUX in addition to I2C-over-AUX messages. Helpers are provided to read and write the DPCD, either blockwise or byte-wise. Many of the existing helpers for DisplayPort take a copy of a portion of the DPCD and operate on that, without a way to write data back to the DPCD (e.g. for configuration of the link). Subsequent patches will build upon this infrastructure to provide common functionality in a generic way.
