seeing VM_L2_PROTECTION_FAULT error and ring vcn_dec timeout because
of less dpb_size for VP9_2.

Jason Ekstrand 68092df8d8 intel/nir: Lower 8-bit ops to 16-bit in NIR on Gen11+
Intel hardware supports 8-bit arithmetic but it's tricky and annoying:

  - Byte operations don't actually execute with a byte type.  The
    execution type for byte operations is actually word.  (I don't know
    if this has implications for the HW implementation.  Probably?)

  - Destinations are required to be strided out to at least the
    execution type size.  This means that B-type operations always have
    a stride of at least 2.  This means wreaks havoc on the back-end in
    multiple ways.

  - Thanks to the strided destination, we don't actually save register
    space by storing things in bytes.  We could, in theory, interleave
    two byte values into a single 2B-strided register but that's both a
    pain for RA and would lead to piles of false dependencies pre-Gen12
    and on Gen12+, we'd need some significant improvements to the SWSB
    pass.

  - Also thanks to the strided destination, all byte writes are treated
    as partial writes by the back-end and we don't know how to copy-prop
    them.

  - On Gen11, they added a new hardware restriction that byte types
    aren't allowed in the 2nd and 3rd sources of instructions.  This
    means that we have to emit B->W conversions all over to resolve
    things.  If we emit said conversions in NIR, instead, there's a
    chance NIR can get rid of some of them for us.

We can get rid of a lot of this pain by just asking NIR to get rid of
8-bit arithmetic for us.  It may lead to a few more conversions in some
cases but having back-end copy-prop actually work is probably a bigger
bonus.  There is still a bit we have to handle in the back-end.  In
particular, basic MOVs and conversions because 8-bit load/store ops
still require 8-bit types.

Jason Ekstrand b98f0d3d7c intel/nir: Lower 8-bit scan/reduce ops to 16-bit
We can't really support these directly on any platform.  May as well let
NIR lower them.  The NIR lowering is potentially one more instruction
for scan/reduce ops thanks to not being able to do the B->W conversion
as part of SEL_EXEC.  For imax/imin exclusive scan, it's yet another
instruction thanks to the extra imax/imin NIR has to insert to deal with
the fact that the first live channel will contain the identity value
which, when signed, will cast wrong.  However, it does let us drop some
complexity from our back-end so it's probably worth it.

We forgot to initialize the sample_count member here, leading to it
being undefined. This causes problems on MSVC when compiling in
debug-mode, where we get a run-time error for using an undefined
variable.

To avoid similar problems in the future if more fields are added,
let's initialize the whole struct to zero to start with. This also
allows us to remove a no-longer-needed zero-initialization.

Krunal Patel 4143572f93 radeon/vcn: Bitrate not updated when changing framerate
Issue: Encoding parameters not updated after changing FrameRate

Root Cause:
In radeon_enc_begin_frame, there is a parameter need_rate_control
which was enabled only if the bitrate is changed. Due to this the
radeon_enc_rc_layer_init was not updating the encoder parameters with new
framerate, peak_bits_per_picture_integer and avg_target_bits_per_picture

Fix:
Added the condition where we will check if there is a change in
other parameters and enable rate control. Eventually updating the
encoder parameters with new framerate and bitrate.
