5bbde9b80f anv: Fix close(fd) before import issue in vkCreateDmaBufImageINTEL
If we close the fd before calling DRM_IOCTL_PRIME_FD_TO_HANDLE the kernel
will hit a -EBADF error. Move the close(fd) call to the end of
anv_CreateDmaBufImageINTEL().

78c18d99dc intel: gen-decoder: print all dword a field belongs to
Prior to printing a decoded field, print out all dwords that field
belongs to. In particular with address fields spanning multiple
dwords, we want to have all the dwords presented before the field is
decoded to make it easier to read.

4d59127213 intel: genxml: decode variable length MI_LRI
MI_LOAD_REGISTER_IMM can load multiple (register, value) tuples in one
command. In our drivers we only use one tuple at a time, but the
kernel might load more than one at a time.

Instead of making all the tuple part of a group, we leave out the
first tuple (the one we use in the generated packing structures).

This is particularly useful for looking at error stats generated by
the kernel.

81375516b2 intel: error_decode: add an option to decode all buffers
The kernel reports workaround batch buffers, but we're not presenting
them currently. Also they might not be useful for debugging purely
userspace driver issues, when problems arise because of interactions
between kernel & userspace drivers, it's nice to be able to decode
them.

f60c5fc17e anv/cmd_buffer: consider multiview masks for tracking pending clear aspects
When multiview is active a subpass clear may only clear a subset of the
attachment layers. Other subpasses in the same render pass may also
clear too and we want to honor those clears as well, however, we need to
ensure that we only clear a layer once, on the first subpass that uses
a particular layer (view) of a given attachment.

This means that when we check if a subpass attachment needs to be cleared
we need to check if all the layers used by that subpass (as indicated by
its view_mask) have already been cleared in previous subpasses or not, in
which case, we must clear any pending layers used by the subpass, and only
those pending.

v2:
  - track pending clear views in the attachment state (Jason)
  - rebased on top of fast-clear rework.

v3:
  - rebased on top of subpass rework.

v4: rebased.

v5 (Caio):
 - Rebased.
 - Initialize pending clear views to only have bits set for layers
   that exist.
 - Reset pending clear views in one go rather one bit at a time.
 - Put "last subpass for this attachment" condition in a separate
   function to simplify the conditional that resets pending_clear_aspects.

91225cb33f i965/vec4: Fix null destination register in 3-source instructions
A recent commit (see below) triggered some cases where conditional
modifier propagation and dead code elimination would cause a MAD
instruction like the following to be generated:

    mad.l.f0  null, ...

Matt pointed out that fs_visitor::fixup_3src_null_dest() fixes cases
like this in the scalar backend.  This commit basically ports that code
to the vec4 backend.

NOTE: I have sent a couple tests to the piglit list that reproduce this
bug *without* the commit mentioned below.  This commit fixes those
tests.

020b0055e7 i965/fs: Propagate conditional modifiers from compares to adds
The math inside the add and the cmp in this instruction sequence is the
same.  We can utilize this to eliminate the compare.

add(8)          g5<1>F          g2<8,8,1>F      g64.5<0,1,0>F   { align1 1Q compacted };
cmp.z.f0(8)     null<1>F        g2<8,8,1>F      -g64.5<0,1,0>F  { align1 1Q switch };
(-f0) sel(8)    g8<1>F          (abs)g5<8,8,1>F 3e-37F          { align1 1Q };

This is reduced to:

add.z.f0(8)     g5<1>F          g2<8,8,1>F      g64.5<0,1,0>F   { align1 1Q compacted };
(-f0) sel(8)    g8<1>F          (abs)g5<8,8,1>F 3e-37F          { align1 1Q };

This optimization pass could do even better.  The nature of converting
vectorized code from the GLSL front end to scalar code in NIR results in
sequences like:

add(8)          g7<1>F          g4<8,8,1>F      g64.5<0,1,0>F   { align1 1Q compacted };
add(8)          g6<1>F          g3<8,8,1>F      g64.5<0,1,0>F   { align1 1Q compacted };
add(8)          g5<1>F          g2<8,8,1>F      g64.5<0,1,0>F   { align1 1Q compacted };
cmp.z.f0(8)     null<1>F        g2<8,8,1>F      -g64.5<0,1,0>F  { align1 1Q switch };
(-f0) sel(8)    g8<1>F          (abs)g5<8,8,1>F 3e-37F          { align1 1Q };
cmp.z.f0(8)     null<1>F        g3<8,8,1>F      -g64.5<0,1,0>F  { align1 1Q switch };
(-f0) sel(8)    g10<1>F         (abs)g6<8,8,1>F 3e-37F          { align1 1Q };
cmp.z.f0(8)     null<1>F        g4<8,8,1>F      -g64.5<0,1,0>F  { align1 1Q switch };
(-f0) sel(8)    g12<1>F         (abs)g7<8,8,1>F 3e-37F          { align1 1Q };

In this sequence, only the first cmp.z is removed.  With different
scheduling, all 3 could get removed.

This method is similar to the existing ::equals methods.  Instead of

the negation of the other.

v2: Simplify various checks based on suggestions from Matt.  Use
src_reg::type instead of fixed_hw_reg.type in a check.  Also suggested
by Matt.

v3: Rebase on 3 years.  Fix some problems with negative_equals with VF
constants.  Add fs_reg::negative_equals.

v4: Replace the existing default case with BRW_REGISTER_TYPE_UB,
BRW_REGISTER_TYPE_B, and BRW_REGISTER_TYPE_NF.  Suggested by Matt.

57a11550bc i965: perf: query topology
With the introduction of asymmetric slices in CNL, we cannot rely on
the previous SUBSLICE_MASK getparam to tell userspace what subslices
are available.

We introduce a new uAPI in the kernel driver to report exactly what
part of the GPU are fused and require this to be available on Gen10+.

Prior generations can continue to rely on GETPARAM on older kernels.

This patch is quite a lot of code because we have to support lots of
different kernel versions, ranging from not providing any information
(for Haswell on 4.13 through 4.17), to being able to query through
GETPARAM (for gen8/9 on 4.13 through 4.17), to finally requiring 4.17
for Gen10+.

This change stores topology information in a unified way on
brw_context.topology from the various kernel APIs. And then generates
the appropriate values for the equations from that unified topology.

v2: Move slice/subslice masks fields to gen_device_info (Rafael)

v3: Add a gen_device_info_subslice_available() helper (Lionel)

c1900f5b0f intel: devinfo: add helper functions to fill fusing masks values
There are a couple of ways we can get the fusing information from the
kernel :

  - Through DRM_I915_GETPARAM with the SLICE_MASK/SUBSLICE_MASK
    parameters

  - Through the new DRM_IOCTL_I915_QUERY by requesting the
    DRM_I915_QUERY_TOPOLOGY_INFO

The second method is more accurate and also gives us the EUs fusing
masks. It's also a requirement for CNL as this platform has asymetric
subslices and the first method SUBSLICE_MASK value is assumed uniform
across slices.

5e7c1d05d4 anv/pipeline: use less instructions for multiview
The view_index is encoded in the remainder of dividing instance id by
the number of views in the view mask (n). In the general case (handled
by the else clause), there is a need to map from 0..n-1 into the
number of the view being masked. For that a map is encoded.

In the case only the first n bits in the mask are set, the mapping is
trivial, 0..n-1 already represent what view is being referred to.

That case was in the original patch that added
anv_nir_lower_multiview.c but disabled.
