radv: save/restore all viewports/scissors for meta operations

This is needed since we don't update the number of viewports/scissors
when they are set dynamically (according to the spec). In the following
scenario:

* vkCmdSetViewport()
* vkCmdClearColorImage() (or any other meta operations)

The viewports/scissors weren't saved correctly because no pipeline
was bound before, and thus the number of viewports/scissors were 0.

This fixes a regression with:

dEQP-VK.draw.negative_viewport_height.front_ccw_cull_back

formats introduced by VK_IMG_format_pvrtc :

VK_FORMAT_ASTC_10x8_UNORM_BLOCK = 177,

VK_FORMAT_ASTC_12x10_SRGB_BLOCK = 182,
VK_FORMAT_ASTC_12x12_UNORM_BLOCK = 183,
VK_FORMAT_ASTC_12x12_SRGB_BLOCK = 184,
VK_FORMAT_PVRTC1_2BPP_UNORM_BLOCK_IMG = 1000054000,
VK_FORMAT_PVRTC1_4BPP_UNORM_BLOCK_IMG = 1000054001,

VK_FORMAT_PVRTC2_4BPP_SRGB_BLOCK_IMG = 1000054007,

It's obvious we can't have a single table for handling those anymore.

Fortunately the enum values actually contain the number of the
extension that introduced the new enums. So we can build an
indirection table off the extension number and then index by
subtracting the first enum of the the format enum value.

i965: Fix brw_finish_batch to grow the batchbuffer.

brw_finish_batch emits commands needed at the end of every batch buffer,
including any workarounds.  In the past, we freed up some "reserved"
batch space before calling it, so we would never have to flush during
it.  This was error prone and easy to screw up, so I deleted it a while
back in favor of growing the batch.

There were two problems:

1. We're in the middle of flushing, so brw->no_batch_wrap is guaranteed
   not to be set.  Using BEGIN_BATCH() to emit commands would cause a
   recursive flush rather than growing the buffer as intended.

2. We already recorded the throttling batch before growing, which
   replaces brw->batch.bo with a different (larger) buffer.  So growing
   would break throttling.

These are easily remedied by shuffling some code around and whacking
brw->no_batch_wrap in brw_finish_batch().  This also now includes the
final workarounds in the batch usage statistics.  Found by inspection.

anv/image: Use RENDER_SURFACE_STATE::X/Y Offset on SKL+

The Broadwell method of handling uncompressed views of compressed
textures was to make the texture linear and have a tiled shadow copy.
This isn't needed on Sky Lake because the HALIGN and VALIGN parameters
are specified in surface elements and required to be a multiple of 4.
This means that we can just use the X/Y Offset fields and we can avoid
the shadow copy song and dance.  This also makes ASTC work because ASTC
can't be linear and so the shadow copy method doesn't work there.

anv/image: Support creating uncompressed views of compressed images

In order to get support everywhere, this gets a bit complicated.  On Sky
Lake and later, everything is fine because HALIGN/VALIGN are specified
in surface elements and are required to be at least 4 so any offsetting
we may need to do falls neatly within the heavy restrictions placed on
the X/Y Offset parameter of RENDER_SURFACE_STATE.  On Broadwell and
earlier, HALIGN/VALIGN are specified in pixels and are hard-coded to
align to exactly the block size of the compressed texture.  This means
that, when reinterpreted as a non-compressed texture, the tile offsets
may be anything and we can't rely on X/Y Offset.

In order to work around this issue, we fall back to linear where we can
trivially offset to whatever element we so choose.  However, since
linear texturing performance is terrible, we create a tiled shadow copy
of the image to use for texturing.  Whenever the user does a layout
transition from anything to SHADER_READ_ONLY_OPTIMAL, we use blorp to
copy the contents of the texture from the linear copy to the tiled
shadow copy.  This assumes that the client will use the image far more
for texturing than as a storage image or render target.

Even though we don't need the shadow copy on Sky Lake, we implement it
this way first to make testing easier.  Due to the hardware restriction
that ASTC must not be linear, ASTC does not work yet.

anv: Add a new anv_surface_state struct

This struct represents a full surface state including the addresses of
the referenced main and auxiliary surfaces (if any).  This makes
relocation setup substantially simpler and allows us to move 100% of the

were manually fishing data out of surface states when emitting
relocations so we knew how to offset aux address.  It's best to keep all
of the surface state emit logic together.  This also gets us closer, at

llvmpipe, gallivm: implement lod queries (LODQ opcode)

This uses all the existing code to calculate lod values for mip linear
filtering. Though we'll have to disable the simplifications (if we know some
parts of the lod calculation won't actually matter for filtering purposes due
to mip clamps etc.). For better or worse, we'll also disable lod calculation
hacks (mostly should make a difference for cube maps) always - the issue with
per-pixel lod being difficult is mostly because we then have different mipmaps
needed for the actual texel fetch, which isn't a problem with lodq.
We still use approximation for the log2 - for that reason I believe the float
part of the lod is only accurate to about 4-5 bits (and one bit less with 1d
textures actually) which is hopefully good enough (though d3d10 technically
requires 6 bits - could use quadratic interpolation instead of linear to get
8 bits or so).
Since lodq requires unclamped lod, we also have to move some sampler key
calculations to texture sampling code - even if we know we're going to access
mipmap 0 we still have to calculate lod and apply lod_bias for lodq.
