Adam Jackson 768238fdc0 glx: Fix drawable refcounting for naked Windows
driFetchDrawable is only ever called from the MakeCurrent path, which
means it has to handle the case of pre-GLX-1.3 Windows being named as
the drawable. When it finds the drawable in the hash, it increments its
refcount before returning it, so for a GLXWindow it would be 2 on first
return, one from glXCreateWindow and one from glXMakeCurrent. But when
it does not find the drawable and creates one for the naked Window, the
reference count on first return would only be 1. As a result, if this
context was then ever bound to a different drawable, the old Window's
DRI drawable state (like the back buffer) would be destroyed.

Fixes piglit's glx-multi-window-single-context and glx-make-current for
a variety of drivers.

Danylo Piliaiev bf4c160909 tu: Fix prim gen query and pipeline stats query interaction
Fixed:
- VK_QUERY_TYPE_PRIMITIVES_GENERATED_EXT was able to stop prim counter
  when pipeline stats query is running.
  - This may have happened when prim gen query was in secondary cmdbuf.
- VK_QUERY_TYPE_PRIMITIVES_GENERATED_EXT counting geometry in each tile.
- VK_QUERY_TYPE_PRIMITIVES_GENERATED_EXT counting geometry in each tile
  when pipeline stats query is started inside prim gen query and inside
  a renderpass.

The matter of VK_QUERY_TYPE_PRIMITIVES_GENERATED_EXT and pipeline stats
interaction is solved by tracking whether pipeline stats query is
running both on CPU (for non secondary cmdbuf case) and on GPU (for
secondary cmdbuf).

Note, prim gen query is not allowed with secondary command buffers, so
only pipeline stats query is tracked on gpu.
See https://gitlab.khronos.org/vulkan/vulkan/-/issues/3142

Counting geometry per each tile is solved by:
- Conditionally executing START/STOP_PRIMITIVE_CTRS to not run in tiling
  pass. Solves the case when prim gen query is inside a renderpass.
- Stop prim counters before executing `draw_cs` and restarting them
  afterwards. Solves prim gen query being outside a renderpass.

Danylo Piliaiev 465e7c303b tu,freedreno: Refactored START/STOP events for pipeline stats

- RST_PIX_CNT -> START_FRAGMENT_CTRS
- RST_VTX_CNT -> STOP_FRAGMENT_CTRS
- TILE_FLUSH  -> START_COMPUTE_CTRS
- STAT_EVENT  -> STOP_COMPUTE_CTRS
I'm not sure about a5xx itself but I'll take a chance of it being
similar to a6xx in this regard.

Knowing this emit_begin_stat_query/emit_end_stat_query can now emit
only events that are needed for the pool's flags.

Also primitive generated query clearly doesn't need fragment and
compute counters.

On a650+ we use the new Z24UINT_S8UINT format to sample the stencil
aspect of D24S8, which returns stencil in the second component and also
uses the second integer component for the border color. However Vulkan
mandates that the first component is used for the stencil border color.
There's no workaround we know of, so we have to fall back to the old
behavior where there is a workaround. If we know the format, we can
fixup the border color ourselves though.

Connor Abbott 39c64a4b53 freedreno/a6xx: Fix border color swizzling
From the API's point of view, border color replacement looks like this:

       --------------------
       | API Border Color |
       --------------------
               |
-----------    |    ----------------      ----------
| API fmt |-------->| User Swizzle |----->| Shader |
-----------         ----------------      ----------

From the HW point of view, it looks like this:

                    -------------------
                    | HW Border Color |
                    -------------------
                             |
----------     -----------   |   ---------------      ----------
| HW fmt |-----| HW swap |------>| Tex Swizzle |----->| Shader |
----------     -----------       ---------------      ----------

When the HW fmt + HW swap isn't enough to represent an API format, we
need to prepend our own swizzle to the the user's swizzle, so the tex
swizzle is a "format swizzle" composed with the user swizzle. However,
we don't want this format swizzle to be applied to border colors, so
there's a workaround in freedreno which is meant to undo the format
swizzle so that the HW border color with the format swizzle applied
equals the API border color, and everything is ok. However, on a6xx at
least it was incorrectly undoing the entire tex swizzle. This broke
border color with a user swizzle, because it was now effectively not
getting applied for the border color. It also made it seem like the user
swizzle is required for the workaround, which would have implications
for VK_EXT_border_color_swizzle with turnip, but it's not.

Danylo Piliaiev 4b5f0d98fd tu: Overhaul LRZ, implement on-GPU dir tracking and LRZ fast-clear
On-GPU LRZ direction tracking allows LRZ to support secondary cmdbufs,
reusing LRZ between renderpasses, and in future to support LRZ when
VK_KHR_dynamic_rendering is used.

With on-gpu tracking we have to be careful keeping LRZ state in sync
with underlying depth image, which means we should invalidate LRZ
when underlying image is changed or the view of image is different
from previous renderpass.

All of this resulted in LRZ logic being thinly spread through the code,
making it hard to understand. So most of it was moved to tu_lrz.c.

For more details on past and new LRZ features see comment at the
top of tu_lrz.c.

Note about blob:
- Blob is much more happy to do LRZ_FLUSH, it flushes at the start
  of the renderpass, after binning, and at the end of the renderpass.
- Blob seem not to care about changes in depth image done via
  vkCmdCopyImage.
