73da0dcddc gallium: eliminate frontend refcounting from samplerviews
Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
macOS-CI / macOS-CI (xlib) (push) Waiting to run
A significant CPU performance bottleneck in mesa GL is refcounting atomics:
even with the current pinning attempts, eliminating them can yield huge
performance gains (easily verified by running drawoverhead with return false at the top of pipe_reference_described()).

This is a proof of concept for removing refcounts from gallium objects,
namely sampler views and resources. Sampler views were smaller in scope,
so I started there. This MR alone is not expected to noticeably affect
performance, though if applied to all drivers/frontends,
it would enable a bunch of code deletion for crazy samplerview
refcounting hacks currently used to try circumventing the existing overhead.

47c1f389ed gallium: remove take_ownership from set_vertex_buffers, assume it's true
This removes the take_ownership parameter and defines the behavior as if
take_ownership was always true, which is the fast path. This way, we don't
have to have 2 codepaths in set_vertex_buffers of every driver.

The old behavior is optionally available through util_set_vertex_buffers.

It also documents a new constraint that count in set_vertex_buffers must be
equal to the number of vertex buffers referenced by vertex elements or 0.

This patch removes start_slot from set_vertex_buffers() as suggested in
https://gitlab.freedesktop.org/mesa/mesa/-/issues/8142

compilation testing:
all gallium drivers, nine frontend compilation has been tested.
d3d10umd compilation has not been tested

driver, frontend testing:
only llvmpipe and radeonsi driver was tested running game

only the nine frontend changes are complex. All other changes are easy.
nine front end was using start slot and also using multi context.

nine frontend code changes:
In update_vertex_elements() and update_vertex_buffers(), the vertex
buffers or streams are ordered removing the holes. In update_vertex_elements()
the vertex_buffer_index is updated for pipe driver to match the ordered list.

v2: remove start_slot usage code from Marek (Marek Olšák)
v3: nine stream number holes mask code from Axel (Axel Davy)

606e42027e gallium: add hook on getting canonical format
On swizzled copies canonical formats are used to reduce the formats to a

Nevertheless, it is possible that some of the canonical formats defined
in Gallium are actually not supported by the drivers themselves.

This provides a driver-defined hook that can be used to provide an
alternative canonical format in case the canonical one defined by
Gallium is not supported by the driver.

27dcb46629 gallium: add take_ownership param into set_vertex_buffers to eliminate atomics
There are a few places (mainly u_threaded_context) that do:
   set_vertex_buffers(...);
   for (i = 0; i < count; i++)
      pipe_resource_reference(&buffers[i].resource.buffer, NULL);

set_vertex_buffers increments the reference counts while the loop
decrements them.

This commit eliminates those reference count changes by adding a parameter
into set_vertex_buffers that tells the callee to accept all buffers
without incrementing the reference counts.

AMD Zen benefits from this because it has slow atomics if they come from
different CCXs.

a51d4b10f1 gallium: add take_ownership param into set_constant_buffer to eliminate atomics
We often do this:
    pipe->set_constant_buffer(pipe, shader, slot, &cb);
    pipe_resource_reference(&cb->buffer, NULL);

That results in atomic increment in set_constant_buffer followed by
atomic decrement after set_constant_buffer. This new interface
eliminates those atomics.

For the case above, this should be used instead:
    pipe->set_constant_buffer(pipe, shader, slot, true, &cb);
    cb->buffer = NULL; // if cb is not a local variable, else do nothing

AMD Zen benefits from this. The perf improvement is ~3% for Viewperf13/Catia.

86328fc7b7 gallium: add a cond rendering hook for vulkan.
The vulkan cond rendering hook is quite different than the
traditional gallium one so add a new interface for it.

This just conditionalises rendering on the memory location.

05f35a50e3 gallium: remove and emulate PIPE_CAP_MULTI_DRAW
To remove PIPE_CAP checking in the common code.

It's better if drivers lower multi draws even if the hardware doesn't
support it beause the multi draw loop can be moved deeper into the driver
to remove more overhead.

1cd455b17b gallium: extend draw_vbo to support multi draws
Essentially rename multi_draw to draw_vbo and remove start and count

anywhere.
