The whole structure is 836 bytes, but if only the first one or two
samplers are used (as is common), the part that matters is only 56 or
108 bytes. By using just that subset as the key (since the key size
is also part of the key), we improve firefox-talos-gfx performance by
1%.
|
|
|
|
|
|
Since it's a BO pointer, it already lives outside the key in
brw->wm.sdc_bo[] which is used for sampler state lookup and setup.

This saves 6.6KB on the 965 driver, and appears to speed
firefox-talos-gfx up by 1-2%. Unlike many other asserts in the
driver, when we make a mistake that would trigger one of these it
generally shows up all the time for developers, so turning it off for
release seems fine.

This manages to cut down another 3800 bytes.

Cuts another 1800 bytes from the driver.

Shaves 800 bytes off the driver.

Shaves 60k off the driver from removing the broken spans code. This
means we now require 2.6.29, which seems fair given that it's a year
old and we've removed support for non-KMS already in the last release
of 2D.
|
|
Shaves 5.5k off of the driver.

This now passes piglit testcases, and shows performance improvements
on openarena. Blit-heavy apps may see degradation, but the
expectation is that the common case of 3D rendering will see
significant wins.
This regresses gen-teximage on my 855, and no piglit tests on my 945.

Corresponds to b87406e55f029d29594ae76a4b39a4fe1007fe4f.

The break in the __DRI_ATTRIB_RENDER_TYPE case was accidentally
removed in commit 5cf2c5851bcd29c2d53bb04ab692b4b156f5a74d. This puts
it back.

Only tested this on my rv530 with R300_NO_TCL=1, but it works there
at least. It would be nice to fix the tex_offset by chaning the vertex
program on tcl to read from offset 6 but this isn't really necessary.

at least on the r500 we get a lockup unless I do this, the compiler
seems to fail to compile and we just get a null fp.

Check if the native blit formats are supported, if not,
attempt to use an alternate format.
Skip 3, >4 bpp as per comments from mcencora on irc.

Now that color-index support is removed from t_dd_tritmp.h and
t_dd_unfilled.h, drivers no longer need define HAVE_RGBA.

These are used to inform the driver of the clear value for color-index
buffers and to control write-masking of bits in color-index buffers.
No driver use or need (not even Nouveau) these interfaces.

It appears that color-index rendering wasn't actually supported
anyway. swrastFillInModes did not previously create an color-index
configs, so it doesn't seem like there would be any way to get a
color-index visual.

This should fix rendering into mipmaps of tiled textures.
|
|
This improves tiled texture performance of OA on my 945 from 25.3fps
to 29.0fps, whereas untiled is 28.2fps, by avoiding stalls for fence
register changes.
|
|
This moves the logic for how to align pitches, heights, and sizes of
objects to one central location. Fixes rendering with texture tiling
on i915. Note that current libdrm is required for the change for
I915_TILING_NONE pitch alignment.
|
|
The weirdness that led to the bumping of pitch for those 512/1024
pixels is that in taking a 2x2 subspan or bilinear filtering we'd end
up hitting the same channel in 2 different pages, leading to lower
performance. With tiling, that doesn't occur, so we don't need to
waste the memory.

there is no need for these to be persistent since we flush the CS
at the end of the blit, and we don't reuse these buffers at all.
on my r600 the Wine DX9 test suite doesn't crash at least anymore.

DMA buffers are often remapped many times for singel cs. To reduce number of
mapping calls ending to kernel dma buffers are mapped when allocated and unmapped
when full or in cs flush. This makes indifual mapping calls in other parts of
code simple increment/decrement reference count which is faster than entering
kernel.
This improves Anholt's openarena benchmark from 36 fps to 44 fps.
