10 years agoi965/vec4: Handle ir_triop_lrp on Gen4-5 as well.

i965/vec4: Handle ir_triop_lrp on Gen4-5 as well.

When the vec4 backend encountered an ir_triop_lrp, it always emitted an
actual LRP instruction, which only exists on Gen6+.  Gen4-5 used
lower_instructions() to decompose ir_triop_lrp at the IR level.

Since commit 8d37e9915a3b21 ("glsl: Optimize open-coded lrp into lrp."),
we've had an bug where lower_instructions translates ir_triop_lrp into
arithmetic, but opt_algebraic reassembles it back into a lrp.

To avoid this ordering concern, just handle ir_triop_lrp in the backend.
The FS backend already does this, so we may as well do likewise.

v2: Add a comment reminding us that we could emit better assembly if we
    implemented the infrastructure necessary to support using MAC.

mesa: allow buffers to be mapped multiple times

internally, e.g. in the software primitive restart fallback, for PBOs,
vbo_get_minmax_index, etc. This has always been a problem, but it will
be a bigger problem with persistent buffer mappings, which will prevent
all Mesa functions from mapping buffers for internal purposes.

This adds a driver interface to core Mesa which supports multiple buffer
mappings and allows 2 mappings: one for the GL user and one for Mesa.

Note that Gallium supports an unlimited number of buffer and texture
mappings, so it's not really an issue for Gallium.

i965: Don't try to use the hardware blitter for multisampled miptrees.

The blitter is completely ignorant of MSAA buffer layouts, so any
attempt to use BLT paths with MSAA buffers is likely to break
spectacularly.

In most cases, BLORP handles MSAA blits, so we never hit this bug.
Until recently, it also wasn't worth fixing, since Meta couldn't handle
MSAA either, so there was nothing to fall back to.  But now there is.

+143 piglit tests on Broadwell (which doesn't have BLORP support).
Surprisingly, three also start failing.  Since non-IMS MSAA buffers
store samples in successive array slices, using the blitter ought to
access sample 0 and ignore the rest, which is apparently good enough for
a few not-very-picky Piglit tests.  Presumably the meta replacement code

freedreno/a3xx/compiler: half-precision output

Using generic shaders caused a measurable fps drop, which was isolated to
use of full precision (vs half precision) output.  This is an attempt to
regain that lost performance by using half precision solid/blit shaders
(when the output format is not float32).

Note: for the built-in shaders, I would not expect them to be register
starved.  And in fact it is the solid frag shader that seems to have the
biggest impact.  So I suspect you get double the pixel pipe units (or
half the cycles) when the output is half precision.  So there may be
some gain to using half precision output for application shaders as
well, even though the rest of register usage is still full precision.
But for half precision to work for more complex shaders, we need to deal
with some constraints, like cat2 needing same precision for it's two src
registers.  So for now it is not enabled by default except for the
built-in shaders.

10 years agoilo: fix and enable fast depth clear
Chia-I Wu [Thu, 16 Jan 2014 07:29:03 +0000 (15:29 +0800)]
ilo: fix and enable fast depth clear

Use tex->bo_format instead of zs->format in ilo_blitter_rectlist_clear_zs()
because the latter may be combined depth/stencil format.  hiz_can_clear_zs()
is no-op for GEN7+, but move the GEN check so that the assertions are tested.

Finally, call the fast depth clear function from ilo_clear().

ilo: add slice clear value

It is needed for 3DSTATE_CLEAR_PARAMS, and can also be used to track what
value the slice has been cleared to.

Improve comments for the flags, and explicitly separate their uses in slice
flags and resolve flags.

10 years agoilo: fix for stencil only rectlist ops

ilo: fix for stencil only rectlist ops

3DSTATE_STENCIL_BUFFER inherits some states from 3DSTATE_DEPTH_BUFFER.  We
need to emit both even the surface is stencil only.
