softpipe: try to beat new dx10-style sample opcodes into shape

There were several bugs how this was handled, most opcodes wouldn't even
have fetched the right arguments.
Also, the tex "target" is coming from the sampler view, hence it cannot
have information about shadow comparisons - fortunately this is not only
sampler state but also needs to have matching instruction, so just use this
instead to identify shadow comparisons.
Still untested (compiles...).
Note that sample_i and sviewinfo are still busted (just assert).
(The problem is that the interface for doing the opengl-equivalent functions
txf and txq is tied to the specific the sampler itself but these opcodes
have no sampler associated with them. Oops...)
Also, even the other sample instructions will not work correctly since
they always operate on samplers which include the texture state. Fixing
this wouldn't be that difficult but most likely make softpipe quite a bit
slower when using the OpenGL tex opcodes (as the samplers have pre-baked
function calls in the sampler state depending on texture state and that stuff
would need to be evaluated at runtime), so leave it for now.

11 years agointel/pre-gen6: Disable EXT_framebuffer_multisample.
Paul Berry [Mon, 28 Jan 2013 19:13:07 +0000 (11:13 -0800)]
intel/pre-gen6: Disable EXT_framebuffer_multisample.

Previously, the i965 driver enabled EXT_framebuffer_multisample even
on pre-gen6 chipsets.  However, since we don't support multisampling
on these chips, we set GL_MAX_SAMPLES=1 (the minimum allowed by
EXT_framebuffer_multisample), and if the client ever requested a
multisample buffer, we quietly supplied them with a single-sampled
buffer instead.

After some discussion on the mailing list (see thread
"ext_framebuffer_multisample: check for num_samples<=1"), it's clear
that this was the wrong approach.  The correct approach is to only
expose EXT_framebuffer_multisample when we truly support
multisampling; that frees us to set a sensible value of
GL_MAX_SAMPLES=0 on other chipsets, so that we never have to deal with
a client requesting a multisample buffer when multisampling isn't
supported.

This change causes the following piglit tests to be skipped on
chipsets prior to Gen6:

- "ARB_framebuffer_sRGB/blit {renderbuffer,texture}
  {linear,linear_to_srgb,srgb,srgb_to_linear}
  {downsample,msaa,upsample} {disabled,enabled}"
- EXT_framebuffer_multisample/blit-mismatched-formats
- EXT_framebuffer_multisample/blit-mismatched-sizes
- EXT_framebuffer_multisample/dlist
- EXT_framebuffer_multisample/interpolation 0 *
- EXT_framebuffer_multisample/minmax
- EXT_framebuffer_multisample/negative-copypixels
- EXT_framebuffer_multisample/negative-copyteximage
- EXT_framebuffer_multisample/negative-max-samples
- EXT_framebuffer_multisample/negative-mismatched-samples
- EXT_framebuffer_multisample/negative-readpixels
- EXT_framebuffer_multisample/renderbuffer-samples
- EXT_framebuffer_multisample/renderbufferstorage-samples
- EXT_framebuffer_multisample/samples

This is expected, since the above tests exercise MSAA functionality,
and shouldn't be run on systems prior to Gen6.

mesa: Don't check (offset + size <= bufObj->Size) in BindBufferRange.

In the documentation for BindBufferRange, OpenGL specs from 3.0
through 4.1 contain this language:

    "The error INVALID_VALUE is generated if size is less than or
    equal to zero or if offset + size is greater than the value of
    BUFFER_SIZE."

This text was dropped from OpenGL 4.2, and it does not appear in the
GLES 3.0 spec.

Presumably the reason for the change is because come clients change
the size of the buffer after calling BindBufferRange.  We don't want
to generate an error at the time of the BindBufferRange call just
because the old size of the buffer was too small, when the buffer is
about to be resized.

Since this is a deliberate relaxation of error conditions in order to
allow clients to work, it seems sensible to apply it to all versions
of GL, not just GL 4.2 and above.

(Note that there is no danger of this change allowing a client to
access data beyond the end of a buffer.  We already have code to
ensure that that doesn't happen in the case where the client shrinks
the buffer after calling BindBufferRange).

i965/blorp: Support blits between ARGB and XRGB formats.

Now that we have support for overriding alpha to 1.0, we can handle
blitting between these formats in either direction.

For now, we only support two XRGB formats: MESA_FORMAT_XRGB8888 and
MESA_FORMAT_RGBX8888_REV.  Most places only appear to worry about the
former, so ignore the latter for now.  We can always add it later.

i965/blorp: Support overriding destination alpha to 1.0.

Currently, Blorp requires the source and destination formats to be
equal.  However, we'd really like to be able to blit between XRGB and
ARGB formats; our BLT engine paths have supported this for a long time.

For ARGB -> XRGB, nothing needs to occur: the missing alpha is already
interpreted as 1.0.  For XRGB -> ARGB, we need to smash the alpha
channel to 1.0 when writing the destination colors.  This is fairly
straightforward with blending.

For now, this code is never used, as the source and destination formats
still must be equal.  The next patch will relax that restriction.

11 years agoi965: Implement CopyTexSubImage2D via BLORP (and use it by default).
Kenneth Graunke [Wed, 16 Jan 2013 06:17:23 +0000 (22:17 -0800)]
i965: Implement CopyTexSubImage2D via BLORP (and use it by default).

The BLT engine has many limitations.  Currently, it can only blit
X-tiled buffers (since we don't have a kernel API to whack the BLT
tiling mode register), which means all depth/stencil operations get
punted to meta code, which can be very CPU-intensive.

Even if we used the BLT engine, it can't blit between buffers with
different tiling modes, such as an X-tiled non-MSAA ARGB8888 texture
and a Y-tiled CMS ARGB8888 renderbuffer.  This is a fundamental
limitation, and the only way around that is to use BLORP.

Previously, BLORP only handled BlitFramebuffer.  This patch adds an
additional frontend for doing CopyTexSubImage.  It also makes it the
default.  This is partly to increase testing and avoid hiding bugs,
and partly because the BLORP path can already handle more cases.  With
trivial extensions, it should be able to handle everything the BLT can.

This helps PlaneShift massively, which tries to CopyTexSubImage2D
between depth buffers whenever a player casts a spell.  Since these
are Y-tiled, we hit meta and software ReadPixels paths, eating 99% CPU
while delivering ~1 FPS.  This is particularly bad in an MMO setting
because people cast spells all the time.

It also helps Xonotic in 4X MSAA mode.  At default power management
settings, I measured a 6.35138% +/- 0.672548% performance boost (n=5).
(This data is from v1 of the patch.)

No Piglit regressions on Ivybridge (v3) or Sandybridge (v2).

v2: Create a fake intel_renderbuffer to wrap the destination texture
    image and then reuse do_blorp_blit rather than reimplementing most
    of it.  Remove unnecessary clipping code and conditional rendering
    check.

v3: Reuse formats_match() to centralize checks; delete temporary
    renderbuffers.  Reorganize the code.

v4: Actually copy stencil when dealing with separate stencil buffers but
    packed depth/stencil formats.  Tested by a new Piglit test.

gallium: add SQRT shader opcode

The glsl-to-tgsi translater will emit SQRT to implement GLSL's sqrt()
and distance() functions if the PIPE_SHADER_CAP_TGSI_SQRT_SUPPORTED
query says it's supported by the driver.

Otherwise, sqrt(x) is implemented with x*rsq(x).  The problem with
this is sqrt(0) must be handled specially because rsq(0) might be
Inf/NaN/undefined (and then 0*rsq(0) is Inf/Nan/undefined).  In the
glsl-to-tgsi code we use an extra CMP to check if x is zero and then
replace the result of x*rsq(x) with zero.

In the end, this makes sqrt() generate much more reasonable code for
drivers that can do square roots.

Note that many of piglit's generated shader tests use the GLSL
distance() function.

i965: Fix the SF Vertex URB Read Length calculation for Sandybridge.

(This commit message was primarily written by Paul Berry, who explained
 what's going on far better than I would have.)

Previous to this patch, we thought that the only restrictions on
3DSTATE_SF's URB read length were (a) it needs to be large enough to
read all the VUE data that the SF needs, and (b) it can't be so large
that it tries to read VUE data that doesn't exist.  Since the VUE map
already tells us how much VUE data exists, we didn't bother worrying
about restriction (a); we just did the easy thing and programmed the
read length to satisfy restriction (b).

However, we didn't notice this erratum in the hardware docs: "[errata]
Corruption/Hang possible if length programmed larger than recommended".
Judging by the context surrounding this erratum, it's pretty clear that
it means "URB read length must be exactly the size necessary to read all
the VUE data that the SF needs, and no larger".  Which means that we
can't program the read length based on restriction (b)--we have to
program it based on restriction (a).

The URB read size needs to precisely match the amount of data that the
SF consumes; it doesn't work to simply base it on the size of the VUE.

Thankfully, the PRM contains the precise formula the hardware expects.

Fixes random UI corruption in Steam's "Big Picture Mode", random terrain
corruption in PlaneShift, and Piglit's fbo-5-varyings test.
