This should make it easier to cross-reference the code and hardware
documentation, as well as clear up any confusion on whether constants
like CMD_3D_WM_STATE mean WM_STATE (pre-gen6) or 3DSTATE_WM (gen6+).
This does not rename any pre-gen6 defines.
|
|
The draw module set new state that didn't require swtnl which caused need_swtnl to
be unset. This caused the call from to svga_update_state(svga, SVGA_STATE_SWTNL_DRAW)
from the vbuf backend to overwrite the vdecls we setup there to be overwritten with
the real buffers vdecls.

For the previous commit.

Previously the 'STDGL invariant(all)' pragma added in GLSL 1.20 was
simply ignored by the compiler. This adds support for setting all
variable invariant.
In GLSL 1.10 and GLSL ES 1.00 the pragma is ignored, per the specs,
but a warning is generated.
Fixes piglit test glsl-invariant-pragma and bugzilla #31925.
NOTE: This is a candidate for the 7.9 and 7.10 branches.

GLSL 1.10 and 1.20 allow any sort of sampler array indexing.
Restrictions were added in GLSL 1.30. Commit f0f2ec4d added support
for the 1.30 restrictions, but it broke some valid 1.10/1.20 shaders.
This changes the error to a warning in GLSL 1.10, GLSL 1.20, and GLSL
ES 1.00.
There are some spurious whitespace changes in this commit. I changed
the layout (and wording) of the error message so that all three cases
would be similar. The 1.10/1.20 and 1.30 text is the same. The only
difference is that one is an error, and the other is a warning. The
GLSL ES 1.00 wording is similar but not quite the same.
Fixes piglit test
spec/glsl-1.10/compiler/constant-expressions/sampler-array-index-02.frag
and bugzilla #32374.

It's no longer needed because the upload buffer remains mapped while the CS
is being filled (openarena, ut2004 and others that this code was for do not
use VBOs by default).
|
|
because the upload buffers are reused for subsequent draw operations.
|
|
|
|
It's called in vbo_exec_invalidate_state too.
|
|
What were these for?
|
|
I also specified the array sizes in the header so that one can use
the Elements macro on it.
|
|
So that a state tracker can unreference them after set_vertex_buffers.
|
|
The overhead of resource_create, transfer_inline_write, and resource_destroy
to upload constant data is very visible with some apps in sysprof, and
as such should be eliminated.
My approach uses a user buffer to pass a pointer to a driver. This gives
the driver the freedom it needs to take the fast path, which may differ
for each driver.
This commit addresses the same issue as Jakob's one that suballocates out
of a big constant buffer, but it also eliminates the copy to the buffer.

- Added a parameter to specify a minimum offset that should be returned.
r300g needs this to better implement user buffer uploads. This weird
requirement comes from the fact that the Radeon DRM doesn't support negative
offsets.
- Added a parameter to notify a driver that the upload flush occured.
A driver may skip buffer validation if there was no flush, resulting
in a better performance.
- Added a new upload function that returns a pointer to the upload buffer
directly, so that the buffer can be filled e.g. by the translate module.
|
|
The map/unmap overhead can be significant even though there is no waiting on busy
buffers. There is simply a huge number of uploads.
This is a performance optimization for Torcs, a car racing game.

Include imports.h directly instead of indirectly through context.h.
version.c does use any symbols that are added by context.h.
|
|
|
|
|
|
Directly include mtypes.h if a file uses a gl_context struct. This
allows future removal of headers that are not strictly necessary but
indirectly include mtypes.h for a file.
|

this fixes doom3 crash.

BaseLevel/MaxLevel are mostly used for two things: clamping texture
access for FBO rendering, and limiting the used mipmap levels when
incrementally loading textures. By restricting our mipmap trees to
just the current BaseLevel/MaxLevel, we caused reallocation thrashing
in the common case, for a theoretical win if someone really did want
just levels 2..4 or whatever of their texture object.
Bug #30366
|
|
We're always making a single-level, 0-baselevel miptree.
|
|
Include mtypes.h for gl_context symbol.
|
|
Include mtypes.h for gl_context symbol.
|
|
This has always been ugly about our texture code -- object base/max
level vs intel object first/last level vs image level vs miptree
first/last level. We now get rid of intelObj->first_level which is
just tObj->BaseLevel, and make intelObj->_MaxLevel clearly based off
of tObj->_MaxLevel instead of duplicating its code (incorrectly, as
image->MaxLog2 only considers width/height and not depth!)
|
|
See section 3.8.10 of the GL 2.1 specification. There's no way to do
anything sane with that, and drivers would get all sorts of angry.
|
|
Fixes lodclamp-between and lodclamp-between-max.
|
|
This avoids 8xx-specific texture relayout for min/max lod changes.
One step closer to avoiding relayout for base/maxlevel changes!
|
|
It's already handled by our non-mipmapped MinFilter, since
TEXTURE_RECTANGLE is always NEAREST or LINEAR.
|
|
It's always BaseLevel (since TEXTURE_RECTANGLE's baselevel can't be
changed from 0), except for 8xx minlod hilarity.
|
|
The SGIS_texture4D extension was thankfully never completed, so we
couldn't implement it if we wanted to.
|
|
|
|
It was quite a mess by trying to do NULL renderbuffers and real
renderbuffers in the same function. This clarifies the common case of
real renderbuffers.

This makes
fbo-generatemipmap-formats GL_EXT_texture_sRGB-s3tc
match
fbo-generatemipmap-formats GL_EXT_texture_compression_s3tc
and swrast in bad DXT1_RGBA alpha=0 handling, but it means we won't
unpack and repack someone's textures into uncompressed SARGB8 format.
|
|
|
|
It's just LUMINANCE, not LUMINANCE_ALPHA. Fixes
fbo-generatemipmap-formats GL_EXT_texture_sRGB-s3tc assertion failure
when it tries to pack the L8 channels into LUMINANCE_ALPHA and wonders
why it's trying to do that.
|
|
We now share the type/format -> MESA_FORMAT_* mappings with software
mesa, and the core supports most of the fallbacks hardware drivers
will want.
|
|
Right now this is just tweaking the current code to look at the table.
Choosing actually supported formats will come later.
|
|
|
|
Use make_temp_float_image instead of _make_temp_chan_image.
The latter converts the texture to 8 bits/component, losing 2 bits.
|
|
This extension doesn't appear to need any driver-specific parts.
|
|
This workaround fixes rendering of kwin thumbnails.

From the r600 ISA:
Each ALU clause can lock up to four sets of constants
into the constant cache. Each set (one cache line) is
16 128-bit constants. These are split into two groups.
Each group can be from a different constant buffer
(out of 16 buffers). Each group of two constants consists
of either [Line] and [Line+1] or [line + loop_ctr]
and [line + loop_ctr +1].
For supporting more than 64 constants, we need to
break the code into multiple ALU clauses based
on what sets of constants are needed in that clause.
Note: This is a candidate for the 7.10 branch.
