* i965: added null const_buffer pointer check in update_constant_buffer()Brian Paul2009-04-101-1/+1
|
* intel: added screen->dri2.loader null pointer check in intel_flush()Brian Paul2009-04-101-1/+2
| | | | Fixes segfaults when rendering to front buffer.
* gallium: remove pipe_texture::compressed fieldBrian Paul2009-04-101-1/+0
| | | | | The format field encodes compressed vs. uncompressed already. We can easily check if a texture is compressed with pf_is_compressed(texture->format).
* swrast: remove some unneeded CHAN_TYPE!=GL_FLOAT codeBrian Paul2009-04-091-7/+0
|
* i965: re-org of some of the new constant buffer codeBrian Paul2009-04-094-48/+81
| | | | Plus, begin the new code for vertex shader const buffers.
* i965: new SURF_INDEX_ macrosBrian Paul2009-04-095-40/+49
| | | | | Used to map drawables, textures and constant buffers to surface binding table indexes.
* intel / DRI2: Accept fake front-buffer from loaderIan Romanick2009-04-091-0/+5
| | | | | | | | | Handle the loader returning a fake front-buffer. Since the driver never specifically requests a fake front-buffer, the driver assumes that it will never receive both a fake and a real front-buffer.

* intel / DRI2: Track and flush front-buffer renderingIan Romanick2009-04-093-0/+46
| | | | | | | | | | | Track two flags: whether or not front-buffer rendering is currently enabled and whether or not front-buffer rendering has been enabled since the last glFlush. If the second flag is set, the front-buffer is flushed via a loader call back. If the first flag is cleared, the second flag is cleared at this time.

* st: remove another unneeded 'is compressed' comparisonBrian Paul2009-04-091-2/+3

* st: remove unneeded "is compressed" checkBrian Paul2009-04-091-2/+1
| | | | The format indicates compressed vs. uncompressed.

* st: remove comp_byte parameter to st_texture_create()Brian Paul2009-04-096-20/+9
| | | | We can determine if the texture is compressed by checking the format.

* mesa: fix potential recursive locking deadlock in _mesa_HashWalk()Brian Paul2009-04-091-4/+14
| | | | If the walk callback called _mesa_HashRemove() we'd deadlock.
* i965: free shader's constant buffer in brwDeleteProgram()Brian Paul2009-04-091-0/+6
| | | | Fixes mem leak observed with texcombine test.
* i965: set BRW_MASK_DISABLE flag in "send" instruction in brw_dp_READ_4()Brian Paul2009-04-081-1/+2
| | | | | | This fixes the random results that were seen when fetching a constant inside an IF/ELSE clause. Disabling the execution mask ensures that all the components of the register are written.
* i965: clean-ups, debug code in brw_wm_glsl.cBrian Paul2009-04-081-34/+15
|
* i965: init current_const[i].index = -1Brian Paul2009-04-081-3/+4
|
* i965: move the fetch_constants() call before setting conditional mod stateBrian Paul2009-04-081-4/+4
| | | | | | | | Before, the instruction's CondUpdate field was mistakenly effecting the constant-fetch operation. Fixes progs/glsl/bump.c demo. But there are some other issues related to condition flags and IF/ELSE that need investigation...

* Mesa: allow suppression of debug messages in a debug buildRobert Ellison2009-04-081-10/+32
| | | | | | | | | | | | | | | | | | | | | For testing, it's very useful to be able to test on a debug build, while suppressing the debug messages (messages that are by default suppressed in a release build), in order to see the same behavior that users of release builds will see. For example, the "piglit" test suite will flag an error on programs that produce unexpected output, which means that a debug build will always fail due to the extra debug messages. This change introduces a new value to the MESA_DEBUG environment variable. In a debug build, explicitly setting MESA_DEBUG to "0" will suppress all debug messages (both from _mesa_debug() and from _mesa_warning()). (The former behavior was that debug messages were never suppressed in debug builds.) Behavior of non-debug builds has not changed. In such a build, _mesa_debug() messages are always suppressed, and _mesa_warning() messages will be suppressed unless MESA_DEBUG is set *to any value*.

* swrast: fix point rendering function selectionBrian Paul2009-04-071-1/+4
| | | | | Need to clamp default point size to min/max range before checking if it's one. Fixes glean pointAtten test.
* mesa: fix incorrect component ordering for sRGB8 texture fetch/storeBrian Paul2009-04-071-5/+6
| | | | | | This format is layered on MESA_FORMAT_RGB888 so the component order is actually BGR. Fixes glean pixelFormat failures.
* glsl: enable the new linear scan register allocator codeBrian Paul2009-04-071-3/+3
| | | | | Seems to b working well enough to enable all the time. Optimizations can be disabled with "export MESA_GLSL=nopt" if needed.

* st: as with swrast, interpret texture border color according to texture formatBrian Paul2009-04-061-4/+37
| | | | | Depending on the hardware driver this might not be needed, but it will cause no harm.

* swrast: fix texture border color interpretationBrian Paul2009-04-061-30/+68
| | | | | | | The texture border color must be interpreted according to the texture's base format. For example, for a GL_ALPHA texture, sampling the border color should return (0,0,0,borderAlpha). This wasn't an issue here until I removed the legacy texenv code (we always use the combiner path now).

| | | | Fixes conform spcorner.c & spclear.c failure.
* intel: Avoid dri2 GetBuffers round-trips for internal Viewport calls.Eric Anholt2009-04-063-3/+10
| | | | | | This gets us the savings for driver-internal viewport calls that dd1c68f15123a889a3ce9d2afe724e272d163e32 was attempting, without relying on Xlib internals or clients handling X events.
* i965: Use GTT maps when available to upload vertex arrays and system VBOs.Eric Anholt2009-04-063-18/+55
| | | | | | | This speeds up OA on my GM45 by 21% (more than the original CPU cost of the upload path). We might still be able to squeeze a few more percent out by avoiding repeatedly mapping/unmapping buffers as we upload elements into them.

* radeon: Expose a 32 bit RGBA fbconfig even when the screen depth is 16.Michel Dänzer2009-04-061-15/+20
| | | | | | | Otherwise current xserver / libGL no longer expose a 32 bit RGBA GLX visual, and compiz fails. Fixes http://bugs.freedesktop.org/show_bug.cgi?id=20479 .
