* mesa: Fixed a texture memory leakRobert Ellison2009-05-081-0/+3
| | | | | | | | | | | | The current texture for any particular texture unit is given an additional reference in update_texture_state(); but if the context is closed before that texture can be released (which is quite frequent in normal use, unless a program unbinds and deletes the texture and renders without it to force a call to update_texture_state(), the memory is lost. This affects general Mesa; but the i965 is particularly affected because it allocates a considerable amount of additional memory for each allocated texture.

| | | | | | | | | | | two) The semantics are a little different for shaders vs. fixed-function when trying to use an incomplete texture. The fallback texture returning (0,0,0,1) should only be used with shaders. For fixed function, the texture unit is truly disabled/ignored. Fixes glean fbo test regression.

| | | | | | This reverts commit a0edbfb28fb2e670c657d52190a7e8b1ccf4f46e. This patch didn't completely fix the problem. The next patch will.

* mesa: create/use a fallback texture when bound texture is incompleteBrian Paul2009-05-011-2/+7
| | | | | | | | | | | | | | When a GLSL sampler reads from an incomplete texture it should return (0,0,0,1). Instead of jumping through hoops in all the drivers to make this happen, just create/install a fallback texture with those texel values. Fixes piglit/fp-incomplete-tex on i965 and more importantly, fixes some GPU lockups when trying to sample from missing surfaces. If a binding table entry is NULL, it seems that sampling sometimes works, but not always (lockup). Todo: create a fallback texture for each type of texture target?

| | | | | | | | add new entrypoints, new texture format, etc translate in texenvprogram.c for drivers using the mesa-generated tex env fragment program also handled in swrast, but not tested (cannot work due to negative texel results not handled correctly)
* mesa: remove gl_texture_object::_Function field and associated codeBrian Paul2009-03-111-32/+0
| | | | It was only used in one place in swrast.
* mesa: move call to update_texture_compare_function()Brian Paul2009-03-021-3/+1
| | | | Another conditional can be avoided.
* mesa: fix texture enable regressionBrian Paul2009-03-021-2/+3
| | | | | | | Need to clear the _ReallyEnabled field before possibly continuing the loop. Also, set _Current pointer to NULL if the unit is no longer enabled. Fixes piglit lodbias regression
* mesa: use _mesa_reference_texobj() when setting texUnit->Current pointerBrian Paul2009-03-021-2/+1
| | | | Fixes piglit copytexsubimage regression.
* mesa: fixed computation of _EnabledCoordUnitsBrian Paul2009-03-021-8/+18
| | | | | This field should not include vertex textures. It indicates the coord inputs for fragment / fixed-function processing.
* mesa: move texture_override() code into calling loopBrian Paul2009-03-021-30/+19
| | | | We can avoid a few iterations this way.

|
* mesa: use enums for TEXTURE_x_INDEX valuesBrian Paul2009-02-211-17/+3
| | | | | Plus, put them in the order of highest to lowest priority to simplify the texture_override() loop.
* mesa: use an array for current texture objectsBrian Paul2009-02-211-66/+37
| | | | Use loops to consolidate lots of texture object code.
* mesa: use an array for default texture objectsBrian Paul2009-02-211-15/+23
| | | | | Replace Default1D/2D/3D/Cube/etc with DefaultTex[TEXTURE_x_INDEX]. The same should be done with the Current1D/2D/3D/etc pointers...
* mesa: re-org texgen stateBrian Paul2009-02-211-39/+26
| | | | New gl_texgen struct allows quite a bit of code reduction.

* mesa: fix logic error in computing enableBits in update_texture_state()Brian Paul2009-02-071-10/+12
| | | | | | | If we had a vertex shader but no fragment shader (i.e. fixed function) we didn't get the right enabled texture targets. Fixes blank/white texture problem.
* mesa: remove GL_SGIX_shadow, GL_SGIX_shadow_ambient and GL_SGIX_depth_textureBrian Paul2009-01-281-10/+0
| | | | Everyone should be using the newer/better ARB versions of these extensions.
* mesa: update state setup/validation for GL_NV_texture_env_combine4Brian Paul2009-01-231-7/+18
|
* mesa: add some debug assertions to detect null current texture object pointersBrian Paul2009-01-211-0/+8
| | | | See bug #17895. These assertions could be removed when this is resolved.
* mesa: increase max texture image units and GLSL samplers to 16Brian Paul2008-12-311-6/+5
| | | | | | | | | | | | | | | | The max texture coord units is still 8. All the fixed-function paths are still limited to 8 too. But GLSL shaders can use more samplers now. Note that some texcoord-related data structures are declared to be 16 elements in size rather than 8. This just simplifies the code in a few places; the extra elements aren't accessible to the user. These changes haven't been extensively tested yet, but sanity checking has been done. It should be possible to increase the max image units/samplers to 32 without doing anything special. Beyond that we'll need longer bitfields in a few places.

* Flush vertices when updating texObj->GenerateMipmap state.Eric Anholt2008-08-211-0/+1
| | | | Caught by texturing/gen-teximage test in piglit.
* Enable TexGen based on InputsRead when a fragment program is activeNicolai Haehnle2008-07-041-10/+18
| | | | | | | The old behaviour depended on which texture images the fragment program reads from, which seems to contradict the shader specifications. Note: Piglit's general/texgen test checks for this problem.
* Add support for GL_REPLACE_EXT texture env mode.Brian Paul2008-04-301-1/+6
| | | | | | GL_REPLACE_EXT comes from the ancient GL_EXT_texture extension. Found an old demo that actually uses it. The values of the GL_REPLACE and GL_REPLACE_EXT tokens is different, unfortunately.
