* mesa: fix _mesa_get_fallback_texture() to handle all texture targetsBrian Paul2012-02-151-2/+8
| | | | | | | | | | | | Previously, this function only handled 2D textures. The fallback texture is used when we try to sample from an incomplete texture object. GLSL says sampling an incomplete texture should return (0,0,0,1). v2: use a 1-texel texture image, per José. Reviewed-by: Jose Fonseca <[email protected]>
* mesa: fix proxy texture target initializationBrian Paul2012-02-101-7/+12
| | | | | | | | | | | The mapping from TEXTURE_x_INDEX to GL_TEXTURE_x was broken in alloc_proxy_textures() because the elements in the targets[] array were in the wrong order. This didn't actually cause any failures since we never really use the proxy texture's Target field. But let's get it right. NOTE: This is a candidate for the 8.0 branch.

* mesa: add support for GL_OES_EGL_image_externalChia-I Wu2011-11-031-1/+2
| | | | | | | | | This is an OpenGL ES specific extension. External textures are textures that may be sampled from, but not be updated (no glTexSubImage* and etc.). The image data are taken from an EGLImage. Reviewed-by: Brian Paul <[email protected]> Acked-by: Jakob Bornecrantz <[email protected]>

| | | | | | | | | | | | | | EXT_shared_texture_palette This was also discussed at XDS 2010. However, actually making the change was delayed because several drivers still exposed these extensions to significant benefit (e.g., tdfx). Now that those drivers have been removed, this code can be removed as well. v2: A lot of bits that were missed in the previous patch have been removed.

* mesa: move sampler state into new gl_sampler_object typeBrian Paul2011-04-101-1/+7
| | | | | | gl_texture_object contains an instance of this type for the regular texture object sampling state. glGenSamplers() generates new instances of gl_sampler_object which can override that state with glBindSampler().

* mesa: increase number of texture units to MAX_COMBINED_TEXTURE_IMAGE_UNITSBrian Paul2010-02-031-10/+19
| | | | | | | | | | | | | | | | | | | We were misinterpretting GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS previously. It's the number of texture units for which we need to keep state; not just the total number of texture units addressable by the vertex shader plus fragment shader. Since sw Mesa independently supports 16 texture units in vertex shaders and 16 texture units in fragment shaders, the max combined units is 32. Note that the docs for glActiveTexture() indicate the max legal unit is MAX(GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS, MAX_TEXTURE_COORDS) - 1. A new piglit test (texunits.c) tests the various texture unit limits. I'm pretty sure I've got this all right now, but additional reviews are welcome...

* 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.

* 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?
