* svga: Add GL4.1(compatibility profile) support in svga driverNeha Bhende2020-06-051-28/+77
| | | | | | | | | This patch is a squash commit of a very long in-house patch series. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Charmaine Lee <[email protected]> Signed-off-by: Neha Bhende <[email protected]> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/5317>
* util: Move gallium's PIPE_FORMAT utils to /util/format/Eric Anholt2019-11-141-1/+1
| | | | | | | | | | | | | | | To make PIPE_FORMATs usable from non-gallium parts of Mesa, I want to move their helpers out of gallium. Since u_format used util_copy_rect(), I moved that in there, too. I've put it in a separate directory in util/ because it's a big chunk of related code, and it's not clear to me whether we might want it as a separate library from libmesa_util at some point.

* svga: add svga shader type in the shader variantCharmaine Lee2019-03-081-15/+16
| | | | | | | | With this patch, the svga shader type will be saved in the shader variant, and there is no need to pass in the shader type to the define/destroy variant functions. Reviewed-by: Brian Paul <[email protected]>
* svga: change svga_destroy_shader_variant() to return voidBrian Paul2018-10-091-3/+2
| | | | | | | | | | | | | svga_destroy_shader_variant() itself flushes and retries the command if there's a failure. So no need for the callers to do it. Other callers of the function were already ignoring the return value. This also fixes a corner-case double-free reported by Coverity (and reported by Dave Airlie). Tested with various OpenGL apps.

* svga: add format conversion for legacy formatsCharmaine Lee2018-09-101-14/+76
| | | | | | | | | | | This patch extends the format_conversion table to support different view formats on texture buffer. For legacy image formats such as INTENSITY, LUMINANCE, LUMINANCE_ALPHA, special swizzle masks will be used on the red or RG channels.

| | | | | | | | | | | | | Sometimes, converting unnormalized coordinates to normalized coordinates requires an epsilon value to produce the right texels with nearest filtering. Adding 0.0001 to the coordinates when the min/mag filter is nearest fixes the issue.

* svga: don't call svga_texture_device_format_has_alpha() for PIPE_BUFFERBrian Paul2017-07-031-1/+2
| | | | | | | | | | | svga_texture_device_format_has_alpha() is only intended to work for texture resources, not buffer resources. This fixes a failed assertion in the svga_texture() cast function when running texture buffer tests. Also, add an assertion in svga_texture_device_format_has_alpha() to catch the issue sooner.

* svga: fix texture buffer object regressionBrian Paul2017-07-031-9/+11
| | | | | | | | | | | | With change 8aba778fa2cd98a0b5a7429d3c5057778a0c808c we stopped binding sampler objects for texture buffers. That broke our texture sample / sampler view setup code. Now, we loop over the max(num samplers, num sampler views) and handle the sampler and view information separately. For texture buffers, the sampler will be NULL but the sampler view non-null.

| | | | | | | | | | If the XRGB view is sampling from an ARGB svga format, change PIPE_SWIZZLE_W to PIPE_SWIZZLE_1 for all channels.

* svga: use shader sampler view declarationsBrian Paul2016-03-211-9/+7
| | | | | | | | | | | | | | Previously, we looked at the bound textures (via the pipe_sampler_views) to determine texture dimensions (1D/2D/3D/etc) and datatype (float vs. int). But this could fail in out of memory conditions. If we failed to allocate a texture and didn't create a pipe_sampler_view, we'd default to using 0 (PIPE_BUFFER) as the texture type. This led to device errors because of inconsistent shader code. This change relies on all TGSI shaders having an SVIEW declaration for each SAMP declaration. The previous patch series does that.
