| | | | | | | | | | | | | | | | | belong in driver code The implementation of texture <-> pixel-buffer transfers in drivers common layer includes certain error checks and argument validation that don't belong there, considering how the Mesa codebase is laid out. These are higher level validations that, if necessary, should be performed earlier (i.e, in GL API entry points). This patch simply removes these error checks from driver code.

* meta: Fix the y offset for 1D_ARRAY in _mesa_meta_pbo_TexSubImageNeil Roberts2015-03-051-0/+8

* meta: Allow GL_UN/PACK_IMAGE_HEIGHT in _mesa_meta_pbo_Get/TexSubImageNeil Roberts2015-03-051-12/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that a layered source PBO is interpreted as a single tall 2D image it's quite easy to accept the image height packing option by just creating an image that is tall enough to include the image padding. I'm not sure whether the image height property should affect 1D_ARRAY textures. My intuition and interpretation of the GL spec (which is a bit vague) would be that it shouldn't. However the software fallback path in Mesa uses the property for packing but not for unpacking. The binary NVidia driver uses it for both. This patch doesn't use it for either case so it is different from the software fallback. There is some discussion about this here: http://lists.freedesktop.org/archives/mesa-dev/2015-February/077925.html This is tested by the texsubimage Piglit test with the array and pbo arguments. Previously this test was skipping this code path because it always sets the image height. I've also tested it by modifying the getteximage-targets test. It wasn't using this code path before because it was using the default texture object so this code couldn't successfully create a frame buffer. I also modified it to add some image padding with the image height in the PBO. Reviewed-by: Jason Ekstrand <[email protected]> Cc: "10.5" <[email protected]>
* Revert "common: Fix PBOs for 1D_ARRAY."Neil Roberts2015-03-051-36/+26
| | | | | | | | | | | | | | | | | | This reverts commit 546aba143d13ba3f993ead4cc30b2404abfc0202. I think the changes to the calls to glBlitFramebuffer from this patch are no different to what it was doing previously because it used to set height to 1 before doing the blits. However it was introducing some problems with the blit for layer 0 because this was no longer special cased. It didn't fix problems with the yoffset which needs to be interpreted as a slice offset. I think a better solution would be to modify the original if statement to cope with the yoffset.

* meta: Fix saving the results of the current occlusion queryNeil Roberts2015-02-161-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | When restoring the current state in _mesa_meta_end it was previously trying to copy the on-going sample count of the current occlusion query into the new query after restarting it so that the driver will continue adding to the previous value. This wouldn't work for two reasons. Firstly, the query might not be ready yet so the Result member will usually be zero. Secondly the saved query is stored as a pointer to the query object, not a copy of the struct, so it is actually restarting the exact same object. Copying the result value is just copying between identical addresses with no effect. The call to _mesa_BeginQuery will have always reset it back to zero. This patch fixes it by making it actually wait for the query object to be ready before grabbing the previous result. The downside of doing this is that it could introduce a stall but I think this situation is unlikely so it might not matter too much. A better solution might be to introduce a real suspend/resume mechanism to the driver interface. This could be implemented in the i965 driver by saving the depth count multiple times like it does in the i945 driver.

| | | | | | | | | | | | | | In order to implement ARB_DIRECT_STATE_ACCESS, many GL API functions must now rely on a backend that both traditional and DSA functions can use. For instance, _mesa_TexStorage2D and _mesa_TextureStorage2D both call a backend function _mesa_texture_storage that takes a context and a texture object as arguments. The backend is named _mesa_texture_storage so that Meta can call it and avoid looking up the context and the texture object. However, backend names often look very close to the names of software fallbacks (ie. _mesa_alloc_texture_storage). For this reason, software fallbacks have been renamed for clarity to have the form _mesa_[Driver function name]_sw. Reviewed-by: Anuj Phogat <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extension enables doing a multisample buffer resolve and buffer scaling using a single glBlitFrameBuffer() call. Currently, we have this extension implemented in BLORP which is only used by SNB and IVB. This patch implements the extension in meta path which makes it available to Broadwell. Implementation features: - Supports scaled resolves of 2X, 4X and 8X multisample buffers. - Avoids unnecessary shader compilations by storing the pre compiled shaders for each supported sample count. - Uses bilinear filtering for both GL_SCALED_RESOLVE_FASTEST_EXT and GL_SCALED_RESOLVE_NICEST_EXT filter options. This is an allowed behavior in the extension's spec. - I tried doing bicubic filtering for GL_SCALED_RESOLVE_NICEST_EXT filter. It made the edges in the image look little smoother but the image gets blurred causing no overall quality improvement. For now I have dropped the idea of doing different filtering for nicest filter. V2: - Minor changes to simplify the fragment shader. - Refactor the code to move i965 specific sample_map computation out of Meta. We now use ctx->Const.SampleMap{2,4,8}x variables initialized by the driver. - Use a simple msaa resolve shader for scaled resolves with scaling factor = 1.0. V3: - Make changes to create a string out of ctx->Const.SampleMap{2,4,8}x variables and use it in fragment shader. V4: - Make changes to use uint8_t type ctx->Const.SampleMap{2,4,8}x variables.
