* Revert "util: fix DXT1 RGBA texture compression if the source color is (0, ↵Dave Airlie2011-02-161-14/+2
| | | | | | | | 0, 0, 0)" This reverts commit 6e7d782da506da233b2ac695b022ac393e1c719e. Oops, I just had this locally for testing and forgot to remove it before pushing.
* util: fix DXT1 RGBA texture compression if the source color is (0, 0, 0, 0)Marek Olšák2011-02-161-2/+14
| | | | | | | | | This is a workaround for a bug in libtxc_dxtn. Fixes: - piglit/GL_EXT_texture_compression_s3tc/fbo-generatemipmap-formats Signed-off-by: Dave Airlie <[email protected]>
* gallium: add usage parameter to pipe_buffer_createMarek Olšák2011-02-155-1/+8
| | | | | And set a reasonable buffer usage flag everywhere instead of just PIPE_USAGE_DEFAULT.
* pb_bufmgr_cache: add is_buffer_busy hook and use it instead of non-blocking mapMarek Olšák2011-02-142-7/+14
| | | | This is cleaner and implementing the hook is optional.
* gallium: notify drivers about possible changes in user buffer contentsMarek Olšák2011-02-143-6/+15
| | | | Also implement the redefine_user_buffer hook in the drivers.
* gallium: remove pipe_vertex_buffer::max_indexMarek Olšák2011-02-148-25/+10
| | | | | This is redundant to pipe_draw_info::max_index and doesn't really fit in the optimizations I plan.
* gallium: always save and restore vertex buffers using cso_cacheMarek Olšák2011-02-147-10/+75
|
* draw: Don't define the last two mipmap levels in aa lines.José Fonseca2011-02-141-5/+11
| | | | | | Some hardware needs to make a seperate copy of all levels to obey max_lod, so simply do not define the last two levels instead of clamping.
* u_index_modify: map buffers with PIPE_TRANSFER_UNSYNCHRONIZEDMarek Olšák2011-02-141-3/+12
|
* u_vbuf_mgr: fix segfaultMarek Olšák2011-02-121-1/+1
| | | | | max_index could have been less than min_index, which later caused integer underflow followed by a segfault in memcpy.
* draw: tweak AA line texture minimum alphaBrian Paul2011-02-111-1/+1
| | | | | AA lines drawn as textured quads look a little better with this change. Conformance/piglit tests still pass.
* draw: Don't use the pipeline when drawing lines with fractional widths.José Fonseca2011-02-113-5/+6
| | | | Spotted by Jakob Bornecrantz.
* util: Define round and roundf on MSVC.José Fonseca2011-02-111-1/+13
|
* u_upload_mgr: Use PIPE_TRANSFER_FLUSH_EXPLICIT.José Fonseca2011-02-101-2/+9
| | | | This can avoid DMAing the whole buffer when just a fraction was changed.
* u_blitter: let the driver check whether there's a recursionMarek Olšák2011-02-102-6/+9
|
* u_vbuf_mgr: add a way to specify the BIND flag for the upload bufferMarek Olšák2011-02-082-1/+3

* util: import a new vertex buffer managerMarek Olšák2011-02-074-1/+722
| | | | | | | This code has originally matured in r300g and was ported to r600g several times. It was obvious it's a code duplication. See also comments in the header file.
* util: Change u_get_transfer_vtbl usage argument type to match prototype.Vinson Lee2011-02-031-1/+1
| | | | | | The type of u_get_transfer_vtbl of the usage argument in u_transfer.h is unsigned and not enum pipe_transfer_usage. This patch changes the type of usage to unsigned to match the prototype in the header file.
* cso: don't tell drivers to bind null samplers, sampler viewsBrian Paul2011-02-031-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before, the set_sampler_views() and restore_sampler_views() functions used MAX2(old,new) to tell the driver how many samplers or sampler views to set. This could result in cases such as: pipe->set_fragment_sampler_views(pipe, 4, views={foo, bar, NULL, NULL}) Many/most gallium drivers would take this as-is and set ctx->num_sampler_views=4 and ctx->sampler_views={foo, bar, NULL, NULL, ...}. Later, loops over ctx->num_sampler_views would have to check for null pointers. Worse, the number of sampler views and number of sampler CSOs could get out of sync: ctx->num_samplers = 2 ctx->samplers = {foo, bar, ...} ctx->num_sampler_views = 4 ctx->sampler_views={Foo, Bar, NULL, NULL, ...} So loops over the num_samplers could run into null sampler_views pointers or vice versa. This fixes a failed assertion in the SVGA driver when running the Mesa engine demo in AA line mode (and possibly other cases). It looks like all gallium drivers are careful to unreference views and null-out sampler CSO pointers for the units beyond what's set with the pipe::bind_x_sampler_states() and pipe::set_x_sampler_views() functions. I'll update the gallium docs to explain this as well.
* util: Prevent transfer dangling pointer on map failure.José Fonseca2011-02-031-0/+1

* cso: refactor texture sampler and sampler view codeBrian Paul2011-02-021-326/+307
| | | | | | This consolidates the code duplicated between the fragment sampler and vertex sampler functions. Plus, it'll make adding support for geometry shader samplers trivial.
* cso: rename fragment sampler-related fieldsBrian Paul2011-02-021-21/+26
| | | | To better distinguish from vertex sampler fields.
* cso: fix loop bound in cso_set_vertex_samplers()Brian Paul2011-02-021-1/+1
| | | | | | | Before we were looping to nr_samplers, which is the number of fragment samplers, not vertex samplers. NOTE: This is a candidate for the 7.9 and 7.10 branches.
* util: Call tables should be const.Henri Verbeet2011-01-301-1/+1

* u_blitter: use user buffers instead of real buffersMarek Olšák2011-01-291-21/+8
| | | | User buffers may be the fastest way to upload data.
* util: Fix leak of transfers in upload managerJakob Bornecrantz2011-01-281-0/+1

* util: fix parsing debug optionsMarek Olšák2011-01-271-19/+25
| | | | | | | So that 'foo' can be found in: OPTION=prefixfoosuffix,foo Also allow that debug options can be separated by a non-alphanumeric characters instead of just commas.
* r300g: fix some bugs with zbuffer compression (v4)Marek Olšák2011-01-273-40/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This drops the memblock manager for ZMASK. Instead, only one zbuffer can be compressed at a time. Note that this does not necessarily have to be slower. When there is a large number of zbuffers, compression might be used more often than it was before. It's also easier to debug. How it works: 1) 'clear' turns the compression on. 2) If some other zbuffer is set or the currently-bound zbuffer is used for texturing, the driver decompresses it and then turns the compression off. Notes: - The ZMASK clear has been refactored, so that only one packet3 is used to clear ZMASK. - The 8x8 compression mode is disabled. I couldn't make it work without issues. - Also removed driver-specific stuff from u_blitter. Driver status: - RV530 and R580 appear to just work (finally). - RV570 should work, but there may be an issue that we don't correctly calculate the number of dwords to clear, resulting in a partially uninitialized zbuffer. - RS690 misrenders as if no ZMASK clear happened. No idea what's going on. - RV350 may even hardlock. This issue was already present and this patch doesn't fix it. I think we are still missing some hardware info we need to make the zbuffer compression work fully. Note that there is also an issue with HiZ, resulting in a sort of blocky zigzagged corruption around some objects.
* tgsi: add cases for array texturesBrian Paul2011-01-261-0/+2
| | | | Fixes http://bugs.freedesktop.org/show_bug.cgi?id=33555
* util: require debug options to be separated by commasMarek Olšák2011-01-261-1/+38
| | | | | | | | | Let's assume there are two options with names such that one is a substring of another. Previously, if we only specified the longer one as a debug option, the shorter one would be considered specified as well (because of strstr). This commit fixes it by checking that each option is surrounded by commas. (a regexp would be nicer, but this is not a performance critical code)

* u_blitter: remove bogus assertionMarek Olšák2011-01-251-3/+0
| | | | The module uses the 3D engine, so it can blit non-compatible formats.

* gallium: implement modern sampling schemeZack Rusin2011-01-2412-33/+607
| | | | | | | | | | | largely a merge of the previously discussed origin/gallium-resource-sampling but updated. the idea is to allow arbitrary binding of resources, the way opencl, new gl versions and dx10+ require, i.e. DCL RES[0], 2D, FLOAT LOAD DST[0], SRC[0], RES[0] SAMPLE DST[0], SRC[0], RES[0], SAMP[0]
* draw: Do not use LLVM's opaque types.José Fonseca2011-01-241-1/+1
| | | | | | | | | | | | | | | | | | | | | Contrary what the name may suggest, LLVM's opaque types are used for recursive types -- types whose definition refers itself -- so opaque types correspond to pre-declaring a structure in C. E.g.: struct node; struct link { .... struct node *next; }; struct node { struct link link; } Void pointers are also disallowed by LLVM. So the suggested way of creating what's commonly referred as "opaque pointers" is using byte pointer (i.e., uint8_t * ).

| | | | | | The new function, pipe_get_tile_rgba_format(), no longer takes a swizzle (we weren't actually using it anywhere). Rename it to indicate that the format is passed explicitly.
