* gallium: refactor pipe_shader_state to support multiple IR'sRob Clark2016-05-111-2/+1
| | | | | | | | | | | | | | | | The goal is to allow the pipe driver to request something other than TGSI, but detect whether what is getting is TGSI vs what it requested. The pipe drivers will always have to support TGSI (and convert that into whatever it is that they prefer), but in some cases we should be able to skip the TGSI intermediate step (such as glsl->nir vs glsl->tgsi->nir). I think pipe_compute_state should get similar treatment. Currently, afaict, it has one user and one consumer, which has allowed it to be sloppy wrt. supporting alternative IR's.

* gallium: allow setting of the internal stream output offsetZack Rusin2014-03-071-1/+1
| | | | | | | | | | | | | | | | D3D10 allows setting of the internal offset of a buffer, which is in general only incremented via actual stream output writes. By allowing setting of the internal offset draw_auto is capable of rendering from buffers which have not been actually streamed out to. Our interface didn't allow. This change functionally shouldn't make any difference to OpenGL where instead of an append_bitmask you just get a real array where -1 means append (like in D3D) and 0 means do not append.

* gallium: allow choosing which colorbuffers to clearMarek Olšák2013-12-121-1/+1
| | | | | | | | | | | | | | Required for glClearBuffer, which only clears one colorbuffer attachment. Example: If the first colorbuffer is float and the second one is int: pipe->clear(pipe, PIPE_CLEAR_COLOR0, float_clear_color, ...); pipe->clear(pipe, PIPE_CLEAR_COLOR1, int_clear_color, ...); This doesn't need any driver changes yet, because all drivers just use: if (flags & PIPE_CLEAR_COLOR) .. The drivers which support GL 3.0 will have to implement it properly though.

* postprocess: handle partial intialization failures.Matthew McClure2013-06-271-5/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes segfaults observed when enabling the post processing features. When the format is not supported, or a texture cannot be created, the code must gracefully handle failure and report the error to the calling code for proper failure handling. To accomplish this the following changes were made to the filters.h prototypes: - bool return for pp_init_func - Added pp_free_func for filter specific resource destruction Fixes segfaults from backtraces: * util_destroy_blit pp_free * u_transfer_inline_write_vtbl pp_jimenezmlaa_init_run pp_init This patch also uses tgsi_alloc_tokens to allocate temporary tokens in pp_tgsi_to_state, instead of allocating the array on the stack.

* gallium: add condition parameter to render_conditionRoland Scheidegger2013-06-181-1/+1
| | | | | | | | | | | | | For conditional rendering this makes it possible to skip rendering if either the predicate is true or false, as supported by d3d10 (in fact previously it was sort of implied skip rendering if predicate is false for occlusion predicate, and true for so_overflow predicate). There's no cap bit for this as presumably all drivers could do it trivially (but this patch does not implement it for the drivers using true hw predicates, nvxx, r600, radeonsi, no change is expected for OpenGL functionality).

* gallium: add start_slot parameter to set_vertex_buffersMarek Olšák2012-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | | This allows updating only a subrange of buffer bindings. set_vertex_buffers(pipe, start_slot, count, NULL) unbinds buffers in that range. Binding NULL resources unbinds buffers too (both buffer and user_buffer must be NULL). The meta ops are adapted to only save, change, and restore the single slot they use. The cso_context can save and restore only one vertex buffer slot. The clients can query which one it is using cso_get_aux_vertex_buffer_slot. It's currently set to 0. (the Draw module breaks if it's set to non-zero) It should decrease the CPU overhead when using a lot of meta ops, but the drivers must be able to treat each vertex buffer slot as a separate state (only r600g does so at the moment). I can imagine this also being useful for optimizing some OpenGL use cases. Reviewed-by: Brian Paul <[email protected]>

* gallium: interface changes necessary to implement transform feedback (v5)Marek Olšák2011-12-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Namely: - EXT_transform_feedback - ARB_transform_feedback2 - ARB_transform_feedback_instanced The old interface was not useful for OpenGL and had to be reworked. This interface was originally designed for OpenGL, but additional changes have been made in order to make st/d3d1x support easier. The most notable change is the stream-out info must be linked with a vertex or geometry shader and cannot be set independently. This is due to limitations of existing hardware (special shader instructions must be used to write into stream-out buffers), and it's also how OpenGL works (stream outputs must be specified prior to linking shaders). Other than that, each stream output buffer has a "view" into it that internally maintains the number of bytes which have been written into it. (one buffer can be bound in several different transform feedback objects in OpenGL, so we must be able to have several views around) The set_stream_output_targets function contains a parameter saying whether new data should be appended or not. Also, the view can optionally be used to provide the vertex count for draw_vbo. Note that the count is supposed to be stored in device memory and the CPU never gets to know its value. OpenGL way | Gallium way ------------------------------------ BeginTF = set_so_targets(append_bitmask = 0) PauseTF = set_so_targets(num_targets = 0) ResumeTF = set_so_targets(append_bitmask = ~0) EndTF = set_so_targets(num_targets = 0) DrawTF = use pipe_draw_info::count_from_stream_output v2: * removed the reset_stream_output_targets function * added a parameter append_bitmask to set_stream_output_targets, each bit specifies whether new data should be appended to each buffer or not. v3: * added PIPE_CAP_STREAM_OUTPUT_PAUSE_RESUME for ARB_tfb2, note that the draw-auto subset is always required (for d3d10), only the pause/resume functionality is limited if the CAP is not advertised v4: * update gallium/docs v5: * compactified struct pipe_stream_output_info, updated dump/trace
* gallium: move clear paths from rgba to a pointer to a color union (v2)Dave Airlie2011-09-181-1/+1
| | | | | | | | | | | | | | | This moves the gallium interface for clears from using a pointer to 4 floats to a pointer to a union of float/unsigned/int values. Notes: 1. the value is opaque. 2. only when the value is used should it be interpretered according to the surface format it is going to be used with. 3. float clears on integer buffers and vice-versa are undefined. v2: fixed up vega and graw, dropped hunks that shouldn't have been in patch.
