* gallium: split transfer_inline_write into buffer and texture callbacksMarek Olšák2016-07-231-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | to reduce the call indirections with u_resource_vtbl. The worst call tree you could get was: - u_transfer_inline_write_vtbl - u_default_transfer_inline_write - u_transfer_map_vtbl - driver_transfer_map - u_transfer_unmap_vtbl - driver_transfer_unmap That's 6 indirect calls. Some drivers only had 5. The goal is to have 1 indirect call for drivers that care. The resource type can be determined statically at most call sites. The new interface is: pipe_context::buffer_subdata(ctx, resource, usage, offset, size, data) pipe_context::texture_subdata(ctx, resource, level, usage, box, data, stride, layer_stride) v2: fix whitespace, correct ilo's behavior Reviewed-by: Nicolai Hähnle <[email protected]> Acked-by: Roland Scheidegger <[email protected]>
* gallium: add PIPE_FLUSH_DEFERREDMarek Olšák2016-07-221-0/+10
| | | | | | | | | | | | | There are 2 uses: - Asynchronous flushing for multithreaded drivers. - Return a fence without flushing (mid-command-buffer fence). The driver can defer flushing until fence_finish is called. This is required to make Bioshock Infinite faster, which creates 1000 fences (flushes) per frame.

* gallium: allow setting of the internal stream output offsetZack Rusin2014-03-071-4/+5
| | | | | | | | | | | | | | | | 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.

* draw: clean up setting stream out information a bitRoland Scheidegger2013-08-271-0/+2
| | | | | | | | | | | | | | | | | In particular noone is interested in the vertex count, so drop that, and also drop the duplicated num_primitives_generated / so.primitives_storage_needed variables in drivers. I am unable for now to figure out if primitives_storage_needed in SO stats (used for d3d10) should increase if SO is disabled, though the equivalent num_primitives_generated used for OpenGL definitely should increase. In any case we were only counting when SO is active both in softpipe and llvmpipe anyway so don't pretend there's an independent num_primitives_generated counter which would count always. (This means the PIPE_QUERY_PRIMITIVES_GENERATED count will still be wrong just as before, should eventually fix this by doing either separate counting for this query or adjust the code so it always counts this even if SO is inactive depending on what's correct for d3d10.)

* gallium: fix PIPE_QUERY_TIMESTAMP_DISJOINTRoland Scheidegger2013-06-191-4/+6
| | | | | | | | | | | The semantics didn't really make sense, not really matching neither d3d9 (though the docs are all broken there) nor d3d10. So make it match d3d10 semantics, which actually gives meaning to the "disjoint" part. Drivers are fixed up in a very primitive way, I have no idea what could actually cause the counter to become unreliable so just always return FALSE for the disjoint part.

* gallium: add condition parameter to render_conditionRoland Scheidegger2013-06-181-5/+9
| | | | | | | | | | | | | 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: interface changes necessary to implement transform feedback (v5)Marek Olšák2011-12-151-20/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: extend resource_resolve to accommodate BlitFramebufferChristoph Bumiller2011-08-041-1/+8
| | | | | | | | | | | | | Resolve via glBlitFramebuffer allows resolving a sub-region of a renderbuffer to a different location in any mipmap level of some other texture, and, with a new extension, even scaling. Therefore, location and size parameters are needed. The mask parameter was added because resolving only depth or only stencil of a combined buffer is possible as well. Full information about the blit operation allows the drivers to take the most efficient path they possibly can.
