* freedreno/a3xx: use INDIRECT state load for shadersRob Clark2013-09-143-8/+29
| | | | | | | | | With a debug option to force DIRECT (mainly to make it easier for capturing cmdstream dumps). Using INDIRECT for large shaders at least makes a noticable reduction in CPU load, which helps for CPU limited games. Signed-off-by: Rob Clark <[email protected]>
* freedreno: avoid stalling at ringbuffer wraparoundRob Clark2013-09-142-22/+41
| | | | | | | | | Because of how the tiling works, we can't really flush at arbitrary points very easily. So wraparound is handled by resetting to top of ringbuffer. Previously this would stall until current rendering is complete. Instead cycle through multiple ringbuffers to avoid a stall. Signed-off-by: Rob Clark <[email protected]>
* freedreno: emit markers to scratch registersRob Clark2013-09-144-0/+33
| | | | | | | | | Emit markers by writing to scratch registers in order to "triangulate" gpu lockup position from post-mortem register dump. By comparing register values in post-mortem dump to command-stream, it is possible to narrow down which DRAW_INDX caused the lockup. Signed-off-by: Rob Clark <[email protected]>

* glsl/builtins: Fix {texture1D,texture2D,shadow1D}ArrayLod availibility.Paul Berry2013-09-131-5/+5
| | | | | | | | | | | | | | These functions are defined in EXT_texture_array, which makes no mention of what shader types they should be allowed in. At the time EXT_texture_array was introduced, functions ending in "Lod" were available only in vertex shaders, however this restriction was lifted in later spec versions and extensions. We already have the function lod_exists_in_stage() for figuring out whether functions ending in "Lod" should be available, so just re-use that. Reviewed-by: Kenneth Graunke <[email protected]>

* mesa: Disallow relinking if a program is used by an active XFB object.Kenneth Graunke2013-09-123-7/+47
| | | | | | | | | | | | | | | | | Paused transform feedback objects may refer to a program other than the current program. If any active objects refer to a program, LinkProgram must reject the request to relink. The code to detect this is ugly since _mesa_HashWalk is awkward to use, but unfortunately we can't use hash_table_foreach since there's no way to get at the underlying struct hash_table (and even then, we'd need to handle locking somehow).

* i965/gs: implement EndPrimitive() functionality in the visitor.Paul Berry2013-09-112-1/+241
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to GLSL, the shader may call EndPrimitive() at any point during its execution, causing the line or triangle strip currently being output to be terminated and a new strip to be begun. This is implemented in gen7 hardware by using one control data bit per vertex, to indicate whether EndPrimitive() was called after that vertex was emitted. In order to make this work without sacrificing too much efficiency, we accumulate 32 control data bits at a time in a GRF. When we have accumulated 32 bits (or when the shader terminates), we output them to the appropriate DWORD in the control data header and reset the accumulator to 0. We have to take special care to make sure that EndPrimitive() calls that occur prior to the first vertex have no effect. Since geometry shaders that output a large number of vertices are likely to be rare, an optimization kicks in if max_vertices <= 32. In this case, we know that we can wait until the end of shader execution before any control data bits need to be output. I've tried to write the code in such a way that in the future, we can easily adapt it to output stream ID bits (which are two bits/vertex instead of one).

* i965/gen7: Add the ability to send URB_WRITE_OWORD messages.Paul Berry2013-09-113-2/+16
| | | | | | | | | | | | | | | Previously, brw_urb_WRITE() would always generate a URB_WRITE_HWORD message, we always wanted to write data to the URB in pairs of varying slots or larger (an HWORD is 32 bytes, which is 2 varying slots). In order to support geometry shader EndPrimitive functionality, we'll need the ability to write to just a single OWORD (16 byte) slot, since we'll only be outputting 32 of the control data bits at a time. So this patch adds a flag that will cause brw_urb_WRITE to generate a URB_WRITE_OWORD message. Reviewed-by: Ian Romanick <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
* i965/gen7: Allow URB_WRITE channel masks to be used.Paul Berry2013-09-112-1/+7
| | | | | | | | | | | | | | Previously, brw_urb_WRITE() would unconditionally override the channel masks in the URB_WRITE message to 0xff (indicating that all channels should be written to the URB). In order to support geometry shader EndPrimitive functionality, we'll need the ability to set the channel masks programatically, so that we can output just 32 of the control data bits at a time. So this patch adds a flag that will prevent brw_urb_WRITE() from overriding them. Reviewed-by: Ian Romanick <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
* i965/gs: Set control data header size/format appropriately for EndPrimitive().Paul Berry2013-09-117-15/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The gen7 geometry shader uses a "control data header" at the beginning of the output URB entry to store either (a) flag bits (1 bit/vertex) indicating whether EndPrimitive() was called after each vertex, or (b) stream ID bits (2 bits/vertex) indicating which stream each vertex should be sent to (when multiple transform feedback streams are in use). Fortunately, OpenGL only requires separate streams to be supported when the output type is points, and EndPrimitive() only has an effect when the output type is line_strip or triangle_strip, so it's not a problem that these two uses of the control data header are mutually exclusive. This patch modifies do_vec4_gs_prog() to determine the correct hardware settings for configuring the control data header, and modifies upload_gs_state() to propagate these settings to the hardware. In addition, it modifies do_vec4_gs_prog() to ensure that the output URB entry is large enough to contain both the output vertices *and* the control data header. Finally, it modifies vec4_gs_visitor so that it accounts for the size of the control data header when computing the offset within the URB where output vertex data should be stored.
