* i965: Rename pixel_scoreboard_clear to last_render_target for clarity.Kenneth Graunke2011-10-185-16/+16
| | | | | | | | | | | | | | | | | Finding this bit in the documentation proved challenging. It wasn't in the SEND instruction's message descriptor section, nor the data port message descriptor section. It turns out to be part of the Render Target Write message's control bits, and in the documentation is named "Last Render Target Select". Shaders that use Multiple Render Targets should set this bit on the last RT write, but not on any prior ones. The GPU does update the Pixel Scoreboard appropriately, but doesn't document this bit as directly causing a scoreboard clear.

* i965: Remove duplicate copies of mlen & rlen from instruction decode.Kenneth Graunke2011-10-181-13/+4
| | | | | | | | | | | | | | | | | After printing the details of a specific message, we always print out the message length and response length with nice "mlen" and "rlen" labels. For Gen5+ URB writes, we were dumping mlen and rlen a second time: urb 0 urb_write interleave used complete mlen 5, rlen 0 mlen 5 rlen 0 Also, for Gen6 data port messages, we were including mlen and rlen in the tuple of undecipherable integers. Both of these are completely redundant. So, remove them. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Eric Anholt <[email protected]>
* i965: Factor out code for setting Message Descriptors.Kenneth Graunke2011-10-181-129/+77
| | | | | | | | | | | | | | | | | | Every brw_set_???_message function had duplicated code, per-generation, to set the Message Descriptor and Extended Message Descriptor bits (SFID, message length, response length, header present, end of thread). However, these fields are actually specified as part of the SEND instruction itself; individual types of messages don't even specify them (except for header present, but that's in the same bit location). Since these are exactly the same regardless of the message type, just create a function to set them, using the generic message structs. This not only shortens the code, but hides a lot of the per-generation complexity (like the SFID being in destreg__conditionalmod) in one spot.

* i965: Remove EOT parameter from brw_SAMPLE and brw_set_sampler_message.Kenneth Graunke2011-10-184-13/+5
| | | | | | | | | | | | | The existing code asserted that eot == 0, as it doesn't make sense for a thread to sample a texture as the last thing it does. It doesn't make much sense to pass around a dead parameter either. Especially for a function which already has a long parameter list. So, remove the parameter and just set EOT to 0.

| | | | | | | | | | | | | | | When reading the data port code, it was not clear to me what these values meant, nor where I could find them in the documentation. Especially since the latest BSpec and older PRMs document them in radically different places...neither of which are near the descriptions of individual messages. Cite the documentation, and rename them to SFID to signify that these are Shared Function IDs that one can read about in the GPU overview, rather than arbitrary bitfields. While we're add it, make them an enum. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Eric Anholt <[email protected]>
* i965: Clarify check for which cache to use on Gen6 data port reads.Kenneth Graunke2011-10-181-3/+3
| | | | | | | | | | | | | | Currently, we use the Render Cache for scratch access (read/write data) and the Sampler Cache for all read only data (pull constants). Reversing the condition here is clearer: if the caller requested the Render Cache, use that. Otherwise, they requested the Data Cache (which does not exist on Gen6) or Sampler Cache, so use the Sampler Cache. This should not change behavior in any way.

* glsl: Stop tree grafting if a variable is overwritten as an 'out' param.Kenneth Graunke2011-10-181-11/+28
| | | | | | | | | | | | | | | While reviewing some compiler cleanups I'd sent out, Paul noticed that tree grafting wasn't taking "out" parameters into account. Further investigation revealed that it isn't strictly necessary: ir_call ends basic blocks, and tree grafting currently only operates on basic blocks. So calls already kill grafts. However, just to be safe, this patch makes "out" parameters explicitly kill grafts. Paul and I both prefer this. It's a bit clearer.

* vbo: Redeclare bind_array() as non-static vbo_bind_array()Chad Versace2011-10-182-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is necessary because i965 will need to call vbo_bind_array() when cleaning up after a buffer resolve meta-op. Detailed Explanation -------------------- The vbo module tracks vertex attributes separately from the gl_context. Specifically, the vbo module maintins vertex attributes in vbo_exec_context::array::inputs, which is synchronized with gl_context::Array::ArrayObj::VertexAttrib by vbo_bind_array(). vbo_draw_arrays() calls vbo_bind_array() to perform the synchronization before calling the real draw call, vbo_context::draw_arrays. Intel hardware accomplishes buffer resolves with a meta-op. Frequently, that meta-op must be performed within glDraw* in the moment immediately before the draw occurs (The hardware designers hate us...). After performing the meta-op, but before calling vbo_bind_array(), the gl_context's vertex attributes will have been restored to their original state (that is, their state before the meta-op began), but the vbo module's vertex attribute are those used in the last meta-op. Therefore we must manually synchronize the two with vbo_bind_array() before continuing with the original draw command (that is, the one requested with glDraw*). See brw_predraw_resolve_buffers(), which will be added in a future commit. Reviewed-by: Brian Paul <[email protected]> Signed-off-by: Chad Versace <[email protected]>
* mesa: Add dd_function_table::PrepareExecBeginChad Versace2011-10-183-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This hook allows the driver to prepare for a glBegin/glEnd. i965 will use the hook to avoid avoid recursive calls to FLUSH_VERTICES during a buffer resolve meta-op. Detailed Justification ---------------------- When vertices are queued during a glBegin/glEnd block, those vertices must of course be drawn before any rendering state changes. To enusure this, Mesa calls FLUSH_VERTICES as a prehook to such state changes. Therefore, FLUSH_VERTICES itself cannot change rendering state without falling into a recursive trap. This precludes meta-ops, namely i965 buffer resolves, from occuring while any vertices are queued. To avoid that situation, i965 must satisfy the following condition: that it queues no vertex if a buffer needs resolving. To satisfy this, i965 will use the PrepareExecBegin hook to resolve all buffers on entering a glBegin/glEnd block. -------- v2: Don't add dd_function_table::CleanupExecEnd. Anholt and I discovered that hook to be unnecessary. Reviewed-by: Brian Paul <[email protected]> Signed-off-by: Chad Versace <[email protected]>
* swrast: Fix fastpaths for glRead/WritePixels(GL_DEPTH_STENCIL)Chad Versace2011-10-182-0/+4
| | | | | | | | | | | | | | | | | | | In some cases, Intel hardware requires that depth and stencil buffers be separate. To accommodate swrast, i965 resorts to hackery that causes a segfault in the fastpaths of draw_depth_stencil_pixels() and read_depth_stencil_pixels(). The hack is that i965 sets framebuffer->Attachment[BUFFER_DEPTH].Renderbuffer and framebuffer->Attachment[BUFFER_STENCIL].Renderbuffer to a dummy renderbuffer for which the GetRow accessors and friends are null. The real buffers are located at framebuffer->_DepthBuffer and framebuffer->_Stencilbuffer. To fix the segault, this patch skips the fastpath if framebuffer->Attachment[BUFFER_DEPTH].Renderbuffer->GetRow is null. Note: This is a candidate for the 7.11 branch.
