* i965: Don't check for format differences when using the blorp blitterNeil Roberts2014-08-111-54/+12
| | | | | | | | | | | | | | Previously the blorp blitter wouldn't be used if the source and destination buffer had a different format other than swizzling between RGB and BGR and adding or removing a dummy alpha channel. However there's no reason why the blorp code path can't be used to do almost all format conversions so this patch just removes the checks. However it does explicitly disable converting to/from MESA_FORMAT_Z24_UNORM_X8_UINT because there is a similar check brw_blorp_copytexsubimage. This doesn't cause any Piglit test regressions at least on Ivybridge. Reviewed-by: Kenneth Graunke <[email protected]>

* i965/eu: Refactor jump distance scaling to use a helper function.Kenneth Graunke2014-08-103-17/+32
| | | | | | | | | | | | | | | | | | | Different generations of hardware measure jump distances in different units. Previously, every function that needed to set a jump target open coded this scaling, or made a hardcoded assumption (i.e. just used 2). Most functions start with the number of instructions to jump, and scale up to the hardware-specific value. So, I made the function match that. Others start with a byte offset, and divide by a constant (8) to obtain the jump distance. This is actually 16 / 2 (the jump scale for Gen5-7). v2: Make the helper a static inline defined in brw_eu.h, instead of an actual function in brw_eu_emit.c (as suggested by Matt).

* i965/clip: Removing scissor atomBen Widawsky2014-08-101-2/+2
| | | | | | | | | | | | | | | | | Now that we no longer use ctx->DrawBuffer->_Xmin and related fields to program the screen-space viewport extents, we don't depend on any scissoring state. So we can drop the +_NEW_SCISSOR dependency. On GEN8, a change in scissor state does not effect anything for the clipper/sf hardware state. The hardware will always do the right thing once the viewport extents are programmed. We can therefore remove the unecessary state emission. Ken originally spotted this. v2: Reword the commit message. Remove spurious hunk. Reviewed-by: Kenneth Graunke <[email protected]>
* i965/guardband: Enable for all viewport dimensions (GEN8+)Ben Widawsky2014-08-101-10/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The goal of guardband clipping is to try to avoid 3d clipping because it is an expensive operation. When guardband clipping is disabled, all geometry that intersects the viewport is sent to the FF 3d clipper. Objects which are entirely enclosed within the viewport are said to be "trivially accepted" while those entirely outside of the viewport are, "trivially rejected". When guardband clipping is turned on the above behavior is changed such that if the geometry is within the guardband, and intersects the viewport, it skips the 3d clipper. Prior to GEN8, this was problematic if the viewport was smaller than the screen as it could allow for rendering to occur outside of the viewport. That could be mitigated if the programmer specified a scissor region which was less than or equal to the viewport - but this is not required for correctness in OpenGL. In theory you could be clever with the guardband so as not to invoke this problem. We do not do this, and have no data that suggests we should bother (nor the converse data). With viewport extents in place on GEN8, it should be safe to turn on guardband clipping for all cases While here, add a comment to the code which confused me thoroughly. v2: Update grammar in commit message. Reword comments based on Ken's suggestion. Reviewed-by: Kenneth Graunke <[email protected]>
* i965: Simplify viewport extents programming on GEN8Ben Widawsky2014-08-101-9/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Viewport extents are a 3rd rectangle that defines which pixels get discarded as part of the rasterization process. The actual pixels drawn to the screen are an intersection of the drawing rectangle, the viewport extents, and the scissor rectangle. It permits the use of guardband clipping in all cases (see later patch). The actual pixels drawn to the screen are an intersection of the drawing rectangle, the viewport extents, and the scissor rectangle. Scissor rectangle is not super important for this discussion as it should always help do the right thing provided the programmer uses it. switch (viewport dimensions, drawrect dimension) { case viewport > drawing rectangle: no effects; break; case viewport == drawing rectangle: no effects; break; case viewport < drawing rectangle: Pixels (after the viewport transformation but before expensive rastersizing and shading operations) which are outside of the viewport are discarded. } I am unable to find a test case where this improves performance, but in all my testing it doesn't hurt performance, and intuitively, it should not ever hurt performance. It also permits us to use the guardband more freely (see upcoming patch). v2: Updating commit message. v3: Commit message updates requested by Ken Reviewed-by: Kenneth Graunke <[email protected]>
