2010-12-02i915g: switch rendering to mipmapped textures to (x,y) offsetsDaniel Vetter
Byte offsets simply don't work with tiled render targets when using tiling bits. Luckily we can cox the hw into doing the right thing with the DRAWING_RECT command by disabling the drawing rect offset for the depth buffer. Minor fixes by Jakob Bornecrantz.

2010-12-02i915g: enable X-tiling for texturesDaniel Vetter
Tiling is rather fragile in general and results in pure blackness when unlucky. Hence add a new option to disable tiling. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Jakob Bornecrantz <wallbraker@gmail.com> Signed-off-by: Jakob Bornecrantz <wallbraker@gmail.com>
2010-12-02i915g: don't pot-align stride for tiled buffersDaniel Vetter
libdrm will do this for us, if it's required (i.e. if tiling is possible). Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Jakob Bornecrantz <wallbraker@gmail.com> Signed-off-by: Jakob Bornecrantz <wallbraker@gmail.com>
2010-12-02i915g: postpone mipmap/face offset calculationDaniel Vetter
libdrm-intel can refuse to tile buffers for various reasons. For potentially tiled buffers the stride is therefore only known after the iws->buffer_create_tiled call. Unconditionally rounding up to whatever tiling requires wastes space, so rework the code to not use tex->stride in the layout code. Luckily only the mimap/face offset calculation uses it which can easily be solved by storing an (x, y) coordinate pair. Furthermore this will be usefull later for properly supporting rendering into the different levels of tiled mipmap textures. v2: switch to nblocks(x|y): More in line with gallium and better suited for rendering into mipmap textures.

2010-12-02i915g: return tiling in iws->buffer_from_handleDaniel Vetter
This is needed to properly implement tiling flags. And the gem implemention fo buffer_from_handle already calls get_tiling, so it's for free.

2010-12-02i915g: add winsys function to create tiled buffersDaniel Vetter

2010-12-01glsl: Mark the array access for whole-array comparisons.Eric Anholt
By not doing so, the uniform contents of glsl-uniform-non-uniform-array-compare.shader_test was getting thrown out since nobody was recorded as dereferencing the array.
2010-12-01i965: Add support for loops in the VS.Eric Anholt
This follows the changes done for the FS alongside the EU emit code.
2010-12-01i965: Enable IF statements in the VS.Eric Anholt
While the actual IF instructions were fixed by Zhenyu, we were still flattening them to conditional moves.
2010-12-01i965: Add support for gen6 CONTINUE instruction emit.Eric Anholt
At this point, piglit tests for fragment shader loops are working.
2010-12-01i965: Add support for gen6 BREAK ISA emit.Eric Anholt
There are now two targets: the hop-to-end-of-block target, and the target for where to resume execution for active channels.
2010-12-01i965: Add support for gen6 DO/WHILE ISA emit.Eric Anholt
There's no more DO since there's no more mask stack, and WHILE has been shuffled like IF was.

2010-12-01r300g: disable ARB_texture_swizzle if S3TC is enabled on r3xx-onlyMarek Olšák
r3xx cannot swizzle compressed textures. r4xx+ is unaffected. NOTE: This is a candidate for the 7.9 branch.

2010-12-01glsl: Add comments to lower_jumps (from the commit message).Kenneth Graunke
This is essentially Luca's commit message, but placed at the top of the file.
2010-12-01glsl: Remove "discard" support from lower_jumps.Kenneth Graunke
The new lower_discard and opt_discard_simplification passes should handle all the necessary transformations, so lower_jumps doesn't need to support it. Also, lower_jumps incorrectly handled conditional discards - it would unconditionally truncate all code after the discard. Rather than fixing the bug, simply remove the code. NOTE: This is a candidate for the 7.9 branch.
2010-12-01glsl: Add a lowering pass to move discards out of if-statements.Kenneth Graunke
This should allow lower_if_to_cond_assign to work in the presence of discards, fixing bug #31690 and likely #31983. NOTE: This is a candidate for the 7.9 branch.
