r600g: add htile support v16
htile is used for HiZ and HiS support and fast Z/S clears. This commit just adds the htile setup and Fast Z clear. We don't take full advantage of HiS with that patch. v2 really use fast clear, still random issue with some tiles need to try more flush combination, fix depth/stencil texture decompression v3 fix random issue on r6xx/r7xx v4 rebase on top of lastest mesa, disable CB export when clearing htile surface to avoid wasting bandwidth v5 resummarize htile surface when uploading z value. Fix z/stencil decompression, the custom blitter with custom dsa is no longer needed. v6 Reorganize render control/override update mecanism, fixing more issues in the process. v7 Add nop after depth surface base update to work around some htile flushing issue. For htile to 8x8 on r6xx/r7xx as other combination have issue. Do not enable hyperz when flushing/uncompressing depth buffer. v8 Fix htile surface, preload and prefetch setup. Only set preload and prefetch on htile surface clear like fglrx. Record depth clear value per level. Support several level for the htile surface. First depth clear can't be a fast clear. v9 Fix comments, properly account new register in emit function, disable fast zclear if clearing different layer of texture array to different value v10 Disable hyperz for texture array making test simpler. Force db_misc_state update when no depth buffer is bound. Remove unused variable, rename depth_clearstencil to depth_clear. Don't allocate htile surface for flushed depth. Something broken the cliprect change, this need to be investigated. v11 Rebase on top of newer mesa v12 Rebase on top of newer mesa v13 Rebase on top of newer mesa, htile surface need to be initialized to zero, somehow special casing first clear to not use fast clear and thus initialize the htile surface with proper value does not work in all case. v14 Use resource not texture for htile buffer make the htile buffer size computation easier and simpler. Disable preload on evergreen as its still troublesome in some case v15 Cleanup some comment and remove some left over v16 Define name for bit 20 of CP_COHER_CNTL Signed-off-by: Pierre-Eric Pelloux-Prayer <[email protected]> Signed-off-by: Alex Deucher <[email protected]> Signed-off-by: Jerome Glisse <[email protected]>
