| | | | | | | | | | | | | This reverts commit d33ef52d9db8a36900dd53f2e32db9a521ace259. This change seems to expose a bug in the 3D driver tiggered by certain apps, so revert it to keep userspace working. Reported-by: Rafael J. Wysocki <rjw@sisk.pl> Cc: Rafael J.

* drm/radeon/kms: fix tiling info on evergreenAlex Deucher2010-11-181-1/+30
| | | | | | | | | | | | We aren't currently using tiling in userspace on evergreen, but the info we currently return for the tiling info query (gb_addr_config) is no adequate for userspace tiling alignment calculations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The CS checker had some incorrect alignment requirements for 2D surfaces, this made rendering to mipmap levels that were 2D broken. Also the CB height was being worked out from the BO size, this doesn't work at all when rendering mipmap levels, instead we work out what height userspace wanted from slice max and use that to check it fits inside the BO, however the DDX send the wrong slice max for an unaligned buffer so we have to workaround for that even though its a userspace bug.

It also reports if the display scanout is currently inside the vblank area. hpos reports current horizontal pixel scanout position. vpos reports the current scanned out line as a value >= 0 in active scanout. If the scanout is inside vblank area, it reports a negative value, the number of scanlines until end of vblank aka start of active scanout, e.g., -3 == "At most 3 scanlines until end of vblank". This code is derived from radeon_pm_in_vbl(), tested on R500 and R600.
