Subject: radv: don't expose linear depth surfaces on SI/CIK/VI either.
X-Git-Tag: upstream/19.0.0~2791
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c1ba33c34b804ddce2de18ca3c13611202d8e38b;p=platform%2Fupstream%2Fmesa.git

radv: don't expose linear depth surfaces on SI/CIK/VI either.

ac_surface.c: gfx6_compute_surface says
/* DB doesn't support linear layouts. */

Now if we expose linear depth and create a linear depth image
and use CmdCopyImage to copy into it, we can't map the underlying
memory and read it linearly which I think should work.
