From: Alyssa Rosenzweig Date: Fri, 8 Mar 2019 23:41:12 +0000 (+0000) Subject: panfrost: Support linear depth textures X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2df4537f911178e545e78aab9f3b37bb72438c00;p=mesa.git panfrost: Support linear depth textures This combination has not yet been seen "in the wild" in traces, but to support linear depth FBOs, ~bruteforce reveals this bit pattern is necessary. It's not yet clear why the meanings of 0x1 and 0x2 are essentially flipped (tiled vs linear for colour, linear vs some sort of tiled for depth).
