From: Rob Clark Date: Thu, 30 Apr 2020 20:54:49 +0000 (-0700) Subject: freedreno/a6xx: don't set SP_FS_CTRL_REG0.VARYING for fragcoord X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=beb02a78;p=mesa.git freedreno/a6xx: don't set SP_FS_CTRL_REG0.VARYING for fragcoord Similar change to 5785bcc8a0ff9c5072c647337bf73f696c63cbe6. It appears on a6xx and in fact this could cause varying corruption before the FS had a chance to consume the varyings from varying storage.
