From 9497a6a3c9bcf6fac5dc29eb2d662bc12a3db4af Mon Sep 17 00:00:00 2001 From: Alyssa Rosenzweig Date: Fri, 28 Jan 2022 12:07:41 -0500 Subject: [PATCH] pan/bi: Lower gl_PointSize to FP16 on Valhall It is unclear if FP32 point sizes are supported on Valhall -- I can't get the DDK to use them at any rate. Always lower them to FP16 and store them as FP16 for hardware use.
