From: Alyssa Rosenzweig Date: Thu, 22 Aug 2019 20:09:00 +0000 (-0700) Subject: pan/decode: Remove size/stride divisibility check X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=caec0b32320de68c35a3f02dd2ef1e8f37de928c;p=mesa.git pan/decode: Remove size/stride divisibility check The hardware doesn't care, and a lot of Panfrost code relies on an oversized buffer. The important part is that (stride * padded_num_vertices) is no greater than size, which we'll need to check once we validate instancing.
