From 8d74749f812e64968d37266061293e204fea252c Mon Sep 17 00:00:00 2001 From: Alyssa Rosenzweig Date: Thu, 27 Jun 2019 14:13:10 -0700 Subject: panfrost: Implement instanced rendering We implement GLES3.0 instanced rendering with full support for instanced arrays (via instance divisors). To do so, we use the new invocation helpers to invoke a triplet of (1, vertex_count, instance_count), rather than simply (1, vertex_count, 1). We rewrite the attribute handling code into a new pan_instancing.c file which handles both the simple LINEAR case for non-instanced as well as each of the new instancing cases: MODULO (for per-vertex attributes), POT and NPOT divisors. As a side effect, we rework how vertex buffers are handled, duplicating them to be 1:1 with vertex descriptors to simplify instancing code paths dramatically. This might be a performance regression, but this remains to be seen; if so, we can always deduplicate later with some added logic in pan_instancing.c Signed-off-by: Alyssa Rosenzweig --- src/gallium/drivers/panfrost/meson.build | 1 + 1 file changed, 1 insertion(+) (limited to 'src/gallium/drivers/panfrost/meson.build') diff --git a/src/gallium/drivers/panfrost/meson.build b/src/gallium/drivers/panfrost/meson.build index 80cfee794db..b69b41bfd90 100644 --- a/src/gallium/drivers/panfrost/meson.build +++ b/src/gallium/drivers/panfrost/meson.build @@ -58,6 +58,7 @@ files_panfrost = files( 'pan_pretty_print.c', 'pan_fragment.c', 'pan_invocation.c', + 'pan_instancing.c', 'pan_scoreboard.c', 'pan_sfbd.c', 'pan_mfbd.c', -- cgit v1.2.3
