If needed, we can use this trick for blits too, but not for scaled blits. + 4 piglits Reviewed-by: Michel Dänzer <[email protected]> --- src/gallium/drivers/radeonsi/si_blit.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/src/gallium/drivers/radeonsi/si_blit.c b/src/gallium/drivers/radeonsi/si_blit.c index c892623..61ca2a8 100644 --- a/src/gallium/drivers/radeonsi/si_blit.c +++ b/src/gallium/drivers/radeonsi/si_blit.c @@ -522,7 +522,9 @@ void si_resource_copy_region(struct pipe_context *ctx, src_box = &sbox; src_force_level = src_level; - } else if (!util_blitter_is_copy_supported(sctx->blitter, dst, src)) { + } else if (!util_blitter_is_copy_supported(sctx->blitter, dst, src) || + /* also *8_SNORM has precision issues, use UNORM instead */ + util_format_is_snorm(src->format)) { if (util_format_is_subsampled_422(src->format)) { src_templ.format = PIPE_FORMAT_R8G8B8A8_UINT; dst_templ.format = PIPE_FORMAT_R8G8B8A8_UINT; _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
