From: Marek Olšák Date: Fri, 10 Jul 2015 22:17:48 +0000 (+0200) Subject: radeonsi: store shader disassemblies in memory for future users X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7dd1f45bc41c4a936b0ff84400840524bb9f8871;p=mesa.git radeonsi: store shader disassemblies in memory for future users This will be used by the new ddebug pipe. I'm including it now to avoid conflicts with other patches. --- diff --git a/src/gallium/drivers/r600/evergreen_compute.c b/src/gallium/drivers/r600/evergreen_compute.c index 4c3c34cd664..d89e3de9cc6 100644 --- a/src/gallium/drivers/r600/evergreen_compute.c +++ b/src/gallium/drivers/r600/evergreen_compute.c @@ -226,7 +226,7 @@ void *evergreen_create_compute_state( } #else memset(&shader->binary, 0, sizeof(shader->binary));
