From 525921ed51176255474c73adacfc6801a7bf2783 Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Sat, 4 Jul 2015 14:10:21 +0200 Subject: gallium/ddebug: new pipe for hang detection and driver state dumping (v2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit v2: lots of improvements This is like identity or trace, but simpler. It doesn't wrap most states. Run with: GALLIUM_DDEBUG=1000 [executable] where "executable" is the app and "1000" is in miliseconds, meaning that the context will be considered hung if a fence fails to signal in 1000 ms. If that happens, all shaders, context states, bound resources, draw parameters, and driver debug information (if any) will be dumped into: /home/$username/dd_dumps/$processname_$pid_$index. Note that the context is flushed after every draw/clear/copy/blit operation and then waited for to find the exact call that hangs. You can also do: GALLIUM_DDEBUG=always to do the dumping after every draw/clear/copy/blit operation without flushing and waiting. Examples of driver states that can be dumped are: - Hardware status registers saying which hw block is busy (hung). - Disassembled shaders in a human-readable form. - The last submitted command buffer in a human-readable form. v2: drop pipe-loader changes, drop SConscript rename dd.h -> dd_pipe.h Acked-by: Christian König Acked-by: Alex Deucher --- src/gallium/Makefile.am | 1 + 1 file changed, 1 insertion(+) (limited to 'src/gallium/Makefile.am') diff --git a/src/gallium/Makefile.am b/src/gallium/Makefile.am index e2c1090aa26..a7c3606de0a 100644 --- a/src/gallium/Makefile.am +++ b/src/gallium/Makefile.am @@ -11,6 +11,7 @@ SUBDIRS += auxiliary ## SUBDIRS += \ + drivers/ddebug \ drivers/noop \ drivers/trace \ drivers/rbug -- cgit v1.2.3
