From f71364f29787d0f822474ed970c5f28bede49abb Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 2 Feb 2017 16:25:12 -0800 Subject: [PATCH] broadcom: Add vc5 CLIF dumping This will be usable with "VC5_DEBUG=cl" on the vc5 driver to stream a CLIF file (the Broadcom equivalent of i965's AUB) to stderr. I haven't tested that this is actually usable with the internal CLIF-consuming tools, but is close enough as a baseline and is useful for visually inspecting the command stream. --- src/broadcom/Makefile.sources | 2 + src/broadcom/clif/clif_dump.c | 268 ++++++++++++++++++++++++++++++++++ src/broadcom/clif/clif_dump.h | 42 ++++++ 3 files changed, 312 insertions(+) create mode 100644 src/broadcom/clif/clif_dump.c create mode 100644 src/broadcom/clif/clif_dump.h diff --git a/src/broadcom/Makefile.sources b/src/broadcom/Makefile.sources index d40febae678..626290b8000 100644 --- a/src/broadcom/Makefile.sources +++ b/src/broadcom/Makefile.sources @@ -13,6 +13,8 @@ BROADCOM_FILES = \ cle/v3d_packet_helpers.h \ common/v3d_debug.c \ common/v3d_debug.h \ + clif/clif_dump.c \ + clif/clif_dump.h \ common/v3d_device_info.h \ qpu/qpu_disasm.c \ qpu/qpu_disasm.h \ diff --git a/src/broadcom/clif/clif_dump.c b/src/broadcom/clif/clif_dump.c new file mode 100644 index 00000000000..8e9e248c0e4 --- /dev/null +++ b/src/broadcom/clif/clif_dump.c @@ -0,0 +1,268 @@ +/* + * Copyright © 2016 Broadcom + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
