From fbeb661bfa895dc14ea1f093edc5e6e80f1b6a95 Mon Sep 17 00:00:00 2001 From: Yair Shachar Date: Wed, 20 May 2015 13:48:26 +0300 Subject: drm/amdkfd: Add skeleton H/W debugger module support This patch adds the skeleton H/W debugger module support. This code enables registration and unregistration of a single HSA process at a time. The module saves the process's pasid and use it to verify that only the registered process is allowed to execute debugger operations through the kernel driver. v2: rename get_dbgmgr_mutex to kfd_get_dbgmgr_mutex to namespace it Signed-off-by: Yair Shachar Signed-off-by: Oded Gabbay --- drivers/gpu/drm/amd/amdkfd/kfd_pm4_headers_diq.h | 290 +++++++++++++++++++++++ 1 file changed, 290 insertions(+) create mode 100644 drivers/gpu/drm/amd/amdkfd/kfd_pm4_headers_diq.h (limited to 'drivers/gpu/drm/amd/amdkfd/kfd_pm4_headers_diq.h') diff --git a/drivers/gpu/drm/amd/amdkfd/kfd_pm4_headers_diq.h b/drivers/gpu/drm/amd/amdkfd/kfd_pm4_headers_diq.h new file mode 100644 index 0000000..a0ff348 --- /dev/null +++ b/drivers/gpu/drm/amd/amdkfd/kfd_pm4_headers_diq.h @@ -0,0 +1,290 @@ +/* + * Copyright 2014 Advanced Micro Devices, Inc. + * + * 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 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.
