Note for reviewers: I've carefully considered the best name for this file and this was my best option (other possibilities were intel_lr_context.c or intel_execlist.c). I am open to a certain bikeshedding on this matter, anyway. Regarding splitting execlists and logical ring contexts, it is probably not worth it for the moment. v2: Change to intel_lrc.c Signed-off-by: Oscar Mateo --- drivers/gpu/drm/i915/Makefile | 1 + drivers/gpu/drm/i915/intel_lrc.c | 42 ++++++++++++++++++++++++++++++++++++++++ 2 files changed, 43 insertions(+) create mode 100644 drivers/gpu/drm/i915/intel_lrc.c diff --git a/drivers/gpu/drm/i915/Makefile b/drivers/gpu/drm/i915/Makefile index b1445b7..428cff9 100644 --- a/drivers/gpu/drm/i915/Makefile +++ b/drivers/gpu/drm/i915/Makefile @@ -29,6 +29,7 @@ i915-y += i915_cmd_parser.o \ i915_gpu_error.o \ i915_irq.o \ i915_trace_points.o \ + intel_lrc.o \ intel_ringbuffer.o \ intel_uncore.o diff --git a/drivers/gpu/drm/i915/intel_lrc.c b/drivers/gpu/drm/i915/intel_lrc.c new file mode 100644 index 0000000..49bb6fc --- /dev/null +++ b/drivers/gpu/drm/i915/intel_lrc.c @@ -0,0 +1,42 @@ +/* + * Copyright © 2014 Intel Corporation + * + * 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.
