From dd73043534515c1b8bf31f78f0e9945f5d95e0e6 Mon Sep 17 00:00:00 2001 From: Jun Lei Date: Wed, 8 Aug 2018 11:53:39 -0400 Subject: [PATCH] drm/amd/display: implement DPMS DTN test v2 [why] Existing DTN infrastructure in driver is hacky. It uses implicit log names, and also incorrect escape ID. [how] - Implement using generic DTN escape ID. - Move file logging functionality from driver to to script; driver now outputs to string/buffer - Move HWSS debug functionality to separate c file - Add debug functionalty for per-block logging as CSV - Add pretty print in python Signed-off-by: Jun Lei Reviewed-by: Tony Cheng Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/display/dc/dcn10/Makefile | 2 +- .../amd/display/dc/dcn10/dcn10_hw_sequencer.c | 2 +- .../amd/display/dc/dcn10/dcn10_hw_sequencer.h | 5 + .../dc/dcn10/dcn10_hw_sequencer_debug.c | 510 ++++++++++++++++++ .../gpu/drm/amd/display/dc/inc/hw_sequencer.h | 1 + 5 files changed, 518 insertions(+), 2 deletions(-) create mode 100644 drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer_debug.c diff --git a/drivers/gpu/drm/amd/display/dc/dcn10/Makefile b/drivers/gpu/drm/amd/display/dc/dcn10/Makefile index 84f52c63d95c..032f872be89c 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn10/Makefile +++ b/drivers/gpu/drm/amd/display/dc/dcn10/Makefile @@ -22,7 +22,7 @@ # # Makefile for DCN. -DCN10 = dcn10_resource.o dcn10_ipp.o dcn10_hw_sequencer.o \ +DCN10 = dcn10_resource.o dcn10_ipp.o dcn10_hw_sequencer.o dcn10_hw_sequencer_debug.o \ dcn10_dpp.o dcn10_opp.o dcn10_optc.o \ dcn10_hubp.o dcn10_mpc.o \ dcn10_dpp_dscl.o dcn10_dpp_cm.o dcn10_cm_common.o \ diff --git a/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c b/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c index 4b8bedb625b4..051f427868ca 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c +++ b/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.c @@ -71,7 +71,6 @@ void print_microsec(struct dc_context *dc_ctx, uint32_t ref_cycle) us_x10 % frac); } - static void log_mpc_crc(struct dc *dc) { struct dc_context *dc_ctx = dc->ctx; @@ -2712,6 +2711,7 @@ static const struct hw_sequencer_funcs dcn10_funcs = { .setup_stereo = dcn10_setup_stereo, .set_avmute = dce110_set_avmute, .log_hw_state = dcn10_log_hw_state, + .get_hw_state = dcn10_get_hw_state, .wait_for_mpcc_disconnect = dcn10_wait_for_mpcc_disconnect, .ready_shared_resources = ready_shared_resources, .optimize_shared_resources = optimize_shared_resources, diff --git a/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.h b/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.h index 7139fb73e966..84d461e0ed3e 100644 --- a/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.h +++ b/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer.h @@ -46,4 +46,9 @@ void dcn10_program_pipe( struct pipe_ctx *pipe_ctx, struct dc_state *context); +void dcn10_get_hw_state( + struct dc *dc, + char *pBuf, unsigned int bufSize, + unsigned int mask); + #endif /* __DC_HWSS_DCN10_H__ */ diff --git a/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer_debug.c b/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer_debug.c new file mode 100644 index 000000000000..9288b00e49b4 --- /dev/null +++ b/drivers/gpu/drm/amd/display/dc/dcn10/dcn10_hw_sequencer_debug.c @@ -0,0 +1,510 @@ +/* + * Copyright 2016 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.
