From 6df442a03d1a839242397259fa13168858c52413 Mon Sep 17 00:00:00 2001 From: Le Ma Date: Mon, 25 Apr 2022 22:19:58 +0800 Subject: [PATCH] drm/amdgpu: add new doorbell assignment table for aqua_vanjaram Four basic reasons as below to do the change: 1. number of ring expand a lot on aqua_vanjaram, and adjustment on old assignment cannot make each ring in a continuous doorbell space. 2. the SDMA doorbell index should not exceed 0x1FF on aqua_vanjaram due to regDOORBELLx_CTRL_ENTRY.BIF_DOORBELLx_RANGE_OFFSET_ENTRY field width. 3. re-design the doorbell assignment and unify the calculation as "start + ring/inst id" will make the code much concise. 4. only defining the START/END makes the table look simple v2: (Lijo) 1. replace name 2. use num_inst_per_aid/sdma_doorbell_range instead of hardcoding Signed-off-by: Le Ma Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/Makefile | 2 +- .../drm/amd/amdgpu/aqua_vanjaram_reg_init.c | 52 +++++++++++++++++++ 2 files changed, 53 insertions(+), 1 deletion(-) create mode 100644 drivers/gpu/drm/amd/amdgpu/aqua_vanjaram_reg_init.c diff --git a/drivers/gpu/drm/amd/amdgpu/Makefile b/drivers/gpu/drm/amd/amdgpu/Makefile index 594e303084c5..90f771423c94 100644 --- a/drivers/gpu/drm/amd/amdgpu/Makefile +++ b/drivers/gpu/drm/amd/amdgpu/Makefile @@ -78,7 +78,7 @@ amdgpu-y += \ vega20_reg_init.o nbio_v7_4.o nbio_v2_3.o nv.o arct_reg_init.o mxgpu_nv.o \ nbio_v7_2.o hdp_v4_0.o hdp_v5_0.o aldebaran_reg_init.o aldebaran.o soc21.o \ sienna_cichlid.o smu_v13_0_10.o nbio_v4_3.o hdp_v6_0.o nbio_v7_7.o hdp_v5_2.o lsdma_v6_0.o \ - nbio_v7_9.o + nbio_v7_9.o aqua_vanjaram_reg_init.o # add DF block amdgpu-y += \ diff --git a/drivers/gpu/drm/amd/amdgpu/aqua_vanjaram_reg_init.c b/drivers/gpu/drm/amd/amdgpu/aqua_vanjaram_reg_init.c new file mode 100644 index 000000000000..3b97bc922d4a --- /dev/null +++ b/drivers/gpu/drm/amd/amdgpu/aqua_vanjaram_reg_init.c @@ -0,0 +1,52 @@ +/* + * Copyright 2022 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.
