From 57ea8c7b4d831caac27631329507baf2fbe094ae Mon Sep 17 00:00:00 2001 From: Shaoyun Liu Date: Wed, 5 Jul 2017 10:56:14 -0400 Subject: [PATCH] drm/amdgpu: NO KIQ usage on nbio hdp flush routine nbio hdp flush routine are called within atomic context. Avoid use KIQ when write to the HDP_MEM_COHERENCY_FLUSH_CNTL register since this register has its own VF copy Signed-off-by: Shaoyun Liu Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/nbio_v6_1.c | 2 +- drivers/gpu/drm/amd/amdgpu/nbio_v7_0.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/nbio_v6_1.c b/drivers/gpu/drm/amd/amdgpu/nbio_v6_1.c index 1e272f7..61c0028 100644 --- a/drivers/gpu/drm/amd/amdgpu/nbio_v6_1.c +++ b/drivers/gpu/drm/amd/amdgpu/nbio_v6_1.c @@ -67,7 +67,7 @@ void nbio_v6_1_mc_access_enable(struct amdgpu_device *adev, bool enable) void nbio_v6_1_hdp_flush(struct amdgpu_device *adev) { - WREG32_SOC15(NBIO, 0, mmBIF_BX_PF0_HDP_MEM_COHERENCY_FLUSH_CNTL, 0); + WREG32_SOC15_NO_KIQ(NBIO, 0, mmBIF_BX_PF0_HDP_MEM_COHERENCY_FLUSH_CNTL, 0); } u32 nbio_v6_1_get_memsize(struct amdgpu_device *adev) diff --git a/drivers/gpu/drm/amd/amdgpu/nbio_v7_0.c b/drivers/gpu/drm/amd/amdgpu/nbio_v7_0.c index aa04632..11b70d6 100644 --- a/drivers/gpu/drm/amd/amdgpu/nbio_v7_0.c +++ b/drivers/gpu/drm/amd/amdgpu/nbio_v7_0.c @@ -65,7 +65,7 @@ void nbio_v7_0_mc_access_enable(struct amdgpu_device *adev, bool enable) void nbio_v7_0_hdp_flush(struct amdgpu_device *adev) { - WREG32_SOC15(NBIO, 0, mmHDP_MEM_COHERENCY_FLUSH_CNTL, 0); + WREG32_SOC15_NO_KIQ(NBIO, 0, mmHDP_MEM_COHERENCY_FLUSH_CNTL, 0); } u32 nbio_v7_0_get_memsize(struct amdgpu_device *adev) -- 2.7.4
