From 3e103fc301560e99913f4b9d48691d77160ed595 Mon Sep 17 00:00:00 2001 From: Kent Russell Date: Tue, 10 Sep 2019 15:48:55 -0400 Subject: [PATCH] Revert "drm/amdgpu/nbio7.4: add hw bug workaround for vega20" This reverts commit e01f2d41895102d824c6b8f5e011dd5e286d5e8b. VG20 did not require this workaround, as the fix is in the VBIOS. Leave VG10/12 workaround as some older shipped cards do not have the VBIOS fix in place, and the kernel workaround is required in those situations Signed-off-by: Kent Russell Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/nbio_v7_4.c | 6 ------ 1 file changed, 6 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/nbio_v7_4.c b/drivers/gpu/drm/amd/amdgpu/nbio_v7_4.c index b776332d979f..238c2483496a 100644 --- a/drivers/gpu/drm/amd/amdgpu/nbio_v7_4.c +++ b/drivers/gpu/drm/amd/amdgpu/nbio_v7_4.c @@ -308,13 +308,7 @@ static void nbio_v7_4_detect_hw_virt(struct amdgpu_device *adev) static void nbio_v7_4_init_registers(struct amdgpu_device *adev) { - uint32_t def, data; - - def = data = RREG32_PCIE(smnPCIE_CI_CNTL); - data = REG_SET_FIELD(data, PCIE_CI_CNTL, CI_SLV_ORDERING_DIS, 1); - if (def != data) - WREG32_PCIE(smnPCIE_CI_CNTL, data); } static void nbio_v7_4_handle_ras_controller_intr_no_bifring(struct amdgpu_device *adev) -- 2.30.2
