From bff77e86a3776fab6859bc168ecda6ccf56bfbd2 Mon Sep 17 00:00:00 2001 From: Le Ma Date: Fri, 25 Oct 2019 17:48:52 +0800 Subject: [PATCH] drm/amdgpu: bypass some cleanup work after err_event_athub (v2) PSP lost connection when err_event_athub occurs. These cleanup work can be skipped in BACO reset. v2: squash in missing include (Alex) Signed-off-by: Le Ma Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 6 ++++++ drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c | 9 +++++++++ drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c | 20 +++++++++++--------- drivers/gpu/drm/amd/amdgpu/gfx_v9_0.c | 6 ++++-- 4 files changed, 30 insertions(+), 11 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c index c03089503b0f..d36d2b093539 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c @@ -2271,6 +2271,12 @@ static int amdgpu_device_ip_suspend_phase2(struct amdgpu_device *adev) /* displays are handled in phase1 */ if (adev->ip_blocks[i].version->type == AMD_IP_BLOCK_TYPE_DCE) continue; + /* PSP lost connection when err_event_athub occurs */ + if (amdgpu_ras_intr_triggered() && + adev->ip_blocks[i].version->type == AMD_IP_BLOCK_TYPE_PSP) { + adev->ip_blocks[i].status.hw = false; + continue; + } /* XXX handle errors */ r = adev->ip_blocks[i].version->funcs->suspend(adev); /* XXX handle errors */ diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c index fd7a73f4fa70..bbe9ac7e843f 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c @@ -34,6 +34,8 @@ #include "psp_v11_0.h" #include "psp_v12_0.h" +#include "amdgpu_ras.h" + static void psp_set_funcs(struct amdgpu_device *adev); static int psp_early_init(void *handle) @@ -167,6 +169,13 @@ psp_cmd_submit_buf(struct psp_context *psp, while (*((unsigned int *)psp->fence_buf) != index) { if (--timeout == 0) break; + /* + * Shouldn't wait for timeout when err_event_athub occurs, + * because gpu reset thread triggered and lock resource should + * be released for psp resume sequence. + */ + if (amdgpu_ras_intr_triggered()) + break; msleep(1); amdgpu_asic_invalidate_hdp(psp->adev, NULL); } diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c index 796326b36e00..dab90c280476 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c @@ -558,15 +558,17 @@ int amdgpu_ras_feature_enable(struct amdgpu_device *adev, if (!(!!enable ^ !!amdgpu_ras_is_feature_enabled(adev, head))) return 0; - ret = psp_ras_enable_features(&adev->psp, &info, enable); - if (ret) { - DRM_ERROR("RAS ERROR: %s %s feature failed ret %d\n", - enable ?
