From 23105541727cd6b702c9ee66d98ba50a129fbd5e Mon Sep 17 00:00:00 2001 From: James Zhu Date: Tue, 25 Apr 2023 16:55:56 -0400 Subject: drm/amdgpu: save/restore part of xcp drm_device fields Redirect xcp allocated drm_device::rdev/pdev/driver with amdgpu pci_device/drm_device setting. They need be saved before redirect and restored after unregister xcp drm_device. -v2: fix warning discarded-qualifiers Signed-off-by: James Zhu Acked-by: Alex Deucher Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_xcp.c | 16 ++++++++++++++-- drivers/gpu/drm/amd/amdgpu/amdgpu_xcp.h | 4 ++++ 2 files changed, 18 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_xcp.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_xcp.c index fcdc0862d258..86087faab689 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_xcp.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_xcp.c @@ -240,9 +240,14 @@ static int amdgpu_xcp_dev_alloc(struct amdgpu_device *adev) return PTR_ERR(p_ddev); /* Redirect all IOCTLs to the primary device */ + adev->xcp_mgr->xcp[i].rdev = p_ddev->render->dev; + adev->xcp_mgr->xcp[i].pdev = p_ddev->primary->dev; + adev->xcp_mgr->xcp[i].driver = (struct drm_driver *)p_ddev->driver; + adev->xcp_mgr->xcp[i].vma_offset_manager = p_ddev->vma_offset_manager; p_ddev->render->dev = ddev; p_ddev->primary->dev = ddev; p_ddev->vma_offset_manager = ddev->vma_offset_manager; + p_ddev->driver = &amdgpu_partition_driver; adev->xcp_mgr->xcp[i].ddev = p_ddev; } @@ -330,13 +335,20 @@ int amdgpu_xcp_dev_register(struct amdgpu_device *adev, void amdgpu_xcp_dev_unplug(struct amdgpu_device *adev) { + struct drm_device *p_ddev; int i; if (!adev->xcp_mgr) return; - for (i = 0; i < MAX_XCP; i++) - drm_dev_unplug(adev->xcp_mgr->xcp[i].ddev); + for (i = 0; i < MAX_XCP; i++) { + p_ddev = adev->xcp_mgr->xcp[i].ddev; + drm_dev_unplug(p_ddev); + p_ddev->render->dev = adev->xcp_mgr->xcp[i].rdev; + p_ddev->primary->dev = adev->xcp_mgr->xcp[i].pdev; + p_ddev->driver = adev->xcp_mgr->xcp[i].driver; + p_ddev->vma_offset_manager = adev->xcp_mgr->xcp[i].vma_offset_manager; + } } int amdgpu_xcp_open_device(struct amdgpu_device *adev, diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_xcp.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_xcp.h index 9c5912b9d8bd..0f8026d64ea5 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_xcp.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_xcp.h @@ -77,6 +77,10 @@ struct amdgpu_xcp { bool valid; atomic_t ref_cnt; struct drm_device *ddev; + struct drm_device *rdev; + struct drm_device *pdev; + struct drm_driver *driver; + struct drm_vma_offset_manager *vma_offset_manager; struct amdgpu_sched gpu_sched[AMDGPU_HW_IP_NUM][AMDGPU_RING_PRIO_MAX]; }; -- cgit v1.2.3
