From 19eb0ae30e3b4d712d2911d11608de69995f86dc Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20K=C3=B6nig?= Date: Fri, 31 Mar 2017 11:03:50 +0200 Subject: [PATCH] drm/amdgpu: assign VM invalidation engine manually v2 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit For Vega10 we have 18 VM invalidation engines for each VMHUB. Start to assign them manually to the rings. v2: add a BUG_ON if we use to many engines Signed-off-by: Christian König Reviewed-by: Alex Deucher Reviewed-by: Andres Rodriguez Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_ring.h | 1 + drivers/gpu/drm/amd/amdgpu/gfx_v9_0.c | 2 +- drivers/gpu/drm/amd/amdgpu/gmc_v9_0.c | 16 ++++++++++++++++ drivers/gpu/drm/amd/amdgpu/sdma_v4_0.c | 2 +- drivers/gpu/drm/amd/amdgpu/uvd_v7_0.c | 4 ++-- drivers/gpu/drm/amd/amdgpu/vce_v4_0.c | 2 +- 6 files changed, 22 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_ring.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_ring.h index de12f7549e6d9..944443c5b90a2 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_ring.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_ring.h @@ -179,6 +179,7 @@ struct amdgpu_ring { unsigned cond_exe_offs; u64 cond_exe_gpu_addr; volatile u32 *cond_exe_cpu_addr; + unsigned vm_inv_eng; #if defined(CONFIG_DEBUG_FS) struct dentry *ent; #endif diff --git a/drivers/gpu/drm/amd/amdgpu/gfx_v9_0.c b/drivers/gpu/drm/amd/amdgpu/gfx_v9_0.c index 1badd294ff186..87596e48f65d2 100644 --- a/drivers/gpu/drm/amd/amdgpu/gfx_v9_0.c +++ b/drivers/gpu/drm/amd/amdgpu/gfx_v9_0.c @@ -2959,7 +2959,7 @@ static void gfx_v9_0_ring_emit_vm_flush(struct amdgpu_ring *ring, struct amdgpu_vmhub *hub = &ring->adev->vmhub[ring->funcs->vmhub]; int usepfp = (ring->funcs->type == AMDGPU_RING_TYPE_GFX); uint32_t req = ring->adev->gart.gart_funcs->get_invalidate_req(vm_id); - unsigned eng = ring->idx; + unsigned eng = ring->vm_inv_eng; pd_addr = pd_addr | 0x1; /* valid bit */ /* now only use physical base address of PDE and valid */ diff --git a/drivers/gpu/drm/amd/amdgpu/gmc_v9_0.c b/drivers/gpu/drm/amd/amdgpu/gmc_v9_0.c index 7f5cc75f0da5d..a71521e107635 100644 --- a/drivers/gpu/drm/amd/amdgpu/gmc_v9_0.c +++ b/drivers/gpu/drm/amd/amdgpu/gmc_v9_0.c @@ -386,6 +386,22 @@ static int gmc_v9_0_early_init(void *handle) static int gmc_v9_0_late_init(void *handle) { struct amdgpu_device *adev = (struct amdgpu_device *)handle; + unsigned vm_inv_eng[AMDGPU_MAX_VMHUBS] = { 0 }; + unsigned i; + + for(i = 0; i < adev->num_rings; ++i) { + struct amdgpu_ring *ring = adev->rings[i]; + unsigned vmhub = ring->funcs->vmhub; + + ring->vm_inv_eng = vm_inv_eng[vmhub]++; + dev_info(adev->dev, "ring %u uses VM inv eng %u on hub %u\n", + ring->idx, ring->vm_inv_eng, ring->funcs->vmhub); + } + + /* Engine 17 is used for GART flushes */ + for(i = 0; i < AMDGPU_MAX_VMHUBS; ++i) + BUG_ON(vm_inv_eng[i] > 17); + return amdgpu_irq_get(adev, &adev->mc.vm_fault, 0); } diff --git a/drivers/gpu/drm/amd/amdgpu/sdma_v4_0.c b/drivers/gpu/drm/amd/amdgpu/sdma_v4_0.c index c3cf6bcadc60f..88c5d8f6f414c 100644 --- a/drivers/gpu/drm/amd/amdgpu/sdma_v4_0.c +++ b/drivers/gpu/drm/amd/amdgpu/sdma_v4_0.c @@ -1041,7 +1041,7 @@ static void sdma_v4_0_ring_emit_vm_flush(struct amdgpu_ring *ring, { struct amdgpu_vmhub *hub = &ring->adev->vmhub[ring->funcs->vmhub]; uint32_t req = ring->adev->gart.gart_funcs->get_invalidate_req(vm_id); - unsigned eng = ring->idx; + unsigned eng = ring->vm_inv_eng; pd_addr = pd_addr | 0x1; /* valid bit */ /* now only use physical base address of PDE and valid */ diff --git a/drivers/gpu/drm/amd/amdgpu/uvd_v7_0.c b/drivers/gpu/drm/amd/amdgpu/uvd_v7_0.c index dc3a2145a4528..c646570d14210 100644 --- a/drivers/gpu/drm/amd/amdgpu/uvd_v7_0.c +++ b/drivers/gpu/drm/amd/amdgpu/uvd_v7_0.c @@ -1037,7 +1037,7 @@ static void uvd_v7_0_ring_emit_vm_flush(struct amdgpu_ring *ring, struct amdgpu_vmhub *hub = &ring->adev->vmhub[ring->funcs->vmhub]; uint32_t req = ring->adev->gart.gart_funcs->get_invalidate_req(vm_id); uint32_t data0, data1, mask; - unsigned eng = ring->idx; + unsigned eng = ring->vm_inv_eng; pd_addr = pd_addr | 0x1; /* valid bit */ /* now only use physical base address of PDE and valid */ @@ -1078,7 +1078,7 @@ static void uvd_v7_0_enc_ring_emit_vm_flush(struct amdgpu_ring *ring, { struct amdgpu_vmhub *hub = &ring->adev->vmhub[ring->funcs->vmhub]; uint32_t req = ring->adev->gart.gart_funcs->get_invalidate_req(vm_id); - unsigned eng = ring->idx; + unsigned eng = ring->vm_inv_eng; pd_addr = pd_addr | 0x1; /* valid bit */ /* now only use physical base address of PDE and valid */ diff --git a/drivers/gpu/drm/amd/amdgpu/vce_v4_0.c b/drivers/gpu/drm/amd/amdgpu/vce_v4_0.c index 2ffafbe6cd80f..72d0edb9bc393 100644 --- a/drivers/gpu/drm/amd/amdgpu/vce_v4_0.c +++ b/drivers/gpu/drm/amd/amdgpu/vce_v4_0.c @@ -970,7 +970,7 @@ static void vce_v4_0_emit_vm_flush(struct amdgpu_ring *ring, { struct amdgpu_vmhub *hub = &ring->adev->vmhub[ring->funcs->vmhub]; uint32_t req = ring->adev->gart.gart_funcs->get_invalidate_req(vm_id); - unsigned eng = ring->idx; + unsigned eng = ring->vm_inv_eng; pd_addr = pd_addr | 0x1; /* valid bit */ /* now only use physical base address of PDE and valid */ -- 2.39.5
