From 39a2bd34c933b00f7c7ada923c212b3ff826fb5d Mon Sep 17 00:00:00 2001 From: Thomas Hellström Date: Mon, 10 Jan 2022 18:22:15 +0100 Subject: drm/i915: Use the vma resource as argument for gtt binding / unbinding MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When introducing asynchronous unbinding, the vma itself may no longer be alive when the actual binding or unbinding takes place. Update the gtt i915_vma_ops accordingly to take a struct i915_vma_resource instead of a struct i915_vma for the bind_vma() and unbind_vma() ops. Similarly change the insert_entries() op for struct i915_address_space. Replace a couple of i915_vma_snapshot members with their newly introduced i915_vma_resource counterparts, since they have the same lifetime. Also make sure to avoid changing the struct i915_vma_flags (in particular the bind flags) async. That should now only be done sync under the vm mutex. v2: - Update the vma_res::bound_flags when binding to the aliased ggtt v6: - Remove I915_VMA_ALLOC_BIT (Matthew Auld) - Change some members of struct i915_vma_resource from unsigned long to u64 (Matthew Auld) v7: - Fix vma resource size parameters to be u64 rather than unsigned long (Matthew Auld) Signed-off-by: Thomas Hellström Reviewed-by: Matthew Auld Link: https://patchwork.freedesktop.org/patch/msgid/20220110172219.107131-3-thomas.hellstrom@linux.intel.com --- drivers/gpu/drm/i915/gt/intel_engine_cs.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/gpu/drm/i915/gt/intel_engine_cs.c') diff --git a/drivers/gpu/drm/i915/gt/intel_engine_cs.c b/drivers/gpu/drm/i915/gt/intel_engine_cs.c index 352254e001b4..74aa90587061 100644 --- a/drivers/gpu/drm/i915/gt/intel_engine_cs.c +++ b/drivers/gpu/drm/i915/gt/intel_engine_cs.c @@ -1718,8 +1718,8 @@ static void print_request_ring(struct drm_printer *m, struct i915_request *rq) drm_printf(m, "[head %04x, postfix %04x, tail %04x, batch 0x%08x_%08x]:\n", rq->head, rq->postfix, rq->tail, - vsnap ? upper_32_bits(vsnap->gtt_offset) : ~0u, - vsnap ? lower_32_bits(vsnap->gtt_offset) : ~0u); + vsnap ? upper_32_bits(vsnap->vma_resource->start) : ~0u, + vsnap ? lower_32_bits(vsnap->vma_resource->start) : ~0u); size = rq->tail - rq->head; if (rq->tail < rq->head) -- cgit From 60dc43d1190db1bf80c696ab4561ed53f8f42f33 Mon Sep 17 00:00:00 2001 From: Thomas Hellström Date: Mon, 10 Jan 2022 18:22:19 +0100 Subject: drm/i915: Use struct vma_resource instead of struct vma_snapshot MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is always a struct vma_resource guaranteed to be alive when we access a corresponding struct vma_snapshot. So ditch the latter and instead of allocating vma_snapshots, reference the already existning vma_resource. This requires a couple of extra members in struct vma_resource but that's a small price to pay for the simplification. v2: - Fix a missing include and declaration (kernel test robot ) Signed-off-by: Thomas Hellström Reviewed-by: Matthew Auld Link: https://patchwork.freedesktop.org/patch/msgid/20220110172219.107131-7-thomas.hellstrom@linux.intel.com --- drivers/gpu/drm/i915/gt/intel_engine_cs.c | 9 +++------ 1 file changed, 3 insertions(+), 6 deletions(-) (limited to 'drivers/gpu/drm/i915/gt/intel_engine_cs.c') diff --git a/drivers/gpu/drm/i915/gt/intel_engine_cs.c b/drivers/gpu/drm/i915/gt/intel_engine_cs.c index 74aa90587061..d1daa4cc2895 100644 --- a/drivers/gpu/drm/i915/gt/intel_engine_cs.c +++ b/drivers/gpu/drm/i915/gt/intel_engine_cs.c @@ -1708,18 +1708,15 @@ static void intel_engine_print_registers(struct intel_engine_cs *engine, static void print_request_ring(struct drm_printer *m, struct i915_request *rq) { - struct i915_vma_snapshot *vsnap = &rq->batch_snapshot; + struct i915_vma_resource *vma_res = rq->batch_res; void *ring; int size; - if (!i915_vma_snapshot_present(vsnap)) - vsnap = NULL; - drm_printf(m, "[head %04x, postfix %04x, tail %04x, batch 0x%08x_%08x]:\n", rq->head, rq->postfix, rq->tail, - vsnap ? upper_32_bits(vsnap->vma_resource->start) : ~0u, - vsnap ? lower_32_bits(vsnap->vma_resource->start) : ~0u); + vma_res ? upper_32_bits(vma_res->start) : ~0u, + vma_res ? lower_32_bits(vma_res->start) : ~0u); size = rq->tail - rq->head; if (rq->tail < rq->head) -- cgit
