From: Mika Kuoppala <[email protected]> for proper refcounting to take place as we use i915_add_request() for it.
i915_add_request() also takes the context for the request from ring->last_context so move the null state batch submission after the ring context has been set. v2: we need to check for correct ring now (Ville Syrjälä) v3: no need to expose i915_gem_move_object_to_active (Chris Wilson) v4: cargoculted vma/active/inactive error handling removed (Chris Wilson) Cc: Ville Syrjälä <[email protected]> Cc: Chris Wilson <[email protected]> Cc: Damien Lespiau <[email protected]> Signed-off-by: Mika Kuoppala <[email protected]> Signed-off-by: Daniel Vetter <[email protected]> --- drivers/gpu/drm/i915/i915_gem_context.c | 16 ++++++++-------- drivers/gpu/drm/i915/i915_gem_render_state.c | 8 ++++++-- 2 files changed, 14 insertions(+), 10 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_gem_context.c b/drivers/gpu/drm/i915/i915_gem_context.c index f220c94..6a2d847a 100644 --- a/drivers/gpu/drm/i915/i915_gem_context.c +++ b/drivers/gpu/drm/i915/i915_gem_context.c @@ -700,21 +700,21 @@ static int do_switch(struct intel_ring_buffer *ring, /* obj is kept alive until the next request by its active ref */ i915_gem_object_ggtt_unpin(from->obj); i915_gem_context_unreference(from); - } else { - if (to->is_initialized == false) { - ret = i915_gem_render_state_init(ring); - if (ret) - DRM_ERROR("init render state: %d\n", ret); - } } - to->is_initialized = true; - done: i915_gem_context_reference(to); ring->last_context = to; to->last_ring = ring; + if (ring->id == RCS && !to->is_initialized && from == NULL) { + ret = i915_gem_render_state_init(ring); + if (ret) + DRM_ERROR("init render state: %d\n", ret); + } + + to->is_initialized = true; + return 0; unpin_out: diff --git a/drivers/gpu/drm/i915/i915_gem_render_state.c b/drivers/gpu/drm/i915/i915_gem_render_state.c index 392aa7b..cfbf6fc 100644 --- a/drivers/gpu/drm/i915/i915_gem_render_state.c +++ b/drivers/gpu/drm/i915/i915_gem_render_state.c @@ -164,9 +164,11 @@ int i915_gem_render_state_init(struct intel_ring_buffer *ring) const int gen = INTEL_INFO(ring->dev)->gen; struct i915_render_state *so; const struct intel_renderstate_rodata *rodata; - u32 seqno; int ret; + if (WARN_ON(ring->id != RCS)) + return -ENOENT; + rodata = render_state_get_rodata(ring->dev, gen); if (rodata == NULL) return 0; @@ -186,8 +188,10 @@ int i915_gem_render_state_init(struct intel_ring_buffer *ring) if (ret) goto out; - ret = i915_add_request(ring, &seqno); + i915_vma_move_to_active(i915_gem_obj_to_ggtt(so->obj), ring); + ret = __i915_add_request(ring, NULL, so->obj, NULL); + /* __i915_add_request moves object to inactive if it fails */ out: render_state_free(so); return ret; -- 1.7.9.5 _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
