From e28e404c3e93378c6ef3e2e6c9c5b1ab51e54bc4 Mon Sep 17 00:00:00 2001 From: Dave Gordon Date: Tue, 19 Jan 2016 19:02:55 +0000 Subject: [PATCH] drm/i915: tidy up a few leftovers There are a few bits of code which the transformations implemented by the previous patch reveal to be suboptimal, once the notion of a per- ring default context has gone away. So this tidies up the leftovers. It could have been squashed into the previous patch, but that would have made that patch less clearly a simple transformation. In particular, any change which alters the code block structure or indentation has been deferred into this separate patch, because such things tend to make diffs more difficult to read. v4: Rebased Signed-off-by: Dave Gordon Reviewed-by: Nick Hoath Link: http://patchwork.freedesktop.org/patch/msgid/1453230175-19330-4-git-send-email-david.s.gordon@intel.com Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_debugfs.c | 15 ++++-------- drivers/gpu/drm/i915/i915_gem.c | 6 ++--- drivers/gpu/drm/i915/intel_lrc.c | 38 +++++++++++++---------------- 3 files changed, 24 insertions(+), 35 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_debugfs.c b/drivers/gpu/drm/i915/i915_debugfs.c index 37c2c5009d9a..c5db23511184 100644 --- a/drivers/gpu/drm/i915/i915_debugfs.c +++ b/drivers/gpu/drm/i915/i915_debugfs.c @@ -1960,11 +1960,8 @@ static int i915_context_status(struct seq_file *m, void *unused) seq_puts(m, "HW context "); describe_ctx(m, ctx); - for_each_ring(ring, dev_priv, i) { - if (dev_priv->kernel_context == ctx) - seq_printf(m, "(default context %s) ", - ring->name); - } + if (ctx == dev_priv->kernel_context) + seq_printf(m, "(kernel context) "); if (i915.enable_execlists) { seq_putc(m, '\n'); @@ -2056,12 +2053,10 @@ static int i915_dump_lrc(struct seq_file *m, void *unused) if (ret) return ret; - list_for_each_entry(ctx, &dev_priv->context_list, link) { - for_each_ring(ring, dev_priv, i) { - if (dev_priv->kernel_context != ctx) + list_for_each_entry(ctx, &dev_priv->context_list, link) + if (ctx != dev_priv->kernel_context) + for_each_ring(ring, dev_priv, i) i915_dump_lrc_obj(m, ctx, ring); - } - } mutex_unlock(&dev->struct_mutex); diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c index 06abe1bf5afc..6a3e4ee7f7e2 100644 --- a/drivers/gpu/drm/i915/i915_gem.c +++ b/drivers/gpu/drm/i915/i915_gem.c @@ -2679,10 +2679,8 @@ void i915_gem_request_free(struct kref *req_ref) i915_gem_request_remove_from_client(req); if (ctx) { - if (i915.enable_execlists) { - if (ctx != req->i915->kernel_context) - intel_lr_context_unpin(req); - } + if (i915.enable_execlists && ctx != req->i915->kernel_context) + intel_lr_context_unpin(req); i915_gem_context_unreference(ctx); } diff --git a/drivers/gpu/drm/i915/intel_lrc.c b/drivers/gpu/drm/i915/intel_lrc.c index 2c6da4013b1a..134379dc4dd9 100644 --- a/drivers/gpu/drm/i915/intel_lrc.c +++ b/drivers/gpu/drm/i915/intel_lrc.c @@ -686,16 +686,10 @@ static int execlists_move_to_gpu(struct drm_i915_gem_request *req, int intel_logical_ring_alloc_request_extras(struct drm_i915_gem_request *request) { - int ret; + int ret = 0; request->ringbuf = request->ctx->engine[request->ring->id].ringbuf; - if (request->ctx != request->i915->kernel_context) { - ret = intel_lr_context_pin(request); - if (ret) - return ret; - } - if (i915.enable_guc_submission) { /* * Check that the GuC has space for the request before @@ -709,7 +703,10 @@ int intel_logical_ring_alloc_request_extras(struct drm_i915_gem_request *request return ret; } - return 0; + if (request->ctx != request->i915->kernel_context) + ret = intel_lr_context_pin(request); + + return ret; } static int logical_ring_wait_for_space(struct drm_i915_gem_request *req, @@ -2391,22 +2388,21 @@ void intel_lr_context_free(struct intel_context *ctx) { int i; - for (i = 0; i < I915_NUM_RINGS; i++) { + for (i = I915_NUM_RINGS; --i >= 0; ) { + struct intel_ringbuffer *ringbuf = ctx->engine[i].ringbuf; struct drm_i915_gem_object *ctx_obj = ctx->engine[i].state; - if (ctx_obj) { - struct intel_ringbuffer *ringbuf = - ctx->engine[i].ringbuf; - struct intel_engine_cs *ring = ringbuf->ring; + if (!ctx_obj) + continue; - if (ctx == ctx->i915->kernel_context) { - intel_unpin_ringbuffer_obj(ringbuf); - i915_gem_object_ggtt_unpin(ctx_obj); - } - WARN_ON(ctx->engine[ring->id].pin_count); - intel_ringbuffer_free(ringbuf); - drm_gem_object_unreference(&ctx_obj->base); + if (ctx == ctx->i915->kernel_context) { + intel_unpin_ringbuffer_obj(ringbuf); + i915_gem_object_ggtt_unpin(ctx_obj); } + + WARN_ON(ctx->engine[i].pin_count); + intel_ringbuffer_free(ringbuf); + drm_gem_object_unreference(&ctx_obj->base); } } @@ -2481,7 +2477,7 @@ static void lrc_setup_hardware_status_page(struct intel_engine_cs *ring, */ int intel_lr_context_deferred_alloc(struct intel_context *ctx, - struct intel_engine_cs *ring) + struct intel_engine_cs *ring) { struct drm_device *dev = ring->dev; struct drm_i915_gem_object *ctx_obj; -- 2.20.1
