From f2ef6eb1453a95ce8ab388493793c54a6bedc405 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Mon, 4 Jun 2012 14:42:53 -0700 Subject: [PATCH] drm/i915: switch to default context on idle To keep things as sane as possible, switch to the default context before idling. This should help free context objects, as well as put things in a more well defined state before suspending. v2: remove seqno from context switch call (daniel) return error on failed context switch instead of WARN+continue (daniel) v3: move idling to i915_gpu idle (from i915_gem_idle) (Chris) Signed-off-by: Ben Widawsky --- drivers/gpu/drm/i915/i915_gem.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c index c06f50d44a23..3596f3415624 100644 --- a/drivers/gpu/drm/i915/i915_gem.c +++ b/drivers/gpu/drm/i915/i915_gem.c @@ -2332,6 +2332,10 @@ int i915_gpu_idle(struct drm_device *dev) /* Is the device fubar? */ if (WARN_ON(!list_empty(&ring->gpu_write_list))) return -EBUSY; + + ret = i915_switch_context(ring, NULL, DEFAULT_CONTEXT_ID); + if (ret) + return ret; } return 0; -- GitLab
