Context switch (and execlist submission) should happen only when other contexts are not active, otherwise pre-emption occurs. To assure this, we place context switch requests in a queue and those request are later consumed when the right context switch interrupt is received (still TODO). v2: Use a spinlock, do not remove the requests on unqueue (wait for context switch completion). Signed-off-by: Thomas Daniel <thomas.daniel@intel.com> v3: Several rebases and code changes. Use unique ID. v4: - Move the queue/lock init to the late ring initialization. - Damien's kmalloc review comments: check return, use sizeof(*req), do not cast. v5: - Do not reuse drm_i915_gem_request. Instead, create our own. - New namespace.
