Comment 15 Tvrtko Ursulin 2016-03-04 15:12:21 UTC

flink-and-close will keep failing until some serious i915 rework happens.

flink-and-exit was temporarily broken and should be fine after https://patchwork.freedesktop.org/patch/75869/ gets merged to IGT.

Comment 16 Chris Wilson 2016-06-15 15:48:53 UTC

It's still a kernel bug.

commit b1f788c6acb2f34622dd5f4c3d5210c6e3945e78

Date:   Thu Aug 4 07:52:45 2016 +0100

    drm/i915: Release vma when the handle is closed
    
    In order to prevent a leak of the vma on shared objects, we need to
    hook into the object_close callback to destroy the vma on the object for
    this file. However, if we destroyed that vma immediately we may cause
    unexpected application stalls as we try to unbind a busy vma - hence we
    defer the unbind to when we retire the vma.
    
    v2: Keep vma allocated until closed. This is useful for a later
    optimisation, but it is required now in order to handle potential
    recursion of i915_vma_unbind() by retiring itself.
    v3: Comments are important.

    We have to flush any queued operations before making an assertion such
    as the VMA being removed from the ppgtt.

We use it to load the GuC. At the moment it is not loaded by default:

https://cgit.freedesktop.org/drm-intel/tree/drivers/gpu/drm/i915/i915_params.c 

struct i915_params i915 __read_mostly = {
        …
	.enable_guc_loading = 0,
	.enable_guc_submission = 0,
        …
};

module_param_named_unsafe(enable_guc_loading, i915.enable_guc_loading, int, 0400);
MODULE_PARM_DESC(enable_guc_loading,
		"Enable GuC firmware loading "
		"(-1=auto, 0=never [default], 1=if available, 2=required)");

module_param_named_unsafe(enable_guc_submission, i915.enable_guc_submission, int, 0400);
