2016-11-25drm/i915: Integrate i915_sw_fence with debugobjectsChris Wilson4-7/+161
Add the tracking required to enable debugobjects for fences to improve error detection in BAT. The debugobject interface lets us track the lifetime and phases of the fences even while being embedded into larger structs, i.e. to check they are not used after they have been released. v2: Don't populate the stubs, debugobjects checks for a NULL pointer and treats it equivalently.

2016-11-25drm/i915: Hold a reference on the request for its fence chainChris Wilson2-7/+32
Currently, we have an active reference for the request until it is retired. Though it cannot be retired before it has been executed by hardware, the request may be completed before we have finished processing the execute fence, i.e. we may continue to process that fence as we free the request.

A modeset on one pipe can update dev_priv->atomic_cdclk_freq without actually touching the hardware, in which case we won't force a modeset on all the pipes, and thus won't lock any of the other pipes either. That means a parallel plane update on another pipe could be looking at a stale dev_priv->atomic_cdcdlk_freq and thus fail to notice when the plane configuration is invalid, or potentially reject a valid update. To overcome this we must protect writes to atomic_cdclk_freq with all the crtc locks, and thus for reads any single crtc lock will be sufficient protection.

When we end up not recomputing the cdclk, we need to populate intel_state->cdclk with the "atomic_cdclk_freq" instead of the current cdclk_freq. When no pipes are active, the actual cdclk_freq may be lower than what the configuration of the planes and pipes would require from the point of view of the software state. This fixes bogus WARNS from skl_max_scale() which is trying to check the plane software state against the cdclk frequency. So any time it got called during DPMS off for instance, we might have tripped the warn if the current mode would have required a higher than minimum cdclk. v2: Drop the dev_cdclk stuff (Maarten) Cc: Maarten Lankhorst <[email protected]> Cc: Mika Kahola <[email protected]> Cc: [email protected] Cc: Daniel J Blueman <[email protected]> Cc: Paul Bolle <[email protected]> Cc: Joseph Yasi <[email protected]> Tested-by: Paul Bolle <[email protected]> Tested-by: Joseph Yasi <[email protected]> (v1) Cc: [email protected] Fixes: 1a617b77658e ("drm/i915: Keep track of the cdclk as if all crtc's were active.")

Tesselation picture vm fault disappeared after vgt-flush introduced. v2:implement vgt-flush for CI & SI. v3:move vgt flush inside of cntx_cntrl v4:count vgt flush in frame_size v5:squash in typo fix Signed-off-by: Monk Liu <[email protected]> Reviewed-by: Alex Deucher <[email protected]> Reviewed-by: Christian König <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
