The visible member used to be in intel_plane_state->visible, but has been moved to drm_plane_state->visible. In the conversion some casts were left in that are now useless. to_intel_plane_state(x)->base.visible is the same as x->visible, so use the latter to clear up the code a little.

The core provides now an ABI to userspace for generation of frame CRCs, so implement the ->set_crc_source() callback and reuse as much code as possible with the previous ABI implementation. When handling the pageflip interrupt, we skip 1 or 2 frames depending on the HW because they contain wrong values. For the legacy ABI for generating frame CRCs, this was done in userspace but now that we have a generic ABI it's better if it's not exposed by the kernel. v2: - Leave the legacy implementation in place as the ABI implementation in the core is incompatible with it. v3: - Use the "cooked" vblank counter so we have a whole 32 bits. - Make sure we don't mess with the state of the legacy CRC capture ABI implementation. v4: - Keep use of get_vblank_counter as in the legacy code, will be changed in a followup commit. v5: - Skip first frame or two as it's known that they contain wrong data. - A few fixes suggested by Emil Velikov. v6: - Rework programming of the HW registers to preserve previous behavior. v7: - Address whitespace issue. - Added a comment on why in the implementation of the new ABI we skip the 1st or 2nd frames. v9: - Add stub for intel_crtc_set_crc_source. v12: - Rebased. - Remove stub for intel_crtc_set_crc_source and instead set the callback to NULL (Jani Nikula). v15: - Rebased.

In future patches, we require greater flexibility in describing the number of scalers available on each CRTC. To ease that transition we move the current assignment to intel_device_info. Scaler structure initialisation is done if scaler is available on the CRTC.

commit 848496e5 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Wed Jul 13 16:32:03 2016 +0300 drm/i915: Wait up to 3ms for the pcu to ack the cdclk change request on SKL increased the timeout to match the spec, but we still see a timeout on at least one SKL. A CDCLK change request following the failed one will succeed nevertheless. I could reproduce this problem easily by running kms_pipe_crc_basic in a loop. In all failure cases _wait_for() was pre-empted for >3ms and so in the worst case - when the pre-emption happened right after calculating timeout__ in _wait_for() - we called skl_cdclk_wait_for_pcu_ready() only once which failed and so _wait_for() timed out. As opposed to this the spec says to keep retrying the request for at most a 3ms period. To fix this send the first request explicitly to guarantee that there is 3ms between the first and last request. Though this matches the spec, I noticed that in rare cases this can still time out if we sent only a few requests (in the worst case 2) _and_ PCODE is busy for some reason even after a previous request and a 3ms delay. To work around this retry the polling with pre-emption disabled to maximize the number of requests. Also increase the timeout to 10ms to account for interrupts that could reduce the number of requests. With this change I couldn't trigger the problem. v2: - Use 1ms poll period instead of 10us. (Chris) v3: - Poll with pre-emption disabled to increase the number of request attempts. (Ville, Chris) - Factor out a helper to poll, it's also needed by the next patch. v4: - Pass reply_mask, reply to skl_pcode_request(), instead of assuming the reply is generic. (Ville) v5: - List the request specific timeout values as code comment. (Ville) v6: - Try the poll first with preemption enabled. - Add code comment about first request being queued by PCODE. (Art) - Add timeout_base_ms argument. (Ville) v7: - Clarify code comment about first queued request.

This will allow cursor movement to be smooth, but changing cursor size or showing/hiding cursor will still fall back so watermarks can be updated. Only moving and changing fb is allowed. Changes since v1: - Set page flip to always_unused for trybot. - Copy fence correctly, ignore plane_state->state, should be NULL. - Check crtc_state for !active and modeset, go to slowpath if the case.

The requests conversion introduced a nasty bug where we could generate a new request in the middle of constructing a request if we needed to idle the system in order to evict space for a context. The request to idle would be executed (and waited upon) before the current one, creating a minor havoc in the seqno accounting, as we will consider the current request to already be completed (prior to deferred seqno assignment) but ring->last_retired_head would have been updated and still could allow us to overwrite the current request before execution. We also employed two different mechanisms to track the active context until it was switched out. The legacy method allowed for waiting upon an active context (it could forcibly evict any vma, including context's), but the execlists method took a step backwards by pinning the vma for the entire active lifespan of the context (the only way to evict was to idle the entire GPU, not individual contexts). However, to circumvent the tricky issue of locking (i.e. we cannot take struct_mutex at the time of i915_gem_request_submit(), where we would want to move the previous context onto the active tracker and unpin it), we take the execlists approach and keep the contexts pinned until retirement. The benefit of the execlists approach, more important for execlists than legacy, was the reduction in work in pinning the context for each request - as the context was kept pinned until idle, it could short circuit the pinning for all active contexts. We introduce new engine vfuncs to pin and unpin the context respectively. The context is pinned at the start of the request, and only unpinned when the following request is retired (this ensures that the context is idle and coherent in main memory before we unpin it). We move the engine->last_context tracking into the retirement itself (rather than during request submission) in order to allow the submission to be reordered or unwound without undue difficultly. And finally an ulterior motive for unifying context handling was to prepare for mock requests. v2: Rename to last_retired_context, split out legacy_context tracking for MI_SET_CONTEXT.

Rather than compare the format u32s of two format infos, we can direclty compare the format info pointers themselves. Noramlly all the ->format pointers all point to somwehere in the big array, so this is a valid way to test for equality. Also drivers may want to point ->format at a private format info struct instead (eg. for special compressed formats with extra planes), so just comparing the pixel format values wouldn't necessaritly even work.

commit 848496e5 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Wed Jul 13 16:32:03 2016 +0300 drm/i915: Wait up to 3ms for the pcu to ack the cdclk change request on SKL increased the timeout to match the spec, but we still see a timeout on at least one SKL. A CDCLK change request following the failed one will succeed nevertheless. I could reproduce this problem easily by running kms_pipe_crc_basic in a loop. In all failure cases _wait_for() was pre-empted for >3ms and so in the worst case - when the pre-emption happened right after calculating timeout__ in _wait_for() - we called skl_cdclk_wait_for_pcu_ready() only once which failed and so _wait_for() timed out. As opposed to this the spec says to keep retrying the request for at most a 3ms period. To fix this send the first request explicitly to guarantee that there is 3ms between the first and last request. Though this matches the spec, I noticed that in rare cases this can still time out if we sent only a few requests (in the worst case 2) _and_ PCODE is busy for some reason even after a previous request and a 3ms delay. To work around this retry the polling with pre-emption disabled to maximize the number of requests. Also increase the timeout to 10ms to account for interrupts that could reduce the number of requests. With this change I couldn't trigger the problem. v2: - Use 1ms poll period instead of 10us. (Chris) v3: - Poll with pre-emption disabled to increase the number of request attempts. (Ville, Chris) - Factor out a helper to poll, it's also needed by the next patch. v4: - Pass reply_mask, reply to skl_pcode_request(), instead of assuming the reply is generic. (Ville) v5: - List the request specific timeout values as code comment. (Ville) v6: - Try the poll first with preemption enabled. - Add code comment about first request being queued by PCODE. (Art) - Add timeout_base_ms argument. (Ville) v7: - Clarify code comment about first queued request.

Before we attempt to turn any planes on or off we must first exit csxr. That's due to cxsr effectively making the plane enable bits read-only. Currently we achieve that with a vblank wait right after toggling the cxsr enable bit. We do the vblank wait even if cxsr was already off, which seems wasteful, so let's try to only do it when absolutely necessary. We could start tracking the cxsr state fully somewhere, but for now it seems easiest to just have intel_set_memory_cxsr() return the previous cxsr state.

David found another issue with priority bumping from mmioflips, where we are accessing the requests concurrently to them being retired and freed. Whilst we are skipping the dependency if has been submitted, that is not sufficient to stop the dependency from disappearing if another thread retires that request. To prevent we can either employ the struct_mutex (or a request mutex in the future) to serialise retiring before it is freed. Alternatively, we need to keep the dependencies alive using RCU whilst they are being accessed via the DFS.

Looks like we're only initializing dev_priv->atomic_cdclk_freq at resume and commit times, not at init time. Let's do that as well. We're now hitting the 'WARN_ON(intel_state->cdclk == 0)' in hsw_compute_linetime_wm() on account of populating intel_state->cdclk from dev_priv->atomic_cdclk_freq. Previously we were mispopulating intel_state->cdclk with dev_priv->cdclk_freq which always had a proper value at init time and hence the WARN_ON() didn't trigger.

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 <maarten.lankhorst@linux.intel.com> Cc: Mika Kahola <mika.kahola@intel.com> Cc: bruno.pagani@ens-lyon.org Cc: Daniel J Blueman <daniel.blueman@gmail.com> Cc: Paul Bolle <pebolle@tiscali.nl> Cc: Joseph Yasi <joe.yasi@gmail.com> Tested-by: NPaul Bolle <pebolle@tiscali.nl> Tested-by: Joseph Yasi <joe.yasi@gmail.com> (v1) Cc: <stable@vger.kernel.org> # v4.6+ Fixes: 1a617b77 ("drm/i915: Keep track of the cdclk as if all crtc's were active.")
