For LSPCON initialization during system resume we need AUX functionality, but we call the corresponding encoder reset hook with all interrupts disabled. Without interrupts we'll do a poll-wait for AUX transfer completions, which adds a significant delay if the transfers timeout/need to be retried for some reason. Fix this by enabling interrupts before calling the reset hooks. Note that while this will enable AUX interrupts it will keep HPD interrupts disabled, in a similar way to the init time output setup code. This issue existed since LSPCON support was added. v2: - Rebased on drm-tip. Cc: Shashank Sharma <shashank.sharma@intel.com> Signed-off-by:

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.

Something I missed before sending off the partial series was that the non-scheduler guc reset path was broken (in the full series, this is pushed to the execlists reset handler). The issue is that after a reset, we have to refill the GuC workqueues, which we do by resubmitting the requests. However, if we already have submitted them, the fences within them have already been used and triggering them again is an error. Instead, just repopulate the guc workqueue.

In order to avoid some complexity in trying to reconstruct the workqueues across reset, remember them instead. The issue comes when we have to handle a reset between request allocation and submission, the request has reserved space in the wq, but is not in any list so we fail to restore the reserved space. By keeping the execbuf client intact across the reset, we also keep the reservations. Signed-off-by:

i915_guc_info() (part of debugfs output) tries to avoid holding struct_mutex for a long period by copying onto the stack. This causes a warning that the stack frame is massive, so stop doing that. We can even forgo holding the struct_mutex here as that doesn't serialise the values being read (and the lists used exist for the device lifetime). v2: Skip printing anything if guc->execbuf_client is disabled (avoids potential NULL dereference).

This patch adds support for DP MST audio in i915. Enable audio codec when DP MST is enabled if has_audio flag is set. Disable audio codec when DP MST is disabled if has_audio flag is set. Another separated patches to support DP MST audio will be implemented in audio driver. This patch is ported from commit 3708d5e0 ("drm/i915: start adding dp mst audio") And because commit 3708d5e0 ("drm/i915: start adding dp mst audio") breaks MST multi-monitor setups on some platforms, the orignal patch is reverted by commit be754b10 ("Revert "drm/i915: start adding dp mst audio"") As the multi-monitor setups issue is fixed, let's port the patch and enable the dp mst audio.

99% of the time we access i915_address_space->dev we want the i915 device and not the drm device, so let's store the drm_i915_private backpointer instead. The only real complication here are the inlines in i915_vma.h where drm_i915_private is not yet defined and so we have to choose an alternate path for our asserts. Signed-off-by:

a PT page will be released if it doesn't contain any meaningful mappings during PPGTT page table shrinking. The PT entry in the upper level will be set to a scratch entry. Normally this works nicely, but in virtualization world, the PPGTT page table is tracked by hypervisor. Releasing the PT page before modifying the upper level PT entry would cause extra efforts. As the tracked page has been returned to OS before losing track from hypervisor, it could be written in any pattern. Hypervisor has to recognize if a page is still being used as a PT page by validating these writing patterns. It's complicated. Better let the guest modify the PT entry in upper level PT first, then release the PT page. Reviewed-by:

Chris Wilson authored
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.

send_mutex is used to serialise communication with GuC via intel_guc_send(). Since functions that utilize it are no longer limited to submission, initialization should be handled as a part of general setup. v2: move initialization to *_early() Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michal Winiarski <michal.winiarski@intel.com> Signed-off-by:

guc_send(), guc_recv() and related functions were introduced in the i915_guc_submission.c and their scope was limited only to that file. Those are not submission specific though. This patch moves moves them to intel_uc.c with intel_ prefix added. v2: rename intel_guc_log_* functions and clean up intel_guc_send usages Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michal Winiarski <michal.winiarski@intel.com> Signed-off-by:

To facilitate code reorganization we are renaming everything that contains guc2host or host2guc. host2guc_action() and host2guc_action_response() become guc_send() and guc_recv() respectively. Other host2guc_*() functions become simply guc_*(). Other entities are renamed basing on context they appear in: - HOST2GUC_ACTIONS_& become INTEL_GUC_ACTION_* - HOST2GUC_{INTERRUPT,TRIGGER} become GUC_SEND_{INTERRUPT,TRIGGER} - GUC2HOST_STATUS_* become INTEL_GUC_STATUS_* - GUC2HOST_MSG_* become INTEL_GUC_RECV_MSG_* - action_lock becomes send_mutex v2: drop unnecessary backslashes and use BIT() instead of '<<' v3: shortened enum names and INTEL_GUC_STATUS_* Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michal Winiarski <michal.winiarski@intel.com> Signed-off-by: -

GuC is not the only one micro controller we have. There are also HuC and DMC. Making the file more general will help with code organization. Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michal Winiarski <michal.winiarski@intel.com> Signed-off-by:

The check in __intel_uncore_early_sanitize() to disable decoupled mmio would disable it for every platform that is not broxton. While that's not a problem now since only broxton supports that, simply setting .has_decoupled_mmio in a new platform's device info wouldn't suffice. So avoid future confusion and change the workaround to only change the value of has_decoupled_mmio for broxton. v2: git add compile fix.
