Start computing the vlv/chv watermarks the atomic way, from the .compute_pipe_wm() hook. We'll recompute the actual watermarks for only planes that are part of the state, the other planes will keep their watermark from the last time it was computed. And the actual watermark programming will happen from the .initial_watermarks() hook. For now we'll just compute the optimal watermarks, and we'll hook up the intermediate watermarks properly later. The DSPARB registers responsible for the FIFO paritioning are double buffered, so they will be programming from intel_begin_crtc_commit(). v2: s/noninverted/raw/ for consistency with other platforms s/vlv_plane_wm_set/vlv_raw_plane_wm_set/ for clarity Signed-off-by:Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

Let's compute the watermarks first and the FIFO size second. This way we can make sure the FIFO split is the most accommodating to the watermarks. Previously we could have potentially computed a FIFO split that couldn't accommodate the PM2 watermarks simply due to a bad split even if the total FIFO size would have been sufficient. It'll also allow us to avoid recomputing the wms for all planes whenever the FIFO split would change. Thus we don't have to add any extra planes to the state when the FIFO needs to be repartitioned. To help with this we'll keep around copies of the non-inverted watermarks in the crtc state. For now that doesn't help too much, but once we start to do the watermark computation only for the planes that change we'll need the non-inverted values around for the other planes. v2: s/noninverted/raw/ for consistency with other platforms Fix the memset() of the "raw" watermarks Signed-off-by: -

In a lot of place we wish to know which planes on the crtc are actually visible, or how many of them there are. Let's start tracking that in a bitmask in the crtc state. We already track enabled planes (ie. ones with an fb and crtc specified by the user) but that's not quite the same thing as enabled planes may still end up being invisible due to clipping and whatnot.

If we manage to tangle errorpaths and get call to callbacks, it is better to defensively keep them as null until object init is finished so that we get clean null deref on callsite, instead of more cryptic wreckage with partly initialized vm objects. Signed-off-by:

If we setup the vm size early, we can use the newly introduced i915_vm_is_48bit() in majority of callsites wanting to know the vm size.

Chris Wilson authored
During reset_all_global_seqno() on seqno rollover, we have to update the HWS. This causes all in flight requests to be completed, so first we wait. However, we were only waiting for the requests themselves to be completed and clearing out the waiter rbtrees - what I had missed was the extra reference in execlists->port[]. Since commit fe9ae7a3 ("drm/i915/execlists: Detect an out-of-order context switch") we can detect when the request is retired before the context switch interrupt is completed. The impact should be neglible outside of debugging. Testcase: igt/gem_exec_whisper Signed-off-by:

Adding to the tail of the client request list as the only other user is in the throttle ioctl that iterates forwards over the list. It only needs protection against deletion of a request as it reads it, it simply won't see a new request added to the end of the list, or it would be too early and rejected. We can further reduce the number of spinlocks required when throttling by removing stale requests from the client_list as we throttle. Signed-off-by:

Currently ILK-BDW explicitly disable LP1+ watermarks from their .init_clock_gating() hooks. Unfortunately that hook gets called way too late since by that time we've already initialized all the watermark state tracking which then gets out of sync with the hardware state. We may eventually want to consider killing off the explicit LP1+ disable from .init_clock_gating(). In the meantime however, we can avoid the problem by reordering the init sequence such that intel_modeset_init_hw()->intel_init_clock_gating() gets called prior to the hardware state takeover. I suppose prior to the two stage watermark programming we were magically saved by something that forced the watermarks to be reprogrammed fully after .init_clock_gating() got called. But now that no longer happens. Note that the diff might look a bit odd as it kills off one call of intel_update_cdclk(), but that's fine because intel_modeset_init_hw() does the exact same thing. Previously we just did it twice. Actually even this new init sequence is pretty bogus as .init_clock_gating() really should be called before any gem hardware init since it can configure various clock gating workarounds and whatnot that affect the GT side as well. Also intel_modeset_init() really should get split up into better defined init stages. Another "fun" detail is that intel_modeset_gem_init() is where RPS/RC6 gets configured. Why that is done from the display code is beyond me. I've decided to leave all this be for now, and just try to fix the init sequence enough for watermarks to work.

In order to make cursor updates actually safe wrt. watermark programming we have to clear the legacy_cursor_update flag in the atomic state. That will cause the regular atomic update path to do the necessary vblank wait after the plane update if needed, otherwise the vblank wait would be skipped and we'd feed the optimal watermarks to the hardware before the plane update has actually happened. To make the slow vs. fast path determination in intel_legacy_cursor_update() a little simpler we can ignore the actual visibility of the plane (which can only get computed once we've already chosen out path) and instead we simply check whether the fb is being set or cleared by the user. This means a fully clipped but logically visible cursor will be considered visible as far as watermark programming is concerned. We can do that for the cursor since it's a fixed size plane and the clipped size doesn't play a role in the watermark computation. This should fix underruns that can occur when the cursor gets enable/disabled or the size gets changed. Hopefully it's good enough that only pure cursor movement and flips go through unthrottled.

Commit 62b69566 ("drm/i915: Only enable DDI IO power domains after enabling DPLL") changed how the DDI IO power domains get enabled, but neglected the need to enable those domains when enabling a DP connector with MST enabled, leading to Kernel panic - not syncing: Timeout: Not all CPUs entered broadcast exception handler Fixes: 62b69566 ("drm/i915: Only enable DDI IO power domains after enabling DPLL") Cc: Imre Deak <imre.deak@intel.com> Cc: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Cc: David Weinehall <david.weinehall@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: intel-gfx@lists.freedesktop.org Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reported-by:

Reintroduce a lock around tiling vs framebuffer creation to prevent modification of the obj->tiling_and_stride whilst the framebuffer is being created. Rather than use struct_mutex once again, use the per-object lock - this will also be required in future to prevent changing the tiling whilst submitting rendering. Reported-by:

For v3 VBTs in vid-mode the delays are part of the VBT sequences, so we should not also delay ourselves otherwise we get double delays. Signed-off-by:

According to the spec we should call MIPI_SEQ_TEAR_ON and DISPLAY_ON on enable for cmd-mode, just like we already call their counterparts on disable. Note: untested, my panel is a vid-mode panel. Signed-off-by:
