Since we use a worker to enable FBC on the CRTC, it is possible for the CRTC to be switched off before we run. In this case, the CRTC will not allow us to wait upon a vblank, so remove the DRM_ERROR as this is very much expected.

Oneshot disabling of IPS when CRC capturing is started is insufficient. IPS may get re-enabled by any plane update, and hence tests that keep CRC capturing on across plane updates will start to see inconsistent results as soon as IPS kicks back in. Add a new knob into the crtc state to make sure IPS stays disabled as long as CRC capturing is enabled. Forcing a modeset is the easiest way to handle this since that's already how we do the panel fitter workaround. It's a little heavy handed just for IPS, but seeing as we might already do the panel fitter workaround I think it's better to follow that. We migth want to optimize both cases later if someone gets too upset by the extra delay from the modeset. v2: Check the right thing when deciding whether to force a modeset v3: Rebase, check HAS_IPS before forcing a modeset, move ips_force_disable check into pipe_config_supports_ips() Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Marta Lofstedt <marta.lofstedt@intel.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=101664Reviewed-by:

By using drm_gem_flink/drm_gem_open on an object using the same fd, it is possible for a client to create multiple handles pointing to the same object (tied to the same contexts and VMA), as exemplified by igt::gem_handle_to_libdrm_bo(). Since this duplication has been possible since forever, we cannot assume that the handle:(fpriv, object) is unique and so must handle the multiple users of a single VMA. v2: Added commentary noise.

To avoid a potential hang condition with TLB invalidation we need to enable masked bit 5 of MMIO 0xE5F0 at boot.

We use WC pages for coherent writes into the ppGTT on !llc architectures. However, to create a WC page requires a stop_machine(), i.e. is very slow. To compensate we currently keep a per-vm cache of recently freed pages, but we still see the slow startup of new contexts. We can amoritize that cost slightly by allocating WC pages in small batches (PAGEVEC_SIZE == 14) and since creating a WC page implies a stop_machine() there is no penalty for keeping that stash global.

If we miss the current vblank because the gpu was busy, that may cause a jitter as the frame rate temporarily drops. We try to limit the impact of this by then boosting the GPU clock to deliver the frame as quickly as possible. Originally done in commit 6ad790c0 ("drm/i915: Boost GPU frequency if we detect outstanding pageflips") but was never forward ported to atomic and finally dropped in commit fd3a4024 ("drm/i915: Rip out legacy page_flip completion/irq handling"). One of the most typical use-cases for this is a mostly idle desktop. Rendering one frame of the desktop's frontbuffer can easily be accomplished by the GPU running at low frequency, but often exceeds the time budget of the desktop compositor. The result is that animations such as opening the menu, doing a fullscreen switch, or even just trying to move a window around are slow and jerky. We need to respond within a frame to give the best impression of a smooth UX, as a compromise we instead respond if that first frame misses its goal. The result should be a near-imperceivable initial delay and a smooth animation even starting from idle. The cost, as ever, is that we spend more power than is strictly necessary as we overestimate the required GPU frequency and then try to ramp down. This of course is reactionary, too little, too late; nevertheless it is surprisingly effective. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=102199Signed-off-by:

Disabling the video DIP when shutting the port down seems like a good idea. Bspec says: "When disabling both the DIP port and DIP transmission, first disable the port and then disable DIP." and "Restriction : GCP is only supported with HDMI when the bits per color is not equal to 8. GCP must be enabled prior to enabling TRANS_DDI_FUNC_CTL for HDMI with bits per color not equal to 8 and disabled after disabling TRANS_DDI_FUNC_CTL" So let's do it in the .post_disable() hook. v2: Remove double "dpms off" caused by rebase fail Signed-off-by:

The corruption in CSB mmio reads we were seeing has been tracked down to incorrectly touching forcewake of all domains, following an engine reset. It is still a mistery why we only catched this in Broxton, since it could happen in any platform.
