When PSR2 is active aka after the number of frames programmed in PSR2_CTL 'Frames Before SU Entry' hardware stops to generate CRC interrupts causing IGT tests to fail due timeout. This same behavior don't happen with PSR1, as soon as pipe CRC is enabled it blocks PSR1 activation so CRC calculation continues to happens normaly. This patch also set mode_changed as true when PSR is available to force atomic check functions to compute new PSR state, otherwise PSR2 would not be disabled. v4: Only setting mode_changed if has_psr is set(Dhinakaran) v3: Reusing intel_crtc_crc_prepare() and crc_enabled, only setting mode_changed if it can do PSR. v2: Changed commit description to describe that PSR2 inhibit CRC calculations.

In any commit, intel_modeset_pipe_config() will initialilly clear and then recalculate most of the pipe states but it leave intel specific color features states in reset state. If after intel_pipe_config_compare() is detected that a fastset is possible it will mark update_pipe as true and unsed mode_changed, causing the color features state to be kept in reset state and then latter being committed to hardware disabling the color features. This issue can be reproduced by any code patch that duplicates the actual(with color features already enabled) state and only mark mode_changed as true.

Introduce a mutex to start locking the HW contexts independently of struct_mutex, with a view to reducing the coarse struct_mutex. The intel_context.pin_mutex is used to guard the transition to and from being pinned on the gpu, and so is required before starting to build any request. The intel_context will then remain pinned until the request completes, but the mutex can be released immediately unpin completion of pinning the context. A slight variant of the above is used by per-context sseu that wants to inspect the pinned status of the context, and requires that it remains stable (either !pinned or pinned) across its operation. By using the pin_mutex to serialise operations while pin_count==0, we can take that pin_mutex for stabilise the boolean pin status. v2: for Tvrtko! * Improved commit message. * Dropped _gpu suffix from gen8_modify_rpcs_gpu. v3: Repair the locking for sseu selftests Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: NTvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190308132522.21573-7-chris@chris-wilson.co.uk

PPS locking is a thing on pre-DDI, up to and including CPT and PPT. The PPS divisor register exists up to gen 9 BC, replaced by a field in the control register starting from gen 9 LP, i.e. BXT, GLK, and CNP on. Commit b0a08bec ("drm/i915/bxt: eDP Panel Power sequencing") stopped using the divisor register, but inadvertently conflated the PPS unlock in the change. No longer doing the unlocking was the right thing to do, however we should've stopped already at LPT (or DDI platforms). Deconflate the two. Arguably this could be moved away from here altogether, but this is the minimally intrusive change for now.

When the system idles, we switch to the kernel context as a defensive measure (no users are harmed if the kernel context is lost). Currently, we issue a switch to kernel context and then come back later to see if the kernel context is still current and the system is idle. However, if we are no longer privy to the runqueue ordering, then we have to relax our assumptions about the logical state of the GPU and the only way to ensure that the kernel context is currently loaded is by issuing a request to run after all others, and wait for it to complete all while preventing anyone else from issuing their own requests. v2: Pull wedging into switch_to_kernel_context_sync() but only after waiting (though only for the same short delay) for the active context to finish.

Pretend that we have only 1 DBuf slice and that 1 slice is always enabled, until we have a proper way for on-demand toggling of the second slice. Currently we'll try to incorrectly enable DBuf even when all pipes are disabled and we are already runtime suspended (as the computed number of DBuf slices will be 1 in that case). This also means we'll leave the second slice enabled redundantly (except when suspended), but that's an acceptable tradeoff until we have a proper solution.

Now with the watermarks fixes merged, Icelake is stable enough to have the alpha support protection flag removed. We have a few ICL machines in our CI and it is mostly green with failures in tests that will not impact future linux installations. Also there is no warnings, errors, flickering or any visual defects while doing ordinary tasks like browsing and editing documents in a dual monitor setup. As a reminder i915.alpha_support was created to protect future linux installation's iso images that might contain a kernel from the enabling time of the new platform. Without this protection most of linux installation was recommending nomodeset option during installation that was getting stick there after installation. Specifically, alpha support says nothing about the development state of the hardware, and everything about the state of the driver in a kernel release. This is semantically no different from the old preliminary_hw_support flag, but the old one was all too often interpreted as (preliminary hw) support instead of the intended (preliminary) hw support, and it was misleading for everyone. Hence the rename.

That is we will not be able to rely on hangcheck to terminate a blocking kernel and instead must manually do so ourselves. The advantage is that we can apply more pressure! As we now perform a GPU reset to clean up any residual kernels, we leave the GPU in an unknown state and in particular can not talk to the GuC before we reinitialise it following resume.
