2019-06-19drm/i915: Make the semaphore saturation mask globalChris Wilson
The idea behind keeping the saturation mask local to a context backfired spectacularly. The premise with the local mask was that we would be more proactive in attempting to use semaphores after each time the context idled, and that all new contexts would attempt to use semaphores ignoring the current state of the system. This turns out to be horribly optimistic. If the system state is still oversaturated and the existing workloads have all stopped using semaphores, the new workloads would attempt to use semaphores and be deprioritised behind real work. The new contexts would not switch off using semaphores until their initial batch of low priority work had completed. Given sufficient backload load of equal user priority, this would completely starve the new work of any GPU time. To compensate, remove the local tracking in favour of keeping it as global state on the engine -- once the system is saturated and semaphores are disabled, everyone stops attempting to use semaphores until the system is idle again. One of the reason for preferring local context tracking was that it worked with virtual engines, so for switching to global state we could either do a complete check of all the virtual siblings or simply disable semaphores for those requests. This takes the simpler approach of disabling semaphores on virtual engines. The downside is that the decision that the engine is saturated is a local measure -- we are only checking whether or not this context was scheduled in a timely fashion, it may be legitimately delayed due to user priorities. We still have the same dilemma though, that we do not want to employ the semaphore poll unless it will be used. v2: Explain why we need to assume the worst wrt virtual engines.

Writeback split is also for workaround the size limitation of d71 scaler. Like layer_split, writeback downscaling also can use two scalers to handle the scaling half-by-half.

The drm_atomic_normalize_zpos allows to configure same zpos for different planes, but komeda doesn't support such configuration. 2. For further slave pipline case, Komeda need to calculate the max_slave_zorder, we will merge such calculation into komed_crtc_normalize_zpos to save a separated plane_state loop. 3. For feature none-scaling layer_split, which a plane_state will be assigned to two individual layers(left/right), which requires two normalize_zpos for this plane, plane_st->normalize_zpos will be used by left layer, normalize_zpos + 1 for right_layer.

The drm subsystem also uses the video= kernel parameter, and in the documentation refers to the fbdev documentation for that parameter. However, that documentation also says that instead of giving the mode using its resolution we can also give a name. However, DRM doesn't handle that case at the moment. Even though in most case it shouldn't make any difference, it might be useful for analog modes, where different standards might have the same resolution, but still have a few different parameters that are not encoded in the modes (NTSC vs NTSC-J vs PAL-M for example).

2019-06-19drm/modes: Rewrite the command line parserMaxime Ripard
Rewrite the command line parser in order to get away from the state machine parsing the video mode lines. Hopefully, this will allow to extend it more easily to support named modes and / or properties set directly on the command line.

2019-06-19drm/client: Change drm_client_panel_rotation nameMaxime Ripard
The drm_client_panel_rotation function has been used so far to set the default rotation based on the panel orientation. However, we can have more sources of information to make that decision, starting with the command line that we will introduce later in this series. Change the name to remove the panel mention.

2019-06-19drm/client: Restrict the rotation check to the rotation itselfMaxime Ripard
The drm_client_rotation has a check on the rotation value, but the reflections are also stored in the same variable, and the check doesn't take this into account. Therefore, even though we might have a valid rotation, if we're also using a reflection parameter, the test will fail for no particular reason.

2019-06-19drm/client: Restrict the plane_state scopeMaxime Ripard
The drm_client_modeset_commit_atomic function uses two times the plane_state variable in inner blocks of code, but the variable has a scope global to this function. This will lead to inadvertent devs to reuse the variable in the second block with the value left by the first, without any warning from the compiler since value would have been initialized. Fix this by moving the variable declaration to the proper scope.
