While loading the DMC firmware we were double checking the headers made sense, but in no place we checked that we were actually reading memory we were supposed to. This could be wrong in case the firmware file is truncated or malformed.

On i915_gem_load_power_context() we do care whether or not we succeed in completing the switch back to the kernel context (via idling the engines). Currently, we detect if an error occurs while we wait, but we do not report one if it occurred beforehand (and the status of the switch is undefined). Check the current terminally wedged status on entering the wait, and report it after flushing the requests, as if it had occurred during our own wait.

The intent was to skip unused HW contexts by checking ce->state. However, this only works for execlists where the ppGTT pointers is stored inside the HW context. For gen7, the ppGTT is alongside the logical state and must be updated on all active engines but, crucially, only on active engines. As we need different checks, and to keep context_barrier_task() agnostic, pass in the predicate.

Prior to this commit we fail to init the DSI panel on the GPD MicroPC: https://www.indiegogo.com/projects/gpd-micropc-6-inch-handheld-industry-laptop#/ The problem is intel_dsi_vbt_init() failing with the following error: *ERROR* Burst mode freq is less than computed The pclk in the VBT panel modeline is 70000, together with 24 bpp and 4 lines this results in a bitrate value of 70000 * 24 / 4 = 420000. But the target_burst_mode_freq in the VBT is 418000. This commit works around this problem by adding an intel_fuzzy_clock_check when target_burst_mode_freq < bitrate and setting target_burst_mode_freq to bitrate when that checks succeeds, fixing the panel not working.

Instead of relying on the caller holding struct_mutex across the allocation, push the allocation under a tree of spinlocks stored inside the page tables. Not only should this allow us to avoid struct_mutex here, but it will allow multiple users to lock independent ranges for concurrent allocations, and operate independently. This is vital for pushing the GTT manipulation into a background thread where dependency on struct_mutex is verboten, and for allowing other callers to avoid struct_mutex altogether. v2: Restore lost GEM_BUG_ON for removing too many PTE from gen6_ppgtt_clear_range.

As the fence registers are not part of the engine powerwells, we do not need to fiddle with forcewake in order to update a fence. Avoid using the heavyweight debug checking normal mmio writes as the checking dominates the selftest runtime and is superfluous!

Stop dumping plane->state for planes. That is the old state most of the time and dumping stale information only serves to confuse people. Instead dump the new state just for the planes included in the operation. For now we'll include only the planes for the modeset/fastset pipes in the dumps. But probably we want to dump them all eventually, just not quite sure how to present that information nicely to the user. And while at it let's dump a few more interesting bits from the state.

Currently we're only dumping the failed crtc state if intel_modeset_pipe_config() fails. Let's do the state dump if anything else fails afterwards. The downside is that we lose the immediate knowledge which crtc caused the failure (unless a lower level function indicates it with an additional debug print) but having the full state dumped seems like something that could be beneficial.

Currently we're dumping the crtc states before they have been fully calculated. Move the dumping to the end of .atomic_check() so we get a fully up to date dump. Let's also do the dump for fully disabled pipes, but we'll limit that to just saying that the pipe is disabled since the rest of the state is going to be nonsense in that case. Signed-off-by:
