After commit 2cd9a689e97b ("drm/i915: Refactor intel_display_set_init_power() logic") it makes more sense to check the power domain/well refcounts after enabling the power domains functionality. Before that it's guaranteed that most power wells (in the INIT domain) will have a reference held, so not an interesting state. While at it also add the check after the init_hw/fini_hw, disable and suspend/resume steps. Make the test optional on a Kconfig option since it may add substantial overhead: on VLV/CHV the corresponding PUNIT reg access for each power well may take up to 20ms. v2: - Add the state check to more spots. (Chris) v3: - During suspend check the state before deiniting display core. Afterwards DC states are disabled (and so the dc_off power well is enabled) even though we don't hold a reference on it. - Do the test conditionally based on a new Kconfig option.

Not all chipsets have an internal buffer delaying the visibility of writes via the GGTT being visible by other physical paths, but we use a very heavy workaround for all. We only need to apply that workarounds to the chipsets we know suffer from the delay and the resulting coherency issue. Similarly, the same inconsistent coherency fouls up our ABI promise that a write into a mmap_gtt is immediately visible to others.

2018-07-19drm/i915: Nuke the LVDS lid notifierVille Syrjälä1-10/+0
We broke the LVDS notifier resume thing in (presumably) commit e2c8b8701e2d ("drm/i915: Use atomic helpers for suspend, v2.") as we no longer duplicate the current state in the LVDS notifier and thus we never resume it properly either. Instead of trying to fix it again let's just kill off the lid notifier entirely. None of the machines tested thus far have apparently needed it. Originally the lid notifier was added to work around cases where the VBIOS was clobbering some of the hardware state behind the driver's back, mostly on Thinkpads. We now have a few report of Thinkpads working just fine without the notifier. So maybe it was misdiagnosed originally, or something else has changed (ACPI video stuff perhaps?). If we do end up finding a machine where the VBIOS is still causing problems I would suggest that we first try setting various bits in the VBIOS scratch registers. There are several to choose from that may instruct the VBIOS to steer clear.

On an aborted module load, we unwind and free our device private - but we left a dangling pointer to our privates inside the pci_device. After the attempted aborted unload, we may still get a call to i915_pci_remove() when the module is removed, potentially chasing stale data.

commit b2209e62a450 ("drm/i915/execlists: Reset the CSB head tracking on reset/sanitization") and commit 1288786b18f7 ("drm/i915: Move GEM sanitize from resume_early to resume") show the conflicting requirements on the code. We must reset the GPU before trashing live state on a fast resume (hibernation debug, or error paths), but we must only reset our state tracking iff the GPU is reset (or power cycled). This is tricky if we are disabling GPU reset to simulate broken hardware; we reset our state tracking but the GPU is left intact and recovers from its stale state. v2: Again without the assertion for forcewake, no longer required since commit b3ee09a4de33 ("drm/i915/ringbuffer: Fix context restore upon reset") as the contexts are reset from the CS ensuring everything is powered up.

This should be a no-op in terms of our control flow, we move the sanitization (GPU reset) from the bottom of the early resume phase to the top of the next. However, following hibernation debug, the power code skips the early resume phase, but as we are about to completely restore the GTT mappings, we first need to stop the GPU using them i.e. perform a GPU reset (i915_gem_sanitize()).

Use intel_pch_type() also for mapping the no PCH case (PCH id 0) to PCH_NONE to simplify code. Also make sure that intel_pch_type() knows all the PCH ids returned by intel_virt_detect_pch(). Loudly fail if this isn't the case; this shouldn't happen anyway.

2018-06-11drm/i915: fix guest virtual PCH detection on non-PCH systemsJani Nikula1-1/+1
Virtualized non-PCH systems such as Broxton or Geminilake should use PCH_NONE to indicate no PCH rather than PCH_NOP. The latter is a specific case to indicate a PCH system without south display.

2018-06-06drm/i915: Mark i915.inject_load_failure as being hitChris Wilson1-5/+5
When we reach the magic value and do inject a fault into our module load, mark the module option as being hit. Since we fail from inside pci probe, the module load isn't actually aborted and the module (and parameters) are left lingering. igt can then inspect the parameter on its synchronous completion of modprobe to see if the fault injection was successful, and will keeping on injecting new faults until the module succeeds in loading having surpassed the number of fault points. v2: Reset to 0 after being hit; Signed-off-by: Chris Wilson <[email protected]> Cc: Michał Winiarski <[email protected]> Cc: Imre Deak <[email protected]> Reviewed-by: Michał Winiarski <[email protected]> Reviewed-by: Michal Wajdeczko <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
