2019-04-10drm/i915/icl: Don't warn on spurious interruptsMika Kuoppala1-7/+1
There is a chance we can see spurious interrupts in live now. We have more engines enabled and that with more elaborate access patterns with pm and display, increases the chances hardware just makes a social call, without anything to work on. Remove the error as we have tests to actually probe if we really miss interrupt, instead of getting spurious ones. Note that now we do write to intr_dw even with a zero value. This is considered advantegous as the write is an ack that sw is done.

Commit 7769db588384 ("drm/i915/dp: optimize eDP 1.4+ link config fast and narrow") started to optize the eDP 1.4+ link config, both per spec and as preparation for display stream compression support.

Push getting the reference for the encoders' power domains into the encoder get_power_domains() hook instead of doing this from the caller.

A couple of machines in the farm show quite frequent errors in the powerwells not being released. Either there is an external agent interferring with the powerwells, or the powerwell doesn't quite behave as we anticipate -- either way, the test is not reliable enough to be enabled by default in CI. It has served its immediate purpose in providing coverage as we made tweaks to forcewake, so keep it available for future testing.

The only bpc information in pipe registers for BXT/GLK DSI is the PIPEMISC dither bpc. Let's try to use that to read out pipe_bpp on these platforms. However, I'm not sure if this will be correctly populated by the GOP since bspec suggests it's only needed if dithering is actually enabled.

2019-04-08drivers: Remove explicit invocations of mmiowb()Will Deacon1-10/+0
mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

2019-04-08drm/i915/cdclk: have only one init/uninit functionJani Nikula3-88/+58
While transitioning to having better clarity between the modules, it's desirable to have the function name prefixes reflect the module. Functions in intel_foo.c should be prefixed intel_foo_. Expose only one CDCLK init/uninit function from intel_cdclk.c instead of one per platform. Obviously this adds one "unnecessary" if ladder within the entry points. However it should be considered more of a CDCLK implementation detail how this is done per platform, instead of exposing the fact. In other words, abstract the CDCLK module better.

2019-04-08drm/i915: Fix pipe_bpp readout for BXT/GLK DSIVille Syrjälä1-0/+24
The only bpc information in pipe registers for BXT/GLK DSI is the PIPEMISC dither bpc. Let's try to use that to read out pipe_bpp on these platforms. However, I'm not sure if this will be correctly populated by the GOP since bspec suggests it's only needed if dithering is actually enabled. If not I guess we'll have to go one step further and extract pipe_bpp from the DSI pixel format when dithering is disabled.

ppgtt_free_all_spt() iterates the radixtree as it is deleting it, forgoing all protection against the leaves being freed in the process (leaving the iter pointing into the void). A minimal fix seems to be to use the available post_shadow_list to decompose the tree into a list prior to destroying the radixtree.

2019-04-07drm/i915: Track the temporary wakerefs used for hsw_get_pipe_configChris Wilson1-13/+33
Haswell+ require many power wells to probe the current HW display state. Under the wakeref tracking scheme, we want each owner to store and release the wakeref they use, so we can identify callers that have leaked their wakeref. For hsw_get_pipe_config, this means we have to keep the array of all wakerefs as it current acquires its power wells piecemeal and releases them en masse. By tracking these wakerefs, we should be able to eliminate a lot of noise from the runtime-pm debug logs.

As soon as a device is considered unplugged, not only prevent pending users from accessing the device structures but also cancel all their pending requests so all consumed resources can be cleaned up as soon as possible.
