2019-01-25drm/i915: Don't try to use the hardware frame counter with i965gm TV outputVille Syrjälä
On i965gm the hardware frame counter does not work when the TV encoder is active. So let's not try to consult the hardware frame counter in that case. Instead we'll fall back to the timestamp based guesstimation method used on gen2. Note that the pipe timings generated by the TV encoder are also rather peculiar. Apparently the pipe wants to run at a much higher speed (related to the oversample clock somehow it seems) but during the vertical active period the TV encoder stalls the pipe every few lines to keep its speed in check. But once the vertical blanking period is reached the pipe gets to run at full speed. This means our vblank timestamp estimates are suspect. Fixing all that would require quite a bit more work. This simple fix at least avoids the nasty vblank timeouts that are happening currently. Curiously the frame counter works just fine on i945gm and gm45. I don't really understand what kind of mishap occurred with the hardware design on i965gm. Sadly I wasn't able to find any chicken bits etc. that would fix the frame counter :( v2: Move the zero vs. non-zero hw counter value handling into i915_get_vblank_counter() (Daniel) Use the per-crtc maximum exclusively, leaving the per-device maximum at zero v3: max_vblank_count not populated yet in intel_enable_pipe() use intel_crtc_max_vblank_count() instead Cc: stable@vger.kernel.org Cc: Daniel Vetter <daniel@ffwll.ch> Fixes: 51e31d49c890 ("drm/i915: Use generic vblank wait") Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=93782 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190122125149.GE5527@ideak-desk.fi.intel.com Reviewed-by: Imre Deak <imre.deak@intel.com>

2019-01-25drm/i915: Remove GPU reset dependence on struct_mutexChris Wilson
Now that the submission backends are controlled via their own spinlocks, with a wave of a magic wand we can lift the struct_mutex requirement around GPU reset. That is we allow the submission frontend (userspace) to keep on submitting while we process the GPU reset as we can suspend the backend independently. The major change is around the backoff/handoff strategy for performing the reset. With no mutex deadlock, we no longer have to coordinate with any waiter, and just perform the reset immediately.

2019-01-25drm/i915/guc: Disable global resetChris Wilson
The guc (and huc) currently inexcruitably depend on struct_mutex for device reinitialisation from inside the reset, and indeed taking any mutex here is verboten (as we must be able to reset from underneath any of our mutexes). That makes recovering the guc unviable without, for example, reserving contiguous vma space and pages for it to use. The plan to re-enable global reset for the GuC centres around reusing the WOPM reserved space at the top of the aperture (that we know we can populate a contiguous range large enough to dma xfer the fw image). In the meantime, hopefully no one even notices as the device-reset is only used as a backup to the per-engine resets for handling GPU hangs.

Make the defines for LE and L3 caching options to contain the shifts and remove the zeros from the tables as shifting zeros always result in zero. Starting from Ice Lake the MOCS table is defined in the spec and contains all entries. So to simplify checking the table with the values set in code, the value is now part of the macro name. This allows to still give the most used option and sensible name, but also to easily cross check the table from the spec for gen >= 11. By removing the zeros we avoid maintaining a huge table since the one from spec contains many more entries. The new table for Ice Lake will be added by other patches, this only reformats the table.

The bindings for Qualcomm opp levels changed after being Acked but before landing. Thus the code in the GPU driver that was relying on the old bindings is now broken.

NOTE: we will do additional cleanup to totally remove the string from the code and use the new dev_pm_opp_get_level() but we'll do it in a future patch. This will facilitate getting the important code fix in sooner without having to deal with cross-maintainer dependencies.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

2019-01-24drm/i915: Enable fastset for non-boot modesets.Maarten Lankhorst
Now that our state comparison functions are pretty complete, we should enable fastset by default when a modeset can be avoided. Even if we're not completely certain about the inherited state, we can be certain after the first modeset that our sw state matches the hw state. There is one testcase explicitly testing fastset, kms_panel_fitting.atomic-fastset but other testcases do so indirectly because most tests don't clean up the display during exit, or otherwise indirectly preserve mode by doing igt_display_reset or inheriting during init.

2019-01-24drm/i915/backlight: Fix backlight takeover on LPT, v3.Maarten Lankhorst
On lynxpoint the bios sometimes sets up the backlight using the CPU display, but the driver expects using the PWM PCH override register. Read the value from the CPU register, then convert it to the other units by converting from the old duty cycle, to freq, to the new units. This value is then programmed in the override register, after which we set the override and disable the CPU display control. This allows us to switch the source without flickering, and make the backlight controls work in the driver. Changes since v1: - Read BLC_PWM_CPU_CTL2 to cpu_ctl2. - Clean up cpu_mode if slightly. - Always disable BLM_PWM_ENABLE in cpu_ctl2.
