To simplify things, call the combo PHY/TBT PLL calculation functions directly from the corresponding combo/TypeC PLL get functions, instead of calling the same calculation functions after having to recheck if the given PHY is combo or TypeC. Signed-off-by:

When the reference clock is 38.4MHz, using the current TBT PLL fractional divider value results in a slightly off TBT link frequency. This causes an endless loop of link training success followed by a bad link signaling and retraining at least on a Dell WD19TB TBT dock. The workaround provided by the HW team is to divide the fractional divider value by two. This fixed the link training problem on the ThinkPad dock. The same workaround is needed on some EHL platforms and for combo PHY PLLs, these will be addressed in a follow-up.

The obj->lut_list is traversed when the object is closed as the file table is destroyed during process termination. As this occurs before we kill any outstanding context if, due to some bug or another, the closure is blocked, then we fail to shootdown any inflight operations potentially leaving the GPU spinning forever. As we only need to guard the list against concurrent closures and insertions, the hold is short and merits being treated as a simple spinlock. Signed-off-by:

Rearrange the allocation of the mm_struct registration to avoid allocating underneath the i915->mm_lock, so that we avoid tainting the lock (and in turn many other locks that may be held as i915->mm_lock is taken, and those locks we may want on the free [shrinker] paths). In doing so, we convert the lookup to be RCU protected by courtesy of converting the free-worker to be an rcu_work. v2: Remember to use hash_rcu variants to protect the list iteration from concurrent add/del.

The default fbc1 compression interval we use is 500 frames. That translates to over 8 seconds typically. That's rather excessive so let's drop it to 1 second. The hardware will not attempt recompression unless at least one line has been modified, so a shorter compression interval should not cause extra bandwidth use in the purely idle scenario. Of course in the mostly idle case we are possibly going to recompress a bit more. Should really try to find some kind of sweet spot to minimize the energy usage... Signed-off-by:

The current fence_y_offset calculation is broken. I think it more or less used to do the right thing, but then I changed the plane code to put the final x/y source offsets back into the src rectangle so now it's just subtraacting the same value from itself. The code would never have worked if we allowed the framebuffer to have a non-zero offset. Let's do this in a better way by just calculating the fence_y_offset from the final plane surface offset. Note that we don't align the plane surface address to fence rows so with horizontal panning there's often a horizontal offset from the fence start to the surface address as well. We have no way to tell the hardware about that so we just ignore it. Based on some quick tests the invlidation still happens correctly. I presume due to the invalidation nuking at least the full line (or a segment of multiple lines). Fixes: 54d4d719 ("drm/i915: Overcome display engine stride limits via GTT remapping") Signed-off-by:

As we close a handle GEM object, we update the drm_file's idr with an error^W NULL pointer to indicate the in-progress closure, and finally removing it.

The linetime watermark is a 9 bit value, which gives us a maximum linetime of just below 64 usec. If the linetime exceeds that value we currently just discard the high bits and program the rest into the register, which angers the state checker. To avoid that let's just clamp the value to the max. I believe it should be perfectly fine to program a smaller linetime wm than strictly required, just means the hardware may fetch data sooner than strictly needed. We are further reassured by the fact that with DRRS the spec tells us to program the smaller of the two linetimes corresponding to the two refresh rates.

The DP spec says: "The transmitter shall support at least three levels of voltage swing (Levels 0, 1, and 2). If only three levels of voltage swing are supported (VOLTAGE SWING SET field (bits 1:0) are programmed to 10 (Level 2)), this bit shall be set to 1, and cleared in all other cases. If all four levels of voltage swing are supported (VOLTAGE SWING SET field (bits 1:0) are programmed to 11 (Level 3)), this bit shall be set to 1,and cleared in all other cases." Let's follow that exactly instead of the current apporach where we can set those also for vswing/preemph levels 0 or 1 (or 2 when the platform max is 3). Signed-off-by:

During transcoder enabling we'll configure the transcoder in MST mode and enable the VC payload allocation, which will start the ACT sequence. Before waiting for the ACT sequence completion, we need to clear the ACT sent flag, but based on the above we can do this right before enabling the transcoder. For clarity, move the flag clearing closer to where we wait for it. While at it also factor out some common code. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

During the initial probing of an MST sink, MST core will determine the sink's link bandwidth based on its own version of the sink link rate/lane count caps it reads from the DPCD. At a later point (after probing and 1 or more modesets) i915 may limit the link parameters wrt. the original source/sink common caps above due to link training failures during a modeset and the resulting link training fallback logic. Based on the above a modeset following another modeset with a link training error will compute the i915 HW specific and DP protocol timing parameters (data/link M/N and MST TU values) taking into account only the unlimited source/sink common caps, but not taking into account the fallback limits. This will also let DRM core oversubscribe the actual link bandwidth during the MST payload allocation. Prevent the above problem by disabling the link training fallback on MST links for now, until the MST probe time initialization and the MST compute config logic can deal with changing link parameters. The misconfigured timings lead at least to a 'Timed out waiting for DP idle patterns' error. v2: (Ville) - Print link training error message on the MST path too. - Clarify the problem in the commit log.

MST encoders must use the master MST transcoder's DP_TP_STATUS and DP_TP_CONTROL registers. Atm, during the HW readout of an MST encoder connected to a slave transcoder we reset these register addresses in intel_dp::regs.dp_tp_* to the slave transcoder's DP_TP_* register addresses incorrectly; fix this. One example where the above overwite happens is the encoder HW state validation after enabling multiple streams; see intel_dp_mst_enc_get_config(). After that during disabling any stream we'll get a 'Timed out waiting for ACT sent when disabling' error, due to reading from the incorrect DP_TP_STATUS register. This change replaces https://patchwork.freedesktop.org/patch/369577/?series=78193&rev=1 which just papered over the problem. v2: - Correct the failure scenario in the commit log.

Start using device specific parameters instead of module parameters for most things. The module parameters become the immutable initial values for i915 parameters. The device specific parameters in i915->params start life as a copy of i915_modparams. Any later changes are only reflected in the debugfs. The stragglers are: * i915.force_probe and i915.modeset. Needed before dev_priv is available. This is fine because the parameters are read-only and never modified. * i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and I915_STATE_WARN_ON would result in massive and ugly churn. This is handled by not exposing the parameter via debugfs, and leaving the parameter writable in sysfs. This may be fixed up in follow-up work. * i915.inject_probe_failure. Only makes sense in terms of the module, not the device. This is handled by not exposing the parameter via debugfs. v2: Fix uc i915 lookup code (Michał Winiarski) Cc: Juha-Pekka Heikkilä <juha-pekka.heikkila@intel.com> Cc: Venkata Sandeep Dhanalakota <venkata.s.dhanalakota@intel.com> Cc: Michał Winiarski <michal.winiarski@intel.com> Reviewed-by:

This userspace program includes UAPI headers exported to usr/include/. 'make headers' always works for the target architecture (i.e. the same architecture as the kernel), so the sample program should be built for the target as well. Kbuild now supports 'userprogs' for that. I also guarded the CONFIG option by 'depends on CC_CAN_LINK' because $(CC) may not provide libc. Signed-off-by:Masahiro Yamada <masahiroy@kernel.org>

This reverts commit e0b250b5, which broke build systems that need to install files to a certain path, but do not set INSTALL_MOD_PATH when invoking 'make install'. $ make INSTALL_PATH=/tmp/destdir install mkdir: cannot create directory ‘/lib/modules/5.8.0-rc1+/’: Permission denied Makefile:1342: recipe for target '_builtin_inst_' failed make: *** [_builtin_inst_] Error 1 While modules.builtin is useful also for CONFIG_MODULES=n, this change in the behavior is quite unexpected. Maybe "make modules_install" can install modules.builtin irrespective of CONFIG_MODULES as Jonas originally suggested. Anyway, that commit should be reverted ASAP. Reported-by:
