Still chasing the mystery of the stray idle flush, let's ensure that the heartbeat does not run at the same time as our test and confuse us. References: https://gitlab.freedesktop.org/drm/intel/issues/541Signed-off-by:

Attaching to the i915_active barrier is a two stage process, and a flush is only effective when the barrier is activation. Thus it is possible for us to see a barrier, and attempt to flush, only for our flush to have no effect. As such, before attempting to activate signaling on the fence we need to double check it is a fence!

On TGL, bits 2-4 in the GGTT PTE are not ignored anymore and are instead used for some extra VT-d capabilities. We don't (yet?) have support for those capabilities, but, given that we shared the pte_encode function betweed GGTT and PPGTT, we still set those bits to the PPGTT PPAT values. The DMA engine gets very confused when those bits are set while the iommu is enabled, leading to errors. E.g. when loading the GuC we get: [ 9.796218] DMAR: DRHD: handling fault status reg 2 [ 9.796235] DMAR: [DMA Write] Request device [00:02.0] PASID ffffffff fault addr 0 [fault reason 02] Present bit in context entry is clear [ 9.899215] [drm:intel_guc_fw_upload [i915]] *ERROR* GuC firmware signature verification failed To fix this, just have dedicated gen8_pte_encode function per type of gtt. Also, explicitly set vm->pte_encode for gen8_ppgtt, even if we don't use it, to make sure we don't accidentally assign it to the GGTT one, like we do for gen6_ppgtt, in case we need it in the future.

Wa_1608008084 is an additional WA that applies to writes on FF_MODE2 register. We can't read it back either from CPU or GPU. Since the other bits should be 0, recommendation to handle Wa_1604555607 is to actually just write the timer value. Do a write only and don't try to read it, neither before or after the WA is applied. Fixes: ff690b21 ("drm/i915/tgl: Implement Wa_1604555607") Signed-off-by:

Looks like the pipe rounding mode bit has moved from PIPE_CHICKEN to PIPE_MISC on tgl. Frob the new location. Bspec does still document the old bits as well, so I left the code for them as is until we get clarification from the hw folks on whether the old bits still do something useful. Signed-off-by:

The implicit "dev_priv" local variable use has been a long-standing pain point in the register access macros I915_READ(), I915_WRITE(), POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW(). Replace the sole remaining I915_WRITE() in i915_drv.c with intel_uncore_write(), although it might be better to keep the entire file void of direct register access. No functional changes.

Commit 60c6a14b ("drm/i915/display: Force the state compute phase once to enable PSR") was forcing the state compute too earlier causing errors because not everything was initialized, so here moving to the end of i915_driver_modeset_probe() when the display is all initialized. Also fixing the place where it disarm the force probe as during the atomic check phase errors could happen like the ones due locking and it would cause PSR to never be enabled if that happens. Leaving the disarm to the atomic commit phase, intel_psr_enable() or intel_psr_update() will be called even if the current state do not allow PSR to be enabled. v2: Check if intel_dp is null in intel_psr_force_mode_changed_set() v3: Check intel_dp before get dev_priv v4: - renamed intel_psr_force_mode_changed_set() to intel_psr_set_force_mode_changed() - removed the set parameter from intel_psr_set_force_mode_changed() - not calling intel_psr_set_force_mode_changed() from intel_psr_enable/update(), directly setting it after the same checks that intel_psr_set_force_mode_changed() does - moved intel_psr_set_force_mode_changed() arm call to i915_driver_modeset_probe() as it is a better for a PSR call, all the functions calls happening between the old and the new function call will cause issue Fixes: 60c6a14b ("drm/i915/display: Force the state compute phase once to enable PSR") Closes: https://gitlab.freedesktop.org/drm/intel/issues/1151Tested-by:
