ADL-S requires TC pins to set up ddc for Combo PHY B, C, D and E. Combo PHY A still uses the old ddc pin mapping. From VBT, ddc pin info suggests the following mapping: VBT DRIVER DDI B->ddc_pin=2 should translate to PORT_D->0x9 DDI C->ddc_pin=3 should translate to PORT_E->0xa DDI D->ddc_pin=4 should translate to PORT_F->0xb DDI E->ddc_pin=5 should translate to PORT_G->0xc Adding pin map to facilitate this translation as we cannot use existing icl ddc pin map due to conflict with DDI B and DDI C info.

TGL adds another level of indirection for applying WA based on stepping information rather than PCI REVID. So change TGL_REVID enum into stepping enum and use PCI REVID as index into revid to stepping table to fetch correct display and GT stepping for application of WAs as suggested by Matt Roper.

GuC owns the execlists state and the context IDs used for submission, so the status of the ports and the CSB entries are not something we control or can decode from the i915 side, therefore we can avoid dumping it.

Delete GuC code unused in future patches that rewrite the GuC interface to work with the new firmware. Most of the code deleted relates to workqueues or execlist port. The code is safe to remove because we still don't allow GuC submission to be enabled, even when overriding the modparam, so it currently can't be reached. The defines + structs for the process descriptor and workqueue remain. Although the new GuC interface does not require either of these for the normal submission path multi-lrc submission does. The usage of the process descriptor and workqueue for multi-lrc will be quite different from the code that is deleted in this patch. A future patch will implement multi-lrc submission. v2: add a code in the commit message about the code being safe to remove (Chris) Signed-off-by:

During igt_reset_nop_engine, it was observed that an unexpected failed engine reset lead to us busywaiting on the stop-ring semaphore (set during the reset preparations) on the first request afterwards. There was no explicit MI_ARB_CHECK in this sequence as the presumption was that the failed MI_SEMAPHORE_WAIT would itself act as an arbitration point. It did not in this circumstance, so force it. This patch is based on the assumption that the MI_SEMAPHORE_WAIT failure to arbitrate is a rare Tigerlake bug, similar to the lite-restore vs semaphore issues previously seen in the CS. The explicit MI_ARB_CHECK should always ensure that there is at least one arbitration point in the request before the MI_SEMAPHORE_WAIT to trigger the IDLE->ACTIVE event. Upon processing that event, we will clear the stop-ring flag and release the semaphore from its busywait. Signed-off-by:

The clear-residuals mitigation is a relatively heavy hammer and under some circumstances the user may wish to forgo the context isolation in order to meet some performance requirement. Introduce a generic module parameter to allow selectively enabling/disabling different mitigations. To disable just the clear-residuals mitigation (on Ivybridge, Baytrail, or Haswell) use the module parameter: i915.mitigations=auto,!residuals Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/1858 Fixes: 47f8253d ("drm/i915/gen7: Clear all EU/L3 residual contexts") Signed-off-by:
