On ICL we have to make sure that we enable the AUX power domain in a controlled way (corresponding to the port's actual TypeC mode). Since the PPS lock - which takes an AUX power ref - is only needed on eDP on all platforms and eDP/DP on VLV/CHV avoid taking it in all other cases. v2: - Clarify commit log about the condition for taking the PPS lock.

The power get/put was added in commit 1c767b33 ("drm/i915: take display port power domain in DP HPD handler") Author: Imre Deak <imre.deak@intel.com> Date: Mon Aug 18 14:42:42 2014 +0300 to account for the HW access in ibx_digital_port_connected(). This latter call was in turn removed in commit 7d23e3c3 ("drm/i915: Cleaning up intel_dp_hpd_pulse") Author: Shubhangi Shrivastava <shubhangi.shrivastava@intel.com> Date: Wed Mar 30 18:05:23 2016 +0530 after which we didn't actually need the power reference. One way we are accessing the HW during HPD pulse handling is via DP AUX transfers, but the transfer function takes its own reference, so doesn't need the reference in intel_dp_hpd_pulse(). The other spot is in intel_psr_short_pulse()->intel_psr_disable_locked() but that can only happen when the panel is enabled with the corresponding modeset already holding the required power reference. v2: - Remove the unneeded power get/put from intel_psr_disable_locked(). (Ville) - Checkpatch commit quoting format fix in the commit log.

We don't need the AUX power for the whole duration of the detect, only when we're doing AUX transfers. The AUX transfer function takes its own reference on the AUX power domain already. The two places during detect which access display core registers (not specific to a pipe/port/transcoder) only need the power domain that is required for that access. That power domain is equivalent to the device global power domain on most platforms (enabled whenever we hold a runtime PM reference) except on CHV/VLV where it's equivalent to the display power well. Add a new power domain that reflects the above, and use this at the two spots accessing registers. With that we can avoid taking the AUX reference for the whole duration of the detect function. Put the domains asynchronously to avoid the unneeded on-off-on toggling. Also adapt the idea from with_intel_runtime_pm et al. for making it easy to write short sequences where a display power ref is needed. v2: (Ville) - Add with_intel_display_power() helper to simplify things. - s/bool res/bool is_connected/ Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Signed-off-by:

In a follow-up patch we will restrict holding the reference on the AUX power domain to the AUX transfer function. To avoid the unnecessary on-off-on power togglings drop the reference asynchronously. There is no reason we couldn't do this in general and also put the reference asynchronously in pps_unlock(); but that's a separate change that can be done as a follow-up.

It used to be handy that we only had a couple of headers, but over time i915_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed.

Looks like VBT contains again the wrong information about a port's TypeC legacy vs. DP-alt/TBT-alt type. There is no further issues after we notice this and fix it up, so tune down the WARN to be a a DRM_ERROR. This also avoids CI tainting the kernel and stopping the test run. v2: - Update also code coment accordingly.

Split the sideback declarations out of the ginormous i915_drv.h Signed-off-by:

Chris Wilson authored
As we now employ a very heavy pm_qos around the punit access, we want to minimise the number of synchronous requests by performing one for the whole punit sequence rather than around individual accesses. The sideband lock is used for this, so push the pm_qos into the sideband lock acquisition and release, moving it from the lowlevel punit rw routine to the callers. In the first step, we move the punit magic into the common sideband lock so that we can acquire a bunch of ports simultaneously, and if need be extend the workaround protection later. Signed-off-by:

Currently we enable FEC even when DSC is no used. While that is theoretically valid supposedly there isn't much of a benefit from this. But more importantly we do not account for the FEC link bandwidth overhead (2.4%) in the non-DSC link bandwidth computations. So the code may think we have enough bandwidth when we in fact do not.

bitfield.h defines FIELD_GET() and FIELD_PREP() macros to access bitfields using the mask alone, with no need for separate shift. Indeed, the shift is redundant. We define REG_FIELD_GET() and REG_FIELD_PREP() wrappers for the above, in part to force u32 and for consistency with REG_BIT() and REG_GENMASK(), but also as we'll need to redefine REG_FIELD_PREP() in follow-up work to make it produce integer constant expressions. For the most part, REG_FIELD_GET() is shorter than masking followed by shift, and arguably has more clarity. REG_FIELD_PREP() can get more verbose than simply shifting in place, but it does provide masking to ensure we don't overflow the mask, something we usually don't bother with currently. Convert power sequencer registers as an example. v3: - temp variable removal (Chris) - rebase v2: - Add the REG_FIELD_GET() and REG_FIELD_PREP() wrappers to use them consistently from the start.
