Subject: [PATCH 0/3] Fixes for HPD
Date: Fri, 17 Jun 2016 17:58:21 -0400 [thread overview]
Message-ID: <1466200705-9405-1-git-send-email-cpaul@redhat.com> (raw)
These are a couple of patches intended to fix one of the big problems we have
with a lot of chipsets on i915 right now: in the various forms of suspend we
use in the driver, many of them break HPD while active and can lead to some
seriously confusing situations where they can't get their monitors to turn on.
The patches here for fixing Valleyview need to be used with Ville Syrjälä's
patchset for (partially?) preventing valleyview from getting in an infinite hpd
detect loop when doing polling:
https://patchwork.freedesktop.org/series/5884/
It should also be noted some of these are resends, since the original patches
never got picked up by patchwork
Lyude (3):
drm/i915/vlv: Make intel_crt_reset() per-encoder
drm/i915/vlv: Reset the ADPA in vlv_display_power_well_init()
drm/i915: Enable polling when we don't have hpd
