Hi Jani, Ville, Arun, This patchset is replacement of patch "drm/i915/display: disable HPD workers before display driver unregister" [1]. Ive decided to split patch into two parts - fbdev and MST, there are different issues. Ive also dropped shutdown path, as it has slightly different requirements, and more importantly I am not able to test properly. v2 (thx Arun for review): - reword of commit message (Arun) - intel_fbdev_hpd_set_suspend replaced with intel_fbdev_set_suspend (Arun) v3: - new patch adding suspended flag, to handle https://gitlab.freedesktop.org/drm/intel/-/issues/5950 v4: - check suspend flag also in i915_digport_work_func v5: - added patch blocking FB creation in case HPD is supended, - added R-B from Arun to patch 3, thx v6: - finally, after getting direct access to bat-rpls-2, I have found the source of last WARN, intel_fbdev_hpd_set_suspend was not called in case of deferred setup, fixed in patch 2.
