[5.15.y backport 0/1] Disable IRQ1 wakeup on CZN systems for s2idle

by Mario Limonciello

A number of Cezanne systems report IRQ1 as a wakeup source when it's not actually a wakeup. This can cause problems for certain ACPI events. The following fix went upstream that fixed it: commit 8e60615e8932 ("platform/x86/amd: pmc: Disable IRQ1 wakeup for RN/CZN") It was reported that this fix actually helped here with older kernels too: Link: https://gitlab.freedesktop.org/drm/amd/-/issues/1921#note_1770257 So backport this fix to 5.15.y as well. The backport is done by hand because the driver has changed significantly. To backport this also requires the SMU version reading function which was introduced from: commit f6045de1f532 ("platform/x86: amd-pmc: Export Idlemask values based on the APU") So backport that part of that commit as well.

[PATCH] drm: Disable dynamic debug as broken

by Jani Nikula

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> CONFIG_DRM_USE_DYNAMIC_DEBUG breaks debug prints for (at least modular) drm drivers. The debug prints can be reinstated by manually frobbing /sys/module/drm/parameters/debug after the fact, but at that point the damage is done and all debugs from driver probe are lost. This makes drivers totally undebuggable. There's a more complete fix in progress [1], with further details, but we need this fixed in stable kernels. Mark the feature as broken and disable it by default, with hopes distros follow suit and disable it as well.

The problem is now that when anybody iterates over the DRM framebuffers and exports the underlying GEM objects through DMA-buf we run into a circular reference count situation. The result is that the fbdev handling holds the GEM handle preventing the DMA-buf in the GEM object to be released. This DMA-buf in turn holds a reference to the driver module which on unload would release the fbdev. Break that loop by releasing the handle as soon as the DRM framebuffer object is created. The DRM framebuffer and the DRM client buffer structure still hold a reference to the underlying GEM object preventing its destruction.
