[PATCH 1/5] drm/nouveau: Prevent RPM callback recursion in suspend/resume paths
...ate, so is waiting forever for the device to
runtime suspend in order to resume it again immediately afterwards.
The deadlock in the stack trace you've posted could be resolved using
the technique I used in d61a5c106351 by adding the following to
include/linux/pm_runtime.h:
static inline bool pm_runtime_status_suspending(struct device *dev)
{
return dev->power.runtime_status == RPM_SUSPENDING;
}
static inline bool is_pm_work(struct device *dev)
{
struct work_struct *work = current_work();
return work && work->func == dev->power.work;
}
Then adding this to nvkm_i2c_aux_acquire():
struct d...
