[PATCH 12/14] powerpc/eeh: Add debugfs interface to run an EEH check

2019-09-03 Thread Oliver O'Halloran
Detecting an frozen EEH PE usually occurs when an MMIO load returns a 0xFFs response. When performing EEH testing using the EEH error injection feature available on some platforms there is no simple way to kick-off the kernel's recovery process since any accesses from userspace (usually /dev/mem) w
