This patch adds a debugfs interface to force scheduling a recovery event. This can be used to recover a specific PE or schedule a "special" recovery even that checks for errors at the PHB level. To force a recovery of a normal PE, use: echo '<#pe>:<#phb>' > /sys/kernel/debug/powerpc/eeh_force_recover To force a scan for broken PHBs: echo 'hwcheck' > /sys/kernel/debug/powerpc/eeh_force_recover Signed-off-by: Oliver O'Halloran <oohall@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
