Subject: [PATCH v1 1/4] powerpc/pseries: hvcall.h: add H_WATCHDOG opcode, H_NOOP return code
Date: Fri, 20 May 2022 12:20:52 -0500	[thread overview]
Message-ID: <20220520172055.32220-1-cheloha@linux.ibm.com> (raw)

PAPR v2.12 defines a new hypercall, H_WATCHDOG.  The hypercall permits
guest control of one or more virtual watchdog timers.

Add the opcode for the H_WATCHDOG hypercall to hvcall.h.  While here,
add a definition for H_NOOP, a possible return code for H_WATCHDOG.
