Subject: [PATCH v1 1/4] powerpc/pseries: hvcall.h: add H_WATCHDOG opcode, H_NOOP return code
Date: Fri, 20 May 2022 13:35:49 -0500 [thread overview]
Message-ID: <20220520183552.33426-2-cheloha@linux.ibm.com> (raw)
In-Reply-To: <20220520183552.33426-1-cheloha@linux.ibm.com>
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.
