Subject: [PATCH v2 6/6] powerpc/pseries: Add firmware details to the hardware description
Date: Thu, 29 Sep 2022 23:59:19 +1000 [thread overview]
Message-ID: <20220929135919.1983269-6-mpe@ellerman.id.au> (raw)
In-Reply-To: <20220929135919.1983269-1-mpe@ellerman.id.au>
Add firmware version details to the hardware description, which is
printed at boot and in case of an oops.
Use /hypervisor if we find it, though currently it only exists if we're
running under qemu.
Look for "ibm,powervm-partition" which is specified in PAPR+ v2.11 and
tells us we're running under PowerVM.
Failing that look for "ibm,fw-net-version" which is seen on PowerVM
going back to at least Power6.
eg: Hardware name: ... of:'IBM,FW860.42 (SV860_138)' hv:'phyp'

v2: Look for "ibm,powervm-partition" as suggested by Nathan.
