Subject: [PATCH v3 3/6] powerpc/64: Add logical PVR to the hardware description
Date: Fri, 30 Sep 2022 18:27:06 +1000 [thread overview]
Message-ID: <20220930082709.55830-3-mpe@ellerman.id.au> (raw)
In-Reply-To: <20220930082709.55830-1-mpe@ellerman.id.au>
If we detect a logical PVR add that to the hardware description, which
is printed at boot and in case of an oops.
eg: Hardware name: ... 0xf000004
