Subject: [PATCH v2 3/5] pnv/xive2: Allow writes to the Physical Thread Enable registers
Date: Thu,  1 Jun 2023 14:13:29 +0200	[thread overview]
Message-ID: <20230601121331.487207-4-fbarrat@linux.ibm.com> (raw)
In-Reply-To: <20230601121331.487207-1-fbarrat@linux.ibm.com>

Fix what was probably a silly mistake and allow to write the Physical
Thread enable registers 0 and 1. Skiboot prefers to use the ENx_SET
variant so it went unnoticed, but there's no reason to discard a write
to the full register, it is Read-Write.

Fixes: da71b7e3ed45 ("ppc/pnv: Add a XIVE2 controller to the POWER10 chip")
