Subject: [PATCH v2 1/3] powerpc/ps3: Add CONFIG_PS3_VERBOSE_RESULT option
Date: Thu, 03 Jun 2021 19:17:01 +0000 [thread overview]
Message-ID: <0ce4b6969a08094a747bd382dbfd30b72ebc192d.1622746428.git.geoff@infradead.org> (raw)
In-Reply-To: <cover.1622746428.git.geoff@infradead.org>
To aid debugging, add a new PS3 kernel config option
PS3_VERBOSE_RESULT that, when enabled, will print more
verbose messages for the result of LV1 hypercalls.
Signed-off-by: Geoff Levand <geoff@infradead.org>
