Subject: [PATCH 07/13] m68k: sun3/sun3c: use legacy_timer_tick
Date: Thu, 8 Oct 2020 17:46:45 +0200 [thread overview]
Message-ID: <20201008154651.1901126-8-arnd@arndb.de> (raw)
In-Reply-To: <20201008154651.1901126-1-arnd@arndb.de>
These two are different from all other machines:
* sun3 does not call timer_routine() but open-codes it
except for the profile_tick() call that appears to
be unintentionally missing.
* sun3x has a commented-out timer irq handler but no
functional timer tick I could find.
Change both to calling the new legacy_timer_tick here,
which includes the call to profile_tick() but does not
fix sun3x as that is still commented out.
