Subject: [PATCH v6 46/52] opp: Put interconnect paths outside of opp_table_lock
Date: Mon, 26 Oct 2020 01:17:29 +0300 [thread overview]
Message-ID: <20201025221735.3062-47-digetx@gmail.com> (raw)
In-Reply-To: <20201025221735.3062-1-digetx@gmail.com>
This patch fixes lockup which happens when OPP table is released if
interconnect provider uses OPP in the icc_provider->set() callback
and bandwidth of the ICC path is set to 0 by the ICC core when path
is released. The icc_put() doesn't need the opp_table_lock protection,
hence let's move it outside of the lock in order to resolve the problem.
In particular this fixes tegra-devfreq driver lockup on trying to unload
the driver module. The devfreq driver uses OPP-bandwidth API and its ICC
provider also uses OPP for DVFS, hence they both take same opp_table_lock
when OPP table of the devfreq is released.
