Subject: [PATCH v7 10/13] coresight: etm3x: change drvdata->spinlock type to raw_spin_lock_t
Date: Tue, 19 May 2026 16:48:09 +0100 [thread overview]
Message-ID: <20260519154812.254884-11-yeoreum.yun@arm.com> (raw)
In-Reply-To: <20260519154812.254884-1-yeoreum.yun@arm.com>
etm_starting_cpu()/etm_dying_cpu() are called in not sleepable context.
This poses an issue in PREEMPT_RT kernel where spinlock_t is sleepable.
To address this, change etm3's drvdata->spinlock type to raw_spin_lock_t.
This will be good to align with etm4x.
