Subject: 答复: 答复: [PATCH] kdb: Fix the deadlock issue in KDB debugging.
Date: Tue, 12 Mar 2024 08:37:11 +0000 [thread overview]
Message-ID: <2ea381e7407a49aaa0b08fa7d4ff62d3@h3c.com> (raw)
In-Reply-To: <20240301105931.GB5795@aspen.lan>
I know that you said schedule_work is not NMI save, which is the first issue. Perhaps it can be fixed using irq_work_queue. But even if irq_work_queue is used to implement it, there will still be a deadlock problem because slave cpu1 still has not released the running queue lock of master CPU0.
