Subject: [RFC v8 13/20] um: lkl: integrate with irq infrastructure of UML
Date: Wed, 20 Jan 2021 11:27:18 +0900 [thread overview]
Message-ID: <46935454bf02224fb325f0e74d60d0ed674a59f9.1611103406.git.thehajime@gmail.com> (raw)
In-Reply-To: <cover.1611103406.git.thehajime@gmail.com>
In order to cooperate with UML's irq infrastructure and LKL threads
based on host threads, irq handlers shall synchronize the our
scheduler which is controlled by struct lkl_cpu. To do that, the irq
infra notifies its entry of handlers by obtaining cpu access of thread
scheduler (lkl_cpu_try_run_irq) and its release (lkl_cpu_put).
In additon to that, in order to stick the signal handler's thread to the
one of the idle thread, several required configurations of (thread's)
signal mask are added: otherwise handlers running on arbitrary thread
cannot obtain cpu access and immediately fall into pending interrupt
which may slow down the delivery of signals.
