Subject: [PATCH v4 0/3] rust: Add irq abstraction, SpinLockIrq
Date: Wed, 11 Sep 2024 20:55:31 -0400 [thread overview]
Message-ID: <20240912005539.175428-1-lyude@redhat.com> (raw)
This adds a simple interface for disabling and enabling CPUs, along with
the ability to mark a function as expecting interrupts be disabled -
along with adding bindings for spin_lock_irqsave/spin_lock_irqrestore().
Current example usecase (very much WIP driver) in rvkms:
