Subject: [PATCH v6 21/25] iommu/tegra241-cmdqv: Use request_threaded_irq
Date: Sat, 14 Jun 2025 00:14:46 -0700 [thread overview]
Message-ID: <ef8bedbc09f8dd7103d915b646c4f5352cd00928.1749884998.git.nicolinc@nvidia.com> (raw)
In-Reply-To: <cover.1749884998.git.nicolinc@nvidia.com>
A vEVENT can be reported only from a threaded IRQ context. Change to using
request_threaded_irq to support that.
