Subject: [PATCH v4 21/26] iommu/arm-smmu-v3: Ratelimit event dump
Date: Mon, 24 Feb 2020 19:23:56 +0100 [thread overview]
Message-ID: <20200224182401.353359-22-jean-philippe@linaro.org> (raw)
In-Reply-To: <20200224182401.353359-1-jean-philippe@linaro.org>
When a device or driver misbehaves, it is possible to receive events
much faster than we can print them out. Ratelimit the printing of
events.
Signed-off-by: Jean-Philippe Brucker <jean-philippe@linaro.org>
---
During the SVA tests when the device driver didn't properly stop DMA
before unbinding, the event queue thread would almost lock-up the server
with a flood of event 0xa. This patch helped recover from the error.
