Subject: [PATCH v3 0/2] OMAP: IOMMU fault callback support
Date: Wed, 16 Feb 2011 21:35:49 +0200 [thread overview]
Message-ID: <1297884951-3019-1-git-send-email-dacohen@gmail.com> (raw)
Hi,
This patch set adapts current (*isr)() to be used as fault callback.
IOMMU faults might be very difficult to reproduce and then to figure out
the source of the problem. Currently IOMMU driver prints not so useful
debug message and does not notice user about such issue.
With a fault callback, IOMMU user may debug much more useful information
and/or react to go back to a valid state.
Br,
David
