Subject: [patch 0/2] Run interrupt handlers always with interrupts disabled
Date: Fri, 26 Mar 2010 00:06:44 -0000 [thread overview]
Message-ID: <20100326000325.917127328@linutronix.de> (raw)
The following patch series removes the IRQF_DISABLED functionality
from the core interrupt code and runs all interrupt handlers with
interrupts disabled.
IRQF_DISABLED is kept as a define and scheduled for feature removal.
I booted and stressed that patches w/o any obvious fallout on more
than 20 different systems in my arsenal of test machines which
includes various embedded non x86 systems.
To debug eventual latency issues we (admittedly I talked acme into
looking at that) want to extend perf with a top like tool to monitor
the maximum runtime of interrupt handlers with the already existing
tracepoints.
Thanks,
tglx
