| |
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
