| * | x86: Add NMI duration tracepoints | Dave Hansen | 2013-06-23 | 1 | -0/+43 |
| This patch has been invaluable in my adventures finding issues in the perf NMI handler. I'm as big a fan of printk() as anybody is, but using printk() in NMIs is deadly when they're happening frequently. Even hacking in trace_printk() ended up eating enough CPU to throw off some of the measurements I was making.
