Implement Dynamic Profiling, a ddb(4) based & gprof compatible kernel2017-02-06T09:13:41Zmpimpi@openbsd.org2017-02-06T09:13:41Zurn:sha1:178466ac14c42bc105d4a164b52d12261cbf9f18
profiling framework, for i386.
Code patching is used to enable probes when entering functions. The
probes will call a mcount()-like function to match the behavior of a
GPROF kernel.
A new sysctl knob, ddb.profile, need to be set to 1 in securelevel 0
to be able to use this feature.

Introduce Dynamic Profiling, a ddb(4) based & gprof compatible kernel2016-09-04T09:22:28Zmpimpi@openbsd.org2016-09-04T09:22:28Zurn:sha1:6950c8e205c43756d30d56ca678aa8205e9896fa
profiling framework.
Code patching is used to enable probes when entering functions. The
probes will call a mcount()-like function to match the behavior of a
GPROF kernel.
Currently only available on amd64 and guarded under DDBPROF. Support
for other archs will follow soon.
A new sysctl knob, ddb.console, need to be set to 1 in securelevel 0
to be able to use this feature.
