71b54dd48a Always collect thread names. 
This fixes an issue when a thread was destroyed before its name could be
retrieved.

5e199d1ab3 Support ftrace on ARM. 2019-08-14 16:28:54 +02:00
Bartosz Taudul
5fbb811f5d Degrade ARM timer to monotonic raw clock. 
The monotonic raw clock has the same accuracy as reading cntvct registers, but
using clock_gettime() has a measurable impact on queueing time (135 us vs
83 us).

This change is needed to enable ftrace time readings on ARM linux, which
doesn't provide any way to get raw cntvct readings, like x86-tsc on x86.

3996516fce One more SetThreadName() to change. 2019-08-14 02:27:01 +02:00
Bartosz Taudul
92b6da7cc2 SetThreadName() only works on the current thread. 
This breaking change is required, because kernel trace facilities use
kernel thread ids, which are inaccessible from the pthread_t level.

d6f32a0839 Serialize lock processing. 
This makes is much easier to process on the server and opens new
optimization possibilities. It also fixes theoretical problems, which
may be caused by invalid ordering of events with the same timestamp.
