- Subbuffer size in bytes (default: 4096, kernel default: 262144)
- Needs to be a power of 2 for both tracers
+ Subbuffer size in bytes {+k,+M,+G}
+ (default UST uid: 131072, UST pid: 4096, kernel: 262144, metadata: 4096)
+ Rounded up to the next power of 2.
+
+ The minimum subbuffer size, for each tracer, is the max value between
+ the default above and the system page size. You can issue this command
+ to get the current page size on your system: \fB$ getconf PAGE_SIZE\fP
