Christian Hergert	69e4fb2588	libsysprof-capture: allow using ring in readwrite mode ... This is a first step to be able to use the ring buffer as the backing buffer for the SysprofCaptureWriter.	2020-02-15 22:50:22 -07:00
Christian Hergert	e3ed30eb48	libsysprof-capture: remove framing data from MappedRingBuffer ... This removes the 8 bytes of framing data from the MappedRingBuffer which means we can write more data without racing. But also this means that we can eventually use the mapped ring buffer as our normal buffer for capture writing (to be done later).	2020-02-15 20:46:05 -07:00
Christian Hergert	77400c57c1	libsysprof-capture: add mmap()'d ring buffer ... This is the start of a ring buffer to coordinate between processes without the overhead of writing directly to files within the inferior process. Instead, the parent process can monitor the ring buffer for framing information and pass that along to the capture writer.	2020-02-13 18:50:20 -08:00
