... LWN.net FAQ . ... Read-copy-update (RCU) is a mutual exclusion technique which can operate without locking most of the time. It can yield significant performance benefits when the data to be protected is accessed via a pointer, is read frequently, changed rarely, and references to the structure are not held while a kernel thread sleeps. The core idea behind RCU is that, when the data requires updating, a pointer to a new structure containing the new data can be stored immediately. ...

The vertex software has encoder corrections that can be interactively modified via the ocu or lcu interface. ... When adding a correction, the display position includes the correction. Preset mode works fine with the correction (eg. start at 270, add correction=1deg, display reads 271, preset to 270 moves the telescope be 1 degree). I think that program track mode works differently with the offsets.. mainly because we had an offset of 1 degree for 5 months and we could still see sources. ...
