2014-03-11score: Add local context to SMP lock APISebastian Huber
Add a local context structure to the SMP lock API for acquire and release pairs. This context can be used to store the ISR level and profiling information. It may be later used to enable more sophisticated lock algorithms, e.g. MCS locks. There is only one lock that cannot be used with a local context. This is the per-CPU lock since here we would have to transfer the local context through a context switch which is very complicated.
2013-09-05termios: check return value from semaphore obtain/releaseGedare Bloom
Raise a fatal error in case of failure.
2013-06-12termios: SMP supportSebastian Huber
2013-06-12termios: Notify driver about inactive transmitSebastian Huber
Returning this state in the return value leads to race conditions on SMP. The inactive state notification must be inside the critical section.
2013-06-12termios: Expand critical sectionSebastian Huber
Use interrupt disable/enable to protect the complete refill state change. This avoids race conditions for the task driven configuration and a later SMP support.

Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.
2012-04-03Filesystem: Change type of ioctl_returnSebastian Huber

* libcsupport/src/termios.c: Change attribute of semaphore. It was counting interrupts not acting as a condition synchronization mutex. Since the caller did not always need to obtain the semaphore, it was not being decremented until there was no data. This could occur after hours of running a system and thousands of interrupts. The code in fillBufferQueue would spin until it had consumed all of those semaphore counts.

* Nice Update of PPPD support which eliminates the requiremetn that drivers be in the termios TASK_DRIVEN mode. Mike did significant testing and reports that it seems to be more stable and handle larger packets better. This patch replaces the termios tasks with more general pppd network driver tasks. The functions pppinput() and pppstart() get called from the interrupt service routine. * libc/termios.c: Added PPCDISC.

* libc/termios.c: Fixed a memory leak in the termios software.

I know the termios buffer has more than one character available and my read() call is requesting 1024 bytes.
