[GSoC] How RTEMS, GCC and newlib interact ?

I have some questions about how RTEMS, GCC, newlib interact with each other, and which parts of them should I care and know about when porting RTEMS to OpenRISC. For example, the newlib port for OpenRISC includes some functions that deal with interrupts, exceptions, writing to SPRs, Caches, MMU, e

Re: RTEMS Chain API and SMP

This will make the protected Chain API stuck (for now, possibly forever) with coarse-grained locks, but users can define their own fine-grained locking implementations of chains using unprotected chain API calls? I think this is acceptable. Gedare On Fri, Mar 7, 2014 at 11:12 AM, Sebastian Huber

RTEMS Chain API and SMP

Hello, I am glad that we had no RTEMS 4.11 release yet. I have to revisit the RTEMS chain API. This solution was a bad mistake as it runs out now: http://git.rtems.org/rtems/commit/cpukit/sapi/include/rtems/chain.h?id=1215fd4d9426a59d568560e9a485628560363133 In order to support profiling of
