[PATCH 5/8] kgdb,debug_core: Use atomic operators which use barriers
A cpu_relax() does not mandate that there is an smp memory barrier. As a result on the arm smp architecture the kernel debugger can hang on entry from time to time, as shown by the kgdb regression tests. The solution is simply to use the atomic operators which include a proper smp memory barrier, instead of using... 22 Mar 2010 15:31

Memory-mapped I/O barriers, state of affairs?
Hello, searching for good info on device IO racing against host memory writes I came upon this 2006 article: http://lwn.net/Articles/198988/ "there is no guaranteed ordering between writes to regular memory and writes to a memory-mapped I/O range. " What is the current solution for that particular problem... 22 Mar 2010 20:39
