The X.2 interface was designed such that a mapping of V2 -> X.2 is possible via wrapper functions. The fixed thread/task model can be emulated and ex-regs etc can be mapped as well. Main problem is the IDL compiler; not sure if Dice supports X.2... Ron? - Volkmar

[EMSCB] L4Linux + IPC
by Oskar Senft 03 May '06

03 May '06

Hi all! We are using different Deamons running in L4Linux providing IPC services to other L4 task. With the most current DROPS CVS checkout, the L4Linux user processes freeze completely, as soon as an IPC call is executed which causes the process to sleep (eg. DICE IPC server loop). The L4Linux kernel seems to run, as it answers Ethernet/IP "ping" requests. A connection to a running SSH daemon no longer is possible and active SSH connection freeze, too. => Only L4Linux userland processes are frozen ?!? This did not happen with other version of L4Linux (eg. from January) and does not depend on the program we run in L4Linux - it happens with different applications that provide IPC services. Is this a problem with our settings for L4Env / L4Linux? Or could it be a bug in L4Linux? Do you have a test program that should run? Regards Oskar.
