-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 FOSDEM 2014 - CfP: Microkernels / Component-based OSes devroom Fellow Operating System Hackers, built on the success of the microkernel devroom in the last years, FOSDEM 2014 [1] will host a devroom for developers of open-source microkernel- and component-based operating systems. The devroom is scheduled for Sunday, February 2nd, 2014. We are looking for talks in all areas related to microkernels and component-based operating systems. Possible subjects include, but are not limited to: - introduction of a specific OS or framework, - design of subsystems and general architecture of an OS, - hardware support, - success stories, experiences and lessons learned, - security and robustness, - improving the toolchain, - maintainance and testing, - higher-level languages for OS implementation, - community building. To submit a talk, please create an account at the conference's submission system [2] and select the devroom as the talk's track. Should there be any problems, please send a mail to the devroom mailing list [3]. In your submission, be sure to include: - Title and approximate length of the talk (in the General tab), - the correct track (also in the General tab), - a short abstract (in the Description tab).

can not get ipc error
by yuqing wang 08 Oct '13

08 Oct '13

Hi I used launchpad to start a hello_client and hello_server.I closed hello_server and expected the call from hello_client could cause an ipc error ,because the target is not exist . I modify the l4_ipc_call function in file ipc-l42-gcc-nopic.h L4_INLINE l4_msgtag_t l4_ipc_call(l4_cap_idx_t dest, l4_utcb_t *u, l4_msgtag_t snd_tag, l4_timeout_t timeout) L4_NOTHROW { l4_umword_t dummy1, dummy2, dummy3; l4_msgtag_t rtag; (void)u; __asm__ __volatile__ (L4_ENTER_KERNEL : "=d" (dummy3), "=D" (dummy1), "=c" (timeout), "=S" (dummy2), "=a" (rtag.raw) : "S" (0), "c" (timeout), "d" (dest | L4_SYSF_CALL), "a" (snd_tag.raw) : "memory", "cc" L4S_PIC_CLOBBER ); // add by wyq int ipc_error = l4_ipc_error(rtag,u); if(ipc_error==L4_IPC_ENOT_EXISTENT ||ipc_error==L4_IPC_RECANCELED) { outstring("Ipc not exist or canceled "); } // end return rtag; } outstring is defined in <l4/sys/kdebug.h>,i am sure it can be used here. I can not get the output and i don't know why. Thanks & Regards

Fosdem'14

Hello, my dear friends. I am sorry if you receive multiple copies of this message (but I know, most of you will receive copies), but mailing list from uKernel dev room at FOSDEM'13 was destroyed (https://lists.fosdem.org/listinfo). Time rolls on, a FOSDEM'14 is not too far and now it is good time to submit a "uKernel and component based os" dev room. Who would like to organize dev room in this year? I would be proud to make this, but I heard someone from TUD would like to organize Dev room in this year. -- Sartakov A. Vasily sartakov@...104...

Hello World config
by Rudolf Weber 29 Sep '13

29 Sep '13

Hello, I'm using the public git version, the last commit is 3d5f77599fbdca8ae089f36e93b5ecd778ab5b3b . I forged the hello tutorial, but my version didn't run, nor the hello_tutorial itself. There was two errors: 1) the Service "CAP" was not found , first the service "LOG" was not found. 2) The server was not found. In the default route must be <any-service> <parent/> <any-child/> </any-service> or an specific route After some research in the run scripts, I found this following config: <config verbose="yes"> <parent-provides> <service name="ROM"/> <service name="RAM"/> <service name="IRQ"/> <service name="IO_MEM"/> <service name="IO_PORT"/> <service name="CAP"/> <service name="PD"/> <service name="RM"/> <service name="CPU"/> <service name="LOG"/> <service name="SIGNAL"/> </parent-provides> <default-route> <any-service> <parent/> <any-child/> </any-service> </default-route> <start name="timer"> <resource name="RAM" quantum="1M"/> <provides><service name="Timer"/></provides> <route><any-service><parent/></any-service></route> </start> <start name="hallo_server"> <resource name="RAM" quantum="1M"/> <provides><service name="Hallo"/></provides> </start> <start name="hallo_client"> <resource name="RAM" quantum="1M"/> </start> </config> It was successfully tested on Linux and foc (with qemu) Does the <parent-provides>-Section need to be compelete ? Does a Child can read out all services provided by its parent and all brothers wfrom which it is allowed to access services ?

Recent changes in genodelabs/master
by Norman Feske 26 Sep '13

26 Sep '13

Hello, hereby, I'd like to give a heads-up about some changes that recently hit the genodelabs/master branch. Some of them impose minor API changes. Others might just be interesting to look at. C++11 is now enabled by default. The implementation of the convenience function for accessing the process configuration ('Genode::config()') was moved to a library named 'config'. This avoids a possible ambiguity when creating a singleton instance of the 'Config' object. Furthermore, the 'config()' semantics have slightly changed. Earlier versions reflected errors while obtaining the configuration to the application via exceptions ('Xml_node::Invalid_syntax', 'Rom_connection::Rom_connection_failed'). So each program had to handle those. The new version responds to such failures by printing a diagnostic message and handing out an empty '<config/>' node to the application. There is a new utility for dispatching signals in the context of an RPC entrypoint (located at 'os/include/os/signal_rpc_dispatcher.h'). It allows an easy serialization of signal handlers and RPC functions at the server side. To avoid code duplications across current server implementations, there is a new library called 'server', which performs the steps that are similar for typical servers. The interface is located at 'os/include/os/server.h'. The implementation can be found at 'os/src/lib/server/server.cc'. This library implements the 'main' function of the server and executes the actual server-specific initialization code in the context of the server's entrypoint ('construct()'). The 'construct' function gets a reference to an 'Entrypoint' as argument. In contrast to a normal 'Rpc_entrypoint' the new 'Entrypoint' can serve both signal handlers and RPC functions. This eliminates the need to manually synchronize signal handlers (that were typically be called from the context of the main thread) and RPC functions. The nitpicker GUI server has been reworked to use the server library. Thereby the code has become much more robust. At the same time, nitpicker has become able to respond to configuration changes at runtime. If you like to have a look: 'os/src/server/nitpicker/main.cc' The convenience functions at 'os/include/os/session_policy.h' to parse session policies were slightly changed. The old version of 'Session_policy' took a session-argument string as argument. However, merely the session label was actually used to select a policy. The new version introduces a new 'Session_label' type that extracts the session label from the session arguments. The new 'Session_policy' takes a 'Session_label' as argument.
