Re: Genode Hack'n Hike 2013
by Norman Feske 23 Mar '15

23 Mar '15

Hello everyone, the date for this year's Genode Hack'n Hike held during 11-16 of September is approaching. Genode's developers will spend those days in the beautiful scenery of the Bohemian Switzerland, relaxing, hiking, and hacking on fun side projects. The Hack'n Hike will be the perfect setting for getting involved with the community, catching up, or just hanging out with the Genode crowd. There is still room for more participants. Genode Labs sponsors the event. So your participation/accommodation is free. If you like to join in, please get in touch by writing to hacknhike@...1... or commenting on https://github.com/genodelabs/genode/issues/793.

Re: Porting on i.MX6
by Aditya Kousik 23 Dec '13

23 Dec '13

Hello Firstly, thank you for patiently replying to our queries and debugging issues so far. We're trying to port Genode onto an i.MX6, which we've realised is no easy task. Our initial approach to this was to tweak existing i.Mx53 files and make corresponding changes (arm cortex a9, created imx6 related folders in include). As pointed out to us by Stefan, this was completely off track as the memory layout may be mixed up (or many more issues). Here's a brief reboot of our attempt: 1. edit create_builddir to add a rule for imx6 board and added build.conf.hw_imx6 in builddir folder. 2. modify board_base.h in base/include/platform/imx6/drivers and fill with addresses by referring to the imx6 reference manual. (We also added CORTEX_A9_CLOCK and private memory base) 3. read through the Makefile and added spec-hw_imx6 and spec-platform_imx6 respectively. 4. created imx6 folder with files in os/include/platform/imx6 as well. (All with imx53 as reference) Make: Since the drivers for imx6 would take a long time to code, we are NOT running demo.run. We tried to build hello.run (without building drivers/timer) according the instructions given in your site. We're getting the following error: Program core/imx6/core COMPILE _main.o ASSEMBLE boot_modules.o COMPILE console.o COMPILE context_area.o COMPILE cpu_session_component.o COMPILE cpu_session_support.o ASSEMBLE crt0.o COMPILE dataspace_component.o COMPILE dump_alloc.o COMPILE io_mem_session_component.o COMPILE io_mem_session_support.o COMPILE irq_session_component.o COMPILE kernel.o COMPILE kernel_support.o COMPILE main.o make[3]: *** No rule to make target `mode_transition.o', needed by `core'.

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.

Using C++11 by default
by Norman Feske 17 Sep '13

17 Sep '13

Hello, I would like to go with the times and switch Genode to use C++11 by default. This will enable us to solve a number of problems in a more elegant way, e.g., by using variadic templates for the RPC framework, we can possibly get rid of the current limit of the number of RPC functions supported by the 'GENODE_RPC_INTEFACE' declarations. Are there any objections from Genode users? For example, is anyone of you still using a custom tool chain that does not support C++11? If no one disagrees, I would go forward and add '-std=gnu++11' as default argument to g++. Regards Norman -- Dr.-Ing.
