Client/Server Application, Noux and the rest
by unknown＠example.com 22 Oct '15

22 Oct '15

Hey Genodians, I am facing a problem with the Server/Client Application. But first a short summary, what happend: With the help from Johannes I am able to use Genode on the ZedBoard. So the hello_tutorial is working fine and after that I am now trying to build my own Server/Client Application. Here is the output from the boot up: kernel initialized Genode 15.05 int main(): --- create local services --- int main(): --- start init --- int main(): transferred 502 MB to init int main(): --- init created, waiting for exit condition --- [init] parent provides [init] service "ROM" [init] service "RAM" [init] service "IRQ" [init] service "IO_MEM" [init] service "CAP" [init] service "PD" [init] service "RM" [init] service "CPU" [init] service "LOG" [init] service "SIGNAL" [init] child "timer" [init] RAM quota: 765952 [init] ELF binary: timer [init] priority: 0 [init] provides service Timer [init] child "own_server" [init] RAM quota: 33271808 [init] ELF binary: own_server [init] priority: 0 [init] provides service First_Service [init] provides service Second_Service [init] child "own_client" [init] RAM quota: 16494592 [init] ELF binary: own_client [init] priority: 0 [init] child "timer" announces service "Timer" init -> own_server -> own_server: undefined instruction at ip=3983cc init -> own_client -> own_client: undefined instruction at ip=3743cc My assumption on what is going wrong is the following: The server and the client needs to access the jitterentropy node at /dev/random and needs to write in the /tmp folder. Here is the part of the run file: set config { <config verbose="yes"> <parent-provides> <service name="ROM"/> <service name="RAM"/> <service name="IRQ"/> <service name="IO_MEM"/> <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> </start> <start name="own_server"> <resource name="RAM" quantum="32M"/> <provides> <service name="First_Service"/> <service name="Second_Service"/> </provides> <config> <libc> <vfs> <dir name="dev"> <jitterentropy name="random"/> </dir> <dir name="tmp"> <ram/> </dir> </vfs> </libc> </config> </start> <start name="own_client"> <resource name="RAM" quantum="16M"/> <config> <libc> <vfs> <dir name="dev"> <jitterentropy name="random"/> </dir> <dir name="tmp"> <ram/> </dir> </vfs> </libc> </config> </start> </config>} I have no initramfs and linux kernel included which could provide the path to the folders. So how do I provide the server and client to access the file/folder? Can I use the server/ram_fs or should I use the Noux Runtime Environment? Or is it something else? Thank you in advance. Jack

Hi All, Can we port and run a Linux program which includes Linux kernel header files such as linux/device.h using Noux runtime environment in Genode? Thank you in advance for your time. thanks and best regards, Kas

Hi everyone, I tried to make compile SEL4 + GENODE. However, I must admit that this is a fail from my side. The demo linux is compiling fine, but regarding sel4 I cannot make it work due to standard lib header missing. To make it happen, I simply followed the tutorial from Norman (step 1). I managed to make things work until make kernel command. After that I discovered that it was not executing the right kernel.mk file (there is one already delivered in latest sources), It compiles fine if I adapt a little bit CFLAGS. Then the issue comes when trying to test the make run/test that is failing differently than what is described in the tutorial. (In fact, it is supposed to work in the tutorial) It may be for sure a simple issue, but I don't really understand why I have this issue while compiling test and not the kernel... The issue is the following: error: no include path in which to search for stdint.h (and same for assert.h) Do you think you could help me to figure out this issue, and maybe document it in your web page ? Here is the trace below (I have a Ubuntu 14.04 LTS & x64 installation) *adg@...363...:~/dev/genode/genode/repos/base-sel4$ make run/test VERBOSE=* *test -f "/home/adg/dev/genode/genode/repos/base-sel4/run/test.run" || (echo "Error: No run script for test"; exit -1)* *~/dev/genode/genode/tool/run/run --genode-dir ~/dev/genode/genode \* * --name test \* * --specs "sel4 x86_32 x86 32bit" \* * --repositories "/home/adg/dev/genode/genode/repos/base-sel4 /home/adg/dev/genode/genode/repos/base" \* * --cross-dev-prefix "/usr/local/genode-gcc/bin/genode-x86-" \* * --qemu-args "" \* * \* * --include /home/adg/dev/genode/genode/repos/base-sel4/run/test.run* *including /home/adg/dev/genode/genode/repos/base-sel4/run/test.run* *building targets: test/sel4 * *spawn make test/sel4* *make[1]: Entering directory `/home/adg/dev/genode/genode/repos/base-sel4'* *checking library dependencies...* * Library platform* * Library syscall* * Library core_printf* * COMPILE core_printf.o* */usr/local/genode-gcc/bin/genode-x86-g++ -ffunction-sections -fno-strict-aliasing -nostdinc -g -march=i686 -m32 -O2 -MMD -MP -MT 'core_printf.o core_printf.d' -Wall -std=gnu++11 -I. -I/home/adg/dev/genode/genode/repos/base-sel4/src/base/console -I/home/adg/dev/genode/genode/repos/base-sel4/src/core/include -I/home/adg/dev/genode/genode/repos/base-sel4/src/base -I/home/adg/dev/genode/genode/repos/base/src/base/thread -I/home/adg/dev/genode/genode/repos/base-sel4/include -I/home/adg/dev/genode/genode/repos/base/include/spec/x86 -I/home/adg/dev/genode/genode/repos/base/include/spec/x86_32 -I/home/adg/dev/genode/genode/repos/base/include/spec/32bit -I/home/adg/dev/genode/genode/repos/base-sel4/include/sel4 -I/home/adg/dev/genode/genode/repos/base-sel4/include -I/home/adg/dev/genode/genode/repos/base/include -I/usr/local/genode-gcc/bin/../lib/gcc/x86_64-pc-elf/4.9.2/include -c /home/adg/dev/genode/genode/repos/base/src/base/console/core_printf.cc -o core_printf.o* *In file included from /home/adg/dev/genode/genode/repos/base-sel4/include/sel4/arch/types.h:14:0,* * from /home/adg/dev/genode/genode/repos/base-sel4/include/sel4/types.h:15,* * from /home/adg/dev/genode/genode/repos/base-sel4/include/sel4/arch/functions.h:14,* * from /home/adg/dev/genode/genode/repos/base-sel4/src/base/console/core_console.h:18,* * from /home/adg/dev/genode/genode/repos/base/src/base/console/core_printf.cc:23:* */usr/local/genode-gcc/bin/../lib/gcc/x86_64-pc-elf/4.9.2/include/stdint.h:9:26: error: no include path in which to search for stdint.h* * # include_next <stdint.h>* * ^* *In file included from /home/adg/dev/genode/genode/repos/base-sel4/include/sel4/types.h:16:0,* * from /home/adg/dev/genode/genode/repos/base-sel4/include/sel4/arch/functions.h:14,* * from /home/adg/dev/genode/genode/repos/base-sel4/src/base/console/core_console.h:18,* * from /home/adg/dev/genode/genode/repos/base/src/base/console/core_printf.cc:23:* */home/adg/dev/genode/genode/repos/base-sel4/include/sel4/types_gen.h:4:20: fatal error: assert.h: No such file or directory* * #include <assert.h>* * ^* *compilation terminated.* *make[3]: *** [core_printf.o] Error 1* *make[2]: *** [core_printf.lib] Error 2* *make[1]: *** [gen_deps_and_build_targets] Error 2* *make[1]: Leaving directory `/home/adg/dev/genode/genode/repos/base-sel4'* *Error: Genode build failed* *make: *** [run/test] Error 252* Thanks a lot in advance.

genode bare hardware on the odroids - howto?
by Suriyan Ramasami 19 Oct '15

19 Oct '15

Hello wonderful people! Greetings and thanks for the awesome work with genode. I have been trying to run genode on bare hardware on the odroids -> odroid-x2/odroid-xu for which I presume - they are already supported (the release notes mention them). What is missing is a step by step guide of building say, nested_init or a simpler printf application which shows some output when run from the uboot prompt. I tried following the instructions as mentioned in http://genode.org/documentation/platforms/hw (it generates an elf file, but then passing RUN_OPT="--target uboot" did not create the uImage file. Well, I did convert the elf to a bin file with objcopy and then converted that to an uImage file with mkimage. Am not sure if that is correct. What, I ask is, is there a step by step which will get me an UART output from genode on any of the supported odroid's using the latest genode code from git? Any pointers to such a doc would be immensely helpful to me as I would like to explore genode. Thanks in advance! Regards - Suriyan

AHCI Driver
by Harm de Vries 08 Oct '15

08 Oct '15

Hello everyone, The error message ``Device does not support native command queuing: abort'' is written repeatedly to the log when I try to read from a SATA disk using the AHCI driver. Is this driver only meant to work with a SATA disk that supports native command queuing (the HBA supports it)? While looking at the code of the driver to determine the cause of the error I noticed that: 1. In ahci.cc en main.cc the word `available' has been misspelt as 'avaiable'. 2. In ahci.h the bitfield that indicates support for native command queuing in the HBA seems to be misspelt as `Sncg'. There is also a function with the name `ncg' and this abbreviation is also used in the function `info'. 3. The struct `Identity' in ahci.h describes the structure of the result of an ATA command. Is there a reason why this struct and the corresponding function `identify_device' are not in the file `ata_driver.h'? Best regards, Harm

Porting Genode to the ZedBoard
by unknown＠example.com 07 Oct '15

07 Oct '15

Hello Genodians, I am trying to port Genode to the ZedBoard, but currently I am having some problems to get the UART online. My starting point is this mail: <http://sourceforge.net/p/genode/mailman/message/33222798/> and as a reference I use the Pandaboard, because it has also a Cortex A9. So is it right, that the board_base.h is in some way like a devicetree file? If this is the case, how can I add some other devices like Ethernet, OLED-Display or the FPGA? Is there some more documentation on how to port Genode to another hardware? To come back to the UART: I hope that I can use the PL011 driver, because the ZedBoard does not have the TL16C750 chip from the Pandaboard (the ZedBoard has a Ti TUSB1210 chip). So is this possible? I think I already have the right base addresses from the technical reference manual, but I am still not getting on how to set the clock and the interrupts. Looking forward to your replies.
