Base capabilities
by Daniel Waddington 22 Mar '11

22 Mar '11

Hi, I'm trying to put in some temporary feature in Genode to set the affinity of threads. In Genode the scheduler capability (L4_BASE_SCHEDULER_CAP) doesn't seem to be passed from the core to the children. Is there any obvious way to do this with the existing Genode implementation - we can hack up a solution but I wanted to check first. Thanks Daniel

Using Fiasco L4re APIs
by Daniel Waddington 17 Mar '11

17 Mar '11

Hi, I'd like to be able to use the native Fiasco.OC L4re APIs (actually to set thread affinity) from within my Genode application. Its not clear to me how to set up the target.mk to do such things. Any advice? Daniel

Use of malloc primitives in Genode
by Amadeo Cuadrado 16 Mar '11

16 Mar '11

Hello, When I try to build the app below in Genode, the following linking error happens: main.o: In function `main': .../main.cc:6: undefined reference to `malloc(unsigned int)' .../main.cc:8: undefined reference to `free(void*)' What am I missing here? Thanks! Amadeo :::::::::::::: main.cc :::::::::::::: #include <stdlib.h> #define N 10 int main(void) { int *v = (int *) malloc(N*sizeof(int)); for (int i=0; i<N; i++) v[i] = i; free(v); } :::::::::::::: target.mk :::::::::::::: TARGET = foo SRC_CC = main.cc LIBS = cxx env mini_c

LDSO main()
by Sam Kerr 15 Mar '11

15 Mar '11

Hello all, I am trying to do some work with dynamic linking and saw there is an LDSO folder with a main() function. I would like to try running this on top of Pistachio. However, I cannot get the main() function to run. I have tried just including the module in the grub.conf file to no avail. Does anyone have some guidance on how to boot the LDSO test function? -Sam Kerr

Problems with socket()
by Александр Домо 15 Mar '11

15 Mar '11

Hello! I'm writing a network application using libc, lwip, libc_lwip, and libc_lwip_nic_dhcp. But when I call socket(SOCK_STREAM), it hangs somewhere in lwip_socket(). Maybe it has something to do with the lwip tcp thread, but I'm not sure. What else should I check for? Thanks.

Hi, Is Genode+Fiasco.OC x86_64 known not to work? After various fiddling about with include files, and -m64 flags I got as far as the following.. Thanks Daniel Program drivers/framebuffer/vesa/vesa_drv COMPILE decode.o COMPILE fpu.o COMPILE framebuffer.o COMPILE hw_emul.o COMPILE ifx86emu.o COMPILE main.o COMPILE ops.o COMPILE ops2.o COMPILE prim_ops.o COMPILE sys.o LINK vesa_drv ifx86emu.o: In function `unsigned int inx<unsigned int>(unsigned short)': ifx86emu.cc:(.text+0x4c8): undefined reference to `bool hw_emul_handle_port_read<unsigned int>(unsigned short, unsigned int*)' ifx86emu.o: In function `void outx<unsigned int>(unsigned short, unsigned int)': ifx86emu.cc:(.text+0x649): undefined reference to `bool hw_emul_handle_port_write<unsigned int>(unsigned short, unsigned int)' collect2: ld returned 1 exit status make[2]: *** [vesa_drv] Error 1 make[1]: *** [vesa_drv.prg] Error 2 make: *** [gen_deps_and_build_targets] Error 2

Equivalent to ucontext APIs
by Daniel Waddington 08 Mar '11

08 Mar '11

Hi, I want to perform user-level scheduling in Genode. Previously we used the POSIX ucontext APIs to save the thread's state, create a new context, and swap between contexts. Before I try to put the equivalent in place in Genode, I am wondering if there are any existing facilities to do this sort of thing in user-space. Also any advice on approach is welcome. Thanks Daniel
