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...
