[loongson-dev] Re: ioctl(fd, ASHMEM_SET_SIZE, size) failed
hi, zhangfx thank you for your tips. By implementing a compact_ioctl function, I have succeed solved this problem(At least not reporting error if not solved it).

currently, I don't have 32bit gcc on hand, can you upload an 32bit version to the community if convenient, thank you !

Currently, the init program runs into the for deadline, but the eth is down, so init can not communicate with other process, so the for statement loops some time and the machine reboot!

Re: [loongson-dev] Re: ioctl(fd, ASHMEM_SET_SIZE, size) failed
The init should then launch the shell and others following the instructions from /init.rc. Anyway, that's not a longson-specific issue anymore ^_^ . Fiddle with your android and be happy ^_^ . 在 2011年12月13日 上午12:30，李晖 写道： > Currently, the init program runs into the for deadline, but the eth is > down, so init can not communicate with other process, so the for > statement loops some time and the machine reboot! > > On 12月12日, 下午2时59分, Zhen Xin wrote: >> Android needs the kernel be 32bit. >> >> 在 2011年12月11日 下午11:37，zhangfx 写道： >> >> >> >> >> >> >> >> >> >> > If you are using 64bit kernel,you need to handle the 32 bit ioctl.
