This is the OpenCores OpenRISC 1200 support for QEMU. Full implementation of the system-model and linux-user-model support.
OpenRISC 1200 is a OpenCores open source CPU, its architecture manual can be find at http://opencores.org/svnget,or1k?file=/trunk/docs/openrisc_arch.pdf --- Thank you all for your very helpful comments. If I made something wrong, please give me more comments, I'm afraid I did not catch you, made v3 not good enough. --- Signed-off-by: Jia Liu <pro...@gmail.com> --- Version History: V3: Addressed Stefan and Andreas's review comments: - use QEMU and OpenRISC's official name. Addressed Andreas's review comments: - reimplement cpu QOM. - combine target stubs and QOM implement. - use new commit message and subject. Addressed Max's review comments: - handle div zero exception. - reimplement float point instructions. - fix l.mac*, l.mul*, and more. V2: Addressed Malc, Weiren, Andreas and Blue's review comments: - reimplement cpu QOM. Addressed Andreas's review comments: - reimplement machine. - rewrite the Copyright Notice using better format. Addressed Blue and Weiren's review comments: - compiling with AREG0 and remove global env, no dyngen-exe longer. Addressed Max, Blue and Weiren's review comments: - handle div zero exception. - handle illegal instruction. Addressed Blue's review comments: - separate do_interrupt into intrpt.c form intrpt_helper.c. - add QEMU_NORETURN to raise_exception. - reimplement float instrutions. - fix type of linux syscall and termbits. - reimplement sim board. - use the LGPL web URL in Copyright Notice. - reimplemt branch instructions. - split taregt stubs, QOM and machine. V1: - add QEMU OpenRISC support. - well tested on x64 machine, and final tested x86 machine.
