This patchset is v6 of the "preparation patchset" that started off with Alex, was passed to John Rigby and now to me. *** I plan to commit these patches (except the configs *** patches which actually enable the aarch64 targets) *** to target-arm.next unless there are issues raised in *** review of this series. We've got 1.6 out of the door now, and I expect the aarch64-linux-user code to arrive before 1.7, so I think the time is now right to get these preparatory patches into master. If there's anything you want to see addressed before then, please mention it. (My apologies if I've failed to notice any review comments on earlier versions of the series; if so, please flag that up.) With these patches: * new target aarch64-linux-user, which will run but SIGILL on all instructions * new target aarch64-softmmu, which will run all the 32 bit CPUs and board models; however there is no 64 bit CPU defined so it's a bit pointless except as a demonstration that we haven't broken the 32 bit code. Available in git at: git://git.linaro.org/people/pmaydell/qemu-arm.git aarch64 Changes since v5: * created a QOM type AArch64CPU -- all 64 bit capable CPUs will be subtypes of this. This means we can handle things like gdb set/get functions and the cpu state dump function by just setting the class function pointers here, which is a nice little cleanup. * fixed bogus type for sigaltstack ss_flags field * added endianness handling for vfp regs in signal struct * dropped the aarch64-fpu.xml (it was unused). I have a prototype patch which adds it back and actually registers it together with some fp reg load/save functions, but I don't currently have any way of testing it so it's not in this patchset. * generalised the workaround for the guest glibc barfing if the kernel version reports as <3.8.0 and integrated it better with the existing "lie to guest about version" code * aarch64-linux-user only provides 64 bit capable CPUs Changes v4 to v5: * various bits of cleanup for style and other minor things * a little shuffling and splitting of patches * made the 32 bit CPUs work in aarch64-softmmu * given aarch64 its own cpu_loop() in linux-user/main.c * made sure NWFPE doesn't sneak into aarch64-linux-user * let aarch64 have a nearly clean slate for tb_flags Note that in general the 'signed-off-by:' lines from people other than me should be taken to indicate credit/authorship rather than "I'm happy with this patchset", given that I've changed the patches as they passed through my hands. Individual patches have a summary of my changes in the commit.
