arm64

I was wondering if there is a way to exit from qemu from within the guest system in the aarch64 version. For instance the x86 has the isa-debug-exit device which is used for this purpose. Any ideas? Cheers The general answer to this question is "do whatever you would do on the real hardware to cause a power-off". The details of this depend on which machine QEMU is emulating. For the aarch64 "virt" board, you can use the emulated PSCI firmware interface to request a powerdown using the SYSTEM_OFF function. The PSCI API documentation is here: http://infocenter.arm.com/help/topic/com.arm.doc

I'm trying to compile a Android Kernel from source and I believe I have downloaded all the right packages to do it but for some reason I get this error ---> arm-linux-androideabi-gcc: error: unrecognized command line option '-mgeneral-regs-only' /home/livlogik/android/kernel/H901BK_L_Kernel/./Kbuild:35: recipe for target 'kernel/bounds.s' failed make[1]: *** [kernel/bounds.s] Error 1 Makefile:858: recipe for target 'prepare0' failed make: *** [prepare0] Error 2 I have the latest NDK and I'm using Ubuntu 15.10 64bit if this helps. Here is where I have the NDK and kernel ---> NDK ---- /home

I've got some assembly functions I've ported to 64-bit ARM, and they work fine on Android, but when I tried to compile the same files in Xcode, I discovered that clang uses a different syntax (different from the official ARM documentation). I've found some scripts which convert a source file from one format to the other, but this is not the ideal solution (and it seems these scripts don't work when the source files contain preprocessor defines). Can I simply use gas in Xcode, or configure clang to accept the gas syntax? If not, where is the clang assembler documentation? UPDATE - September

The aarch64 architecture doesn't have instructions for multiple store and load, i.e. there are no equivalents of stm and ldm from armv7 arch. Instead you must use the stp and ldp instructions for store and loading pairs of registers. Accroding to the ARM reference manual: http://www.element14.com/community/servlet/JiveServlet/previewBody/41836-102-1-229511/ARM.Reference_Manual.pdf There are no multiple register LDM, STM, PUSH and POP instructions, but load-store of a non-> contiguous pair of registers is available. My question is, what does non-contiguous mean or refer to here? My instant

It took some time for me to compile LibiCal for arm64 and x86_64 architecture for iOS(device and simulator). Thought it may be useful for others. Here is the steps I followed to compile LibiCal-1.0. I have taken code from below link Compiling libical and modified a bit to suit for Xcode 5.1 1) download LibiCal from below URL http://sourceforge.net/projects/freeassociation/ Untar and get into libCal-1.0 folder. Then run ./bootstrap (Need to download make tools from http://www.jattcode.com/installing-autoconf-automake-libtool-on-mac-osx-mountain-lion/ ) Use below script #!/bin/sh # SEE: http:/
