On the other hand, it seems that the current qemu-aarch64 supports only the maximum length of 2048 bits as the SVE register size. I am writing an assembler program for a CPU that is compliant with ARMv8-A + SVE and has a 512-bit SVE register, but when this is run with qemu-user-aarch64, a 2048-bit load / store instruction is executed This causes a segmentation fault. Shouldn't qeum-user-aarch64 have an option to specify the SVE register size? - -This is already managed by a cpu property. - -0df9142d27d5 ("target/arm/cpu64: max cpu: Introduce sve<N> properties") - -See docs/arm-cpu-features.rst - -Try "-cpu max,sve512=on". - - - -Note also that the vector length in SVE is not fixed -- you should be writing your guest code to support arbitrary vector lengths, because otherwise it will not run on all SVE-supporting CPUs. - - -Thank you for your kind advice. I'll try it. - |
