Zhe Weng 3d5eae2497 arch/arm64: Enable FPU for qemu-armv8a:netnsh_smp and netnsh_smp_hv ... When reading https://github.com/apache/nuttx-apps/pull/1793, I found a previous problem https://github.com/apache/nuttx-apps/pull/1454#discussion_r1045718067 now still exists on current master (inf in iperf bandwidth). By step-by-step debugging, I found a value of 1000000.0 stored in register d8 is overwritten as 0 after context switch, then fdiv results in inf because of divided by 0. Finally I found that ARCH_FPU is not enabled while compiler is using FPU, and may lose values in floating-point registers. Signed-off-by: Zhe Weng <wengzhe@xiaomi.com>		2023-07-12 10:04:13 -03:00
