I bought 2020 MacBook Air in early 2021 since I was waiting for the catch-up of the software adaptation to the M1 chip. Here, I would like to talk about my experience with M1 MacBook AIr. I put some links below for your reference.

If you are intested in the general experience of M1 MacBook Air, there are a lot of YouTube videos you can checkout out. Overall, I am satisfied with this solution, and I have already integrate my MacBook Air into my daily work pipeline. Both methods run blazingly fast on my 2020 M1 MacBook Air without noise and obvious heat.

There are two ways you can use ROS and ubuntu on Apple M1 chip: Virtual Machines and Docker. *R(VIRTIO_MMIO_DRIVER_DESC_LOW) = (uint64)disk.In this post, I will introduce the setup procedure of Ubuntu and ROS on the platform based on Apple Silicon M1 chip. MAXVA is actually one bit less than the max allowed by // Sv39, to avoid having to sign-extend virtual addresses // that have the high bit set. # define PA2PTE (pa ) ( ( ( (uint64 )pa ) > 12 ) > 10 ) > PXSHIFT (level ) ) & PXMASK ) // one beyond the highest possible virtual address. void start ( ) # define PGSIZE 4096 // bytes per page # define PGSHIFT 12 // bits of offset within a page # define PGROUNDUP (sz ) ( ( (sz ) +PGSIZE - 1 ) & ~ (PGSIZE - 1 ) ) # define PGROUNDDOWN (a ) ( ( (a ) ) & ~ (PGSIZE - 1 ) ) # define PTE_V ( 1L user can access // shift a physical address to the right place for a PTE. extern void timervec ( ) // entry.S jumps here in machine mode on stack0. Uint64 mscratch0 // assembly code in kernelvec.S for machine-mode timer interrupt. _attribute_ ( ( aligned ( 16 ) ) ) char stack0 // scratch area for timer interrupt, one per CPU. 修改方案见链接： Fix boot on newer qemu #62 2.1.1 kernel/start.c 修改为⬇️ # include 'types.h' # include 'param.h' # include 'memlayout.h' # include 'riscv.h' # include 'defs.h' void main ( ) void timerinit ( ) static void pmpinit ( ) // entry.S needs one stack per CPU. 我这里主要是解决make qemu之后，xv6-riscv可以运行，但是 xv6-labs-2020系统hang在此处⬇️的bug qemu-system-riscv64 -machine virt -bios none -kernel kernel/kernel -m 128M -smp 3 -nographic -global virtio-mmio.force-legacy =false -drive file =fs.img,if =none,format =raw,id =x0 -device virtio-blk-device,drive =x0,bus =virtio-mmio-bus.0
