i also commited a kernel for the raspberry pi 3 in
/sys/src/9/bcm64. it uses all the drivers from richard
millers bcm kernel. tho there are still some issues with
usb at startup and multicore which i have worked arround
by having the secondary cores join the scheduler later.

its just control transfers that randomly fail with
i/o error on startup.

usb ethernet and mouse/keyboard work just fine with
multiple cores afterwards. not figured out why yet.

there are still tons of low hanging fruits for improvement.

my libmach disassembler doesnt know about simd instructions
yet.

i do not even have assembly routines for memmove and memcpy
in libc yet. still games/doom works.

You also need to rebuild pcc on the host platform before doing the
arm64 build.

This is really nice. What ARM64 board did you use to develop/test this?

Thanks,

small correction in the last announcement.
i ment /arm64 not /amd64 ...

and i forgot to mention the obvious that to compile code
for arm64, you need to have a compiler. so lets make one:

for(i in /sys/src/cmd/7[acl]){cd $i && mk install}
