arm-x19 support? #4

Closed brunoga closed 4 years ago

brunoga commented 4 years ago

I have an old NAS (QNAP TS-219P) with a Marvell CPU (arm-x19) that I would love to get tailscale running on. Any chance you could support this (assuming tailscale itself would compile for this platform, that is)?

It seems that it would be possible to compile tailscale to different arm architecture versions (https://github.com/golang/go/wiki/GoArm). However, I am not sure which arm architecture versions maps to which QNAP arm versions. I assume that QNAP arm-x19 corresponds to armv7, but I am not sure.

Would it be possible to give the output of cat /proc/cpuinfo on your NAS?

Here it is:

cat /proc/cpuinfo

Processor name : Feroceon 88F6281 rev 1 (v5l) @ 1.2 GHz BogoMIPS : 1196.85 Features : swp half thumb fastmult edsp CPU implementer : 0x56 CPU architecture: 5TE CPU variant : 0x2 CPU part : 0x131 CPU revision : 1

Hardware : Feroceon-KW ARM Revision : 0000 Serial : 0000000000000000

It is actually ARMv5. So GOARM=5 should do the trick. Is tailscale pure Go? Otherwise a C toolchain for arm v5 should be needed.

Thanks for looking into this. It would be great to have it working on this NAS.

FYI, I got it to work by simply replacing all occurrences of -x41 to -x19 and forcibly setting GOARM=5.

I guess what you might want to do is to add a -19 qbuild and them compile one other arm version with GOARM=5 set. You will need to change your naming strategy (maybe add GOARCH and GOARM to the name instead of only GOARCH when arch is ARM?

@brunoga Thank you! Your solution works for the old HS-210 as well.

ivokub commented 4 years ago

Thanks for the feedback and confirming that GOARM=5 works on your QNAP.

I created a pull request. It looks like ARM-x19 package compiles fine. I am merging the pull request and closing the issue for now. If the package does not install or work nicely, then please reopen.
