Suggest adding port: linux/arm64 to Go Dashboard (http://build.golang.org)

[Wei....@arm.com]

Hi,

As ARM 64-bit chips make their way into servers, more and more Golang built software start to support port of linux/arm64. E.g., docker has supported building and testing on arm64. But users may encounter various failures when they build docker from source for arm64 platform with various go versions. I know that there are many causes for these failures and it will be an incremental process to improve arm64 port. So I suggest adding port: linux/arm64 to Go Dashboard (http://build.golang.org) so that we can find these failures as early as possible.

We had arm64 builders until the other day when our Linaro hosts died. They can be rebuilt on a new host I'm told. 

But packet.net also offered us some of their 96 core arm64 servers. I have them halfway set up.

They might be up today, depending on distractions.

Filed golang.org/issue/19929 (builder is gone) and golang.org/issue/19930 (dead builder looks like we never even bothered to have a builder).

We have arm64 builders again. (And a lot of them)

[Wei....@arm.com]

thanks for the quick response!

You just got lucky. The work was already underway. :-)

Considering that linux/arm is already the first class port, have you considered also adding linux/arm64 to the first class ports?

[Brad Fitzpatrick]

If by "first class" you mean downloads, then see https://github.com/golang/go/issues/19082

Good to know that go1.9 is going to provide official binaries for arm64 platform.

According to porting policy (https://github.com/golang/go/wiki/PortingPolicy),  linux/arm64 port still lacks following two properties for becoming "first class"

1. Broken builds block releases

2. Installation is documented at http://golang.org/doc/install

Is there anything we can do to help the port graduate to "first class"?

Does that mean we can get arm64 trybots soon? That'd be nice.

Cheers,

Both 4K and 64K page size?

Thanks,
