runtime: arm64 64k PAGE_SIZE compile all.bash testcase error. #11933

jefby · 2015-07-30T07:39:01Z

Hi,my arm64 kernel PAGE_SIZE is 64k,and i change the _PhyPagesize to 65536 in arch1_arm64.go file,and it can compile and run,but some test case prints error.

2.garbage_test error

2.garbage_test error

This is #9993

What hardware are you running on ?

jefby · 2015-07-30T09:19:06Z

@davecheney Cavium ARM64 board.

davecheney · 2015-07-30T09:21:15Z

Thanks. I was going to say you were out of physical memory (you probably
need at least 512mb per core), but on that system it is unlikely.

@jefby,

Please open a new issue for the TestIPv4MulticastListener error. It may be irrelevant to linux/arm64 port.

jefby · 2015-07-30T09:27:18Z

@davecheney But the real physical memeory is 64GB,i think every core has larger than 512MB.

davecheney · 2015-07-30T09:39:58Z

Thanks for confirming. In the past we have seen timeouts related to
swapping. This is not the case in your situation, please disregard my
previous suggestion.

Well, Cavium systems have very high CPU counts. How many cores do you have?

jefby · 2015-07-30T10:21:37Z

@mwhudson 48 cores

ianlancetaylor · 2015-07-30T15:23:20Z

It looks like you are reporting three different problems.

The error in TestFreeOSMemory looks like a real problem that needs to be addressed one way or another.

The other two errors are timeouts, one in sync/atomic, one in cmd/go. Can you please run "go -test.short sync/atomic cmd/go" to see if the problems are repeatable? It may just be that the timeouts are too short for your system. The cmd/go test in particular takes a long time to run.

The scavenger is currently disabled if _PhysPageSize > _PageSize. This is issue #9993. I actually don't understand why this test isn't failing on the dashboard for arm64 and ppc64x.

I actually don't understand why this test isn't failing on the dashboard for arm64 and ppc64x.

Oh, duh, it's skipped on arm64 and ppc64x. @jefby, you didn't mention what version you're running; it must be before commit 7a63ab1, since that increased the arm64 page size to 64k and disabled that test on arm64.

rsc · 2015-07-30T19:04:33Z

Please try Go 1.5 beta 3 and open new, separate issues for problems you find. The page size one is definitely fixed. Thanks.
