Description Vincent Milum Jr 2020-10-27 05:14:56 UTC
The Galera26 port for compiling on ARM64/Aarch64 is only missing a single function call to make it work.

I pulled this out of sys/x86/include/endian.h

#define	__bswap64_gen(x)		\
	(((__uint64_t)__bswap32((x) & 0xffffffff) << 32) | __bswap32((x) >> 32))

static __inline __uint64_t __bswap64_var(__uint64_t _x)
	return (__bswap64_gen(_x));

After this, Galera26 compiles just fine on ARM.

Next up, the MariaDB ports need a small fix as well. They're missing the wasrep_ shell scripts due to the following in databases/mariadb10x-sever/Makefile

.if ${ARCH} != amd64
PLIST_SUB+= WSREP="@comment "

With this, I now have a Galera cluster up and running across 3 ARM VMs.

Please submit Galera fix upstream, https://github.com/codership/galera seems to be upstream repo.
Best regards

In this particular case, the "upstream" I think is actually FreeBSD itself. The missing function is defined in the FreeBSD source tree for i386, amd64, and other platforms, but missing for arm and arm64. This was noted in my initial report showing that I pulled in the copy from i386, which made this port functional in arm64.

Can you try this patch?

can you open another pr for mariadb please?

Applied the patch, compiled cleanly, and am now running it on my test aarch64 cluster.

As a side note, did a rolling upgrade from my 26.4.5 patch to your 26.4.6 patch without taking the cluster offline. All worked exactly as expected. :)
Comment 7 Vincent Milum Jr 2020-10-31 16:45:41 UTC
While I think its good to try to get upstream support, I'm going to once again reiterate that the missing functionality (64-bit byte swapping) is something that should be provided by the main FreeBSD source tree. I'm running into issues with other ports now that have similar endian/byte swapping functions missing. 

Please compare these two files



Correcting this in the FreeBSD source tree itself for arm64, getting its endian support up to date with x86 targets, will enable a number of ports beyond just databases/galera26 to start working.

Do you have a phabricator account? Can you provide a patch and add the aarch64 group?

Do you have a list of affected ports? We'll have to patch them anyway to support FreeBSD < 13.x
