[aarch64] Change huge page config on aarch64 machine on o3

Updated about 5 years ago.
Description
Current huge pages memory is ok for 10 workers, but not enough for 16 workers. And we have enabled 6 additional workers for testing.
So, we need to:
- Increase the size to 64 GB
- Change page size from 2MB to 1GB
- Project changed from openQA Project to openQA Infrastructure
- Status changed from New to In Progress
- Assignee set to mkittler
- Status changed from In Progress to Resolved
I changed the following configuration:
- Add
default_hugepagesz=1G hugepagesz=1G hugepages=64 to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub.
- Set
vm.nr_hugepages from 14336 to 64 in /etc/sysctl.conf in accordance with boot parameter set in 1..
- Execute
grub2-mkconfig -o /boot/grub2/grub.cfg transactional-update grub.cfg.
Seems like it worked:
cat /proc/cmdline
BOOT_IMAGE=/boot/Image-4.12.14-lp150.12.58-default root=UUID=25944857-5dd8-410b-8eb3-ce80dcd6b21a console=ttyAMA0,115200 splash=silent quiet showopts nospec spectre_v2=off pti=off kpti=off default_hugepagesz=1G hugepagesz=1G hugepages=64
grep Huge /proc/meminfo
AnonHugePages: 10240 kB
ShmemHugePages: 0 kB
HugePages_Total: 64
HugePages_Free: 64
HugePages_Rsvd: 0
HugePages_Surp: 0
Hugepagesize: 1048576 kB
So we now use 64 GiB of 125 GiB for hugepages.
