@LolyRoP @ed_maste What revision is that? I don't remember ever seeing that code in the arm64 param.h & I wrote most of it.

15 years ago tomorrow I created this account so today I did the same on Mastodon at https://t.co/fScR4PDhbs

@bexcran If it's the recent snapshot it's missing the vmbus drivers it needs. The next snapshot should have them, however the driver currently hangs when passing messages between the host and guest.

[Andrew @zxombie]

@allanjude @bexcran It should boot under Hyper-V when we figure out why vmbus messages aren't working correctly.

Spent some time yesterday imporing improved arm64 string functions into the FreeBSD kernel. Saw a 14% improvement in system & 9% real time for buildkernel on some HW. (Thanks @freebsdfndation & @AmpereComputing)

Use the cached dc zva length in arm64 memset

On boot we cache the length the 'dc zva' instruction will zero. Use
this in the memset function to decide when to use it. As the ...

@avantekcomputer @AmpereComputing @freebsdfndation I'm sure @freebsdfndation would be happy with a donation of an AltraMax server

[Andrew @zxombie]

160 cores should be enough? (Thanks to @AmpereComputing for getting an Altra to @freebsdfndation for us to test #FreeBSD)

[Andrew @zxombie]

@MeezPower @AmpereComputing @freebsdfndation It's building packages so I would want it to be busy

[Andrew @zxombie]

@Sweordbora I'm not that far yet, I keep rebooting to test improvements to the cache handling code.

[Andrew @zxombie]

Poudriere seems to be happy

@FreeBSDHelp @haerwu @DrewGallatin @markjdb2 From memory it was an issue where only half a page would be loaded from disk because of assumptions in the VM or FS code. It would need to be fixed before adding 64k page support as userspace would be broken.

[Andrew @zxombie]

@haerwu @DrewGallatin @FreeBSDHelp @markjdb2 I would also like to finish removing a static PAGE_SIZE from userspace before dusting the 64k support off

[Andrew @zxombie]

@haerwu @DrewGallatin @FreeBSDHelp @markjdb2 I have patches, but some parts of the kernel don't like it when pages get that large

Can confirm, was hot.

I’d roll my eyes in Australian but I’ve lived in London I know how bad it was in the low 30s so 40 is going to be awful.
