It does seem impossible to get VMWare Fusion demos anymore. Damn it, I needed that to test OpenBSD/arm64

Checking out -current via CVS is just kinda dreadful. I'm not thrilled on building this on a Pi either, but it's good to at least have a not entirely broken example either. I do wonder if it would be faster to check out elsewhere and rsync

I'm going to let the pi build OpenBSD-current overnight (hopefully it finishes by morning), and then probably do debugging tomorrow

Anyway, back home. Decided to get back to the OpenBSD/arm64 issues. I threw it on a Pi, and its not spinning which means its at least not a general platform issue.

I somehow managed to find a 2G cell phone network in 2024 …

As a New York City native, currently living in New Jersey, I should really visit the Statue of Liberty at some point in my life ...

@sayartyler its more "if New York is the World's Capital, then New Jersey is the World's Toxic Waste Dump".

It's also where the light at the end of the tunnel leads.

We proudly host more federal superfund sites per capita than any other place in the country by a wide margin.

As for me, I'm the child of third generation Italians, and a Cuban exile who was born in the United States.

Half of my culture got embargoed, and the other half has faded into English :/

I think the next step is to build the OpenBSD kernel singleprocessing and see if the gprof output gives more clues.

It's spending a lot of time dealing with VM related stuff, but after staring at the code for awhile, nothing is jumping out. Single core performance was a lot better though whcih makes me suspect this is a SMP issue.

Reading through gprof's manual, and reading OpenBSD source code to understand why its spinlocking.

If nothing else, it's helping getting the rust off on low level system programming.

Today was a very miserable day of adulting. I'm going to unwind for awhile, and then probably poke the OpenBSD kernel with a stick afterwards ...

TIL I learned you need to enable hyperthreading on OpenBSD by hand.

I get the security risk, but man, it would have helped to figure out why it was much slower than expected.

I wonder if the problem on MBP was due to the same factor.

@ncommander Apple Silicon doesn't have SMT so it's not precisely that. But there could certainly be other tunables that would help.

ncommander,
@ncommander@restless.systems avatar

@onekopaka Well I saw that it was doing the same TOP behavior only showing half the processors, which didn't quite register as why it was weird. But that's why I want to profile it

My OpenBSD maker is ready for the next stream.

ncommander,
@ncommander@restless.systems avatar

I'm confirming I can infact build OpenBSD normally before doing anything else.

Cause cross-compiling is def. not supported by the devs, but I'm not sitting through what I suspect will be a full day or more to compile on the MBP.

ncommander,
@ncommander@restless.systems avatar

Well typing "make" was not enough to build.

Plans for today flying out the window (which throws my entire week into chaos) so debating what I'm doing today.

At least I got the video finished this week \o/
