Does #FreeBSD #kernel support #livepatching yet? I see some discussions here and there on the Internet. But I cannot find out if after all these discussions, the feature has been added or not.

در حال تحقیق برای پیدا کردن یه #کرنل که هم #هک کردنش آسون باشه و هم پورت کردنش به سخت‌افزار جدید. و چون می‌خوام ازش استفاده هم کنم، باید با #لینوکس سازگار باشه تا بتونم از نرم‌افزار‌های نوشته شده برای لینوکس استفاده کنم. گزینه‌های که ازشون خبر دارم #آستریناس، خود لینوکس و #فری‌بی‌اس‌دی هستن. #نت‌بی‌اس‌دی هم گزینهٔ مناسبی هست و دقیقا برای این ساخته شده که پورت کردنش آسون باشه. ولی کارایی‌اش خوب نیست. از بین این گزینه‌ها فقط آستریناس از #راست استفاده می‌کنه.

اگر همه چیز به خوبی پیش بره، به امید خدا می‌تونم حدود ۱ الی ۲ سال دیگه وارد توسعهٔ کرنل بشم.

So I'm thinking about #Asterinas which is a kernel written in #Rust and has #Linux compatible ABI. Having Linux compatibility is a great deal as you get most of the support for Linux for free.

I've messaged on their Zulip asking if Milk V Duo could be a good option for porting. I wonder if they've got an active and vibrant community. I haven't received a reply yet.

There is also #Redox but I don't like licensing my code under MIT. And it's an entire OS and not just a kernel.

If you know a community about OS/kernel development and bare metal development as well, I would appreciate an invite.

@AsahiLinux It's sad to hear, but I'll accept that decision.

Please sent him my regards, cuz he's being missed already in the Fediverse (maybe he rejoins on a more private account, IDK...)

Let him, know he's based af and that the way @linuxfoundation handled the "Anti-#Rust - Gang" is just inexcuseable and that I wish for @torvalds et. al. to not just take notes but actual #consequences given that the reasons that made @marcan@treehouse.systems quit are systemic!

BTW: here's his personal blogpost for everyone else who also cares...

okay #osdev mastodon, enlighten me:

I’m building out my virtual memory alloc right now and it appears all other production kernels use some sort of *intrusive tree* for that. Why is that?

My thinking is: I already have a kernel heap thats “wired” aka directly allocated and mapped. And all virtmem impls I could find call out to *some* “backing allocator” anyways to allocate new tree nodes.

So if they aren’t fully allocation free anyway, why don’t I just use a sorted growable vec of entries allocated from the kernel heap?
What’s the advantage of intrusive data structures here that im missing?

It's never too late for an ambitious goal and to learn something new. I'm reading "Linux Kernel Programming - Second Edition" by Kaiwan N. Billimoria [1]. Chapter two brought back a lot of memories. Glad that "make menuconfig" and the like are still around even after so many years I didn't touch them. Wish me luck on my journey to contribute to the Linux Kernel one day.
