Toby KurienOk, so check this out. I raved about how magical <a href="https://mastodon.social/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FreeBSD</a> <a href="https://mastodon.social/tags/linuxulator" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#linuxulator</a> is, but it gets even better! In my Ubuntu linux jail, I downloaded the source for the <a href="https://mastodon.social/tags/mobian" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mobian</a> kernel, installed cross-compiling tools, compiled the kernel and modules, copied to an sdcard, and booted up the kernel on my <a href="https://mastodon.social/tags/pinephonepro" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pinephonepro</a> 🤯 So, on my amd64 FreeBSD, I used a translation layer to load up Ubuntu Linux, used it to cross-compile a Linux kernel for arm64, and booted that up on a device! How unbelievable is that?!?

Toby KurienOh wow, the <a href="https://mastodon.social/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FreeBSD</a> <a href="https://mastodon.social/tags/Linuxulator" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linuxulator</a> is just magic! I setup an Ubuntu <a href="https://mastodon.social/tags/LinuxJail" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LinuxJail</a> as described in the linked wiki and was able to compile and flash <a href="https://mastodon.social/tags/Arduino" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Arduino</a> code to my Uno using <a href="https://mastodon.social/tags/PlatformIO" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PlatformIO</a>, which is absolutely mind blowing because the tools for compiling are not available for "freebsd_amd64", yet in this Linux environment (not emulated, not a VM, just a translation layer), the Linux binaries were able to compile and then flash to the USB device (using the FreeBSD kernel… <a href="https://tobykurien.com/post-1744211915" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://tobykurien.com/post-1744211915</a>

Felix Palmen 📯<a href="https://mastodon.online/@alexr" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@alexr</a> Sorry, but it really doesn't make sense to me to compare anything just regarding <a href="https://techhub.social/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linux</a> vs <a href="https://techhub.social/tags/Linuxulator" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linuxulator</a>. The kernel(!) as a source of indeterminism is very unlikely, everything else (like <a href="https://techhub.social/tags/glibc" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#glibc</a> where the allocator is implemented) is the same. I don't see what I would gain from that huge amount of work here.

Felix Palmen 📯<a href="https://mastodon.online/@alexr" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@alexr</a> Are you suggesting that the same GCC (native <a href="https://techhub.social/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linux</a>, not cross-target) would produce different code when the Kernel isn't "real" <a href="https://techhub.social/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linux</a>, but <a href="https://techhub.social/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FreeBSD</a>'s <a href="https://techhub.social/tags/Linuxulator" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linuxulator</a>?I still see no sane way to check this, maybe short of installing this very same version on a Linux system and comparing assembler output... 🤔 but it doesn't seem like a likely thing to me 🤷‍♂️
