… And Antonio Huete Jimenez has described the few steps required to install it.
If you’re running bleeding-edge DragonFly, you’ll need to rebuild world and kernel after this recent change to interrupt counting from Sepherosa Ziehau.
Simon ‘corecode’ Schubert tagged 2.3.1, which is still in the development branch, so don’t update unless you were already at 2.3. There’s a nice list of commits that went into this tag.
Aggelos Economopoulos added an interesting feature for virtual kernels: the memory of a given virtual kernel is now accessible directly at /proc/$pid/mem .
Antonio Huete Jimenez wrote up his experiences using pkg_dry on DragonFly, which were mostly successful.
He followed up with a script that takes care of the initial setup for pkg_dry, and noted that following pkg_dry in CVS is the best idea at this point, as it’s going through rapid development.
It should be possible to point pkg_dry at pkgbox.dragonflybsd.org or one of the mirrors, and perform binary-only remote installs and upgrades of pkgsrc packages.
Sepherosa Ziehau has added the ability to use High Precision Event Timers (HPET) in DragonFly, based on FreeBSD code. It’s experimental, and he has instructions on how to find if your hardware supports it. It’s apparently a much faster timer than what is used with ACPI, though I do not have details on how that translates into real-world performance.
Johannes Hofmann has an initial version of the kqemu kernel module installable as a pkgsrc package, so that it can be managed the same as with other third-party software. I don’t know if this will actually make it into pkgsrc, but it would be nice if it did.
I had mentioned the new malloc in DragonFly before, but Matthew Dillon has a nice explanation of its performance improvements and the relationship to the existing slab allocator.
Hasso Tepper, who has been working very hard on pkgsrc on DragonFly, has a few strange pkgsrc issues he’d like help on. Anyone have ideas? (Follow the thread to see what’s been done so far.)
Make Hasso Tepper’s life a bit easier and take heed of this list: Maintaining stuff in pkgsrc.
Edit: Meant to publish this a bit ago; missed it. Sorry!
The 2.2.1 release of DragonFly, rounding up changes since the release (I don’t have a list), should be tomorrow.
