Thanks to Pierre-Alain Toret, we know 2008 Macbooks and Samsung NP370R5E-A04FR laptop models support Dragonfly. If you have DragonFly running on a model not mentioned, please add it.
There’s a refresh of the iwm(4) driver in DragonFly, which will apparently help most for iwm-9000 and iwm-9260 owners.
I don’t know which product names correspond with those chipsets, but you may be able to tell who you are. Interesting note: original driver via OpenBSD, then synced from FreeBSD version. Cross-pollination!
i915 DRM has been updated to match the Linux 4.8.17 version, in DragonFly. It includes some OpenBSD work too, interestingly.
This is minor, but I’ll mention it because it might bite you someday: if you are using powerd to minimize CPU power usage, and also trying to push a high data rate through your serial port, you might drop characters. It’s mentioned in the powerd(8) man page, which has an entertaining bugs section.
If you have an Elantech touchpad IC type 15 on your laptop (and you do if it’s a ThinkPad L480 or Huawei Magicbook), it’s now supported in DragonFly. Thanks to K Staring for the fix.
The i915(4) driver now supports some newer models of Intel GPU, thanks to Francois Tigeot.
Francois Tigeot has made a number of updates to the ttm and radeon code, bringing it line with the Linux 4.9 kernel version. If you have a radeon(4)-using video card, you may find this useful.
Also, evergreeen and radeonsi chipset users have acceleration disabled. You may not notice depending on your workload.
As an example of how old design decisions have lasting effects, the POSIX standard still calls for terminal output to accommodate mechanical delay, as noted in this DragonFly commit – i.e. if output was still a line printer instead of a glass TTY, or, as it is 99.9% of the time today, xterm or puTTY or etc. etc.
After 56k, I stopped paying attention, but apparently there’s stated baud rates of 460,800 and 921,600. And your DragonFly terminal can handle them, too.
Do you have a Coffee Lake Intel CPU? Cause corepower(4) in DragonFly now supports it.
For anyone who might need it in the future: some notes on getting Synaptics touchpads and trackpoints working.
Jails on DragonFly now have their own sysctl tree, inherited from defaults. And are no longer MPLOCKed.
The radeon driver support on DragonFly now matches Linux 4.7.10. Update and test, especially if you have one of the chipsets mentioned.
If you have an AM4 motherboard and also can’t EFI boot DragonFly on it, this recent change may fix that for you.
Also, if you are using a Corsair keyboard, this commit may be useful to you.
It’s supported, and given how well DragonFly supports SMP and the number of processors Zen 2 supports, it’s a no-brainer if you’re in the market for a new server.
Francois Tigeot has updated the radeon driver in DragonFly to match what’s in Linux kernel 3.19.8. No, wait, I took too long to post this cause there’s been so many things, so now it’s up to 4.4.180.
If you are running an em(4) or igb(4) device in DragonFly, Sepherosa Ziehau has updated the drivers. This brings it to Intel driver versions em-7.7.4 and igb-2.5.6.
This could be an In Other BSDs item, but it’s worth highlighting: saugns is a “Scriptable AUdio GeNeration System”; a utility for generating sounds – specifically FM modulation, in a way that will make you think “synthesizers!” There’s a whole language behind it, and the program, as the author, Joel K Pettersson, points out, compiles with no trouble on every BSD.
The module formerly known as ‘radeonkms’ is now just plain ‘radeon’. There have been changes in other commits, but this is the only usage change.
