dfly drm irq

Here’s something that doesn’t have an immediate impact now, but will be useful down the road: Francois Tigeot has been working on DRM support in DragonFly, and has been quite successful with Intel video support.  His strategy has been to adopt Linux methods where possible, to reduce the amount of support work.  The payoff has been excellent, and prompt,  accelerated video support in DragonFly.  The most recent work is “git: drm: Implement parts of the Linux irq subsystem“, which is going to come in handy for someone, I’m sure.

Some nice tech explanations this week.

Microcode updates on DragonFly

One side effect of Meltdown/Spectre are CPU microcode (firmware) updates.  For future needs: sysutils/devcpu-data is the port that has the updates for Intel, and cpucontrol(8) is the program you run on DragonFly to add them.

I haven’t used this myself, yet, so I can’t tell you how necessary an immediate update could be – but you will probably want to use it soon.

Update: Newer CPUs might require this sizing change.

Update update: a better explanation of applying microcode updates.  There’s new ones out, too.  (via)
