In addition to specific problems with some motherboards, dragonflybsd usually works very well on AMD Zen systems. Now, it has introduced some new drivers from FreeBSD, and the overall performance has been improved.
From the partial driver introduced by FreeBSD,Amdtemp driverThis is particularly noteworthy. This driver supports the temperature monitoring of AMD 0Fh, 10h, 11h, 12h, 14h, 15h, 16h, and 17h series processors. Among them, support for AMD family 17h covers Zen 1 and Zen 2, including threadripper and epyc.
In addition, there areAmdsmn driver。 This driver is used to support amd system management network (SMN) on AMD Zen system.
With the introduction of these drivers, the dragonflybsd team has made minor improvements to their code, which are currently located in the dragonflybsd code tree.
Like many BSD /Linux communities, DragonFlyBSD project leaders are Matthew Dillon impressed with AMD Zen 2 products, perhaps because of the continuous optimization of the project running experience on the AMD.
