I am writing this message from 13.2 machine with i3-12100F (must be an Alder Lake; no integrated graphics in this one, though) in B660 motherboard. Previously the same machine was running 13.1. If it matters, I have multiple ZFS pools, including root on ZFS mirror. According to powermon(8) my package normally consumes less than 10W. I do not think that the support for an Alder Lake got worse in -CURRENT. -- Alexey I cannot receive HTML mail at this account. Hi, I am a signature virus. Add me to your signature to help me spread.

Performance is pretty bad compared to my 12 year old Ivy Lake, but surprisingly fast with all 12 threads on my ThinkPad T16 running. a 1180p video runs at about 13% of the total CPU capacity. glxgears get a rather paltry 900 FPS.

There is a bug, probably in hardware, that affects page invalidation on E-cores, but a workaround changes the mechanism on the E-cores to compensate.

I have been working on scheduler changes, but slowly. Things work surprisingly well without them though. An E-core is slower than the first thread on a P-core, but faster than the second thread. The scheduler puts fewer processes on the E-cores because of the shared cache in groups of 4 CPUs (vs 2 for SMT on the P-cores). Of course, with enough processes, they all get used. > Interested to hear from users using these CPU's right now in there system! > The Reason I ask is that I'm interested in upgrading my home server > hardware :-). I’m running -current on an i7-12700K, and it feels fast compared to my i7-10700K. Mike
Status of Alder and Raptor lake on FreeBSD Current
Hello current mailing list, I was wondering what the status of Alder/Raptor lake support is on FreeBSD? Does it boot? Integrated graphics are supported from what I recall with the newest drm drivers. Are there any plans for changes to our scheduler to account for efficiency and performance cores? Are there real world downsides of not having such a scheduler when running an Alder or Raptor lake CPU? Interested to hear from users using these CPU's right now in there system! The Reason I ask is that I'm interested in upgrading my home server hardware :-). Regards Dries
