I ordered a used Intel i7-4790 (SR1QF) for my home server. I am excited to double my threads, from 4 to 8, which has been a little bit of a bottle neck for my i5-4590. It also increases the cache, clock speed, and adds hyper-threading. I love that I have gotten so much use out of this old computer!

There's one thing I haven't tried in #FreeBSD for hardware acceleration yet: xf86-video-intel.

Granted, this is the legacy driver, but I'll give this a shot to see if it somehow works with #Haswell. Maybe it does or maybe it doesn't? 🤷

Otherwise, I think I'm about to conclude that I can't get FreeBSD graphics acceleration on Haswell. At least, KDE performance is suboptimal compared to Arch Linux, where it's smoother and also reports the proper GPU rather than "llvmpipe". That or I'm still somehow doing something wrong, but if that's the case, then what is it that I'm doing wrong? Hmmm 🤔

#Benchmarking The Experimental #Ubuntu #x86_64_v3 Build For Greater Performance On Modern #CPU
With x86-64-v3 basically being #Intel #Haswell and #AMD Excavator or newer (with some exceptions like select Atoms), it would be really interesting too if #Canonical would consider an x86-64-v4 option for modern systems with #AVX512 support. It'd be really interesting to see at least an experimental Ubuntu x86-64-v4 build to see what that could mean for #servers and #HPC

Benchmarking The Experimental Ubuntu x86-64-v3 Build For Greater Performance On Modern CPUs

One of the exciting innovations currently being explored by Canonical ahead of the Ubuntu 24.04 LTS release is an x86-64-v3 build of the OS / packages.

今天折腾自己那可怜的老爷Haswell平台，发觉打开 Hyper-V 之后，Audio over HDMI 就不工作了。
图一中 Intel 社区人员给出的测试结果推测是支持 VT-D 的处理器会出现问题，但是没有 VT-D 功能的处理器不会出现这个问题。

自己根据图 2 的 MS TechNet 给出的临时解决方案是，将输出调整为 48KHz/24bit 后重启即可解决问题。（it works for me！）
图三为最终效果。
btw，系统版本是Win10 LTSC 21H2

吐槽：后面看了看发现早在2015年就有人报了，到2023年了它仍然没有被解决，只有workaround

Intel Display Audio and Hyper-V

A week ago I setup a new machine with a Gigabyte GA-Z97-HD3 motherboard and a Intel i5-4590 processor running Windows 10 Pro. I have all of the latest Intel drivers for video and the hdmi audio driver. I use the machine for a media server connected to my Samsung TV via HDMI. I had been having troubl...

What are proper ways to downclock/undervolt #Haswell processors? Thinking about using an old PC, shove a couple of hard drives in it to create a NAS from it.

@matt it seems to be #IvyBridge and #Haswell machines (my work desktop is ~5 years old). Although the kernel caused the regression there seems to be some debate about it being #Xorg related: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=925555
