  • The common sketchy performance advice is to disable mitigations in the kernel, this post is about disabling mitigations in Intel’s userspace graphics stack because it’s already checked in the kernel.

    Assuming you meant disabling kernel mitigations, since AFAIK audio stuff doesn’t usually use OpenCL:

    Has anyone else here disabled it?

    Nah, my understanding is it’s not worth it on newer CPUs, and in some cases, the microcode expects things to be mitigated for best performance. Older CPUs (pre-2019ish) it does make a difference though.

    But you’re welcome to benchmark it, and see if it makes a worthwhile difference on your CPU. Kernel mitigations are easy enough to turn on and off.







  • Perhaps there was an easier lighter-weight way of doing this?

    Yeah, SSH tunneling. What I would do (and have done in the past) is something like:

    ssh -L 8080:192.168.0.1:80 myserver
    

    That will forward port 8080 on your host to port 80 on 192.168.0.1, so you can access your router’s web UI with http://localhost:8080/ in your own web browser.

    You can also setup full tunneling with SSH, but that requires messing around with SOCKS and I usually can’t be bothered.

    My understanding is previously the kernel would crash on systems with more RAM than the address space, so there’s now a patch to ignore the anything above the max address supported (e.g. 32bit without PAE, 36bit with PAE). More RAM was never supported, so I think the author of the article has misunderstood or oversimplified what’s been done.
