Phoronix: Linux 6.5 Released With AMD P-State EPP Default, USB4 v2, MIDI 2.0 & More Hardware Bits

While at the start of Linux 6.5 cycle Linus Torvalds was concerned this release "may be one of those releases that may drag out", in the end it is releasing today and right on schedule. Linux 6.5 was just published rather than going into overtime without any extra release candidate...

Looking forward to the demonic 6.6.6 release.

Question: Do one still has to manually enable the P-State kernel flags, or do they come enabled by default?

amd_pstate.shared_mem=1 amd_prefcore=enable=1 initcall_blacklist=acpi_cpufreq_init

Depends on the Zen version and server/consumer host. You don't need to do anything on consumer Zen 4. It picks amd_pstate by default with a bare kernel command line.

On Zen server hardware, you still have to manually call the amd_pstate in the kernel command line. But a simple declarative of what the driver operation mode desired is all that is needed. Example: amd_pstate=active

It is not necessary to blacklist the acpi_cpufreq driver.

You can still use the amd_prefcore=enable in your example.

Just tried to install the new kernel 6.5.0-generic from the Mainline PPA and could not because of unmet dependencies.

libc6 >2.38

Been installing and running all of the prior 6.5-rc kernels with no issues.

Currently running Ubuntu 22.04.3 LTS [6.5.0-060500rc7-generic|libc 2.35]

Looking forward to the demonic 6.6.6 release.

It will be a hellava release. And kernel 6.6 might even end up being an LTS release, so 6.6.6 might be a kernel that never dies.

So it seems they now require a newer glibc.

If that is the case I'll just stay on rc-7.

Still think this is a configuration screwup on the part of either the devs or the mainiline ppa maintainers.
