From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

lmao at the guy downvoting all the Nice
The nice chain shows how nice Lemmy is because the 4th one didn't get downvoted to oblivion

69, interrupted with a period? Not nice

Here's the TL;DR from Phoronix:
#AMD
-
AMD P-State Preferred Core handling for modern Ryzen systems. This is for leveraging ACPI CPPC data between CPU cores for improving task placement on AMD Ryzen systems for cores that can achieve higher frequencies and also helping in hybrid selection between say Zen 4 and Zen 4C cores. This AMD Preferred Core support has been in development since last year.
-
Performance gains on AMD 4th Gen EPYC
-
AMD FRU Memory Poison Manager merged along with other work as part of better supporting the AMD MI300 series.
-
AMD has continued upstreaming more RDNA3+ refresh and RDNA4 graphics hardware support into the AMDGPU driver.
#Intel
-
Intel Xeon Max gains in some AI workloads
-
Intel FRED was merged for Flexible Return and Event Delivery with future Intel CPUs to overhaul CPU ring transitions.
-
Reworked x86 topology code for better handling Intel Core hybrid CPUs.
-
Intel Fastboot support is now enabled across all supported graphics generations.
-
Intel Core Ultra "Meteor Lake" tuning that can yield nice performance improvements for those using new Intel laptops.
-
Continued work on the experimental Intel Xe DRM kernel graphics driver that Intel is aiming to get ready in time for Xe2 / Lunar Lake.
Video, Filesystem & Network
-
Support for larger frame-buffer console fonts with modern 4K+ displays.
-
Dropping the old NTFS driver.
-
Improved case-insensitive file/folder handling.
-
Performance optimizations for Btrfs.
-
More efficient discard and improved journal pipelining for Bcachefs.
-
FUSE passthrough mode finally made it to the mainline kernel.
-
More online repair improvements for XFS.
-
Much faster exFAT performance when engaging the "dirsync" mount option.

I wonder what an Intel Core hybrid CPU is
It refers to modern Intel CPUs where there are two types of cores - performance cores (P-cores) and efficient cores (E-cores). This is similar to ARM's big.LITTLE architecture which we've seen in smartphones for many years already.
See: https://www.intel.com/content/www/us/en/gaming/resources/how-hybrid-design-works.html
12th gen and up intel CPUs. All but a few have P and E cores.
Also like one weird i5 from about 10th gen.
I have a mobile 11th i7 one, sounds like no benefits 😞
Same boat. Good news is 11th gen generally gets better battery life than 12th+ because all those extra cores still eat power.
Bad news is I already get as bad as 30 minutes of battery life so IDK how 12th gen can be even worse.
I thought you saved power because the e-cores are more efficient for the same workload?
Yeah but this is Intel, they're not capable of doing something the most efficient way possible. E cores use less power than P cores, but that doesn't mean they're very good at getting the job done using the least amount of power. Currently (using Intel's management) 12th and 13th gen start a task on the P cores, and if it runs for longer than X time it gets shifted over to the E cores where it can churn away. Meteor lake has 3 stages of things since there's P cores, E cores, and LP E cores. If I remember right Meteor lake starts a task on the LP E cores, then shifts it to P cores, then shifts it to the E cores if it's taking too long. But Intel likes to blast the power away with turbo boost and runs the E cores way past their actual efficient zone unless you wrangle them back down. Sometimes it's faster to blast the task away on the P cores then return to idle, other times letting it churn away on the E cores forever is the best way.
Also all those extra cores being active still uses power. So if you went from a 4 core CPU to a 4 + 4 cpu now you have all the same power draw as the old one, plus the extra 4 efficient cores sipping at even more power. I think that's where 12th gen really suffers the most.

INTERNET FUNNY NUMBER LET'S FUCKING GOOOOOOOOOOOOO
Dropping the old NTFS driver.
Good stuff. Hasn't there always been confusion on mounting your NTFS drive using the old driver vs the new?
Indeed. But I think some confusion will still remain as long as the ntfs-3g FUSE driver is still included by distros. Because right now, you have to explicitly specify the filesystem type as ntfs3 if you want to use the new in-kernel driver, otherwise it would use ntfs-3g. And most guides on the web still haven't been updated to use ntfs3 in the fstab, so I'm afraid this confusion will continue to persist for some time.

GNU/Nice.
"nice" * 0.1
I am hoping for a smooth sailing of the new kernel.
Used Mainline to install it on Ubuntu 23.10. Together with Nvidia driver v550, it is working without an issue for me.
