Linus Torvalds' Latest Commentary Against -O3'ing The Linux Kernel

Phoronix - Sat, 06/25/2022 - 02:44
This shouldn't be too surprising considering some of Linus Torvalds past commentary about compiler optimizations and bad experiences long ago with GCC, but Linus Torvalds is not interested in seeing a tunable Kconfig option for using the -O3 compiler optimization level for building the Linux kernel without substantial justification...

D3Cold-Off Power Savings Being Prepped For Intel's Linux Driver For Arc Graphics

Phoronix - Sat, 06/25/2022 - 01:53
Intel's open-source Linux graphics driver developers remain very busy preparing the open-source driver stack for Arc Graphics DG2/Alchemist hardware. While much of the base enablement work is complete and now with Linux 5.19 the compute support is even exposed to user-space, one of the areas seeing more work in recent times has been around power management...

Linux Full Disk Encryption Performance For The AMD Ryzen 7 PRO / HP Dev One

One of the great defaults when installing Pop!_OS or receiving a pre-loaded laptop/desktop from System76 or the new HP Dev One is that it encourages full-disk encryption and prominently shown during the install process. I highly recommend full-disk encryption especially for laptops. As it's been a few years since running benchmarks looking at the overhead of LUKS encryption, here are some benchmarks of Pop!_OS 22.04 on the HP Dev One with the full disk encryption enabled and then a fresh install without encryption.

Fedora 37 Looks To Ship With Stratis Storage 3.1 Support

While many Red Hat open-source projects end up being relatively instant successes that then end up being widely adopted in the open-source community, Red Hat's Stratis Storage effort seems to be trending as one of the exceptions. Red Hat continues investing in Stratis but it doesn't seem to have the sizable adoption or widespread interest that tends to come with most of their projects. In any event, Fedora 37 later this year should ship with the newest Stratis tech...
