“The X86_NATIVE_CPU Kconfig build time option has been merged for the Linux 6.16 merge window as an easy means of enforcing “-march=native” compiler behavior on AMD and Intel processors to optimize your kernel build for the local CPU architecture/family of your system.
The CONFIG_X86_NATIVE_CPU option is honored if compiling the Linux x86_64 kernel with GCC or LLVM Clang when using Clang 19 or newer due to a compiler bug with the Linux kernel on older compiler versions.”

“Dammit. Case sensitivity is a BUG. The fact that filesystem people still think it’s a feature, I cannot understand. It’s like they revere the old FAT filesystem so much that they have to recreate it – badly.
Hint: ❤ and ❤️ are two unicode characters that differ only in ignorable code points. And guess what? The cray-cray incompetent people who want those two to compare the same will then also have other random – and perhaps security-sensitive – files compare the same, just because they have ignorable code points in them.”

“Unlike Kpatch and Ksplice, which patch the running kernel without rebooting, Live Update Orchestrator takes a hybrid approach. While it requires a reboot, it focuses on keep critical devices running, which minimizes the side effects of the update.”
- Google is developing Live Update Orchestrator, a new system for updating the Linux kernel with minimal downtime.
- This technology is focused on cloud environments, allowing hypervisors to be updated without completely interrupting running virtual machines.
- Live Update is a specialized reboot process that keeps certain devices operational through kernel transitions.
- A new device infrastructure (dev_liveupdate) is introduced to integrate with the Live Update Orchestrator system.

“Testing with 100 boots shows an average boot saving in acpi_init of ~35000
usecs.”
