Linux 6.11 Likely To Land DM-Verity Multi-Buffer Hashing For Big Speed Boost

Fri, 07/05/2024 - 21:48
One of several nice Linux performance optimizations recently by Eric Biggers of Google has been speeding up DM-Verity via multi-buffer hashing. DM-Verity is used for transparent integrity checking of block devices and this multi-buffer hashing code looks like it will land with the upcoming Linux 6.11 cycle...

Linux Looking To Make 5-Level Paging Support Unconditional For x86_64 Kernel Builds

Fri, 07/05/2024 - 03:48
It's been nearly one decade since Intel began working on 5-level paging support for the Linux kernel to allow for greater virtual and physical address space with expanding memory sizes. The 5-level paging kernel-side bits were upstreamed back in Linux 4.12 in 2017 and enabled by default since 2019 with Linux 5.5. Intel CPUs for a while (since Ice Lake) have supported 5-level paging and AMD CPUs too since Zen 4. The Linux kernel may move to unconditionally enabling 5-level paging support for x86_64 kernel builds...

getrandom() In The vDSO Aims For Linux 6.11 To Provide Faster Yet Secure User-Space RNG

Thu, 07/04/2024 - 04:00
In the making the past two years by developer Jason Donenfeld (of WireGuard fame) is adding getrandom() to the vDSO in the name of better performance. In some tests this has yielded as much as a ~15x speed-up to performance for user-space obtaining crypographically secure random number generation. It's looking like for the upcoming Linux 6.11 merge window, this work will finally be merged...

Linux's DRM Panic "Screen of Death" Sees Patches For QR Code Error Messages

Thu, 07/04/2024 - 02:05
Linux 6.10 introduces DRM Panic for providing a new panic screen in case of kernel errors and situations where the VT support may be disabled. This new kernel functionality is akin to Windows' Blue Screen of Death or thanks to open-source can be adapted to take on other forms such as a black screen of death and conveying monochrome logos rather than ASCII art. New patches provide for the ability to show QR codes of error messages within the DRM Panic screens...

Meta Sees ~5% Performance Gains To Optimizing The Linux Kernel With BOLT

Thu, 07/04/2024 - 01:08
For years Meta/Facebook has been exploring using BOLT with the Linux kernel to optimize the layout of the Linux kernel binary. Since BOLT was upstreamed into LLVM, they've continued work around BOLT'ing the kernel. There is now a public guide for carrying out a BOLT-optimized Linux kernel build and roughly 5% better system performance to expect from such an optimized kernel...
