Linus Torvalds just christened the Linux 6.1-rc7 kernel as what is now expected to be the second to last release candidate before Linux 6.1 is officially released in December...
Talked about for over two years now has been a "readfile" system call to efficiently read small files. This should be a win when dealing with small files like those exposed via sysfs while it's taken time to come together and stalled out several times. This week Greg Kroah-Hartman has updated the readfile patches leading to hope that this new syscall might finally be on a path for mainlining...
While these days the Intel-owned Habana Labs Linux software stack is a shining example of an open-source AI accelerator solution with mainline kernel driver support and also helping bring together the new compute accelerator subsystem, it wasn't always so blessed. Initially there was the closed-source user-space bits that fortunately last year was opened up with SynapseAI Core...
While for years Intel has been very well regarded -- and rightfully so -- for their open-source Linux hardware support, occasionally there are exceptions. One such exception currently is Intel's IPU6 drivers for their MIPI cameras found on many newer Alder lake laptops and presumably upcoming Raptor Lake laptops too. The IPU6 drivers remain outside of the Linux kernel and will still likely be that way for sometime...
With the Linux 6.1-rc7 kernel set to be released later today, it will become easier making use of the AMD P-State driver for that enhanced CPU frequency scaling driver intended for Zen 2 and newer EPYC/Ryzen platforms that make use of ACPI CPPC...
Jason Donenfeld of WireGuard fame has been working the past several months of adding getrandom() to the vDSO for achieving better performance and working the needs of user-space developers. Early results have been impressive and this week Donenfeld sent out the seventh iteration of these patches...
