Linux 6.5 Slated To Add Provisioning Primitives For Thinly Provisioned Storage
Another feature scheduled to be sent in for the upcoming Linux 6.5 kernel merge window is introducing support for provisioning primitives for thinly provisioned storage with the Device Mapper (DM) code...
Linux 6.5 Adding Qualcomm Adreno 690 Open-Source GPU Support
The upcoming Linux 6.5 kernel is poised to add support for Qualcomm's Adreno 690 GPU to the open-source MSM kernel graphics/display driver. The A690 is notably used by the Snapdragon 8cx Gen 3 (SC8280XP) platform that in turn is what's found inside the Lenovo ThinkPad X13s laptop and other hardware...
XFS Large Extent Counts Feature No Longer Considered Experimental

Patches being queued ahead of the upcoming Linux 6.5 kernel merge window prepare initial support for DEXCR that is found in recent Power ISA specifications...
Libreboot To Provide New Firmware ROMs With CPU Microcode Removed
CPU microcode updates are commonly done in the name of security fixes and resolving functionality issues.. In recent years, CPU microcode updates have been a much more common -- and important -- occurrence. While all modern CPUs rely on microcode it's just a matter of whether the version used is baked into the hardware or an updated version loaded by the BIOS or OS at boot time, a "vocal minority" of users are unhappy with CPU microcode being included in Libreboot ROMs. Thus moving forward there will be alternative builds of Libreboot for different motherboards with the CPU microcode stripped out in the name of software freedom...
Linux 6.5 Adding Support For NCT6799D Sensors Found In Various Newer Motherboards
If your newer desktop motherboard has a NCT6799D Super I/O controller or one of the variants like NCT6799D-S, the Linux 6.5 kernel is set to introduce support for this ASIC in order to expose hardware sensor support under Linux...

The Flash-Friendly File-System (F2FS) is preparing to land async buffered write support into the Linux kernel as another performance win for this flash-optimized file-system...
Red Hat Aiming To Address IBRS Mitigation Still Being Too Costly On Performance
Red Hat engineers are working to deal with Indirect Branch Restricted Speculation (IBRS) being too costly for mitigating Spectre V2 and Retbleed on older Intel Xeon Scalable processors. A new patch has been floated to disable IBRS when idle and is working out well at least for Red Hat Enterprise Linux 9 while isn't clear yet if it will be accepted into the upstream kernel...
SVT-AV1 1.6 Squeezes Out Even More Performance For CPU-Based AV1 Encoding
SVT-AV1 1.6 is now available as the latest version for this leading CPU-based AV1 encoder that is now enjoying 30~40% faster performance with high quality presets...
Revised Intel Shadow Stack Support May Be Ready For Linux 6.5
Intel engineers had sent in Shadow Stack support for Linux 6.4 as this feature part of Control-flow Enforcement Technology (CET) but it hit a last-minute snag during the merge window with issues raised by Linus Torvalds. Now it looks like the cleaned-up Shadow Stack code will be re-submitted for the upcoming Linux 6.5 cycle...
