The Many Changes Lining Up So Far For The Linux 5.1 Kernel
In our close monitoring of the mailing list activity and many "-next" Git branches, here is some of what is on the table for the Linux 5.1 kernel cycle that will kick off in the weeks ahead:
- Io_uring for fast and efficient I/O that should be quite promising over the long-term.
- Better boot performance for big NUMA servers.
- Shared Virtual Memory for Nouveau with this open-source NVIDIA driver beginning to tap into the Linux kernel's Heterogeneous Memory Management (HMM) infrastructure.
- Intel has finally enabled Fastboot support by default for recent generations of graphics hardware.
- Coffeelake GVT support for Intel graphics virtualization.
- A user-space API addition to the Intel driver for working with Icelake and Intel's new VA-API media driver.
- AMDGPU DC seamless boot was merged along with various fixes and improvements.
- The Arm Komeda driver is being added to the DRM subsystem.
- Bitmain SoC support for the BM1880 and Sophon Edge developer board. This is a 64-bit ARM chip plus having a tensor platform and also a RISC-V core albeit not yet supported by the current code.
- Qualcomm FastRPC is being mainlined for offloading work from the application processor to the DSP on supported SoCs.
- Also on the Qualcomm front is mainlining its vibrator driver.
- Better AVX-512 tracking to allow for user-space to work on more optimal task placement.
- MacBook Pro keyboard/touchpad support for the latest generations of devices, albeit this might be pushed back from 5.1 as the code hasn't been staged yet.
- Improved Thunderbolt support for older Apple hardware.
- A new async driver probing option.
- Addressing more quirky hardware on the HID front, mostly various ASUS and Lenovo laptops.
- Intel WiFi support for Cyclone Peak and other new WiFi chips.
- Devlink health reporting and recovery system made it into the networking subsystem.
- The Google Chrome OS Wilco driver has now been staged in its 5.1 branch for this new embedded controller (EC) for new Chromebooks.
- Support for the Fireface UCX high-end audio solution.
- The new TEO CPU idle governor for tickless systems.
- Atomic replace support for kernel livepatching.
- The XGI display driver is being EOL'ed.
Stay tuned for more coverage of the Linux 5.1 kernel cycle once it kicks off and then the subsequent benchmarks.
