Kernel: AMD Navi 10 Firmware and Linux 5.4 Additions

AMD Navi 10 Firmware Finally Lands In The Linux-Firmware Tree
While AMD has provided open-source Radeon RX 5700 series (Navi 10) support since launch and that code since worked into the various mainline code-bases from the Linux kernel to Mesa, one kink in their support has been their binary microcode images not being available from the reference linux-firmware.git location as needed to initialize the hardware. That Navi 10 firmware/microcode issue has finally been rectified with the images landing this morning.
Up until now any Radeon RX 5700 series Linux customers or distribution/third-party driver packagers have had to pull these binary bits from this Navi10 directory on the personal site of AMDGPU lead maintainer Alex Deucher. Via his site is where he normally stages these binary microcode files until landing in linux-firmware.git as the de facto location for all Linux drivers' firmware files.

Wireless USB + UWB Demotion Goes Ahead For Linux 5.4
Back in August I noted that Wireless USB and Ultra Wideband would be deprecated within the Linux kernel and that is indeed happening for Linux 5.4.
The Wireless USB (WUSB) and Ultra Wideband (UWB) subsystems within the Linux kernel were already orphaned for years with having no maintainer while now they are officially deprecated and demoted to the kernel's staging area. If no one steps up soon to maintain the code, it will be dropped in forthcoming kernel releases.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
