Five months later, some of the Radeon Open eCosystem components have made it into Fedora for easier installation but the HIP and OpenCL front-ends to ROCm haven't yet been successfully packaged...

Linux 5.18 is bringing many random/RNG improvements thanks to the work of kernel developer Jason Donenfeld. One of the changes though that had to be backed out during the merge window was trying to get /dev/random and /dev/urandom to behave exactly the same. While reverted for now with the 5.18 code, Donenfeld has prepared a change that should get it into good shape for major architectures with the next kernel cycle...

As a Linux kernel change for benefiting AMD CPUs going back to Zen 1 and for matching behavior Intel has had in place since the Core 2 times, AMD submitted a patch for having the Linux kernel use the MWAIT instruction instead of HALT for when the system isn't using the CPU idle driver either for C-states being disabled by the BIOS or the driver not part of the kernel build. In turn this can lead to around a 21% improvement in exit latency on affected systems...

Here is a combination not normally expected... Microsoft engineers have submitted patches for review enabling AMD GPU hot-plugging support with the Radeon "AMDGPU" Linux kernel driver...

When it comes to system recovery on Linux, users are most often only left with a command-line for trying to recover from a failed kernel boot, borked boot loader configuration, or other show-stopping problems. With Fedora Workstation right now they have only their CLI-based Linux recovery process but are eyeing the possibility of creating a complementary GUI-based recovery environment...

GNU Compiler Collection developers are working towards the stable release of GCC 12 in the next month or so as GCC 12.1.
