As usual, the next release of Linux includes new features, but this time – with 5.15 – it now includes new NTFS read/write support in the kernel. The code for this is from Paragon, and is already in the 5.15 codebase on git, so I decided to test it.. As this was pre-RC code, it also flagged … Continue reading →
I had spent far too much time trying to solve the Pi4 USB conundrum ( see https://rglinuxtech.com/?p=2922 ) but did recently find that the 5.14-rc kernels enabled the USB3 hub, although USB2 still failed to function. I then updated u-boot to the ‘latest’ version, and now everything (finally..) works as it should, again..: Updated u-boot to latest … Continue reading →

I have been carrying out some preliminary tests to see how feasible it is to compile the Linux Kernel, and NVIDIA drivers, and VMware, using the ‘alternative’ to GCC – CLANG.. The kernel compile is relatively easy, and well documented: # make CC=clang HOSTCC=clang -j8 (for a 4-core system) The compile seems to be slower than GCC, … Continue reading →
