ARM64 – Pi 4 USB Problems – And a Messy Fix..

Adventures With Linux ™ Posted on by

After some delay, I finally had a ‘good’ cooling solution for my 8GB Pi4, and resumed testing.. The last Kernel version I had running on it was 5.9-rc4, and everything seemed to be working OK (including 8GB of memory recognised). I then updated to 5.11.18, and found that none of the USB ports worked: # dmesg |grep … Continue reading →

Compiler – Fun with CLANG – Kernel, NVIDIA, and VMware…

Adventures With Linux ™ Posted on by

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 →

NVIDIA have released driver 460.67, and details are here:  https://forums.developer.nvidia.com/t/linux-solaris-and-freebsd-driver-460-67-long-lived-branch-release/172742 The details mention ‘5.11 release candidates’ but they probably should have said ‘5.12 release candidates’, as the previous driver worked OK with kernel 5.11, and this new one works OK with 5.12 (tested with 5.12-rc3) In other news, I should mention that the KVM/USB crash problems I … Continue reading →
