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 →

Thanks to mbod, there is a simple kernel patch to restore the Kernel 5.8 ‘inherited taint’ behaviour to Kernel 5.9, and the detail is in this thread: https://forums.developer.nvidia.com/t/opencl-not-working-with-kernel-5-9/156941/6 I have applied this to Kernel 5.9.0, and NVIDIA driver 455.28 now installs and loads/runs OK. Until a proper fix is available, this will – of course – need … Continue reading →
