NVIDIA – Simple Workaround for GCC15 in Fedora 42..

Adventures With Linux ™ Posted on by

Now that Fedora 42 is out, including GCC 15 (currently GCC 15.1.1-1) there is a simple workaround for compilation, thanks to Rudi Heitbaum.    The change is documented at https://github.com/NVIDIA/open-gpu-kernel-modules/pull/841/commits/448b236d893170edc8fc4dff029044948516352b, and must be seen as a workaround, not a fix, as it effectively removes some of the warnings/errors flagged by the latest GCC version.. For NVIDIA-Linux-x86_64-570.144/kernel/Kbuild, add the … Continue reading →

NVIDIA – Finally, a Fix for Kernel 6.15-rc..

Adventures With Linux ™ Posted on by

Thanks to efforts by Willy Frissen and Joan Bruguera Micó, I have managed to cobble together a patch for NVIDIA driver 575.51.02 and Kernel 6.15 – tested with 6.15-rc2.. The compilation failed with Kernel 6.15 due principally to changes removing obsolete EXTRA_CFLAGS and replacing it by ccflags-y, and del_timer_sync replacement by timer_delete_sync: …………………… nvidia/nv.c:31:10: fatal error: nv-firmware.h: … Continue reading →

NVIDIA – GCC15 on Fedora 42 Wrecks Compilation – and a Workaround..

Adventures With Linux ™ Posted on by

Recently updated the test system to Fedora 42, and everything seemed OK (including the latest VMware Workstation) – except the NVIDIA driver install.. The latest driver 570.124.04 compiles and installs OK with GCC14 and Fedora 41, on 6.13.x and also 6.14-rc kernels, but the NVIDIA source install scripts/tests etc. seem to be completely useless when compiling under … Continue reading →
