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 →

NVIDIA – Inconsistent Install Problems with Latest Drivers..

Adventures With Linux ™ Posted on by

Systems are Intel Dual-Xeon with Fedora 41 and GCC 14.2.1..  Kernel compiled from kernel.org source.. Starting with driver 550.144.03, and now with the latest driver 570.86.16 I have been experiencing odd and inconsistent problems with the usual install process.. Running ./NVIDIA-Linux-x86_64-570.86.16.run fails with “ERROR: Unable to load the kernel module ‘nvidia-drm.ko’.” and later “-> Kernel module load … Continue reading →

Kernel – Pre-6.14rc testing – VMware OK, and Simple Fix for NVIDIA..

Adventures With Linux ™ Posted on by

Kernel 6.14-rc1 will be released soon, and I have been testing the code changes submitted so far (February 26th) with the following results: VMware 17.6.2 – including ‘clean up’ patchset from https://github.com/64kramsystem/vmware-host-modules-fork/tree/workstation-17.6.2-sav – compiles OK, but with the usual host of ‘warnings’, which seem to be accepted as good-enough these days.. NVIDIA 550.144.03 compile fails with: ………………….. … Continue reading →

VMware Workstation – Multiple Patch Forks Since Broadcom..

Adventures With Linux ™ Posted on by

I would like to start by thanking Michal Kubeček for his many years of expert support of the VMware vmmon/vmnet modules for later kernel versions.. Since the Broadcom takeover of VMware, his patches have been forked multiple times, for 17.5.2 and now 17.6 support, with varying degrees of success..    I have tested most of these and – … Continue reading →

Kernel – 6.11 Pre-Testing.. OK so far with Latest NVIDIA and VMware (patched)

Adventures With Linux ™ Posted on by

Tested the latest (July 21st) git version of pre-release Kernel 6.11, and this was OK with NVIDIA 555.58 and (patched) VMware 17.5.2..  (from https://github.com/nan0desu/vmware-host-modules/tree/tmp/workstation-17.5.2-k6.9-sharishth ) Obviously, there will be more potential for ‘breakages’ before -rc1 is released in a weeks time..
