Adventures With Linux ™ Posted on by

I have updated some test systems (x86_64 and aarch64) to pre-beta Fedora 32, which now includes GCC 10: $ gcc –version gcc (GCC) 10.0.1 20200216 (Red Hat 10.0.1-0.8) There have been a couple of problems with kernel compilation, but in each case there was already a patch/workaround available.. https://www.spinics.net/linux/fedora/fedora-arm/msg13193.html and https://lkml.org/lkml/2020/1/29/494 The most serious problem was a … Continue reading →

Kernel – Pre-Release Tests for 5.6-rc1 ..

Adventures With Linux ™ Posted on by

Kernel 5.6-rc1 should be out on Sunday, February 9th, but I noticed that early-version-test patches are already available for VMware 15.5.1, here:  https://github.com/mkubecek/vmware-host-modules/tree/tmp/workstation-15.5.1-k5.6 These patches gave clues to what might affect NVIDIA as well, and I managed to get a GIT version of 5.6-rc1-pre (dated February 5th) to compile OK, and was able to use this.   Of … Continue reading →

Adventures With Linux ™ Posted on by

NVIDIA have a Beta driver available, and this compiles OK with kernel 5.5.   Available from link here:  https://developer.nvidia.com/vulkan-driver I have installed this and – interestingly – it still gives a ‘tombstone’ at # startx, but appears to run OK despite that ?: [60044.039448] ————[ cut here ]———— [60044.043355] refcount_t: underflow; use-after-free.

Ethernet – If you Can’t Wait for 5.4.14, an Unofficial e1000e Patch for 5.4.13..

Adventures With Linux ™ Posted on by

As there is (so far) no sign of an update to the 5.4.x kernel series, I have uploaded a _very unofficial_ patch I had already created for 5.4.13, and I have tested this, and so far it seems to work OK..    It is based on an ‘earlier’ e1000e patch version found on linux/netdev.. https://www.spinics.net/lists/netdev/msg623693.html,  and thanks are … Continue reading →

NVIDIA – Another Kernel 5.5 Patch

Adventures With Linux ™ Posted on by

There is another (modified?) patch available for the latest NVIDIA driver and Kernel 5.5-rc ( see the NVIDIA Forum article at https://devtalk.nvidia.com/default/topic/1068332/linux/nvidia-driver-does-not-build-on-linux-v5-5-release-candidate-kernel/ ). I have applied this to driver 440.44 on Kernel 5.5-rc3, and it compiles OK, and loads/runs without the ‘tombstone’ that I experienced with previous versions. Robert Gadsdon.  December 24th 2019.

Kernel – 5.5-rc1 is Out. Breaks NVIDIA, but e1000e Finally Fixed?

Adventures With Linux ™ Posted on by

Kernel 5.5-rc1 has been released, and brief details are here:  http://lkml.iu.edu/hypermail/linux/kernel/1912.1/00242.html From limited tests so far, the Intel e1000e driver now seems to be working for all Intel NICs that use it, on my various systems. Patched VMware W/S 15.5.1 compiles OK, but NVIDIA 440.36 fails: ………… In file included from /home/rgadsdon/kernel/NVIDIA-Linux-x86_64-440.36/kernel/nvidia-drm/nvidia-drm-drv.c:30: /home/rgadsdon/kernel/NVIDIA-Linux-x86_64-440.36/kernel/nvidia-drm/nvidia-drm-connector.h:30:10: fatal error: drm/drmP.h: No … Continue reading →

Kernel – 5.4-rc2 is Out. No Change from rc1, so far?

Adventures With Linux ™ Posted on by

Kernel 5.4-rc2 has been released, and brief details are here: http://lkml.iu.edu/hypermail/linux/kernel/1910.0/07213.html The odd behaviour of VMware and NVIDIA compiles still occurs, but there are patches submitted (see comments under -rc1 article https://rglinuxtech.com/?p=2614 for more details).   So far, I have not seen a fix for the NVIDIA compile failure.
