Kernel – 6.4-rc Pre-release Testing.. Breaks NVIDIA, VMware OK..

Adventures With Linux ™ Posted on by

Usual caveat..  Not all changes are yet in place, and any code changes are suggestions/hacks only – not a expert recommendation! Testing an interim release (April 29th) of Kernel 6.4-rc, and NVIDIA 530.41.03 fails to compile: LD [M] /home/rgadsdon/NVIDIA-Linux-x86_64-530.41.03/kernel/nvidia-modeset.o CC [M] /home/rgadsdon/NVIDIA-Linux-x86_64-530.41.03/kernel/nvidia-drm/nvidia-drm.o CC [M] /home/rgadsdon/NVIDIA-Linux-x86_64-530.41.03/kernel/nvidia-drm/nvidia-drm-drv.o /home/rgadsdon/NVIDIA-Linux-x86_64-530.41.03/kernel/nvidia-drm/nvidia-drm-drv.c: In function ‘nv_drm_update_drm_driver_features’: /home/rgadsdon/NVIDIA-Linux-x86_64-530.41.03/kernel/nvidia-drm/nvidia-drm-drv.c:1439:18: error: ‘struct drm_driver’ has no member named … Continue reading →

Kernel – 5.15. Early Test for New NTFS Support..

Adventures With Linux ™ Posted on by

As usual, the next release of Linux includes new features, but this time – with 5.15 – it now includes new NTFS read/write support in the kernel.      The code for this is from Paragon, and is already in the 5.15 codebase on git, so I decided to test it.. As this was pre-RC code, it also flagged … Continue reading →

Fedora – Fun with ZRAM..

Adventures With Linux ™ Posted on by

Fedora 33 will be using ZRAM as standard for swap, rather than a partition or swapfile on disk.    I had no problem with this on a new F33 install (Odroid H2Plus) but after upgrading an existing Fedora 32 system it refused to initialise, and ‘/dev/zram0‘ did not exist.    Research revealed that the documentation for much of this … Continue reading →

Adventures With Linux ™ Posted on by

There is already an early NVIDIA 450.57 patch for Kernel 5.9, and thanks to Pete for the info, and Isaak I. Aleksandrov for the patch ..   This was not shown in the general list I had at https://gitlab.com/users/EULA/snippets, but the direct link is here:  https://gitlab.com/EULA/snippets/-/blob/55de41ae16851dc0fc7973901c1f71007b2a4efb/NVIDIA/450.57/kernel-5.9.patch I have tested this with the August 9th pre-release I used in … Continue reading →

Kernel – 5.9-rc – Preliminary Testing – Breaks VMware and NVIDIA, and VirtualBox..

Adventures With Linux ™ Posted on by

After all the excitement around the release of Kernel 5.8, I ran some tests on the work-in-progress git version (August 9th) of Kernel 5.9-rc1.   Obviously, there are more changes to come before RC1 is actually released.. NVIDIA 450.57 compile fails: …………………….

GCC – Fun with GCC 10, and the Kernel, NVIDIA, VMware..

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 →

VMware – Not Working with Fedora 26 – GCC 7, and Workarounds..

Adventures With Linux ™ Posted on by

UPDATE:  The vmware runtime fix shown here has not worked since version 12.5.6, and the solution is in a later article:  http://rglinuxtech.com/?p=1992 I have recently updated one crash-and-burn system to Fedora 26 (alpha/testing) and have encountered two problems with VMware and the ‘bleeding edge’ version of GCC included.. The first problem sounded very familiar, and it is a … Continue reading →

Adventures With Linux ™ Posted on by

ARM64 – Pi3 Still Very Unstable..

Adventures With Linux ™ Posted on by

I have tried the latest 4.7-next patched kernel, from https://github.com/anholt/linux/tree/bcm2837-64-next After some trials, I did manage to – just – get it to boot – after falling to an ’emergency console’, but the system is very unstable, with multiple recurring MMC errors.. …..

ARM64 – Odroid C2 U-Boot – Latest..

Adventures With Linux ™ Posted on by

I discovered there was a later version (6) of the U-boot patch for the Odroid C2, and also – after more research – found the reason for the compile error… It turns out that the GIT version (May 5, 2016) of U-boot currently needs two patches.. The first one is to provide psci_system_reset for armv8, and details … Continue reading →
