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 →

NVIDIA – Possible Fix for 6.0?

Adventures With Linux ™ Posted on by

After more testing, I found a potential fix for the ‘Kernel 6.0-rc0’ compile problem.. In NVIDIA-Linux-x86_64-515.65.01/kernel/nvidia-drm/nvidia-drm-helper.c: Around Line 30: add: #include <drm/drm_framebuffer.h> And the compile completes successfully: ……………………….. ld -r -o /home/rgadsdon/NVIDIA-Linux-x86_64-515.65.01/kernel/nvidia-modeset/nv-modeset-interface.o /home/rgadsdon/NVIDIA-Linux-x86_64-515.65.01/kernel/nvidia-modeset/nvidia-modeset-linux.o /home/rgadsdon/NVIDIA-Linux-x86_64-515.65.01/kernel/nvidia-modeset/nv-kthread-q.o MODPOST /home/rgadsdon/NVIDIA-Linux-x86_64-515.65.01/kernel/Module.symvers CC [M] /home/rgadsdon/NVIDIA-Linux-x86_64-515.65.01/kernel/nvidia-drm.mod.o LD [M] /home/rgadsdon/NVIDIA-Linux-x86_64-515.65.01/kernel/nvidia-drm.ko CC [M] /home/rgadsdon/NVIDIA-Linux-x86_64-515.65.01/kernel/nvidia-modeset.mod.o LD [M] /home/rgadsdon/NVIDIA-Linux-x86_64-515.65.01/kernel/nvidia-modeset.ko CC [M] /home/rgadsdon/NVIDIA-Linux-x86_64-515.65.01/kernel/nvidia-peermem.mod.o LD [M] /home/rgadsdon/NVIDIA-Linux-x86_64-515.65.01/kernel/nvidia-peermem.ko CC [M] /home/rgadsdon/NVIDIA-Linux-x86_64-515.65.01/kernel/nvidia-uvm.mod.o … Continue reading →

Adventures With Linux ™ Posted on by

Kernel 5.17-rc1 is due out soon, and so I tested the latest (Jan 16th) Github version, to see if there were any surprises.. The latest NVIDIA driver – 510.39.01 – compiled and loaded/ran OK: …………. ld -r -o /home/rgadsdon/NVIDIA-Linux-x86_64-510.39.01/kernel/nvidia-modeset/nv-modeset-interface.o /home/rgadsdon/NVIDIA-Linux-x86_64-510.39.01/kernel/nvidia-modeset/nvidia-modeset-linux.o /home/rgadsdon/NVIDIA-Linux-x86_64-510.39.01/kernel/nvidia-modeset/nv-kthread-q.o MODPOST /home/rgadsdon/NVIDIA-Linux-x86_64-510.39.01/kernel/Module.symvers CC [M] /home/rgadsdon/NVIDIA-Linux-x86_64-510.39.01/kernel/nvidia-drm.mod.o LD [M] /home/rgadsdon/NVIDIA-Linux-x86_64-510.39.01/kernel/nvidia-drm.ko CC [M] /home/rgadsdon/NVIDIA-Linux-x86_64-510.39.01/kernel/nvidia-modeset.mod.o LD [M] /home/rgadsdon/NVIDIA-Linux-x86_64-510.39.01/kernel/nvidia-modeset.ko CC [M] … Continue reading →

Disks – Not so S.M.A.R.T. After All?

Adventures With Linux ™ Posted on by

More problems with severe disk performance degradation, but SMART still shows the disc as ‘OK’.. This has now occurred three times over the last 2 years or so, with 1TB and 2TB disks that were around 4+ years old (in continuous use..).. The contents were still accessible, but data transfer was extremely slow – around 250KiB/s to … Continue reading →

ARM64 – Pi 4 USB Problems – And a Messy Fix..

Adventures With Linux ™ Posted on by

After some delay, I finally had a ‘good’ cooling solution for my 8GB Pi4, and resumed testing.. The last Kernel version I had running on it was 5.9-rc4, and everything seemed to be working OK (including 8GB of memory recognised). I then updated to 5.11.18, and found that none of the USB ports worked: # dmesg |grep … Continue reading →

Kernel – 5.9-rc1 Released – VMware Still Broken.. NVIDIA Compile Fails..

Adventures With Linux ™ Posted on by

Kernel 5.9-rc1 is out, and brief details are here: http://lkml.iu.edu/hypermail/linux/kernel/2008.2/00223.html As expected, VMware is still broken, and fails/reboots when a VM start is attempted. Vmnet, with the latest patch, compiles OK, and there is a patch for vmmon and Kernel 5.9 available, for the Workstation 16 early-release, here: https://github.com/mkubecek/vmware-host-modules/tree/tmp/workstation-16 With regard to NVIDIA, the interim patch for … Continue reading →

VirtualBox – Latest Development Version Tests with Kernel 5.8 – Unstable..

Adventures With Linux ™ Posted on by

I have been investigating alternatives, as VMware is currently a non-starter (literally..) with Kernel 5.8.. I installed the latest VirtualBox (6.1.97 r139689) from SVN (another blast from the past…) and managed – after some messing around – to get it to compile OK on my Fedora 32 test system with Kernel 5.8 (from kernel.org..)    I had … Continue reading →

Kernel – 5.8 Released – NVIDIA OK, but VMware Runtime Causes Reboot, With No Warning..

Adventures With Linux ™ Posted on by

Kernel 5.8 is out, and details are here:   http://lkml.iu.edu/hypermail/linux/kernel/2008.0/00586.html The (patched) VMware 15.5.6  vmmon/vmnet modules compile OK, and the latest NVIDIA driver 450.57 compiles and runs OK. However….    I cannot upgrade my main systems, as the catastrophic VMware runtime reboot still occurs, as mentioned in previous articles: $ uname -a Linux rgz220 5.8.0 #2 SMP Sun Aug … Continue reading →
