Kernel 6.17-rc1 is due out in a weeks time, but I tried the latest GIT version from https://github.com/torvalds/linux to see if there will be any ‘surprises’.. Of course, there are many changes still to come.. VMware 17.6.4 with all the kernel 6.15 and 6.16 patches compiles and runs OK, but the latest NVIDIA fails to compile ( … Continue reading →
Firstly – my apologies for late response to some messages – this (12-year-old) website has been experiencing some issues, and really needs to be updated/rehosted… I am travelling, away from my main systems, and only have a laptop to test with.. I have been testing the latest VMware Workstation releases from Broadcom – 17.6 and 17.6.1 – … Continue reading →
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 →
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 →
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 →
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 →
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 →
After running kernel 5.12-rc1 for short time, it crashed: ……………………………. usb 1-1.1.1.5: USB disconnect, device number 11 usb 1-1.1.1.5.4: USB disconnect, device number 12 cp210x ttyUSB0: cp210x converter now disconnected from ttyUSB0 BUG: kernel NULL pointer dereference, address: 0000000000000278 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) – not-present page PGD 0 P4D 0 Oops: 0000 … Continue reading →
I have been testing Fedora 33 pre-release, and on x86_64 it seems relatively stable (usual caveats…) but on arm64 systems (Odroid N2 and Pi4) I found that after compiling a new kernel (5.8.3), the system booted, but login was impossible, and screen output was missing (uart/console was OK). Kernels compiled with Fedora 32 all booted OK, and … Continue reading →
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 →
