Kernel – 4.14.10 Still breaks NVIDIA!

Adventures With Linux ™ Posted on by

Just updated the test system to Kernel 4.14.10, and was ‘somewhat dismayed‘ – to put it politely – that the NVIDIA breakage introduced in 4.14.9 is still there! ………… /home/rgadsdon/kernel/NVIDIA-Linux-x86_64-384.98/kernel/nvidia-uvm/uvm8_va_block.c: In function ‘block_cpu_fault_locked’: /usr/src/linux-4.14.10/arch/x86/include/asm/processor.h:826:39: error: implicit declaration of function ‘task_stack_page’; did you mean ‘task_stack_vm_area’?

KERNEL – 4.14.9 Breaks NVIDIA – and a Fix..

Adventures With Linux ™ Posted on by

Just updated to Kernel 4.14.9, and normally this should not be anything to cause concern, but this time there has been a significant code change made, that has broken NVIDIA (384.98): ………………… /home/rgadsdon/kernel/NVIDIA-Linux-x86_64-384.98/kernel/nvidia-uvm/uvm8_va_block.c: In function ‘block_cpu_fault_locked’: /usr/src/linux-4.14.9/arch/x86/include/asm/processor.h:826:39: error: implicit declaration of function ‘task_stack_page’; did you mean ‘task_stack_vm_area’?

VMware – 14.1.0 released – OK with Kernel 4.14, Still Broken with 4.15, and a Nasty Hack to Fix..

Adventures With Linux ™ Posted on by

Just updated to VMware Workstation 14.1.0, and release notes are here:  https://docs.vmware.com/en/VMware-Workstation-Pro/14.0.0/rn/workstation-141-release-notes.html This now works OK with Kernel 4.14 (tested with 4.14.8) but vmmon is still broken with Kernel 4.15 (tested with 4.15-rc4): ……………. /tmp/modconfig-04hK9s/vmmon-only/linux/hostif.c: In function ‘HostIF_InitUptime’: /tmp/modconfig-04hK9s/vmmon-only/linux/hostif.c:1770:4: error: implicit declaration of function ‘init_timer’; did you mean ‘init_timers’?

VMware – 12.5.8 Released – Still Incompatible..

Adventures With Linux ™ Posted on by

There has been a new release of Workstation 12.5 – 12.5.8 – and the – rather vague – release notes are here:  https://docs.vmware.com/en/VMware-Workstation-Pro/12.0/rn/workstation-1258-release-notes.html I tested this with a ‘clean’ install on my cash-and-burn system, and basically, it suffers from the same compatibility problems as 12.5.7.    GCC7, Fedora 26/27, and Kernel 14.x all cause it to fail. # … Continue reading →

VMware – 14.0.0 ‘Fail to open Executable’ – More Info..

Adventures With Linux ™ Posted on by

When running VMware 14 (14.0.0) from the command line, I noticed the following message: $ vmware Fail to open executable: No such file or directory Further research suggested that this ‘missing’ item was in fact /usr/lib/vmware/lib/libvmware-unity-helper.so/libvmware-unity-helper.so, which is indeed not included with VMware 14.0.0.. I found a copy of this in an old backup, and tried to … Continue reading →

NVIDIA – Still no 4.11 Solution, but a ‘Good’ Patch for Old Version..

Adventures With Linux ™ Posted on by

Kernel 4.11 ‘final’ has been delayed for a week, and -rc8 has been released..     4.11-patched VMware 12.5.5 is OK, but there is still only a ‘Bad’ (illegal licence modification) patch for the latest NVIDIA driver..   (see https://devtalk.nvidia.com/default/topic/1002820/linux/-patch-381-09-kernel-4-11-rc5/ ) But, if you have an older card, there is a valid patch for driver 340.102 – which does not … Continue reading →

Kernel – 4.11-rc1 and BTRFS – a Warning..?

Adventures With Linux ™ Posted on by

I encountered a catastrophic problem with btrfs formatted system disk partition corruption, shortly after updating a test system to Kernel 4.11-rc1. To put this in context, this may be an isolated incident, and I have not seen problems – so far – mentioned elsewhere..    But.. there a quite a lot of BTRFS changes on 4.11, and – … 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 →

VMware – Patch for Kernel 4.11 Support..

Adventures With Linux ™ Posted on by

Thanks to Virgo, there are now patches for vmnet and vmmon with Kernel 4.11 (see his comments under the earlier article).    These are incremental patches, for application to VMware 12.5.2 code already patched for Kernel 4.9/4.10 support.. Links are here:   http://pastebin.com/McqmUf0u     and    http://pastebin.com/yjbDHiSX I have modified these (adding appropriate #if LINUX_VERSION_CODE…… #endif statements) to be backward-compatible with … Continue reading →
