VMware – Convoluted Guest Freeze Fix…

Adventures With Linux ™ Posted on January 20, 2022 by RGJanuary 20, 2022

I had been struggling for some considerable time with guest (Win10) performance issues with VMware – including application (Photoshop CS6) ‘freezing’ for a time, and overall very sluggish responses.. I had found several articles that suggested cause/effect/fix for this, but none really worked.. I made changes to control khugepaged: …………………….. [root@rglinux820 ~]$ echo never | tee /sys/kernel/mm/transparent_hugepage/defrag … Continue reading →

Compiler – Fun with CLANG – Kernel, NVIDIA, and VMware…

Adventures With Linux ™ Posted on March 27, 2021 by RGMarch 30, 2021

I have been carrying out some preliminary tests to see how feasible it is to compile the Linux Kernel, and NVIDIA drivers, and VMware, using the ‘alternative’ to GCC – CLANG.. The kernel compile is relatively easy, and well documented: # make CC=clang HOSTCC=clang -j8 (for a 4-core system) The compile seems to be slower than GCC, … Continue reading →

VMware – Fix for Kernel 5.8 Available..

Adventures With Linux ™ Posted on September 5, 2020 by RGSeptember 5, 2020

With thanks to huyz for the notification – there is now a patch from baryonix available for VMware 15.5.6 and Kernel 5.8..    The patch is available here:  https://github.com/baryonix/vmware-host-modules/tree/fixes-for-5.8 I have – briefly – tested this with Kernel 5.8.5, and it was successful..     As the usual # vmware and # vmware-modconfig still segfault, then vmmon/vmnet have to be … Continue reading →

VMware – Kernel 5.8 is a Serious Problem?

Adventures With Linux ™ Posted on July 19, 2020 by RGJuly 19, 2020

Since the release of Kernel 5.8-rc1, any attempt I made to run a VMware client on that host system has failed catastrophically. ( see http://rglinuxtech.com/?p=2753 ) and the problem still persists, with 5.8-rc6. I had posted brief details of the issue on the VMware forum some weeks ago, but there has been no useful response. https://communities.vmware.com/thread/638457 I … Continue reading →

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

Adventures With Linux ™ Posted on February 21, 2020 by RGFebruary 21, 2020

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 – 15.5.1 Released – Just Runtime Client Security Fixes?

Adventures With Linux ™ Posted on November 13, 2019 by RGNovember 13, 2019

VMware have released version 15.5.1, and details are here:  https://docs.vmware.com/en/VMware-Workstation-Pro/15.5/rn/VMware-Workstation-1551-Pro-Release-Notes.html The Linux-kernel-related stuff appears to be unchanged, and compiles (with several warnings..) with Kernel 5.3 (tested with 5.3.11).    I got some odd behaviour (shared folders becoming disabled?) when running this unpatched version, and so applied the patched 15.5.0 vmmon/vmnet, which seems to work better.. Robert Gadsdon.    November … Continue reading →

Compiler – GCC 9 – First Impressions..

Adventures With Linux ™ Posted on February 22, 2019 by RGFebruary 22, 2019

Just updated to the pre-release Fedora 30 (Rawhide) on the test system, and tried out the new version of GCC: $ gcc –version gcc (GCC) 9.0.1 20190209 (Red Hat 9.0.1-0.4) Kernel 5.0-rc7 compiled successfully, and runs OK.    As expected, there were quite a lot of compiler ‘warnings’: …………………..
