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 →

NVIDIA – 418.56 Released – Kernel 5.1 Fix still Applies, with Slight Tweak..

Adventures With Linux ™ Posted on March 21, 2019 by RGMarch 21, 2019

NVIDIA have released driver 418.56, and details are here:  https://devtalk.nvidia.com/default/topic/1048767/announcements-and-news/-linux-solaris-and-freebsd-driver-418-56-long-lived-branch-release-/ This version has almost the same problems with Kernel 5.1-rc1 as 418.43, but the fix mentioned in the previous article still applies, after the fixes for ‘list_is_first‘ in   ~/kernel/common/inc/nv-list-helpers.h and ~/kernel/nvidia-uvm/uvm8_range_tree.c have been removed, as these are no longer required, and would now cause the compile to … Continue reading →

The latest version of QT5 on Fedora 27 – qt5-qtbase-5.9.6-1.fc27.x86_64 – produces a very annoying display problem in KDE’s Dolphin file manager, where the window does not resize/reformat correctly, leaving large blank areas at each side: This has been identified as a QT5 bug/regression, and a patch is available, at https://codereview.qt-project.org/#/c/233482/ I have applied this, and Dolphin … Continue reading →
