Adventures With Linux ™ Posted on by

Just updated the test system to Kernel 4.15-rc3, and the GPL issue for NVIDIA drivers has been fixed, as mentioned – vaguely – in the brief details here:  http://lkml.iu.edu/hypermail/linux/kernel/1712.1/01379.html.

Adventures With Linux ™ Posted on by

Thanks – again – to mkubecek, there is now a fix for VMware 14.0.0 and Kernel 4.15 – and details are here:   https://github.com/mkubecek/vmware-host-modules/commit/562121d7bc06 The fix involves changes to vmmon-only/linux/driver.c and vmmon-only/linux/hostif.c, and a new file: vmmon-only/include/compat_timer.h .    I have tested this on 4.15-rc1, and now vmmon compiles, and vmware loads/runs, correctly.

IA64 – An Exercise in Nostalgia..

Adventures With Linux ™ Posted on by

Ever since I spent some considerable time promoting HP’s IA64 Linux systems, way back in the early-2000’s, I have always wanted one for myself, and I recently managed to acquire an RX2600 1U server for a very reasonable price, and beef it up with some inexpensive parts from eBay.. The spec – at the moment – is … Continue reading →

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 →
