Kernel – 5.10-rc3 – VMware Still Fails, NVIDIA Still ‘Tainted’..
Kernel 5.10-rc3 is out, and details of recent changes are here: http://lkml.iu.edu/hypermail/linux/kernel/2011.1/00301.html
VMware 16 – patched – still compiles and loads OK, but runtime VM start fails:
"VMware Workstation unrecoverable error: (vcpu-0)
vcpu-0:ASSERT vmcore/lock/vmm/semaphore.c:93
A log file is available............ "
console:
.......................

There seems to have been some confusion over NVIDIA, but the ‘taint’ problem still exists on all my 5.9 and 5.10 systems. This article on the Forum provides some clarity, with a comment from an NVIDIA representative that a fix should be available around ‘mid-November’.. https://forums.developer.nvidia.com/t/455-38-and-kernel-5-9-6/159039

A tentative patch (kernel, not vmmon) for the eventfd issue can be found at https://github.com/mkubecek/kernel/commit/5bf2e09dd1be
Anyone willing to give it a try would be more than welcome.
Applied to 5.10-rc4, and VMware appears to be working OK, now.. (tested with WinXP VM) Thanks!
