Nvidia drivers POPCNT SSE 4.2



​Hi,

Is anyone running an Nvidia card on a CPU that does not support POPCNT?

I have been reading about Blue Screens of Death being experience by Windows users due to Nvidia drivers not supporting CPUs which do not have support for POPCNT.

I am wondering if this issue will affect Linux users too?. Particularly those who use the Nvidia proprietary drivers. I do not know if Nouveau drivers will require POPCNT.

To check for POPCNT support in Linux I used:

$ grep popcnt /proc/cpuinfo

and/or

$ lscpu | grep popcnt

For my CPU it returned the relevant values of "sse4_2" "popcnt".


George.
