good question, I started poking around about this.  I know I read that AMD may 
not have been affected as much (or at all).  Have you tried applying the OS 
patches & checking?  I haven't spent a lot of time at this save one quick 
benchmark, but I did toss together quickly this bash tool to report "protected 
or not", and used RHEL 7.4.


if [ $# -lt 1 ] ; then
        printf "\n"
        printf "Spectre/Meltdown enable/disable tool\n"
        printf "\n"
        printf "usage:\n"
        printf "\n"
        printf "    spectre_meltdown  protect|unprotect|status\n"
        printf "\n"
        printf "\n"
        printf "\n"
        printf "\n"
        exit 1


if [ $ARG == "protect" ] ; then
        echo Protecting...
        echo 1 > /sys/kernel/debug/x86/pti_enabled
    echo 1 > /sys/kernel/debug/x86/ibpb_enabled
    echo 1 > /sys/kernel/debug/x86/ibrs_enabled
        exit 0

if [ $ARG == "unprotect" ] ; then
        echo Unprotecting...
        echo 0 > /sys/kernel/debug/x86/pti_enabled
    echo 0 > /sys/kernel/debug/x86/ibpb_enabled
    echo 0 > /sys/kernel/debug/x86/ibrs_enabled
        exit 0

if [ $ARG == "status" ] ; then
        PTI=`cat /sys/kernel/debug/x86/pti_enabled 2>/dev/null`
        IBPB=`cat /sys/kernel/debug/x86/ibpb_enabled 2>/dev/null`
        IBRS=`cat /sys/kernel/debug/x86/ibrs_enabled 2>/dev/null`


        if [[ ( "$PTI" == "1" ) && ( "$IBPB" == "1" ) && ( "$IBRS" == "1" ) ]] 
; then

        printf "%s\n"  "$STATUS"
        exit 0

echo Invalid argument.
exit 1

Subject: [Poweredgec-tools] any further BIOS updates for C6145?

Since the question came up on an internal chat (about updates for 
Spectre/Meltdown/etc) will the C6145 see any more firmware updates?
