Access values of associative array whose name is passed as argument inside bash function

I've some associative arrays in a bash script which I need to pass to a function in which I need to access the keys and values as well.

declare -A gkp=( \
   ["arm64"]="ARM-64-bit" \
   ["x86"]="Intel-32-bit" \
)

fv()
{
   local entry="$1"
   echo "keys: ${!gkp[@]}"
   echo "vals: ${gkp[@]}"
   local arr="$2[@]"
   echo -e "\narr entries: ${!arr}"
}

fv $1 gkp

Output for above:

kpi: arm64 x86
kpv: ARM-64-bit Intel-32-bit

arr entries: ARM-64-bit Intel-32-bit

I could get values of array passed to function, but couldn't figure out how to print keys (i.e. "arm64" "x86") in the function. Please help.
