amdgpu/pm: Create shared array of power profile name strings
== Description ==
All the power profile modes use the same strings (or a subset of)
Creating a public array of the strings will allow sharing rather than
duplicating for each chip
First patch only implements change for navi10, followup with other chips
== Changes ==
Create a declaration of the public array in kgd_pp_interface.h
Define the public array in amdgpu_pm.c
Modify the implementaiton of navi10_get_power_profile_mode to use new array
== Test ==
LOGFILE=pp_profile_strings.test.log
AMDGPU_PCI_ADDR=`lspci -nn | grep "VGA\|Display" | cut -d " " -f 1`
AMDGPU_HWMON=`ls -la /sys/class/hwmon | grep $AMDGPU_PCI_ADDR | awk '{print $9}'`
HWMON_DIR=/sys/class/hwmon/${AMDGPU_HWMON}
lspci -nn | grep "VGA\|Display" > $LOGFILE
FILES="pp_power_profile_mode "
for f in $FILES
do
echo === $f === >> $LOGFILE
cat $HWMON_DIR/device/$f >> $LOGFILE
done
cat $LOGFILE
