=== Tests ===
==== get_power_limit Test ====
* Test
AMDGPU_PCI_ADDR=`lspci -nn | grep "VGA\|Display" | cut -d " " -f 1`
AMDGPU_HWMON=`ls -la /sys/class/hwmon | grep $AMDGPU_PCI_ADDR | cut -d " " -f 10`
HWMON_DIR=/sys/class/hwmon/${AMDGPU_HWMON}
lspci -nn | grep "VGA\|Display" ; \
echo "=== power1 cap ===" ; cat $HWMON_DIR/power1_cap ; \
echo "=== power1 cap max ===" ; cat $HWMON_DIR/power1_cap_max ; \
echo "=== power1 cap def ===" ; cat $HWMON_DIR/power1_cap_default
