PowerBlock ko with new Moode Audio Version Need a fix on poverblockservice KERNEL 6.6

[Boum.01]

hello
When upgarding to last version of Moode Audio, from 8.3.9 (32-bit Bullseye) to 9.1.3 (64-bit Bookworm)., the powerBlock service didn't work anymore (due to the new kernel 6.6 that avoid sysfs use and force gpiotools instead).
I tried a fix on your last RPI5 update to make it work with RPI4 running a 6.6 Kernel (or newer).
1 create a checkkernel function.
2 use this foncton if mode = 0 instead of turning Gpiotools indicator to to false

# Source code

 Checkkernel(){
# check the kernel version if GT 6.6 Use Gpiotool event if not runing on a RP5
  CURRENT_KERNEL_VERSION=$(uname --kernel-release | cut --delimiter="." --fields=1-2)
  CURRENT_KERNEL_MAJOR_VERSION=$(echo "$CURRENT_KERNEL_VERSION" | cut --delimiter="." --fields=1)
  CURRENT_KERNEL_MINOR_VERSION=$(echo "$CURRENT_KERNEL_VERSION" | cut --delimiter="." --fields=2)
  ALLOWED_KERNEL_VERSION="6.6"
  ALLOWED_KERNEL_MAJOR_VERSION=$(echo $ALLOWED_KERNEL_VERSION | cut --delimiter="." --fields=1)
  ALLOWED_KERNEL_MINOR_VERSION=$(echo $ALLOWED_KERNEL_VERSION | cut --delimiter="." --fields=2)
  if [ "$CURRENT_KERNEL_MAJOR_VERSION" -ge "$ALLOWED_KERNEL_MAJOR_VERSION" ]; then
     if [ "$CURRENT_KERNEL_MINOR_VERSION" -lt "$ALLOWED_KERNEL_MINOR_VERSION" ]; then
        echo " Kernel $CURRENT_KERNEL_VERSION gpiotools not supported, please use sysfs." | write_log
        GPIO_TOOLS_AVAILABLE=false  # gpioset is not working as expected. Therefore, use sysfs approach for RPi models < 5.
     else
        echo " Kernel $CURRENT_KERNEL_VERSION please use gpiotools." | write_log
        GPIO_TOOLS_AVAILABLE=true  # gpioset is working as expected.
     fi
  else
     echo "Kernel $CURRENT_KERNEL_VERSION  Gpiotools not supported please use sysfs." | write_log
     GPIO_TOOLS_AVAILABLE=false  # gpioset is not working as expected. Therefore, use sysfs approach for RPi models < 5.
  fi
}


# Check for RPi model
model=$(cat /proc/cpuinfo | grep 'Model' | awk '{print $5}')
echo "Detected RPi model $model".

# Determine Raspberry Pi GPIO access chip
# chip=4 for RPi5, chip=0 for older models
if [ $GPIO_TOOLS_AVAILABLE ] && [ "$model" -gt 4 ]; then
  chip=4
else
  chip=0
 Checkkernel
fi

@Boum-01 Thanks! I will use this to further improve the driver.
