Setting up the devel environment
========================================

Enabling debug mode
------------------------

# LILO configuration file
* Compile kernel with CONFIG_DYNAMIC_DEBUG=y and CONFIG_ACPI_DEBUG=y
* CONFIG_KERNEL_VERSION="-dbg"
* Add kernel parameter: addappend = "log_buf_len=16M"
* Mount debugfs
  # mount -t debugfs none /sys/kernel/debug
* Enable debug mode by adding this line:
  # echo -n 'file ec.c +p' | sudo tee /sys/kernel/debug/dynamic_debug/control
