Hi,
I am writing a LKM that contains a huge constant array of data that is used
as firmware for a PCI card that is connected to the system where the LKM is
loaded.
The module_init function writes the constant data array into the PCI card's RAM
and triggers
a CPU on that card to jump to the firmware code. This works fine.
But after doing so, the firmware data is still wasting kernel memory on the
host system
and is not used anymore.
How can I free that memory ? Is there a better way to handle that data ?
Currently I have a global variable in my module code:
unsigned char firmware[] = { ..., .... ,.... about 1.4 Meg, ...}
The firmware data (about 1.4 Meg) must be linked with the LKM.
Any idea ?
