Dear Eric,
Have you tried the function
alloc_bootmem_low() early in the boot process in main.c ?
Yes, it sounds reasonable. With this function, I can reserve a large amount
of buffer during booting time. But I think maybe it will be better to put
this function in the device driver and when booting time, the driver is
loaded and the memory part is reserved for later use, right?
Thanks for your idea so much. It's really helpful.
Regards
Ming
