Ok. > but I'm sure this is a problem that has been solved before. Yes! in your Kconfig select GENERIC_ALLOCATOR in your driver.c #include <linux/genalloc.h> Code is in lib/genalloc.c, if you like to take a look. Memory for MANAGING free/allocated space is NOT taken from your on-card memory! That allocator is explicitly developed for such use cases. Happy hacking!
