KBlockInfo

Size : 0x8 bytes

Offset	Type	Description
0x0	u32	Pointer to memory section start in FCRAM using kernel vmem addresses
0x4	u32	Page count

KBlockInfo objects start with the FS KProcess on the kernel heap and continue in order. Each KProcess gets 3 or more KBlockInfo objects for (in order) .text pointer and page count, .rodata pointer and page count, and .data pointer and page count. Apps that require more space than is available in a given block will get multiple KBlockInfo objects for each section to split it up into open spaces.

When KBlockInfo data is destroyed, the page for page reference counts for each page in the block are updated. At the beginning of base memory, the first 0x20000 bytes make up 0x8000 words. Each word represents the reference count for 1 page of FCRAM, in order from beginning to end. As the pages are checked for freeing up, each reference count is decremented and the pages with a reference count of 0 are released.
