File src/commonlib/include/commonlib/coreboot_tables.h:
struct lb_smmstorev2 {
uint32_t tag;
uint32_t size;
uint32_t num_blocks; /* Number of writeable blocks in SMM */
uint32_t block_size; /* Size of a block in byte. Default: 64 KiB */
uint32_t mmap_addr; /* MMIO address of the store for read only access */
uint32_t com_buffer; /* Physical address of the communication buffer */
uint32_t com_buffer_size; /* Size of the communication buffer in bytes */
uint8_t apm_cmd; /* The command byte to write to the APM I/O port */
uint8_t unused[3]; /* Set to zero */
};
I don't see an APM call right now, I guess not.
Not for now, but as a future idea it is doable. In fact, SMMSTORE is for payload and/or OS use right?
