MMIO -should NOT be done on your own when doing Vega kernel programming. -Instead, rely on Vega's MMIO interface and use -.Ft mmio_read<n>() -and -.Ft mmio_write<n>() -functions. Where `n` is 8 to 32 on 32-bit machines, and to 64 -on 64-bit machines. - -The -.Ft addr -argument can be either a physical address or virtual -address; however, it is recommended to use virtual addresses -for the sake of consistency. |
