Function uacpi_kernel_io_read8
uacpi_status uacpi_kernel_io_read8(uacpi_handle, uacpi_size offset, uacpi_u8 * out_value)
Description
Read/Write the IO range mapped via uacpi_kernel_io_map
at a 0-based 'offset' within the range. NOTE: The x86 architecture uses the in/out family of instructions to access the SystemIO address space. You are NOT allowed to break e.g. a 4-byte access into four 1-byte accesses. Hardware ALWAYS expects accesses to be of the exact width.
