User Application Kernel and Device Access Functions

Language:

The user application kernel and device access functions are:

ddi_dev_nregs(): Return the number of register sets a device has
ddi_dev_regsize(): Return the size of a device's register
ddi_devmap_segmap(), devmap_setup(): Set up a user mapping to device memory using the devmap framework
devmap_devmem_setup(): Export device memory to user space
devmap_load(): Validate memory address translations
devmap_unload(): Invalidate memory address translations
devmap_do_ctxmgt(): Perform device context switching on a mapping
devmap_set_ctx_timeout(): Set the timeout value for the context management callback
devmap_default_access(): Default driver memory access function
ddi_umem_alloc(): Allocate page-aligned kernel memory
ddi_umem_free(): Free page-aligned kernel memory
ddi_umem_lock(): Lock memory pages
ddi_umem_unlock(): Unlock memory pages
ddi_umem_iosetup(): Setup I/O requests to application memory
devmap_umem_setup(): Export kernel memory to user space
ddi_model_convert_from(): Determine data model type mismatch
