Implementations

impl QcomSscBlockBus

pub fn new() -> Self

Creates a new instance.

pub fn init_halt_regs(&mut self, base: usize)

Initializes halt regs.

pub fn init_config_regs(&mut self, config0_base: usize, config1_base: usize)

Initializes config regs.

fn ensure_mapped(&self) -> Result<(), BusError>

Ensures every MMIO region (halt, config0, config1) has been mapped by platform code before any register access.

Accessing an unmapped MmioRegion would trip its internal assertions (kernel panic); failing early with BusError::InitFailed turns a hard crash into a clean driver-registration failure instead.

fn bus_init(&self) -> Result<(), BusError>

Performs the bus init operation.

fn bus_deinit(&self) -> Result<(), BusError>

Performs the bus deinit operation.

The safety clamps are always applied, even when the halt handshake times out; the timeout is reported through the returned error.

pub fn add_child(&mut self, child: BusChild)

Performs the add child operation.

Trait Implementations

impl BusDriver for QcomSscBlockBus

fn name(&self) -> &str

fn compatible(&self) -> &[&str]

Performs the compatible operation.

fn init(&mut self, base: usize) -> Result<(), BusError>

fn read_reg(&self, offset: usize) -> Result<u32, BusError>

Reads reg.

fn write_reg(&mut self, offset: usize, value: u32) -> Result<(), BusError>

Writes reg.

fn children(&self) -> Vec<BusChild>

Performs the children operation.

fn as_firewall(&self) -> Option<&dyn FirewallController>

Returns the optional [FirewallController] capability, if any.

fn probe(&self) -> bool

Returns true if the driver believes the hardware is present.

fn suspend(&mut self) -> Result<(), BusError>

Performs the suspend operation.

fn resume(&mut self) -> Result<(), BusError>

Performs the resume operation.
