Implementations

impl BrcmstbGisb

pub fn new(offsets: GisbOffsets) -> Self

Creates a new instance.

pub fn set_big_endian(&mut self, big_endian: bool)

Sets big endian.

pub fn set_master_names<I: IntoIterator<Item = String>>(&mut self, names: I)

Replaces the bus-master name table.

Entry i names the hardware master whose ID reads back as i from arb_err_cap_master/arb_bp_cap_master. Tables are generation-specific; they must be supplied by platform code (DeviceTree/board support), mirroring Linux’s gisb_master_names_*[] per-SoC tables.

pub fn add_master_name(&mut self, name: String)

Appends one entry to the master-name table (see Self::set_master_names). Entries are appended in order, so this positions the name at the next free master-ID slot.

pub fn master_name(&self, master: Option<u32>) -> String

Resolves a captured master ID to its human-readable name.

• None (generation without a master register) => "none";
• ID present in the configured table => the platform-provided name;
• otherwise => "master<N>", still more useful than an empty string.

fn read_gisb(&self, offset: usize) -> u32

Reads gisb.

fn write_gisb(&self, offset: usize, val: u32)

Writes gisb.

pub fn get_timeout(&self) -> u32

Returns timeout.

pub fn set_timeout(&self, val: u32)

Sets timeout.

pub fn format_error(&self, info: &GisbErrorInfo) -> String

Formats a captured GISB error into a one-line human-readable report, e.g. gisb timeout write addr=0x00000000deadbeef master=ethsw. This is the string platform IRQ handlers should emit in their logs.

pub fn handle_timeout_irq(&self) -> Option<GisbErrorInfo>

Handles timeout irq.

pub fn handle_bp_irq(&self) -> Option<GisbErrorInfo>

Handles bp irq.
