Public Methods

void ~Device ()

Defined at line 10 of file ../../src/graphics/magma/include/lib/magma_service/msd.cc

void MsdSetMemoryPressureLevel (MagmaMemoryPressureLevel level)

Signals the current memory pressure level for the system. May be called on any thread.

Defined at line 66 of file ../../src/graphics/magma/include/lib/magma_service/msd.h

magma_status_t MsdQuery (uint64_t id, zx::vmo * result_buffer_out, uint64_t * result_out)

Returns a value associated with the given id. On MAGMA_STATUS_OK, a given query `id` will

return either a buffer in `result_buffer_out`, or a value in `result_out`. nullptr may be

provided for whichever result parameter is not needed.

magma_status_t MsdGetIcdList (std::vector<MsdIcdInfo> * icd_info_out)

Outputs a list of ICD components.

void MsdSetPowerState (int64_t power_state, fit::callback<void (magma_status_t)> completer)

Sets the power state of the device. The given |completer| will be invoked asynchronously

when a power change is completed.

void MsdDumpStatus (uint32_t dump_flags)

Defined at line 87 of file ../../src/graphics/magma/include/lib/magma_service/msd.h

std::unique_ptr<Connection> MsdOpen (msd_client_id_t client_id)

Opens a device for the given client. Returns nullptr on failure
