class MsdIntelRegisterIo

Defined at line 19 of file ../../src/graphics/drivers/msd-intel-gen/src/msd_intel_register_io.h

Wraps the common magma::RegisterIo so we can intercept reads and writes and perform forcewake

checks.

Public Methods

void MsdIntelRegisterIo (Owner * owner, std::unique_ptr<magma::PlatformMmio> mmio, uint32_t device_id)

Defined at line 13 of file ../../src/graphics/drivers/msd-intel-gen/src/msd_intel_register_io.cc

std::shared_ptr<ForceWakeDomain> GetForceWakeToken (ForceWakeDomain domain)

This token must be held while accessing registers in the given domain.

Note, releasing the token doesn't release the forcewake because those

are deferred.

void MsdIntelRegisterIo (std::unique_ptr<magma::PlatformMmio> mmio)

Should only be used for unit testing.
