To ensure the safety of this mitigation, the kernel must ensure that the

safe return sequence is itself free from attacker interference. In Zen3
|

and Zen4, this is accomplished by creating a BTB alias between the
|

untraining function srso_untrain_ret_alias() and the safe return
|

function srso_safe_ret_alias() which results in evicting a potentially

untraining function srso_alias_untrain_ret() and the safe return

function srso_alias_safe_ret() which results in evicting a potentially

poisoned BTB entry and using that safe one for all function returns.

In older Zen1 and Zen2, this is accomplished using a reinterpretation

The AD74412R and AD74413R are quad-channel software configurable input/output
|
||||
solutions for building and process control applications. They contain
|
||||
functionality for analog output, analog input, digital input, resistance
|
||||
temperature detector, and thermocouple measurements integrated
|
||||
into a single chip solution with an SPI interface.
|
||||
The devices feature a 16-bit ADC and four configurable 13-bit DACs to provide
|
||||
four configurable input/output channels and a suite of diagnostic functions.
|
||||
The AD74413R differentiates itself from the AD74412R by being HART-compatible.
