Hi,
This series will introduce support for using PIO for commands (immediate
commands) instead of CORB while retaining the use of RIRB for unsolicited
responses (notifications).
This mode of operation is the recommended one for Lunar Lake family.
The series adds support for the PIO mode for SOF and the 'legacy' HDA
stack to make sure that they will work correctly when Lunar Lake is available
for consumers.
Regards,
Peter
