Merge patch series "mei: connect to card in D3cold"
Alexander Usyskin <alexander.usyskin@intel.com> says:
When discrete graphic card enters D3cold th CSC engine is powered down.
On wakeup from the D3cold full HECI link reset is required. The driver
should detect that firmware requests link reset and initiate the link
reset flow.
In the usual flow the connect IOCTL will trigger the wake from D3cold
and corresponding link reset. The MEI driver invalidates all open
handles on link reset including the one that triggered the wake
rendering this connection unusable. To break this loop make connect
detect that it is interrupted by link reset and retry connect attempt
after reset was completed.
