| H A D | pci-me.c | 67de6bf1 Thu Jun 29 01:40:02 CDT 2017 Alexander Usyskin <alexander.usyskin@intel.com> mei: me: enable asynchronous probing
On some platforms, currently Broxton, Apollo Lake and Kaby Lake,
ME FW may be busy with internal bookkeeping and answering late
to the start message.
As a mitigation, the driver requests for a synchronous probing
to prevent stalling of the overall boot process. For example,
on a Apollo Lake platform the overall boot time has reduced from
~0.9 to ~0.6 seconds on average.
