MST Behavior on BDW

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Dave,

 

The following behavior is observed on BDW for MST using drm-nightly kernel:

1.       Connected boot: Display comes up on MST panel but the system is driven to low graphics mode (command line), i.e. UI doesn’t come up.

2.       Hot plug: No display on MST panel.

 

My top of the tree for drm-nightly is:
Commit ID: 17874a0bd04949ab460431e6017860ab98e0e4d2

Author: Ville Syrjälä ville.syrjala@xxxxxxxxxxxxxxx

drm-intel-nightly: 2015y-11m-26d-16h-57m-42s UTC integration manifest

 

Request you to kindly confirm this behavior for MST on BDW.

 

P.S: We are observing the same behavior after applying the reorganization of DP HPD handling patches.

 

Thanks and Regards,

Shubhangi Shrivastava.
