Oliver, In the glorious tradition of completely untested patches, I can say this shows very encouraging results ! Sorry for testing this only today but I've been very busy with other tasks. I applied the provided patch on Kernel v2.6.28. I get autosuspend quite a lot of time and resume is working fine. Haven't seen any deadlock for the moment. We will stress it a little bit using automatic scripts and see what we can get out of it. Would you like me to send you some logs/reports or do some more tests? That would be very interesting to have such a feature in future kernels. Thanks ! Regards, Nicolas. -----Original Message----- From: Oliver Neukum [mailto:oliver@xxxxxxxxxx] Sent: 03 May 2009 14:48 To: Nicolas Chevillot; David Brownell; linux-usb@xxxxxxxxxxxxxxx; Carl Nordbeck Subject: [rft]aggressive autosuspend for cdc-ether Hi, in the glorious tradition of completely untested patches, here comes a patch implementing autosuspend for always online connections using cdc-ether.
