mei: me: wait for power gating exit confirmation

2015-07-04T03:02:29Z

[ Upstream commit 3dc196eae1db548f05e53e5875ff87b8ff79f249 ] Fix the hbm power gating state machine so it will wait till it receives confirmation interrupt for the PG_ISOLATION_EXIT message. In process of the suspend flow the devices first have to exit from the power gating state (runtime pm resume). If we do not handle the confirmation interrupt after sending PG_ISOLATION_EXIT message, we may receive it already after the suspend flow has changed the device state and interrupt will be interpreted as a spurious event, consequently link reset will be invoked which will prevent the device from completing the suspend flow kernel: [6603] mei_reset:136: mei_me 0000:00:16.0: powering down: end of reset kernel: [476] mei_me_irq_thread_handler:643: mei_me 0000:00:16.0: function called after ISR to handle the interrupt processing. kernel: mei_me 0000:00:16.0: FW not ready: resetting Cc: #3.18+ Cc: Gabriele Mazzotta Link: https://bugzilla.kernel.org/show_bug.cgi?id=86241 Link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=770397 Tested-by: Gabriele Mazzotta Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin

mei: revamp connect and disconnect response handling

2014-09-24T05:57:48Z

Both responses have same flow only the client status update is different. We introduce handler mei_hbm_cl_res() that handles both responses Also we use per client wait queue (cl->wait) rather then global dev->wait_recvd_msg Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

When handling dynamic clients there might be a race scenario in which two me clients with the same me address would be linked in the me clients list, therefore we need to search by both uuid and me address. Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman
