2016-12-06mei: bus: enable non-blocking RXAlexander Usyskin1-1/+6
Enable non-blocking receive for drivers on mei bus, this allows checking for data availability by mei client drivers. This is most effective for fixed address clients, that lacks flow control. This function adds new API function mei_cldev_recv_nonblock(), it retuns -EGAIN if function will block.

2016-12-06mei: synchronize irq before initiating a reset.Tomas Winkler1-1/+7
We need to synchronize irqs before issuing reset to make sure that the clients communication is concluded and doesn't leak to the reset flow and confusing the state machine.

2016-09-27mei: stop the stall timer worker if not neededAlexander Usyskin1-0/+1
The stall timer worker checks periodically if there is a stalled i/o transaction. The issue with the current implementation is that the timer is ticking also when there is no pending i/o transaction. This patch provides a simple change that prevents rescheduling of the delayed work when there is no pending i/o.

2016-05-01mei: amthif: discard not read messagesAlexander Usyskin1-0/+2
When a message is received and amthif client is not in reading state the message is ignored and left dangling in the queue. This may happen after one of the amthif host connections is closed w/o completing the reading. Another client will pick up a wrong message on next read attempt which will lead to link reset. To prevent this the driver has to properly discard the message when amthif client is not in reading state.

2016-02-08mei: fix possible integer overflow issueTomas Winkler1-2/+2
There is a possible integer overflow following by a buffer overflow when accumulating messages coming from the FW to compose a full payload. Occurrence of wrap around has to be prevented for next message size calculation. For unsigned integer the addition overflow has occurred when the result is smaller than one of the arguments. To simplify the fix, the types of buf.size and buf_idx are set to the same width, namely size_t also to be aligned with the type of length parameter in file read/write ops.

2015-10-04debugfs: Pass bool pointer to debugfs_create_bool()Viresh Kumar1-1/+1
Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument, when all it needs is a boolean pointer. It would be better to update this API to make it accept 'bool *' instead, as that will make it more consistent and often more convenient. Over that bool takes just a byte. That required updates to all user sites as well, in the same commit updating the API. regmap core was also using debugfs_{read|write}_file_bool(), directly and variable types were updated for that to be bool as well.

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: <stable@vger.kernel.org> #3.18+ Cc: Gabriele Mazzotta <gabriele.mzt@gmail.com> 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 <gabriele.mzt@gmail.com> Signed-off-by: Alexander Usyskin <alexander.usyskin@intel.com> Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
