mei: bus: enable OS version only for SPT and newer

2017-01-11T06:43:57Z

Sending OS version for support of TPM2_ChangeEPS() is required only for SPT FW (HMB version 2.0) and newer. On older platforms the command should be just ignored by the firmware but some older platforms misbehave so it's safer to send the command only if required.

mei: bus: enable non-blocking RX

2016-12-06T10:05:46Z

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.

mei: synchronize irq before initiating a reset.

2016-12-06T10:03:22Z

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. This issue is happening during suspend/resume stress testing. Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: introduce host client uninitialized state

2016-11-17T15:37:49Z

Introduce a new host client state, MEI_FILE_UNINITIALIZED, to distinguish client objects that was unlinked, but not destroyed and can be linked again. Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: constify buffer in the write functions calls

2016-11-15T09:56:52Z

The write buffer should not by modified so make it constant. Also hitchhike some style fixes on the way in the interface and rename mei_me_write_message to mei_me_hbuf_write for consistency. Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: enable to set the internal flag for client write

2016-11-10T12:18:02Z

Prepare the client write functions to set the internal flag in message header. Carry both blocking and internal modes inside the transmit cb, and call internal bus function __mei_cl_send() with send mode bit mask. The Internal flag should be added only on messages generated by the driver. Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: stop the stall timer worker if not needed

2016-09-27T10:33:47Z

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.

mei: amthif: drop mei_amthif_read

2016-08-30T12:39:42Z

mei_amthif_read have only one difference from mei_read, it is not calling mei_read_start(). Make mei_read_start return immediately for amthif client and drop the special mei_amthif_read function. Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: use consistent naming for TX control flow credits

2016-08-30T12:39:42Z

With the introduction of the receive control flow credits prefixed with rx_ we add tx_ prefix to the variables and function used for tracking the transmit control flow credits. Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman
