mei: support for fixed address clients

2015-05-24T18:13:48Z

Fixed address is simplified FW client that doesn't require connection and doesn't support flow control. So it can be only one host client per fixed FW client. Fixed client access is available only for drivers on mei bus, connection from user-space is blocked. Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: add a reference from the host client to the me client

2015-05-24T18:13:10Z

Keep a pointer to associated me client in the host client object to eliminate me client searches. Check if the me client is active in the firmware by checking if its is linked on the me clients list Add accessors for the me client properties from host client.

mei: revamp client connection

2015-05-24T18:13:10Z

Simplify connect state machine by changing the logic around Connection request in progress - only check if we have a callback in relevant queue. Extract common code into mei_cl_send_connect() function Signed-off-by: Tomas Winkler Signed-off-by: Alexander Usyskin Signed-off-by: Greg Kroah-Hartman

mei: revamp client disconnection flow

2015-05-24T18:13:10Z

Split disconnected state into two parts first reception disconnect response from the firmware and second actually setting of disconnected state. Book keeping data are needed for processing and after firmware disconnected the client and are cleaned when setting the disconnected state in mei_cl_set_disconneted() function. Add mei_cl_send_disconnect to reduce code duplication. Signed-off-by: Tomas Winkler Signed-off-by: Alexander Usyskin Signed-off-by: Greg Kroah-Hartman

mei: use mei_cl_is_connected consistently

2015-04-03T14:18:56Z

Replace open coded check for cl->state !=/== MEI_FILE_CONNECTED with mei_cl_is_connected function. Note that cl->state != MEI_FILE_CONNECTED is not the same as cl->state == MEI_FILE_DISCONNECTED Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: allow read concurrency

2015-03-02T03:37:00Z

Replace clunky read state machine with read stack implemented as per client read list, this is important mostly for mei drivers with unsolicited reads Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: simplify io callback disposal

2015-03-02T03:37:00Z

Simplify disposal of io callback by removing the callback implicitly from its lookup list inside mei_io_cb_free Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: use only one buffer in callback

2015-03-02T03:37:00Z

The callback structure is used exclusively for reading or writing therefore there is no reason to hold both response and request buffers in the callback structure Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: iamthif: use regular client read functions

2015-03-02T03:37:00Z

Reduce code duplication in amthif by reusing regular client read functions. The change also removes the need for amthif own buffering Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: iamthif: send flow control as a regular client

2015-03-02T03:37:00Z

Reuse common client mechanism for sending flow control hbm message. Add new function mei_amthif_read_start similar to mei_cl_read_start that puts control flow request onto the control write queue and drop mei_amthif_irq_read function Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman
