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: replace check for connection instead of transitioning

2015-04-03T14:18:56Z

The function mei_cl_is_transitioning is just opposite of mei_cl_is_connected. What we actually wanted to check is if we lost connection so we can discard the check for transition and check for 'not connected' Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: fix regression on NFC connection

2015-03-25T10:36:37Z

In mei_host_client_init function we enable the all internal connected clients including NFC. This is done before we set the device to enabled state and let userspace call open. We need to check only for MEI_FILE_CONNECTED in mei_cl_is_connected in order to enable the communication with the clients before MEI_DEV_ENABLED is set.

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: add mei_cl_alloc_linked function

2015-03-02T03:37:00Z

Add convenient wrapper mei_cl_alloc_linked to simplify error handling Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: always initialize the callback with the intended operation type

2015-03-02T03:37:00Z

We set the operation type at initialization time as each cb is used only for a single type of operation As a byproduct we add a convenient wrapper for allocating cb with the data buffer. 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
