mei: fix ssize_t to int assignment in read and write ops.

2018-07-12T14:23:19+00:00

Use ssize_t for rets variables in mei_write(), mei_read(), and
mei_cl_write() as well as change the return type of mei_cl_write()
to ssize_t, to prevent assignment of possible 64bit size_t
to int 32 bit variable.

As by product also eliminate warning
drivers/misc/mei/client.c:1702:11: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]

mei: drop amthif internal client

2017-04-08T15:38:25+00:00

AMTHIF has special support in the mei drive, it handles multiplexing
multiple user space connection above single me client connection.
Since there is no additional addressing information there is a strict
requirement on the traffic order on each connection and on the "read
after write" order within the connection. This creates a lot of
complexity mostly because the other client types do not necessarily fall
under the same restriction.    After carefully studying the use of the
AMTHIF client, we came to conclusion that the multiplexing is not really
utilized by any application and we may safely remove that support and
significantly simplify the driver.

mei: revamp io list cleanup function.

2017-01-31T10:07:43+00:00

Specify in function names by which object is the io list filtered:
cl for a client and fp for file descriptor.
In that course a code duplication is resolved by dropping
mei_cl_read_cb_flush and mei_clear_list and using
mei_io_list_free_fp function.

mei: replace callback structures used as list head by list_head

2017-01-31T10:07:43+00:00

mei_dev structure used struct mei_cl_cb type variables as for holding
callbacks list heads.  Replace them by the actual struct list_head
as there is no other info that is handled. This slims down
the mei_dev structure and mostly streamline the code.

mei: enable to set the internal flag for client write

2016-11-10T12:18:02+00:00

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.

mei: add wrapper for queuing control commands.

2016-08-30T12:39:42+00:00

Enclose the boiler plate code of allocating a control/hbm command cb
and enqueueing it onto ctrl_wr.list in a convenient wrapper
mei_cl_enqueue_ctrl_wr_cb().

This is a preparatory patch for enabling consecutive reads.
