2013-02-06mei: rename to mei_host_buffer_is_empty to hbuf_is_readyTomas Winkler1-4/+4
we rename the mei_host_buffer_is_empty to keep naming convention of hbuf and also make the query more generic to be correct also for other under laying hardware Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-02-06mei: separate compilation of the ME hardware specificsTomas Winkler1-3/+3
We add struct mei_hw_ops to virtualize access to hw specific configurations. This allows us to separate the compilation of the ME interface from the ME hardware specifics Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-18Merge 3.8-rc4 into char-misc-nextGreg Kroah-Hartman1-3/+3
This brings in all of the mei and other fixes that are needed to continue development in this branch. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-09mei: move MEI_IAMTHIF_IDLE to amthif host init functionTomas Winkler1-0/+2
Since the amthif state is not examined until amthif is connected we can safely move it to the amthif host init function Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-09mei: normalize me host client linking routinesTomas Winkler1-16/+26
In order we can use the same code pattern for in-kernel and user space host clients we replace mei_cl_link_to_me with mei_cl_link function. We then have to keep me client lookupout of the new link function. The unlinking cannot be yet symetric due to amthif connection handling Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-09mei: rename remaining amthi strings to amthifTomas Winkler1-31/+31

2013-01-09mei: rename interface to hw-meTomas Winkler1-1/+1
Rename hw-me.h to hw-me-regs.h as this file contains only register definitions. Files hw-me.[ch] now contains ME hw dependant functionality Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-09mei: fix client functions namesTomas Winkler1-4/+5
Use common prefix for function names: mei_cl_ - for host clients mei_me_ - for me clients mei_io_ - for io callback functions Because mei_cl holds mei_device back pointer we can also drop the dev argument from the client functions add client.h header to export the clients API Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-09mei: add new hbm.h header to export hbm protocolTomas Winkler1-0/+1

2013-01-07mei: add common prefix to hbm functionTomas Winkler1-3/+4
1. use mei_hbm_ for basic host bus message function 2. use mei_hbm_cl prefix for host bus messages that operation on behalf of a client Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-07mei: use structured buffer for the write bufferTomas Winkler1-13/+12
We can drop useless castings and use proper types. We remove the casting in mei_hbm_hdr function and add new function mei_hbm_stop_request_prepare that utilize the new structure Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-07mei: include local headers after the system onesTomas Winkler1-2/+1
first include linux/mei.h then only local headers to avoid possible false dependencies Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-07mei: use unified format for printing mei message headerTomas Winkler1-2/+1
Introduce MEI_HDR_FMT and MEI_HDR_PRM macros. Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-07mei: drop redundant length parameter from mei_write_message functionTomas Winkler1-4/+2
The length is already part of the message header and it is validated before the function call Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-07mei: fix mismatch in mutex unlock-lock in mei_amthif_read()Alexey Khoroshilov1-3/+3
Users of mei_amthif_read() expect it leaves dev->device_lock held, while there is a path where mei_amthif_read() unlocks device_lock and returns -ERESTARTSYS. The patch move code locking device_lock back before the return. Found by Linux Driver Verification project (linuxtesting.org).

2012-11-22mei: streamline amthif write complete functionTomas Winkler1-54/+44
Rename the function mei_amthif_irq_process_completed to mei_amthif_irq_write_complete Remove cl from the parameter list as it can be extracted from cb block. Extract the common flow from if statements and document the logic properly Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-11-16mei: use link and unlink terms for connecting ME and HOST clientTomas Winkler1-2/+2

2012-11-16mei: use type struct mei_cl *cl instead of void in struct mei_cbTomas Winkler1-10/+4
We can use correct type 'struct mei_cl' instead of 'void *' for file_private in the struct mei_cb as there is no other type assigned to this member of the structure We rename the member from file_private to cl Remove about 10 lines of declarations of temporary variables used for type casting Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-11-01mei: move amthif specific code from mei_write to mei_amthif_writeTomas Winkler1-3/+36
For sake of amthif consolidation move amthif specific code from mei_write to mei_amthif_write The original mei_amthif_write to mei_amthif_send_cmd as this function deals with sending single command while mei_amthif_write is interface function called from the main driver which in turns calls mei_amthif_send_cmd Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
