* mei: revamp hbm state machineTomas Winkler2013-04-191-13/+40
| | | | | | | | | | | | | | | | 1. Rename init_clients_state to hbm_state and use MEI_HBM_ prefix for HBM states 2. Remove recvd_msg and use hbm state for synchronizing hbm protocol has successful start. We can wake up the hbm event from start response handler and remove the hack from the interrupt thread 3. mei_hbm_start_wait function encapsulate start completion waiting Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* mei: notify about the reset in error levelTomas Winkler2013-04-081-12/+9
| | | | | | | | Display errors causing device reset using dev_err and not dev_dbg also change messages text to something more concise Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* mei: move me client storage allocation to hbm.cTomas Winkler2013-01-081-1/+38
| | | | | | | | rename function to mei_me_cl_allocate to match the current names convention: mei_hbm_me_cl_allocate Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* mei: rename interface to hw-meTomas Winkler2013-01-081-1/+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>
* mei: add new hbm.h header to export hbm protocolTomas Winkler2013-01-081-0/+1
| | | | | | | | hbm.h provides access host bus messaging functionality for other MEI layers Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* mei: move hbm responses from interrupt.c to hbm.cTomas Winkler2013-01-071-3/+186
| | | | | | | | | 1. Add common prefix mei_hbm_ to all handlers and made them static 2. Drop now useless function same_flow_addr Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* mei: add common prefix to hbm functionTomas Winkler2013-01-071-24/+32
| | | | | | | | | 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>
* mei: use structured buffer for the write bufferTomas Winkler2013-01-071-66/+68
| | | | | | | | | | 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>
* mei: simplify preparing client host bus messagesTomas Winkler2013-01-071-56/+54
| | | | | | | | | | Define a new parent type mei_hbm_cl_cmd for hbm commands that are sent on behalf of specific ME client. This allows us compacting boilerplate code via mei_hbm_cl_hdr function Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* mei: move host bus message handling to hbm.cTomas Winkler2013-01-071-0/+440
for sake of more layered design we move host bus message handling to the new hbm.c file Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
