mei: move host_clients_map cleanup to device init

2013-10-20T02:53:46+00:00

Move host_clients_map cleanup from host client init to device init.

This fixes bug where we cleaned up the bitmask that servers as pool for
host client ids while file descriptors are kept open during suspend.
On resume a new connection will be assigned id that is already taken
by opened file descriptor. Consequently read/write will fail due to
mismatched book keeping.

mei: revamp open handler counts

2013-10-03T23:01:16+00:00

Make open counter to be incremented and decremented
from mei_cl_link and mei_cl_unlik function respectively

Nfc was assuming symmetric linking API and thus open handler
count was never decreased. This patch fixes that.
We need to add separate open hander count for amthif which
is handled out of link/unlink functions and doesn't break
the symmetric API.

Last we do not waste clients slots if amthif or wd are not present
in the device. we don't need to allocates slots ahead
it is all covered by link/unlink before the devices is responding
to user space connection and thus not racing on allocation

mei: cancel stall timers in mei_reset

2013-09-26T20:56:53+00:00

Unset init_clients_timer and amthif_stall_timers
in mei_reset in order to cancel timer ticking and hence
avoid recursive reset calls.

mei: don't get stuck in select during reset

2013-07-27T00:54:30+00:00

Clear pending connection after hw reset but before hw start
and wake up the waiting task in poll. Signal POLLERR in select
when device went through reset.

Add wrapper mei_cl_is_connected for checking if
the device and client are connected.

mei: wake also writers on reset

2013-07-25T05:49:57+00:00

wake writers otherwise might have processes waiting
endlessly on wait_tx during reset

mei: don't have to clean the state on power up

2013-07-24T02:31:35+00:00

When powering up, we don't have to clean up the device state
nothing is connected.

mei: check whether hw start has succeeded

2013-06-24T23:33:28+00:00

hw start may fail therefore the reset flow has
to check for the return value
