|
WOW Thunking design:
|
|
|
|
Thunks are generated as follows :
|
|
|
|
16-bit :
|
|
acmBootDrivers->acmInitThunks :
|
|
|
|
Generate calls to 32-bit drivers if we're in WOW call across
|
|
to KERNEL to find thunking entry points.
|
|
|
|
If we're thunking 'load' all the 32-bit ACM drivers as well as
|
|
the 16-bit ones.
|
|
|
|
Priority is always to find a 32-bit driver first but this is
|
|
done via searching for one on open.
|
|
|
|
The internal flag ACM_DRIVERADDF_32BIT is specified when
|
|
calling IDriverAdd and this flag is stored in the ACMDRIVERID
|
|
structure.
|
|
|
|
IDriverAdd->IDriverLoad->IDriverLoad32
|
|
|
|
The 16-bit side calls the 32-bit side passing in the driver
|
|
alias which is used to compare against the aliases on the 32
|
|
bit side and the 32-bit HACMDRIVERID is passed back for the
|
|
relevant driver and stored in the hdrvr field of the
|
|
ACMDRIVERID structure.
|
|
|
|
IDriverOpen->IDriverOpen32
|
|
|
|
The parameters are passed to the 32-bit side using the hdrvr
|
|
field deduced from the HACMDRIVERID as the 32-bit HACMDRIVERID.
|
|
|
|
IDriverMessageId->IDriverMessageId32 :
|
|
|
|
If the driver is 32-bit (as identified in the ACMDRIVERID
|
|
structure) then call IDriverMessageId32. The hadid for
|
|
the 32-bit driver is stored in the hdrvr field of ACMDRIVERID
|
|
on the 16-bit side.
|
|
|
|
IDriverMessage->IDriverMessage32
|
|
|
|
If the driver is 32-bit (as identified in the ACMDRIVERID
|
|
structure pointed to by the ACMDRIVER structure) then call
|
|
IDriverMessage32. The had for the 32-bit driver is stored
|
|
in the hdrvr field of ACMDRIVER on the 16-bit side.
|
|
|
|
Stream headers
|
|
|
|
These must be persistent on the 32-bit side too and kept
|
|
in synch.
|
|
|
|
They are allocated on the 32-bit side for ACMDM_STREAM_PREPARE
|
|
and freed on ACMDM_STREAM_UNPREPARE. While in existence
|
|
the 32-bit stream header is stored in the dwDriver field in
|
|
