Hi All,
While skimming thru the WinOF code I came across few doubts.
First of all ,following is my understanding:-
1) ibbus.sys provides two interfaces ,one on upper edge (GUID_IB_AL_INTERFACE)
for IB Clients and another on lower edge (GUID_IB_CL_INTERFACE) for HCA drivers
to register themselves for a particular HCA device.
If anything is wrong please correct me.
My doubts are regarding the loading of drivers...
PCI bus driver enumerates the attached devices and comes to know about an
attached device and with the help of PnP manager it comes to know about the
Device's Instance ID (DIID) and is accordingly able to load the mthca drivers
(mthca.sys).
When are ibbus.sys and ibiou.sys comes into the picture.
To be specific when are their entry point routines and their adddevice routine
are called.
Also if somebody has some kind of documentation on Windows OFED stack ,I would
be highly grateful to himi/her sharing on the group.
If I missed out something or misunderstood something ,a correction would be
highly appreciated.
Regards
