OID_802_3_CURRENTADDRESS Vs OID_802_3_PERMANENTADDRESS
Hi All,
When NDIS calls OID_802_3_PERMANENTADDRESS ? And if it gets a valid
MAC address what makes it to call a OID_802_3_CURRENTADDRESS ??
Does it mean a NIC driver can change its MAC address on the FLY...
If so how can NDIS be informed about the same....
One more query, if i change the Routing table entries dynamically
will this reflect in NDIS calling the Miniport adapter with
OID_802_3_Currentaddress???
Can a change in the Routing table trigger a call to OIDs related to
MAC address??
Thanks in advance

register interrupts
Hi all,
Thank you very much in advance.
my PCI device have 7 subsystems. each one have read write and IOCTRL
functionality. 3 of them use interrupts.
therefore I have to write 7 separate drivers for each subsystems.
I do not want to install this drivers. they may be work simultaneously.
I have problem to register interrupts. How should get information to
register interrupts(interrupt vector and level).

Miniport that should not be unloaded at stand by and hibernation
I have a virtual miniport adapter (NDIS 6.0) that I need to remain loaded
during stand by and hibernation (I am communicating with a service which I
don't control that demands this). I have set
NDIS_MINIPORT_ATTRIBUTES_NO_HALT_ON_SUSPEND in the registration attributes
in MiniportInitializeEx.
Still when the PC is going into stand by MiniportHalt is called with
haltAction = NdisHaltDevicePoweredDown.
Anyone who has an idea of preventing this?

Preinstalling Driver with DIFxApp
I want to install a signed USB driver with WIX 2 and DIFxApp.
This works as long as the USB device is connected to the PC during
installation. If no device is connected DIFxApp does not report an error and
adds an entry to Add/Remove Programs. But when I connect the device Windows
can't find the driver and asks for the *inf file.
The log reports the following:
DIFXAPP: INFO: No matching devices found in INF "foo.inf" on the Machine.
DIFXAPP: INFO: No drivers installed. No devices found that match driver(s)
contained in 'foo.inf'.
DIFXAPP: SUCCESS:Installation completed with code 0xE000020B.
So what can I do to preinstall a driver with DIFxApp?

KeStackAttachProcess
Hello.
I have written a driver routine that changes its thread context to make a
quick read of RAM from another process.
As the topic here suggests, it uses KeStackAttachProcess(), performs the
quick read, and leaves with KeUnstackDetachProcess().
It is generally stableâ??I am not trying to read kernel RAM or anything
dangerous so I donâ??t get any blue screens, but if the target process closes
while my thread is over there my application deadlocks so hard it can not be
closed by any means but a reboot.
Is there any sure way to prevent this?
I tried using CLI and STI but then I get blue screens whining about
privilege levels. I use KeLowerIrql( DISPATCH_LEVEL ) but I get the same
error anyway (I thought DISPATCH_LEVEL could always use CLI?).
I think I could reduce the chances of this deadlock (currently at 94%â??if the
target closes, my application WILL deadlock) using
PsGetProcessExitProcessCalled() and then aborting if TRUE, but then I think
this is only reduces the chances, not eliminates them. What if the process
is closed after I call that function but before I go into it with
KeStackAttachProcess()?
Is there any way to get a brief lock that absolutely ensures the process
cannot close while I am there?
Thank you.
P. S.: I call ObReferenceObjectByHandle() before going into the target
process. This is supposed to raise the reference count on the process so it
canâ??t fully close, which should have been preventing my problem.
Am I being mislead? Tag: Graqphics driver DDraw/DXVA 1.0 related query Tag: 99820
Filter driver on 64 bit OSes
Hi there,
I just have finished up my filter driver writting on 32bit WinXP and Vista.
The next thing I am currently doing is porting this filter driver to 64 bit
OSes. I have this filter driver built with "Win XP 64 bit build Envirnoment"
and it ended up these drivers neither work on XP nor Vista.
From the registry, I can tell that the filter driver service has been loaded
up but I can't see any my debug message print out from my driver.
I have been searching on net and forums but nothing useful except this thing
called "Kernel-Mode Code Signing". I start to suspect that my filter driver
does not work mostly because of this so-called "code-signing policy". Does
anyone can tell me am I on the right track?
Many thanks in advance.

Help supporting WIA for a video driver

How to identify whether a function pointer is valid?
My USB driver sends Irp to query USB_BUS_INTERFACE_USBDI_V1
from bus driver. It returns STATUS_SUCCESS and fills the structure.
I use USB_BUS_INTERFACE_USBDI_V1.IsDeviceHighSpeed() to query
the device running speed mode.
However, the IsDeviceHighSpeed() function pointer is invalid and not NULL.
The system crashes immediately after the driver call the function pointer.
The USB EHCI driver is 3rd party driver. I'm not surprised.
I want to know how the kernel driver to identify whether the function
pointer
is valid before it calls the function pointer.
Or how the kernel driver handle this kind of case.

After configuring the netzworkdevice (IP-Adress, etc.) everything works fine.
But:
Can i configure the Networkdevice automatically after Installation? That
means that after the correct driver is installed, the networkdevice should
have an IP-Adress.
Can i configure the IP of the connected Device remotely? (For testing

SAA7134 & Texas XIO PCI-e-2-PCI bridge
Hello All,
I have a board with PCI-e-2-PCI Bridge XIO2000 from Texas and four
SAA7134 Philips codecs behind it. Windows XP SP2 sees all four devices
as being connected to some PCI bus. I have developed a driver for
SAA7134 Philips codec and loaded it for all four devices behind this
PCI-e bridge. I tested the driver with Philips devices on conventional
PCI bus - it worked in the way I expected it. Everything changed with
this new board. I have tons of mysterious errors. Trying to access one
device memory mapped registers I affect register settings of another
device on the same bus. I miss critical interrupts with almost
enormous lag. Almost everything broke. My driver is conventional WDM.
It uses memory mapped registers and interrupts line. SAA7134 performs
bus master scatter-gather DMA video data transfer.
So, here is the question - are there any special things about
developing drivers for devices, connected to PCI-e bus?
With best regards,

Accessing disabled SCSI devices via Storport
I am developing the SCSI device test application. It is intended mainly for
SCSI device firmware developers and testers, and allows user to execute
manually any SCSI command for the selected SCSI device. During the
development and testing of the firmware the device might not be able to
answer properly to SCSI commands. In this case it is necessary to disable the
device object in the Device Manger window. Disabling the device object
prevents the class driver from sending the SCSI commands for normal
functioning. The special pseudo class driver was developed for the
transparent device access. This driver sends IRP_MJ_SCSI IRPs with the SRBs
directly to storage adapter objects (Scsi0:, Scsi1:, etc). This worked fine
with SCSI Port but does not work with Storport. As I have learned from this
newsgroup the Storport does not allow sending SRBs directly to adapter
object. Sending SRBs to SCSI device object works fine but when the device is
disabled there is no device object at all. The SCSI PASS THROUGH interface
also does not work through the Storport for the disabled SCSI device.
Is there a way to send the SCSI command to the disabled SCSI device via the
Storport?
Thanks a lot for advice. Tag: Graqphics driver DDraw/DXVA 1.0 related query Tag: 99759

delreg section in INF not truly deleting registry entry
I have a heisenbug I could use help on.
I have service that creates several registry keys. The service has an
associated INF file which has a DefaultUninstall section which is called by
our product's installer when removing the service. The DefaultUninstall
section calls out a delreg section which deletes about 20 keys from the
registry. All but one of these keys gets deleted correctly.
Now for the heisenberg portion of the bug. The installer prompts the user
for a reboot at then end of the removal process. If I pull up regedit
before saying yes to the reboot, the key in question is indeed not in the
registry any longer and is not when the system comes back from reboot. If I
do not pull up regedit and just reboot, the key is still present when the
system comes back from reboot. Obviously, regedit is causing the change to
be permanent in some way.
Is there some lazy write problem here? Is there a way from the INF I can
flush or commit the reg changes?
Thanks.

Verifier doesn't catch IRQL violation
I accidentally called ZwReadFile at APC_LEVEL IRQL (holding a fast mutex
actually) in a driver running on Vista RTM and got a weird result.
ZwReadFile just wouldn't return. No crash, no bad status return, the thread
just hung. Then of course the application was stuck with an open handle and
neither the app or the driver could die properly.
I turned on DriverVerifier for my driver with all options selected except
low resource simulation and it never complained.
It seems 1) ZwReadFile should be checking the current IRQL and returning a
bad status if it isn't PASSIVE_LEVEL and 2) DriverVerifier should have
caught this no?
Just FYI to any MSFT folks that might care.
I caught it pretty fast on my own, but this could cause someone no end of
pain if they didn't know what to look for.
Btw, this driver ran fine on XP SP2...don't know if that was (bad) luck or
just a change in under arching operation.
Haven't tried SDV on it yet.

IRP_MN_READ_CONFIG request or the GetBusData method of
BUS_INTERFACE_STANDARD"
Please tell me that I am wrong! I really would rather not calculate
the offset from 0xe0000000 (using bus, dev, func) and manually read
physical memory at that location to get to the extended config space.
I WANT to use OS calls!
Thanks.

Ethernet driver buffer allocation
This may not be the proper spot to post, but I figured it was a good starting
point. I also suspect this may be dependent upon the actual Ethernet device
driver, and not an industry standard. That being said:
When data is transferred across an Ethernet connection using, say a TCP-IP
socket connection, the end caller issues a receive call, and passes in a
pointer to a buffer where the data is written.
My question is:
a) Is the data being transferred ONLY written into that buffer which is
passed in, or
b) is there an intermediate buffer contained w/in the driver to store the
data as it is transferred across the medium (and then copied into the buffer
passed in on the receive call)?
I am trying to minimize copies in my code, because I have large amounts of
data being transferred. Again, I realize that this may be totally dependent
upon the ethernet card being used, I just was curious if there was an
industry standard, or some underlying protocol/handshaking to which I was not
aware of.
Thanks. Tag: Graqphics driver DDraw/DXVA 1.0 related query Tag: 99669
Getting started modifying a NT serial card driver to run on XP
Hello
I have the source code to a driver that works fine on NT4 but we now
need to get it to work on XP. Our testing indicates that the driver
does not work on XP. It is possible that it is a configuration issue
however - as the driver gets some data from the registry - I am
checking if we have that correctly configured. But I am guessing that
is not the problem.
Should a driver written for NT4 work on XP without change? The driver
is for an RS422 multidrop card. Are there any areas of the driver
code which I should be watching out for? Is this a total re-write
situation or only minor changes?
Any comments would be much appreciated.

Can't get reading extended config space to work on Vista
I am pretty sure that the BIOS is allowing Vista to take control of
PCIe since in WinDBG I can do a !pci 0x101 3 0 0 (my device is on bus
3, dev 0, func 0):
..[Config Space 0x00-0xFF omitted]...
Enhanced Capabilities:
100: CapID 0002 Virtual Channel Capability
Version 1
NextPtr 800
800: CapID 0001 Advanced Error Reporting Capability
Version 1
NextPtr 000
However on another machine running Vista where I'm pretty sure the
BIOS does not do the _OSC method and I think it is verified when I
run !pci 0x101 on the same device there will be no "Enhanced
Capabilities listing at all.
Neither of the two Microsoft sanctioned ways (that I am aware of (i.e.
GetBusData and IRP_MN_READ_CONFIG)) to access extended config space
worked for me. I have even used the example verbatim from
http://msdn2.microsoft.com/en-us/library/ms795302.aspx. The status
returned from the IRP_MN_READ_CONFIG method is
STATUS_INVALID_DEVICE_REQUEST.
I've even tried installing Vista SP1 Beta, but the results are the
same.
Any other venues I should take/investigate?
Thank you in advance.

missing DirectoryChange notifications
Hi all,
I'm writing an IFS minifilter doing some HSM stuff. Most operations are
queue using FltQueueXXX functions. In worker function changes to files are
done using e.g. FltSetInformation, FltWriteFile. This works very well.
But user mode applications using NtNotifyChangeDirectoryFile or
ReadDirectoryChangesW (e.g. Explorer) are not notified about these changes.
Changes on files triggered from any user mode application are notified!
How can I notify changes from IFS filter (system thread)? Tag: Graqphics driver DDraw/DXVA 1.0 related query Tag: 99661
Multple LUN support question for USB flash drive
Hi,
I'm trying to expose a USB composite device with the mass storage interface
at interface 2. Although I reported support for Hierachial support (HiSUP
bit set to 1), the system does not try to query me for my other LUNs except
for LUN 0. I never received the REPORT LUNS command that is suppose to be
compulsory when HiSUP bit is set.
When I change the mass storage interface to interface 0, I get the INQUIRY
command for LUN 1 as well and all is well.
Question is, why doesn't the system check for additional LUNS when my mass
storage interface is not 0? Is this a requirement?
Thanks.

FTDI's FT232R chipset Junk data bytes
Hi All,
I am writing a Custom WDM USB-UART driver(Single VIRTUAL COM PORT)
for FTDI's FT232R chipset.
In my InitializationModule() and startdeviceroutine() I could able to
Get the device descriptor
and configure the Device perfectly. I am getting the Interface and
pipe information correctly.
My problem is after start device, If I try to Read data from the
device by calling the following
//Satrt the request
ulFlags = USBD_TRANSFER_DIRECTION_IN | USBD_SHORT_TRANSFER_OK;
UsbBuildInterruptOrBulkTransferRequest(pCtx->m_pUrb,
sizeof(struct _URB_BULK_OR_INTERRUPT_TRANSFER),
hPipe,
pbBuffer, NULL, cbBuffer, ulFlags, NULL);
// Setup completion proc
IoSetCompletionRoutine(pCtx->m_pIrp,(PIO_COMPLETION_ROUTINE)
RequestCompletedThunk,pCtx,TRUE,TRUE,TRUE);
// Call next device with this IRP
status = IoCallDriver(pCtx->DeviceExtension-
>TopOfStackDeviceObject, pCtx->m_pIrp);
in My Completion routine I am getting 2 bytes of junk data, Which is
unexpected(There is no data kept in port).
When I open the Virtual Com Port and write some data bytes, still I am
getting these 2 junk bytes.
I tried to resolve this issue by resetting the pipe. Still problem
exists.
Can anybody help me to get rid of that unnecessary junk bytes.
Your valuable suggestions are always appriciated.
Thanks in advance.

NDIS Allocate memory fail???
Hi,
I am writing a NDIM IM driver. In order to communicate with user land
application, I allocate 3 buffers on nonpaged memory 10 MB each.
My driver gets success to allocate memory in first time only for all buffers.
Next time on wards, driver gets fail to allocate memory. I am very much
sure that there is no any memory leak which I have tested.
Please suggest me what should I do??

Driver Test Manager (2 tests fail in the unclassified tests)
Hi,
We are using the DTM (Driver Test Manager 1.0.6417.304) to test our
kernel mode device driver (mirror driver) to get a digital signature.
We are using the following configuration:
Controller: Windows 2003 Server
Studio: Windows 2003 Server
Client: Windows Vista Home Basic
We set up the unclassified tests and run them (we don't need a logo,
we only need a signature).
We received 2 errors in the following tests:
- Run INFTest against a single INF (Error message in RunJob: Could not
find user specified INF files)
- Plug and Play Driver Test (3 Error messages in RunJob: DeviceId is
NULL)
Do you have any idea ? Tag: Graqphics driver DDraw/DXVA 1.0 related query Tag: 99654

Windows XP & non-paged pool
Dear All,
At my driver I need a really huge memory buffer. I am trying to
allocate it from non-paged memory pool, since I need to perform a
series of DMA transfers from lots of PCI devices installed in the
system. Actually, every instance of my driver requires about 24 Megs
of memory and we are planning to have about 16 such devices installed.
What a disaster, I can load drivers only for 6 my devices, all other
fail on allocating memory from non-paged pool. I decided to allocate
memory from paged pool and lock it down in physical memory, using
MmProbeAndLockPages(), but was able to load only 4 instances of my
driver. What I am doing wrong?
With best regards,

IJolietDiscMaster->AddData returning STG_E_INVALIDFUNCTION
Hi there,
I am attempting to add a previously created IStorage container to an
IJolietDiscMaster interface, although the file appears to have been created
correctly and no errors were returned during it's creation, nor the streams
that were added to it, unfortunately it returns STG_E_INVALIDFUNCTION.
Could this be due to the way that I have created the streams? or not
closed them correctly after adding data?
Many thanks in advance as any help on this would be fantastic.
