driver path exerciser test in hct-help!!!!!!!

[zyx]

Hi,

In driver path exerciser test I get a wdm error 20f.In documentation
the following is given.

A Power IRP has an invalid status. (Any Power IRP must have its status
initialized to STATUS_NOT_SUPPORTED.) (IRP specified.)

But previously I enabled driver verifier and tested my driver.when I
tested it didnt give me any I/O verification errror.I enabled both i/o
verification and enhanced i/o verification option.even though I didnt
get this error.But now its showing in hardware compatinility test.
Thanks in advance

Device path exerciser has hooks to work directly with driver verifier. The
tool is available through the DDK/WDK, you should run it standalone and
debug your driver.

Hi,
I am not getting you.sorry I am new to this.what do you mean by
standalone.previously I ran the driver with verifier.exe that comes
along with OS.In that as I said before I enabled both the I/O
verification and enhanced I/O verfication.But I didnt get this error.
I am not sure whether I am testing my driver in a right way.steps I
did
1.Installed hct with default options.
2.I installed my driver,ie I have connected the hardware to the
system.
3.I just selected only driver path exerciser ans started the test.
observations:
Initially I got a blue screen .Dump shows that it crashes in
omci.sys.I am not sure what this means.Automatically my system
rebooted and I got the wdm error 20f in my driver.
Thanks in advance.

Driver Verifier is for the most part a kernel support routine cheker, so if
your driver does not run a certain path it does not check that path.
Device Path exerciser has specific hooks into the verifier through
undocumented interfaces, this is mentioned in the documentation for device
path exerciser that comes with the DDK. So you have a bug in your driver,
and you need to track it down.

Now, you may find that running the device path exerciser standalone (rather
than in the HCT's) will make it easier to reproduce and track down the bug.
Under any circumstances, I recomend the documentation for device path
exerciser that is in the directory with the tool provided with the DDK.

Hi,
Thanks for the info.I am getting a wdm I/O verification error of my
driver.20f.

wdm error dont create a dump.Is there a way to set in any system
properties so that we get dump.bug checks create dump.But this i/o
verfication wdm errors doesnt create dump!!!!!!! or does it create in
some other place.

it.could you please tell ne if there are other test to test my
driver.I am sure which to run
Thanks in advance

Not exactly!
You might want to read the following before you make any rash decisions!
