WDF Logo Requirements Regarding Coinstallers - driver writing != bus driving - Site Home

I've been asked many times, if a driver developer can avoid using WDF coinstallers. The answer is "yes, if the system already has the needed version of WDF installed (e.g. you want to install a WDF 1.5 driver in Vista RTM)". So, the next question that usually comes up is "Will I be able to have my WDF driver, which has no coinstaller, WHQL-signed". So, in this post I'll explain our WDF Logo requirements that are related to the coinstallers.

PART 1: WDF Logo Requirement

The official name of the requirement is “DEVFUND-0039: Windows Driver Framework (WDF) drivers are packaged to contain the RTM fre versions of redistributables”, but the title is very misleading!

The current situation (in WLK 1.4) for WHQL-signing is:

Win7 + WDF 1.9: No coinstaller restrictions. This means that you can use any WDF 1.9 coinstaller (beta, RC, RTM, intermediate builds, etc) or you can use no coinstaller. Since the coinstaller is not used to update a Win7 system, we wanted to allow driver submissions before Win7 RTMed, so this is a temporary policy. Now that the WDF 1.9 RTM coinstallers are out, it is suggested that you use those. We might update WLK 1.4 with a QFE to make the usage of the RTM coinstallers mandatory.
Win7 + WDF 1.0-1.7: You can use either an RTM coinstaller or no coinstaller
Windows 2000-Vista + WDF 1.9: You need to use the RTM WDF 1.9 coinstaller or no coinstaller. If you use the coinstaller, then you need to install the latest errata filters from http://winqual.microsoft.com, (under the name “WLK Update Filters”) and apply them on the DTM controller.
Windows 2000-Vista + WDF 1.0-1.7: You can use any RTM WDF coinstaller or no coinstaller (of course, you need to make sure that the needed version of WDF is already inbox if you don't submit a coinstaller).

After WLK 1.5 comes out (October 2009) the WHQL-signing situation will be:

For all operating systems and all versions of WDF (1.0 - 1.9) you can use either an RTM coinstaller or no coinstaller (if you don't submit a coinstaller, then the same restrictions as above will apply).

NOTES:

If you don't submit a coinstaller, then you'll get a warning (not an error) saying that you it's possible that in downlevel operating systems your driver might not be working (e.g. a WDF 1.7 driver will work in Vista SP1 without a coinstaller but not in Vista RTM).
As noted above, if you have an older version of the WDK, you can still compile a WDF 1.5 driver, submit it for WHQL-signing bundled with the WDF 1.5 RTM coinstaller (or no coinstaller in Vista+). Of course, this means that you'll be using older tools (compiler, prefast, etc) to build/validate your driver.

PART 2: Sample INFs

Now let's go to the inf files. What changes need to be made, if you are sure that you don't need a coinstaller?

1) KMDF: Remove all references to wdfcoinstaller0100X.dll from the inx. I'm using the echo sample from the Win7 RTM WDK as an example:

I've removed the sections ECHO_Device.NT.CoInstallers, ECHO_Device_CoInstaller_AddReg, ECHO_Device_CoInstaller_CopyFiles, SourceDiskFiles (the one at the bottom) and ECHO_Device.NT.Wdf.

2) UMDF: You need to replace WUDFUpdate_0100X.dll with the inbox coinstaller wudfcoinstaller.dll, which is always installed as part of UMDF (i.e. you don't need to have it as part of your driver package). I'm using the UMDF echo sample from the Win7 RTM WDK.

3) KMDF 1.9 + UMDF 1.9 + WinUSB 1.9: In the Win7 RTM WDK we do have the sample WudfBioUsbSample.inf that uses all 3 frameworks. This would normally use 3 coinstallers, however, since the sample is Win7-only and these components are all inbox, we don't need to use coinstallers. I've pasted the inf file directly from the WDK with minor stylistic modifications.
