The Kernel-Processor-Power Event Provider

Starting with Windows Vista SP1, drivers for Processor Power Managment (PPM) register an event provider and write events to it. Starting with Windows 7, the kernel joins in:

Provider GUID:	{0F67E49F-FE51-4E9F-B490-6F2948CC6027}
Provider Name:	Microsoft-Windows-Kernel-Processor-Power
Symbolic Name:	PPM_ETW_PROVIDER

The PPM drivers and the kernel, of course, know of the provider only by the Provider GUID. The Provider Name is what's stored in the registry for this GUID. It's then the Name that the Event Viewer shows for the Provider in the Details tab for an event that actually has occurred and been logged. It's also the name to use when referring to this provider in such tools as WEVTUTIL and the Performance Monitor. The Symbolic Name is what public symbol files for the kernel show as the programming label for the GUID as an internal kernel variable.

An instrumentation manifest for the Microsoft-Windows-Kernel-Power provider is compiled into Microsoft-Windows-Kernel-Processor-Power-Events.dll (but ADVAPI32.DLL in version 6.0) as a resource named WEVT_TEMPLATE. This event template is the source of the plain-language names that the command wevtutil gp Microsoft-Windows-Kernel-Processor-Power extracts for channels, opcodes, levels, tasks and keywords. Its location is known already in the registry when Windows is installed.

As for any event provider, the compiled instrumentation manifest can be de-compiled to something like the XML it was written in, albeit without recovering symbolic names that compilation did not transfer to the manifest. Microsoft’s WEVTUTIL has options that can make a good start at this, and hackers have surely written tools that do better or differently. If that were the end of presenting the possible events, then this page would not exist.

The aim here is instead to capture something of the events’ development through successive versions, both in the compiled manifests and in the kernel’s code for writing the events. Notably, the manifests are sometimes wrong (not that this will surprise any programmer who has ever tried preparing one and keeping it synchronised with the code). With sufficient resources and attention, the presentation below may someday develop into describing what causes each of the possible events and what their parameters of event data mean. Remember, though, that such documentation really is Microsoft’s to write.

Channels

Two channels are defined for the provider. Each takes a different selection of the many possible events.

Channel ID	Channel Name	Versions
8	System	6.0 SP1 and higher
16	Microsoft-Windows-Kernel-Processor-Power/Diagnostic	6.0 SP1 and higher

The System log is familiar to all system administrators and many users. The Event Viewer shows it prominently among the Windows Logs. The others appear in the Event Viewer as "Applications and Services Logs". The diagnostic channel is not ordinarily enabled and is not even presented as a log that might be enabled except if the "Show Analytic and Debug Logs" option is checked.

When the Kernel-Processor-Power provider was new, and was written to only from PPM drivers, all the defined events went to the System channel except for the one that was directed instead to the diagnostic channel. That this is at all remarkable is because in Windows 7 and higher the vast majority of possible events from this provider go to neither of the defined channels and can never be seen except by creating a custom log.

Events

Also in the registry is that plain-language descriptions of events, such as show in the Event Viewer, are resolved from the same DLL's message-table resource (which is in practice in the language-specific MUI file). The vast majority of the possible Kernel-Processor-Power events do not have a friendly description.

The tables that presently follow are of all Kernel-Processor-Power events that are listed in any compiled instrumentation manifest for kernel versions up to and including the original release of Windows 10. If you want a tabulation that is more up-to-date, try getting it from Microsoft and wonder why you’re here at all.

Names given for channels, levels, opcodes, tasks and keywords are from the compiled event template. That opcodes and tasks are not defined in version 6.0 is not stated explicitly for each event. For brevity, the (event) version, opcode and task are omitted unless they are non-zero, but beware that zero is not meaningless: the name "win:Info" is formally defined for opcode zero. The high byte of the keyword is not rendered as text since it reliably corresponds to the channel. Where rows, are broken out according to the event version or kernel version, the separate rows are sometimes, even often, not alternatives but are instead to be understood as additive. This applies especially to the Event Data: new event versions ordinarily extend the parameters, rather than replace any.

Main Series

All the events that are yet defined are numbered sequentially from 1. Inevitably, they extend ever further in successive Windows versions:

• 8 in 6.0;
• 48 in 6.1;
• 76 in 6.2;
• 88 in 6.3;
• 112 in 10.0.

Though some have fallen out of use in the sense that they never are written in later versions, their IDs are not reused and information about them is retained in the compiled event template, presumably so that tools running on a new Windows can interpret logs collected from computers that run an old Windows.
