kmdf resource type of 0x81 from WdfCmResourceListGetDescriptor

NTDEV
1

This type does not seem to be defined. Any ideas?

Thanks,
Greg

You should ignore any undefined type. In this case, looking in WDM.h
yields the info you want

#define CmResourceTypeNull 0 // ResType_All or
ResType_None (0x0000)
#define CmResourceTypePort 1 // ResType_IO (0x0002)
#define CmResourceTypeInterrupt 2 // ResType_IRQ (0x0004)
#define CmResourceTypeMemory 3 // ResType_Mem (0x0001)
#define CmResourceTypeDma 4 // ResType_DMA (0x0003)
#define CmResourceTypeDeviceSpecific 5 // ResType_ClassSpecific
(0xFFFF)
#define CmResourceTypeBusNumber 6 // ResType_BusNumber
(0x0006)
#define CmResourceTypeMemoryLarge 7 // ResType_LargeMem
(0x0007)
#define CmResourceTypeNonArbitrated 128 // Not arbitrated if 0x80
bit set
#define CmResourceTypeConfigData 128 // ResType_Reserved
(0x8000)
#define CmResourceTypeDevicePrivate 129 // ResType_DevicePrivate
(0x8001)
#define CmResourceTypePcCardConfig 130 // ResType_PcCardConfig
(0x8002)
#define CmResourceTypeMfCardConfig 131 // ResType_MfCardConfig
(0x8003)

0x81 = CmResourceTypePort | CmResourceTypeNonArbitrated

You should ignore this particular resource descriptor and move on to the
next one

Did you notice that your definition of 0x81 collides with
CmResourceTypeDevicePrivate, which is also 0x81?

My bad, it is private and not the bit field combination I pointed out earlier (I was thrown off by the value mentioned in the comment for 129, 0x8001, that is obviously wrong :wink: )
