New Revision: 55537
URL: http://svn.reactos.org/svn/reactos?rev=55537&view=rev
Log:
[NTOSKRNL]
- Implement IopFixupResourceListWithRequirements to replace
IopCreateResourceListFromRequirements
- This functions fills in gaps between required resources and currently allocated
resources in the resource list
- It also implements support for alternate requirement descriptors which
IopCreateResourceListFromRequirements ignored
- Fix a critical bug in requirement processing that could result in the kernel allocating
resources outside the devices requested range
- Now the PnP manager will actually claim resources that the device reports that it needs
but it does not currently have
