Hi:
We have the following problem:
I want to be able to allocate pools of memory [64 MB blocks].
I do that using passing blocks of memory to IoAllocateMdl…
so far so good…
After the Mdl has been allocated I lock the pages using MmProbeAndLock
[Access = KernelMode]
This goes fine, till I have locked about 190 MB of memory…
After which the system panics… with a insufficient number of PTEs
message.
We were told that WinNT 4.0 has a 50K PTE limit.
We wanted to know if XP has this kind of a limit too.
The memory has to be locked down [non-paged]. Avail @ dispatch_level.
We are having 512 MB of physical can be extended to 1 G if required.
Please let me know… how to get around the problem.
TIA
