loading on a particular version of Windows. For example, a .INF file
for a Windows 2000 driver may have an empty [foo.NT.5.1] section which
will be ingored on Win2K (whose .INF parser won't look for sections
decorated with .NT.5.1) in favor of a [foo] section. Likewise, a
WinXP file will have an empty [foo] section which will be ignored in
favor of [foo.NT.5.1].
The problem is, we can handle both Win2K and WinXP drivers, and we
don't want to exclude either one.
As a workaround, we try to pretend we are WinXP by default and search
for sections decorated with .NT.5.1, but if we don't turn up any records,
we assume that maybe we're being fooled by a sabotaged .INF file and
make one more pass looking for undecorated sections instead.
This allows us to parse the .INF files for both the Win2K and the WinXP
Centrino wireless drivers.
I'd give anything for 5 minutes alone in a room with whoever wrote
Microsoft's .INF file parser. Just 5 minutes. That's all.
their lines.
Properly discard PCMCIA device declarations. I plan to support
PCMCIA cards, but they don't work yet, and it appears some .INF files
declare both PCI and PCMCIA device instances.
keys, don't just do a substring match on "Ndi\Params". Instead, check
explicitly for strings that begin with "Ndi\Params". Why? Because it's
possible to create your own keys with different paths, like
"PROSetNdi\NdiExt\Params" which is what Intel does in their PRO/1000
driver's .INF file.

subr_ndis.c: correct the behavior of ndis_query_resources(): if the
caller doesn't provide enough space to return the resources, tell it
how much it needs to provide and return an error.
subr_hal.c & subr_ntoskrnl.c: implement/stub a bunch of new routines;
ntoskrnl:
KefAcquireSpinLockAtDpcLevel
KefReleaseSpinLockFromDpcLevel
MmMapLockedPages
InterlockedDecrement
InterlockedIncrement
IoFreeMdl
KeInitializeSpinLock
HAL:
KfReleaseSpinLock
KeGetCurrentIrql
KfAcquireSpinLock
Lastly, correct spelling of "_aullshr" in the ntoskrnl functable.

Add a -n flag to ndiscvt to allow the user to override the default
device name of NDIS devices. Instead of "ndis0, ndis1, etc..."
you can have "foo0, foo1, etc..." This allows you to have more than
one kind of NDIS device in the kernel at the same time.
Convert from printf() to device_printf() in if_ndis.c, kern_ndis.c
and subr_ndis.c.
Create UMA zones for ndis_packet and ndis_buffer structs allocated
on transmit. The zones are created and destroyed in the modevent
handler in kern_ndis.c.

than a char array. Emitting the data as a big char array works fine in
the typical case, where a .sys file may be ~50K in size. Unfortunately,
some .sys files can be several hundred Kbytes in size, or even several
megabytes in size. One extreme case is the Intel centrino wireless
driver, which is 2.4MB. This causes us to emit an ndis_driver_data.h
file that's on the order of 15MB in size, and gcc consumes enormous
amounts of virtual memory while trying to compile it. On my laptop,
with 128MB of RAM and 256MB of swap space, gcc consumed all available
VM and crashed without being able to compile if_ndis.o.
By emitting the array as assembler, we bypass the C compiler and consume
much less memory. I was able to easily test compile if_ndis.ko with the
centrino driver on my laptop after this change.
This is merely a convenience, and should not have any operational effect
on the NDISulator itself.
definitions for more than one device (usually differentiated by
the PCI subvendor/subdevice ID). Each device also has its own tree
of registry keys. In some cases, each device has the same keys, but
sometimes each device has a unique tree but with overlap. Originally,
I just had ndiscvt(8) dump out all the keys it could find, and we
would try to apply them to every device we could find. Now, each key
has an index number that matches it to a device in the device ID list.
This lets us create just the keys that apply to a particular device.
I also added an extra field to the device list to hold the subvendor
and subdevice ID.
Some devices are generic, i.e. there is no subsystem definition. If
we have a device that doesn't match a specific subsystem value and
we have a generic entry, we use the generic entry.
the case where there's an entry in the manufacturer's device list but
no corresponding installation section (and hence no AddReg assignments),
i.e. if dev = find_assign(sname, "AddReg"); returns NULL, then
don't try to dereference dev.
There is a fundamental problem with the handling of .INF files that
contain definitions for multiple devices: right now we dump all the
AddReg sections that we find, but don't distinguish what device they
belong to. This often results in duplicate keys.
