d329ad6035 Add preliminary support for PCMCIA devices in addition to PCI/cardbus.
if_ndis.c has been split into if_ndis_pci.c and if_ndis_pccard.c.
The ndiscvt(8) utility should be able to parse device info for PCMCIA
devices now. The ndis_alloc_amem() has moved from kern_ndis.c to
if_ndis_pccard.c so that kern_ndis.c no longer depends on pccard.

NOTE: this stuff is not guaranteed to work 100% correctly yet. So
far I have been able to load/init my PCMCIA Cisco Aironet 340 card,
but it crashes in the interrupt handler. The existing support for
PCI/cardbus devices should still work as before.

307ca1d625 Some Windows .INF files are deliberately sabotaged to prevent them from
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.

e7e7d5e91e Deal with keys with descriptions that have empty fields in some of
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.

93335315ad Yet another inf file handling tweak: when checking for Ndi\Params\foo
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.

0a9e1a08a1 Tweak ndiscvt to support yet another flavor of .INF files (look for
the NTx86 section decoration).

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.

ade996adb6 Handle WinNT .inf files with a $windows nt$ signature but no .NT decorated
AddReg sections.

Also insert extra newline after emitting device name overrides.

f07cc658a4 Clean up ndiscvt a bit (leaving out the -i flag didn't work) and add
copyrights to the inf parser files.

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.

printf() and UMA changes submitted by green@freebsd.org

826fe1a9d3 Remember to use stringcvt() to expand %foo% strings in registry values in
dump_defaultinfo().

a22ec80ece Deal with the duplicate sysctl leaf problem. A .inf file may contain
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.

153a70182b Support yet another variant of WinXP .INF files. 2003-12-13 08:48:35 +00:00

c7253f4fea Attempt to handle WinXP .INF files. Also, in dump_regvals(), handle
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.
