Changes since last import:
. lots of whitespace cleanups
. typo fixes (e.g. hz, compatibilty)
. fix brightness ioctl return value
. wait for int ready using DELAY() instead of tight loop
Uploaded scripts work better if they are little endian, as the
card's engine expects, so convert to le first.
Also clean up attach routine a bit (use pa_id and PCI_REVISION
instead of fetching it ourselves).
This makes the driver work on my macppc G4, it can decode and
display video and tuner input. Sound does not seem to work, but
this may be my wonky formac bktr-for-macintosh card.
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)
based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
Revert the revert. Naturally, I considered OpenBSD and FreeBSD when I fixed
the incorrect use of the spl*() interface. The change I made is _required_
for both NetBSD _and_ OpenBSD, or the code won't even COMPILE except on
i386, and it is acceptable on FreeBSD. Your revert and mod rebroke it on
OpenBSD and tangled things up on NetBSD. It made no difference on FreeBSD.
In particular, there are 2,895 uses of splx() within the FreeBSD kernel,
and only a mere 21, that's "twenty one" uses of intrmask_t, and those are
almost exclusively in the guts of the interrupt implementation, _not_ in
the _use_ of the exported spl*() functions. It's perfectly OK to `int s
= spltty()' in a portable driver in FreeBSD.
For that matter, FreeBSD (-current at least) does not even *use* spl*()
any more and stubs them all out with inlines that do _nothing_ except return
0, making intrmask_t vs int _even less_ important there than it already
was.
I think it's great that you want to start hacking on the kernel, but do
note that this is certainly the most simple of the kernel interfaces. It
just gets worse from here. Be careful out there!
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".
This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.
Tested on alpha and i386; welcome to 1.5Q
