- Move PCI core code to dev/pci.
- Split bridge code out into separate modules.
- Remove the descriptive strings from the bridge drivers. If you
want to know what a device is, use pciconf. Add support for
broadly identifying devices based on class/subclass, and for
parsing a preloaded device identification database so that if
you want to waste the memory, you can identify *anything* we know
about.
- Remove machine-dependant code from the core PCI code. APIC interrupt
mapping is performed by shadowing the intline register in machine-
dependant code.
- Bring interrupt routing support to the Alpha
(although many platforms don't yet support routing or mapping
interrupts entirely correctly). This resulted in spamming
<sys/bus.h> into more places than it really should have gone.
- Put sys/dev on the kernel/modules include path. This avoids
having to change *all* the pci*.h includes.
Providing shell scripts that do nothing but load a similarly named
kernel loadable module in out of vogue.
There is no ibcs2(4) manual page, and I haven't managed to coax
anyone into contributing one based on the linux(4) manual page.
our kernel module system learned how to handle dependencies.
Providing a whole bunch of shell scripts that do nothing but load
a similarly named kernel loadable module is out of vogue.
The svr4(8) manual page has been replaced with a much better svr4(4)
page.
- Make pccbb/cardbus kld loadable and unloadable.
- Make pccbb/cardbus use the power interface from pccard instead of inventing its own.
- some other minor fixes
out of fashion. This particular case, unlike joy(8) and friends which
are just plain silly, did more than just load a kernel loadable module.
However, /etc/rc and the linux_base port were adjusted a while back to
cope with the absence of this script.
The only outstanding reason to hang on to it would have been for the
linux(8) manual page, which clued folks into the existence of the
Linuxulator. A new linux(4) was introduced a while back. It does
a much better job.
This script just isn't useful any more.
- Layout reorganisation to enhance portability. The driver now has
a relatively MI 'core' and a FreeBSD-specific layer over the top.
Since the NetBSD people have already done their own port, this is
largely just to help me with the BSD/OS port.
- Request ID allocation changed to improve performance (I'd been
considering switching to this approach after having failed to come
up with a better way to dynamically allocate request IDs, and seeing
Andy Doran use it in the NetBSD port of the driver convinced me
that I was wasting my time doing it any other way). Now we just
allocate all the requests up front.
- Maximum request count bumped back to 255 after characterisation
of a firmware issue (off-by-one causing it to crash with 256
outstanding commands).
- Control interface implemented. This allows 3ware's '3dm' utility to
talk to the controller. 3dm will be available from 3ware shortly.
- Controller soft-reset feature added; if the controller signals a
firmware or protocol error, the controller will be reset and all
outstanding commands will be retried.
