- Move isa/ppc* to sys/dev/ppc (repo-copy)
- Add an attachment method to ppc for puc
- In puc we need to walk the chain of parents.
Still to do, is to make ppc(4) & puc(4) work on other platforms. Testers
wanted.
PR: 38372 (in spirit done differently)
Verified by: Make universe (if I messed up a platform please fix)

.Cd "device pci"

|
|
.Sh DESCRIPTION
|
|
This driver acts as a shim to connect PCI serial and parallel ports to the
|
|
.Xr sio 4
|
|
and
|
|
.Xr ppc 4
|
|
driver.
|
|
.Pp
|
|
The list of supported devices is in
|
|
.Pa sys/dev/puc/pucdata.c .
|
|
Support for new cards should be added there.
|
|
.Pp
|
|
If the
|
|
.Dv PUC_FASTINTR
|
|
option is used, the driver will try to use fast interrupts.
|
|
This should lower the interrupt latency and should be used if the
|
|
.Xr sio 4
|
|
driver reports
|
|
.Sy "silo overflow"
|
|
errors.
|
|
It cannot be used if the interrupt is shared.
|
|
.Sh SEE ALSO
|
|
.Xr sio 4
|
|
.Xr ppc 4
|
|
.Sh HISTORY
|
|
This driver took the idea from the
|
|
.Nx
|
|
.Xr puc 4
|
|
driver and still uses the same structure to describe cards, to ease exchanging
|
|
card info.
|
|
.Sh BUGS
|
|
Only serial ports are supported through the
|
|
.Xr sio 4
|
|
driver at the moment.
