itojun dc4bf37abf support new quirk bits on debug output 2003-08-18 05:39:07 +00:00
itojun c2ab035d77 - check HDRTYPE early, and ignore if it is not supported (n > 2).
- defer access to interrupt configuration register, as its existence depends on
  HDRTYPE.
- add "skip particular funtion in multifunction device" functionality
  to quirk table.
- add GEODE/NS SC1100 quirk (now boots on soekris Net4801).

fvdl 7dd7f8baa2 Handle 64bit DMA addresses on PCI for platforms that can (currently only
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.

thorpej d1ad2ac4f2 Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver.  The cfdriver is then looked
up in a list which is built at run-time.

tshiozak fe6f56bfb7 add support for the per-device power management capability.
int pci_set_powerstate(pci_chipset_tag_t pc, pcitag_t tag, int newstate)
	set power state of the device to newstate.
int pci_get_powerstate(pci_chipset_tag_t pc, pcitag_t tag)
	get current power state of the device.

In the future, these functions will be used for ACPI support.

sommerfeld ce6cc5672c Add "pa_rawintrpin" containing unswizzled interrupt pin to pci_attach_args. 2002-05-18 21:40:41 +00:00
sommerfeld 314ef13c23 In pci_probe_device(), correct test for whether the device is behind a
pci-pci bridge (and thus needs its interrupts "swizzled").

Formerly, pci_probe_device() assumed pci busses other than bus zero
were bridged; however, much recent x86 hardware supports multiple
primary pci busses differently -- there is a system-wide bus numbering
scheme.  Now, we instead look at the (newly introduced) sc_bridgetag
value in the parent bus to figure out if there's a ppb or equivalent
in the way.

This fixed at least one case where the i386 MP branch gets interrupt
mapping wrong.

thorpej 86b4df33e7 Make sure pa.pa_bus is initialized. (Thanks, uwe!) 2002-05-16 01:03:05 +00:00
thorpej 204183c0fa * Add "pcitag_t *pba_bridgetag" to pci_attach_args. This is set to
NULL for root PCI busses.  For busses behind a bridge, it points to
  a persistent copy of the bridge's pcitag_t.  This can be very useful
  for machine-dependent PCI bus enumeration code.
* Implement a machine-dependent pci_enumerate_bus() for sparc64 which
  uses OFW device nodes to enumerate the bus.  When a PCI bus that is
  behind a bridge is attached, pci_attach_hook() allocates a new PCI
  chipset tag for the new bus and sets it's "curnode" to the OFW node
  of the bridge.  This is used as a starting point when enumerating
  that bus.  Root busses get the OFW node of the host bridge (psycho).
* Garbage-collect "ofpci" and "ofppb" from the sparc64 port.

thorpej dada8613e1 Let machine-dependent code specify how to enumerate the bus.
Currently, everyone uses pci_enumerate_bus_generic().

thorpej 40116f53dd Put back __PCI_BUS_DEVORDER for now. 2002-05-15 18:39:47 +00:00
thorpej 7c86eb62bc Split the code that enumerates the PCI bus and that actually probes
for a device into two functions:

* pci_probe_device() actually probes/attaches the device specified
  by the provide pcitag_t.

* pci_enumerate_bus() enumerates the bus, and calls pci_probe_device()
  for each device on the bus.  A pci_enumerate_bus_generic() is provided
  which implements the old method of doing this: If something found at
  dev0/func0, determine number of functions and probe each one.

  Machine-dependent code will be able to specify the bus enumeration
  routine in the future.

thorpej 397a84f51a Fix the semantics of __PCI_DEV_FUNCORDER so that they're actually useful:
If __PCI_DEV_FUNCORDER is defined, don't do the song-and-dance to check if
a device is multi-function; machdep code is going to tell us exactly which
functions to probe.

Note this required changing how pci_func_devorder() works in the
sparc64 PCI machdep code; now the "curnode" is assumed to point
to the bus, rather than some function (typically 0) on the device,
just as pci_bus_devorder() makes that assumption.

All this should allow the PCI code to actually locate the second
HME device on a Sun Netra t1, which is at 3,1 -- previously, the
PCI code would have missed it because there is no device at 3,0.

(Sun deserves a brick to the head for this one -- this seems clearly
out of line with the PCI spec.)

thorpej 23763f2f28 Add an ioctl interface to the PCI bus. Add ioctls to read/write
PCI configuration space registers, and to fetch bus info.

fvdl ac50343c76 Add a pci_find_device function, to find a PCI device using a match
function on all (probed) PCI buses:

int     pci_find_device(struct pci_attach_args *pa,
                        int (*match)(struct pci_attach_args *));

The pci_attach_args structure pointed to by pa is filled in if the
device is found, and 1 is returned. Otherwise 0 is returned.

This function is, unfortunately, needed by the i810 agp code. It's
also of use for LKMs.

Also frob pci_probe_bus to take 2 extra args when used by pci_find_device.

mrg 11524b8374 allow pci_bus_maxdevs() to be replaced with pci_bus_devorder() and
pci_dev_funcorder() that have the following signatures:

int pci_bus_devorder(pci_chipset_tag_t pc, int bus, char list[32]);
int pci_dev_funcorder(pci_chipset_tag_t pc, int bus, int device, char list[8]);

they control the order of PCI bus probe at the device and function level,
by filling in a value from 0 to 31 for pci_bus_devorder() or 0 to 7 for
pci_dev_funcorder, with a value of -1 to signify no more entries.


when device properties arrive, these will be replaced with some facility
based on properties (design/implementation unknown currently.)

cgd 00f7a2d476 if the PCI_CONFIG_DUMP option is defined, set the patchable
pci_config_dump variable to 1.  otherwise, it gets set to 0.  If
that's set, when configuring PCI devices spew the very verbose
configuration space header dump that was previously "#if 0"'d.
If you use this option, or patch the variable to 1, it's strongly
encouraged that you have used the MSGBUFSIZE option to enlarge the
kernel message buffer.

cgd 86585ca518 use the new PCI 'quirks' mechanism to help determine the number
of functions on a given device.  Also, clean up the #if 0'd
major-debugging-spew code so that it's all one piece, so that
it's a bit prettier, and so that it prints out quirk information.
1998-05-31 06:05:28 +00:00
cgd 9991233636 add an #if 0'd chunk which will pci_conf_print() every device (spews
lots of data, e.g. ~18k on a PCI system with few add-in devices; use
with MSGBUFSIZE=...).  Useful to have here so that people who want as
much data about the PCI configuration in a machine can get it without
having to craft their own code.  Also, clean up a few of the other
#if 0'd printfs.
