* Revert previous change. The magical constants can't be changedmarcel2015-06-061-1/+1
| | | | | | | | | | (easily) without having to go to other drivers to change the magical return values. This wouldn't be so bad if there were proper defines for these constants. In particular dev/acpica/acpi_pcib_pci.c returns -1000 as the probe priority and it's expected that this driver gets to attach over the common PCI bus drivers.
* Don't return -10000 as the probe priority. That's lower than whatmarcel2015-06-061-1/+1
| | | | | | | | | | | | | | BUS_PROBE_HOOVER is. Drivers like proto(4), when compiled into the kernel or preloaded, will render your system useless by virtue of attaching to your PCI busses. Return BUS_PROBE_GENERIC instead. It's just the next priority up from BUS_PROBE_HOOVER. No other meaning has been give to its use. While BUS_PROBE_DEFAULT seems like a better candidate, it's hard not to think that there must be some reason why these drivers return -10000 in the first place. Differential Revision: D2705

Interestingly, these are actually the default for quite some time (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9) since r52045) but even recently added device drivers do this unnecessarily. Discussed with: jhb, marcel - While at it, use DEVMETHOD_END. Discussed with: jhb - Also while at it, use __FBSDID.

* Next round of PCI subsystem updates:msmith2000-12-131-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Break out the /dev/pci driver into a separate file. - Kill the COMPAT_OLDPCI support. - Make the EISA bridge attach a bit more like the old code; explicitly check for the existence of eisa0/isa0 and only attach if they don't already exist. Only make one bus_generic_attach() pass over the bridge, once both busses are attached. Note that the stupid Intel bridge's class is entirely unpredictable. - Add prototypes and re-layout the core PCI modules in line with current coding standards (not a major whitespace change, just moving the module data to the top of the file). - Remove redundant type-2 bridge support from the core PCI code; the PCI-CardBus code does this itself internally. Remove the now entirely redundant header-class-specific support, as well as the secondary and subordinate bus number fields. These are bridge attributes now. - Add support for PCI Extended Capabilities. - Add support for PCI Power Management. The interface currently allows a driver to query and set the power state of a device. - Add helper functions to allow drivers to enable/disable busmastering and the decoding of I/O and memory ranges. - Use PCI_SLOTMAX and PCI_FUNCMAX rather than magic numbers in some places. - Make the PCI-PCI bridge code a little more paranoid about valid I/O and memory decodes. - Add some more PCI register definitions for the command and status registers. Correct another bogus definition for type-1 bridges.
* - Don't return early from the PCI:EISA bridge attachment, or we will losemsmith2000-12-121-1/+1
| | | | | | | | | the ISA bus. - Don't expect that a PCI:ISA bridge will have a correct class value; if we're checking PCI IDs, only depend on these. This should fix the loss of ISA on machines with PCI:EISA bridges like the AS4100.
* Next phase in the PCI subsystem cleanup.msmith2000-12-081-0/+128
- 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.
