Completely replace the PCI bus driver code to make it better reflect reality. There will be a new call interface, but for now the file pci_compat.c (which is to be deleted, after all drivers are converted) provides an emulation of the old PCI bus driver functions. The only change that might be visible to drivers is, that the type pcici_t (which had been meant to be just a handle, whose exact definition should not be relied on), has been converted into a pcicfgregs* . The Tekram AMD SCSI driver bogusly relied on the definition of pcici_t and has been converted to just call the PCI drivers functions to access configuration space register, instead of inventing its own ... This code is by no means complete, but assumed to be fully operational, and brings the official code base more in line with my development code. A new generic device descriptor data type has to be agreed on. The PCI code will then use that data type to provide new functionality: 1) userconfig support 2) "wired" PCI devices 3) conflicts checking against ISA/EISA 4) maps will depend on the command register enable bits 5) PCI to Anything bridges can be defined as devices, and are probed like any "standard" PCI device. The following features are currently missing, but will be added back, soon: 1) unknown device probe message 2) suppression of "mirrored" devices caused by ancient, broken chip-sets This code relies on generic shared interrupt support just commited to kern_intr.c (plus the modifications of isa.c and isa_device.h).

Next round of PCI subsystem updates: - 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.

Bring the 'new-bus' to the i386. This extensively changes the way the i386 platform boots, it is no longer ISA-centric, and is fully dynamic. Most old drivers compile and run without modification via 'compatability shims' to enable a smoother transition. eisa, isapnp and pccard* are not yet using the new resource manager. Once fully converted, all drivers will be loadable, including PCI and ISA. (Some other changes appear to have snuck in, including a port of Soren's ATA driver to the Alpha. Soren, back this out if you need to.) This is a checkpoint of work-in-progress, but is quite functional. The bulk of the work was done over the last few years by Doug Rabson and Garrett Wollman. Approved by: core

#include "opt_bus.h"
Added a bit of missing functionality to make this work correctly on a wider variety of systems. Include the deivers from pci_intel.c in pci_config.c (I hope this is what was intended; my system works ok). Use pmap_mapdev(). Automatically map any large linear frame buffers or whatnot in VGA-style devices which ordinarily would not have their own drivers, and don't call not_supported() for them. (This shuts up complaints about my Matrox card.) Include the beginnings of what could eventually become dynamically-loadable PCI devices. Allow for the possibility of PCI devices simply providing a PCI veneer over an existing ISA device, and shut up about them, too. Make autoconfiguration text conform more to the style of other supported buses.

#include <sys/param.h>
#include <sys/systm.h>
Submitted by: Wolfgang Stanglmeier <wolf@dentaro.GUN.de> Bug fixed, that caused system hang on first interrupt on some motherboards. New version of PCI bus configuration code, now supports dynamic interrupt configuration (using BIOS supplied values). NCR SCSI and DEC Ethernet driver patched to use this feature. *** Remove PCI IRQ specifications from your kernel config file ! ***
1994-10-12 02:33:23 +00:00
#include <sys/malloc.h>
Replace the pcidevice_set linker set based configuration mechanism for old style pci drivers with a simple one-line change to use a module that registers itself under new-bus and should in theory enable just about all of the pci drivers to be loadable (kldload and loader(8)) but without having the impact of converting the APIs yet. This also fixes the problem of having undefined variables when only new-style pci drivers are present.
1999-04-24 19:59:20 +00:00
#include <sys/module.h>
Next phase in the PCI subsystem cleanup. - 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.

Encapsulate the old PCI compatability support and APIs completely under "options COMPAT_OLDPCI". This option already existed, but now also tidies up the declarations in #include <pci/pci*.h>. It is amazing how much stuff was using the old pre-FreeBSD 3.x names and going silently undetected.
2000-05-28 16:35:57 +00:00
#include <sys/pciio.h>
Use the pci.c code wherever possible, rather than copying all the pci code into cardbus and s/pci/cardbus. This exposes a few pci_* functions that are now static. This work is similar to work Justin posted to the mobile list about a year or two ago, which I have neglected since then. This is a subset of his current work with the multiple inheritance newbus architecutre. When completed, that will eliminate the need for pci/pci_private.h. Similar work is needed for the cardbus_cis and pccard_cis code as well.

* Completely rewrite the alpha busspace to hide the implementation from the drivers. * Remove legacy inx/outx support from chipset and replace with macros which call busspace. * Rework pci config accesses to route through the pcib device instead of calling a MD function directly. With these changes it is possible to cleanly support machines which have more than one independantly numbered PCI busses. As a bonus, the new busspace implementation should be measurably faster than the old one.

Various changes to make it easier to subclass the PCI bus device. - Make the pci devclass a global variable. - Add child devices in pci_attach() instead of pci_probe(). Change pci_probe() to just check for a valid bus number from the associated bridge and return -1000 if successful. This allows subclasses of the PCI bus driver to override the generic driver. - Move the code to load the vendor data into its own public function. Really though, doing this at attach is just plain wrong. This should really be done in the module load routine instead. As a side effect, the 'busno' variable in pci_attach() is now no longer static (minor bug that was harmless so far.) - Change pci_add_children() to take an extra argument that is the size of the device info structure passed to pci_read_device() and make it public so subclasses of the PCI bus can call it in their attach routines. - Move the bits to attach a probed PCI child to a PCI bus into a global pci_add_child() function. This will allow subclasses that can detect a PCI device not found in the normal PCI probe to add those devices in their own attach routine. (I have seen this in the ACPI tree on my laptop for example.) As a side effect, change the static function pci_add_resources() to get the busno, slot, and func from the passed in dinfo structure instead of requiring them as function arguments.

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.

Various changes to make it easier to subclass the PCI bus device. - Make the pci devclass a global variable. - Add child devices in pci_attach() instead of pci_probe(). Change pci_probe() to just check for a valid bus number from the associated bridge and return -1000 if successful. This allows subclasses of the PCI bus driver to override the generic driver. - Move the code to load the vendor data into its own public function. Really though, doing this at attach is just plain wrong. This should really be done in the module load routine instead. As a side effect, the 'busno' variable in pci_attach() is now no longer static (minor bug that was harmless so far.) - Change pci_add_children() to take an extra argument that is the size of the device info structure passed to pci_read_device() and make it public so subclasses of the PCI bus can call it in their attach routines. - Move the bits to attach a probed PCI child to a PCI bus into a global pci_add_child() function. This will allow subclasses that can detect a PCI device not found in the normal PCI probe to add those devices in their own attach routine. (I have seen this in the ACPI tree on my laptop for example.) As a side effect, change the static function pci_add_resources() to get the busno, slot, and func from the passed in dinfo structure instead of requiring them as function arguments. Tested on: i386, alpha, ia64, sparc64

* Completely rewrite the alpha busspace to hide the implementation from the drivers. * Remove legacy inx/outx support from chipset and replace with macros which call busspace. * Rework pci config accesses to route through the pcib device instead of calling a MD function directly. With these changes it is possible to cleanly support machines which have more than one independantly numbered PCI busses. As a bonus, the new busspace implementation should be measurably faster than the old one.

Next phase in the PCI subsystem cleanup. - 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.

Completely replace the PCI bus driver code to make it better reflect reality. There will be a new call interface, but for now the file pci_compat.c (which is to be deleted, after all drivers are converted) provides an emulation of the old PCI bus driver functions. The only change that might be visible to drivers is, that the type pcici_t (which had been meant to be just a handle, whose exact definition should not be relied on), has been converted into a pcicfgregs* . The Tekram AMD SCSI driver bogusly relied on the definition of pcici_t and has been converted to just call the PCI drivers functions to access configuration space register, instead of inventing its own ... This code is by no means complete, but assumed to be fully operational, and brings the official code base more in line with my development code. A new generic device descriptor data type has to be agreed on. The PCI code will then use that data type to provide new functionality: 1) userconfig support 2) "wired" PCI devices 3) conflicts checking against ISA/EISA 4) maps will depend on the command register enable bits 5) PCI to Anything bridges can be defined as devices, and are probed like any "standard" PCI device. The following features are currently missing, but will be added back, soon: 1) unknown device probe message 2) suppression of "mirrored" devices caused by ancient, broken chip-sets This code relies on generic shared interrupt support just commited to kern_intr.c (plus the modifications of isa.c and isa_device.h).

Completely replace the PCI bus driver code to make it better reflect reality. There will be a new call interface, but for now the file pci_compat.c (which is to be deleted, after all drivers are converted) provides an emulation of the old PCI bus driver functions. The only change that might be visible to drivers is, that the type pcici_t (which had been meant to be just a handle, whose exact definition should not be relied on), has been converted into a pcicfgregs* . The Tekram AMD SCSI driver bogusly relied on the definition of pcici_t and has been converted to just call the PCI drivers functions to access configuration space register, instead of inventing its own ... This code is by no means complete, but assumed to be fully operational, and brings the official code base more in line with my development code. A new generic device descriptor data type has to be agreed on. The PCI code will then use that data type to provide new functionality: 1) userconfig support 2) "wired" PCI devices 3) conflicts checking against ISA/EISA 4) maps will depend on the command register enable bits 5) PCI to Anything bridges can be defined as devices, and are probed like any "standard" PCI device. The following features are currently missing, but will be added back, soon: 1) unknown device probe message 2) suppression of "mirrored" devices caused by ancient, broken chip-sets This code relies on generic shared interrupt support just commited to kern_intr.c (plus the modifications of isa.c and isa_device.h).

Two minor changes to the code that builds the pci map array: 1) Stop at the first map register that contains a zero value. 2) When testing for the map size work up from low values, since this works around a bug in some BusLogic SCSI card, which has the 16 upper port base address bits hardwired to zero.

Update PCI bus code from my current sources: - always use pci_conf_read() and pci_conf_write().

Completely new PCI code: 1) Supports PCI to PCI bridge devices (and tries to initialise them, even if the BIOS is brain dead). 2) Supports shared PCI interrupts. Interrupt handlers now MUST return '0' if they found nothing to do, '1' otherwise. New features tested with i486 systems based on the Intel Saturn and a DEC 4channel Ethernet card only, but expected to work on most systems. The option PCI_REMAP has been removed !

Next round of PCI subsystem updates: - 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.

Use the pci.c code wherever possible, rather than copying all the pci code into cardbus and s/pci/cardbus. This exposes a few pci_* functions that are now static. This work is similar to work Justin posted to the mobile list about a year or two ago, which I have neglected since then. This is a subset of his current work with the multiple inheritance newbus architecutre. When completed, that will eliminate the need for pci/pci_private.h. Similar work is needed for the cardbus_cis and pccard_cis code as well.

Next round of PCI subsystem updates: - 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.

Completely replace the PCI bus driver code to make it better reflect reality. There will be a new call interface, but for now the file pci_compat.c (which is to be deleted, after all drivers are converted) provides an emulation of the old PCI bus driver functions. The only change that might be visible to drivers is, that the type pcici_t (which had been meant to be just a handle, whose exact definition should not be relied on), has been converted into a pcicfgregs* . The Tekram AMD SCSI driver bogusly relied on the definition of pcici_t and has been converted to just call the PCI drivers functions to access configuration space register, instead of inventing its own ... This code is by no means complete, but assumed to be fully operational, and brings the official code base more in line with my development code. A new generic device descriptor data type has to be agreed on. The PCI code will then use that data type to provide new functionality: 1) userconfig support 2) "wired" PCI devices 3) conflicts checking against ISA/EISA 4) maps will depend on the command register enable bits 5) PCI to Anything bridges can be defined as devices, and are probed like any "standard" PCI device. The following features are currently missing, but will be added back, soon: 1) unknown device probe message 2) suppression of "mirrored" devices caused by ancient, broken chip-sets This code relies on generic shared interrupt support just commited to kern_intr.c (plus the modifications of isa.c and isa_device.h).

Completely new PCI code: 1) Supports PCI to PCI bridge devices (and tries to initialise them, even if the BIOS is brain dead). 2) Supports shared PCI interrupts. Interrupt handlers now MUST return '0' if they found nothing to do, '1' otherwise. New features tested with i486 systems based on the Intel Saturn and a DEC 4channel Ethernet card only, but expected to work on most systems. The option PCI_REMAP has been removed !

Next round of PCI subsystem updates: - 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.

Use the pci.c code wherever possible, rather than copying all the pci code into cardbus and s/pci/cardbus. This exposes a few pci_* functions that are now static. This work is similar to work Justin posted to the mobile list about a year or two ago, which I have neglected since then. This is a subset of his current work with the multiple inheritance newbus architecutre. When completed, that will eliminate the need for pci/pci_private.h. Similar work is needed for the cardbus_cis and pccard_cis code as well.

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.

Bring the 'new-bus' to the i386. This extensively changes the way the i386 platform boots, it is no longer ISA-centric, and is fully dynamic. Most old drivers compile and run without modification via 'compatability shims' to enable a smoother transition. eisa, isapnp and pccard* are not yet using the new resource manager. Once fully converted, all drivers will be loadable, including PCI and ISA. (Some other changes appear to have snuck in, including a port of Soren's ATA driver to the Alpha. Soren, back this out if you need to.) This is a checkpoint of work-in-progress, but is quite functional. The bulk of the work was done over the last few years by Doug Rabson and Garrett Wollman.

Unconditionally turning on the I/O and memory enable bits in the PCI command register is too aggressive. Revert to the previous behaviour, but leave the new behaviour available as an undocumented option. It's not clear what the Right, Right Thing is to do here, but the more conservative approach is safer.

Make PCI_ENABLE_IO_MODES a sysctl hw.pci.enable_io_modes. It can also be set at boot time. It defaults to 1 now since it can be set in the boot loader. If this proves unwise, we can reset it to defaulting to 0.

If a base address register has been set up by the BIOS, but the relevant enable bit hasn't been set in the command register, set the bit and honour the register. It seems that quite a few lazy BIOS writers aren't bothering to do this, which upsets the existing code and causes us to miss out on properly-configured devices.

Various changes to make it easier to subclass the PCI bus device. - Make the pci devclass a global variable. - Add child devices in pci_attach() instead of pci_probe(). Change pci_probe() to just check for a valid bus number from the associated bridge and return -1000 if successful. This allows subclasses of the PCI bus driver to override the generic driver. - Move the code to load the vendor data into its own public function. Really though, doing this at attach is just plain wrong. This should really be done in the module load routine instead. As a side effect, the 'busno' variable in pci_attach() is now no longer static (minor bug that was harmless so far.) - Change pci_add_children() to take an extra argument that is the size of the device info structure passed to pci_read_device() and make it public so subclasses of the PCI bus can call it in their attach routines. - Move the bits to attach a probed PCI child to a PCI bus into a global pci_add_child() function. This will allow subclasses that can detect a PCI device not found in the normal PCI probe to add those devices in their own attach routine. (I have seen this in the ACPI tree on my laptop for example.) As a side effect, change the static function pci_add_resources() to get the busno, slot, and func from the passed in dinfo structure instead of requiring them as function arguments.

Next round of PCI subsystem updates: - 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.

Various changes to make it easier to subclass the PCI bus device. - Make the pci devclass a global variable. - Add child devices in pci_attach() instead of pci_probe(). Change pci_probe() to just check for a valid bus number from the associated bridge and return -1000 if successful. This allows subclasses of the PCI bus driver to override the generic driver. - Move the code to load the vendor data into its own public function. Really though, doing this at attach is just plain wrong. This should really be done in the module load routine instead. As a side effect, the 'busno' variable in pci_attach() is now no longer static (minor bug that was harmless so far.) - Change pci_add_children() to take an extra argument that is the size of the device info structure passed to pci_read_device() and make it public so subclasses of the PCI bus can call it in their attach routines. - Move the bits to attach a probed PCI child to a PCI bus into a global pci_add_child() function. This will allow subclasses that can detect a PCI device not found in the normal PCI probe to add those devices in their own attach routine. (I have seen this in the ACPI tree on my laptop for example.) As a side effect, change the static function pci_add_resources() to get the busno, slot, and func from the passed in dinfo structure instead of requiring them as function arguments.

Next phase in the PCI subsystem cleanup. - 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.

Use the pci.c code wherever possible, rather than copying all the pci code into cardbus and s/pci/cardbus. This exposes a few pci_* functions that are now static. This work is similar to work Justin posted to the mobile list about a year or two ago, which I have neglected since then. This is a subset of his current work with the multiple inheritance newbus architecutre. When completed, that will eliminate the need for pci/pci_private.h. Similar work is needed for the cardbus_cis and pccard_cis code as well.

Implement the BUS_PROBE_NOMATCH method for the PCI bus. This function is called for each device for which no driver was found. Output is similar to the eisa_probe_nomatch() function but with the added benefit of displaying the assigned IRQ (since PCI gives us this information up front.) Output is like so: pci0: unknown card CPQ0508 (vendor=0x0e11, dev=0x0508) at 11.0 irq 9 pci0: unknown card DFZ0508 (vendor=0x10da, dev=0x0508) at 11.0 irq 9 pci0: unknown card DBL0508 (vendor=0x104c, dev=0x0508) at 11.0 irq 9 pci0: unknown card DDM0011 (vendor=0x108d, dev=0x0011) at 11.0 irq 9 I'm not happy with the 3 lines of macro cruft that got added but I consider it a temporary annoyance as those bits will be moved to some place where PCI, EISA and ISAPNP code will be able to use them. (Not surprisingly, this message is longer than the code in question.) Reviewed by: peter, dfr

Next phase in the PCI subsystem cleanup. - 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.

Move the pretty printing of the description for USB controllers to pci_probe_nomatch, so it won't be in the way when loading USB as a module. The reason for them being there in the first place is that every motherboard comes with USB kit and this way it looks more pretty (peter). The real solution will be to define some method of detaching a driver after it has attached.

Implement the BUS_PROBE_NOMATCH method for the PCI bus. This function is called for each device for which no driver was found.

Next phase in the PCI subsystem cleanup. - 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.

Fixed the type of some ivar access functions. Ivars have type uintptr_t, not u_long. On i386's with 64-bit longs, returning u_longs indirectly in (more than) the space reserved for uintptr_t's tended to corrupt the previous frame pointer in the stack frame, so it was not easy to debug. The type mismatches are hidden by the bogus cast in DEVMETHOD().

Use the pci.c code wherever possible, rather than copying all the pci code into cardbus and s/pci/cardbus. This exposes a few pci_* functions that are now static. This work is similar to work Justin posted to the mobile list about a year or two ago, which I have neglected since then. This is a subset of his current work with the multiple inheritance newbus architecutre. When completed, that will eliminate the need for pci/pci_private.h. Similar work is needed for the cardbus_cis and pccard_cis code as well.

Bring the 'new-bus' to the i386. This extensively changes the way the i386 platform boots, it is no longer ISA-centric, and is fully dynamic. Most old drivers compile and run without modification via 'compatability shims' to enable a smoother transition. eisa, isapnp and pccard* are not yet using the new resource manager. Once fully converted, all drivers will be loadable, including PCI and ISA. (Some other changes appear to have snuck in, including a port of Soren's ATA driver to the Alpha. Soren, back this out if you need to.) This is a checkpoint of work-in-progress, but is quite functional. The bulk of the work was done over the last few years by Doug Rabson and Garrett Wollman.

STAILQ_INIT(&pci_devq);
Next round of PCI subsystem updates: - 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.
