| | | | | | | | | | | | | | | | | | | | - 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.

| | | | | | | | | | | | | | | | | | | files which Compaq open-sourced (with a BSD license). This commit adds support for proper PCI interrupt mapping and much better support for swizzling between "standard" isa IRQs and the stdio irqs used by the t2. This also adds enabling/disabling/eoi support for AlphaServer 2100A machines. The 2100A (or lynx) interrupt hardware is is very different (and much nicer) than the 2100. Previously, only AS2100 and AS2000 machines worked. This commits also lays the groundwork for supporting ExtIO modules. These modules are essentially a second hose. This work is left unfinished pending testing on real hardware. Wilko tells me that ExtIO modules are quite rare, and may not actually exist in the wild. Obtained from: Tru64 Tested by: wilko

* - Heavyweight interrupt threads on the alpha for device I/O interrupts.jhb2000-10-051-3/+36
| | | | | | | | | | | - Make softinterrupts (SWI's) almost completely MI, and divorce them completely from the x86 hardware interrupt code. - The ihandlers array is now gone. Instead, there is a MI shandlers array that just contains SWI handlers. - Most of the former machine/ipl.h files have moved to a new sys/ipl.h. - Stub out all the spl*() functions on all architectures.

* * Completely rewrite the alpha busspace to hide the implementation fromdfr2000-08-281-243/+16
| | | | | | | | | | | | 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.
* Add AlphaServer 2000 (demi-sable), 2100 (sable), and 2100A (lynx) support.gallatin2000-05-281-0/+658
Only PCI and on-board ISA peripherials are supported at this time. This support has been only lightly tested due to a lack of response to my call for testers on the freebsd-alpha mailing list. It works quite well on the one AS2100 on which it has been tested, but it may not work on an AS2100A and should therefore be regarded as experimental.
