4c5088e255 * Use ISA_DELETE_RESOURCE to cancel memory resource if driver clears maddr.
* Don't allow new-style isapnp devices through the compat interfaces.

1522abdd5e Don't try to allocate memory resource unless address is non-zero. 1999-05-24 18:50:41 +00:00

a3be63b3ce * Factor out the common code between the isa bus drivers for i386 and alpha.
* Re-work the resource allocation code to use helper functions in subr_bus.c.
* Add simple isa interface for manipulating the resource ranges which can be
  allocated and remove the code from isa_write_ivar() which was previously
  used for this purpose.

566643e39e Move the declaration of the interrupt type from the driver structure
to the BUS_SETUP_INTR call.

479232a2e7 GC some unused stuff relating to the old conflict checking and other lint.
Change haveseen_isadev() to something a little easier to emulate.
Store the device_t for the wrapper in isa_device.
Implement a replacement for haveseen_isadev - namely haveseen_ioport()
which takes a port size as an extra argument for a proper range check.
This (haveseen_ioport()) has not been tested, but I think it'll work.

7e381ee0b4 Back out parts of rev 1.4; making isa.c preserve the hints across a
release made it unneeded.

7ceeede80c Always reset the isa hints after releasing the resources after probe,
because the act of doing the release kills the hints(!).  A quirk of
the wrapper caused it to reset all the settings, except perhaps for the
memory address. I've tested this with a real SMC 8013EPC - which uses
shared memory addresses - it seems to work OK.

ee35d927c2 Don't do (1 << irq) to get an interrupt mask when irq = -1.

343f195b0c Fix some confusion between physical and virtual addresses when recording
the driver's choice of memory window.

2d0e5840b4 Allocate space for struct isa_device's, not for pointers thereto.
This fixes memory corruption that caused calls to address 0 here.

6182fdbda8 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.
