* Allow device hints to wire the unit numbers of devices.John Baldwin2008-11-181-0/+3
| | | | | | | | | | | | | | | | | | | | | | | - An "at" hint now reserves a device name. - A new BUS_HINT_DEVICE_UNIT method is added to the bus interface. When determining the unit number of a device, this method is invoked to let the bus driver specify the unit of a device given a specific devclass. This is the only way a device can be given a name reserved via an "at" hint. - Implement BUS_HINT_DEVICE_UNIT() for the acpi(4) and isa(4) bus drivers. Both of these busses implement this by comparing the resources for a given hint device with the resources enumerated by ACPI/PnPBIOS and wire a unit if the hint resources are a subset of the "real" resources. - Use bus_hinted_children() for adding hinted devices on isa(4) busses now instead of doing it by hand. - Remove the unit kludging from sio(4) as it is no longer necessary.

* MFp4:Warner Losh2008-11-021-2/+8
| | | | | | | | | Make the ISA bus keep track of more PNP details. Plus a minor style fix while I'm here. More could be done here, but except for some SBCs that don't have ACPI, there's limited value to anybody in doing so. Notes: svn path=/head/; revision=184564

* PNP BIOS devices are fundamentally different than ISA PNP devices.Warner Losh2004-12-071-8/+9
| | | | | | | | | | These devices should be probed first because they are at fixed locations and cannot be turned off. ISA PNP devices, on the other hand, can be turned off and often can be flexible in the resources they use. Probe them last, as always. Notes: svn path=/head/; revision=138506

* - Make the isab devclass global to allow for multiple ISA bridge drivers.John Baldwin2003-07-081-0/+5
| | | | | | | | | | - Factor out code common to all ISA bridge drivers attach methods into a isab_attach() function. - Rename the PCI-ISA bridge driver's attach function to pci_isab_attach() and have it call isab_attach(). Notes: svn path=/head/; revision=117337

The accessor function is still isa_get_msize(). Notes: svn path=/head/; revision=105139

* Rework the ISA PnP driver pnp and the PnP resource parser to fixKazutaka YOKOTA2001-09-051-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | the following bugs. - When constructing a resource configuration, respect the order in which resource descriptors are read, in order to establish the correct mapping between the descriptors and configuration registers.

"Clarifications to the Plug and Play ISA Specification, Version 1.0a", Sec 6.2.1, Dec. 10, 1994. - Do not ignore null (empty) descriptors; they are valid descriptors acting as filler. "Clarifications to the Plug and Play ISA Specification, Version 1.0a", Sec 6.2.1. - Correctly set up logical device configuration registers for null resources. "Clarifications to the Plug and Play ISA Specification, Version 1.0a" - Handle null resources properly in the resource allocator for the ISA bus. Notes: svn path=/head/; revision=83051

* Stop isadma from abusing the B_READ, B_RAW and B_WRITE flags.Poul-Henning Kamp2000-03-131-0/+3

* Newbus-ify the USR Sportster TA Intern driver.Gary Jennejohn2000-02-211-1/+1
| | | | | | | | | | | | | | | | | | | | | Enable the driver in sys/conf/files.i386. In isa/isavar.h increase ISA_NPORT from 32 to 50. This is required because this brain-damaged card maps 49 (!) port ranges. This does not have a negative impact because this value only specifies the maximum number of entries in a linked list and not the size of an array which is allocated in all drivers. The register/fifo access routines were not newbus-ified because 1) I knew that the old code worked and is simpler and more efficient 2) the if_ed driver does something similar and 3) the newbus macros collapse to inb/outb anyway.

* Stage 1 of a cleanup of the i386 interrupt registration mechanism.Peter Wemm1999-04-211-3/+3
| | | | | | | | | | Interrupts under the new scheme are managed by the i386 nexus with the awareness of the resource manager. There is further room for optimizing the interfaces still. All the users of register_intr()/intr_create() should be gone, with the exception of pcic and i386/isa/clock.c. Notes: svn path=/head/; revision=45897
* Bring the 'new-bus' to the i386. This extensively changes the way thePeter Wemm1999-04-161-2/+5
| | | | | | | | | | | | | | | | | | | | | 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.

Garrett has some much cleaner drivers which should be more easily shared between i386 and alpha. This has only been tested on cia based machines. It should work on lca and apecs but I might have broken something. Notes: svn path=/head/; revision=41181
