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).
after the first found, if multiple LUNs are tried.
Change probe message to just the SCSI chip id,
similar to what the NCR driver prints.
Change the driver name to "amd" in all places.
Thanks to Nick Sayer <nsayer@quack.kfu.com> for
doing some debugging, for sending a boot message
log that shows the driver is functional, and for
pointing out there still were places that needed
the driver name to be corrected.
was found, or if there was a checksum mismatch.
This patch should allow the driver to be used with any AMD 53c974
based SCSI card, or with the AMD SCSI+Ethernet Combo Chip found on
some motherboards.
These controllers are based on the AMD 53c974, and the driver
does only support those two cards, since it checks for a Tekram
specific configuration EEPROM.
This deficiency (TM) will be fixed soon ... :)
