places where they disagree with our list (and reality). In those cases,
I've kept the old value and added a comment. The RISC iX list stops at
ID 181 (0xb5).
two packets (just like the old psm.c driver did). And don't insist on the
first byte having bit 0x08 set.
This makes some odd trackball device work.
Thanks to Tyler Mitchell for reporting and testing.
assigned by RISCOS Ltd (and were assigned by Acorn) to be unique across all
manufacturers. This means that associating each one with a manufacturer (and
checking the manufacturer when attaching) is bogus. Thus, we don't do that
any more.
This should have the pleasant side-effect of getting APDL IDE interfaces
working, since they're just ICS ones with a different manufacturer ID.
PowerPC and provides a PCI-host bridge, interrupt controller, two com ports,
two IIC ports, a timer, and a DRAM controller.
The driver supports PCI, interrupts and com ports.
pci-pci bridge (and thus needs its interrupts "swizzled").
Formerly, pci_probe_device() assumed pci busses other than bus zero
were bridged; however, much recent x86 hardware supports multiple
primary pci busses differently -- there is a system-wide bus numbering
scheme. Now, we instead look at the (newly introduced) sc_bridgetag
value in the parent bus to figure out if there's a ppb or equivalent
in the way.
This fixed at least one case where the i386 MP branch gets interrupt
mapping wrong.
deal with such xfers, and can wedge the system with some controllers.
It's a bug to request such xfers for ATAPI, but as the request may come
from userland we have to protect against it.
Restore the reset thread, to make resetting the interface possible while
not blocking interrupts.
Make sure to throw away garbage input while the reset thread is at work
(by setting sc_enabled a bit later).
Issue a PMS_RESET command when resetting to address PR 16788.
to check if we get a RQCS_DATA_UNDERRUN - if we're an FC card, we may
not have RQCS_RU set- if it isn't set, we just lost a DATA XFR IU in the
middle of the exchange. In this case, we have to bomb out the whole xfer.
We had been getting silent data corruption before.
