: New Revision: 189367
: URL: http://svn.freebsd.org/changeset/base/189367
:
: Log:
: Extend the management of PCIM_CMD_INTxDIS.
:
: We now explicitly enable INTx during bus_setup_intr() if it is needed.
: Several of the ata drivers were managing this bit internally. This is
: better handled in pci and it should work for all drivers now.
:
: We also mask INTx during bus_teardown_intr() by setting this bit.
:
: Reviewed by: jhb
: MFC after: 3 days
Note: the INTxDIS bit is new in PCI 3.0, and has no effect on earlier
devices. This should be highlighted in the comments somewhere...
