Dear parport maintainers,
This patch solves PCI lockups if the IRQ is in use by another driver.
Note that the EPP_sup test must disable IRQs. Otherwise the already
installed handler is called at initialization ... for ever
... until reboot.
It also allows for PCI interrupt use, specify irq=auto, detects a level
coupled INTX# and disables interrupts if necessary.
Below are the debug messages of two systems, both with a motherboard IO
controller and a PCI card. Differences are accounted for in the interrupt
handler via the our integer:
our & 1 : we are the only interrupt source
our & 2 : awaiting int and DSR nINT active -> signal good chipset
our & 4 : awaiting int and not a good chipset -> take it (... false_alarm)
our & 8 : nINT still active after reset, ints were disabled
our &0x10 : ECP ecr int expected and found, unassert PCI INTX#, as in line
with ECP register specifications.
