The loongon2f+cs5526+jmicron PATA->SATA bridge cause an interresting issue: 1) because the CS5536 is not associated with a x86 CPU, interrupts are not ack'ed as it expects so interrupts cannot configured as edge-triggered (as is expected for a PCIIDE in compat mode) 2) the PATA->SATA bridge ignores the WDC_IDS (interrupt disable bit) so the PATA IRQ line gets asserted when resetting or running some polled commands. It also wrongly asserts IRQ when the (nonexistent) slave device is selected 2) wouldn't be an issue with edge-triggered interrupt because we would get a spurious interrupt and continue operation, a new interrupt only shows up when the PATA IRQ line goes low and high again. But because of 1), we get an unclearable interrupt instead, and the system loops on the interrupt handler. To workaround this, introduce a WDC_NO_IDS compile option which runs all polled commands (including reset) at splbio() and without sleeps, so that the controller's interrupt is effectively disabled and won't be reenabled before the interrupt can be cleared. The conditions triggering this problem are speficic enough to handle this via a compile-time option; no need for a run-time (e.g. a config(9), device property or callback to disable interrupts) solution.

# $NetBSD: LOONGSON,v 1.2 2011/08/27 17:05:57 bouyer Exp $
Add loongson support to evbmips, based on the OpenBSD loongson port and the existing evbmips/gdium support. This has been tested on a lemote fuloong device (boots multiuser), should also support other lemote devices (maybe with minor adjustments, or adding missing drivers). There is some gdium support here too, but it may not be yet complete (someone with a gdium would need to have a look, hi macallan@ :) loongson kernels are 64bits only: the loongson2f has ressources located above the 2Gb physical address, and it's much easier to access it using XKPHYS than trying to make it fit in the limited 32bit kernel virtual space.

# LOONGSON machine description file

# This machine description file is used to generate the default NetBSD
# kernel. The generic kernel does not include all options, subsystems
# and device drivers, but should be useful for most applications.
#
# The machine description file can be customised for your specific
# machine to reduce the kernel size and improve its performance.
#
# For further information on compiling NetBSD kernels, see the config(8)
# man page.
#
# For further information on hardware support for this architecture, see
# the intro(4) man page. For further information about kernel options
# for this architecture, see the options(4) man page. For an explanation
# of each device driver in this file see the section 4 man page for the
# device.

# IDE drives
# Flags are used only with controllers that support DMA operations

# UltraDMA mode. For each set of four bits, the 3 lower bits define the mode
# to use, and the last bit must be 1 for this setting to be used.
