thorpej 36a4b627d0 Sigh, Jason needs to go to sleep. 2001-06-22 07:00:25 +00:00
thorpej 32e780695d Add a couple of missing p6032 bits. 2001-06-22 06:50:21 +00:00
thorpej 0c37c9e860 Check in work-in-progress of P-6032 support. This is not tested,
but is meant for back-up purposes.
2001-06-22 06:02:54 +00:00
thorpej 7f047ac2b2 Use the other DMA window (with prefetch enabled) on the P-4032
on-board Ethernet.  Suggested by Nigel Stephens <nigel@algor.co.uk>.

thorpej b440db94e8 Fill in one P-6032 snippet. 2001-06-22 04:33:26 +00:00
thorpej e4ce5f4268 A P-6032 will never have a V3 PBC -- don't include its option header. 2001-06-22 03:45:24 +00:00
thorpej b5443137f0 Only call through the function pointer if it's not NULL. 2001-06-22 01:42:20 +00:00
thorpej 1ce7119f17 More ISA interrupt rototilling. I get *some* interrupts on a:
we1 at isa0 port 0x300-0x31f iomem 0xcc000-0xcffff irq 10
we1: WD8013WC Ethernet (16-bit)
we1: Ethernet address 00:00:c0:94:f6:72

...but still nothing on the PCIC.

thorpej e0901dc354 Fix whitespace botch. 2001-06-21 18:58:18 +00:00
thorpej cc6c89106a Correct the ISA bridge irqmap. 2001-06-21 06:24:23 +00:00
thorpej f341043437 Rototill ISA interrupt code. In particular, I have remembered most
of the horror that is the 8259 PIC.

PCMCIA interrupts still not working yet, but getting closer.
2001-06-21 05:20:54 +00:00
thorpej e51a043945 Yet more interrupt cleanup -- the platform mater interrupt establish
function now just takes an "irq", which is an index into the irqmap
table for that platform.

thorpej 1d161cd563 Correct a comment. 2001-06-14 19:03:43 +00:00
thorpej fe87c9aade When the old PCI address map is in use, disable I/O space. Also disable
I/O space on PBC revs < B2.

thorpej 0ddf0d259b Don't use BUS_END to compute SYS_END. 2001-06-14 18:48:23 +00:00
thorpej 80dfaa3e5a Read the PCI memory space base and the PCI DMA window base from the
V3 PBC, and use them in the bus mem tag and the bus dma tag on the
P-4032.  This allows us to get much further when PMON has configured
the PBC using the old-style PCI address map.
2001-06-14 17:57:26 +00:00
thorpej 4c73c770ce Add MEMSIZE and ETHADDR options, so that they can be set in
the kernel config file, in case you have a buggy PMON which
doesn't provide the environment variables to the kernel.
2001-06-14 16:14:37 +00:00
thorpej defcaa8bcb Initlialize PMON after configuring the console, so we can see
debugging info.
2001-06-14 15:29:23 +00:00
thorpej 587d3ec2b4 Insert some debugging code, conditional on PMON_DEBUG. 2001-06-14 15:28:56 +00:00
thorpej 3bad583046 Oops, use the correct space tag when unmapping the RTC on the
P-4032 after calibrating the clock.

thorpej 7e59a1be7a No longer need MIPS3_5200 here. 2001-06-12 22:32:50 +00:00
thorpej be7629b7e0 Hand off intr evcnt responsiblity in a reasonable way on the 5064. 2001-06-10 09:28:26 +00:00
thorpej 7c074dc806 Check in work-in-progress of generic ISA interrupt support. The
goal here is to get the P-5064 PCMCIA slots working, and serve as
the basis for P-6032 interrupt support.

PCMCIA interrupt auto-detection not working -- more work to be
done here.

thorpej 82418a77b0 Add PCMCIA devices. 2001-06-10 08:45:09 +00:00
thorpej 1930cfd7dc Correct for a data structure change. 2001-06-10 06:17:15 +00:00
thorpej ce66bf0803 Rewrite the interrupt handling code:
- Compute the number of CPU pipeline cycles per second using the
  mc146818.
- Use the COMPARE interrupt for the hardclock interrupt.
- Collapse all interrupt priorities into a single priority, and use
  the CPU interrupt inputs to determine the interrupt source (local
  device, PCI device, ISA device, etc.)

This allows us to have interrupt sharing.

thorpej 0e82abb5de Add MIPS3_5200. 2001-06-10 05:02:33 +00:00
simonb e5bd00e48d For ports that wire up pciide in compatibility mode, have
them define __HAVE_PCIIDE_MACHDEP_COMPAT_INTR_ESTABLISH
in pci_machdep.h and pciide_map_compat_intr() only calls
pciide_machdep_compat_intr_establish() if that preprocessor
define exists.

Ports that don't need to do this no longer need to supply a
dummy function.

thorpej 2b5df8b7ff vm_page_t -> struct vm_page * 2001-06-01 19:52:54 +00:00
thorpej 71cb790fb5 Add support for the Algorithmics P-4032 board. This is totally
untested, since I have no P-4032 board, but it's no worse than
the current situation, which is "totally non-working P-4032
support in the ARC port, of all places".

thorpej f0c1fb1bb2 Initialize DDB at boot time and break into it if the "d" argument
is specified to the kernel.

XXX PMON doen't load symbols for us -- need a dbsym(1) for ELF.

thorpej af63f8979c D'oh, clear the soft interrupt bits in CAUSE *before* servicing
soft interrupts, rather than after, so that soft interrupts scheduled
by other soft interrupts don't get lost.

thorpej 16b9c60621 A port to the Algorithmics MIPS evaluation boards. We currently
support the P-5064, which has a QED RM5xxx CPU soldered on.

There is some skeletal support for the P-4032 (an older board, which
had an R4xxx CPU).  There are some placeholders for the P-6032, which
is their newest board, but no real code yet (the P-6032 has a different
PCI controller, the Algorithmics BONITO).

There are still some (apprently softintr-related) problems with the
algor kernel, but it works well-enough to self-host.

Kudos to Allegro Networks for loaning me a P-5064 board on which to do
the port.
