cgd e9abc8540f remove all traces of __BROKEN_INDIRECT_CONFIG (except in shared drivers) 1996-12-08 00:22:08 +00:00
cgd 8b6a32d1c1 update these so they compile whether or not __BROKEN_INDIRECT_CONFIG
is defined.
1996-12-05 01:39:27 +00:00
cgd 30b636bd09 implement bus_space_copy_*(). 1996-12-02 22:19:32 +00:00
cgd 256cf234a1 move barrier operation definition closer to the top of the bus space ops
structure.  In the implementations, allow the barrier op to be inlined.
1996-12-02 07:07:18 +00:00
cgd 54ba942f79 implement bus_space_set_multi_* and bus_space_set_region_* operations. 1996-12-02 06:46:49 +00:00
cgd e6bafb00d6 declare the single-datum read and write methods as inline, so that
the multi and region methods can inline them.

cgd 366a586e85 if we're going to do a real match (we are), ahve to special-case console 1996-11-27 01:20:26 +00:00
cgd 97927bdd99 update for new extent management code. Most importantly, we can't call
the chipset space init functions multiple times, since that would clobber
extent allocations made between the two calls.  Also, deal with the
fact that the APECS and LCA no longer shared common chipset functions.

cgd 77baf28d70 update for new extent management code. Most importantly, we can't call
the chipset space init functions multiple times, since that would clobber
extent allocations made between the two calls.

cgd 7a1799b561 update for new extent management code, and for apecs/lca space access fn split 1996-11-25 03:49:36 +00:00
cgd 608a9f3065 update for new extent management code 1996-11-25 03:49:11 +00:00
cgd 6d7b2d82a7 make eb164 interrupts actually work. 1996-11-25 03:47:05 +00:00
cgd 8b50c9af38 reimplement, so that it works with the new extent mapping code. 1996-11-25 03:46:07 +00:00
cgd fe6262c3c0 split the APECS and LCA bus memory and I/O functions. Most of them still do
the same things, but the extent maps have to be managed differently,
since the two chipsets provide different memory and I/O region mapping
possibilities.
1996-11-25 03:42:09 +00:00
cgd 1a45dbd671 update these to set up and use extents to map i/o space, and sparse and
dense memory.
1996-11-25 03:37:23 +00:00
cgd 8c007e0e48 use set_pci_isa_bridge_callback() to delay ISA/EISA bus attachment until
after PCI tree has been completely probed.
1996-11-25 03:15:24 +00:00
cgd abf0b7c010 deal with the fact that apparently-common revisions of EB164 firmware
don't machine check when a PCI Master Abort is signalled.  This can
happen, for instance, when configuration space for a device that isn't
present is examined.  When this is detected, act like we normally would
when machine checks are posted while examining nonexistant devices.
1996-11-23 06:46:50 +00:00
cgd ff523f9080 fix HAE_MEM_REG3_START definition (shift was incorrect). Add CIA_CSR_CIA_ERR
register definition.  (should define bits in CIA_CSR_CIA_ERR, but haven't
done that yet.)
1996-11-23 06:42:55 +00:00
cgd 574633aea2 add definitions for LCA_IOC_HAE contents. Add a REGVAL64 macro, like
REGVAL but good for 64-bit chipset registers.
1996-11-23 06:41:00 +00:00
cgd 335c1af878 move probe and setup code into common functions. always probe (i.e.
even if PCI and the IDs are right), just for sanity, before declaring
success.  Split the single 0x3b0 -> 0x3df allocation into three seperate
ones: 0x3b0 -> 0x3bc (leaving the 4 ports available for lpt),
0x3c0 -> 0x3cf, and 0x3d0 -> 0x3df.  The former chunk has to be split
off if the lpt can exist there, and it's sort-of pretty to have each
group (based on second hex digit) have its own handle.

cgd 7b52699cfd catch up with wscons frame buffer attachment, mmap, and ioctl
interface changes.

cgd f3415af098 update for VGA-related changes 1996-11-19 04:57:32 +00:00
cgd bf371611ab fix spelling error 1996-11-19 04:49:21 +00:00
cgd 2c43c05bc2 replace old PCI VGA driver with a common VGA back-end and ISA and PCI
front-ends.  Unfortunately, because of the way ISA and PCI are currently
probed, if you have a PCI VGA board in your machine and both drivers
in your kernel, the ISA VGA driver may accidentally match the PCI board.
For now, the only solution to this is to not put both drivers in
the GENERIC kernels.

cgd e35cd5615f implement interrupt enable/disable and mapping as described in
the Digital Semiconductor AlphaPC 164 Motherboard Technical Reference
Manual.  This may not work, but it's the best i can do with the
documentation I have.
1996-11-17 02:30:25 +00:00
cgd ccc668e0d7 use the new common chained-interrupt support code. 1996-11-17 02:05:26 +00:00
cgd 6c9cb4aa9b compile cleanly with:
-Werror -Wall -Wstrict-prototypes -Wmissing-prototypes -Wcast-qual
1996-11-13 21:13:04 +00:00
cgd 8ffccdfae0 preliminary support for the EB164. The EB164 is more or less a 'normal'
21164 + 21172 box, with Yet Another Way of doing interrupts.  The
interrupt mapping and handling code hasn't been written yet, and none
of this code has been tested.  (Checkpoint of work in progress.)

cgd f8ab7cfbcd clean up some spacing in switch statements 1996-11-11 21:02:32 +00:00
cgd 1b03f1bca7 update for new bus.h macros. bus_io_* and bus_mem_* integrated into
single bus_space_* framework.  Unfortunately, bus_space_{read,write}_*
operations still imply barriers.  That will change soon.

cgd 2a73ef60b7 change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

cgd 2c47809239 include <sys/systm.h> for printf prototype 1996-08-27 16:28:08 +00:00
cgd 15f9c59baf check in the code used to build the kernel that Andrew Gallatin used to
figure out the correct IRQ for the ethernet on the AlphaStation 500.
That code is enabled via KN20AA_BOGUS_IRQ_FROB (but hopefully won't be
needed any time soon, and won't link w/o slight changes to other code).
Basically, when establishing an interrupt that we don't know what to
do with, prompt the user for what interrupt line to enable.  If you
get stray interrupts when you try to use the device (but not before),
then you've got the right line.

cgd 3c7eaa04e2 fix typo in comment 1996-08-19 04:19:01 +00:00
cgd b4bfcf063f 21040 ethernet chip on AlphaStation 500 lives in slot 6 (a slot not
found on the AlphaStation 600), and interrupts on interrupt line 13.
Thanks to Andrew Gallatin for booting a test kernel 32 times (trying
each interrupt line, looking for the right one) to find this.

cgd e295ad51df clean up stray interrupt handling a bit. 1996-08-15 22:17:44 +00:00
cgd b3703a8fcd oops; fix bogon in last. 1996-08-14 05:47:39 +00:00
cgd 1f675e847d say 'stray kn20aa irq' rather than 'stray PCI irq'; former is more correct. 1996-08-14 05:45:52 +00:00
cgd a96b24415d fix inadvertent reordering of switch which cases by slot number but
is ordered by interrupt number.
1996-08-14 05:44:31 +00:00
cgd 440a942944 fix bogus returns from dec_kn20aa_intr_map(), and slightly simplify interrupt
mapping code.  (instead of using a "slot" and multiplying by 4 and adding the
pin number later to get the IRQ, just use base IRQ value and add the pin
number.)
1996-08-07 04:33:21 +00:00
cgd efec732f4d fix a typo, add a function kn20aa_disable_intr() to disable a given
kn20aa interrupt line.
