thorpej f5cd6a7736 Add debugging support to the bus_space macros. If BUS_SPACE_DEBUG (or DEBUG) 
is defined, the bus_space macros will check to ensure that the bus address
and the target buffer (if applicable) are aligned properly for the size
of the type being used.  If they are not, a message will be displayed on
the console.

Strict alignment is required by the Alpha architecture, and a trap will
occur of unaligned access is performed.  These changes will aid debugging
of broken device drivers.

thorpej 528bbb95ed Add debugging support to the bus_space macros. If BUS_SPACE_DEBUG (or DEBUG) 
is defined, the bus_space macros will check to ensure that the bus address
and the target buffer (if applicable) are aligned properly for the size
of the type being used.  If they are not, a message will be displayed on
the console.

While strict alignment is not strictly necessary on the x86, ensuring
proper alignment can aid performance, and help make drivers more portable
to architectures (like the Alpha and StrongARM) which _do_ require strict
alignment.

thorpej 14df007174 Oops, don't forget to fill in *addrp. 1998-06-07 00:29:29 +00:00
thorpej 0890af5ca8 Only disable an interrupt line after MAXSTRAYs if there is no handler 
attached; we get stray interrupts on PCI devices sometimes, for some
unknown reason.  (Similar problem exists on the 164SX, which also has
a Pyxis.)
 1998-06-06 23:29:23 +00:00
thorpej 331a7f56c1 Remove some debugging code no longer relevant now that we have DMA 
window chaining.
 1998-06-06 23:11:52 +00:00

thorpej 7a6d646c9b Implement bus_space_{alloc,free}() for BWX bus space. 1998-06-06 22:28:16 +00:00
thorpej 30f9be231f Restructure cpu_reboot() a bit, and add support for powering down 
on the Sun4m if RB_POWERDOWN is specified.
 1998-06-06 21:46:51 +00:00
thorpej 1c6a275e9c Only attempt the powerdown if the power register was mapped. 1998-06-06 21:40:20 +00:00
thorpej 402c48737f needs-flag'ize the power device. 1998-06-06 21:30:34 +00:00
thorpej 9553573381 If we have APM, only power down if RB_POWERDOWN was specified (fall into 
RB_HALT case if it fails).
 1998-06-06 21:27:31 +00:00
thorpej fe17c44d6c Add support for software powerdown of the Digital Personal Workstation. 1998-06-06 20:53:41 +00:00
thorpej 04ba8480ae Use REGVAL64() to frob the Pyxis interrupt mask register. 1998-06-06 20:42:36 +00:00
thorpej 098dd211c7 Define a REGVAL64() for some Pyxis registers. 1998-06-06 20:40:14 +00:00
thorpej 49aea111fb If the platform specified a powerdown hook, and howto has RB_POWERDOWN, 
call the hook.  If the hook fails, print a warning, and just halt (RB_HALT
is implied by RB_POWERDOWN).
 1998-06-06 20:39:04 +00:00
thorpej 1733ad8dc5 Clean up a little, and add a `powerdown' hook in the platform structure. 1998-06-06 20:18:50 +00:00
thorpej d08070a693 Add a comment describing the locking needs of the alpha_sgmap. 1998-06-06 20:12:28 +00:00
augustss db50fa53b8 Add Aria driver. 1998-06-06 10:14:21 +00:00
mrg e666cd4b3b install floppy kernel 1998-06-06 05:36:53 +00:00
mrg ff6c535817 sync with other md_root.c files. 1998-06-06 05:12:54 +00:00
mrg 4bc09321a9 add md to the "sparc_nam2nlk" and "chr2blk" arrays. the former fixes 
panics seen on a floppy boot in setroot() as it could not properly
determine the root device.
 1998-06-06 05:03:23 +00:00
thorpej 85d08836f1 - Don't call *_dma_init() twice; there's no need to. Just do it in *attach(). 
- Display Pyxis revision properly.
 1998-06-06 01:33:44 +00:00
thorpej c0fa3c6ac4 Don't call *_dma_init() twice; there's no need to. Just do it in *attach(). 1998-06-06 01:33:23 +00:00
thorpej 59d76407b4 Display information about which sgmap we're attempting to initialize 
if we die in alpha_sgmap_init().
 1998-06-06 01:31:46 +00:00
ragge 08079a8f21 Don't compile in any rasterconsole code. 1998-06-05 22:17:02 +00:00
ragge 88d55c928c Add virtual console support. 1998-06-05 22:02:56 +00:00
thorpej 9331237596 Oops, turn off some debugging printfs. 1998-06-05 21:47:14 +00:00
thorpej bf8523f4e4 - Egads! There are Pyxis "Pass 1" chips that do not have the DMA bug! 
Use the check recommended by the Digital Workstation engineers; look
  for Miata 1 systems (i.e. with Intel SIO).  From Andrew Gallatin.
- Update copyright (Pyxis and BWX).
 1998-06-05 19:25:19 +00:00
thorpej f251e3372d Don't attempt to map the PCI IDE interrupt at bus 0 device 11 on the 
AlphaPC 164 and AlphaPC 164LX - these are wired to compatibility mode.
 1998-06-05 19:15:41 +00:00
thorpej 1aa688234e Miata 1 has an Intel SIO at bus 0 device 7 and a CMD PCI IDE at bus 0 
device 4.  Miata 1.5 and Miata 2 have a Cypress at device 7 and PCI IDE
at functions 1 and 2 of the Cypress (like the PC164SX).  These on-board
PCI IDE controllers are wired to compatibility mode, so don't bother
trying to map the interrupt.
 1998-06-05 19:04:51 +00:00
thorpej a1c151d56b Add system variation for Miata 1.5. 1998-06-05 18:18:37 +00:00
thorpej c072110af0 Actually, I did use a few of them on this file (I wasn't clear enough 
in my mail to Ross, I guess...)
 1998-06-05 17:42:53 +00:00
thorpej bb362059ac On Pass 1 Pyxis, disable PCI Read Prefetching, and warn the user about 
the DMA bug that exists on this Pyxis revision.
 1998-06-05 17:24:11 +00:00
thorpej 29977868a7 What was called CNFG in ALCOR and ALCOR2 is actually called PYXIS_CTRL1 
in Pyxis.  Add a comment to this fact.
 1998-06-05 17:22:34 +00:00
thorpej 73e5032ac9 Define the Pyxis-specific bits in the CIA_CSR_REV register (ID mask, and 
the ID for the 21174).
 1998-06-05 17:16:31 +00:00
thorpej 2701ea3ef3 Add DEC_550 (Miata). 1998-06-05 17:03:07 +00:00
ross 5790ee09ee Revert...Jason didn't use Andrew's diffs. 1998-06-05 15:28:40 +00:00
