thorpej f948e430bb Provide a hook for bypassing space accounting, needed to support ISA PnP
for now.
1998-07-31 04:37:02 +00:00
thorpej eb32016a95 Split up using BWX for PCI config and bus access. Default to using BWX for
the former, but not the latter.  Hopefully, this will address some problems
people have been experiencing w/ some devices on Pyxis systems when BWX
is used for bus access.  (If it's not used for PCI config access, we can
get fatal machine checks while probing behind PCI-PCI bridges!!)

mycroft da2e61d160 Delint. 1998-07-27 13:55:32 +00:00
thorpej b0b64545e8 Add cs* at isa? port 0x300, wildcard IRQ and memory address, to pull
them from the EEPROM.  Wildcard DRQ to force memory-mode operation; this
value is not available in the EEPROM and must be configured manually.
1998-07-27 01:57:56 +00:00
thorpej 2385ee5eca Provide PMAP_{,UN}MAP_POOLPAGE(). 1998-07-24 20:32:07 +00:00
is 6054d626f9 Switching dev/ic/lpt.c to use spllpt() instead of spltty(). It doesn't use
tty structures, and on some machines (namely the DraCo internal lpt, and some
multi-i/o boards for Amigas and DraCos), tying spltty to the pretty high printer
interupt level would hurt serial performance.

On all affected ports but Amiga, spllpt() has been defined in machine/intr.h
to be spltty(), thus preserving old behaviour. Portmasters are encouraged to
change is, if they feel something else is better (e.g., one of its own were
possible).

ross d58ad29b6c Kill the old extern mchkinfo pointer and prototype cpu_mchkinfo().
This file has been collecting prototypes and other things used in the MD
code...that's bad...because this is exported to the MI kernel.
1998-07-13 19:10:14 +00:00
ross 48257ecec1 Define cpu_mchkinfo() to locate the mchkinfo struct. This is used to fix
the recent bug where Multias around the world have been aborting back to
SRM with no message at all as they tried to attach a TGA or VGA console,
because the old mchkinfo pointer wasn't allocated prior to use.

And contrary to widespread rumour, this bug has nothing to do with my
LCA IDE mod...that worked just fine. "Not guilty."
1998-07-13 19:07:33 +00:00

someone else to figure out the best machine independent fashion of
fixing ptoa to handle > 32 bits.

mjacob 434b3fe82b tentative better fix for allocating the correct number of mchkinfo structs 1998-07-08 16:28:25 +00:00
mjacob ff376fbd03 Doh! Jason caught me being really stupid. There isn't necessarily
a linear 0..N mapping out of alpha_cpu_whami - which is what I was
using to index the new cpu machine check array. This is a quick hack
back to just using the first element while I think of a kinder function
that will do the function (per-platform) of whami->VIRTUAL CPU ID, which
if you think about it, is really necessary anyway.

mjacob 638f0aab7c Clarify comment about what nodes are being 'found' and noted for later
use by an error handler:

 * There can be only one TurboLaser, and we'll overload it
 * with a bitmap of found turbo laser nodes. Note that
 * these are just the actual hard TL node IDS that we
 * discover here, not the virtual IDs that get assigned
 * to CPUs. During TLSB specific error handling we
 * only need to know which actual TLSB slots have boards
 * in them (irrespective of how many CPUs they have).

mjacob adf058f0f7 There can only be one TurboLaser node, and now we'll overload
into the integer tlsb_found a bit map of found nodes and export
it to the rest of the kernel. This is so that at machine check
time when we're doing some TLSB/KFTXX error handling we don't
have to attempt a badaddr to look at all TLSB nodes (which will
just be too sad to try...).

mjacob 6f87cdce00 Start of the platform specific (RAWHIDE) machine check handler. This
is not really needed for this platform, except that we might want to
handle PCI errors which get reported through here. In any case, this
prints out more info than is usual. Will probably need to detune
this to be based upon DIAGNOSTIC defines.

ross a0f70c580c New platforms: Mikasa and Mikasa/Pinnacle, aka Pinkasa.
Like the 1000A, the AlphaServer 1000 has a daughtercard assembly that
integrates the CPU and core logic, so these can be ev4/apecs or ev5/cia.
New systype, and, sigh, another way of doing interrupts and another
mystery icu.

thorpej 78d7f07efd Very preliminary support for the Tadpole/DEC AlphaBook. These are basically
AXPpci33 machines + power management and a Cirrus PCI-PCMCIA controller.

There is currently no support for the power management facilities, and
the PCI-PCMCIA controller driver needs some work, but this should boot

the iot, memt, and pc in the call so that pci_1000a_pickintr() (and the
other routines in that module) do not need to be aware of the core logic

ross 92aafa4a46 Identify ST_DEC_1000A as PCI/EISA.
New macros:

	LOCATE_PCS(struct rpb *hwrpb, int cpu_number)
	PCS_PROC_MAJORTYPE(struct pcs *)
	PCS_PROC_MINORTYPE(struct pcs *)

Define LOCATE_PCS() to map (hwrpb, cpu_number) -> Per-Cpu-Slot structure.

address on 2 architectures anyhow.  Also, move the definition of the `label_t'
type inside _KERNEL protection, since it is specific to the in-kernel
setjmp()/longjmp() implementations.
1998-06-14 20:09:22 +00:00
cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

thorpej 53394a1d41 Change the ISA DMA API to take an isa_chipset_tag_t rather than
a struct device * corresponding to the ISA bus device.  The ISA DMA
controller driver functions have been renamed and now take a struct
isa_dma_state *, and are called indirectly by machine-dependent code
which provides the DMA state.

These changes allow e.g. `ofisa' (the OpenFirmware configuration
mechanism for the ISA bus, used by e.g. Sharks) to use the MI ISA
DMA controller code.

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 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
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 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...)

thorpej 29977868a7 What was called CNFG in ALCOR and ALCOR2 is actually called PYXIS_CTRL1
in Pyxis.  Add a comment to this fact.

ross 8f455480ef Tweak the copyrights a little bit. pci_550.h gets a TNF copyright, not
CMU, and pci_550.c keeps TNF but gets "Andrew Gallatin and Jason R. Thorpe".
1998-06-05 03:34:27 +00:00

thorpej 3249813e11 For whatever reason, the firmware seems to enable PCI loopback mode if it
also enables BWX.  Make sure it's enabled if we have an old, buggy firmware
rev.
1998-06-04 22:58:33 +00:00
thorpej d4d49905dd Add support for using BWX for PCI config space and PCI i/o and mem space
on the ALCOR2 and Pyxis.  BWX is enabled iff:
- It hasn't been disabled by the user (patch `cia_use_bwx' or build cia.o
  with the option "CIA_USE_BWX=0"),
- it's enabled in CIA_CSR_CNFG,
- we are running on an EV5-family processor,
- BWX is in the processor's capabilities mask.
1998-06-04 21:34:45 +00:00
thorpej 616125f8d1 Deal with a hardware bug in Pass 1 and Pass 2 Pyxis chips. Basically,
the scatter/gather TLB cannot be invalidated on these chips.  So, to
work around this, we configure the otherwise unsed DMA Window 2 as a
2M SGMAP window at 128M, point all of its page table entries at the
DMA spill page, and, when the TLB is to be invalidated, put the PCI bus
into loopback mode, and create a target hit on Window 2 every 64k for
the number of TLB entries (plus a few ... it seems to not work unless
we read a few extra times), forcing out old TLB entries to make room for
the new, dummy target hits.
1998-06-04 18:11:23 +00:00
thorpej a51d42503c Export the spill page PTE, and provide a hook to initialize it early. 1998-06-04 01:22:52 +00:00
thorpej 6dc28f5445 CIA and Pyxis have 8 scatter/gather TLB entries. 1998-06-04 01:18:22 +00:00
thorpej 32fef69ef7 Define the CIA control register. 1998-06-04 01:04:11 +00:00
thorpej d94f02f9fd Ok, now we _REALLY_ have Pyxis recognition correct. There are two systypes
that can have Pyxis: EB164 (AlphaPC164LX and AlphaPC164SX) and DEC_550 (Miata),
and these systypes/variations _always_ have Pyxis.
1998-06-03 23:16:55 +00:00

thorpej d6041754c2 Allow the DMA tag to specify a boundary contraint. If the device has a
more strict boundary, the map will use it, otherwise the map will inherit
the tag's, unless the tag's constraint is 0 (no boundary constraint).

thorpej 1ef3ca572e - Additional rearrangement for the sake of running on the DECstation some
day.
- Convert to use bus_dma.
- Fix cleaning up unaligned start address.
- Correctly determine if the device supports Fast SCSI, and adjust the
  minimum sync period accordingly.
- Compute minimum sync period correctly on the 25MHz devices.
- Use GPI2 to determine if we're a 25MHz or 40MHz device.
- Currectly determine SCSI ID and "fast mode enabled" for the built-in
  TCDS on DEC 3000 models, using cached information from the PROM environment.
1998-05-26 23:43:05 +00:00
thorpej ab087002d1 Make this into a proper attachment (i.e. use asc_tcds) and clean up

1998-05-26 23:37:44 +00:00
thorpej 3aa84f9e26 - Make this into a proper attachment (i.e. use asc_tcds) and clean up
the namespace accordingly.
- Set FCLK in the CFG3 register if we have a > 25MHz clock.
- Indicate that we support Fast mode to the back-end if we're told we're
  fast by the TCDS layer.
- Correctly compute the minimum sync period.
1998-05-26 23:37:27 +00:00
thorpej 3ce836df8d Make the TCDS attachment of the ASC driver a proper attachment (i.e.

1998-05-25 20:59:01 +00:00
thorpej e569598438 On DEC 3000s, ask the prom for the SCSI ID and "fast mode enabled" of
the built-in TCDS, while we can still access the prom.
1998-05-25 05:16:42 +00:00
thorpej 085b73d2db Add "SCSIID" and "SCSIFAST" environment variables present on the
DEC 3000 systems.
1998-05-25 04:01:10 +00:00
thorpej 57c68363d6 Add support for reading the SCSI ID and "fast mode enabled" from the
PMAZB-AA and PMAZC-AA EEPROM.
1998-05-25 01:14:38 +00:00
thorpej 3b9e9634fb - Change the tcds child locator from "slot" to "chip", making it look less
like a TurboChannel locator, and more like what is actually going on.
- Allow tcds and asc children of tcds to be cloned.
1998-05-24 23:45:29 +00:00
thorpej d3ead78027 Several changes to the TurboChannel Dual SCSI driver:
- Fix the autoconfiguration model; the TCDS children don't attach to
  TurboChannel, so don't make it look like they do.
- Make the driver use bus_space (not bus_dma yet; soon)
- Recognize the PMAZ-FS (baseboard fast SCSI on DEC 3000s) and the
  PMAZB-AA (TCDS option card) and PMAZC-AA (TCDS fast SCSI option card).
- Rearrange it a bit, so that it can eventually be made into an "MI"
  TurboChannel driver (i.e. work on DECstations).

thorpej 3dfd62c76f cs_heldchar is gone. 1998-05-23 00:51:10 +00:00
thorpej 0cb3acc9ae Correct a small, but fatal, typo. 1998-05-21 23:38:04 +00:00
thorpej 93d96b3415 Add LOCKDEBUG (commented out). 1998-05-20 18:09:16 +00:00
thorpej a2f214a443 Add fine-grained locking, using a locking protocol modeled after the i386
UVM pmap's locking protocol, written by Chuck Cranor.  Not all of the
support for multiple processors is here yet, but the kernel does run
under moderate loads with LOCKDEBUG (all locking operations are no-ops
unless LOCKDEBUG is turned on).

This is by no means complete... there are still some possible snares
to take a look at.
1998-05-20 04:05:50 +00:00
thorpej 6626878e7b It is no longer necessary for pmap_pinit() and pmap_release() to be
pmap interface functions, as NetBSD no longer uses statically allocated
pmaps (except for the kernel pmap, which is special-cased anyhow).
1998-05-19 19:00:11 +00:00

1998-05-19 05:21:34 +00:00
thorpej dc13176aec No need to keep global pointers to the initial kernel level 2 and level 3
page tables.  Also, rename Lev1map to kernel_lev1map.

1998-05-14 21:53:40 +00:00
drochner 95bdb660ed Simple screen attribute handling for wscons.
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.
1998-05-14 20:49:55 +00:00
thorpej d19fbe1196 Garbage-collect the old confargs stuff that was used in the Early Days.

SGMAPs if a direct-mapped window fails.
1998-05-13 21:21:16 +00:00

thorpej 0624060713 Rework PCI interrupt mapping on the EB164 systype. Rather than computing
interrupt routing directly, use the interrupt routing information provided
in the PCI "line" register.  The previous scheme did not work properly on
AlphaPC 164SXs.  Also, be silent about the fact that 0/8/x does not
have its interrupt mapped; this is to be expected on the 164SX (this is
the Cypress PCI-ISA bridge, which has IDE wired to compat mode on functions
1 and 2; the 164SX does _not_ have PCI IDE on device 11 like other AlphaPCs).

thorpej 861c7a7e2d Add a stub pckbc_machdep_cnattach() which simply returns an error. This
function is meant to glue the new pckbd driver to the old console code
on ports which use the old PC-style console code.  This will eventually
be purged when all of the old legacy consoles have gone away.

	CIA revision > 2 -> 21174
1998-04-28 18:11:35 +00:00
thorpej b217194508 Fix the semantics (and the comment describing them) of pmap_update(). This
function is intended to process any deferred pmap operations, and is not
meant as a general means of flushing the TLB.  Since this pmap module does
not defer any operations, make pmap_update() do nothing.
1998-04-27 19:17:16 +00:00
thorpej 30188853dc Increase the efficiency of pmap_l{2,3}pte() somewhat, by allowing the
caller to pass an optional 3rd argument, which is the previous level
PTE corresponding the virtual address.  If this argument is non-NULL,
the table walk otherwise necessary will be bypassed.

thorpej 164f56220e Add support for the Cypress CY82C693 PCI-ISA bridge. This bridge is more or
less like an Intel SIO except that the ELCR registers are accessed differently
than on the Intel SIO.

XXX This code needs to be split up into bridge front-end and PIC back-end
XXX pieces.
1998-04-14 22:31:17 +00:00
thorpej 4c01c3c48e Pass the pci_chipset_tag_t to sio_intr_setup(). XXX This code should be

devices can share code.
1998-04-14 22:20:59 +00:00
tv b21bfbde11 Add -Wno-main conditional on compiler being gcc 2.8 or egcs. (This adds
a HAVE_GCC28 check-variable that can now be used to add other gcc-2.8
flags in cases where they may be useful, or to remove gcc 2.7.2 "bug
workaround" flags.)
1998-04-12 23:47:41 +00:00
mjacob e40e2ff2d0 A little buglet: softc for pceb is same as sio- so declare it as such.
By not doing so, a very obscure bug followed where the config search

two Qlogic ISP cards that followed.

thorpej a95651eaea Add a PMAP_KERNEL_PTE() macro that returns the PTE for a given KVA. If
DEBUG, this performs a table walk.  Othwise, the Virtual Page Table is
used.  Use this macro in a few places where this was done by-hand.

Make vtophys() use PMAP_KERNEL_PTE().  In non-DEBUG cases, this is
a fair bit faster.
1998-03-27 19:18:04 +00:00
ross 2ce8cda3e5 Get rid of a /* in a comment. 1998-03-27 01:17:18 +00:00
thorpej b1e15c2005 Add some robustness to pmap_alloc_physpage(): Instead of panic'ing if
we can't get a page, find an inactive pmap and pmap_collect() it,
freeing up a few pages.  Go ahead and die if we can't allocate a page
after 5 tries.
1998-03-27 00:52:43 +00:00
thorpej b86884a71a Give pmap_collect() some substance: when called, a process is being
swapped out, so remove all of the physical mappings the process has
in order to free up the page table pages.

Since the pmap module is allowed to "forget" mappings, pmap_collect()
may be called in other situations where the memory situation is desperate,
although it's more likely that the pages will simply be needed again the
next time a process runs.
1998-03-26 22:18:36 +00:00
thorpej 531db9e0d3 Sanity check the virtual addresses in the kernel and non-kernel cases
of pmap_enter() (and pmap_kenter_*()).  Remove diagnostic check for

incorrect, nonetheless.

1998-03-24 05:15:07 +00:00
thorpej a26a53fbbc Slight hack to allow the MI SCC driver to be used at cdev major 15
for testing purposes.  Normal kernels still get the Alpha-specific
SCC driver.
1998-03-24 05:13:59 +00:00
thorpej ee83014c4d Initial mostly-working ioasic attachment for the MI 8530 SCC driver. It is
enough to use as a console on my DEC 3000/400 (connected to a VT-520
terminal).

XXX The MI SCC driver needs serious changes to handle platforms which
have muliple SCC attachments (e.g. the Alpha port, which has an ioasic
attachment for TurboChannel systems and a gbus attachment for TurboLaser
systems).

XXX The MI SCC driver also needs changes to deal with the wacky (to put
it mildly) way the chips are wired up on the ioasic (on both TC Alphas
and DECstations).  These are going to come along later.
1998-03-24 05:12:00 +00:00
mjacob 4ccb969d0b Okay, handle the ALLOCNOW case by doing the appropriate adjustments

mjacob 66194d05bc Do a more complete job of figuring out what kind of DWLP? we have- figure
out how much s/g ram is available. Can't really use the 128K entry S/G
ram yet- but I'll fix that later. More importantly, add in a dwlpx_iointr
handler that will try and figure out what the DWLPX error is and at
least print out what is happening- I actually found it useful in S/G
entry debugging as it could tell me that I had some bad S/G entries.

  change commented-out /* && cn_tab.cn_screen */ to && raster_console()
  * Add DDB hooks.
  * Note where Alpha console ignores carrier on consoles.
  * Add pmax-derived console tty-size code inside HAVE_RCONS
  * Fold in gross pmax rcons-input hooks, inside HAVE_RCONS

thorpej a5260cbda0 Use atomic set/clear bits in pmap_activate()/pmap_deactivate(). 1998-03-22 07:27:54 +00:00
thorpej fcfe2f1539 Implement a set of `atomic' (using load-locked and store-conditional)
operations.  Initial set includes:

alpha_atomic_setbits_q()	set bits in a quad

1998-03-22 07:26:32 +00:00
thorpej 9db8ae93c8 - The pmap now includes support for ASNs. We no longer need to flush
the TLB and I-cache in the SWITCH_CONTEXT macro.
- Right after switching to proc0's newly-created context at startup time,
  flush the TLB and I-cache; this is the only place where it's not done
  automatically.
- Fix a nasty bug in a critical section of cpu_switch(); change the
  pmap_activate -> SWITCH_CONTEXT -> pmap_deactivate sequence to
  pmap_deactivate -> pmap_activate -> SWITCH_CONTEXT.  This prevents
  erroneously marking a pmap inactive if switching to a process that
  shares it's address space (and thus its pmap) with the oldproc!  Noticed
  by Chris Demetriou.
1998-03-22 05:46:02 +00:00
thorpej c0cc1ed476 Implement support for Address Space Numbers, greatly reducing the number
of TLB and I-cache flushes, significantly speeding up context switches.

Once again, many thanks to Chris Demetriou and Ross Harvey for code
review and debugging assistance!

1998-03-19 06:44:25 +00:00
thorpej 003c50d1d5 Add a macro to invalidate the TLB for a given pmap/va pair. TLB
invalidation algorithm:

	if (old mapping had PG_ASM set || pmap is active) {
		TIBS(va);
		if (also sync I-stream)
			imb();
	}

The check for "old mapping had PG_ASM" will get all kernel mappings (since
kernel mappings always have PG_ASM set).

This allows us to remove the bogus check for the kernel pmap in
active_pmap() - do so.

Use the new TLB invalidation macro whenever such action is needed.
1998-03-18 23:55:25 +00:00
thorpej 15adb17803 Eliminate the last argument from pmap_remove_mapping(); it makes its own
decisions about TLB invalidation.
1998-03-18 23:11:44 +00:00
thorpej 7ee4af11a7 Change active_pmap() to use the CPU mask (XXX and check for kernel pmap

thorpej 605472f676 Optimize out a TLB invalidation in a common case of pmap_enter(): if
the PTE was previously invalid, no TLB invalidation is necessary because:

	(1) when a PTE is invalidated, its entry is flushed from the
	    TLB

	(2) the PALcode won't install an invalid PTE into the TLB.
1998-03-18 22:13:58 +00:00
thorpej cfdf9a95ad Keep track of which CPUs are using a pmap by setting/clearing bits
in the pmap's CPU mask in pmap_activate()/pmap_deactivate().
1998-03-18 21:57:03 +00:00
thorpej 43614761e3 In cpu_exit() deactivate the address space before freeing the vmspace
structure.  We will continue to run on this context (which is the
global Lev1map at this point) right up until we switch to proc0's
context in switch_exit().
1998-03-18 20:38:07 +00:00
thorpej 87eb2cfded Don't call pmap_deactivate() if we jumped into the middle of cpu_switch()
from switch_exit(), since by this time, the vmspace will have already
been deactivated and freed.
1998-03-18 20:36:13 +00:00

1998-03-17 04:53:43 +00:00
thorpej 00452b441f Move PTE-related constants here, and make them not depend on a hard-coded
page size (i.e. use the one initialized from the HWRPB at boot time).

Do a bit of cleanup while here, rendering old inherited constants obsolete.
1998-03-12 07:29:21 +00:00
thorpej 4d8723232d Garbage-collect a bunch of constants that were inherited, but are no

thorpej dfe0937a7e If not DEBUG, use the Virtual Page Table to get the PTE for kernel mappings
in pmap_enter() and pmap_emulate_reference().
1998-03-12 02:59:22 +00:00
thorpej 30766180a3 Nuke these; they are long-since obsolete. 1998-03-12 01:28:01 +00:00
thorpej 152a4bfa60 Increase the maximum userspace address to 4TB. Leave the stack at 8G
for now, but make a note that we might want to move it down to 4G later.
1998-03-12 01:25:52 +00:00
thorpej e046925c3a Massive cleanup and partial rewrite of the NetBSD/alpha pmap module.
Major change is that page table page management has been completely
rewritten.  Page tables are now accessed via K0SEG (no more KVA space
wasted on user page tables), and a much larger user address space is
supported.

Many thanks to Chris Demetriou and Ross Harvey for helpful insight and
debugging assistance.
1998-03-12 01:24:52 +00:00
thorpej 900e1c90bd Nuke ALPHA_STSIZE and ALPHA_MAX_PTSIZE. Add macros to compute and operate

thorpej a2db880e8c In kcopy(), make sure we save and restore the old fault handler; kcopy()
is called from uiomove(), which may be in the code path of servicing

1998-03-02 00:49:01 +00:00

ross 39254d4d4b Poll console at 50 Hz, not 1024 Hz! (4 tlb and imb coherency ops per poll
make this exceedingly expensive even on an alpha)  Note: only 3 systypes
still use promcons.

ross 2170c2a46d Force elf symbol sections to an addressable boundary. 1998-02-28 10:38:55 +00:00
cgd 18a1481f7a Use NFS_BOOT_DHCP rather than NFS_BOOT_BOOTP. The former is more
flexible, and the boot blocks use DHCP already(!!!) and it'd be good
for the kernel to be consistent with them.
1998-02-28 02:01:32 +00:00
thorpej ba3ddd48ad Move the code that enters and removes entries from the pv_table into

1998-02-28 01:07:05 +00:00
thorpej 9bbe89ea3f Garbage-collect the kpt_page stuff; it was basically unused in this
pmap, and isn't applicable to how dynamically allocated kernel page
tables will work on the Alpha.
1998-02-27 22:25:25 +00:00
thorpej faf1155de5 Revamp pv_table management:
- Make pv_table an array of struct pv_head's, which contain LIST_HEADs
  for the pv_entry's, as well as page attributes (mod, ref, ptpage).
- Use <sys/queue.h> to manipulate pv_entry lists.
- Fix several obvious bugs in pmap_collect_pv().
- Use K0SEG to access pv_page's.
1998-02-27 19:39:03 +00:00
thorpej f17bbcfffa Changes necessitated by the fact that all pmaps have their own level 1
page tables: use curpcb to determine which level 1 map defines the
current VM context, and use that level 1 map when mapping and unmapping
the PROM.
1998-02-27 04:03:00 +00:00
thorpej c4e7c88520 Step 1 of the Grand Alpha Pmap Rototill:
- Clean up pmap_bootstrap() some, and make a slight change to how the
  PROM mappings are saved.
- Give each pmap its own level 1 page table, rather than sharing a global
  level 1 page table.  This will eventually allow for Very Large user
  address spaces.
- Keep a list of all pmaps, so that when kernel level 2 page tables are
  allocated, all level 1 tables may be updated.
- Add a couple of functions for allocating and freeing page table pages.
- Add a few comments about ASN allocation.
1998-02-27 03:59:58 +00:00
thorpej 5d56ce57ba Several changes related to all pmaps having their own level 1
page table:
- Update the current hwpcb pointer in the SWITCH_CONTEXT macro, so that
  we know it's always correct.
- Optimize cpu_switch(): if we're switching to ourselves, skip the
  actual context swap.
- Clean up some comments and remove some code rendered obsolete by
  the fact that address spaces are now selected by switching to a
  new level 1 page table.
1998-02-27 03:53:49 +00:00

thorpej 8354e68508 Remove "class" declarations, and add "devclass" declarations where
appropriate.  Fix several inconsistencies between device class and

1998-02-16 22:12:45 +00:00
thorpej b4e77b173a Add support for non-contiguous physical memory, using MACHINE_NEW_NONCONTIG.
These changes also recover memory that is located before the kernel in

for console I/O.  Written by Chris Demetriou and myself.
1998-02-16 03:59:55 +00:00
cgd 1584dc4420 The pmap_emulate_reference warning about the page not being managed should

Also, make model name closer to what driver prints startup.
1998-02-13 04:33:30 +00:00
cgd 25d056473c Clean up kernel initialization. Use the bootinfo structure (or innate
knowledge) earlier, and gather all information needed earlier.  Mark the
init code carefully re: when it can print stuff out, when it can expect
the firmware to stop working, etc.  Be more careful about using the PROM
console and other PROM facilities, and hint that in the future all use
of firmware/boot program callbacks by the kernel should go away (since
the world may not be mapped the way the firmware/boot program wants!).
1998-02-13 02:09:03 +00:00

thorpej bd60d9c62d Rewrite the way the platform model string is determined:
- Attempt to find the model string in the HWRPB's DSR area.  Failing that
  (if the HWRPB version is too old)...
- Look up the system variation in a variation/string table.  Failing that
  (unknown variation)...
- Create a default model string using the variation number.

(filling them in if the boot blocks didn't pass them), and make versioning
a small bit more sane.

optimal (really should be done further down the food chain), but we
can't really do that in a nice way right now, and this is much better
than what we had before (which was to steal memory pages before the
VM system was bootstrapped).

thorpej e62d894d7a Implement a prefetch spill page for SGMAP DMA. This works around a slight
annoyance on systems that prefetch the next page during memory -> device
DMA if the DMA comes within a certain distance of the end of the current
page.  This could cause machine checks since the PTE after the last page
would not have the valid bit set.

(I'm not going to complain about this slight kludge too much, since prefetch
makes DMA much faster...)

thorpej 4730a8cbec Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>:
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
  supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
  by the way it's used).

The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.)  The __indr_reference
change was made for consistency.
