mycroft 02905321b2 Foolish consistency. Mainly, always use underscores and sys/endian.h. 2000-03-16 15:09:34 +00:00
nisimura f7f5e0a24c Note that HX (PMAGB-B) has no support for small (less than 8 pixel width)
font.  If attempted, kernel will explode.

nisimura 220005d941 Eliminate unused sc_cookie field of struct ioasic_softc. 2000-03-15 03:07:44 +00:00
oster 1bad2e1909 Add the RAIDframe device major to the machine-dependent config files
so that the right entries get added to dev_name2blk[].  Needed for / on RAID.
(Whoops!  I missed checking these in when adding the RAID_AUTOCONFIG stuff.)
2000-03-14 15:56:51 +00:00
nisimura 8bf44847a8 Fix DEC3000/300 TC slot numbering. There is an address space hole
between two TC option cards and 3 builtin TC devices.  Was uncovered by
mrg's change made at Nov 1999 and pointed by tsutsui.
2000-03-14 05:53:33 +00:00
nisimura 6f5486c425 Switch to MI sfb (PMAGB-B) TC framebuffer driver which sports faster
text rendering assisted by SFB ASIC.
2000-03-14 05:34:04 +00:00
nisimura 8de02d3a76 - Comment out cfb (PMAG-B) 1024x768 framebuffer.
- Have Gallant19 font by default.

tsutsui d16c6f3272 Use DISKPART/DISKMINOR/DISKUNIT instead of dkpart/dkminor/dkunit. 2000-03-07 15:55:14 +00:00
thorpej a183d34f04 - Implement cnbell() -- ring the console bell. The cn_bell entrypoint
is optional.
- Add cn_bell to statically allocated consdevs as appropriate.
2000-03-06 21:36:05 +00:00
thorpej 23c5667cfe Use ANSI-style function declarations for the various inline functions

2000-03-05 18:46:14 +00:00
thorpej 7d57276982 Do partial lazy I-stream sync -- in the pmap_enter()/pmap_remove() cases
for now.  More to come.
2000-03-01 18:29:04 +00:00
thorpej 908f6bc4cd Infrastructure for lazy istream sync in the pmap module:
- Add a bitmask for the CPUs which need an isync before this pmap returns
  to userspace on that CPU.
- Define PMAP_USERRET(), a utility macro for userret() to use to process
  the deferred isync, and call it as appropriate in userret().
2000-03-01 02:22:03 +00:00
thorpej a192dc9c5b PMAP_ISACTIVE() now takes the cpu_id. This serves two purposes:
- Everywhere it was used, the cpu_id was already computed, so this
  saves computing it again.
- This will be needed for lazy istream sync.
2000-03-01 01:32:45 +00:00
thorpej 64911f1d2e Use cpu_number() here instead of alpha_pal_whami(). 2000-03-01 00:43:34 +00:00
thorpej fac7fc369f Put machine check info in cpu_info in the multiprocessor case, and
just have one statically allocate machine check info structure in the
single processor config case.

thorpej 0958e8149a x86-style PIO ops for USERLAND ONLY! Requires -lalpha. 2000-02-26 19:00:51 +00:00
thorpej df88882d80 - Add a bus space method for getting the translation for a window.
- Add sysarch methods for "get bus window count", "get bus window",
  and "pci conf read/write".

These are a hack, but they're what's necessary in order to make
XFree86 work in its current state.

mjacob 13e13336b2 Allow (re)setting of maxstrays after establishment of a shared interrupt.
This allows sporadic stray interrupt counts to be reset by an acknowledgement
of the same interrupt.

thorpej 52a2804a5c Add a new function call to the ISA DMA API: isa_dmamaxsize(), which returns
the maximum transfer size for the specified DMA channel.  Make all clients
of ISA DMA use this call to determine their maximum transfer size.
2000-02-07 22:07:27 +00:00
thorpej fe551f0e64 Fix a bug in disksort_*() which caused non-optimal ordering when multiple

thorpej 97eba73a40 If we have a Pyxis with the DMA page crossing bug, don't allow coalescing
of adjacent DMA segments.

XXX This is still not perfect... but making it perfect will probably
require additions to the bus_dma interface and the ISA autoconfiguration
interface.

veego 5b4e17169b Bring in the support to boot from ide drives. This is from dec_eb164.c.

2000-02-05 22:22:41 +00:00
veego 541c31000e Sync the ide support with dec_eb164.c rev 1.32:
Add the support to boot an ide slave drive and to boot from the secondary
ide channel.
Michael Hitch gave me the final hint how to do that and Havard Eidnes
tested it with his slave drive.
This should fix pr#8808 on the DS10.
Also remove one ideboot check which wasn't removed when I removed it from
dec_eb164.c.

mjacob d5e85e61cf Fixes PR#8836. Some changes made by somebody else were a tad incomplete so
configuring w/o SIO broke compilation. I forget why, but there was at one
point (and may still be) a dependency between SIO and EISA. This change
just makes things compile sensibly again. It may make no sense to build
a kernel w/o sio in this case. I can't test this conveniently because I
haven't got a 4100 with a video card in it at the moment.

thorpej 0aa48d5c55 New delay(), more carefully coded:
- Use explicit assembly; don't want the compiler optimizing things too
  much here.
- Subtract 2 for each iteration of the loop, rather than 3.  The loop
  consists of only 2 instructions (even the C version compiled to a
  loop of 2 instructions).

The latter change has squashed a fairly annoying timing bug in the
mii_bitbang module as used by the `ex' driver on my AlphaStation 500.

XXX delay() should maybe be rewritten again, to use the rpcc instruction.

thorpej 2a97466824 Rewrite the atomic locking primitives using in-line assembly. 1999-12-03 01:11:34 +00:00
thorpej d89260177d In pmap_page_protect(), don't reference a pmap we're unlocking via
the PV entry we just freed (D'OH!)
1999-12-02 23:40:27 +00:00
thorpej 9f7d189f05 Inline most of the remaining PALcode calls. 1999-12-02 22:08:04 +00:00
thorpej 90bc415584 Pull in the BWX inlines. We expect the arch to be set appropriately for
the assembler before these files are pulled in by the chip-sepecific files.
1999-12-02 19:44:49 +00:00
thorpej 4e08cc6996 CIA core logic with BWX enabled appears on EV6. We require at least
EV56 for the assembler to emit BWX opcodes, so set the arch to "ev6".
1999-12-02 19:43:58 +00:00
thorpej dc362cf369 CIA core logic with BWX enabled appears on both EV56 and PCA56. We
require at least EV56 for the assembler to emit BWX opcodes, so set
the arch to "ev56".
1999-12-02 19:43:25 +00:00
thorpej 0a2ea99c42 Inline the BWX instructions. 1999-12-02 19:41:39 +00:00
thorpej 4106b60175 Move atomic operations into <machine/atomic.h>, and make them in-line
assembly, rather than function calls.

...except alpha_atomic_testset_l(), which will go away completely once
I commit the new <machine/lock.h>.
1999-12-02 01:09:11 +00:00
thorpej c258dfae2f After reading the GCC `documentation' a little more, improve the inline
__asm() statements added previously for PALcode operations.
1999-12-01 18:23:11 +00:00
thorpej 12f7832ebc don't need private `imb' inline anymore. 1999-11-30 22:32:08 +00:00
thorpej 9314d7f4d7 Use ptoa() consistently when printing out how much memory we have, etc. 1999-11-30 19:31:56 +00:00
thorpej 69b252dfff Put some (disabled) debugging code into pmap_steal_memory(). 1999-11-30 18:18:02 +00:00
thorpej 89ae0bf93c Inline several things from pal.s:
- alpha_rpcc(), alpha_mb(), alpha_wmb() -- these are instructions, and
  we win by inlining them: rpcc is generally used for profiling, and
  the memory barriers really should execute as quickly as possible with
  minimal side-effects (like additional loads/stores required to call the
  functions!)
- alpha_pal_imb(), alpha_pal_rdps(), alpha_pal_swpipl(), alpha_pal_tbi(),
  alpha_pal_whami() -- these are PALcode ops.  We must specify some register
  clobbers for these.

We have a very decent size savings as a result.  My test system:
text    data    bss     dec     hex     filename
2671724 235848  377016  3284588 321e6c  /netbsd.bak
2617708 235736  377016  3230460 314afc  /netbsd

Most of this comes from fewer register saves/restores around spl*() calls
(now that alpha_pal_rdps() and alpha_pal_swpipl() are inlined).

Note that alpha_pal_rdps() and alpha_pal_swpipl() remain in pal.s to
maintain binary compatibility with LKMs that may use spl*() functions.

thorpej 871b54b6d2 Vector to a local function for the IMB IPI. 1999-11-30 00:26:55 +00:00
thorpej 18e6d486f4 Add an IPI which causes the target CPU to perform AST processing when
it returns to userspace.
1999-11-29 20:00:04 +00:00
thorpej 7f1ccd57ea Add a way to get/set a private pointer in the shared interrupt header. 1999-11-29 19:59:19 +00:00
thorpej df2cf70865 - Fix a botch in the IPI bitmasks (they were right-shifted by 1), and
add an IPI which causes the target CPU to perform AST processing when
  it returns to userspace.
- Add a way to get/set a private pointer in the shared interrupt header.
1999-11-29 19:58:39 +00:00
thorpej 68fb3dc662 Switch to the new pmap_remove() and nuke the old one. A simple fork/exit
benchmark shows at least a 10% improvement in the tearing down of a large
address space.
1999-11-29 18:37:28 +00:00
thorpej 94552ad5d6 - Use alpha_atomic_{add,sub}_q() to update the pmap statistics. We now no
longer need to lock the kernel pmap in pmap_kenter_pa() and pmap_kremove().
- Since locking the kernel pmap in interrupt context is no longer required,
  don't go to splimp() when locking the kernel pmap.
- Implement a new pmap_remove() function, not yet enabled by default.  It
  is structured like pmap_protect, and should be *much* faster.  This was
  actually written quite some time ago, but never committed because it
  didn't work properly.  Given the recent bugfix to pmap_protect(), "duh,
  of course it didn't work properly before...".  It seems to work fine now
  (have done several builds and run the UVM regression tests using the new
  code), but it is currently run-time optional so that some performance
  measurements can be easily run against the old and new code.

thorpej 1710fad449 Implement atomic addition and subtraction on quadwords. 1999-11-28 19:47:13 +00:00
mycroft 1d9d2c47c5 In pmap_emulate_reference(), always or in the bits. I know the code is trying
to be clever, but...
Also, a slight optimization for the write case.
1999-11-27 00:25:15 +00:00
mycroft f26df92bed Fix bugs in pmap_protect() that were responsible for the `ld.elf_so lossage'.
* We could overrun the eva by as much as L1SEG_SIZE-PAGE_SIZE.
* sva was advanced *twice* for each valid l3 or l2 page, causing it to get out
  of sync with the PTE pointers.

itojun e9a0023b37 bring in content of GENERIC.v6 into GENERIC.
remove GENERIC.v6 file (as it is part of GENERIC now).

"faith" interface is commented out by default as it is not really for
general use.
IPsec items are commented out as well, though we can enable "options IPSEC"
without export-related issue ("options IPSEC" will enable authentication
portion only).  We may need to think about it again.

if you have problem compiling with INET6 on archs I do not have access to,
please contact me.

XXX what to do with arch/arm32/SHARK{,.v6}?

mrg 9f1959ab2b split the "asc" and "tcds" searching into two separate sections and
keep a "tcdsdev" of the booted tcds device.  make sure that the "asc"
is the child of the tcds.  this fixes boot device detection on dec
5000/400 (prolly 400-900) machines in the presense of a tcds option
card, which would use the right tcds chip & disk scsiid of the last
attached tcds -- which meant it would choose the wrong disk, or not
find the boot device at all if the corresponding scsiid was unused in
the last attached disk.

XXX: this may need to be copied to dec_3000_300.c but i have no idea
as i can not test this hardware at all...

fixes PR#8771 by myself.

mjacob 8cf9a14802 Add in a step to actually probe for MCPCIAs. This allows us to run on
4100s that only have two of four possible MCPCIAs.
1999-11-16 18:37:24 +00:00
mjacob 2981278f40 Add in a define for a MCPCIA bridge register that would be suitable for
probing for with badaddr(9).
1999-11-16 18:36:27 +00:00
mjacob ce28c5e558 Make sure a MCPCIA exists before trying to initialize it. Also make
sure a MCPCIA softc exists before trying to do post-config cleanup
on it.
