dbj 1ddcb8ee87 added a couple of functions missed when chuq removed PMAP_NEW 1999-09-21 11:03:53 +00:00
thorpej 11cae42531 Centralize the declaration and clearing of `cold'. 1999-09-17 19:59:35 +00:00
chs b9604a3f30 make this compile again after PMAP_NEW cleanup. 1999-09-16 14:52:06 +00:00
thorpej 3b01d1b872 Rename the machine-dependent autoconfiguration entry point `cpu_configure()',
and rename config_init() to configure() and call cpu_configure() from there.
1999-09-15 18:10:33 +00:00
chs f3a668ed84 eliminate the PMAP_NEW option by making it required for all ports.
ports which previously had no support for PMAP_NEW now implement
the pmap_k* interfaces as wrappers around the non-k versions.

mycroft c3e1f6741d A foolish consistency. 1999-08-30 18:58:01 +00:00
dbj 45ec8742b1 minor rework of dma driver
now uses the DMACSR_READ bit and no longer keeps _nd_dmadir in softc
unified transfer cleanup code, now in routine next_dma_finish_xfer()
fixed bounds checking on registers after transfer.
removed checking for bus errors since the bit is always set on some nexts
(specifically, on mourning, a 25mhz 68040 mono slab)
fixed a couple of dma bugs involving chaining dma buffers.
1999-08-29 05:56:26 +00:00
dbj ec9b8358dc made debugging printfs switchable at run time via the "xe_debug" variable. 1999-08-29 05:51:45 +00:00
dbj a47891200f fixed DMACSR_BITS definition to reflect DMACSR_READ bit renaming 1999-08-28 09:42:44 +00:00
dbj 3c215084bc discovered the purpose of another bit in the dma control register.
DMACSR_READ is now a CSR status bit which can be used to know if current transfer is
from cpu to device.
the old DMACSR_READ bit is renamed DMACSR_SETREAD.  This is a control bit that tells
the dma transfer to be from cpu to device.

thorpej 2cf3330a1b Garbage-collect reference to <sys/dmap.h>. 1999-08-23 22:29:37 +00:00
simonb 06a92524c2 Include <sys/bswap.h> for function prototypes. i386, pc532 and vax
still include <machine/byte_swap.h> and define macros for some of
the bswap*() functions.

dbj 383544139f remove some debugging hacks that were no longer being used. 1999-08-17 05:09:13 +00:00
dbj ab21be8e3c implement _bus_dmamap_load_raw_direct 1999-08-17 05:07:59 +00:00
thorpej 28fb7c1eb8 Define cpu_number() as discussed on tech-smp. 1999-08-10 21:08:05 +00:00
thorpej eb20bbc780 Change the semantics of splsoftclock() to be like other spl*() functions,
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their
XXX spl*() functions are fixed.

dbj 18221f52fc changed dma segment field "ds_read_len" to "ds_xfer_len" since it is valid for
either read or write transfers.

dbj 705311bcee resync bus_dma functions with current alpha versions.
added a field to a dma segment to return the actual length of that segment that
was successfully transferred.

thorpej d721481d50 Make sure the branch target of the delay loop is aligned to a cache
half-line (8-byte) boundary.  Inspired by a discussion w/ Scott Reynolds.

augustss f641c4b3b6 Make two wsmux pseudo devices and add mux locators. 1999-07-29 19:36:58 +00:00
augustss 3652732791 Add wsmux device.
(Also add lots of missing chrtoblktbl[] entries.)

augustss a7cd454b1d It's time to be COMPAT_14. 1999-07-29 10:37:12 +00:00
cgd f886376518 be more efficient when doing the SYSTEM_LD_TAIL for -g kernels: don't
copy them just to strip them, use strip -o.
1999-07-26 05:20:44 +00:00
dbj 15c0ebc780 fixed TAGS target for emacs style tags 1999-07-20 08:55:30 +00:00
christos 41cc9a0eb8 enable PPP_BSDCOMP, PPP_DEFLATE, PPP_FILTER, PFIL_HOOKS, IPFILTER_LOG
on the GENERIC kernels that had them commented out.
XXX: Please note, that not all the kernels have all the options defined!
1999-07-20 07:40:34 +00:00
thorpej 0945bf58b0 Add examples for including the kernel crypto bits from either crypto-us
or crypto-intl, commented out, with instructions to use only one, and
adjust the prefix as necessary.
1999-07-09 18:55:33 +00:00
mrg ecdad0ec33 clean up a bit after jason :)
- fix emitrules() like emitfiles() to deal with the prefix (otherwise it
  would attempt to find the file in the normal base for the NORMAL_C rule).
- add emitincludes() which adds include directives for each prefix to the
  $INCLUDES variable in the makefile.
- add %INCLUDES to each Makefile.arch to deal with the above.

this makes "prefix" actually work in a usable manner, and now i can move
on to fixing compiler warnings (errors) in the ESP code. :)

thorpej 3ebbe095e0 Change the pmap_extract() interface to:
boolean_t pmap_extract(pmap_t, vaddr_t, paddr_t *);
This makes it possible for the pmap to map physical address 0.

dbj fdba65aa8c renamed splscc to splserial to match spl(9) man page
changed most of the spl* to use _splraise to match current usage
this fixes an observed bug where zstty_attach was calling splzs causing
interrupts to be turned on prematurely.

itojun 5effafcaa6 kernel configuration for IPv6/IPsec. should be in GENERIC in the future.
(source code will be committed soon)
1999-07-01 07:00:12 +00:00
itojun 427639cdce - Call ip6intr if INET6 is defined.
- remove "need-flag" for mac68k esp driver, as it is not used in anywhere
  and conflicts with IPsec ESP header.

This should be the only MD change in IPv6 support, except kernel config file.
Very sorry if you have any compilation problem with it (I believe it is okay).
If your favorite arch is not included in here, please add a
call to ip6intr() from softintr handle.

abs b02dbae17e In xxx_mediachange(), if there is no callback to the front-end, just
return 0 instead of EINVAL.  In this case, there will only be one media
type, and the upper-level if_media code will ensure that the user is
setting to that type.
This matches changes Jason made a while back to sys/dev/ic/lance.c

thorpej 0288ffb53a pmap_change_wiring() -> pmap_unwire(). 1999-06-17 19:23:20 +00:00
thorpej f5a527bb4e Remove pmap_pageable(); no pmap implements it, and it is not really useful,
because pmap_enter()/pmap_change_wiring() (soon to be pmap_unwire())
communicate the information in greater detail.
1999-06-17 18:21:21 +00:00
thorpej 602d8e81f7 Don't (ab)use uvm_map_pageable() to allocate PT pages. Instead, do
some internal reference counting on PT pages.  We still allocate them
with the page fault routine (a wire-fault, now), but no longer free
PT pages from pmap_pageable().

kleink 857dfc7058 Slightly rearrange the SSIR inline assembly implementation in order to avoid
making assumptions on C symbol name prefixes.
1999-06-15 15:26:34 +00:00
thorpej 2c35c7bd03 Only declare block major numbers for devices which can be the root device. 1999-06-07 20:31:27 +00:00
thorpej d76e7b8c6d Don't pass a nam2blk around at all; just have setroot() and friends reference
dev_name2blk[] directly.  Addresses PR #7622 (ITOH Yasufumi), although
in a different way.

thorpej beb8d06638 Generally update the comment above vunmapbuf(). 1999-05-26 22:19:33 +00:00
thorpej a2d06a4721 Generally update the comment above the vmapbuf() implementations. 1999-05-26 22:07:36 +00:00
thorpej 2580d306ab Change the vm_map's "entries_pageable" member to a r/o flags member, which
has PAGEABLE and INTRSAFE flags.  PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that.  INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now).  This will eventually
change now these maps are locked, as well.

thorpej 5832084eaf bus_dmamem_map() maps DMA safe memory, which is usually one or more
managed pages, into KVA space.  Since the pages are managed, we should
use pmap_enter(), not pmap_kenter_pa().

Also, when entering the mappings, enter with an access_type of
VM_PROT_READ | VM_PROT_WRITE.  We do this for a couple of reasons:

	(1) On systems that have H/W mod/ref attributes, the hardware
	    may not be able to track mod/ref done by a bus master.

	(2) On systems that have to do mod/ref emulation, this prevents
	    a mod/ref page fault from potentially happening while in an
	    interrupt context, which can be problematic.

This latter change is fairly important if we ever want to be able to
transfer DMA-safe memory pages to anonymous memory objects; we will need
to know that the pages are modified, or else data could be lost!

Note that while the pages are unowned (i.e. "just DMA-safe memory pages"),
they won't consume any swap resources, as the mappings are wired, and
the pages aren't on the active or inactive queues.

lukem e4a87aa1a9 * convert to using MI allocsys(). most ports were using an MD allocsys(),
although a couple still used the old pre-4.4-lite (?) mechanism.
* use format_bytes() to format the various printf()s that print out memory sizes

thorpej f98d358a1f Rework layer 2 protocol input routines. Instead of calling e.g. ether_input()
directly, call the function pointer (*if_input)(ifp, m).  The input routine
expects the packet header to be at the head of the packet, and will adjust
as necessary.  Privatize the layer 2 input and output routines, allowing
*_ifattach() to set them up as appropriate.
