chs 821ec03ed9 replace vm_map{,_entry}_t with struct vm_map{,_entry} *. 2001-06-02 18:09:08 +00:00
matthias 0319a3d7bf Add a missing line from i386/i386/pmap.c to make this work again. 2001-06-02 16:47:17 +00:00
lukem d84d2c6c85 add missing #include "opt_kgdb.h" 2001-05-30 15:24:23 +00:00
mrg 67afbd6270 use _KERNEL_OPT 2001-05-30 11:57:16 +00:00
mrg 3783ca5d30 define _KERNEL_OPT as well as _KERNEL. we will use this in the future to
get kernel "opt_foo.h" headers, rather than _KERNEL && !_LKM.

scw 2963ff5c58 Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point
in each tty driver to indirect through it.

This allows tty line-disciplines to handle poll(2) system calls.

thorpej cf67ac7122 Per discussion w/ chuck and chuck, restructure the md page stuff
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.

thorpej 2b27ac7a99 Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
each vm_page structure.  Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM.  These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg.  As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now).  Changes to other pmap
modules will follow.

kleink fe3c9ceaf7 * Move definitions of exact-width integer types from <machine/types.h>
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
  explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
  macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
  intmax_t, pointer-type and size_t arguments.

bouyer 937a7a3ed9 Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
  ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
  to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
  peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
  recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
  scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
  (no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
  set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
  the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
  will be requeued, or a REQUEST SENSE will be sent as appropriate.

thorpej d7e12660a3 Work around the problem that causes kern/12554. Basically,
there are some pathological cases that cause pmap_page_protect()
to be called on a wired page to revoke all mappings.  We
need to skip mappings that are actually wired to prevent Bad
things from happening later.

THIS IS JUST A WORK-AROUND.  We need to prevent the pathological
behavior from happening in UVM to begin with.  But it's unclear
what the right solution is there, right now.

thorpej 1c3a62e066 Sprinkle pmap_update() calls after calls to:
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).

These calls are relatively conservative.  It may be possible to
optimize these a little more.

thorpej 55044638aa Remove pmap_kenter_pgs(). It was never really adopted by
anything, and the interface itself wasn't as flexible as
callers would have probably liked.
2001-04-22 23:42:11 +00:00
thorpej ec66f67f3a Use pmap_kenter_pa() rather than pmap_kenter_pgs(). 2001-04-22 23:28:52 +00:00
thorpej 69abdbf60c Undo a misguided previous change to the pmap_update() API. 2001-04-22 23:19:26 +00:00
thorpej 4738622712 Give pmap_update() an argument (a pmap_t) so that it knows which
pmap it should be updating.

thorpej bf2dcec4f5 Remove the use of splimp() from the NetBSD kernel. splnet()
and only splnet() is allowed for the protection of data structures
used by network devices.

kleink 9133b51cd8 Replace the 'unsigned __COMPILER_INT64__' construct with a new name,
__COMPILER_UINT64__, to be supplied - if such a case is made, it shouldn't
be assumed that the unsigned type-specifier may be applied to it.

chs ac3bc537bd eliminate the KERN_* error codes in favor of the traditional E* codes.
the mapping is:

KERN_SUCCESS			0
KERN_INVALID_ADDRESS		EFAULT
KERN_PROTECTION_FAILURE		EACCES
KERN_NO_SPACE			ENOMEM
KERN_INVALID_ARGUMENT		EINVAL
KERN_FAILURE			various, mostly turn into KASSERTs
KERN_RESOURCE_SHORTAGE		ENOMEM
KERN_NOT_RECEIVER		<unused>
KERN_NO_ACCESS			<unused>
KERN_PAGES_LOCKED		<unused>

fvdl c7f1462f3e Add machdep file for procfs. Currently only used for linux-style
/proc/cpuinfo (only active when procfs is mounted with -o linux).
For ports other than the i386 this currently produces an empty
string.

thorpej d85a75f583 Make sure everybody has an splvm() and equate it with splimp() (splimp()
is the historical name for this interrupt level, and the historical name
is going to go away in the near future).
