kleink dadbb7e784 There is no extended-precision format on sh3. 2001-05-03 13:19:52 +00:00
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.
 2001-05-01 02:19:13 +00:00
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.

kleink 99054d7a6c Add definitions for C99 fastest minimum-width integer types. 2001-04-26 16:25:19 +00:00
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.

uch 63ec3bc3fa dreamcast clock module was separated. 2001-04-23 11:20:41 +00:00
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 69abdbf60c Undo a misguided previous change to the pmap_update() API. 2001-04-22 23:19:26 +00:00

uch 95f0d5c680 add RTC control register 1 defines. 2001-04-22 16:50:17 +00:00
thorpej 4738622712 Give pmap_update() an argument (a pmap_t) so that it knows which 
pmap it should be updating.
 2001-04-22 00:33:59 +00:00
thorpej 15f731ee94 pmap_update() should not be equated with "flush entire TLB", it is 
used to process deferred pmap operations.  Since these pmaps don't
defer anything, pmap_update() is a noop.

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.

chs e47583af2c missed some KERN_FAILUREs. 2001-03-18 23:43:53 +00:00
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>

itohy 7ffa2a0375 Add RTC_OFFSET support to inittodr() on dreamcast. 
No changes to other sh ports.

thorpej 51aeeceeaf Clean up TLB trap handling a little. 
- When printing a user trap, include p->p_comm in the message.
- In the TLB fault handler, don't just go charging along if
  the fault can't be handled.  If we get a fatal kernel TLB
  fault, we need to panic!  Or, if DDB is enabled, call the
  Debugger().

msaitoh 0aa1f3d01e modify target name because we can't recommend to use pkgsrc/cross

msaitoh bba3f2423b add comment about $CPP 
From source:

# XXX following definition is absolutely incorrect.
# Our cpp is not /usr/libexec/cpp but /usr/bin/cpp.
# True solution is:
#	1) copy /usr/bin/cpp into /usr/local/bin/sh-*-*-cpp
#	2) Edit CPP in sh-*-*-cpp correctly
#		(e.g. "CPP=`$CC -print-prog-name=cpp`").
#	3) Edit STDINCDIR in sh-*-*-cpp correctly
#		(e.g. STDINCDIR=/usr/local/sh-unknown-netbsdcoff/include)

# BROKEN
CPP=`$TARGET-gcc -print-prog-name=cpp`

# EXAMPLE
#CPP=/usr/local/bin/sh-unknown-netbsdcoff-cpp
#CPP=/usr/local/bin/sh-unknown-netbsdelf-cpp

thorpej c8cdb12913 Add some comments about P/USEG 2001-02-02 18:25:04 +00:00
thorpej ef2315d256 Rewrite how mod/ref emulation is done. In particular, make 
modified attribute checking actually work.  Previously, a
page could be reported as modified even if it wasn't!  This
is very bad, and e.g. caused the VM system to attempt to
"clean" pages of read-only files.

Only lip-services is paid to referenced attribute emulation.
This could be improved.

big endian assembler, sometimes.  explicitly have -little to specify
