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.
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.
Both models tested and seem to be quite stable and fast.
Thanks to:
- Hans Hubner <hans@Huebner.org> for giving me the cards for testing
- Georg Klug of Syskonnect, who provided me with hw docs for these cards,
very promptly and willingly - I wish all vendors would be like this
- Alfred Arnold, Linux SKNET driver author, for giving me valuable Syskonnect
contact :)
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.
- 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.
interrupts are properly reset on PS/2 now.
Handle the slighly different PS/2 CMOS layout and get/set century
byte as appropriate. The check for valid CMOS CRC checksum is not implemented
yet; I don't currently know algorithm they use.
The info about PS/2 CMOS was taken from the Padgett Peterson's
x86/MSDOS Interrupt List, release 60.
Tested with NE/2 card provided to me by Hans Hubner <hans@Huebner.ORG>.
The Compex and Arco cards were not tested. According to Linux ne2 driver,
they should work same way as NE/2.
and shares some bits with ISA AT1700 driver. Gee, this one was really
easy :)
This card turned out to be quite good performer - I get about 360KB/s
on 386DX PS/2 machine, which is best of all supported cards so far.
and use appropriately
- create more helper macros:
. cdev__xyz_init(c,n), such as cdev__ocri_init() for
/* open, close, read, ioctl */, etc.
. cdev__xRy_init(c,n), where nullop is used instead of enodev to dummy out
method `R' and the comments now read /* xxx (read) yyy */ instead
. cdev__xyz_t_init(c,n,t) - as per cdev__xyz_init, but sets d_type = t
as well
- use seltrue instead of dev_noimpl(poll,*), as (IIRC) cdevsw.d_poll should
always DTRT WRT returning a valid result. (a few devices previously
incorrectly returned ENODEV)
- use dev_noimpl(stop,enodev) instead of dev_noimpl(stop,nullop) if tty
== 0, because it doesn't matter if dev_type_stop isn't implemented in that
case, and it allows the use of the cdev__xyz_init macros. certain ports
(sparc,sparc64,x68k) used the nullop method for dev_type_stop in a few
drivers, whereas everything else uses enodev
- ensure that the comments are accurate WRT the behaviour of a given entry
they keep giving error 0x30b. Unfortunately this keeps happening every second
making the console unusable. Keep track of the last error that occurred and
if the last 10 times apm was called the same error was returned, give up and
exit the apm thread.
WD8003W/A, card provided by David Brownlee (thanks!). The SMC Elite stuff not
tested since I don't have any; hopefully it's correct, should match
information in ADF files.
The MCA-specific init quirk taken from Linux smc-mca.c driver.
I don't quite grok why it works, but it does *cross fingers*.
The WD8003W/A seems to be quite a good choice. I get like 340KB/s on my
machine, where 3c523 does only like 310KB/s. The numbers would be probably
even better with faster CPU than 386DX :)
provided to me by David Brownlee (thanks!).
Performance of this card is quite poor on my PS/2 with 386DX, like 100KB/s
at best, but as low as 5KB/s when transferring bigger files due to
packet overruns. It would be good to revisit this later, probably by
teaching the ic code to use RX Early.
of uvm_fault() to the onfault routine via %eax. users of pcb_onfault now

this allows i/o errors in VOP_GETPAGES() to be returned back to read(), etc.
Remove duplicate prototype for i386_{set,get}_ldt() from sys_machdep.c.
Change i386_iopl() and i386_{set,get}_{ldt,ioperm}() to take a second

revision 1.76. It avoids problems where an I/O interrupt for physio,
using a bounce buffer, would find the destination address mapped
read-only because the syncer process hit.
Suggested by Chuck Cranor.
when the display is closed, the machine suspends (as expected).
when the display is opened again, it resumes and suspends again
(must manually wake).
problem happens because driver fills the event queue with duplicate
events without allowing apmd to drain it by running. fix it by
improving detection of duplicate events.
also cleanup and add some extra APMDEBUG code.
all of the read-only data. Move _etext after all the read-only
data in the LARGEPAGES script, as well.
This will cause const data to actually be const on i386 kernels now
(it was, by sheer luck, on LARGEPAGES kernels simply because of the
section rounding that the LARGEPAGES script performed).
other __HAVE_* defines are). Conditionalize definition of old
disklabel struct and ODIOC* definitions on it, allowing other ports

This is the kernel part (userland to follow soon) of the latest (and
very probably last) release (version 0.96) of ISDN4BSD. ISDN4BSD has a
homepage at http://www.freebsd-support.de/i4b/.
It gives the user various ways to use the isdn connection: raw data (via
the i4brbch "raw b-channel" device), ppp (via the isp "isdn PPP" device),
voice/answering machine (the i4btel "telephone" device) and ip over isdn
(the ipr device, "IP over raw ISDN").
Supported are a bunch of common and older cards, more to be added soon
after some cleanup. Currently only the european E-DSS1 variant of the
ISDN D channel protocol is supported.
tlbflush() when that's what we mean (currently everywhere, except
in the one place in MI code where it is called).
The whole pmap_update() thing needs to be reexamined, but this helps
to clarify things a little with the currently-defined semantics of
that function.
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".
This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

returns for floppy controllers i/o ports. i.e.
1. 1 range of length 4 (which conveniently "forgets" the ctl i/o port),
2. 2 ranges: 1 of length 4 and the ctl i/o port.
3. 1 range of length 6 which goes to the end of the ctl i/o.
Make this line up with the MI fdc code by mapping in a range of 4 on the
base i/o and then either direct or submapping the ctl i/o. In the one case
where the BIOS lies and says it's not there just map it in anyways. (but note
the fact to the end user).
This is very adhoc work for IETF meeting.
- Since it seems that 'an' and 'wi' have similar hardware, low level
functions should be shared.
- There are PCI/ISA cards of Aironet but not supported yet.
- The wiconfig interface is changed so that wiconfig cannot be used.
- 'ancontrol' of FreeBSD is not ported.
- Only infrastructure mode is tested.
- WEP is not supported.
Though I only have an Aironet card, Cisco card should be expected to work.
* __HAVE_SYSCALL_INTERN. If this is defined, e_syscall is replaced by
e_syscall_intern, which is called at key places in the kernel. This can be
used to set a MD syscall handler pointer. This obsoletes and replaces the
*_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL. If this is defined, certain (deprecated) elements in
struct emul are omitted.

Use this in i386 to remove profiling code from the normal userret() path.
this should improve speed of emulation syscall path (avoids one function call,
and emulations syscall can use the trapframe trick)
Idea: Charles Hannum
Remove the EMUL_HAS_SYS___syscall test, because the handler is no longer shared
with SVR4.
Rather than comparing with e_nsysent, just mask the value. This is only done
to protect us from malicious programs anyway.
Also, there is no reason to save the original PC; there are no restartable
syscalls that change the PC -- and even if there were, they wouldn't do it
in the restart case.
* move all exec-type specific information from struct emul to execsw[] and
provide single struct emul per emulation
* elf:
- kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry
per emulation and contains pointer to respective probe function
- interp is allocated via MALLOC() rather than on stack
- elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
part of appropriate execsw[] entry
* constify couple of structures

- MB_LEN_MAX is increased to 32.
- To ensure binary compatibility for old executables
under multibyte locale, versioned setlocale is added.
- __mb_len_cur definision is added in setlocale.c
and enable it in stdlib.h .
It is also important for multibyte locale stuffs,
but I just forgot.
Avoid interpreting the upper 32 bits of 64-bit BARs as a 32-bit BAR.
Otherwise, the code would assume that the value 0 was incorrect and either:
(a) [on bus 0] "fix up" the address to some nonzero value, thus placing
the decoded address range outside of 32-bit address space, or
(b) [elsewhere] completely disable the device.
The fact that this behaviour depends on the bus number of the device is
already XXX'd.

the Following changes are
{Modified with,Approved by} UCHIYAMA Yasushi <uch@netbsd.org>:
- Do not touch a PIRQ router, if the PIRQ is already routed
by the BIOS, or no appropriate IRQ is found for the PIRQ.
The latter prevents a panic on the machine of Frank van der Linden.
- Do not modify a PCI Interrupt Configuration register,
if it is already set by the BIOS, even if it is inconsistent
with the PCI IRQ routing table provided by the BIOS.
(The PCI Interrupt Configuration register seems to be more reliable
than the PCI IRQ routing table.)
This is needed to prevent a incorrect header_fixup() caused
by the incorrect PIR table on a Panasonic Let's Note AL-N2T516J5.
Provide "options PCIBIOS_INTR_FIXUP_FORCE" to retain
previous behavior, i.e. believe the PCI IRQ routing table
and ignore the PCI Interrupt Configuration register.
Although I'm not sure this is really needed.
- Do not modify a PCI Interrupt Configuration register,
if appropriate IRQ is not found for the link.
- Move a pciintr_icu_getclink() call and a pciintr_icu_get_intr()
call from pciintr_link_fixup() to pciintr_link_alloc(),
and only allocate pciintr_link_map if those calls succeeded.
This reduces number of calls of pciintr_icu_getclink(),
and also avoid necessity to validate a clink value in
ICU's {get,set}_{intr,trigger}() functions.
The sanity checks are not removed yet, though.
- Fix uninitialized usage of variable `bitmap' on stage 3
of pciintr_link_fixup().
- Remove a member variable `old_irq' from struct pciintr_link_map.
- Always use 0x%02x for printf format of canonical link value.
- Use DIAGNOSTIC instead of PCIINTR_DEBUG for really weird situation.
