...but still nothing on the PCIC.
The end we want to do selwakeup() on is not necessarily same as the one
we send SIGIO to. Make pipeselwakeup() accept two parameters and update
callers accordingly. This change fixes behaviour for code, which does
select(2)s on the write end waiting for reader (watched on gv, the problem
manifestated itself as a too long delay before the document was displayed).
Clearly separate the resource free code for FreeBSD
and NetBSD case in pipeclose(), so that it's a bit clearer what's going on.
Also LK_DRAIN the lock before the memory is returned to pipe_pool.
Add missing wakeup() in pipe_write() for PIPE_WANTCLOSE case.
Fix promiscuous mode, taken from FreeBSD.
Fix to re-enable the card after suspend/resume.
Reflect current operational rate to if_media interface.
Avoid duplicate copy in transmit.
Move most of debug printfs into IFF_DEBUG.
Disable ANCACHE - designed for IPv4 only and no one use it.
Add IFF_ALLMULTI flags, as we don't have multicast filter.
Convert bzero/bcopy to memset/memcpy.
... sorry for jumbo commit.
This was taken from the PIIX4 manual, and thus doesn't have all
the legacy crap (relative to "modern" ISA PICs, anyway), so if
you have a real i8259 manual, fill in some more bits.
and prom version. Little tweaks to prom during secondary boot are
much easier then fragile work-arounds in the kernel. Currently this
is used for JavaStation 1 with OBP3.
Note: DEBUG checks will not allow accesses to the hole between
text and data segments, so you may need to update programs that
use libkvm before relocating the start of kernel data.
Move the files from footbridge that are cats specific.
Remove EBSA285 kernel as people should be able to use the generic cats kernel for EBSA285 systems.

This makes programs using fts(3) (like find(1)/du(1)) print correct
name again. Problem reported by Luke Mewburn in private e-mail, thanks.
under heavy vnode usage - vget() must be called with unlocked ntnode!
Actually check the vget() return value and DTRT if it fails (i.e. when
the vnode has been recycled for other use).
used to make ELF binaries unmatched by any signature check to be run under
NetBSD 'emulation'. This causes problems like kern/12253.
The old behaviour is available with option EXEC_ELF_CATCHALL.
x86-64. Since there's no hardware available yet, this port is only
known to run on the Simics simulator for at the moment, and as such
uses the PC devices that it simulates for now. It will be developed
more (and cleaned up) as the hardware becomes available.

on all platforms but the i386. On the i386 we look at T_PROTFLT and send
a SIGSEGV instead of SIGBUS. This makes allegro lisp 5.0 and pvs (a proof
verification system) to work.
XXX[1]: We need to go through each architecture and verify that we send
the correct signal on each trap type.
XXX[2]: trap.c on all other architectures but i386 needs to be modified
to s/trapsignal/(*p->p_emul->e_trapsignal)/g
trap/interrupt/syscall entry from userspace.
Remove special-case "by hand" validation of fs/gs register values as
well as special handling of them in various signal handling paths.
Now, like %ds and %es, they are validated by the hardware on return to
userland.
This paves the way for the use of %fs for per-cpu data on
multiprocessor systems, and fixes an otherwise difficult-to-fix
interaction between threads/clone(2) and USER_LDT.
Discussed in advance with Frank van der Linden.
* Really pass PSR ICC bits instead of raw CCR.
* Don't touch ASI and FPRS, which are not part of the 32-bit mcontext.
Also, correct printf conversions in svr4_printmcontext.
Async I/O OS specifities should now handled in OS specific code. Linux
has been done, but other emulation should be handled. See case LINUX_F_SETFL
in sys/compat/linux/common/linux_file.c:linux_sys_fcntl() for more details.

neither it does send any SIGIO for pipes. If async I/O
was requested, we keep the SS_ASYNC in struct socket flag
set, but we clear SB_ASYNC flags on the sending buffer
(for socket), and on the sending and the receiving buffer
(for pipes).
Because we do not alter to SS_ASYNC in struct socket,
the Linux process keeps a consistent view of async I/O
status if it attemps to read the async flag (SS_ASYNC)
This async I/O problem does matters, since some Linux
a programs such as the JDK request async I/O on pipes,
but they fail if they happen to get a SIGIO to the write
end of the pipe.
struct socket so_state field to decide if we need to send asynchronous
notifications. This makes possible to request notification on write but
not on read, and vice versa.
This is used in Linux emulation code, because when async I/O is requested,
Linux does not send SIGIO to write end of sockets, and it never send any
SIGIO to any end of pipes. Il Linux emulation code, we then set SB_ASYNC
only on the read end of sockets, and on no end for pipes.
for FreeBSD project. Besides huge speed boost compared with socketpair-based
pipes, this implementation also uses pagable kernel memory instead of mbufs.
Significant differences to FreeBSD version:
* uses uvm_loan() facility for direct write
* async/SIGIO handling correct also for sync writer, async reader
* limits settable via sysctl, amountpipekva and nbigpipes available via sysctl
* pipes are unidirectional - this is enforced on file descriptor level
for now only, the code would be updated to take advantage of it
eventually
* uses lockmgr(9)-based locks instead of home brew variant
* scatter-gather write is handled correctly for direct write case, data
is transferred by PIPE_DIRECT_CHUNK bytes maximum, to avoid running out of kva
All FreeBSD/NetBSD specific code is within appropriate #ifdef, in preparation
to feed changes back to FreeBSD tree.
This pipe implementation is optional for now, add 'options NEW_PIPE'
to your kernel config to use it.

Now savecore(8) can find core dump in dumpdev properly.

instead to store them. Add a macro to fetch the vaddr without them.
Make all variables/routines prefixed with pmap_
Cleanup & fix some of the vsid bitmap usage.
Cleanup DEBUG printfs. Add some more checks to pmap_pvo_to_pte.
MNT_NOSUID, just check MNT_NOSUID to clear the S{U,G}ID bits
in the attributes for the vnode we're about to exec.
We now check P_TRACED right before we would actually perform
the s{u,g}id function in the exec code.
This closes a race condition between exec of a setuid binary
and ptrace(2).
