amap_free(): Assert that the amap is locked.
amap_share_protect(): Assert that the amap is locked.
amap_wipeout(): Assert that the amap is locked.
uvm_anfree(): Assert that the anon has a reference count of 0 and is
not locked.
uvm_anon_lockloanpg(): Assert that the anon is locked.
anon_pagein(): Assert that the anon is locked.
uvmfault_anonget(): Assert that the anon is locked.
uvm_pagealloc_strat(): Assert that the uobj or the anon is locked
And fix the problems these have uncovered:
amap_cow_now(): Lock the new anon after allocating it, and unref and
unlock it (rather than lock!) before freeing it in case
of an error condition. This should fix a problem reported
by Dan Carosone using cdrecord on an i386 MP kernel.
uvm_fault(): Case1B -- Lock the new anon afer allocating it, and unlock
it later when we unlock the old anon.
Case2 -- Lock the new anon after allocating it, and unlock
it later by passing it to uvmfault_unlockall() (we set anon
to NULL if we're not doing a promote fault).
NULL "name" argument to irq_establish indicates that the device will maintain
an evcnt structure for this interrupt. In this case, irq_establish will still
maintain its own count (for DDB machine irqstat), but won't attach it to the
global list.
Change use of ev_group and ev_name to follow guidelines in evcnt(9).
Switch arckbd(4) over to the new arrangements.
This adds support for EtherExpress/16 cards with 16k of RAM, and in the
process adds general support for PIO mode on these cards. This entails
changing the way the i82586 driver handles bus barriers, since it doesn't
allow for strange cases like this.
This has been tested on the i386 port with the 'ix' driver in both
16KB (which was the source of the problem) and 32KB modes, as well
as with the 'ef' driver. I've tested it (briefly) with 'ei' on arm26
as well. In theory, drivers other than 'ix' should follow precisely the
same code paths as before.
following links, hence is usable for checking of presence of a symlink.
Also slighly cleanup EXISTS and CREAT cases - use symbolic constants
instead of 0/1.
This is needed for emulation of readlink(2), lchown(2) and similar.
Addresses kern/11757.
do not return junk data in mbuf (= sockaddr on accept(2)'s 2nd arg).
set the length zero.
behavior checked with bsdi and freebsd.
partial solution to PR 12027 and 10698 (need more investigation).
and link it directly to db_command_table[] so that it's not necessary
to do this at runtime. Make db_machine_command_table[] const on all ports.
g/c now unneded stuff, like db_machine_commands_install(), db_machine_init()

and number of ops, not touch anything - vnode_if.sh now generated
proper offset numbers; vfs_op_check() is only defined and called for DEBUG
kernels
constify extern declaration of vfs_op_descs[]
g/c vfs_opv_numops, use VNODE_OPS_COUNT instead
make vfs_opv_init_explicit() and vfs_opv_init_default() static
then don't need to be patched at runtime
add new define VNODE_OPS_COUNT (to vnode_if.h) so that the number is known
at compile-time
make stuff const, it now can be
Because zeroing them causes zero division panic with devices which don't
support 8kHz mulaw, and the effect of this line was to force calling
audio_calcwater even when unnecessary.
since we do not have feedback mechanism from path MTU to tunnel MTU
(not sure if we should), and inner packet source will not get informed of
outer PMTUD (we shouldn't do this), 1.15 behavior can lead us to
blackhole behavior.
configurable behavior (as suggested in RFC2401 6.1) would be nice to have,
however, reusing net.inet.ipsec.dfbit would be hairy.
is fussy about the order of sections and location of memory gaps so we
must produce a firmware friendly version of the kernel as netbsd.ecoff for
network booting
The ELF version uses the standard mips linker script which can be loaded
by the new bootstrap routines
The only thing stopping us from getting totally rid of the evil
USBD_NO_TSLEEP hack is the (broken) assumption in the MII driver that
registers can be read and written without a process context.
USB device discovery, now it can also perform (short) tasks for device
drivers that need a process context, but don't have one.
This is not pretty, but better than using busy-wait in an interrupt context.
* Get rid of `#ifdef FreeBSD'; they seem to maintain their own version.
* Change watchdog code (from FreeBSD).
* Get rid of the horrible USBD_NO_TSLEEP hack.
* Repair some const damage.
- status stay in touching while pen don't realy touch.
- cursor often jumps to center of screen.
But it seems that 'stay in touching' still occurs at rare intervals.
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.
shape as the old arm32 one, but there are a few #defines to keep arm26 code
happy. Anything that depends on the precise shape of the trapframe,
and especially on being able to treat it as an array of registers, has been
updated.
a constant PAGE_SIZE value didn't include setting the UVM pagesize, and the
attempt to add this ended up in the wrong place. Amiga should now boot
again.
enough, e.g. it has been initialized already by inittodr() or set
explicitly before by resettodr(). This prevents the TOD clock from going
way backwards when typing `halt' at the `mount root filesystem' prompt.
o Add NAKAGAWA METAL's LNT-10TN card.
o Add KINGSTON KNE-PC2 ethernet card.
o Add RATOC REX_R280 card.
o Add $FreeBSD$ id.
I've not added these cards the their respective drivers, however.
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).
