the eeprom on common types of memory modules. The specifications are
displayed during boot and can later be queried in the hw.spdmemN sysctl
subtree. Stub driver written by Nicolas Joly and greatly improved upon by
Paul Goyette. From PR 36745, with additional improvements by Paul and me.
(semu + seminfo.semmnu) is wrong, because the type of semu is int*.
You could fix the offset ((char *)semu + seminfo.semusz), but simply
putting the condvars first is more clear.
VOP_LOOKUP ignores LOCKPARENT completely, so make this ignore it also.
XXX: tested only with rump, but I can't really see how this worked
at all before
in its own header file to be included by dkio.h. Fixes breakage due to
pollution from proplib.h in programs which include ioctl.h. Tested and OK
by dogcow@.
"console" to a file system, i.e. a tool for mounting any file system
image supported by rump and executing various commands on it.
Currently it's just a linear set of calls to ukfs routines and
serves mainly as a simple test program and ukfs usage example.
(i.e. no kernel involvement), namely:
* create, mknod, remove, mknod, rmdir, getdents, read, write, and link
Still obviously missing a few, but this is a start (I'm also searching
for the blessed orb of code quality, maybe someone has seen it?).
-> the current names are confusing (didn't change other drivers)
* fix invalid memory access in usbd_transfer (kern/24636)
-> needed for this driver
* fix USB HC detach race condition (kern/32011)
-> main patch needed for this driver, sc_dying changes in other drivers
not necessary but seem right to me
Patch from Matthew Orgass.

lwp_exit() before suspending. In such case, LWP might be already freed after
cv_wait_sig() and checking the list of LWPs via lwp_find() is necessary.
Possible problem catched by Andrew Doran.
especially if that other expression is the right hand side operand of
&& which is short-circuiting. The effect was that audiorecord(1)
would always fail trying to set recording port with AUDIO_SETINFO.
Tested on wss@pnpbios. It looks like this problem has been reported
as PR/35239, filed against port-hp700.

In irq_setmasks(), refer spl_masks[current_spl_level] directly
rather than spl_mask which is a saved value in splraise() and
splx() functions because the latter one is not always sync'ed with
current_spl_level and interrupt state could be mangled.

Okay'ed by chris@, and should close PR port-shark/22355.
checking for a readonly lookup. This shouldn't make a difference
now, though, as the only RDONLY lookup is done by getcwd(), and
that a) doesn't create files b) calls LOOKUP directly anyway.
Also, fix comment I managed to miss in the previous commit (I didn't
expect the same comment to be there twice).
system faulting in pages if it does e.g. fragment reallocation
* get rid of rumpvm_findpage() and always use uvm_pagelookup()
* determine a vnode's cleanness by flagging it as being on the work
list if we "take" a write fault and removing it from the worklist
once pages are flushed. There is no work list here, but at least
there is symmetry with the kernel.
especially the Bridge Control Register definition, instead of
rolling its own.
As we read/modify/write configuration registers, use a variable
that is named for the register we're r/m/w'ing, instead of using
the variable 'reg' over and over. This helps both a human reader
verify that we're not reading register X, modifying it, and writing
back to register Y (oops); the compiler can help a little by warning
that a variable is used before it is initialized.
it possible to get the pid, euid and egid of the process at the remote
end at the time it did bind() or connect().
Add a new libc function, getpeereid() to easily get at the euid and egid.
As a consequence, bump libc's minor number.
Document the LOCAL_PEEREID socket option in unix(4).
Based on contribution by Arne H. Juul, minor modifications by myself.
ffs in userspace on top of puffs/p2k/rump is now stable enough to
host a make -j4 kernel build (well, at least my kernel build ...
but, yes, I am currently running that kernel on my desktop)
any real trickery. Unfortunately this was the easy part; r/w
support is going to make ascending naked, blind, illiterate, without
food and as an atheist look trivial.
introduce vrele2(), which allows to release vnodes the way lfs
sometimes wants it:
+ without calling inactive
+ inserting the vnode at the head of the freelist (this is a very
questionable optimization that isn't even enabled by default,
but I went along with the same semantics for now)
in platform dependent init functions.
arc_init_wired_map() refers ipl_sr_bits[] via
extent_create(9) -> mutex_init(9) -> makeiplcookie(9)
since the partial merge of vmlocking.
directly instead of relying on a symbol in rumpkern. I would like
to make it call the libc symbol directly, but I don't currently know
how to make it do that MI.
Makes hfs work (on i386), as it avoids endless recursion in bswap64().
Thanks to dillo for the image!
I like it better because I get to see the name of the device as it appears
in the DSDT, which sometimes makes sense and that way it's easier to locate
the relevant code when debugging.
E.g.:

pckbc0 at acpipcib0 (PS2K, PNP0303): kbd port
acpibat0 at acpi0 (BAT0, PNP0C0A-0): ACPI Battery (Control Method)
- mark (DIS)CHARGERATE as invalid when (DIS)CHARGING so that envstat
doesn't print some weird stats where the system appears to be doing
both
- handle the case when it's doing neither by marking *RATE as invalid
and setting CHARGING to OFF (because we're not charging, even though
we're not discharging)
- fix print_stats to print correct values in those cases, and a real
percentage (i.e., computed against LFCCAPACITY)
1 microsecond into the future, the thread could enter an untimed sleep.
- Change the signature of _lwp_park() to accept an lwpid_t and second
hint pointer, but do so in a way that remains compatible with older
pthread libraries. This can be used to wake another thread before the
calling thread goes asleep, saving at least one syscall + involuntary
context switch. This turns out to be a fairly large win on the condvar
benchmarks that I have tried.
- Mark some more syscalls MP safe.
