In such case it increases 'pace' counter on each ENOMEM and reschedules the request. The 'pace' counter is decreased for each request going down, but until 'pace' is greater than zero, GEOM will handle at most 10 requests per second. For GEOM GATE users that are proxy to local GEOM providers (like ggatel(8) and HAST) we can end up with almost permanent slow down of GEOM down queue. This is because once we reach GEOM GATE queue limit, we return ENOMEM to the GEOM. This means that we have, eg. 1024 I/O requests in the GEOM GATE queue. To make room in the queue and stop returning ENOMEM we need to proceed the requests of course, but those requests are handled by userland daemons that handle them by reading/writing also from/to local GEOM providers. For example with HAST, a new requests comes to /dev/hast/data, which is GEOM GATE provider. GEOM GATE passes the request to hastd(8) and hastd(8) reads/writes from/to /dev/da0. Once we reach GEOM GATE queue limit, to free up a slot in GEOM GATE queue, hastd(8) has to read/write from/to /dev/da0, but this request will also be very slow, because GEOM now slows down all the requests. We end up with full queue that we can unload at the speed of 10 requests per second. This simply looks like a deadlock. Fix it by allowing userland daemons that work with both GEOM GATE and local GEOM providers to specify unlimited queue size, so GEOM GATE will never return ENOMEM to the GEOM.

Translate the meaningless EAGAIN to ETIMEDOUT to give administrator a hint that he might need to increase timeout in configuration file. r220273 (pjd): Handle ENOBUFS on send(2) by retrying for a while and logging the problem. r220274 (pjd): Increase default timeout from 5 seconds to 20 seconds. 5 seconds is definitely to short under heavy load and I was experiencing those timeouts in my recent tests.

Log:
  If building (custom) FreeBSD images people tend to patch param.h.  In case
  this happens just before the build is started (within the same second)
  CHECK_TIME actually triggers thinking param.h is in the future (see f_Xtime,
  c_Xtime logi in find(1) sources for the details in !F_EXACTTIME case).
  Using the -mtime -0s (seconds, rather than no unit) avoids this 1s race.

  We don't need to call EOWRITE4(sc, EHCI_USBINTR, 0) directly from each EHCI
  bus driver at detach, hence ehci_detach() does exactly this since r199718.

Log:
  Introduce geom_map, a GEOM provider designed for use by
  embedded flash stores.
  
  Some devices - notably those with uboot - don't have an
  explicit partition table (eg like Redboot's FIS.)
  geom_map thus provides an easy way to export the hard-coded
  flash layout as geom providers for use by filesystems and
  other tools.
  
  It also includes a "search" function which allows for
  dynamic creation of partition layouts where the device only
  has a single hard-coded partition. For example, if
  there is a "kernel+rootfs" partition, a single image can
  be created which appends the rootfs after the kernel with
  an appropriate search string. geom_map can be told to
  search for said search string and create a partition
  beginning after it.

  Implement automatic SCSI sense fetching for ata(4) in ATA_CAM mode.
  While it could be successfully done by CAM error recovery code, I was
  told by several people that it is also a SIM obligation.

Just so you're aware, there's also another EHCI driver in the tree at 
/sys/powerpc/ps3/ehci_ps3.c. It might also need some modifications at 
various points when you're cleaning up EHCI drivers.

This driver doesn't have a detach method. The patches don't apply to this 
driver then. Should I add a detach method or is it superfluous?

Thanks for noticing!

New Revision: 220576
URL: http://svn.freebsd.org/changeset/base/220576

Log:
  Refactor hard-reset implementation in ahci(4).
  
  Instead of spinning in a tight loop for up to 15 seconds, polling for device
  readiness while it spins up, return reset completion just after PHY reports
  "connect well" or 100ms connection timeout. If device was found, use callout
  for checking device readiness with 100ms period up to full 31 second timeout.
  
  This fixes system freeze for 5-10 seconds on drives hot plug-in.

New Revision: 220577
URL: http://svn.freebsd.org/changeset/base/220577

Log:
  Add a new tunable 'machdep.disable_tsc_calibration' to allow skipping TSC
  frequency calibration.  For Intel processors, if brand string from CPUID
  contains its nominal frequency, this frequency is used instead.

Log:
  Do not use TSC for DELAY(9) if it not P-state invariant to avoid possible
  foot-shooting.  DELAY() becomes unreliable when TSC frequency varies wildly,
  especially cpufreq(4) and powerd(8) are used at the same time.

Log:
  Add support for IEE/IEC (and now also SI) power of two notions of
  prefixes (Ki, Mi, Gi...) for humanize_number(3).
  
  Note that applications has to pass HN_IEC_PREFIXES to use this
  feature for backward compatibility reasons.

Log:
  Reinstate cpu_est_clockrate() support for P-state invariant TSC if APERF and
  MPERF MSRs are available.  It was disabled in r216443.  Remove the earlier
  hack to subtract 0.5% from the calibrated frequency as DELAY(9) is little
  bit more reliable now.

  Fix a couple of mbuf leaks introduced by r217242. I do
  not believe that these leaks had a practical impact,

  would have been extremely rare.

New Revision: 220586
URL: http://svn.freebsd.org/changeset/base/220586

Log:
  - Fix the code that matches userids in match_jobspec().  It needs to check
    the username-for-accounting field (P), not the username-for-headerpage (L).
    These are usually the same value, except that control files do not have
    the username-for-headerpage field if the user has requested no header page.
  - Also rename the cji_username field to cji_headruser, to make it clear that
    the value should only be used for the header page.  (aka banner page)

Log:
  Port over a TX gain fix from ath9k specific to the AR9285 (Kite) and AR9271.
  Note: this HAL currently only supports the AR9285.
  
  From Linux ath9k:
  
  The problem is that when the attenuation is increased,
  the rate will start to drop from MCS7 -> MCS6, and finally
  will see MCS1 -> CCK_11Mbps. When the rate is changed b/w
  CCK and OFDM, it will use register desired_scale to calculate
  how much tx gain need to change.
  
  The output power with the same tx gain for CCK and OFDM modulated
  signals are different. This difference is constant for AR9280
  but not AR9285/AR9271. It has different PA architecture
  a constant. So it should be calibrated against this PA
  characteristic.
  
  The driver has to read the calibrated values from EEPROM and set
  the tx power registers accordingly.

Log:
  As soon as siis_reset() doesn't waits for device readiness, but only for
  controller port readiness (that should set just after PHY ready signal),
  reduce wait time from 10s to 1s before trying more aggressive reset method.
  
  This should improve system responsibility in some failure conditions.

Typo.

> +	TUNABLE_INT_FETCH(announce_buf, &softc->write_cache);

TUNABLE_INT_FETCH() uses getenv() which may sleep (due to M_WAITOK
allocation). You will get a witness warning (see below) on a WITNESS
enabled kernel because the sim mutex is held in adaregister(). The
tunable must exist, otherwise getenv() doesn't allocate memory.

cd(4) has the same problem for kern.cam.cd.%d.minimum_cmd_size tunable
and da(4) for kern.cam.da.%d.minimum_cmd_size tunable.

I am considering adding WITNESS_WARN() to getenv() to expose these bugs
early.

uma_zalloc_arg: zone "16" with the following non-sleepable locks held:
exclusive sleep mutex ATA state lock (ATA state lock) r = 0 (0xc42e0174) locked @ /home/jaakko/src/head/sys/cam/cam_xpt.c:1991

Log:
  More kite diversity related changes.
  
  * add a diversity flag to the HAL debugging section
  * add a check to make sure the kite diversity code doesn't run
    on boards that don't require it, as not all Kite chips will
    implement it.
  * add some debug statements when the diversity code makes
    changes to the antenna diversity/combining setup.

Log:
  Add in the AR9285 (Kite) diversity to if_ath, enabling TX/RX antenna
  diversity.
  
  This is bit dirty and likely should be revised at a later date,
  with an eye to unifying/tidying up the whole diversity setup
  and allowing developers to do "tricky stuff" as they desire.
  For now, this works.

I'm sorry for not finding time to review this change before your commit,
but I do have some comments.

Before I get to the code, I'd like to state that I fully agree with
Andrew Thompson that having 4GB limit is really wrong. We had this
bigdisk project for a long time trying to remove all such old
assumptions about disk sizes and committing a GEOM class that have a
limit of 4GB for media size is really wrong direction. We should really
treat this as a policy for new GEOM classes. Changing GEOM_MAP to work
with 64bit offsets is not a big change and I'd really like to see it
being committed. Maybe Aleksandr (CCed) would like to work on this?

Spaces here should be replaced with tabs.

I'd remove white-spaces between array name and size. Also in other
places.

This can be removed. If the ioctl method is not specified, GEOM will
return ENOIOCTL for you.

Two spaces instead of one. You can also think about moving
initializations below declarations.

Tabs instead of single space.

This should look like this:

		if (g_handleattr_int(bp, MAP_CLASS_NAME "::entry",
		    sc->entry[idx])) {
			return (1);
		}
		if (g_handleattr_int(bp, MAP_CLASS_NAME "::dsize",

			return (1);
		}

The line should be started with four spaces.

White-spaces need cleanups.

Three 'const char *' should use single line.

uint32_t is preferred over u_int32_t and only one of them should be used
for consistency.

strcmp() doesn't return bool, it returns int so should be compared to 0.

Four spaces.

Why do you drop the topology lock here? Seems wrong.

'ret' is not bool.

strncmp() is not bool.

Four spaces.

Is this a leftover debug printf?

Four spaces.

It is better to drop the topology lock when doing g_read_data().

> +				if (buf !=3D NULL && strncmp(
> +					buf + search_offset % sectorsize,=20
> +					key, strlen(search_key)) =3D=3D 0)

This is good example why do we use four spaces to continue previous
line. In the above code it is hard to see where the diff ends and where
the code begins.

> +			ret =3D resource_int_value("map", i, "searchstart", &search_start);

First 'ret' is not checked.

> +				buf =3D g_read_data(cp,=20
> +					rounddown(search_offset, sectorsize),=20
> +					roundup(strlen(search_key), sectorsize),=20

Again, it is better to drop the topology lock.

First and second 'ret' is not checked.

Is this a leftover debug printf?

Four spaces.

Four spaces.

Not need to separate cast and variable with space.

> +				__func__, error, name);

Leftover debug printf?

Redundant empty line before 'if'.

Seems to be a no-op. GEOM can cope if this method is not specified.

New Revision: 220602
URL: http://svn.freebsd.org/changeset/base/220602

Log:
  Improve SATA Asynchronous Notification feature support in CAM:
   - make SATA SIMs announce capabilities to handle SDB with Notification bit;
   - make PMP driver honor this SIMs capability;
   - make SATA XPT to negotiate and enable this feature for ATAPI devices.
  
  This feature allows supporting SATA ATAPI devices to inform system about
  some events happened, that may require attention. In my case this allows
  LG GH22LS50 SATA DVR-RW drive to report tray open/close events. Events
  reported to CAM in form of AC_SCSI_AEN async. Further they could be used
  as a hints for checking device status and reporting media change to upper
  layers, for example, via spoiling mechanism of GEOM.

 ----------------------------------------
+13 April 2011. Summary of changes for version 20110413:
+
+1) ACPI CA Core Subsystem:
+
+Implemented support to execute a so-called "orphan" _REG method under the EC 
+device. This change will force the execution of a _REG method underneath the EC 
+device even if there is no corresponding operation region of type 
+EmbeddedControl. Fixes a problem seen on some machines and apparently is 
+compatible with Windows behavior. ACPICA BZ 875.
+
+Added more predefined methods that are eligible for automatic NULL package 
+element removal. This change adds another group of predefined names to the list 
+of names that can be repaired by having NULL package elements dynamically 
+removed. This group are those methods that return a single variable-length 
+package containing simple data types such as integers, buffers, strings. This 
+includes: _ALx, _BCL, _CID,_ DOD, _EDL, _FIX, _PCL, _PLD, _PMD, _PRx, _PSL, _Sx, 
+and _TZD. ACPICA BZ 914.
+
+Split and segregated all internal global lock functions to a new file, evglock.c.
+
+Updated internal address SpaceID for DataTable regions. Moved this internal space 
+id in preparation for ACPI 5.0 changes that will include some new space IDs. This 
+change should not affect user/host code.
+
+Example Code and Data Size: These are the sizes for the OS-independent acpica.lib 
+produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug version of 
+the code includes the debug output trace mechanism and has a much larger code and 
+data size.
+
+  Previous Release (VC 9.0):
+    Non-Debug Version:  89.8K Code, 23.8K Data, 113.6K Total
+    Debug Version:     164.2K Code, 67.9K Data, 232.1K Total
+  Current Release (VC 9.0):
+    Non-Debug Version:  90.0K Code, 23.8K Data, 113.8K Total
+    Debug Version:     164.5K Code, 68.0K Data, 232.5K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL/DTC: Major update for new grammar features. Allow generic data types in 
+custom ACPI tables. Field names are now optional. Any line can be split to 
+multiple lines using the continuation char (\). Large buffers now use line-
+continuation character(s) and no colon on the continuation lines. See the grammar 
+update in the iASL compiler reference. ACPI BZ 910,911. Lin Ming, Bob Moore.
+
+iASL: Mark ASL "Return()" and the simple "Return" as "Null" return statements. 
+Since the parser stuffs a "zero" as the return value for these statements (due to 
+the underlying AML grammar), they were seen as "return with value" by the iASL 
+semantic checking. They are now seen correctly as "null" return statements.
+
+iASL: Check if a_REG declaration has a corresponding Operation Region. Adds a 
+check for each _REG to ensure that there is in fact a corresponding operation 
+region declaration in the same scope. If not, the _REG method is not very useful 
+since it probably won't be executed. ACPICA BZ 915.
+
+iASL/DTC: Finish support for expression evaluation. Added a new expression parser 
+that implements c-style operator precedence and parenthesization. ACPICA bugzilla 
+908.
+
+Disassembler/DTC: Remove support for () and <> style comments in data tables. Now 
+that DTC has full expression support, we don't want to have comment strings that 
+start with a parentheses or a less-than symbol. Now, only the standard /* and // 
+comments are supported, as well as the bracket [] comments.
+
+AcpiXtract: Fix for RSDP and dynamic SSDT extraction. These tables have "unusual" 
+headers in the acpidump file. Update the header validation to support these 
+tables. Problem introduced in previous AcpiXtract version in the change to 
+support "wrong checksum" error messages emitted by acpidump utility.
+
+iASL: Add a * option to generate all template files (as a synonym for ALL) as in 
+"iasl -T *" or "iasl -T ALL".
+
+iASL/DTC: Do not abort compiler on fatal errors. We do not want to completely 
+abort the compiler on "fatal" errors, simply should abort the current compile. 
+This allows multiple compiles with a single (possibly wildcard) compiler 
+invocation.

Log:
  Add a new DDB command, "show rmans", which will show the address and brief
  details of each rman header, but not the contents of all rman structures
  in the system.  This is especially useful on platforms where some rmans
  have many thousands of entries in rmans, making scrolling through the
  output of "show all rman" impractical.  Individual rmans can then be viewed
  including their contents with "show rman 0xaddr" as usual.

Log:
  MFC: 220152
    This patch fixes the Experimental NFS client to properly deal with 32 bit or
    64 bit fileid's in NFSv2 and NFSv3. Without this fix, invalid casting (and sign
    extension) was creating problems for any fileid greater than 2^31.
  
    We discovered this because we have test clusters with more than 2 billion
    allocated files and 64-bit ino_t's (and friend structures).

Hmm...  on my VMs this now leads to:

Ah, I failed to notice the commit that came before, r220583.
Apparently, it can happen (at least in a VM environment) that the
DELAY(1000) in this fragment from cpu_est_clockrate():

                 wrmsr(MSR_MPERF, 0);
                 wrmsr(MSR_APERF, 0);
                 tsc1 = rdtsc();
                 DELAY(1000);
                 mcnt = rdmsr(MSR_MPERF);
                 acnt = rdmsr(MSR_APERF);
                 tsc2 = rdtsc();
                 intr_restore(reg);
                 perf = 1000 * acnt / mcnt;

will still read 0 from MSR_MPERF, leading to a division by zero.  Maybe
just fallback to the second method in the 'else' branch then?

New Revision: 220610
URL: http://svn.freebsd.org/changeset/base/220610

Log:
  Fix the experimental NFSv4 client so that it recognizes server
  mount point crossings correctly. It was testing the wrong flag.
  Also, try harder to make sure that the fsid is different than
  the one assigned to the client mount point, by hashing the
  server's fsid (just to create a different value deterministically)
  when it is the same.

That means your VM has broken CPUID support.  To get there, it has to 
meet two conditions, i.e., TSC is invariant and it has APERF/MPERF 
MSRs.  A simple workaround is setting "machdep.disable_tsc=1" 
tuanable from loader but your VM is the real culprit here.

    Yeah, it kind of peeves me that this kind of rinky dink stuff is
done with VMware ESXi, etc (fake RAM returning 0MHz in the SMBIOS
table in certain scenarios).

    VMware ESXi lies on multiple fronts in this area I've discovered
lately at $WORK, in particular the SMBIOS / FreeBSD are calling CPUID
which is returning info based on the host processor instead of the
emulated guest processor, which in turn is causes minor problems in
our software. Example being that the host processor is a Intel
Woodcrest CPU (this is what an in-house tool and FreeBSD reports)
instead of a Pentium Pro emulated CPU (that's what dmidecode reports
and that's what ESXi emulates).
    Wasn't happy about this breakage and someone should probably talk
to VMware about fixing their emulation software so that it tells a
consistent story across the board.
Thanks,

Yeah, it is really shame that VMware (and others) suck in this area.  
VMware just exposes nominal frequency of the host CPU (or user can 
configure it) and advertises it is constant.  Then, RDTSC instruction 
is trapped and scaled at the fixed frequency.  On the other hand, 
VirtualBox has a different problem, e.g., TSC does not scale 
properly.  I think it just detects the *current* frequency of the 
host CPU and never changes even if host clock frequency changes.  I 
believe you can just disable TSC in VM guest and use other clock 
sources until they fix the problems.  AFAIK, virtualized TSC has no 
benefit over other clock sources, unlike real hardware anyway.

Author: obrien
Date: Wed Apr 13 23:09:36 2011
New Revision: 220612
URL: http://svn.freebsd.org/changeset/base/220612

Log:
  MFC: r220370, r209136, r209219
  
  * Add the readline(3) API to libedit.  The libedit versions of
    {readline,history}.h are in /usr/include/edit so as to not conflict with
    the GNU libreadline versions.  To use the libedit readline(3) one should
    add "-I/usr/include/edit" to their Makefile
    (spelled "-I${DESTDIR}/${INCLUDEDIR}/edit" within the FreeBSD source tree).
  * Enable its use in the BSD licensed utilities that support readline(3).
  * histedit.h is moved into libedit's directory
  
  * Add basic filename completion code.
  * Allow simple quoting in filename completion.

New Revision: 220615

Log:
  Refactor hard-reset implementation in mvs(4).
  
  Instead of spinning in a tight loop for up to 15 seconds, polling for device
  readiness while it spins up, return reset completion just after PHY reports
  "connect well" or 100ms connection timeout. If device was found, use callout
  for checking device readiness with 100ms period up to full 31 second timeout.
  
  This fixes system freeze for 5-10 seconds on drives hot plug-in.

You are probably right but fixing VMs is not going to happen (or not
soon enough) so workarounds must be implemented.

I don't know if it is called early enough for this purpose, but
detect_virtual() in kern/subr_param.c initializes the vm_guest
variable which could be useful for such workarounds (also see how
vm_guest is used in init_param1() in the same file to scale down HZ).

Well, VM hosts like VMware and VirtualBox usually just return the
'native' CPUID values to guests, but can't really support stuff like
those MSRs, for all kinds of reasons.

I was just looking at this from a viewpoint of "it worked for years, and
now it broke". :)

In any case, I don't see why a bit of defensive programming would be bad
here, so I propose the following patch to revert to the 'old' way of
estimating the rate, in case reading the MPERF MSR returns zero.

Thanks!

Does this analogous patch for cd(4) and da(4) look good? I am not
completely sure if it's safe to move setting of minimum_cmd_size in
daregister().

Move TUNABLE_INT_FETCH() out of the SIM lock to avoid sleeping while
holding the lock. The fix is analogous to r220618 for ada(4).

Log:
  In r219639, SSSE3 instruction set support was backported to our gcc.
  
  Therefore, we also need to install the new tmmintrin.h header containing
  the related intrinsic functions, similar to xmmintrin.h, emmintrin.h,
  etc.

New Revision: 220631

Log:
  Add a function rdtsc32() to read lower 32 bits from TSC and discard upper
  32 bits.  Some times compiler inserts unnecessary instructions to preserve
  unused upper 32 bits even when it is casted to a 32-bit value.  It reduces
  such compiler mistakes where every cycle counts.

Log:
  Instead of trying to figure out which rxon.flags to clear, restart
  from scratch. Remove htole16() calls, rxon.chan is an uint8_t,
  ieee80211_chan2ieee() does return an ic_ieee as an int, but I heavily
  doubt a htole16() will buy us anything here.

Log:
  Work around an emulator problem where virtual CPU advertises TSC is P-state
  invariant and APERF/MPERF MSRs exist but these MSRs never tick.  When we
  calculate effective frequency from cpu_est_clockrate(), it caused panic of
  division-by-zero.  Now we test whether these MSRs actually increase to avoid
  such foot-shooting.

It only seems to make big difference in amd64, probably because 
rdtsc() is implemented differently in inline asm.

tsc_get_timecount (before):
        pushq   %rbp
        movq    %rsp, %rbp
        rdtsc
        mov     %eax, %eax
        salq    $32, %rdx
        leave
        orq     %rax, %rdx
        movl    %edx, %eax
        ret

tsc_get_timecount (after):
        pushq   %rbp
        movq    %rsp, %rbp
        rdtsc
        leave
        ret

Similar problem was also observed when it is inlined.

BTW, clang does not have this issue. :-)

Can we instead assert it is always held and fix callers that don't?  Using 
locked variables is messy and I'd rather avoid it when possible.  We already 
require the caller to hold other locks for this operation.

New Revision: 220645
URL: http://svn.freebsd.org/changeset/base/220645

Log:
  Modify the experimental NFSv4 server so that it handles
  crossing of server mount points properly. The functions
  nfsvno_fillattr() and nfsv4_fillattr() were modified to
  take the extra arguments that are the mount point, a flag
  to indicate that it is a file system root and the mounted
  on fileno. The mount point argument needs to be busy when
  nfsvno_fillattr() is called, since the vp argument is not
  locked.

Log:
  Fix the experimental NFSv4 server so that it uses VOP_PATHCONF()
  to determine if a file system supports NFSv4 ACLs. Since
  VOP_PATHCONF() must be called with a locked vnode, the function
  is called before nfsvno_fillattr() and the result is passed in
  as an extra argument.

New Revision: 220649
URL: http://svn.freebsd.org/changeset/base/220649

Log:
  Fix a couple of bad races that can occur when a cxgbe interface is taken
  down.  The ingress queue lock was unused and has been removed as part of
  these changes.
  
  - An in-flight egress update from the SGE must be handled before the
    queue that requested it is destroyed.  Wait for the update to arrive.
  
  - Interrupt handlers must stop processing rx events for a queue before
    the queue is destroyed.  Events that have not yet been processed
    should be ignored once the queue disappears.
  
  MFC after:	1 week

  update_gdt_{f,g}sbase. The functions set the flag when td == curthread,
  and sysarch is always called with curthread.

This broke several of my machines in a somewhat strange way:

After upgrading them (17) to a recent 7-STABLE (as of 2011-04-12)
I noticed that some (4) of them didn't start. All 4 didn't find
their boot device anymore. What they all got in common is:

- an Adaptec 2940 Ultra SCSI adapter
- two SCSI harddisks (da0 and da1) of various brands
- one SCSI CDROM drive (cd0)

To be exact, none of the three devices (da0, da1, cd0) were
detected at all. Other machines with a similar configuration
(2940 and da0/da1) but _without_ the CDROM drive didn't have
any problems. So I simply removed the CDROM drives on the 4
machines in question and they all booted again.

Today I decided to dig into this and after reverting(*) the
above change, they worked with the CDROM again. I have cross-
checked it 3 times. No idea what's happening here...

	-Andre

(*) To be honest, I use this patch so I had to modify only one file:

New Revision: 220657
URL: http://svn.freebsd.org/changeset/base/220657

Log:
  Some changes around hot-plug and interface power-management:
   - use ATA_SE_EXCHANGED (SError.DIAG.X) bit to detect hot-plug events when
  power-management enabled and ATA_SE_PHY_CHANGED (SError.DIAG.N) can't be
  trusted;
   - on controllers supporting staggered spin-up (SS) put unused channels
  into Listen state instead of Off. It should still save some power, but
  allow plug-in events to be detected;
   - on controllers supporting cold presence detection (CPD), when power
  management enabled, use CPD events to detect hot-plug in addition to PHY
  events.

Log:
  Fixes for firmware handling:
  - there is a local variable for sc->fw_dma, use that instead
  - OpenBSD uses 5*hz to wait for firmware to be loaded
  - in case the firmware module contains invalid data, actually release it

I do not see how allproc_lock is useful there, unless setuid(2) and
other syscalls, which change the process credentials, are protected by
the same lock. The issue there is in accounting for wrong container.
You want to avoid a race between dereferencing stale p_ucred and the
process moving to another container.

I thought the issue was just prevent destroying of process/ucred I may
need to better look at callers then if you also want to avoid
credentials changes. BTW, a global lock for that is not what I really
hope to see.

As you already hold allproc_lock the process can't be distructed, then
as I already pointed out to Tomasz, it should alright to just bump the
refcount for cred and pass down, I guess.

 ----------------------------------------
+13 April 2011. Summary of changes for version 20110413:
+
+1) ACPI CA Core Subsystem:
+
+Implemented support to execute a so-called "orphan" _REG method under the EC 
+device. This change will force the execution of a _REG method underneath the EC 
+device even if there is no corresponding operation region of type 
+EmbeddedControl. Fixes a problem seen on some machines and apparently is 
+compatible with Windows behavior. ACPICA BZ 875.
+
+Added more predefined methods that are eligible for automatic NULL package 
+element removal. This change adds another group of predefined names to the list 
+of names that can be repaired by having NULL package elements dynamically 
+removed. This group are those methods that return a single variable-length 
+package containing simple data types such as integers, buffers, strings. This 
+includes: _ALx, _BCL, _CID,_ DOD, _EDL, _FIX, _PCL, _PLD, _PMD, _PRx, _PSL, _Sx, 
+and _TZD. ACPICA BZ 914.
+
+Split and segregated all internal global lock functions to a new file, evglock.c.
+
+Updated internal address SpaceID for DataTable regions. Moved this internal space 
+id in preparation for ACPI 5.0 changes that will include some new space IDs. This 
+change should not affect user/host code.
+
+Example Code and Data Size: These are the sizes for the OS-independent acpica.lib 
+produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug version of 
+the code includes the debug output trace mechanism and has a much larger code and 
+data size.
+
+  Previous Release (VC 9.0):
+    Non-Debug Version:  89.8K Code, 23.8K Data, 113.6K Total

+
+2) iASL Compiler/Disassembler and Tools:
+
+iASL/DTC: Major update for new grammar features. Allow generic data types in 
+custom ACPI tables. Field names are now optional. Any line can be split to 
+multiple lines using the continuation char (\). Large buffers now use line-
+continuation character(s) and no colon on the continuation lines. See the grammar 
+update in the iASL compiler reference. ACPI BZ 910,911. Lin Ming, Bob Moore.
+
+iASL: Mark ASL "Return()" and the simple "Return" as "Null" return statements. 
+Since the parser stuffs a "zero" as the return value for these statements (due to 
+the underlying AML grammar), they were seen as "return with value" by the iASL 
+semantic checking. They are now seen correctly as "null" return statements.
+
+iASL: Check if a_REG declaration has a corresponding Operation Region. Adds a 
+check for each _REG to ensure that there is in fact a corresponding operation 
+region declaration in the same scope. If not, the _REG method is not very useful 
+since it probably won't be executed. ACPICA BZ 915.
+
+iASL/DTC: Finish support for expression evaluation. Added a new expression parser 
+that implements c-style operator precedence and parenthesization. ACPICA bugzilla 
+908.
+
+Disassembler/DTC: Remove support for () and <> style comments in data tables. Now 
+that DTC has full expression support, we don't want to have comment strings that 
+start with a parentheses or a less-than symbol. Now, only the standard /* and // 
+comments are supported, as well as the bracket [] comments.
+
+AcpiXtract: Fix for RSDP and dynamic SSDT extraction. These tables have "unusual" 
+headers in the acpidump file. Update the header validation to support these 
+tables. Problem introduced in previous AcpiXtract version in the change to 
+support "wrong checksum" error messages emitted by acpidump utility.
+
+iASL: Add a * option to generate all template files (as a synonym for ALL) as in 
+"iasl -T *" or "iasl -T ALL".
+
+iASL/DTC: Do not abort compiler on fatal errors. We do not want to completely 
+abort the compiler on "fatal" errors, simply should abort the current compile. 
+This allows multiple compiles with a single (possibly wildcard) compiler 
+invocation.

Log:
  MFC r220376: Allow strerror(0) and strerror_r(0, ...).
  
  Of course, strerror_r() may still fail with ERANGE.
  
  Although the POSIX specification said this could fail with EINVAL and
  doing this likely indicates invalid use of errno, most other
  implementations permitted it, various POSIX testsuites require it to
  work (matching the older sys_errlist array) and apparently some
  applications depend on it.

Log:
  MFC 219717,220363:
  - Add more details to the 'show battery' command including more raw
    capacity values, charge cycle count, temperature, and more detailed
    status.
  - Add the ability to manage the state of write caching when the battery
    back-up is missing or dead.  The current state of this field is reported
    in 'mfiutil cache ' and can be adjusted via
    'mfiutil cache  bad-bbu-write-cache '.  This
    setting should generally be disabled to avoid data loss.

  Split up watchdog and calibration callout. This allows us to use different
  timing on both and to remove some monitor mode specific hacks (which has
  no calibration).

Apr 15 12:44:33  inside kernel: da0 at ahc0 bus 0 target 0 lun 0


If I remember things correctly, the line marked XXX is where the
bad kernel stopped and spit out the panic about the missing root
fs. I am 99% sure that pass0 and pass1 could be found in both
cases, however, everything related to da0 and da1 were missing
whith the bad kernel.

Unfortunately, I have no access to these machines before monday
to create the verbose dmesgs. Also all 4 machines are in
production but I think I can figure something out next week...

Thanks,

	-Andre

  Clamp the initial advertised receive window when responding to a SYN/ACK
  to the maximum allowed window.  Growing the window too large would cause
  an underflow in the calculations in tcp_output() to decide if a window
  update should be sent which would prevent the persist timer from being
  started if data was pending and the other end of the connection advertised
  an initial window size of 0.

Log:
  Change the experimental NFS client so that it creates nfsiod
  threads in the same manner as the regular NFS client after
  r214026 was committed. This resolves the lors fixed by r214026
  and its predecessors for the regular client.

New Revision: 220686
URL: http://svn.freebsd.org/changeset/base/220686

Log:
  Move TUNABLE_INT_FETCH() out of the SIM lock to avoid sleeping while
  holding the lock. The fix is analogous to r220618 for ada(4).

Log:
  Remove the flags argument of iwn_dma_contig_alloc(), it is always set
  as BUS_DMA_NOWAIT. While here also set BUS_DMA_COHERENT.

Log:
  Rewrite DMA segment handling to be more inline with the OpenBSD code.
  Also change the m_len == 0 hack to have less code churn.

Log:
  Disable classic-style fast diversity on the AR5416 and later.
  
  Antenna diversity on the >= AR5416 is implemented differently than the
  AR5212 and previous chips. So for now, and not to confuse things, just
  disable it for now.

New Revision: 220729
URL: http://svn.freebsd.org/changeset/base/220729

Log:
  Add some new features:
  - 6000 series devices need enhanced sensitivity calibration.
  - 6000 series devices need a different setting for the shadow reg.
  - set the IWN_FLAG_HAS_11N bit if the EEPROM says the device has 11n
    support.

Forgot to mention this:
The device capability announcements are now hidden behind bootverbose.
Once the 11n bits are in this is gonna be quite spammy otherwise.

New Revision: 220732
URL: http://svn.freebsd.org/changeset/base/220732

Log:
  Add a lktype flags argument to nfscl_nget() and ncl_nget() in the
  experimental NFS client so that its nfs_lookup() function can use
  cn_lkflags in a manner analagous to the regular NFS client.

      VNET socket push back:
      try to minimize the number of places where we have to switch vnets
      and narrow down the time we stay switched.  Add assertions to the
      socket code to catch possibly unset vnets as seen in r204147.
  
      While this reduces the number of vnet recursion in some places like
      NFS, POSIX local sockets and some netgraph, .. recursions are
      impossible to fix.
  
      The current expectations are documented at the beginning of
      uipc_socket.c along with the other information there.

New Revision: 220734
URL: http://svn.freebsd.org/changeset/base/220734

Log:
  MFC r220556:
  
    If building (custom) FreeBSD images people tend to patch param.h.  In case
    this happens just before the build is started (within the same second)
    CHECK_TIME actually triggers thinking param.h is in the future (see f_Xtime,
    c_Xtime logi in find(1) sources for the details in !F_EXACTTIME case).
    Using the -mtime -0s (seconds, rather than no unit) avoids this 1s race.
