Even more, I argue that we shall not rely on compiler for this at all. Ideally, we should be able to build FreeBSD using the stock compilers without local modifications. Thus relying on the symbols defined by compiler, and not the source is the thing to avoid and consistently remove. We must do this to be able to use third-party tooldchain for FreeBSD builds. That said, why not define __FreeBSD_kernel as equal to __FreeBSD_version ? And then make more strong wording about other systems that use the macro, e.g. remove 'may' from the kFreeBSD example. Also, please remove the smile from comment. Ok. New patch attached. And the last, question, why not do #ifndef __FreeBSD_kernel__ #define __FreeBSD_kernel__ __FreeBSD_version #endif ? #undef is too big tools tool apply there, IMO. #ifndef is too big to apply here, IMO :-). __FreeBSD_kernel__ is in the implementation namespace, so any previous definition of it is a bug. The #ifndef breaks the warning for this bug. FreeBSD does not need it at all. There are some implementations that use FreeBSD kernel, and which could potentially benefit from providing its own value for __FreeBSD_kernel. I was only tried to be nice for the out-of-tree implementations, it boils down to kFreeBSD project preferences. And why not use FreeBSD style? In KNF, the fields are separated by tabs, not spaces. In FreeBSD style, trailing underscores are not used for names in the implementation namespace, since they have no effect on namespaces. The name __FreeBSD_version is an example of this. Does existing practice require using the name with the trailing underscores? pgpM8lL9ZnvAT.pgp Description: PGP signature

No. It was designed to be inexpensive on purpose. :)
hmmm
unfortunately I don't have a chance to test it until monday
(probably one could see if the ping times change by modifying
the value of kern.random.sys.harvest.* ).
But in the code i see the following:
- the harvest routine is this:
void
random_harvest(void *entropy, u_int count, u_int bits, u_int frac,
enum esource origin)
{
if (reap_func)
(*reap_func)(get_cyclecount(), entropy, count, bits, frac,
origin);
}
- the reap_func seems to be bound to
dev/random/randomdev_soft.c::random_harvest_internal()
which internally uses a spinlock and then moves entries between
two lists.
I am concerned that the get_cyclecount() might end up querying an
expensive device (is it using kern.timecounter.hardware ?)
On modern x86 it just does rdtsc().
So between the indirect function call, spinlock, list manipulation
and the cyclecounter i wouldn't be surprised it the whole thing
takes a microsecond or so.
I suspect it is not quite that expensive.
Anyways, on monday i'll know better. in the meantime, if someone
wants to give it a try... in our tests between two machines and
ixgbe (10G) interfaces, an unmodified 9.0 kernel has a median ping
time of 30us with slow pings (say -i 0.01 or larger) and 17us with
a ping -f .
Did you time it with harvest.interrupt disabled?

But to continue about the locks... I have this idea to re-implement SCHEDULER_STOPPED as some more general check that could be abstractly denoted as LOCKING_POLICY_CHECK(context). Where the context could be defined by flags like normal, in-panic, in-debugger, etc. And the locking policies could be: normal, bypass, warn, panic, etc. However, I am not sure if this could be useful (and doable properly) in practice. I am just concerned with the interaction between the debugger and the locks. It still seems to me inconsistent that we are going with SCHEDULER_STOPPED for panic, but we are continuing to use if (!kdb_active) around some locks that could be problematic under kdb (e.g. in USB). In my opinion the amount of code shared between normal context and kdb context is about the same as amount of code shared between normal context and panic context. But I haven't really quantified those. I think you need to keep the 'kill' case in mind. In that case you don't want to ignore locks, but the code is carefully written to use try locks instead (or should be). -- John Baldwin ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Using unmodified ping (which has 1us resolution on the reports),
there is no measurable difference irrespective

kern.random.sys.harvest.interrupt and kern.timecounter.hardware.
Have tried to set hw mitigation to 0 on the NIC (ixgbe on both
sides) but there is no visible effect either.
However I don't trust my measurements because i cannot explain them.
Response times have a min of 20us (about 50 out of 5000 samples)
and a median of 27us, and i really don't understand if the low
readings are real or the result of some races.
Ping does a gettimeofday() for the initial timestamp, and relies
on in-kernel timestamp for the response.

Re: [PATCH] Detect GNU/kFreeBSD in user-visible kernel headers
(replying with Debian hat this time) 2011/11/21 Kostik Belousov kostik...@gmail.com: There are some implementations that use FreeBSD kernel, and which could potentially benefit from providing its own value for __FreeBSD_kernel. Actually, we wouldn't be able to provide a different value for the macro (whatever its name). Our compiler simply doesn't know which version of the kernel it is building for. Only the headers do, but if we define it in the headers we'd just use the FreeBSD definitions. Our compiler defines __FreeBSD_kernel__ as an empty macro, I don't expect this will change because unlike with FreeBSD, on Debian there are strong technical limitations to making it a number. If __FreeBSD_kernel__ is to be defined in FreeBSD land, may I suggest that it is defined as an empty macro as well? This covers the vast majority of cases (e.g. like the ones in my initial patch which started this discussion), and it doesn't preclude the possibility that this macro becomes a number without breaking backward compatibility. OTOH once you define it as a number, it becomes relevant whether you did it with #ifndef or with #undef, and so you have to commit to it. Just to make it clear: It's no problem to me if it's defined as a number, but it doesn't help much either. At least from Debian POV it's not worth making a big argument about. It could be a good idea from FreeBSD POV, but please only do this if it's useful to FreeBSD. -- Robert Millan ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Not laying them out on disk is extremely fragile: the installer needs to know tons of tiny details about the partition schemes (alignment constraints, partition numbering/lettering, available space after the header, the list is very long) or it will break. One simple example is that whether a partition is ad0s1 or ad0s3 depends on its order on the disk (or in the partition table anyway). If I have an ad0s2 and s3, and delete the s2, should the new partition be s2 or s4? That depends on a lot of things the installer can't easily know about, and that even if it could, simulating which would be dangerous. -Nathan ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

loader crash / BTX halted on 9.0-RC2 DVD with AMD pseudo-RAID
This weekend I downloaded the Freebsd 9.0 RC2 amd64 ISO image and burned it to a DVD. I have a computer that currently runs Windows 7 but I plan to install FreeBSD on it in the near future so I booted it up from the DVD to check the hardware/driver status. Much to my dismay, the boot loader crashed right away (register dump followed by BTX halted) and the computer immediately rebooted. I took a video with my phone so I could capture the crash message, screenshot here: http://picpaste.com/pics/BTXcrash.1321899682.jpg I then tried tweaking a few BIOS settings and found that turning off the built-in pseudo-RAID allowed the DVD to boot normally. I changed the SATA type from RAID to AHCI. Fortunately I plan to use the controller in AHCI mode for the FreeBSD installation so this won't end up being a problem for me, but I still thought it was worth reporting. The system in question has a Foxconn A7GM-S motherboard with AMD 780G (NB) and AMD SB700 chipsets. I have a two-disk mirror for the Windows installation which is why I had RAID mode enabled in the first place. In case jhb^H^H^Hsomeone is interested, below is the output from dmesg and pciconf -lv once I booted up in AHCI mode. Let me know if any additional information or tests would be helpful. Thanks!

Re: 9.0-RC2 - bsdinstall miscount of remaining diskspace after partition deletion.

Reproducable as shown below. Workaround: if you delete a partition that is not the last partition that was created, delete all partitions created after that partition before continuing. Order does not seem to be important. The results are similar with other hard drive sizes, with the i386 or amd64 distributions, and with either 9.0-RC2 or 9.0-RC1 (I did not go back and check install discs prior to RC1) Reproducing the miscount: A 114 GB drive is used for this example: Select Manual Partitioning Perform the first Create on the drive and select GPT Creating the first partition: Add Partition size shows 114GB Change size to 4GB, set mountpoint to / and tab to OK (agree to the boot partition creation) Create a second partition: Add Partition size shows 110GB Adjust size to 10GB, set mountpoint to /usr and tab to OK Create a third partition: Add Partition size shows 100GB Adjust size to 20GB, set mountpoint to /var, and tab to OK Create a 4th partition: size shows 80GB remaining Adjust size to 40GB, set mountpoint to /data, and tab to OK. There is 40 GB remaining on the drive. Now change the size of /var. First, delete the currently configured /var partition. In the Partition Editor, adding up all the lines on the screen shows 54GB (plus a 64K boot) as allocated, so there should now be 60GB remaining. But the deleted /var space has not been added back into the total. Select Create again: Add Partition size shows 40GB Adjust size to 30GB, set mountpoint as /var, tab to OK A subsequent Create will show that 20GB is remaining, rather than the actual remaining 30GB. Selecting any size 20GB or larger for /home will give you a 20GB partition, and then an additional create will show the 10GB. This isn't a bug. The partitions are laid out on disk already, and, because you deleted one in the middle, the largest *contiguous* block of free space is 20GB, which is what is shown and the maximum it is possible to create. That's why you can make one 20 GB partition and one 10 GB partition, but not a single 30 GB one. Except that this is not intuitive. If I'm laying out a disk and haven't committed the changes yet, it should be possible to do things like resize an existing partition, or have the installer realize that if you delete one partition the other partitions that are pending should just move up to maximize free space automatically. I ran into this when first trying the new installer last week where you could not modify a pending partition's size which I found non-intuitive. -- John Baldwin ___ Issue is not just because of deleting a partition in the middle, but also because the installer doesn't use up 100% of the remaining disk space... I'm doing an install onto a 232GB drive now. Deleted all partitions, and created the following: ada0p1 64KB freebsd-boot ada0p2 10GB freebsd-ufs / ada0p3 1GB freebsd-swap none When I go to create 'p4' it automatically fills the disk space to 221GB, so now I have: ada0p4 221GB freebsd-ufs /data ..BUT I can still create 'p5' with a size of 907MB! Workaround is to delete 'p4' and hit 'Create' but for size instead of accepting default of '221GB' I input '321GB' [well over the physical disk size] - It creates 'p5' with size 221GB and now when I go to create 'p5' I get the expected 'No free space left on device'. Both times the installer showed 221GB for /data, but one time it still had 907MB left to create a fifth partition - So it rounds down the 221.9GB to 221GB giving a false impression the disk is 100% full. and yes, when I delete 'p2' and my 221GB 'p4', I can create another partition of 221GB [which is now p2] and then create another 10GB partition which becomes p4. The installer should move swap to p2 and allow me to recreate p3 with size of 331GB instead of this result: ada0p1 64kB freebsd-boot ada0p3 1GB freebsd-swap ada0p2 221GB freebsd-ufs /data ada0p4 10GB freebsd-ufs / How did p2 become 221GB when originally it was only 10GB? Seems nothing is written to disk at this point and the installer should have dynamically moved p3 into p2, and allowed to use the remaining continous disk space for p3 of 331GB [after all, it moved 221GB from p4 to p2 without a problem]. ]Peter[ There are more advanced user installer issues which I'm documenting. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to

9.0-RC2 - bsdinstall overwrites /etc/fstab and spams /etc/rc.conf after edits in shell
Fresh install of 9.0RC2. Which comes first the, installer writing config files, or user using live shell to write custom config files? On the Final Configuration' screen I have the option to change several options like hostname/root password/network/etc.etc and final option is: Open a shell in the new system I used that option to create /etc/fstab with /dev/gpt/label for my partitions. After I reboot, my 'fstab' changes were overwritten with the installer /dev/ada0p# devices. Another file I tested is '/etc/rc.conf' - it just gets appended and the 'hostname=' entry is added on the very first line, so my entries stayed in the middle. I understand Open a shell in the new system is with the config files already written and are 'editable' but that is not the case. What else is touched in that final 'Exit' that will overwrite changes made in 'shell' ? How about adding that option into the last 'Complete' dialog where the configs are all written and are safe to edit and have three options: Reboot LiveCD Open a shell in the new system ? ]Peter[ Just a complain...errr...tester. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

/usr/home vs /home
Hi, In the old days home was typically a separate partition that was mounted on /home. If you didn't have a partition the installer would create /usr/home and symlink /home to it. The root was also typically an independent partition, so it made sense not to clutter it up with home directories. Now that the default behavior is to use one big partition, the installer defaults to /usr/home + symlink. I've always liked the more succinct /home and was wondering if there is any reason why not to delete the symlink and move home to / to mimic the old many partition style? thanks, dave c ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Heads Up: NFS server will now use LK_SHARED vnode locks
Hi, I have just committed r227809 to head/current which enables the new/default NFS server's use of shared vnode locks for Read, Readdir, Readlink, Getattr and Access. Although it is hoped that this will improve performance for these operations when multiple ones are performed concurrently on the same file/vnode, I thought I should give a heads up. Why? Well it is conceivable that this may have negative issues that I haven't seen in testing along the lines of overloading a server, due to the lack of serialization of the above RPCs for the same file/vnode. If anyone encounters problems with their NFS server after upgrading to post-r227809, please email and let me know. rick ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Re: rc.conf changes IPV6
Your right Doug, didn't bother taking box down after changing to new format, it works as expected, ignoring duplicate aliases regardless of protocal. I've regrouped my configs into interfaces instead of protocals now for the change so ipv4/6 aliases can be seen together without making mistakes. Definately would be nice to see ipv6_addrs_ifname added.

Re: /usr/home vs /home
Am Mon, 21 Nov 2011 13:15:36 -1000 schrieb David Cornejo d...@dogwood.com: I've always liked the more succinct /home and was wondering if there is any reason why not to delete the symlink and move home to / to mimic the old many partition style? Hi David, I like the idea of having /usr/home better, because if you don't want to have a separate partition for homes, you would at least have a huge partition (/usr) and won't run out of space quickly. If you create /home, you'll assign the rootfs space to users without a home partitions and rootfs is typically small. FreeBSD is totally fine with /home mountpoint. It won't work differently. I consider the installer procedure as a quick way to install FreeBSD. It is for people who want to try something. And you don't want to have all these help! my rootfs is full! support questions and explain the same thing over and over again. I think, I'm not alone when I say that I prepare the disks myself instead of using the installer. I don't even know if the new installer will be capable of installing FreeBSD like I have it installed now. -- Martin signature.asc Description: PGP signature
