Re: I need reply in Embedded FreeBSD Kernel Theme
hi sorry for being late in reply but I had some problems in the last week. I hope u still remeber what I was talking about :) @chargen Thanx for ur reply. Embedded computer systems permeate all aspects of our daily lives. Alarm clocks, coffee makers, digital watches, cell phones, and automobiles are just a few of the devices that make use of embedded systems. The design and development of such systems is unique, because the design constraints are different for each system. I supposed a new design for reducing the size of the kernel to be able to work in such an environment which has some constraints make it does not have the ability to get large memory, large storage devices or others. / as far as your document goes: "We will unload all the drivers that indicated with zeros in the module metadata file. That would make the OS to be a few of Megabytes." unload? what is the logic here? I'm sorry but what is the real gain here, // The configuration file is dependent on the kernel (which is included as a compiled kernel). If I unload these unneeded drivers, I decrease the size of the compiled kernel So it will have the ability to work in more constrained environment and that is suitable to work for Operating Systems for small chips for embedded systems. As the Internet grew, the requirements of embedded systems also began to grow in complexity. In addition to solving classic embedded systems problems, system designers were required to add connectivity for sending and receiving data or providing an automated method for software upgrades. Rather than increase the development effort, system designers have moved toward using third-party hardware and evaluating open source software. Thanx Chargen @ andrew Thanx for your reply. I appreciate your effort to download the document. Regarding the uploading of the document to that site, I am sorry for that but I tried to attach it with the email but it was refused because its size was too large. I did not send it in the text part because the text format and tables will be lost. I am sorry for that. / After a couple of quick readings, I'm not sure I correctly understand what you plan to achieve. It sounds like you are trying to achive something like hardware specific dynamic module loading (like in Solaris, for example), but then it also sounds like you are trying to build a kernel based on a generated config which somehow involves building a tiny binary hardware profile built from POST data. Are you compiling a kernel at some point rather than just generating a loader.conf for modules in order to minimise the running size? This approach will combine the two both. It will build a kernel based on a generated config which somehow involves building a tiny binary hardware profile built from POST data. It also will use hardware specific dynamic module loading because I don't have to load all the drivers for devices connected to the machine. I will use this dynamic module loading at the start-up only not at the run time because some considerations of the embedded systems for chips not being to load modules and change how to work at run time. that would make power problems. I was most confused by We will unload all the drivers that indicated with zeros in the > module metadata file. That would make the OS to be a > few of Megabytes. > Whether you are compiling a kernel for the (chosen) hardware based on a generated kernel or loader config, I don't see a sensible case in which you would ever need to "unload" any driver. /// yeah I know it is not sensible but I wrote it as a result of what I supposed before so it has no meaning. just a result to clarify what I reduced here. Thanx for ur sympathy and I will be glad to send you my next file to get ur comments about. As much fun as it is spending hours manually tweaking and testing a kernel config for each system and deciding what modules to use, I like the idea of a one time guided process based on accurately identified hardware to build an optimal kernel, so I hope that's what you're proposing. // Actually, I am deciding many time guided process based on accurately identified hardware to build an optimal kernel because I think this is more dynamic for considerations of changing the purpose of the embedded system. I mean sometimes u may need to perform deterministic operation in this boot so u do not have to load all drivers which there will be a lot of unneeded drivers of them at this boot process. I will determine the dependencies to provide optimal kernel. Thanx Andrew @ Matt Thanx for ur reply Matt. /

Just so it gets into Google: Andriy Gapon went a few rounds of debugging with me and it turns out that the problem was that the binutils port had installed a loader in /usr/local/bin/ld that was incompatible with the module system. (/usr/local/bin/ preceeds /usr/bin in my path so I can use the lpr commands from cupsd, though it's evidently a bit of a dangerous idea.) Basically if the linker you're using to compile isn't /usr/bin/ld you may have problems building kernel modules. The easiest way to detect this is to get the -v output (version number) from the linker in use and compare it against /usr/bin/ld . I was able to do that by adding LDFLAGS += -v to the Makefile in question.

I was wondering if such systems exist, and now I see one. Luckily there is enough other timers to work fine without it.

zfs panic
Hi, Since at least r208174, I've been getting the following panic every few days on my fairly heavily loaded amd64 machine: panic: _sx_xlock_hard: recursed on non-recursive sx buf_hash_table.ht_locks[i].ht_lock @ /usr/src/sys/modules/zfs/../../cddl/contrib/opensolaris/uts/c ommon/fs/zfs/arc.c:1626 The machine has 36 disks behind mfi(4), plus some SATA L2ARC. This panic is sometimes preempted by "kmem_map too small", so I apologize in advance if this is caused by memory shortage. ___ 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"

This comes from the fact that amd64 uses simple objects files (aka .o) as kernel modules and i386 uses full-blow dso. > As far as I can tell, amd64 is the only arch in the tree that uses > link_elf_obj.c, so all other arches may be affected. > > I have to admit that I'm more than a little surprised that this > problem does not affect modules that in src, but maybe that's because > I don't know all that much about FreeBSD's build infrastructure.

I think that even out-of-base modules still use the same module build infrastructure (bsd.kmod.mk). At least this is the case for cuse4bsd. > The link line that I gave was a hack.

Module link process on i386 is like this (simplified): 1) combine object files into a single object file mod.kld ld -r -o mod.kld 1.o 2.o 2) convert it to dso ld -Bshareable -d -warn-common -o mod.ko mod.kld I believe that __start/__stop symbols for sections should be automatically added at step 2 by linker.

Could you try to make a cuse4bsd build on a stock 8-stable and compare the resulting cuse4bsd.ko (i386 build) like described earlier in this thread. Or something like this: objdump -D -x cuse4bsd.ko> a.txt objdump -D -x cuse4bsd.ko> b.txt diff -u a.txt b.txt I'll have to try that on another system, all amd64 here, and rebuilding the port gives identical cuse4bsd.ko to what we already include in system. What compiler did you bundle with the PCBSD 8.1 RC1 and how did you build the cuse4bsd ports module? Did you use something like clang? The system is just regular FreeBSD 8.1-RC1, no clang or other funky make options. The port was built with in a chroot environment with the stock FreeBSD 8.1-RC1 loaded in it. I haven't checked too much yet, but it appears that like Andriy is reporting that it's not a problem for everyone. When booting PCBSD 8.1 RC1 you will see warnings from the webcamd rc.d. --HPS Yea, i see the error messages here as well, but only on my laptop.

It looks to me like i386 uses kern/link_elf.c as its linker, while amd64 uses kern/link_elf_obj.c. link_elf.c can only find the sections containing the sysinits(and some related things) via the magic symbols. link_elf_obj.c seems to understand ELF objects much better and doesn't need those symbols to be present. It just looks up the section that contains the sysinits directly via the ELF metadata that is already present. As far as I can tell, amd64 is the only arch in the tree that uses link_elf_obj.c, so all other arches may be affected. I have to admit that I'm more than a little surprised that this problem does not affect modules that in src, but maybe that's because I don't know all that much about FreeBSD's build infrastructure. Are the src modules being linked with a linker script that is not being used for out-of-src modules? Are the people affected by this not using the base compiler to build ports?(I see that this affects PC-BSD as well, and I'd be a little surprised to learn that it wasn't using the base compiler).

Re: panic during boot on 8.0-RELEASE
I was afraid someone would say that, because it's been very difficult to reproduce the issue. Happens maybe 1 out of every 8 reboots. I'll give it a look tomorrow and see what I can find. Just to be clear, I should send you the output of the "where" command in ddb?
