Re: [uClinux-dev] Device number assignment

Hi Erwin.
I just wanted to check if I understood the whole procedure with setting up
the device driver (I'm just in the beginning of my Linux journy).
1. I create my driver (for the moment it's located in the in the bin
directory when I build the whole kernal, so I don't have to use FTP each
time I start up the board).
2. I use the mknod to create the device under /dev mkmod name c major minor
3. insmod driver
And then it should be done?
When I run insmod I noticed that I don't get the major number I dedicated
with mknod (I tried to use dynamically allocation), I got 254 instead.
Could there be anything in the way I setup the driver that causes this
problem?
You also mentioned that I could do it in the romfs instead. Do I only
create the name under the romfs/dev-library (in that case, who does it
know thr major and minor number).
Best regards,
Niklas
Hello!
The procedure of assigning major device number is quite comprehensively
described in Linux Device Drivers book, chapter 3
(http://www.linuxdriver.co.il/ldd3/)
Basically, you have 2 choices:
1) Assign major number statically. You just peek free major number and use it
in mknod and in your driver while device registration. Of course, you can
pre-create the device node in romfs (see dev.txt file in vendors directory)
which eliminates the need of executing mknod.
2) Dynamical assignment. You request in driver the major number for your
device and use it while device registration. THEN in user space you can
detect the assigned major number and execute mknod to create device node for
your device with right numbers. Here is snippet of my rc script which does
the thing ($module contains module name):
modprobe $module $* || exit 1
major=`cat /proc/devices | sed -n 's/^[[:space:]]*\([0-9]\+\)
[[:space:]]*'${module}'$/\1/p'`
mknod /dev/${device_name} c $major 0
AFAIK minor numbers are always assigned statically by device driver creator.
For very good description on the topic please see LDD3 book (chapter 3).

Re: [uClinux-dev] Re: uCLinux and RTAI
It only can run after that thread completes (and then waits to get rescheduled at a later time. I know. That's how my threaded app works. So I don't understand why you bother about real threads at all. some 50 Lines of C code will schedule your threads one after the other as part of a single application/process, all running on the same stack, without Linux interfering at all. (That is what my PicoOS does.) You only need Linux's help with the interrupts. Here you need to write device drivers (or use UIO which I don't know anything at all about), which set some bits (e.g. in a memory region the user process accesses via an mmaped file. An example for this is in the NIOSWiki). -Michael ___ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev

Michael Schnell wrote: No, it's not done like that. Linux does not provide thread-specific virtual memory mappings, except for special cases like the vsyscall/vdso page. So - even with full Linux, the __thread variables have different addresses per thread ? Yes. This does not make sense to me Because you haven't thought it through. You are allowed to take the address of a __thread variable in one thread, and access that specific instance from another thread, so long as the first thread has not terminated. as there is an MMU that would make accessing these variable on a single address possible Also doing it through the MMU would be slower. Count the TLB flushes. There are some circumstances in which the MMU version would be faster. Dynamically loaded libraries containing __thread variables do some indirection to access them, and virtual memory might reduce or eliminate the indirection. But other things would be slower. -- Jamie ___ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev

But some code looks like spaghetti that way, and then it's better to use scheduling points inside functions, rather than having to return from the whole function stack after recording local state into a state structure. Of course you can still do that without a kernel :-) For more complex real-time stuff, often you have priorities, locking between threads, and priority inheritance to avoid priority inversion. The simple event-driven loop gets complicated with priorities, when one event handler needs to interrupt another event handler in the middle.

Re: [uClinux-dev] sqlite
Hi, getting SQLite to work on uClinux is pretty straightforward. I just did for my first project for uClinux too :-) You need to use few macros to get it working though. All are documented here http://www.sqlite.org/compile.html. You can use -DSQLITE_THREADSAFE=0 to disable mutexes and all locking altogether. Use -DSQLITE_OMIT_LOAD_EXTENSION to get over the errors you posted, this option omits the entire extension loading mechanism from SQLite (no calls to dlopen, ...). There are plenty of other options to omit features that you don't use and that will help you get smaller footprint. --- Jan Ringoš, www.ringos.cz software architect, programmer - Original Message - From: nunya busness To: uclinux-dev@uclinux.org Sent: Monday, March 16, 2009 9:12 PM Subject: [uClinux-dev] sqlite This is my first project in uClinux.

The oggplay usage says -w takes a filename when really it takes a
timeout value like msec.

The fork is there so that when playing multiple tracks things don't get clagged up. Was easier doing this than tracking down all the state destruction and rectifying it. If your use is single tracks only then there is no need for the fork() call. My goal with oggplay was to take essentially the same arguments as mp3play. i.e. drop in compatible, hence the mess. PS, your patch only addresses one of the fork() calls. There is another harmless one :-) i'm aware of the ip one (-i), but i honestly dont care about oggplay. i spent 30 seconds of effort to get it working in the common case (`oggplay foo.ogg`). btw, please dont take this the wrong way. i imagine oggplay does all the crazy things you say it does, but we just wanted to validate that the tremor decoding library worked (download an ogg and listen to it on the board). so everything beyond that is cheese to us ;). -mike signature.asc Description: This is a digitally signed message part. ___ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
