2008-01-11 08:19:03     mapping framebuffer in DirectFB fails

joachim stahlhacke (GERMANY)

Message: 49502    Hi all,

I try to run a directFB programm on a BF-548EzKit Board. I use directFB 1.1.1-release and compiled it for the blackfin without jpeg-, png-image provider and freetype.

I also build a uclinux-kernel with framebuffer support and the bf54x-lq043 driver (e.g. nano-X works fine).

After invoking a directFB Programm I get a: Could not mmap frambuffer ---> no such device error.

In directFB I found the lines:

     /* Map the framebuffer */

     dfb_fbdev->framebuffer_base = mmap( NULL, shared->fix.smem_len,

                                         PROT_READ | PROT_WRITE, MAP_SHARED,

                                         dfb_fbdev->fd, 0 );

     if (dfb_fbdev->framebuffer_base == MAP_FAILED) {

          D_PERROR( "DirectFB/FBDev: "

                    "Could not mmap the framebuffer!\n");

I then searched a little bit in the mmap-sources and found the reason for the mmap to fail in /mm/nommu.c:

        if (!file->f_op->get_unmapped_area)

             capabilities &= ~BDI_CAP_MAP_DIRECT;

and

        if (!(capabilities & BDI_CAP_MAP_DIRECT))

              return -ENODEV;          

Has anybody experiences with this stuff or can give me a hint weather it might be a problem in the driver, the kernel or in directFB(...) ?

Thanks a lot

-joachim-

Message: 49510    Joachim, I am using nano-X myself without a problem, I would really like to goto directFB soon, I believe it will be faster than the less than exciting XLib protocols that seem to cause such a slow down.

Anyhow, I have written some external test programs, and also needed to patch nano-X to get the FB to work properly.

This is the call I make:

fb_handle  = (unsigned short *)mmap(0, height * width * (bpp >> 3), PROT_READ | PROT_WRITE, MAP_FILE | MAP_PRIVATE, screenHandle, 0);

I have tried MAP_SHARED, and it always fails, so try MAP_FILE | MAP_PRIVATE, I believe I took this from the video_test program when I was working with the BF537 EZKIT, I now work with the BF548 EZKIT and the LQ043 It works pretty great.

It would be great to exchange information on a regular basis if we find anything new, since it sounds like we are both working with the display on the 548. In any case, let me know how directFB goes, and what the footprint is. I don't use any widgets library, but rather create some basic ones myself under nano-X. As I mentioned, I want to move to directFB, and possibly use wxWidgets, as there is a new port for directFB (there is also one for nano-X).

Message: 49512    Hi Joachim and Kris,

I also use the LQ043 (an equivalent in fact, but in extended temperature version), but under bf537.

I plan to use nano-X, without windows manager or widget toolkits, because everything will be done "at hand".

What you say about directFB interrest me too if it is faster than nano-X.

It is complicated to compile it and integrate it in the uClinux dist ?

Regards,

Cyril

Message: 49514    It shouldn't be too complicated, just need to add some basic patches for the configuration. I may have a go at it later on if nobody else has gotten around to it.

Message: 49519    as Kris indicated, this is merely the MAP_SHARED issue again

ive fixed it and added DirectFB-1.1.1 to the dist ... feel free to test it.  the bundled test programs seemed to run fine on my BF548-EZKIT.

Message: 49541    good news, thank you very much. I'll try as soon as my svn is working again...

Kris:

It would be fine to exchange experiences about directFB and the display. But I must admit I'm just at the very beginning...

Message: 49733    Mike:

sorry, it toolk me quite a while to start testing... I made a complete download of the toolchain, the dist, the kernel and u-boot yesterday (started from scratch). I tried to build directfb via menuconfig (build libraries), but  got a compilation error : "dlfcn.h missing". I found it in the toolchain sources and copied it (and /bits/dlfcn.h) from

toolchain/uclibc/include and

toolchain/uclibc/libc/sysdeps/linux/common/bits.

Now compilation worked and the tools are build, too.

I tried to run them on the board and got :

(*) DirectFB/Core: Single Application Core. (200-01-16 15:34)

DirectFB/core/system: No system found!

Tools/Screen: DirectFBCreate() failed!

    --> No (suitable) implementation found!

"strace" does not really help me out of this, so do you have an idea what i have done wrong (maybe the dlfcn.h files)?

Message: 49750    make sure you do `svn up` first as i originally forgot to actually commit the mmap fix ... i added the patch, but didnt apply it

dont go copying arbitrary header files for the toolchain ... if a header wasnt found, then hacking around the toolchain is rarely the solution.  dlfcn.h only works for FDPIC ELF, not FLAT.  i tested FDPIC ELF, not FLAT.  i'll check out FLAT today to see if it's possible.

i wasnt able to test it though as i dont have a BF548-EZKIT on me at the moment

Message: 49951    Building the DirectFB Lib seems to work. But I've got still a problem building the DirectFB Examples. Make breaks with an undefined reference error to 'pthread_mutex_unlock' in function direct_log_unlock. I also tried to run the dfbinfo program which was build in /staging/usr/bin and got the same error as above (No system found!). I use the latest toolchain and the dist and kernel from yesterday.  I hope you can help me out,

thanks

Message: 49977    for whatever reason, the library order on your system is incorrect ... this part:

... -ldirectfb -lfusion -lpthread -ldirect ...

should actually read:

... -ldirectfb -lfusion -ldirect -lpthread ...

which is how it is on my system right now

run this command and post the output:

grep ^Libs staging/usr/lib/pkgconfig/*.pc

DIRECTFB_LIBS='-L/home/joachims/uclinux/uclinux-dist/staging/usr/lib -ldirectfb -lfusion -lpthread -ldirect  ' in config.log and

DIRECTFB_LIBS = -L/home/joachims/uclinux/uclinux-dist/staging/usr/lib -ldirectfb -lfusion -lpthread -ldirect in the Makefile.

Thanks a lot for her help.

I made an update of my pkg-config to version 0.23 and now the order of the libs is correct. After that I just had a little Problem with the 'fonts' directory which was not build by make unless I created it by hand in uclinux-dist/user/DirectFB-examples. After that make worked fine... I wonder if this is an old problem and allready solved or not.

Yeah - I think that is my fault - it isn't fixed yet in svn. I will do something tonight.

After you created the directory by hand - did all the examples run OK? (some don't for me).

Too sad, I still have a problem with all of the examples. e.g. I get the following error message:

        (#) DirectFBError [DirectFBCreate(&dfb)]: No (suitable) implementation found!

Maybe there is still something wrong with my configuration?

Can you check what you have, and see if any differences pop out? You may need to force some of the libs, so the directfb build knows it really wants to build with that library...

sorry for bothering you again...

- now, after a 'make clean' I have to create a ' fonts'  directory in /romfs/usr/share/directfb-examples to make 'make' working.

- I checked the libs, and I forced the build of the missing ones (expat, faad2, flac, libaudio, libcurl, libid3tag, libidn, libmad, libssl, libusb, SDL_Image, SDL_mixer, SDL_net, SDL_ttf, tremor, tslib). Now I get an other error message:

(*) Direct/Thread: Running 'VT Switcher' (CRITICAL, 246)...

[  242:   0.000] --> Caught Signal 4 (at 0xd35fb4, illegal opcode) <--

Illegal Instruction

I tried strace and found the line just before this error message.

open("/proc/bus/pci/device ", O_READONLY) = -1 ENOENT (No such file or directory)

Do you have any Idea what might be the problem? Or could you post me your configuration file, so that I can try it out?
