(I am not subscribed to the list, so please CC your replies to me.) Hello, I am having trouble getting my Matrox G450 to work on my pegasos2, after and while booting the console gets weird. It doubles the output with a space of 4 characters, so it's really hard to use it. The kernel I am using is 2.6.4 (gentoo/ppc-development-sources), I have also tried the 2.4 kernel and getting the same problems. my settings from #Graphics support CONFIG_FB=y CONFIG_FB_MATROX=y CONFIG_FB_MATROX_G450=y CONFIG_FB_MATROX_G100=y CONFIG_FB_MATROX_I2C=y I have also tried to use diffrent boot parameters, but with no luck. The output is just a screen filled with colorful pixels. I haven't tried to use X, I want to get my console working first. Thanks in advance /Johan Gullden |

This kind of information, or even a digicam picture of the screen, is essential in detecting the problem, and hopefully fixing it. Friendly, Sven Luther |

Hi Sven, > > The pictures are really bad.

I may be wrong though. Really? Take a look again. I can clearly see that the text is garbled all over the place. For example "Bringing eth0h0p..." should read "Bringing eth0 up...", "Setting defeflt gateway..." should read "Setting default gateway..." and so on. You will also notice that the broken characters are not randomly located. They are placed on two-char wide columns. Something like 12 valid columns, 2 broken ones, 12 valid, 2 broken, and so on, if it helps. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/ |

Read the text on the pictures, and you will see. Yeah, but this is not a problem with the setting up of the video mode, as i first thought it was, but probably either a problem with fbcon or text acceleration on matroxfb, or a problem with text encoding or something such. You don't use some strange (UTF8 for example) text encodings ? Can you try this with another graphic card ? Or maybe put the kernel online so someone else can test it with another graphic card ?

I may be wrong though. They are quite normal when using G100 in 2.4.x with weird memory chips. But it should not happen with 2.6.x which reads setup from ROM. So I have couple of questions: (1) What is pegasos? Is it i386/x86_64/alpha architecture which executes/emulates ROM BIOS, or is Matrox initialized only by matroxfb? Can you try 'video=matroxfb:init' or 'video=matroxfb:noinit' options (default value is autodetect whether card was initialized or not; using noinit on system which did not initialize matrox hardware may lock up PCI bus, so have reset button ready). (2) If 'video=matroxfb:init' alone will not help, you can try playing with g450_memory_init() function. It completely relies on PINS data, so if pins data are incorrect (like on GXT130P IBM distributed), driver will not work without manual tweaking default_pins5() with values your hardware needs. (2a) Do you use card from Matrox, or is it some 3rd party product - either onboard (from f.e. HP) or bundled with their own firmware (f.e. IBM)? Onboard devices are only in x86 systems, as in onboard solutions there is usually no EEPROM connected to the graphics chip, and so it is not possible to find PINS structure. (3) You can try 'video=matroxfb:sdram'. But I do not think that g450/g550 portion of driver honors this option - as I said, it completely relies on on pins... (4) Otherwise I have no further idea. Problem is definitely caused by wrong memory type, mctlwtst* or memmisc/memrdbk value. Best regards, Petr Vandrovec van...@vc... |

With card from Matrox? If you'll look at matroxfb_read_pins(), you'll find that driver reads framebuffer base address and enables BIOS at that address - it is solution recommended by Matrox if BIOS is disabled on device. You should probably instrument parse_bios() to make sure that it finds what one would expect. Region is uncacheable, so there should be no problem on CPU side, and on hardware side mga chips are designed to have all four memory regions overlapped, and their behavior is specced for such configurations. But if your card comes with firmware from IBM, you'll have to ask IBM. Unless their firmwares conform to memory layout Matrox itself uses. Petr |
