Good news maybe ? With “modprobe psb no_fb=1 ignore_acpi=1″, Xorg does not freeze anymore. On the other hand, I occasionally get kernel panics (keyboard leds flashing) while waking up from standby.

thanks pabr
I’ll upgrade to 2.6.30-r2 and try to stick to what you’ve done.
thx

While trying to load psb.ko on Fedora 11 runing on IB888 Atom SBC I get a following error:

[drm:psb_do_init] *ERROR* Gatt must be 256M aligned. This is a bug.

Same thing with gentoo and same drivers built from source. If I comment out this check in source code, module loads successfully but board locks-up when starting X.

Does anybody know how to solve this issue?

For what it’s worth, I now have psb running with linux-2.6.30.2 and FC10 on the Vaio P. Earlier attempts with linux-2.6.29 failed with mysterious OOM errors. This time I used sources from psb-kernel-source_4.41.1-0ubuntu1~904um1_all.deb, with straightforward fixes.

But Xorg still hangs after a few hours: The display freezes (except the mouse pointer) and Xorg.0.log says “[mi] EQ overflowing. The server is probably stuck in an infinite loop”.

hi guys,
I finally managed to compile the psb kernel modules against a 2.6.29 kernel.
I also copied the firmware to /lib/firmware (looking at the kernel’s logs, it seems the psb kernel mod needs it at probe time).

anyway, nothing exciting, because as soon as I modprobe the psb kern mod (I actually probe the customized drm, then psb), my console (and my X) display gets screwy. everything is condensed and repeated 3 times…
nothing usable.

I even tried with the more up-to-date version from the Ubuntu Mobile team (4.41.1). exact same stuff

it seems someone posted something similar up in the thread. did anyone fix that issue?

Adam, firstly I am completely new to Linux so excuse my wet behind the ears questions. I have found your blog invaluable in a number of areas the past week or two whilst I ‘learn the ropes’ having installed Ubuntu.

Where I am still struggling, is one of your favourite subejcts; the video driver on the VAIO-P. I have followed your instructions, seen to have got the driver and packages installed operationally, however am still getting the “framebuffer” error you mention in your post.

I have entered the mem=1500MB line, also trying different figures but it makes no difference. Same error and back to VESA.

Any help or thoughts you can provide would be greatly appreciated. As for Ubuntu, I am loving it; it has really made the VAIO-P come alive after being tied down under Vista to a grunting, hard to use piece of kit.

Thank you in advance,

Gareth

In Ubuntu Jaunty on my P588E setting the kernel parameter to mem=2000MB also allows the machine to boot without framebuffer errors, and also allows the use of all of the P’s memory.

It would seem something is detecting total memory incorrectly.

Obvious but worth noting: with the mem=1500MB kernel option, the free command obviously reports only 1.5gb of memory available while running. You’re tossing out half a gig of RAM there.

Ok, last week I tried to get the psb driver work on Debian (5.0) using your sources. I was able to build the modules successfully and during boot it seems that the psb framebuffer module is getting loaded as my screens goes off for couple of seconds from ugly console and then it comes back with crisp resolution on the console while it is still booting.

However, as soon as my Xserver starts I get the following error message in my Xorg log file:

xf86MapVidMem: Could not mmap framebuffer (0×00000000, 0xdfe80000) (Cannot allocate memory)

I also tried the mem=1500M parameter as suggested by AdamW but as soon as the kernel tries to boot I get the following message:

Error 28: Selected item cannot fit into memory.

Any clues?

Hi,

I am trying to make the Poulsbo driver work on Debian system. Does anybody has any pointers on how to get started on this? Can I just convert the rpm packages to deb using alien and install them? I do realize that I will still need to compile the psb drm module for my existing kernel.

Or else if I have to build all the deb packages from the source, how do I get started? I am willing to spend some time on this but I need some direction as to how to proceed. Thanks

hey guys,
thanx adam for those packages. that’s really helpful… even though I could not get to compile them

I have the dell mini 12. it was shipped with the dell customized version of ubuntu.
reiv: glxgears gave a rate of 900…

anyway, I wanted to blast it out and to go for gentoo (I’ve been using it for 7 years)

1) I could not get to compile the kernel mod neither the xorg driver.
my kernel is a 2.6.28 with the tuxonice patches (is 2.6.29 mandatory?).
here is the error line of the compiler:
“include/linux/mmzone.h:277: error: ‘MAX_NR_ZONES’ undeclared here”

2) for the xorg driver:
”
mm_drm.c: In function ‘bufMask’:
mm_drm.c:207: error: ‘drmBO’ has no member named ‘mask’
”

do you guys have any idea for a fix?

reiv: you wrote you successfully compiled those. could you give some details on that? a quick how-to would be perfect

thanx again for your work guys and (I hope) for your answers
