[PATCH v2 0/5] uvesafb: a general description

[Michal Januszewski]

uvesafb is a generic driver for VBE2+ compliant video cards; an enhanced
version of vesafb and a direct successor of vesafb-tng [1].

This is the second version of this patch, and it incorporates all fixes
and cleanups suggested on the lkml.  My thanks to everyone who took
their time to review the first version.

uvesafb uses a userspace helper application (v86d, [2]) to run the x86
Video BIOS code.  This makes it possible to include in uvesafb all the
standard features (refresh rate control, video mode changes etc) that
are missing from vesafb without resorting to ugly hacks such as the ones
used in [1].  The current implementation of v86d can use either LRMI or
x86emu to run the BIOS code and supports both x86 and x86_64.

Hi Michal,

I've just tested uvesafb on my workstation ( which has a really old 
GeForce2 MX 400 Nvidia card ) and it didn't worked here.

If I remember right vesafb-ntg worked here and vesafb works for sure :)

Here the error from dmesg :

....


[   37.397298] uvesafb: Getting VBE info block failed (eax=0x4f00, err=-3)

[   37.397411] uvesafb: probe of uvesafb.0 failed with error -22


....

Here some infos I got with read-edid[1] tool:

Got it to work today with an 2.6.22-rc6-git4 kernel build-in and as 
module and I like it really . good work.

For some reason 2.6.22-rc6 didn't worked here it may have some bug with 
my harware or something ( anyway 2.6.22-rc6-git4 is just fine )

Dmesg from working kernel attached.

Gabriel C

Re: [PATCH v2 0/5] uvesafb: a general description

[-- Attachment #1.1: Type: text/plain, Size: 1835 bytes --]

I applied
http://dev.gentoo.org/~spock/projects/uvesafb/archive/uvesafb-0.1-rc2-2.6.22-rc6.patchto
2.6.22-rc6-mm1... everything seems to be working properly. However, in dmesg
I did notice the following message:

uvesafb: message too long (9872), can't execute task
uvesafb: VBE get state call failed (eax=0x4f04, err=-7)

The messages seem to get generated when I switch VTs. Just thought I would
let you know. If there is anything else I can do to help let me know.

It looks like the VBE hardware state buffer for your video card is
larger than the 4k currently supported by connector.  The problem should
be easily fixed by setting CONNECTOR_MAX_MSG_SIZE in include/linux/connector.h
to e.g. 16k.  I've already updated the patch on my website, so next time
you download it, the error messages should be gone.

Best regards,
Michal
