Latest microdia git and 2.6.27-rc5

[Dmitry Nezhevenko]

I've just tried to compile latest microdia git for 2.6.27-rc5 kernel, that
contains several major fixes for my laptop. Kernel config was same as for
2.6.26 one.

Here is what I get:

/tmp/microdia/microdia-v4l.c:44:1: warning: "V4L2_CID_SHARPNESS" redefined

Do I miss something?

I've tried to compile it for 2.6.27-rc6 kernel, and got the same
errors.
I was able to reduce them by modifying includes in microdia.h file :

diff microdia/microdia.h microdia.MODIF/microdia.h
31c31,34
< #include <media/v4l2-common.h>
---
> #include <linux/mm.h>
> //#include <media/v4l2-common.h>
> #include <linux/videodev.h>
> #include <media/v4l2-ioctl.h>

But, I'm stuck at this point :

It seems that, either the struct video_device from 2.6.27 kernel is
not compatible with previous versions, or my kernel config is
incorrect (I use the kernel-2.6.27-rc6 provided by mandriva cooker).
Has someone some advice ?

Hello Dmitry, Gérald

Sorry we couldn't get back to you earlier, had to get a hold of Linux
2.6.27 kernel first,
I tried out Ubuntu 8.10, Intrepid Ibex, x86_64.
Alpha 5 release to get this driver working completely

I am attaching a copy of just the driver, it has the following features
- compiles cleanly on Linux ubuntu 2.6.27-2-generic #1 SMP Thu Aug 28
17:18:43 UTC 2008 x86_64 GNU/Linux
- sysfs is removed (sorry I just didn't feel like fixing sysfs errors)
- removes hardware resolution switching patch from the HEAD branch (
skype ekiga amsn cheese all V4L2 apps work correctly with this build )
- will NOT compile on kernels < 2.6.27 (haven't had time to put "IF
kernel version < " et al)

Can we work towards a release build for inclusion in the latest distros
- Ubuntu 8.10, Intrepid Ibex
- Fedora 10/11?
- Suse ?
This is as per this groups original plans listed on this page
http://groups.google.com/group/microdia/web/the-plan

We have an option of either using DKMS or NOT using DKMS
We can use Ubuntu Build Service(debs), & suse's build service(rpms)

Also I haven't had much luck tracking the skype issues with decoding algorithms,
Someone can help me get RAW stream (not frames) from the driver easily?
Can someone more knowledgeable please document the stream format in
the pages section.
(with these two things done, I can probably track down the problem
with hardware resolution switching patch)

Neekhil

a few issues pending with this particular release are :-

Is this a kernel bug with Ubuntu or just my sloppy programming with
microdia module ?

Hello Neekhil,

thank you for your reply.
Your archive compiles fine, but doesn't work : it does not create any
device.
And, after insmod, my webcam ( 0c45:624f ) disapears from lsusb
output.

I can provide you more information if you need.

Hi Gerald

2.6.27 is released right ? can it be a problem with -rc5 that you are using ?

Have you tried it with Ubuntu Alpha 5, perhaps we'll make a new patch
this weekend

Hello,

I upgraded my kernel with latest git available yesterday ( 2.6.27-rc6-
git5 ), and now the driver send by Neekhil works.

Thanks,

[JoJo jojo]

thats great Gérald

can you try with -rc7 released last night ;-)
