It doesn't look like there is anyone who is intentionally avoiding review of 
the code, but in that mailing list there has not yet been any clear merge of 
the code.  Can we test this code in our kernel on the olpc-2.6 repository?  Is 
it sensible to try to merge it with our 2.6.31 source?  Is this something you 
can test for us?

I don't see any indication that this code is for VX855, neither that
this has anything to do with 3D.

I can test it out, no problem. The only issue is that this seems more
important for support of the actual 3D driver than the actual 3D
driver. Don't know how far VIA is pertaining the work on the 3D level.
IMHO, it is quite sad that they're paying an employee to get the code
merged and the person is apparently being ignored. The lack of time by
the maintainer certainly doesn't help Linux out on hardware support...

Hi,

hardware support...

As I understand it, the only use for that particular DRM code is to
enable Via's closed-source 3D blob to work.  As such, it's being
(correctly) mostly ignored by the kernel people, whose policy is not
to accept patches that merely provide hooks for closed-source modules.

There are a few attempts to develop an open-source 3D driver for Via
chips, but it's unclear which type of DRM they'll end up using.  If
they use the DRM provided by this patch, it would then make sense to
merge it.

(DRM = Direct Rendering Manager, not that other thing.)

It looks like small fixes to a standard video playback acceleration path
to me. The mails even talk about an MPEG application that prompted the
patches.

Also it seems to be a patch against the unichrome DRM driver, whereas a
separate DRM driver is needed for the Chrome9 hardware on the VX855.

Re: 3D acceleration

2009-11-28 Thread Tiago Marques
Ok... my bad.
I'm all for the GPL'd driver but if they could provide a working
driver in the mean time, the better. The best Linux 3D driver out
there is Nvidia's one, which is a blob but works. Intel has been
putting some efforts into the open source driver but it is nothing
more than a disaster right now. Each time they update the driver
something important breaks.

As far as the kernel team at the OLPC knows, what is missing to
support the VX855? The 3D driver and the DRM patches to the kernel?
From the thread it seems to me it wasn't accepted. Unless it was at a
later date.

Best regards,
Tiago

Actually it's a problem with the openchrome driver as it does not
provide 3D acceleration or Xvideo support
for the VIA VX855 chip.Although it is possible to implement it but,
need knowledge of the driver programming.

 #6147: A graphics accelerator

 3D graphics acceleration is something we provide in Gen 1.5,
 and intend on providing in future generations as well.

I have difficulty with the intent behind closing #6147 as 'fixed'.

For me, the proof of the pudding is in the eating.  F11-on-XO-1.5 
(build 46) gives me 3+ fps in glxgears.  F11-on-XO-1 (build 9) gives 
me 2- fps in glxgears.  Is that justification enough for saying that 
3D graphics acceleration is something we provide in Gen 1.5 ??

Let me suggest that #6147 not be considered closed until the day 
when a noticeable improvement in graphics acceleration can be 
demonstrated on the XO-1.5.

 I have difficulty with the intent behind closing #6147 as 'fixed'.

#6147 was attached to the hardware component, and since the hardware now has 
the feature, the ticket can be closed.  The solution satisfies the ticket 
description.

Yes, it could have been kept open and retriaged, but for what value?  Lower 
ticket numbers don't mean higher priority or anything.  The old comments in the 
ticket delay understanding by anybody new to it.

We have a new ticket #9579 for the software work for 3D acceleration feature 
support.
