Someone reported a bug in the function graph tracer for MIPS. As I'm
still waiting on my USB serial for my Imagination MIPS board, I decided
to bring my Lemote Yeeloong laptop back up to the latest kernel. This
is where I noticed that the screen no longer displays anything.
I ran a bisect, which came across a staging commit that removed the
sm7xxfb driver. When I reverted it on a v3.18-rc5 kernel and booted it
on my Lemote laptop, the display worked again.
I then did a search for this commit and found that Debian reverted it
too. Seems that there's still some Debian users of this laptop. (RMS?)
What needs to be done to make this a "proper" driver? I can try to
support it, although I have no idea how it works :-)
This reverts commit dc93c85235efa5201e9a3c116bc3fbd1afc1a182.

Have you read the TODO file in this patch? If you are willing to work
on this, I'll be glad to apply it, but the reason I removed it was
because no one had done anything with it for a very long time.
It needs a maintainer / developer, otherwise I can't take this.
thanks,

i will like to help in this. Silicon Motion is still having SM712 in its product line and SM718 might also be a similar one.
now the problems (as i see) for me to help in the driver :
1) i am a newbie. though i have learnt a lot from the patches i sent , but still I am a newbie.
2) most important - I do not have the hardware. So from the TODO list dual head and 2D acceleration support will be tough without actually checking on the hardware.
thanks

For a driver like this, if you don't have the hardware, I wouldn't
recommend taking on the task of trying to fix it up and become the
maintainer, sorry.

ofcourse. that is the reason i mentioned in my mail that i do not have the hardware.
I am trying to get a SM712 based display card.if i manage to get one i will mail you again.

Hi Greg K-H,
I have spoken to Teddy Wang of Silicon Motion and he has agreed to give me a SM712 board. He will also be giving his guidance in the code. And we both will be the Maintainer of the code.
I will send you the patch to revert your commit after i have received the board from Teddy Wang and I have done my initial testing.
Just have a few questions, and I hope you can help me with them :-
1) do i need to have git server somewhere to send you pull request or i send you patches?
2) the tree on which i will be working that will be based on which tree : linux-next, staging-next or staging-testing?
I hope you will not mind if I ask for your suggestions whenever i get a doubt (which I will get many), after all i am still a newbie here.
thanks

I reverted the removal for our 3.16 branch only, as that's going into
the Debian 8 'jessie' release. It's not included in our 3.17 packages
and won't come back unless someone supports it upstream. That gives any
interested developers another couple of years to rescue it if they want
it in Debian 9 'stretch'.
