Thank you for the information. Yes I have a AMD GPU, It is a

already discussed about this with Alex Deuscher and he said that
I will be fine with Intel HD 620 and I can carry on with the project.

If you don't mind can you please let me know if i am on the right

Yeah, that should indeed work from the hardware side.

But it could be a problem for mentoring you since we are obviously
interested in improving the VA-API state tracker for AMD hardware.


Does this mean I cannot work on this project?


Well it depends. It means that you won't test with AMD hardware. So if 
you mentor works for AMD and doesn't has the Intel stack available it 
could get really tricky to reproduce and test things.


On the other hand you could ask if one of the Intel guys wants to mentor 
you.


Will it be okay, If I write a proposal using the current hardware and 
once the proposal get selected, I could buy the required hardware.


That could work, but I'm not sure if that fits the requirements for a 
proposal from Google.



Is it possible to write a proposal without the hardware?

It would be really kind of you, if you could let me know any other 
project that is compatible with my hardware.


 I was also looking into the project "Unit Performance tests for VA-API".

Will this be a suitable fit with my hardware.


Same problem with that one.

Christian.






Thank you very much for your time

P.S:- Sorry for the starting a new thread with the last mail. I
am new to mailing list. I will see to that I do not repeat the
same mistake.


Well starting a new thread is not much of an issue, but you could
at least remove the digest mail body :)

Welcome! From the page:

https://www.x.org/wiki/SummerOfCodeIdeas/

Might try and ping Christian König. Do you have an AMD GPU?

Hello Everyone,

I am Naveen a Junior year computer science undergrad from India. I 
really apologize for disturbing you all again. But I have been going 
through the available projects for the XorgEVoC program and the 
project *Piglit for VA-API *caught my attention. I have mailed last 
week looking out for mentors for the project, but unfortunately this 
email did not receive attention due to the busy schedule at Xorg I guess.


I have been working on the project since the last time I mailed asking 
for directions. As Alex mentioned in his reply, I have read through 
the piglit documentation and am now sufficiently familiar with piglit.


Things that I have done until now:-

 1. Read through the Piglit documentation (Capable of understanding
and writing small tests using piglit)
 2. Compiled gstreamer, and also set up the gst-uninstalled environment.
 3. Understood about the architecture of gstreamer.
 4. Currently reading about VA-API.
 5. Planning to implement a simple VA-API app to better understand the
type of tests I need to write for VA-API


I am comfortable with both C and Python and given the skill set I am 
confident of accomplishing the project. I would thus like to discuss 
the details and deliverable of the project with my potential mentor 
and would like to know how I can proceed with the project.


Since no potential mentor was mentioned in the Idea's Page, it would 
be really kind of someone if they are willing to be a mentor for the 
project. I can assure you that I will put the best of my efforts and 
dedication into the project and will see that the project is completed.


Thank you for your valuable time.
