Hi,


We don't usually test with piglit and igt-gpu-tools. Instead, modetest 
utility of the libdrm is used quite often (as is it the case in order to 
test this property).


We plan to port those tools on our platform before implementing this 
kind of tests, but it will require a bit more time.

An analysis is currently ongoing.


Furthermore, do you have any advice on top of documentation for 
implementing such tests ?


I was also thinking about implementing an option into modetest to ease 
the use of this drm property (support of hexadecimal values for properties).


Regards,

Raphaël
