[PATCH 0/3] drm/vkms: add support for multiple overlay planes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

First of all, let me quickly introduce myself. I'm José Expósito and
I'm a hobbyist open source developer.
My contributions are usually in the kernel input/HID subsystems and
in its userspace library (libinput) as well as other projects.

I'm trying to learn more about the GPU and I found VKMS as a good
project to get started.

So, now that you have been warned about my (lack) of experience in this
subsystem, let's get into the patches.

The series adds support for multiple overlay planes by adding a new
module parameter that allows to configure the number of overlay planes
to add.

I checked that the planes are properly created using drm_info[1] and
also executed the IGT test "kms_plane" to make sure that the planes
were listed in the output.
In addition, I checked the vkms_composer and -even though I'm not sure
how to properly test it- it looks like it is already prepared to
compose an arbitrary number of planes.
Having said that, I really hope I didn't make any obvious mistakes.

I noticed that the docs say:
> For all of these, we also want to review the igt test coverage and
> make sure all relevant igt testcases work on vkms

I ran some plane related tests, but some of them were already failing
without my code, so I'd appreciate some help with this bit.

Thank you very much in advance for your time. Any suggestions to
improve this patchset or about what to work on next are very welcome.

Jose
