[Mesa-dev] [PATCH v3 0/3] Software rendering in EGL-DRM

[Boris BREZILLON]

Hello Giovanni,

I have recently been working on a DRM/KMS driver which does not support
OpenGL rendering (it only provides plane composition functionalities):
[1].

If I understand correctly you patch series might solve some of the
issues I am facing.

I'm trying to get wayland working with HW cursor and several planes,
the problem is that it depends on GBM to provides drm plane and drm
cursor support.

I tried to get EGL working with my DRM device and it always ask for an
atmel-hlcdc_dri.so module (I have applied this patch [2] to get to this
point).

First of all, am I mistaken in thinking this series could solve my
issue ?

If not, could you tell me on which branch (or which tag) you based
your work ?

I'm asking this because I tried to apply your patches on top of the
master branch (a few days ago), and after fixing some conflict I got a
segfault (sorry, I don't have the backtrace anymore :-(, but this was
related to negative stride value which was implying faulty memory
access).

Yesterday I tried to rebase your patches on top of last master branch
modifications, and it seems they've completely rework the gallium dri
module architecture ([3]) and know I get an 'undefined symbol:
dd_create_screen' error when mesa tries to load kms_swrast_dri.so.

Sorry if my questions seem stupid to you, but I'm new in graphic
related developments :-).

Best Regards,

Boris
