All platforms are using DRM. However, am335x and am437x are using what is called FBDEV emulation. Fbdev is an emulation layer that routes traditional fbdev calls to DRM. From a userspace perspective it appears that 335x and am437x are using fbdev even though technically they are using drm.
The reason why we are using fbdev emulation and not straight drm is due to the lack of support of drm in our graphics packages. > -----Original Message----- > From: [email protected] [mailto:meta-arago- > [email protected]] On Behalf Of Stiffler, Jacob > Sent: Friday, May 01, 2015 10:31 AM > To: Dmytriyenko, Denys > Cc: [email protected] > Subject: Re: [meta-arago] [nightly] Core TISDK 2015.04 build 2015-04-30_22- > 00-51 > > Does this mean drm is supported by all platforms, and "libdrm" can be a > platform-agnostic dependency? > > -----Original Message----- > From: Dmytriyenko, Denys > Sent: Friday, May 01, 2015 11:19 AM > To: Stiffler, Jacob > Cc: [email protected] > Subject: Re: [meta-arago] [nightly] Core TISDK 2015.04 build 2015-04-30_22- > 00-51 > > I think there's some confusion...
