Hi, I'm not sure if Yocto 2.3 has new enough version of Mesa and kernel for that. Seems that it defaults to Weston 1.11 so I'd assume no. Also I got impression that NXP versions of drivers support HW better (graphics work faster etc. maybe?). That I don't have my own experience so just relying what I've read.
But anyway thanks. Now I have something to go forward. -Teemu Keskinarkaus -----Original Message----- From: wayland-devel [mailto:wayland-devel-boun...@lists.freedesktop.org] On Behalf Of Daniel Stone Sent: 23. toukokuuta 2017 10:04 To: Keskinarkaus, Teemu Cc: wayland-devel@lists.freedesktop.org Subject: Re: Using EGL drivers in Weston without FBDev Hi Teemu, On 23 May 2017 at 05:33, Keskinarkaus, Teemu <teemu.keskinark...@crosscontrol.com> wrote: > I just ran into this although support was dropped almost a year ago. > > Since FBDEV no longer has EGL ‘hackery’ support, what is then the ‘proper’ > way to use EGL drivers? ie.

The recommended way is to use EGL on top of KMS (kernel modesetting), the combination of which is called GBM. This is what's implemented by Mesa, and also several other drivers including ARM Mali. The last time I saw NXP i.MX code for Weston, it was a fork of Weston using their own API for rendering and buffer management. I don't know if this ever got ported forward to newer versions, so you'd probably be needing to use their tree anyway. I know this isn't the advice you were hoping to get, but I would strongly recommend contacting NXP and asking them to support KMS and GBM like everyone else. The good news is that the 'Etnaviv' and imx-drm drivers inside Mesa and the mainline Linux kernel work just fine, so if you use very new versions of Mesa and the kernel, there should be no need to run NXP's fork of Weston and their EGL drivers.
