Hi all, The idea is to be able to use EGL Streams if we can, without requiring the compositor to add "-eglstream" to the Xwayland command line, Xwayland would automatically try EGL streams backend if it can.
To be able to use an EGL backend, we need: - The required EGL extension(s) to be supported - The required Wayland interface(s) to be available. The former is pretty easy, but the later requires to be connected to the Wayland display to query the Wayland registry. As the Wayland interfaces depend on the EGL backend being considered, we need to initialize all the backends, based on the EGL extensions available, and eventually choose which one to use based on the Wayland interfaces availability. The following patch series does that, by refactoring the existing code to have multiple EGL backends at first and be able to point to the one to use eventually. With this, if both GBM and EGL streams are available and usable, we would select GBM, but if GBM is not available or not usable, we would automatically try EGL streams, if available. And failing that, we would use SW. That makes the use of the command line "-eglstream" optional, yet if specified, it forces the EGL stream backend as before (and fallback to SW if EGL stream is not available, again, just as before). This new patch series applies on top of the previously submitted series: https://patchwork.freedesktop.org/series/43704/ And supersedes the previous patch series: https://patchwork.freedesktop.org/series/43783/ https://patchwork.freedesktop.org/series/43931/ Which will be marked as such in patchwork.
