Yes. The requirement is that Weston must support that hardware. > 2.Is DRM must for weston(compositor),how to setup DRM? No, DRM is not a must. DRM and DRI2 are one of the multiple possible ways for Weston to access the hardware, but not the only one. No, I don't know any other ones. The point is that a GPU manufacturer may choose to support Wayland and Weston through other means. > 3.In order to run weston-launch,do i have to use gpu? Yes. That's the whole point of running Weston: showing something graphical. > 4.Does GPU kernel drvier consist of kernel/driver/gpu/xxxx(xxxx.ko??) and of > kernel/driver/gpu/drm/xxxx(DRM_xxxx.ko)? > 5.Does user side drvier consist of EGL/OpenGLES? EGL is required, but OpenGL ES isn't. Applications can use shared memory for raster pixels, but that's not efficient. Applications should use OpenGL ES 2 if they can. > 6.graphics architecture is > Application⇒EGL/OpenGLES/⇒libDRM⇒DRM_xxxx.ko⇒xxxx.ko⇒GPU? -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ IVI mailing list [email protected] https://lists.tizen.org/listinfo/ivi
