Thanks for the info Eric. So when wayland is removed from DISTRO_FEATURES, QT uses eglfs QPA and SGX DDK UM uses libpvrDRMWSEGL.so: EGLFS (Raw), then why hard coded dependency on wayland ?
Why to package libraries in target rootfs if they are not needed ? regards Ankur On Fri, Aug 18, 2017 at 4:33 AM, Ruei, Eric <[email protected]> wrote: > Hi, Denys: > > Yes and yes, we do need the wayland libraries to be present at the target > file system because they are required by the SGX DDM UM binaries. > The SGX DDK UM supports the following three (EGL) window systems and > auto-detect which one should be used. > > libpvrDRMWSEGL.so: EGLFS (Raw) > libpvrGBMWSEGL.so: Wayland-Server, DRM owner such as kmscube, or QT QPA > EGLFS_KMS. > libpvrws_WAYLAND.so: Wayland Client > > Best regards, > > Eric > > -----Original Message----- > From: Dmytriyenko, Denys > Sent: Thursday, August 17, 2017 12:14 PM > To: Ruei, Eric > Cc: Ankur Tyagi; [email protected]; R, Karthik > Subject: Re: [meta-ti] ti-sgx-ddk-um_1.14.3699939: check for wayland in > DISTRO_FEATURES > > Thanks, Eric, > > As I was suspecting, wayland libs are required to be present for SGX to > work even in no-Wayland mode.
