Title:
GL clients never show up in VMware [VMWare: No 3D enabled (0,
Success).]
Status in Mir:
Confirmed
Status in mir package in Ubuntu:
Confirmed
Bug description:
Steps to reproduce:
* install vmware workstation player
* setup an ubuntu image with the zesty iso image for amd64
* apt install mir-demos
* run sudo miral-shell --arw-file --vt 2 -f /tmp/mir_socket
* mir_demo_client_eglplasma -m /tmp/mir_socket
The client application exits and in the terminal output you should see:
VMWare: No 3D enabled (0, Success).
That message is from the mesa vmware driver:
https://github.com/mesa3d/mesa/blob/master/src/gallium/winsys/svga/drm/vmw_screen_ioctl.c#L880
The ioctl seems to complete successfully but yields the wrong result.
The same can be experienced with miral-shell running in X11.
GL clients within X11 work. EGL on DRM seems to work - since
mir_proving_server on DRM works too.
Update: The problem seems to be related to dmabuf fds. The error
message mentioned above does not seem to stop the egl initialization.
So later in the process when mirclient receives the buffers the driver
fails to import the dmabuf fds. So maybe the interrupted
initialization leaves the egl structures in a state incapable to
perform the dmabuf fd to drm handle mapping.
