[Mesa-dev] Fwd: Re: [directfb-dev] First results of Mesa/DRM based DirectFB on i915 (GLES2.0 acceleration)

[Denis Oliver Kropp]

Hi,

thanks to all of you who contributed to Mesa/DRM/KMS.

Following are some benchmark results of the new DirectFB on Mesa port.

The code is checked into git.directfb.org now.


I also think I know how to map the buffers now (see my previous mails),
using intel specific ioctl (as in libkms bo_map) with the handle returned by
eglExportDRMImageMESA.

Also, via drmMode APIs the output of df_dok is visible on screen, now :)

There are still a few glitches, but we'll checkin all this today though !
