Regs, Rahaman. <TABLE CELLSPACING="0" CELLPADDING="0" WIDTH="100%"> <TR> <TD> </TD> </TR> </TABLE> ---------------------------------------------------------------------------------------------------------------- Hi, After getting short reply from one of the developer & after going through the following link <A HREF="http://dri.sourceforge.net/doc/drm_low_level.html">http://dri.sourceforge.net/doc/drm_low_level.html</A> , i understood that the XF86 calls are only being made to ensure security. But is it the only reason OR , there are other reasons too which i am not able to understand. Because from whatever code analysis i have done till now, i think if i exclude the security policy, then i can still call drmCreateContext from the DRI driver side.I need the fd for the drm device to call drmCreateContext() and i already have that fd when i opened the drm device using the Bus id which i got after XF86DRIOpenConnection (refer to mesa/src/glx/x11/glxext.c : function =>CallCreateNewScreen). Is this analysis correct? Can any one please throw some light here?

As i see when client sends this request to xserver, in response to this Xserver creates a drm context & pass it to the client.Client then sends this drm context to the 3D driver which uses this drm context to talk to the graphics h/w via drm kernel module. Now, my question is why do i need to create the drm context through xserver.As my 3D driver also links to libdrm, why can't i create the drm context from the 3D driver itself?
