2014-04-08dri3: Fix dri3_open API change by adding new dri3_open_clientKeith Packard2-5/+25
Xwayland will eventually need the current client in dri3_open. Simply changing that API is not an option though as other drivers that implement DRI3 will not have a matching function signature and will crash when called. Add a new dri3_open_client function pointer and bump DRI3_SCREEN_INFO_VERSION so that drivers can be aware of the new function which will be used in preference to the old function when available.

2014-04-01dri3: Allow asynchronous implementation for dri3_openKristian Høgsberg3-16/+30
By passing the client pointer to the dri3_open implementation, we allow the clients to implement the open callback asynchronously. If the client ignore count is positive after returning from dri3_open, we assume that authentication is in progress and doesn't send the reply. The code to send the reply is moved into a helper function, which the implementation can call upon receiving its authenticaion reply.

2014-01-12Replace 'pointer' type with 'void *'Keith Packard2-5/+5
This lets us stop using the 'pointer' typedef in Xdefs.h as 'pointer' is used throughout the X server for other things, and having duplicate names generates compiler warnings. Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Eric Anholt <eric@anholt.net>

There's nothing to stop a client from sending these requests to screens without DRI3 support, and if they do, we'll crash. Let's not do that. Reviewed-by: Jasper St. Pierre <<jstpierre@mecheye.net> Signed-off-by: Adam Jackson <ajax@redhat.com>
