That's the hardest part now. There are two DRI loaders, one is AIGLX and the
other is EGL. Both loader have their own glapi.c. Currently, the AIGLX
get loaded before the DDX driver, and thus the glapi in glx will be used.
One possible solution is as below, please help to review and comment:
let the glamor egl module get loaded prior to the AIGLX And load the proper
thus the egl will create a complete and correct context. And then latter, we
_glapi_create_table_from_handle to initialize the glx's dispatch structure.
We can treat the context created by egl for glamor is the context dedicated
client, and each time when call into glamor's rendering path, force current
context and restore to previous context at returning.
Copy to KRH, I know you are the master of DRI2/AIGLX. Any suggestion here?
