r510gl implement DUP_OBJECT (fn 21) with the NVOS55 params echo: the EGL/GLX MakeCurrent wall
The guest driver dups memory/VASpace objects into the GL client at
EGL MakeCurrent time; the generic-SUCCESS default replied with an EMPTY
payload and the driver, expecting rpc_dup_object_v03_00
(NVOS55_PARAMETERS {hClient, hParent, hObject, hClientSrc, hObjectSrc,
flags, status}) echoed back, failed the call and tore the whole EGL
session down. r510 guest witness: 'RPC UNKNOWN(21) seq=0 len=60 ->
generic SUCCESS' immediately followed by the session's FREE cascade and
eglMakeCurrent -> EGL_BAD_ALLOC (0x3003); EGL device enumeration and
eglInitialize were already green (n=3 devices, NVIDIA 1.5). The handler
echoes the params with status=NV_OK (the emulation keeps no per-object
state for these classes).
