Basic Information as follows:
kernel: 3.18.25 with rt patch
nvidia driver: 352.79
card: GT 710
install steps:
1、add IGNORE_PREEMPT_RT_PRESENCE=1 in kernel/conftest.sh and kernel/uvm/conftest.sh
2、compile and insmod nvidia.ko
problems:
1、Run nvidia-smi or simple cuda example program some times, then the program will hangs.
analysis info (I had already add some debug code in nvidia code):
(1) Sometimes the number of kworker threads will increase quickly and also the os will hang(system load average increases).
----1、the program enters rm_get_gpu_uuid_raw (nv.c line: 1398), but without return.
(2) Sometimes the program is in D+ status, and hangs forever.
-----1、the program enters rm_init_adapter(nv.c line: 1383), and with nv debug log (NVRM: RmInitAdapter succeeded!), but without return.
Since nv-kernel.c source code isn’t available, Pls help me!
