memcpy program failed in creating cuCtxCreate

Open amritoit opened this issue 10 years ago • 3 comments

Hi.. I have installed the gdev and kcuda in my system. I am using cuda in kernel space with nouveau driver. But when I am executing the test program memcpy it showing null deference error . I debugged it and found that gdev pointer is null inside "gdev_raw_dev_open" function in the file gdev_drv_nvdia.c . i.e &gdev_vds[minor] returned null. any help please??

What GPU are you using?

Thanks for your quick response. The GPU I am using is NVIDIA GK107 [Quadro 410]....

Just to update . The dmesg log is pasted here in this link http://pastebin.com/z0tV7LMg . Just to let you know, I have blacklisted the default kernel and installed cuda-toolkit hence it is using nvrm driver as a default driver in my machine.
