Describe the bug
leak.zip
please see the reproduce code attached.
I built the kernel myself with CONFIG_DEBUG_KMEMLEAK=y
the reproduce code is simply cudaHostAlloc a large area of memory and copy some random data into GPU memory.
after the program finishes, do
echo 'scan' > /sys/kernel/debug/kmemleak && cat /sys/kernel/debug/kmemleak
and you will got some leak info. please see attached file.
sometimes, maybe need some time. e.g 2-3min to get the kmemleak info after program finished which I don't know why.
kmemleak.log
