• Hardware Platform (Jetson / GPU): Jetson Orin Nano • JetPack Version: JetPack 6.1 (r36.4.0), JetPack 6.2 (r36.4.3) • Issue Type( questions, new requirements, bugs): bug We are experiencing a significant kernel memory leak when using Argus cameras on the platform detailed above. Its rate of gro…

I ended up having to patch the kernel to correct this. Maybe Nvidia will reply but pm me your details and we can chat if you want.

hello anmelle, here’s a patch to address memory leak, please check whether you’ve below fix included. for instance, diff --git a/drivers/gpu/host1x-fence/dev.c b/drivers/gpu/host1x-fence/dev.c static int dev_file_ioctl_fence_extract(struct host1x *host1x, void __user *data) { ... @@ -172,6 +172…

Hello, Thank you for the patch. While the patch improves things, I can still see a growth of ~46 MB/hour as per plot below. Furthermore, I can still see the same leak highlighted by thekmemleak tool. [image]

Quick clarification question: as the path affects out-of-tree modules, could you confirm which modules are affected? Is it just host1x-fence.ko ?

hello anmelle, may I double check which Jetpack release version you’re now testing?

Currently it’s JetPack 6.1 (r36.4.0). Please disregard my previous post: I wasn’t replacing the right kernel module after rebuilding. It’s host1x-fence.ko rather than host1x.ko. After replacing host1x-fence.ko, I can confirm the kernel memory leak is fixed.

Hello JerryChang, is it possible to provide this patch, and future patches also, in ‘git format-patch’ format so that we can apply with ‘git am THEPATCH’ ?

hello phdm, [EDIT] is this helps? [0001-gpu-host1x-fence-Fix-fence-leak-in-fence_extract.patch|attachment] note, I’ve to delete author info to public the patch. I’ve upload another patch file to revise author as blank. please try to apply the attached patch here… 0001-gpu-host1x-fence-Fix-fenc…

Hello JerryChang, Thank you for the effort, but applying the file as is fails with : $ git am /tmp/0001-gpu-host1x-fence-Fix-fence-leak-in-fence_extract.patch Patch format detection failed. $ ‘git am’ requires the patch to contain a ‘From:’ line containing a email address, like From: <forum@nvid…

I’ve upload another patch file, please check my previous comment #12 for testing.

hello anmelle,

thanks for confirmation.
you may also apply that fix (i.e. comment #4) to JP-6.2/r36.4.3 as well.

FYI,
that patch of fence leak has check-in to rel-36 code-line,
please expect next JP-6 public release (i.e. JP-6.2.1/r36.5.0) will include that fix.
