Thanks for reporting. It's a bit strange that this commit shows up, 
because there's nothing that should produce a memory leak.

Could you please double-check that 3fb91f56aea4 ("drm/udl: Retrieve USB 
device from struct drm_device.dev") works correctly and that 
823efa922102 ("drm/cma-helper: Remove empty drm_gem_cma_prime_vunmap()") 
is broken?

For one of the broken commits, could you please send us the output of

   dmesg | grep -i drm

after most of the memory got leaked?

Best regards
Thomas

Hi Eli,

have you already tried using kmemleak?

This sounds like a leak of memory allocated using kmalloc(), so kmemleak 
should be able to catch it.

Regards,
Christian.

I have an idea what happens here. When the refcount is 0 in kmap, a new 
page mapping for the BO is being established. But VRAM helpers unmap the 
previous pages only on BO moves or frees; not in kunmap. So the old 
mapping might still be around. I'll send out a test patch later today.

Best regards
Thomas

Here's the patch against the latest DRM tree. v5.11-rc3 should work as well.

I was able to reproduce the memory leak locally and found that the patch 
fixes it. Please give it a try.

From e8462600662621db47bccf8174bf683513aa7102 Mon Sep 17 00:00:00 2001

Subject: [PATCH] drm/vram-helper: Reuse existing page mappings in vmap

For performance, BO page mappings can stay in place even if the
map counter has returned to 0. In these cases, the existing page
mapping has to be reused by the next vmap operation. Otherwise
a new mapping would be installed and the old mapping's pages leak.

Fix the issue by reusing existing page mappings for vmap operations.

OK, great. I'll prepare the real patch soon. Can I add your Reported-by 
and Tested-by tags?

Best regards

Feel free to add an Acked-by from my side as well.

Done, thanks. I sent out the patch. If no one complains, I'll merge it 
on Wednesday or so.

As long as you don't have any kernel parameters to enable it I think you 
need to do "echo scan > /sys/kernel/debug/kmemleak" to start a scan.

The result can then be queried using "cat /sys/kernel/debug/kmemleak".

Regards,
Christian.
