Subject: [PATCH 0/9] Fix runtime pm ref leaks
Date: Tue, 24 May 2016 18:03:27 +0200 [thread overview]
Message-ID: <cover.1464103767.git.lukas@wunner.de> (raw)
In preparation for runtime pm on muxed dual GPU laptops,
I've fixed all runtime pm ref leaks I could find in nouveau,
radeon and amdgpu.
To ease reviewing, I've pushed this series to GitHub:
https://github.com/l1k/linux/commits/drm_runpm_fixes_v1
@Alex Deucher: I do not have an AMD GPU so couldn't test this
beyond verifying that it compiles. Please double-check the patches
and test them internally at AMD. By the way, I've noticed that
nouveau takes a runtime pm ref in ->preclose and releases it in
->postclose. This is missing in radeon and amdgpu. Please check
if it is needed.
Thanks,
Lukas
