Subject: Page fault storms and IH ring overflow
Date: Wed, 5 Jun 2024 13:18:46 +0200 [thread overview]
Message-ID: <9ff42462-55eb-4e71-996a-498533d85a8a@amd.com> (raw)
Hi guys,
just FYI: Alex published yesterday a bunch of new firmware files:
https://gitlab.freedesktop.org/drm/firmware/-/commits/amd-staging
One major issue which should be fixed by those is that page faults can
no longer overflow the IH ring buffer on APUs and older dGPUs.
Newer dGPU with IH 6.x (Navi 3x) should redirect them to the secondary
IH ring where they can overflow as much as they want and don't cause any
more trouble.
Kudos to Sunil for looking into all of this and pushing our firmware
team to implement the necessary fixes.
Regards,
Christian.
