Thanks, Sasha ------------------ original commit in Linus's tree ------------------ From 810cd4bb53456d0503cc4e7934e063835152c1b7 Mon Sep 17 00:00:00 2001 From: Alex Williamson <alex.williamson(a)redhat.com> Date: Fri, 8 Mar 2024 16:05:23 -0700 Subject: [PATCH] vfio/pci: Lock external INTx masking ops Mask operations through config space changes to DisINTx may race INTx configuration changes via ioctl. Create wrappers that add locking for paths outside of the core interrupt code. In particular, irq_type is updated holding igate, therefore testing is_intx() requires holding igate. For example clearing DisINTx from config space can otherwise race changes of the interrupt configuration. This aligns interfaces which may trigger the INTx eventfd into two camps, one side serialized by igate and the other only enabled while INTx is configured. A subsequent patch introduces synchronization for the latter flows.

When ODM configuration is dynamically changed and the OTG is on blank pattern, we will need to reprogram OPP's test pattern based on new ODM configuration. Therefore we need to lock the OTG pipe to avoid temporary corruption when we are reprogramming OPP blank patterns. [HOW] Add a new interdependent update lock implementation to lock all enabled OTG pipes even when there is no plane on the OTG for DCN32.

For example, virtio-mem currently doesn't support suspend+resume, and trying to freeze the device will always fail. Afterwards, the device will no longer respond to resize requests, because it won't get notified about config changes. Let's fix this by re-enabling the config if freezing fails.

Subsequent code would then try to access either a null pointer or an error value. The invalid dereferences were only possible with malformed userspace apps which never properly initialized the rendering contexts. Check the results of vmw_context_cotable to fix the invalid derefs.
