[PATCH 0/7] i3c: Fix IBI race, address handling, and reconcile DAA

Posted by Adrian Hunter 1 week, 5 days ago

Hi

Patches 1-2 fix a use-after-free race in the MIPI I3C HCI driver's IBI
handling and make IBI teardown resilient to DISEC failures.

Patches 3-7 fix address management issues in the I3C core and HCI
driver that arise when Dynamic Address Assignment (DAA) does not complete
cleanly, culminating in a reconciliation step that detects and resolves
inconsistencies between assigned address slots and registered devices.

Patches are based on top of:

      [PATCH V2 0/8] i3c: Hot-Join improvements and MIPI HCI Hot-Join support
      https://lore.kernel.org/linux-i3c/20260518115520.98335-1-adrian.hunter@intel.com/T

which, in turn, applies on top of:

      [PATCH V4 00/17] i3c: mipi-i3c-hci: DMA abort, recovery and related improvements
      https://lore.kernel.org/linux-i3c/20260515162621.57719-1-adrian.hunter@intel.com/
