[PATCH 0/2] TPM-CRB: Remove spurious error report when used with VFIO

Posted by Eric Auger 2 weeks ago
launching a guest with a TPM-CRB device and VFIO-PCI devices.

The CRB command buffer currently is a RAM MemoryRegion and given
its base address alignment, it causes an error report on
vfio_listener_region_add(). This series proposes to use a ram-device
region instead which helps in better assessing the dma map error
failure severity on VFIO side.

Best Regards

Eric
