Hello,
We're curious if anyone else has figured out NXP Layerscape Xen support to get
at least basic domains launching with minimal IO support?
Started a recent discussion on it here:
https://community.nxp.com/t5/Layerscape/How-to-determine-LS1088A-SMMU-Masters-and-Stream-IDs/m-p/2072157#M15560
We're guessing some of the NXP specific chip/interconnect designs in Layerscape
were carried over from the QORIQ PowerPC P/T series. Maybe some clues in that
Topaz hypervisor code? https://github.com/nxp-qoriq-yocto-sdk/hypervisor
Regards,
Matt
