Series | Add support for PCIe3 on x1e80100 | expand |
Hi qiang, In next series can you add logic in controller driver to have new ops for this x1e80100 since this hardware has smmuv3 support but currently the ops_1_9_0 ops which is being used has configuring bdf to sid table which will be not present for this devices. - Krishna Chaitanya.

Can I add a new ops which is same as ops_1_9_0 basically and only config_sid callback is removed. Or add a new flag to determine if we need to config bdf2sid map like no_l0s. Hi Mani, what do you think about this?
