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.

IMO it is better to add a new ops even though it duplictes the callbacks. Because the newer platforms are not going to need this bdf2sid map anyway. But if we add a flag to determine that, then the check will become, if (pcie->cfg->ops->config_sid && !pcie->cfg->smmuv3) ... And this doesn't look good as both conditions are false for X1E80100 i.e., it doesn't need bdf2sid mapping and it is also a SMMUv3 platform. Moreover having two checks here makes it confusing also. So let's use a new callback. But please mention the IP revision in comments as like other ops. - Mani > Thanks, > Qiang > > > > - Krishna Chaitanya. > > > > On 9/13/2024 2:07 PM, Qiang Yu wrote: > > > This series add support for PCIe3 on x1e80100. > > > > > > PCIe3 needs additional set of clocks, regulators and new set of PCIe QMP > > > PHY configuration compare other PCIe instances on x1e80100.
