Hi Cédric
Subject: Re: [PATCH v1 3/7] hw/pci-host/aspeed_pcie: Drop AST2600 RC_H
root-bus remap and bus-nr property
On 1/27/26 04:23, Jamin Lin via qemu development wrote:
The original AST2600 PCIe design supported both RC_L and RC_H, using
root bus number 0 for RC_L and 0x80 for RC_H. In that model, the root
port appeared as
80:08.0 and QEMU carried a "bus-nr" property plus a config-space bus
remap to translate bus 0x80 to bus 0x00 for PCI enumeration.
Linux mainline has since dropped RC_L support and updated the RC_H
root bus
Was PCI support for the Aspeed SoC merged in mainline ?
The ASPEED PCIe RC driver has been applied to the PCIe subtree in the next
branch.
Please refer to the following links for details.
The change will be merged into the Linux mainline soon.
