pci/pcie Linux subsystem on new ARM platform

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I will have to work with a board (SoC) with an ARM926EJ-S and several
peripherals including a PCIe core that can act either as RC or EP

I have to run on it Linux Kernel 2.6.19 or higher and I can start from
a porting done for another similar board with the same ARM (but
without PCIe)

Unfortunately at the moment I have not the board yet and in the
meanwhile I am doing some study and analysis activity. In the case of
PCIe RC mode, I am wondering which activities I will have to do on
Linux internals and PCI/PCIe Linux subsystem, in particular on the
PCIe port driver (pcieport-driver in linux/drivers/pci/pcie). I can't
understand if it is suitable for any Root Complex device or I will
have to write a specific driver. In my case the PCIe Root Complex is
delivered from Synopsys and is not a typical Intel PCI Express port
that can be find on a normal PC

any suggestions / indication ?

thank you very much

Stefano
