Message-ID: <CAD6G_RT0S43BrOeXxJ6d3p1ALbXkGumZCSPBaK1Bz=2pX3hHYQ@mail.gmail.com> Date: Tue, 3 Dec 2013 16:54:43 +0530 From: Jagan Teki <jagannadh.teki@...il.com> To: bhelgaas@...gle.com, linux-pci@...r.kernel.org, linux-kernel@...r.kernel.org Subject: Need help on Linux PCIe Hi, I have few question on Linux PCIe subsystem, I am trying to understand the PCIe on ARM platform. 1. Compared to PCI, PCIe have an extra port functionalists/services which is implemented drivers/pci/pcie/* is it true? 2. PCIe root complex is same as Host controller drivers in linux drivers/host/* 3. As individual endpoint drivers are registered to pci_core as pci_driver_register, then what is the common call for registering individual HC driver to pci-core? 4. Can you list-down the basic and advanced functionalists supported by HC driver in PCIe? 5. The PCIe port bus driver is common core? means no need to change w.r.t SOC? Request for your comments. -- Thanks, Jagan. -------- Jagannadha Sutradharudu Teki, E: jagannadh.teki@...il.com, P: +91-9676773388 Engineer - System Software Hacker U-boot - SPI Custodian and Zynq APSOC Ln: http://www.linkedin.com/in/jaganteki -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
