STRUCT IPROC_PCIE(9)

📛 NAME 📛

okay bestie, welcome to struct iproc_pcie(9) — the page for the iProc PCIe device. That's the whole name, and honestly it's giving very important kernel-struct main character energy 💅

🌸 SYNOPSIS 🌸

here's the struct in all its glory, copied exactly so nobody comes for me:

       struct iproc_pcie {
           struct device *dev;
           enum iproc_pcie_type type;
           u16 *reg_offsets;
           void __iomem *base;
           phys_addr_t base_addr;
           struct resource mem;
           struct phy *phy;
           bool ep_is_internal;
           bool iproc_cfg_read;
           bool rej_unconfig_pf;
           bool has_apb_err_disable;
           bool fix_paxc_cap;
           bool need_ob_cfg;
           struct iproc_pcie_ob ob;
           const struct iproc_pcie_ob_map *ob_map;
           bool need_ib_cfg;
           struct iproc_pcie_ib ib;
           const struct iproc_pcie_ib_map *ib_map;
           bool need_msi_steer;
           struct iproc_msi *msi;
        };

🫶 Members 🫶

roll call time, bestie — every field gets its moment ✨

• dev — pointer to device data structure, the classic device hookup.
• type — iProc PCIe interface type, aka which flavor of interface we're dealing with.
• reg_offsets — register offsets. literally the offsets for registers 🎀
• base — PCIe host controller I/O register base.
• base_addr — PCIe host controller register base physical address.
• mem — host bridge memory window resource.
• phy — optional PHY device that controls the Serdes. optional but iconic.
• ep_is_internal — indicates an internal emulated endpoint device is connected.
• iproc_cfg_read — indicates the iProc config read function should be used.
• rej_unconfig_pf — indicates the root complex needs to detect and reject enumeration against unconfigured physical functions emulated in the ASIC. highkey important 🫶
• has_apb_err_disable — indicates the controller can be configured to prevent unsupported request from being forwarded as an APB bus error.
• fix_paxc_cap — indicates the controller has corrupted capability list in its config space registers and requires SW based fixup. not me reading “corrupted” and gasping 😭
• need_ob_cfg — indicates SW needs to configure the outbound mapping window.
• ob — outbound mapping related parameters.
• ob_map — outbound mapping related parameters specific to the controller.
• need_ib_cfg — indicates SW needs to configure the inbound mapping window.
• ib — inbound mapping related parameters.
• ib_map — outbound mapping region related parameters.
• need_msi_steer — indicates additional configuration of the iProc PCIe controller is required to steer MSI writes to external interrupt controller.
• msi — MSI data. short, sweet, slaying 💖
