These network cards offer support for high-speed Ethernet and RDMA networking, with speeds of up to 200Gbps. The Ethernet functionality is implemented by two modules. One is a PCI driver(xsc_pci), which provides PCIe configuration, CMDQ service (communication with firmware), interrupt handling, hardware resource management, and other services, while offering common interfaces for Ethernet and future InfiniBand drivers to utilize hardware resources. The other is an Ethernet driver(xsc_eth), which handles Ethernet interface configuration and data transmission/reception. - Patches 1-7 implement the PCI driver - Patches 8-14 implement the Ethernet driver This submission is the first phase, which includes the PF-based Ethernet transmit and receive functionality. Once this is merged, we will submit additional patches to implement support for other features, such as SR-IOV, ethtool support, and a new RDMA driver. Changes v3->v4: Link to v3: https://lore.kernel.org/netdev/20250115102242.3541496-1-tianx@yunsilicon.com/ 1. pci_ioremap_bar returns a negative value in pci_init. 2. Adjust the declaration order to follow the reverse xmastree rule. 3. Split lines that exceed 80 columns. 4. Use XSC_SET_FIELD and XSC_GET_FIELD instead of bitfields. - for Simon Horman 5. Use big-endian consistently in cmds 6. Add comments for sem and rsv0. 7. Change mode to enum in xsc_cmd, and rename bitmask to cmd_entry_mask. 8. Remove unnecessary header files such as kernel.h and init.h. 9. Add the xsc prefix to function names. 10. Return ENOSPC if alloc_ent fails. 11. Adjust the position of free_cmd. 12. Separate different categories of #include statements with blank lines. 13. Use status instead of admin_status xsc_event_set_port_admin_status_mbox_in - for Przemek Kitszel Changes v2->v3: Link to v2: https://lore.kernel.org/netdev/20241230101513.3836531-1-tianx@yunsilicon.com/ 1. Use auxiliary bus for ethernet functionality. - Leon Romanovsky comments 2. Remove netdev from struct xsc_core_device, as it can be accessed via eth_priv. - Andrew Lunn comments Changes v1->v2: Link to v1: https://lore.kernel.org/netdev/20241218105023.2237645-1-tianx@yunsilicon.com/ 1. Remove the last two patches to reduce the total code submitted. - Jakub Kicinski comments 2. Remove the custom logging interfaces and switch to using pci_xxx/netdev_xxx logging interfaces. Delete the related module parameters. 3. No use of inline functions in .c files. 4. Remove unnecessary license information. 5. Remove unnecessary void casts. - Andrew Lunn comments 6. Use double underscore (__) for header file macros. 7. Fix the depend field in Kconfig. 8. Add sign-off for co-developers. 9. use string directly in MODULE_DESCRIPTION 10. Fix poor formatting issues in the code. 11. Modify some macros that don't use the XSC_ prefix. 12. Remove unused code from xsc_cmd.h that is not part of this patch series. 13. No comma after items in a complete enum. 14. Use the BIT() macro to define constants related to bit operations. 15. Add comments to clarify names like ver, cqe, eqn, pas, etc. - Przemek Kitszel comments Changes v0->v1: 1. name xsc_core_device as xdev instead of dev 2. modify Signed-off-by tag to Co-developed-by 3. remove some obvious comments 4. remove unnecessary zero-init and NULL-init 5. modify bad-named goto labels 6. reordered variable declarations according to the RCT rule - Przemek Kitszel comments 7. add MODULE_DESCRIPTION() - Jeff Johnson comments 8. remove unnecessary dev_info logs 9. replace these magic numbers with #defines in xsc_eth_common.h 10. move code to right place 11. delete unlikely() used in probe 12. remove unnecessary reboot callbacks - Andrew Lunn comments Xin Tian (14): net-next/yunsilicon: Add xsc driver basic framework net-next/yunsilicon: Enable CMDQ net-next/yunsilicon:
