Message-Id: <20250409095552.2027686-1-tianx@yunsilicon.com> Date: Wed, 09 Apr 2025 17:56:39 +0800 From: "Xin Tian" <tianx@...silicon.com> To: <netdev@...r.kernel.org> Cc: <leon@...nel.org>, <andrew+netdev@...n.ch>, <kuba@...nel.org>, <pabeni@...hat.com>, <edumazet@...gle.com>, <davem@...emloft.net>, <jeff.johnson@....qualcomm.com>, <przemyslaw.kitszel@...el.com>, <weihg@...silicon.com>, <wanry@...silicon.com>, <jacky@...silicon.com>, <horms@...nel.org>, <parthiban.veerasooran@...rochip.com>, <masahiroy@...nel.org>, <kalesh-anakkur.purayil@...adcom.com>, <geert+renesas@...der.be>, <pabeni@...hat.com>, <geert@...ux-m68k.org> Subject: [PATCH net-next v10 00/14] xsc: ADD Yunsilicon XSC Ethernet Driver The patch series adds the xsc driver, which will support the YunSilicon MS/MC/MV series of network cards. 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 v9->v10 Link to v9: https://lore.kernel.org/netdev/20250318151449.1376756-1-tianx@yunsilicon.com/ - patch05: Remove GFP_ZERO from dma_alloc_coherent() (Jakub) - patch05: Add XSC_ prefix to all header guards (Jakub) - patch09: Replace ((struct xsc_adapter *)xdev->eth_priv)->netdev with a local variable (Jakub) - patches 02,09,11,12: Unify xsc_cmd_exec() return val: return -EIO for firmware errors.

RX channel (Simon) - patch12: Drop redundant adapter and adapter->xdev checks in xsc_eth_xmit_start() (Simon) - patch13: Remove XSC_SET/GET_PFLAG and other priv_flag-related code (Simon) - patch13: Initialize err to 0 in xsc_eth_post_rx_wqes() (Simon) - patch14: Return -ENOMEM if kvzalloc() for adapter->stats fails (Simon) Changes v8->v9: Link to v8: https://lore.kernel.org/netdev/20250307100824.555320-1-tianx@yunsilicon.com/ - correct netdev feature settings in Patch09 (Paolo) - change sizes from int to unsigned int in Patch02 (Geert) - nit in Patch02: min_t->min, use upper_32_bits/lower_32_bits() (Simon) Changes v7->v8: Link to v7: https://lore.kernel.org/netdev/20250228154122.216053-1-tianx@yunsilicon.com/ - add Kconfig NET_VENDOR_YUNSILICON depneds on COMPILE_TEST (Jakub) - rm unnecessary "default n" (Jakub) - select PAGE_POOL in ETH driver (Jakub) - simplify dma_mask set (Jakub) - del pci_state and pci_state_mutex (Kalesh) - I checked and droped intf_state and int_state_mutex too - del some no need lables in patch1 (Kalesh) - ensure consistent label naming throughout the patchset (Simon) - WARN_ONCE instead of meaningless comments (Simon) - Patch 7 add Reviewed-by from Leon Romanovsky, thanks Leon - nits Xin Tian (14): xsc: Add xsc driver basic framework xsc: Enable command queue xsc: Add hardware setup
