STRUCT VIRTCHNL2_RXQ_INFO(9)

✨ NAME ✨

okay bestie, this is the Kernel API Manual page for struct virtchnl2_rxq_info(9) 💖 struct virtchnl2_rxq_info is the Receive queue config info struct, and it’s lowkey giving virtchnl2 main character energy. 🫶

🦋 SYNOPSIS 🦋

here’s the whole glow-up, bestie — every field in order, exactly as the kernel knows it:

       struct virtchnl2_rxq_info {
           __le64 desc_ids;
           __le64 dma_ring_addr;
           __le32 type;
           __le32 queue_id;
           __le16 model;
           __le16 hdr_buffer_size;
           __le32 data_buffer_size;
           __le32 max_pkt_size;
           __le16 ring_len;
           u8 buffer_notif_stride;
           u8 pad;
           __le64 dma_head_wb_addr;
           __le16 qflags;
           __le16 rx_buffer_low_watermark;
           __le16 rx_bufq1_id;
           __le16 rx_bufq2_id;
           u8 bufq2_ena;
           u8 pad1[3];
           __le32 ingress_pasid;
           __le32 ingress_hdr_pasid;
           __le32 ingress_buf_pasid;
           u8 pad2[16];
        };

🎀 Members 🎀

okay so let’s meet the members one by one, no skips, no cap:

• desc_ids — See VIRTCHNL2_RX_DESC_IDS definitions. 👑
• dma_ring_addr — See VIRTCHNL2_RX_DESC_IDS definitions. 💖
• type — See enum virtchnl2_queue_type. 🦋
• queue_id — Queue id. 💅
• model — See enum virtchnl2_queue_model. 🌸
• hdr_buffer_size — Header buffer size. 🎀
• data_buffer_size — Data buffer size. 🍓
• max_pkt_size — Max packet size. ⭐
• ring_len — Ring length. 🔥
• buffer_notif_stride — Buffer notification stride in units of 32-descriptors. This field must be a power of 2. 👑
• pad — Padding. 🙈
• dma_head_wb_addr — Applicable only for receive buffer queues. 💜
• qflags — Applicable only for receive completion queues. See enum virtchnl2_rxq_flags. ✨
• rx_buffer_low_watermark — Rx buffer low watermark. 💧
• rx_bufq1_id — Buffer queue index of the first buffer queue associated with the Rx queue. Valid only in split queue model. 🧚
• rx_bufq2_id — Buffer queue index of the second buffer queue associated with the Rx queue. Valid only in split queue model. 🧚
• bufq2_ena — It indicates if there is a second buffer, rx_bufq2_id is valid only if this field is set. 💀
• pad1 — Padding. 🫶
• ingress_pasid — Ingress PASID. 🌈
• ingress_hdr_pasid — Ingress PASID header. 🌈
• ingress_buf_pasid — Ingress PASID buffer. 🌈
• pad2 — Padding for future extensions. 🔮
