net/mlx5e: Add handle SHAMPO cqe support

2021-10-27T02:30:40+00:00

This patch adds the new CQE SHAMPO fields: - flush: indicates that we must close the current session and pass the SKB to the network stack. - match: indicates that the current packet matches the oppened session, the packet will be merge into the current SKB. - header_size: the size of the packet headers that written into the headers buffer. - header_entry_index: the entry index in the headers buffer. - data_offset: packets data offset in the WQE. Also new cqe handler is added to handle SHAMPO packets: - The new handler uses CQE SHAMPO fields to build the SKB. CQE's Flush and match fields are not used in this patch, packets are not merged in this patch. Signed-off-by: Khalid Manaa Reviewed-by: Tariq Toukan Signed-off-by: Saeed Mahameed

net/mlx5e: Add support to klm_umr_wqe

2021-10-27T02:30:39+00:00

This commit adds the needed definitions for using the klm_umr_wqe. UMR stands for user-mode memory registration, is a mechanism to alter address translation properties of MKEY by posting WorkQueueElement aka WQE on send queue. MKEY stands for memory key, MKEY are used to describe a region in memory that can be later used by HW. KLM stands for {Key, Length, MemVa}, KLM_MKEY is indirect MKEY that enables to map multiple memory spaces with different sizes in unified MKEY. klm_umr_wqe is a UMR that use to update a KLM_MKEY. SHAMPO feature uses KLM_MKEY for memory registration of his header buffer. Signed-off-by: Ben Ben-Ishay Reviewed-by: Tariq Toukan Signed-off-by: Saeed Mahameed

net/mlx5: Add SHAMPO caps, HW bits and enumerations

2021-10-27T02:30:39+00:00

This commit adds SHAMPO bit to hca_cap and SHAMPO capabilities structure, SHAMPO related HW spec hardware fields and enumerations. SHAMPO stands for: split headers and merge payload offload. SHAMPO new fields: WQ: - headers_mkey: mkey that represents the headers buffer, where the packets headers will be written by the HW. - shampo_enable: flag to verify if the WQ supports SHAMPO feature. - log_reservation_size: the log of the reservation size where the data of the packet will be written by the HW. - log_max_num_of_packets_per_reservation: log of the maximum number of packets that can be written to the same reservation. - log_headers_entry_size: log of the header entry size of the headers buffer. - log_headers_buffer_entry_num: log of the entries number of the headers buffer. RQ: - shampo_no_match_alignment_granularity: the HW alignment granularity in case the received packet doesn't match the current session. - shampo_match_criteria_type: the type of match criteria. - reservation_timeout: the maximum time that the HW will hold the reservation. mlx5_ifc_shampo_cap_bits, the capabilities of the SHAMPO feature: - shampo_log_max_reservation_size: the maximum allowed value of the field WQ.log_reservation_size. - log_reservation_size: the minimum allowed value of the field WQ.log_reservation_size. - shampo_min_mss_size: the minimum payload size of packet that can open a new session or be merged to a session. - shampo_max_log_headers_entry_size: the maximum allowed value of the field WQ.log_headers_entry_size Signed-off-by: Ben Ben-Ishay Reviewed-by: Tariq Toukan Signed-off-by: Saeed Mahameed

net/mlx5: Extend health buffer dump

2021-10-25T20:51:19+00:00

Enhance health buffer to include: - assert_var5: expose the 6'th assert variable. - time: error's time-stamp in seconds (epoch time). - rfr: Recovery Flow Requiered. When set, indicates that the error cannot be recovered without flow involving reset. - severity: error's severity value, ranging from emergency to debug. Expose them in the health buffer dump (dmesg and devlink fw reporter). Health buffer in dmesg: mlx5_core 0000:08:00.0: print_health_info:425:(pid 912): Health issue observed, firmware internal error, severity(3) ERROR: mlx5_core 0000:08:00.0: print_health_info:429:(pid 912): assert_var[0] 0x08040700 mlx5_core 0000:08:00.0: print_health_info:429:(pid 912): assert_var[1] 0x00000000 mlx5_core 0000:08:00.0: print_health_info:429:(pid 912): assert_var[2] 0x00000000 mlx5_core 0000:08:00.0: print_health_info:429:(pid 912): assert_var[3] 0x00000000 mlx5_core 0000:08:00.0: print_health_info:429:(pid 912): assert_var[4] 0x00000000 mlx5_core 0000:08:00.0: print_health_info:429:(pid 912): assert_var[5] 0x00000000 mlx5_core 0000:08:00.0: print_health_info:432:(pid 912): assert_exit_ptr 0x00aaf800 mlx5_core 0000:08:00.0: print_health_info:434:(pid 912): assert_callra 0x00aaf70c mlx5_core 0000:08:00.0: print_health_info:436:(pid 912): fw_ver 16.32.492 mlx5_core 0000:08:00.0: print_health_info:437:(pid 912): time 1634819758 mlx5_core 0000:08:00.0: print_health_info:438:(pid 912): hw_id 0x0000020d mlx5_core 0000:08:00.0: print_health_info:439:(pid 912): rfr 0 mlx5_core 0000:08:00.0: print_health_info:440:(pid 912): severity 3 (ERROR) mlx5_core 0000:08:00.0: print_health_info:441:(pid 912): irisc_index 9 mlx5_core 0000:08:00.0: print_health_info:442:(pid 912): synd 0x1: firmware internal error mlx5_core 0000:08:00.0: print_health_info:444:(pid 912): ext_synd 0x802b mlx5_core 0000:08:00.0: print_health_info:445:(pid 912): raw fw_ver 0x102001ec Signed-off-by: Aya Levin Reviewed-by: Moshe Shemesh Signed-off-by: Saeed Mahameed

net/mlx5: Allocate individual capability

2021-08-11T18:14:33+00:00

Currently mlx5_core_dev contains array of capabilities. It contains 19 valid capabilities of the device, 2 reserved entries and 12 holes. Due to this for 14 unused entries, mlx5_core_dev allocates 14 * 8K = 112K bytes of memory which is never used. Due to this mlx5_core_dev structure size is 270Kbytes odd. This allocation further aligns to next power of 2 to 512Kbytes. By skipping non-existent entries, (a) 112Kbyte is saved, (b) mlx5_core_dev reduces to 8KB with alignment (c) 350KB saved in alignment In future individual capability allocation can be used to skip its allocation when such capability is disabled at the device level. This patch prepares mlx5_core_dev to hold capability using a pointer instead of inline array.
