2011-07-15IB/mthca: Stop returning separate error and status from FW commandsGoldwyn Rodrigues1-49/+44
Instead of having firmware command functions return an error and also a status, leading to code like: err = mthca_FW_COMMAND(..., &status); if (err) goto out; if (status) { err = -E...; goto out; } all over the place, just handle the FW status inside the FW command handling code (the way mlx4 does it), so we can simply write: err = mthca_FW_COMMAND(...); if (err) goto out; In addition to simplifying the source code, this also saves a healthy chunk of text: add/remove: 0/0 grow/shrink: 10/88 up/down: 510/-3357 (-2847) function old new delta static.trans_table 324 584 +260 mthca_cmd_poll 352 477 +125 mthca_cmd_wait 511 567 +56 mthca_table_put 213 240 +27 mthca_cleanup_db_tab 372 387 +15 __mthca_remove_one 314 323 +9 mthca_cleanup_user_db_tab 275 283 +8 __mthca_init_one 1738 1746 +8 mthca_cleanup 20 21 +1 mthca_MAD_IFC 1081 1082 +1 mthca_MGID_HASH 43 40 -3 mthca_MAP_ICM_AUX 23 20 -3 mthca_MAP_ICM 19 16 -3 mthca_MAP_FA 23 20 -3 mthca_READ_MGM 43 38 -5 mthca_QUERY_SRQ 43 38 -5 mthca_QUERY_QP 59 54 -5 mthca_HW2SW_SRQ 43 38 -5 mthca_HW2SW_MPT 60 55 -5 mthca_HW2SW_EQ 43 38 -5 mthca_HW2SW_CQ 43 38 -5 mthca_free_icm_table 120 114 -6 mthca_query_srq 214 206 -8 mthca_free_qp 662 654 -8 mthca_cmd 38 28 -10 mthca_alloc_db 1321 1311 -10 mthca_setup_hca 1067 1055 -12 mthca_WRITE_MTT 35 22 -13 mthca_WRITE_MGM 40 27 -13 mthca_UNMAP_ICM_AUX 36 23 -13 mthca_UNMAP_FA 36 23 -13 mthca_SYS_DIS 36 23 -13 mthca_SYNC_TPT 36 23 -13 mthca_SW2HW_SRQ 35 22 -13 mthca_SW2HW_MPT 35 22 -13 mthca_SW2HW_EQ 35 22 -13 mthca_SW2HW_CQ 35 22 -13 mthca_RUN_FW 36 23 -13 mthca_DISABLE_LAM 36 23 -13 mthca_CLOSE_IB 36 23 -13 mthca_CLOSE_HCA 38 25 -13 mthca_ARM_SRQ 39 26 -13 mthca_free_icms 178 164 -14 mthca_QUERY_DDR 389 375 -14 mthca_resize_cq 1063 1048 -15 mthca_unmap_eq_icm 123 107 -16 mthca_map_eq_icm 396 380 -16 mthca_cmd_box 90 74 -16 mthca_SET_IB 433 417 -16 mthca_RESIZE_CQ 369 353 -16 mthca_MAP_ICM_page 240 224 -16 mthca_MAP_EQ 183 167 -16 mthca_INIT_IB 473 457 -16 mthca_INIT_HCA 745 729 -16 mthca_map_user_db 816 798 -18 mthca_SYS_EN 157 139 -18 mthca_cleanup_qp_table 78 59 -19 mthca_cleanup_eq_table 168 149 -19 mthca_UNMAP_ICM 143 121 -22 mthca_modify_srq 172 149 -23 mthca_unmap_fmr 198 174 -24 mthca_query_qp 814 790 -24 mthca_query_pkey 343 319 -24 mthca_SET_ICM_SIZE 34 10 -24 mthca_QUERY_DEV_LIM 1870 1846 -24 mthca_map_cmd 1130 1105 -25 mthca_ENABLE_LAM 401 375 -26 mthca_modify_port 247 220 -27 mthca_query_device 884 850 -34 mthca_NOP 75 41 -34 mthca_table_get 287 249 -38 mthca_init_qp_table 333 293 -40 mthca_MODIFY_QP 348 308 -40 mthca_close_hca 131 89 -42 mthca_free_eq 435 390 -45 mthca_query_port 755 705 -50 mthca_free_cq 581 528 -53 mthca_alloc_icm_table 578 524 -54 mthca_multicast_attach 1041 986 -55 mthca_init_hca 326 271 -55 mthca_query_gid 487 431 -56 mthca_free_srq 524 468 -56 mthca_free_mr 168 111 -57 mthca_create_eq 1560 1501 -59 mthca_multicast_detach 790 728 -62 mthca_write_mtt 918 854 -64 mthca_register_device 1406 1342 -64 mthca_fmr_alloc 947 883 -64 mthca_mr_alloc 652 582 -70 mthca_process_mad 1242 1164 -78 mthca_dev_lim 910 830 -80 find_mgm 482 400 -82 mthca_modify_qp 3852 3753 -99 mthca_init_cq 1281 1181 -100 mthca_alloc_srq 1719 1610 -109 mthca_init_eq_table 1807 1679 -128 mthca_init_tavor 761 491 -270 mthca_init_arbel 2617 2098 -519 Signed-off-by: Goldwyn Rodrigues <rgoldwyn@suse.de>

They don't get updated by git and so they're worse than useless. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-04-16IB/mthca: Add IPoIB checksum offload supportEli Cohen1-0/+1
Arbel and Sinai devices support checksum generation and verification of TCP and UDP packets for UD IPoIB messages. This patch checks if the HCA supports this and sets the IB_DEVICE_UD_IP_CSUM capability flag if it does. It implements support for handling the IB_SEND_IP_CSUM send flag and setting the csum_ok field in receive work completions.

2006-04-10IB: simplify static rate encodingJack Morgenstein1-0/+1
Push translation of static rate to HCA format into low-level drivers, where it belongs. For static rate encoding, use encoding of rate field from IB standard PathRecord, with addition of value 0, for backwards compatibility with current usage. The changes are: - Add enum ib_rate to midlayer includes. - Get rid of static rate translation in IPoIB; just use static rate directly from Path and MulticastGroup records. - Update mthca driver to translate absolute static rate into the format used by hardware. This also fixes mthca's static rate handling for HCAs that are capable of 4X DDR. Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2005-08-26[PATCH] IB: move include files to include/rdmaRoland Dreier1-1/+1
Move the InfiniBand headers from drivers/infiniband/include to include/rdma. This allows InfiniBand-using code to live elsewhere, and lets us remove the ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2005-08-26[PATCH] IB/mthca: Use correct port width capability valueRoland Dreier1-2/+1
When we call the INIT_IB firmware command to bring up a port, use the actual port width capability returned by the QUERY_DEV_LIM command instead of always trying to enable both 1X and 4X. This fixes breakage seen when the firmware is build to allow 4X only. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2005-06-27[PATCH] IB/mthca: Align FW command mailboxes to 4KRoland Dreier1-20/+26
Future versions of Mellanox HCA firmware will require command mailboxes to be aligned to 4K. Support this by using a pci_pool to allocate all mailboxes. This has the added benefit of shrinking the source and text of mthca.

2005-04-16[PATCH] IB/mthca: fix MTT allocation in mem-free modeRoland Dreier1-1/+0
Fix bug in MTT allocation in mem-free mode. I misunderstood the MTT size value returned by the firmware -- it is really the size of a single MTT entry, since mem-free mode does not segment the MTT as the original firmware did. This meant that our MTT addresses ended up being off by a factor of 8. This meant that our MTT allocations might overlap, and so we could overwrite and corrupt earlier memory regions when writing new MTT entries. We fix this by always using our 64-byte MTT segment size. This allows some simplification of the code as well, since there's no reason to put the MTT segment size in a variable -- we can always use our enum value directly.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+310
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
