IB: Add CQ comp_vector support

2007-05-07T04:18:11Z

Add a num_comp_vectors member to struct ib_device and extend ib_create_cq() to pass in a comp_vector parameter -- this parallels the userspace libibverbs API. Update all hardware drivers to set num_comp_vectors to 1 and have all ULPs pass 0 for the comp_vector value. Pass the value of num_comp_vectors to userspace rather than hard-coding a value of 1. We want multiple CQ event vector support (via MSI-X or similar for adapters that can generate multiple interrupts), but it's not clear how many vectors we want, or how we want to deal with policy issues such as how to decide which vector to use or how to set up interrupt affinity. This patch is useful for experimenting, since no core changes will be necessary when updating a driver to support multiple vectors, and we know that we want to make at least these changes anyway.

IB/srp: Add orig_dgid sysfs attribute to scsi_host

2007-05-07T04:18:11Z

Add an orig_dgid attribute in sysfs for SRP scsi_hosts, so that userspace can tell what the original dgid value written to the add_target file was, even if the connection is redirected to a different port while connecting. Signed-off-by: Ishai Rabinovitz Signed-off-by: Roland Dreier

IB/srp: Don't wait for response when QP is in error state.

2007-02-04T22:11:56Z

When there is a call to send_tsk_mgmt SRP posts a send and waits for 5 seconds to get a response. When the QP is in the error state it is obvious that there will be no response so it is quite useless to wait. In fact, the timeout causes SRP to wait a long time to reconnect when a QP error occurs. (Each abort and each reset_device calls send_tsk_mgmt, which waits for the timeout). The following patch solves this problem by identifying the failure and returning an immediate error code.

IB/srp: Check match_strdup() return

2007-01-23T01:03:54Z

Checks if the kmalloc in match_strdup() was successful, and bail out on looking at the token if it failed. Signed-off-by: Ishai Rabinovitz Signed-off-by: Roland Dreier

IB/srp: Fix FMR mapping for 32-bit kernels and addresses above 4G

2006-12-15T22:01:49Z

struct srp_device.fmr_page_mask was unsigned long, which means that the top part of addresses above 4G was being chopped off on 32-bit architectures. Of course nothing good happens when data from SRP targets is DMAed to the wrong place. Fix this by changing fmr_page_mask to u64, to match the addresses actually used by IB devices. Thanks to Brian Cain and David McMillen for help diagnosing the bug and testing the fix. Signed-off-by: Roland Dreier

IB/srp: Fix memory leak on reconnect

2006-11-29T23:33:09Z

SRP reallocates the IU buffers for tx_ring and rx_ring without freeing the old buffers when it reconnects to a target. Fix this by keeping the old IU buffers around. Signed-off-by: Vu Pham Signed-off-by: Roland Dreier

Set the Scsi_Host's max_cmd_len from 12 (default) to 16 for SRP. Otherwise scsi_dispatch_cmd() won't pass down certain commands such as READ CAPACITY 16, required for supporting disks > 2TB. Signed-off-by: Arne Redlich Signed-off-by: Roland Dreier
