| * [SCSI] bnx2i: Fixed kernel panic due to illegal usage of sc->request->cpuEddie Wai2011-07-211-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A kernel panic was observed when passing the sc->request->cpu = -1 to retrieve the per_cpu variable pointer: #0 [ffff880011203960] machine_kexec at ffffffff81022bc3 #1 [ffff8800112039b0] crash_kexec at ffffffff81088630 #2 [ffff880011203a80] __die at ffffffff8139ea20 #3 [ffff880011203aa0] no_context at ffffffff8102f3a7 #4 [ffff880011203ae0] __bad_area_nosemaphore at ffffffff8102f665 #5 [ffff880011203ba0] retint_signal at ffffffff8139dd1f #6 [ffff880011203cc8] bnx2i_indicate_kcqe at ffffffffa03dc4f2 #7 [ffff880011203da8] service_kcqes at ffffffffa03cb04f #8 [ffff880011203e68] cnic_service_bnx2x_kcq at ffffffffa03cb14a #9 [ffff880011203e88] cnic_service_bnx2x_bh at ffffffffa03cb1b3 The problem lies in the slow path sg_io (and perhaps sg_scsi_ioctl) call to blk_get_request->get_request/wait->blk_alloc_request->blk_rq_init which re-initializes the request->cpu to -1. There is no assignment for cpu from that to the request_fn call to low level drivers. When this happens, the sc->request->cpu will be using the init value of -1. This will create a kernel panic when it hits bnx2i because the code refers it to get the per_cpu variables ptr. This change is to put in a guard against that and also for cases when bio affinity/queue completion to the same cpu is not enabled. In those cases, the request->cpu will remain a -1 also. This bug was created from commit: b5cf6b63f73abdc051035f0050b367beeb2ef94c For the case when the blk layer did not setup the request->cpu, bnx2i will complete the sc with the current CPU of the thread.

| * [SCSI] bnx2i: Added the use of kthreads to handle SCSI cmd completionEddie Wai2011-06-294-35/+333
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch breaks the SCSI cmd completion into two parts: 1. The bh will allocate and queued work to the cmd specific CPU IO completion kthread. The CPU for the cmd is from the sc->request->cpu. 2. The CPU specific IO completion kthread will call the scsi_cmd_resp routine to do the actual cmd completion. In the normal case, these IO completion kthreads should complete before the blk IO times out at 60s. However, in the case when these kthreads are blocked for whatever reason and exceeded the timeout, the call to conn_destroy will have to iterate and exhaust all related work in the percpu work list for all online CPUs. This will guarantee the protection of the work->session and conn pointers before they get freed. Also modified the event coalescing formula to have at least the event_coal_min outstanding cmds in the pipeline so the SCSI producer would not get underrun. Also changed the following SCSI parameters: - can_queue from 1024 to 2048 - cmds_per_lun from 24 to 128 Signed-off-by: Eddie Wai <eddie.wai@broadcom.com> Acked-by: Benjamin Li <benli@broadcom.com> Acked-by: Michael Chan <mchan@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

|/ | | | | | | | | | | | | | | | | | | | | | | | | | New FW/HSI (7.0): - Added support to 578xx chips - Improved HSI - much less driver's direct access to the FW internal memory needed. New implementation of the HSI handling layer in the bnx2x (bnx2x_sp.c): - Introduced chip dependent objects that have chip independent interfaces for configuration of MACs, multicast addresses, Rx mode, indirection table, fast path queues and function initialization/cleanup. - Objects functionality is based on the private function pointers, which allows not only a per-chip but also PF/VF differentiation while still preserving the same interface towards the driver. - Objects interface is not influenced by the HSI changes which do not require providing new parameters keeping the code outside the bnx2x_sp.c invariant with regard to such HSI chnages. Changes in a CNIC, bnx2fc and bnx2i modules due to the new HSI.

* [SCSI] bnx2i: Optimized the iSCSI offload performanceEddie Wai2011-05-243-19/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modified the event coalescing code for iSCSI offload to combat both corner cases and optimize performance as follows: 1. Added mechanism to loop back a second time to process any leftover CQEs that was generated by the hardware during the time the driver is busy processing previous CQEs in the bh. This not only helps the performance but also fixes the corner case when no more CQEs are being generated in the pipeline; so those leftover CQEs will get a a chance to be processed. 2. Added ARM_CQE_FP to distinguish between fast path arming versus slow path arming. This change will guarantee that the CQEs will always get a chance to be re-armed during fast path completions. 3. Removed the inline event coalescing division for perf optimization. Also fixed a division-by-zero error when the event_coal_div module param was set to 0. 4. Changed the default SQ WQEs size from 256 to 128 to match chip default. 5. Changed the cmd_per_lun from 32 to 24.

* [SCSI] bnx2i: Fixed packet error created when the sq_size is set to 16Eddie Wai2011-05-242-0/+4
| | | | | | | | | | | | | | The number of chip's internal command cell, which is use to generate SCSI cmd packets to the target, was not initialized correctly by the driver when the sq_size is changed from the default 128. This, in turn, will create a problem where the chip's transmit pipe will erroneously reuse an old command cell that is no longer valid. The fix is to correctly initialize the chip's command cell upon setup.

| * [SCSI] bnx2i: Added fix for NOP-Out response panic from unsolicited NOP-InEddie Wai2010-12-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch fixes the following situations where NOP-Out pkt is called for: - local unsolicited NOP-Out requests (requesting no NOP-In response) - local NOP-Out responses to unsolicited NOP-In requests kernel panic is observed due to double session spin_lock requests; one in the bnx2i_process_nopin_local_cmpl routine in bnx2i_hwi.c and the other in the iscsi_put_task routine in libiscsi.c The proposed fix is to export the currently static __iscsi_put_task() routine and have bnx2i call it directly instead of the iscsi_put_task() routine which holds the session spin lock.

| | | | | | | | | | | | | | | | | | | | | | | | | | The bnx2x devices require a 2 second quiet time before sending the last RAMROD command to destroy a connection. This sleep wait adds up to a long delay when iscsid is serially destroying maultiple connections. Create a workqueue to perform the final connection cleanup in the background to speed up the process. This significantly speeds up the process as the wait time can be done in parallel for multiple connections. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.
