2007-10-12[SCSI] transport_srp: add rport roles attributeFUJITA Tomonori
This adds a 'roles' attribute to rport like transport_fc. The role can be initiator or target. That is, the initiator driver creates target remote ports and the target driver creates initiator remote ports.

2007-07-30IB/ipath: Workaround problem of errormask register being overwrittenDave Olson
On some system hardware, we are seeing moderately common cases of the chip errormask register being overwritten due to a chip bug in iba6120 that is triggered by a vendor-specific PCIe broadcast message. This patch merely checks periodically, and corrects it if needed (the overwrite can cause us to not get error and hardware error interrupts). Also, make dd->ipath_errormask the one, true canonical source for kr_errormask, and remove references to ipath_ignorederrs as it is currently unused.

2007-07-30IB/ipath: Fix some issues with buffer cancel and sendctrl register updateDave Olson
There was confused use of INFINIPATH_S_PIOBUFAVAILUPD (value) and IPATH_S_PIOBUFAVAILUPD (bit position). Also, some callers of ipath_cancel_sends() need kr_sendctrl restored, and some want to do it later. Signed-off-by: Dave Olson <dave.olson@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-07-30IB/ipath: Use faster put_tid_2 routine after initializationDave Olson
At one time the ipath_minrev field was initialized prior to the ipath_init_iba6120_funcs call, but that is no longer the case, so the slower put_tid routine was always being used. Signed-off-by: Dave Olson <dave.olson@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-07-30IB/ipath: Remove unsafe fastrcvint code from interrupt handlerDave Olson
The fastrcvint code's purpose was to avoid reading the interrupt status if kernel packets were in the receive queue (to reduce overhead). Because intstatus was not read, we could miss the error interrupt bit indicating freeze mode, since it only delivers a single interrupt, even if still pending after intclear is written. This patch removes that unsafe optimization. Signed-off-by: Dave Olson <dave.olson@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2007-07-29Remove fs.h from mm.hAlexey Dobriyan
Remove fs.h from mm.h. For this, 1) Uninline vma_wants_writenotify(). It's pretty huge anyway. 2) Add back fs.h or less bloated headers (err.h) to files that need it. As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files rebuilt down to 3444 (-12.3%).

2007-07-20IB/ehca: Support small QP queuesStefan Roscher
eHCA2 supports QP queues that can be as small as 512 bytes. This greatly reduces memory overhead for consumers that use lots of QPs with small queues (e.g. RDMA-only QPs). Apart from dealing with firmware, this code needs to manage bite-sized chunks of kernel pages, making sure that no kernel page is shared between different protection domains.

2007-07-20IB/mlx4: Fix error path in create_qp_common()Roland Dreier
The error handling code at err_wrid in create_qp_common() does not handle a userspace QP attached to an SRQ correctly, since it ends up in the else clause of the if statement. This means it tries to kfree() the uninitialized qp->sq.wrid and qp->rq.wrid pointers. Fix this so we only free the wrid arrays for kernel QPs. Pointed out by Michael S.

2007-07-20IB/ipath: Remove ipath_layer dead codeArthur Jones
The ipath_layer.[ch] code was an attempt to provide a single interface for the ipath verbs and ipath_ether code to use. As verbs functionality increased, the layer's functionality became insufficient and the verbs code broke away to interface directly to the driver. The failed attempt to get ipath_ether upstream was the final nail in the coffin and now it sits quietly in a dark kernel.org corner waiting for someone to notice the smell and send it along to it's final resting place.

2007-07-18IB/mthca: Simplify use of size0 in work request postingRoland Dreier
Current code sets size0 to 0 at the start of work request posting functions and then handles size0 == 0 specially within the loop over work requests. Change this so size0 is set along with f0 the first time through the loop (when nreq == 0). This makes the code easier to understand by making it clearer that f0 and size0 are always initialized if nreq != 0 without having to know that size0 == 0 implies nreq == 0. Also annotate size0 with uninitialized_var() so that this doesn't introduce a new compiler warning. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2007-07-17IB/mthca: Use uninitialized_var() for f0Roland Dreier
Commit 9db48926 ("drivers/infiniband/hw/mthca/mthca_qp: kill uninit'd var warning") added "= 0" to the declarations of f0 to shut up gcc warnings. However, there's no point in making the code bigger by initializing f0 to a random value just to get rid of a warning; setting f0 to 0 is no safer than just using uninitialized_var(), which documents the situation better and gives smaller code too.

2007-07-17IB/ehca: Use common error code mapping instead of specific onesHoang-Nam Nguyen
Instead of one error mapping function for each potential error source in ehca_mrmw.c, use a centralized function that handles all cases, saving a three-figure line count. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2007-07-17IB/ehca: Fix HW level autodetectionJoachim Fenkes
Autodetection was missing a few HW revisions, causing certain eHCA1 revisions to be treated like eHCA2. Fixed. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-07-17IB/mlx4: Take sizeof the correct pointer in call to memset()Dotan Barak
When clearing the ib_ah_attr parameter in to_ib_ah_attr(), use sizeof *ib_ah_attr instead of sizeof *path. This is the same bug as was fixed for mthca in 99d4f22e ("IB/mthca: Use correct structure size in call to memset()"), but the code was cut and pasted into mlx4 before the fix was merged.
