* IB/ehca: Replace get_paca()->paca_index by the more portable ↵Joachim Fenkes2007-10-091-7/+7
| | | | | | | | | | raw_smp_processor_id() We can use raw_smp_processor_id() here because the processor ID is only used for debug output and therefore our use is preemption-unsafe. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ehca: ehca_gen_warn() should always printJoachim Fenkes2007-10-091-6/+3

* IB/ehca: Move ehca2ib_return_code() out of lineHoang-Nam Nguyen2007-07-201-18/+1
| | | | | | | | ehca2ib_return_code() is not used in any fast path, and making it non-inline saves ~1.5K of code. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ehca: Fix warnings issued by checkpatch.plHoang-Nam Nguyen2007-07-171-14/+14
| | | | | | | | Run the existing ehca code through checkpatch.pl and clean up the worst of the coding style violations. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ehca: Use common error code mapping instead of specific onesHoang-Nam Nguyen2007-07-171-0/+3
| | | | | | | | | 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>
* IB/ehca: Refactor sync between completions and destroy_cq using atomic_tJoachim Fenkes2007-07-091-0/+1
| | | | | | | | | | - ehca_cq.nr_events is made an atomic_t, eliminating a lot of locking. - The CQ is removed from the CQ idr first now to make sure no more completions are scheduled on that CQ. The "wait for all completions to end" code becomes much simpler this way. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ehca: Fix eHCA driver compilation for uniprocessorPaul Mackerras2006-10-301-0/+1
| | | | | | | | | | The eHCA driver does not compile for a uniprocessor configuration (CONFIG_SMP=n), due to H_SUCCESS and other symbols being undefined. This fixes it.

* IB/ehca: Tweak trace message formatHoang-Nam Nguyen2006-10-021-1/+1

* IB/ehca: Add driver for IBM eHCA InfiniBand adaptersHeiko J Schick2006-09-221-0/+172
Add a driver for IBM GX bus InfiniBand adapters, which are usable with some pSeries/System p systems. Signed-off-by: Heiko J Schick <schickhj.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
