2007-12-12IB/ehca: Serialize HCA-related hCalls if necessaryJoachim Fenkes
Several pSeries firmware versions share a rare locking issue in the HCA-related hCalls. Check for a feature flag that indicates the issue being fixed and serialize all HCA hCalls if not. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-11-13IB/ehca: Return physical link information in query_port()Joachim Fenkes
Newer firmware versions return physical port information to the partition, so hand that information to the consumer if it's present. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-07-17IB/ehca: Fix warnings issued by checkpatch.plHoang-Nam Nguyen
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>
2007-07-09IB/ehca: add Shared Receive Queue supportJoachim Fenkes
Support SRQs on eHCA2. Since an SRQ is a QP for eHCA2, a lot of code (structures, create, destroy, post_recv) can be shared between QP and SRQ. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-07-09IB/ehca: HW level, HW caps and MTU autodetectionJoachim Fenkes
In preparation for support of new eHCA2 features, change adapter probing: - Hardware level is changed to encode major and minor chip version - Hardware capabilities are queried from the firmware - The maximum MTU is queried from the firmware instead of assuming a fixed value Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-11-13IB/ehca: Use named constant for max mtuHoang-Nam Nguyen
Define and use a constant EHCA_MAX_MTU instead hardcoded value. Signed-off-by: Hoang-Nam Nguyen <hnguyen@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ehca: Add driver for IBM eHCA InfiniBand adaptersHeiko J Schick
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>
