* [POWERPC] QE: fix Kconfig 'select' warning with UCC_FASTTimur Tabi2007-05-23
| | | | | | | | | | | The UCC_GETH Kconfig option in drivers/net/Kconfig had a line to select the UCC_FAST option is arch/powerpc/sysdev/qe_lib/Kconfig, which is only used on PowerPC builds. On other architectures, this would generated a warning. The fix is to have UCC_FAST depend on UCC_GETH.

| | | | | | | | | | | | | | | Sam's recent change in 7664709b44a13e2e0b545e2dd8e7b8797a1748dc broke things for us because we ended up with *(.text.*) before *(.text), whereas previously *(.text) was first. This was important because the start of the text section contains the kernel entry point. In fact, we don't need that *(.text.*) thing anymore and it incorrectly matched .text.init.refok, thus putting it before .text. .. ouch !

| * | IB/cm: Improve local id allocationMichael S. Tsirkin2007-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IB CM uses an idr for local id allocations, with a running counter as start_id. This fails to generate distinct ids if 1. An id is constantly created and destroyed 2. A chunk of ids just beyond the current next_id value is occupied This in turn leads to an increased chance of connection request being mis-detected as a duplicate, sometimes for several retries, until next_id gets past the block of allocated ids. This has been observed in practice. As a fix, remember the last id allocated and start immediately above it. This also fixes a problem with the old code, where next_id might overflow and become negative. Signed-off-by: Michael S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SRQ WR leakage has been observed with IPoIB/CM: e.g. flipping ports on and off will, with time, leak out all WRs and then all connections will start getting RNR NAKs. Fix this in the way suggested by spec: move the QP being destroyed to the error state, wait for "Last WQE Reached" event and then post WR on a "drain QP" connected to the same CQ. Once we observe a completion on the drain QP, it's safe to call ib_destroy_qp. Signed-off-by: Michael S. Tsirkin <mst@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
