They cannot handle the pcie_caps of 0x51 (MaxReadReq 4096, MaxPayload=256). A typical diagnostic in this situation reported by syslog contains the text: [PCIe Poisoned TLP][Send DMA memory read] Restore the module paramter default to zero with will avoid any changes in the root complex.

However, the ConnectX firmware is able to handle such MADs. For unsupported attributes, the firmware returns a GET_RESPONSE MAD containing an error status. For example, for a FDR-10 node with LID 11: # ibstat mlx4_0 1 CA: 'mlx4_0' Port 1: State: Active Physical state: LinkUp Rate: 40 (FDR10) Base lid: 11 LMC: 0 SM lid: 24 Capability mask: 0x02514868 Port GUID: 0x0002c903002e65d1 Link layer: InfiniBand Extended Port Query (EPI) vendor mad timeouts before the patch: # smpquery MEPI 11 -d ibwarn: [4196] smp_query_via: attr 0xff90 mod 0x0 route Lid 11 ibwarn: [4196] _do_madrpc: retry 1 (timeout 1000 ms) ibwarn: [4196] _do_madrpc: retry 2 (timeout 1000 ms) ibwarn: [4196] _do_madrpc: timeout after 3 retries, 3000 ms ibwarn: [4196] mad_rpc: _do_madrpc failed; dport (Lid 11) smpquery: iberror: [pid 4196] main: failed: operation EPI: ext port info query failed EPI query works OK with the patch: # smpquery MEPI 11 -d ibwarn: [6548] smp_query_via: attr 0xff90 mod 0x0 route Lid 11 ibwarn: [6548] mad_rpc: data offs 64 sz 64 mad data 0000 0000 0000 0001 0000 0001 0000 0001 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 # Ext Port info: Lid 11 port 0 StateChangeEnable:...............0x00 LinkSpeedSupported:..............0x01 LinkSpeedEnabled:................0x01 LinkSpeedActive:.................0x01 Signed-off-by: Jack Morgenstein <jackm@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Acked-by: Ira Weiny <weiny2@llnl.gov> Cc: <stable@vger.kernel.org> Signed-off-by: Roland Dreier <roland@purestorage.com>

* module_param: avoid bool abuse, add bint for special cases.Rusty Russell2012-01-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For historical reasons, we allow module_param(bool) to take an int (or an unsigned int). That's going away. A few drivers really want an int: they set it to -1 and a parameter will set it to 0 or 1. This sucks: reading them from sysfs will give 'Y' for both -1 and 1, but if we change it to an int, then the users might be broken (if they did "param" instead of "param=1"). Use a new 'bint' parser for them. (ntfs has a different problem: it needs an int for debug_msgs because it's also exposed via sysctl.)

The following two parameters are changed: - rcvhdrcnt to twice the rcvegrcnt - pcie_caps=0x51 The rcvhdrcnt at twice the egrcount allows the preemptive NAK code during reception to function in 100% of the cases rather than a sender jiffies-based timeout. The pcie_caps default of 0x51 will set the proposed MaxPayload and MaxReceiveReqest to 256 and 4096 respectively. The capabilities on the root complex will be used to limit those values.

This patch only locks the pending_lock, assuming that the empty case is an exeception, in which case the pending_lock is dropped, and the original code is executed. This will save a lock of s_lock in the normal case. The observation is that the sdma descriptors will deplete at twice the rate of txreq's, so this should be rare.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For IBoE, SLs 0-7 are mapped to Ethernet 802.1Q user priority bits (pbits) which are part of the VLAN tag, SLs 8-15 are reserved. Under Ethernet, the ConnectX firmware treats (decode/encode) the four bit SL field in various constructs such as QPC / UD WQE / CQE as PPP0 and not as 0PPP. This correlates well to the fact that within the vlan tag the pbits are located in bits 15-13 and not 12-14. The current code wasn't consistent around that area - the encoding was correct for the IBoE QPC.path.schedule_queue field, but was wrong for IBoE CQEs and when MLX header was built. These inconsistencies resulted in wrong SL <--> wire 802.1Q pbits mapping, which is fixed by using SL <--> PPP0 all around the place.

| * | RDMA/cxgb4: Fix retry with MPAv1 logic for MPAv2Kumar Sanghvi2011-11-281-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Fix logic so that we don't retry with MPAv1 once we have done that already. Otherwise, we end up retrying with MPAv1 even when its not needed on getting peer aborts - and this could lead to kernel panic.

| * | RDMA/cxgb4: Fix iw_cxgb4 count_rcqes() logicJonathan Lallinger2011-11-281-1/+1
| |/ | | | | | | | | | | | | | | | | | | Fix another place in the code where logic dealing with the t4_cqe was using the wrong QID. This fixes the counting logic so that it tests against the SQ QID instead of the RQ QID when counting RCQES.

| * infiniband: add moduleparam.h to drivers/infiniband as requiredPaul Gortmaker2011-10-313-0/+3
| | | | | | | | | | | | | | | | These files were getting the moduleparam infrastructure from the implicit presence of module.h being everywhere, but that is going away soon. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
| * infiniband: add in export.h for files using EXPORT_SYMBOL/THIS_MODULEPaul Gortmaker2011-10-315-0/+5
| | | | | | | | | | | | | | | | | | These were getting it implicitly via device.h --> module.h but we are going to stop that when we clean up the headers. Fix these in advance so the tree remains biscect-clean. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
| * infiniband: Fix up module files that need to include module.hPaul Gortmaker2011-10-3112-0/+14
| | | | | | | | | | | | | | | | They had been getting it implicitly via device.h but we can't rely on that for the future, due to a pending cleanup so fix it now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | They get it via module.h (via device.h) but we want to clean that up. When we do, we'll get things like: CC [M] drivers/infiniband/core/sysfs.o sysfs.c:361: error: 'S_IRUGO' undeclared here (not in a function) sysfs.c:654: error: 'S_IWUSR' undeclared here (not in a function) so add in the stat header it is using explicitly in advance.
