* [infiniband] Return status code from ib_create_cq() and ib_create_qp()Michael Brown2017-03-222-20/+16Star
| | | | | | | | | | | | Any underlying errors arising during ib_create_cq() or ib_create_qp() are lost since the functions simply return NULL on error. This makes debugging harder, since a debug-enabled build is required to discover the root cause of the error. Fix by returning a status code from these functions, thereby allowing any underlying errors to be propagated. Signed-off-by: Michael Brown <mcb30@ipxe.org>

| | | | | | | | When the area to be mapped straddles the 2GB boundary, the expression (high+size) will overflow on the first loop iteration. Fix by using (end-size), which cannot underflow. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [qib7322] Validate payload lengthMichael Brown2016-03-301-3/+10
| | | | | | | | | | | There is no way for the hardware to give us an invalid length in the LRH, since it must have parsed this length field in order to perform header splitting. However, this is difficult to prove conclusively. Add an unnecessary length check to explicitly reject any packets larger than the posted receive I/O buffer.

* [arbel] Allocate space for GRH on UD queue pairsMichael Brown2016-03-212-16/+55
| | | | | | | As with the previous commit (for Hermon), allocate a separate ring buffer to hold received GRHs. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [hermon] Allocate space for GRH on UD queue pairsMichael Brown2016-03-212-12/+47
| | | | | | | | | | | | | | | | | | | | | | | | | The Infiniband specification (volume 1, section 11.4.1.2 "Post Receive Request") notes that for UD QPs, the GRH will be placed in the first 40 bytes of the receive buffer if present. (If no GRH is present, which is normal, then the first 40 bytes of the receive buffer will be unused.) Mellanox hardware performs this placement automatically: other headers will be stripped (and their values returned via the CQE), but the first 40 bytes of the data buffer will be consumed by the (probably non-existent) GRH. This does not fit neatly into iPXE's internal abstraction, which expects the data buffer to represent just the data payload with the addresses from the GRH (if present) passed as additional parameters to ib_complete_recv(). The end result of this discrepancy is that attempts to receive full-sized 2048-byte IPoIB packets on Mellanox hardware will fail. Fix by allocating a separate ring buffer to hold the received GRHs.

* [hermon] Ensure hardware is quiescent when no interfaces are openMichael Brown2011-11-152-81/+217
| | | | | | | | | | | | | WinPE has been observed to call PXENV_UNDI_SHUTDOWN but not PXENV_STOP_UNDI. This means that Hermon hardware is left partially active (firmware running and one event queue mapped) when WinPE starts up, which can cause a Blue Screen of Death. Fix by ensuring that the hardware is left quiescent (with the firmware stopped) when no interfaces are open.

* [arbel] Add (not-yet-functional) support for RC queue pairsMichael Brown2011-10-242-8/+111
| | | | | | | | | | | | | Arbel seems to crash the system as soon as the first send WQE completes on an RC queue pair. (NOPs complete successfully, so this is a problem specific to the work queue rather than the completion queue.) The cause of this problem has remained unknown for over a year. Check in the non-functioning code to avoid bit-rot, and in the hope that someone will find the fix. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [hermon] Remove temporary workaround for missing BOFM mport supportMichael Brown2011-05-041-39/+15Star

* [hermon] Work around missing mport support in current BOFM implementationsMichael Brown2011-04-081-15/+39
| | | | | | | | | | | | | | | | | | | | | | | Current BOFM versions are unable to create entries with mport>1, which means that only the port 1 MAC address can be explicitly specified. Work around this by using the provided MAC address as a base address for all subsequent ports. For example, if BOFM assigns the address 00:1A:64:76:00:09 for port 1 then we will assign the addresses 00:1A:64:76:00:09 for port 1 00:1A:64:76:00:0a for port 2 Future BOFM versions that may correctly support mport will work with this scheme without modification provided that the BOFM entries are created in increasing order of mport. Since BOFM tools tend to generate entries in increasing order (of slot, port, etc), this is not an unreasonable compromise. Signed-off-by: Michael Brown <mcb30@ipxe.org>
