* [hermon] Add missing __attribute__ (( packed ))Michael Brown2011-02-171-2/+2
| | | | | | | | | | On 64-bit builds, MLX_DECLARE_STRUCT() produces a structure that is always a multiple of 64 bits long, causing the HCR structure to be over-length by one dword. This in turn causes hermon_cmd() to write beyond the end of the HCR, which causes commands to fail. Reported-by: Itay Gazit <itayg@mellanox.co.il> Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [hermon] Use SET_PORT to set port parametersMichael Brown2010-09-212-23/+89

* [arbel] Allocate only as much memory as is needed for firmware and ICMMichael Brown2010-09-181-26/+66
| | | | | | | | Use individual page mappings rather than a single whole-region mapping, to avoid the waste of memory that occurs due to the constraint that each mapped block must be aligned on its own size. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [arbel] Optimise ICM layout to reduce overall memory usageMichael Brown2010-09-172-75/+136
| | | | | | | | | | Reduce the amount of ICM space required by choosing to order the various allocations in approximately descending order of alignment requirements. This saves approximately 512kB of host memory. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [arbel] Perform ICM allocations according to the specificationMichael Brown2010-09-172-44/+87
| | | | | | | | | | | The current method for ICM allocation exactly matches the addresses chosen by the old Etherboot driver, but does not match the specification. Some ICM tables (notably the queue pair context table) therefore end up incorrectly aligned. Fix by performing allocations as per the specification. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [arbel] Map all event types to our event queueMichael Brown2010-09-172-5/+21
| | | | | | | | | | | | | Only port state change events are currently mapped to our event queue, since those are the only events we are prepared to handle. This ignores a potentially useful source of diagnostic information in the case of unexpected failures. Fix by mapping all events to the event queue; a build with debugging enabled will therefore at least dump the raw content of the unexpected events. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [infiniband] Add node GUID as distinct from the first port GUIDMichael Brown2010-09-162-1/+5
| | | | | | | | | | | | | | | iPXE currently uses the first port's port GUID as the node GUID, rather than using the (possibly distinct) real node GUID. This can confuse opensm during the handover to a loaded OS: it thinks the port already belongs to a different node and so discards our port information with a warning message about duplicate ports. Everything is picked up correctly on the second subnet sweep, after opensm has established that the "old" node no longer exists, but this can delay link-up unnecessarily by several seconds. Fix by using the real node GUID. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [arbel] Poll for link state changes while DOWNMichael Brown2010-09-161-0/+9

* [infiniband] Always call ib_link_state_changed() in ib_smc_update()Michael Brown2010-09-162-12/+5Star
| | | | | | | | | | | | | | ib_smc_update() potentially updates the Infiniband port state, and so should almost always be followed by a call to ib_link_state_changed(). The one exception is the call made to ib_smc_update() before the device is registered. Fix by removing explicit calls to ib_link_state_changed() from drivers using ib_smc_update(), including a call to ib_link_state_changed() within ib_smc_update(), and creating a separate ib_smc_init() for use prior to device registration.

* [hermon] Use correct alignment for doorbell recordsMichael Brown2010-09-122-11/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | Doorbell records are currently embedded within the completion queue and receive work queue strucures, which are allocated using zalloc() and so have an alignment guarantee of only sizeof(void*), i.e. four bytes. This is sufficient for the receive work queue, but not for the completion queue, which requires an alignment guarantee of eight bytes. Though not guaranteed, it so happens that zalloc() will always return a pointer that is exactly four bytes above a sixteen-byte boundary. The completion queue doorbell record is therefore always misaligned, and the value passed to the hardware via SW2HW_CQ is actually always pointing to the page_offset value within the MTT descriptor (which directly precedes the inline doorbell record). Provided that the page offset is greater than 0x100, this looks to the hardware like an update_ci value of greater than 0x010000 (taking into account endianness differences), and so the hardware will happily deliver more than 0x010000 completions before stopping. Hence this problem is rarely observable. Fix by allocating the doorbell records separately and using the correct alignment constraints. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [hermon] Set event queue number for completion queuesMichael Brown2010-09-121-0/+1
| | | | | | | | Give completion queues a chance to deliver exception events by programming in the number of our event queue (currently used only for port state changes). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [hermon] Improve debugging output and facilitiesMichael Brown2010-09-122-91/+180
| | | | | | | | | | | Improve the utility of debugging messages by including the relevant port number, queue number (QPN, CQN, EQN), work queue entry (WQE) number, and physical addresses wherever applicable. Add hermon_dump_cqctx() for dumping a completion queue context, and hermon_fill_nop_send_wqe() for inserting NOPs into send work queues. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [build] Rename gPXE to iPXEMichael Brown2010-04-206-30/+30
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain. Work around this problem by renaming project from gPXE to iPXE, and updating URLs to match. Also update README, LOG and COPYRIGHTS to remove obsolete information.

* [linda] Re-import the latest register definitionsMichael Brown2009-11-161-6/+4Star
| | | | | Two registers have been renamed, and a bugfix to qib_genbits.pl removes a harmless excess padding field.
* [susieq] Update qib_genbits.pl to handle SusieQ definitionsMichael Brown2009-11-161-4/+24
| | | | | | The latest RTL-generated register lists include (mostly redundant) xxx_MSB values alongside xxx_LSB and xxx_RMASK, and also include default register values.
* [linda] Wait up to 20us for link state to updateMichael Brown2009-11-162-0/+35
| | | | | | | | | | Some subnet managers expect the GetResponse from a SetPortInfo MAD to contain the new link state. The transition is not immediate, so we often end up returning the previous link state. This can cause the SM to fail to activate the port. Fix by waiting for up to 20us for the link state transition to take effect.
* [hermon] Reset device during probe()Michael Brown2009-10-142-0/+28
| | | | | | | | | | | Some systems will retry their boot sequence in the event of a boot failure. On these systems, the second and subsequent boot attempts will fail to initialise the Hermon HCA. Fix by resetting the HCA during probe(). This incurs a one-second cost, but there seems to be no viable alternative. Originally-fixed-by: Itay Gazit <itaygazit@gmail.com>
* [hermon] Reduce the RC ACK timeoutMichael Brown2009-08-101-1/+1
| | | | | | | | The ACK timeout determines how long we take to notice a failed Reliable Connection. Reducing it from the arbitrary value of 19 down to 14 reduces the individual ACK timeout from around 2.1s to 67ms; this in turn reduces the time to tear down and re-establish a broken SRP session from around 30s to around 1s.
