* [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
| | | | | | | This reverts commit 15c1200 ("[hermon] Work around missing mport support in current BOFM implementations"). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [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>

* [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>

* [arbel] Optimise ICM layout to reduce overall memory usageMichael Brown2010-09-172-75/+136

| | | | | | | | | | | The current method for ICM allocation exactly matches the addresses chosen by the old Etherboot driver, but does not match the specification.

* [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>
