2007-05-31PCI: disable MSI by default on systems with Serverworks HT1000 chipsAndy Gospodarek
I've been seeing lots of messages like these: eth0: No interrupt was generated using MSI, switching to INTx mode. Please report this failure to the PCI maintainer and include system chipset information. On several systems that use the following Severworks HT1000 (also sometimes labeled as a Broadcom chipset as well) bridge chips. It doesn't appear MSI works well (if at all) on these systems.

2007-05-31ieee1394: sbp2: offer SAM-conforming target port ID in sysfsStefan Richter
With "modprobe sbp2 long_ieee1394_id=y", the format of /sys/bus/scsi/devices/*:*:*:*/ieee1394_id is changed from e.g. 0001041010004beb:0:0 to 0001041010004beb:00042c:0000. The longer format fully conforms to object identifier sizes as per SAM(-2...4) and reflects what the SAM target port identifier is meant to contain: A Discovery ID allegedly specified by ISO/IEC 13213:1994 --- however there is no such thing; the authors of SAM probably meant Directory ID). Especially target nodes with multiple dynamically added targets may use Directory IDs to persistently identify target ports. The new format is independent of implementation details of nodemgr. Thus the same ieee1394_id attribute format can be implemented in the new firewire stack. The ieee1394_id is typically used to create persistently named links in /dev/disk/by-id.

2007-05-31ACPI: thinkpad-acpi: do not use named sysfs groupsHenrique de Moraes Holschuh
The initial version of the thinkpad-acpi sysfs interface (not yet released in any stable mainline kernel) made liberal use of named sysfs groups, in order to get the attributes more organized. This proved to be a really bad design decision. Maybe if attribute groups were as flexible as a real directory, and if binary attributes were not second-class citizens, the idea of subdirs and named groups would not have been so bad. This patch makes all the thinkpad-acpi sysfs groups anonymous (thus removing the subdirs), adds the former group names as a prefix (so that hotkey/enable becomes hotkey_enable for example), and updates the documentation. These changes will make the thinkpad-acpi sysfs ABI a lot easier to maintain. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Len Brown <len.brown@intel.com>

This restores the previously removed netif_poll_enable call in e1000_open. It's needed on all but the first call to e1000_open for a NIC as e1000_close always calls netif_poll_disable. netif_poll_enable can only be called safely if no polls have been scheduled. This should be the case as long as we don't enter our IRQ handler. In order to guarantee this we explicitly disable IRQs as early as possible when we're probing the NIC.

2007-05-30ACPI: Make _OSI(Linux) a special caseLen Brown
_OSI("Linux") is like _OS("Linux"), it is ill-defined and virtually no BIOS vendors test interaction with it. As a result, it can do more damage than good because it causes the BIOS to follow un-tested paths. Recently, several machines have turned up that erroneously test this string in a way which causes them to _not_ test other compatibility strings, including the ZI9 and Toshiba. So it appears that this bad code has made it into a BIOS vendor's reference BIOS. Linux has no choice but to stop advertising compatibility with _OSI string "Linux" - as there are an unbounded number of possible incompatibilities going forward. But some BIOSes have already shipped which do use it for things like conditionally re-enabling video on resume from S3. (Too bad they didn't do that unconditionally) Add special case code for _OSI(Linux) Squawk to dmesg if _OSI(Linux) is requested Add DMI list both to enable and disable _OSI(Linux) But for now, keep the default enabled via #define OSI_LINUX_ENABLED. http://bugzilla.kernel.org/show_bug.cgi?id=7787 Signed-off-by: Len Brown <len.brown@intel.com>

2007-05-29IPoIB/cm: Fix performance regression on MellanoxMichael S. Tsirkin
commit 518b1646 ("IPoIB/cm: Fix SRQ WR leak") introduced a severe performance regression on Mellanox cards, because keeping a QP in the error state for extended periods of time moves hardware to the slow path (until the QP is destroyed). For example, MPI latency goes from ~3 usecs to ~7 usecs. Fix this by posting a send WR on one of the QPs that are being flushed, instead of using a separate drain QP that is kept in the error state. This fixes bug <https://bugs.openfabrics.org/show_bug.cgi?id=636>, reported and bisected by Scott Weitzenkamp at Cisco and debugged by Sasha Mikheev at Voltaire. Signed-off-by: Michael S.

But for Tavor hardware, send CQEs with error can be chained together even if the RQ is part of SRQ, so we may miss some CQEs. Fix by following the WQE chain for all send CQEs even for non-SRQ QPs.
