2010-12-10bonding: add the debugfs facility to the bonding driverTaku Izumi
This patch provides the debugfs facility to the bonding driver. The "bonding" directory is created in the debugfs root and directories of each bonding interface (like bond0, bond1...) are created in that. # mount -t debugfs none /sys/kernel/debug # ls /sys/kernel/debug/bonding bond0 bond1 Signed-off-by: Taku Izumi <izumi.taku@jp.fujitsu.com> Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.

2010-12-10vxge: hotplug stallJon Mason
When hot-unplugging a vxge adapter while running, the driver's remove routine prints warning and then stalls the calling thread. This is due to vxge_remove calling vxge_device_unregister to unregister the netdev before calling flush_scheduled_work clear any pending work. Swapping the order of these two functions resolves the issue. Signed-off-by: Jon Mason <jon.mason@exar.com> Signed-off-by: Ram Vepa <ram.vepa@exar.com> Signed-off-by: David S.

2010-12-10vxge: fix crash of VF when unloading PFJon Mason
Calling pci_disable_sriov when unloading a SR-IOV physical function driver from a host when a guest is using a virtual function from that device can cause a host crash or VM crash. The crash is caused by the virtual config space no longer being present when PF is removed (due to the pci_disable_sriov). This can be avoided by not calling pci_disable_sriov to disable the PCI space when shutting down the PF. Each function in the X3100 operates independently and in this case will operate properly in the absence of the PF. Also, added improved logic in the detection of SR-IOV initialization.

2010-12-07sfc: Fix crash in legacy onterrupt handler during ring reallocationBen Hutchings
If we are using a legacy interrupt, our IRQ may be shared and our interrupt handler may be called even though interrupts are disabled on the NIC. When we change ring sizes, we reallocate the event queue and the interrupt handler may use an invalid pointer when called for another device's interrupt. Maintain a legacy_irq_enabled flag and test that at the top of the interrupt handler. Note that this problem results from the need to work around broken INT_ISR0 reads, and does not affect the legacy interrupt handler for Falcon A1.

2010-12-06sfc: Use TX push whenever adding descriptors to an empty queueBen Hutchings
Whenever we add DMA descriptors to a TX ring and update the ring pointer, the TX DMA engine must first read the new DMA descriptors and then start reading packet data. However, all released Solarflare 10G controllers have a 'TX push' feature that allows us to reduce latency by writing the first new DMA descriptor along with the pointer update. This is only useful when the queue is empty. The hardware should ignore the pushed descriptor if the queue is not empty, but this check is buggy, so we must do it in software. In order to tell whether a TX queue is empty, we need to compare the previous transmission count (write_count) and completion count (read_count). However, if we do that every time we update the ring pointer then read_count may ping-pong between the caches of two CPUs running the transmission and completion paths for the queue. Therefore, we split the check for an empty queue between the completion path and the transmission path: - Add an empty_read_count field representing a point at which the completion path saw the TX queue as empty. - Add an old_write_count field for use on the completion path. - On the completion path, whenever read_count reaches or passes old_write_count the TX queue may be empty. We then read write_count, set empty_read_count if read_count == write_count, and update old_write_count. - On the transmission path, we read empty_read_count. If it's set, we compare it with the value of write_count before the current set of descriptors was added. If they match, the queue really is empty and we can use TX push.
