| | * virtio_net: avoid (most) NETDEV_TX_BUSY by stopping queue early.Rusty Russell2009-09-241-24/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now we can tell the theoretical capacity remaining in the output queue, virtio_net can waste entries by stopping the queue early. It doesn't work in the case of indirect buffers and kmalloc failure, but that's rare (we could drop the packet in that case, but other drivers return TX_BUSY for similar reasons). For the record, I think this patch reflects poorly on the linux network API. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Dinesh Subhraveti <dineshs@us.ibm.com>

| | * virtio_net: don't free buffers in xmit ringRusty Russell2009-09-241-59/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The virtio_net driver is complicated by the two methods of freeing old xmit buffers (in addition to freeing old ones at the start of the xmit path). The original code used a 1/10 second timer attached to xmit_free(), reset on every xmit. Before we orphaned skbs on xmit, the transmitting userspace could block with a full socket until the timer fired, the skb destructor was called, and they were re-woken. So we added the VIRTIO_F_NOTIFY_ON_EMPTY feature: supporting devices send an interrupt (even if normally suppressed) on an empty xmit ring which makes us schedule xmit_tasklet(). This was a benchmark win. Unfortunately, VIRTIO_F_NOTIFY_ON_EMPTY makes quite a lot of work: a host which is faster than the guest will fire the interrupt every xmit packet (slowing the guest down further). Attempting mitigation in the host adds overhead of userspace timers (possibly with the additional pain of signals), and risks increasing latency anyway if you get it wrong. In practice, this effect was masked by benchmarks which take advantage of GSO (with its inherent transmit batching), but it's still there. Now we orphan xmitted skbs, the pressure is off: remove both paths and no longer request VIRTIO_F_NOTIFY_ON_EMPTY. Note that the current QEMU will notify us even if we don't negotiate this feature (legal, but suboptimal); a patch is outstanding to improve that. Move the skb_orphan/nf_reset to after we've done the send and notified the other end, for a slight optimization.

| | * virtio_net: return NETDEV_TX_BUSY instead of queueing an extra skb.Rusty Russell2009-09-241-36/+10Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This effectively reverts 99ffc696d10b28580fe93441d627cf290ac4484c "virtio: wean net driver off NETDEV_TX_BUSY". The complexity of queuing an skb (setting a tasklet to re-xmit) is questionable, especially once we get rid of the other reason for the tasklet in the next patch. If the skb won't fit in the tx queue, just return NETDEV_TX_BUSY. This is frowned upon, so a followup patch uses a more complex solution.

| | * virtio_net: skb_orphan() and nf_reset() in xmit path.Rusty Russell2009-09-241-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The complex transmit free logic was introduced to avoid hangs on removing the ip_conntrack module and also because drivers aren't generally supposed to keep stale skbs for unbounded times. After some debate, it was decided that while doing skb_orphan() generally is a rat's nest, we can do it in this driver. Following patches take advantage of this.

Though, there are few other issues with suspend/resume in this driver. The intention of calling free_irq() in suspend() was to avoid any possible spurious interrupts (see commit 5b039e681b8c5f30aac9cc04385 "3c59x PM fixes"). But, - On resume, the driver was requesting IRQ just after pci_set_master(), but before vortex_up() (which actually resets 3c59x chips). - Issuing free_irq() on a shared IRQ doesn't guarantee that a buggy HW won't trigger spurious interrupts in another driver that requested the same interrupt. So, if we want to protect from unexpected interrupts, then on suspend we should issue disable_irq(), not free_irq(). Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S.

When we are in the tasklet we cannot sleep and thus attempt atomic skb allocations. It is generally not a big problem if this fails since iwl_rx_allocate is always followed by a call to iwl_rx_queue_restock which will queue the work to replenish the buffers at a time when sleeping is allowed. We thus add the __GFP_NOWARN to the skb allocation in iwl_rx_allocate to reduce the noise if such an allocation fails while we still have enough buffers. We do maintain the warning and the error message when we are low on buffers to communicate to the user that there is a potential problem with memory availability on system This addresses issue reported upstream in thread "iwlagn: order 2 page allocation failures" in http://thread.gmane.org/gmane.linux.kernel.wireless.general/39187 Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Acked-by: Mel Gorman <mel@csn.ul.ie> Signed-off-by: John W.

The fix involved changing an async command to synchronous. Unfortunately this was inside a spinlock section in which we cannot sleep. Modify the sending of the command back to async. This causes the mac80211 error "mac80211-phy0: failed to remove key (0, ff:ff:ff:ff:ff:ff) from hardware (-16)." to return. This error is not serious since this occurs during interface down and the keys will be cleared anyway when ucode is unloaded. Having this error message is thus less serious than a potential deadlock introduced when sleeping while holding a spinlock. We will have to find another fix for that error.

According to the spec, this is the wrong behaviour for the LP PHY (see: http://bcm-v4.sipsolutions.net/802.11/PHY/Anacore ) While no problems on the x86 plattform where seen, this leads to a crash on the BCM5354 SoC (MIPS 32 LE plattform).
