* e1000: allow option to limit number of descriptors down to 48 per ringAlexander Duyck2010-07-191-2/+2
| | | | | | | | | | | | This change makes it possible to limit the number of descriptors down to 48 per ring. The reason for this change is to address a variation on hardware errata 10 for 82546GB in which descriptors will be lost if more than 32 descriptors are fetched and the PCI-X MRBC is 512.

* e1000: do not modify tx_queue_len on link speed changeEmil Tantilov2010-03-271-1/+0
| | | | | | | | | | | | | | | | | Previously the driver tweaked txqueuelen to avoid false Tx hang reports seen at half duplex. This had the effect of overriding user set values on link change/reset.

* e1000: enhance frame fragment detectionJesse Brandeburg2010-01-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Originally From: Neil Horman <nhorman@tuxdriver.com> Modified by: Jesse Brandeburg <jesse.brandeburg@intel.com> Hey all- A security discussion was recently given: http://events.ccc.de/congress/2009/Fahrplan//events/3596.en.html And a patch that I submitted awhile back was brought up. Apparently some of their testing revealed that they were able to force a buffer fragment in e1000 in which the trailing fragment was greater than 4 bytes. As a result the fragment check I introduced failed to detect the fragement and a partial invalid frame was passed up into the network stack. I've written this patch to correct it. I'm in the process of testing it now, but it makes good logical sense to me. Effectively it maintains a per-adapter state variable which detects a non-EOP frame, and discards it and subsequent non-EOP frames leading up to _and_ _including_ the next positive-EOP frame (as it is by definition the last fragment). This should prevent any and all partial frames from entering the network stack from e1000.

* e1000: implement jumbo receive with partial descriptorsJesse Brandeburg2009-07-061-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is code extremely similar to what is committed in e1000e already. e1000 will no longer request 32kB slab buffers to support jumbo frames on PCI/PCI-X adapters. This will significantly reduce the likelyhood of order:3 allocation failures. This new code adds support for using pages as receive buffers, and the driver will chain multiple pages together to build a jumbo frame for OS consumption. The hardware takes a power of two buffer size and will dump as much data as it can receive into 1 or more buffers. The benefits of applying this are 1) stop akpm's dissing :-) of this lame e1000 behavior [1] 2) more efficient memory allocation (half) when using jumbo frames, which will also allow for much better socket utilization with jumbos since the socket is charged for the full allocation of each receive buffer, regardless of how much is used. 3) this was a feature request by a customer 4) copybreak for small packets < 256 bytes still applies [1] http://lkml.org/lkml/2008/7/10/68 http://article.gmane.org/gmane.linux.network/130986 Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> CC: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

* [NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger2007-10-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device. With lots of help and suggestions from Rusty Russell, Roland Dreier, Michael Chan, Jeff Garzik, and Jamal Hadi Salim.

* e1000: add dynamic itr modesJesse Brandeburg2006-12-021-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new dynamic itr algorithm, with 2 modes, and make it the default operation mode. This greatly reduces latency and increases small packet performance, at the "cost" of some CPU utilization. Bulk traffic throughput is unaffected. The driver can limit the amount of interrupts per second that the adapter will generate for incoming packets. It does this by writing a value to the adapter that is based on the maximum amount of interrupts that the adapter will generate per second. Setting InterruptThrottleRate to a value greater or equal to 100 will program the adapter to send out a maximum of that many interrupts per second, even if more packets have come in. This reduces interrupt load on the system and can lower CPU utilization under heavy load, but will increase latency as packets are not processed as quickly. The default behaviour of the driver previously assumed a static InterruptThrottleRate value of 8000, providing a good fallback value for all traffic types,but lacking in small packet performance and latency. The hardware can handle many more small packets per second however, and for this reason an adaptive interrupt moderation algorithm was implemented. Since 7.3.x, the driver has two adaptive modes (setting 1 or 3) in which it dynamically adjusts the InterruptThrottleRate value based on the traffic that it receives. After determining the type of incoming traffic in the last timeframe, it will adjust the InterruptThrottleRate to an appropriate value for that traffic. The algorithm classifies the incoming traffic every interval into classes. Once the class is determined, the InterruptThrottleRate value is adjusted to suit that traffic type the best. There are three classes defined: "Bulk traffic", for large amounts of packets of normal size; "Low latency", for small amounts of traffic and/or a significant percentage of small packets; and "Lowest latency", for almost completely small packets or minimal traffic. In dynamic conservative mode, the InterruptThrottleRate value is set to 4000 for traffic that falls in class "Bulk traffic". If traffic falls in the "Low latency" or "Lowest latency" class, the InterruptThrottleRate is increased stepwise to 20000. This default mode is suitable for most applications. For situations where low latency is vital such as cluster or grid computing, the algorithm can reduce latency even more when InterruptThrottleRate is set to mode 1. In this mode, which operates the same as mode 3, the InterruptThrottleRate will be increased stepwise to 70000 for traffic in class "Lowest latency". Setting InterruptThrottleRate to 0 turns off any interrupt moderation and may improve small packet latency, but is generally not suitable for bulk throughput traffic.

| * e1000: rework driver hardware reset lockingAuke Kok2006-06-271-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After studying the driver mac reset code it was found that there were multiple race conditions possible to reset the unit twice or bring it e1000_up() double. This fixes all occurences where the driver needs to reset the mac. We also remove irq requesting/releasing into _open and _close so that while the device is _up we will never touch the irq's. This fixes the double free irq bug that people saw. To make sure that the watchdog task doesn't cause another race we let it run as a non-scheduled task.

* e1000: Buffer optimizations for small MTUAuke Kok2006-04-141-0/+2
| | | | | | | | | | | | | | | | | | | | Remove multi-descriptor support from legacy recieve path Add memory usage efficiency by using more correct size descriptors for small MTU sizes and optimize using LPE for <= 1522 byte frame sizes An extra performance fix that effected our TCP window size growth as a receiver. Set our initial buffer to be 128 bytes instead of 256 to prevent over-socket charge when truesize is computed in the stack. old way: truesize = 256 + l1 = 256 + 1460 = 1716 new way: truesize = 128 + l1 = 128 + 1460 = 1588 The magic value that we can't cross is 1648.
