2010-05-05e1000/e1000e: implement a simple interrupt moderationJesse Brandeburg
Back before e1000-7.3.20, the e1000 driver had a simple algorithm that managed interrupt moderation. The driver was updated in 7.3.20 to have the new "adaptive" interrupt moderation but we have customer requests to redeploy the old way as an option. This patch adds the old functionality back. The new functionality can be enabled via module parameter or at runtime via ethtool. Module parameter: (InterruptThrottleRate=4) to use this new moderation method. Ethtool method: ethtool -C ethX rx-usecs 4 Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

2010-04-27e1000: Use netdev_<level>, pr_<level> and dev_<level>Emil Tantilov
This patch is an alternative to similar patch provided by Joe Perches. Substitute DPRINTK macro for e_<level> that uses netdev_<level> and dev_<level> similar to e1000e. - Convert printk to pr_<level> where applicable. - Use common #define pr_fmt for the driver. - Use dev_<level> for displaying text in parts of the driver where the interface name is not assigned (like e1000_param.c). - Better align test with the new macros.

this patch is the first in a series of clean up patches for e1000 to drop unused code, and update the driver to kernel spec, and then, to update the driver to have all available bug fixes. Call it the e1000 weight loss plan.

2008-08-27e1000: fix stack sizeLinus Torvalds
Here's the patch. It shrinks the stack from 1152 bytes to 192 bytes (the first version, that only did the e1000_option part, got it down to 600 bytes). About half comes from not using multiple "e1000_option" structures, the other half comes from turning the "e1000_opt_list[]" arrays into "static const" instead, so that gcc doesn't copy them onto the stack.

2006-12-02e1000: add dynamic itr modesJesse Brandeburg
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.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
