* ath6kl: assign Tx packet drop threshold per endpoint based on AC priorityChilam Ng2012-02-271-0/+1
| | | | | | | | | | | | | | Tx packets will begin to drop when there are multiple traffic priorities and the current traffic is not the highest priority and the remaining cookies drop below a certain number, which is fixed for all AC. It is possilbe that lower priority AC have more traffic which will consume more cookies and lock out higher priority AC from having any. Assign each endpoint (AC) with a different Tx-packet-drop threshold so lower priority AC is more likely to drop packets and the cookies become more available to higher priority AC.

* ath6kl: prioritize Tx bundling based on AC prioritiesChilam Ng2012-02-081-1/+6
| | | | | | | | | | | | | | | | | | Tx bundling is the more efficient use of SDIO bus and allows more packet transfers with fewer bus transactions, and is a way to improve overall throughput. However, Tx bundling has only 4 scatter request resources available. When there are multiple traffic streams of different priorities, it's possible that lower priority traffic may hog all the scatter requests and lock out the higher prioirty traffic from bundling. Tx bundling is now enabled per AC. When an AC do a scatter request and the remaining scatter request resources is lower than a configurable threshold, it will disable Tx bundling for all AC's of lower priorities. When an AC has Tx bundling disabled and has no Tx bundles sent in a consecutive and configurable number of packets, Tx bundling will be re-enabled for that AC.

* Add ath6kl cleaned up driverKalle Valo2011-08-091-0/+596
Last May we started working on cleaning up ath6kl driver which is currently in staging. The work has happened in a separate ath6kl-cleanup tree: http://git.kernel.org/?p=linux/kernel/git/kvalo/ath6kl-cleanup.git;a=summary After over 1100 (!) patches we have now reached a state where I would like to start discussing about pushing the driver to the wireless trees and replacing the staging driver. The driver is now a lot smaller and looks like a proper Linux driver. The size of the driver (measured with simple wc -l) dropped from 49 kLOC to 18 kLOC and the number of the .c and .h files dropped from 107 to 22. Most importantly the number of subdirectories reduced from 26 to zero :) There are two remaining checkpatch warnings in the driver which we decided to omit for now: drivers/net/wireless/ath/ath6kl/debug.c:31: WARNING: printk() should include KERN_ facility level drivers/net/wireless/ath/ath6kl/sdio.c:527: WARNING: msleep < 20ms can sleep for up to 20ms; see Documentation/timers/timers-howto.txt The driver has endian annotations for all the hardware specific structures and there are no sparse errors. Unfortunately I don't have any big endian hardware to test that right now. We have been testing the driver both on x86 and arm platforms. The code is also compiled with sparc and parisc cross compilers. Notable missing features compared to the current staging driver are: o HCI over SDIO support o nl80211 testmode o firmware logging o suspend support Testmode, firmware logging and suspend support will be added soon. HCI over SDIO support will be more difficult as the HCI driver needs to share code with the wifi driver. This is something we need to research more. Also I want to point out the changes I did for signed endian support. As I wasn't able to find any support for signed endian annotations I decided to follow what NTFS has done and added my own. Grep for sle16 and sle32, especially from wmi.h. Various people have been working on the cleanup, the hall of fame based on number of patches is: 543 Vasanthakumar Thiagarajan 403 Raja Mani 252 Kalle Valo 16 Vivek Natarajan 12 Suraj Sumangala 3 Joe Perches 2 Jouni Malinen Signed-off-by: Vasanthakumar Thiagarajan <vthiagar@qca.qualcomm.com> Signed-off-by: Raja Mani <rmani@qca.qualcomm.com> Signed-off-by: Vivek Natarajan <nataraja@qca.qualcomm.com> Signed-off-by: Suraj Sumangala <surajs@qca.qualcomm.com> Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
