2011-02-18ath5k: Correct channel setting for AR2317 chipNikolay Ledovskikh1-0/+1
Correct channel setting function must be used for AR2317. When I tested ahb patch on bullet2 all seemed to work fine, but it couldn't connect another host (using ibss for example). During an analysis I observed that it's transmitting on another channel. I looked into madwifi code and understood that the problem is in channel setting function. So atheros RF2317 not fully handled in the current ath5k version and must be patched.

The DMA latency issue is observed only in Intel pinetrail platforms but in the driver we had a default PM-QOS value of 55. This caused unnecessary power consumption and battery drain in other platforms. Remove the pm-qos thing in the driver code and address the throughput issue in Intel pinetrail platfroms in user space using any one of the scripts in below links: http://www.kernel.org/pub/linux/kernel/people/mcgrof/scripts/cpudmalatency.c http://johannes.sipsolutions.net/files/netlatency.c.txt More details can be found in the following bugzilla link: https://bugzilla.kernel.org/show_bug.cgi?id=27532 This reverts the following commits: 98c316e348bedffa730e6f1e4baeb8a3c3e0f28b 4dc3530df7c0428b41c00399a7ee8c929406d181 10598c124ecabbbfd7522f74de19b8f7d52a1bee Signed-off-by: Mohammed Shafi Shajakhan <[email protected]> Signed-off-by: John W.

Commit: "p54: enhance rssi->dBm database import" changed the way how the driver deals with the rssical data. A new data format was necessary and hence this patch. NOTE: (for users with a custom eeprom binary) I spent some time updating p54tools to support the new format too: => (git available from) http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git It now comes with a simplistic script "n800_rssi2v2.sh" which can be used to automate the conversion.

This patch fixes several shortcomings of the previous implementation. Features of the rewrite include: * handles undocumented "0x0000" word at the start of the frequency table. (Affected some early? DELL 1450 USB devices and my Symbol 5GHz miniPCI card.) * supports more than just one reference point per band. (Also needed for the Symbol card.) * ships with default values in case the eeprom data is damaged, absent or unsupported. Signed-off-by: Christian Lamparter <[email protected]> Signed-off-by: John W.

Writing beacon to device happen through multiple write command calls. zd_usb_iowrite16v uses synchronous urb call and with multiple write commands in row causes high CPU usage.

2011-02-14zd1211rw: use async urb for write commandJussi Kivilinna2-25/+142
Writing beacon to device happen through multiple write command calls. zd_usb_iowrite16v uses synchronous urb call and with multiple write commands in row causes high CPU usage. This patch makes zd_usb_iowrite16v use asynchronous urb submit within zd_usb.c. zd_usb_iowrite16v_async_start is used to initiate writing multiple commands to device using zd_usb_iowrite16v_async. Each URB is delayed and submitted to device by next zd_usb_iowrite16v_async call or by call to zd_usb_iowrite16v_async_end. URBs submitted by zd_usb_iowrite16v_async have URB_NO_INTERRUPT set and last URB send by zd_usb_iowrite16v_async_end does not. This lower CPU usage when doing writes that require multiple URBs.

zd1211rw is using usb_bulk_msg() with usb_sndbulkpipe() on interrupt endpoint. However usb_bulk_msg() internally corrects this and makes interrupt URB.

Patch fixes: https://bugzilla.redhat.com/show_bug.cgi?id=654599 Many users report very low speed problem on 3945 devices, this patch fixes problem, but only for some of them. For unknown reason, sometimes after hw scanning, device is not able to receive frames at high rate. Since plcp health check may request hw scan to "reset radio", performance problem start to be observable after update kernel to .35, where plcp check was introduced. Bug reporter confirmed that removing plcp check fixed problem for him.
