This is a note to let you know that I have just added a patch titled b43: N-PHY: increase initial value of "mind" in RSSI to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 832b8f35d56a752b6e8dc3c71b6f283b7f4140cc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= <zajec5@gmail.com> Date: Tue, 19 Mar 2013 07:52:48 +0100 Subject: [PATCH] b43: N-PHY: increase initial value of "mind" in RSSI calibration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit e67dd874e60529dbd2e8232babb1e23479ba2ffa upstream. We're using "mind" variable to find the VCM that got the best polling results. For each VCM we calculte "currd" which is compared to the "mind". For PHY rev3+ "currd" gets values around 14k-40k. Looking for a value smaller than 40 makes no sense, so increase the initial value. This fixes a regression introduced in 3.4 by commit: e0c9a0219a8f542e3946fe972a68aacf8c3f906c (my BCM4322 performance dropped from 18,4Mb/s to 9,26Mb/s) Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: John W.
