Rodriguez Date: Tue, 3 Feb 2009 17:12:16 -0800 Subject: [ath9k-devel] [RFC] Serialization of writes Message-ID: <20090204011216.GA8220@tesla> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ath9k-devel@lists.ath9k.org Some devices requires serialization of writes, this is required for AR5416 and AR9280 PCI devices. This was not implemented in ath9k though. Here's an attempt, but I have no way of testing this as I haven't had issues with my systems or cards. I am not sure if this should fix some of the current issues being reported but it may help. Those who have issues on SMP systems with hostapd locking up -- please give this a whirl, let me know if it helps. This has 3 patches in 1 file, the one that counts it the third one but just apply it all together, 'patch -p1 serialize.patch' ( for compat-wireless users or testers) or 'git am serialize.patch' for git users. Feedback on results is appreciated. http://www.kernel.org/pub/linux/kernel/people/mcgrof/patches/ath9k/tmp/serialize.patch Luis
