2010-02-19iwlwifi: enable serialization of synchronous commandsReinette Chatre
Until now it was only possible to have one synchronous command running at any time. If a synchronous command is in progress when a second request arrives then the second command will fail. Create a new mutex specific for this purpose to only allow one synchronous command at a time, but enable other commands to wait instead of fail if a synchronous command is in progress.

2009-12-21iwlwifi: allocated rx page accounting cleanupZhu Yi
In iwlwifi, priv->alloc_rxb_page is used to keep track of the Rx pages allocated by the driver. This cleans up the page free routines by introducing __iwl_free_pages/iwl_free_pages so that the accounting is more accurate and less error prone. This also fixes two instances where the counter was not updated. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

2009-10-27iwlwifi: use paged RxZhu Yi
This switches the iwlwifi driver to use paged skb from linear skb for Rx buffer. So that it relieves some Rx buffer allocation pressure for the memory subsystem. Currently iwlwifi (4K for 3945) requests 8K bytes for Rx buffer. Due to the trailing skb_shared_info in the skb->data, alloc_skb() will do the next order allocation, which is 16K bytes. This is suboptimal and more likely to fail when the system is under memory usage pressure. Switching to paged Rx skb lets us allocate the RXB directly by alloc_pages(), so that only order 1 allocation is required. It also adjusts the area spin_lock (with IRQ disabled) protected in the tasklet because tasklet guarentees to run only on one CPU and the new unprotected code can be preempted by the IRQ handler. This saves us from spawning another workqueue to make skb_linearize/__pskb_pull_tail happy (which cannot be called in hard irq context). Finally, mac80211 doesn't support paged Rx yet. So we linearize the skb for all the management frames and software decryption or defragmentation required data frames before handed to mac80211. For all the other frames, we __pskb_pull_tail 64 bytes in the linear area of the skb for mac80211 to handle them properly. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.

Break down the traffic type and counter for both Tx and Rx.

2009-07-27iwlwifi: remove command callback return valueJohannes Berg
No existing callbacks use anything other than the return value 1, which means that the caller should free the reply skb, so it seems safer in terms of not introducing memory leaks to simply remove the return value and let the caller always free the skb.

2009-07-27iwlwifi: fix up command sendingJohannes Berg
The current command sending in iwlwifi is a bit of a mess: 1) there is a struct, iwl_cmd, that contains both driver and device data in a single packed structure -- this is very confusing 2) the on-stack data and the command metadata share a structure by embedding the latter in the former, which is also rather confusing because it leads to weird unions and similarly odd constructs 3) each txq always has enough space for 256 commands, even if only 32 end up being used This patch fixes these things: 1) rename iwl_cmd to iwl_device_cmd and keep track of command metadata and device command separately, in two arrays in each tx queue 2) remove the 'meta' member from iwl_host_cmd and only put in the required members 3) allocate the cmd/meta arrays separately instead of embedding them into the txq structure Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

2009-01-16iwlwifi: remove CMD_WANT_SKB flag if send_cmd_sync failureZhu Yi
In function iwl_send_cmd_sync(), if the flag CMD_WANT_SKB is set but we are not provided with a valid SKB (cmd->meta.u.skb == NULL), we need to remove the CMD_WANT_SKB flag from the TX cmd queue. Otherwise in case the cmd comes in later, it will possibly set an invalid address. Thus it causes an invalid memory access. This fixed the bug http://bugzilla.kernel.org/show_bug.cgi?id=11326.
