2011-11-15iwlegacy: rename iwl to ilStanislaw Gruszka
iwl_legacy prefix result in long function names, what cause that we have frequent line split and not readable code. Also iwl_foo symbols are duplicated in iwlwifi driver, what is annoying when editing kernel tree with cscope. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com>

2011-09-21iwlegacy: do not use interruptible waitsStanislaw Gruszka
iwlegacy version of fix: commit effd4d9aece9184f526e6556786a94d335e38b71 Author: Johannes Berg <johannes.berg@intel.com> Date: Thu Sep 15 11:46:52 2011 -0700 iwlagn: do not use interruptible waits Since the dawn of its time, iwlwifi has used interruptible waits to wait for synchronous commands and firmware loading. This leads to "interesting" bugs, because it can't actually handle the interruptions; for example when a command sending is interrupted it will assume the command completed fully, and then leave it pending, which leads to all kinds of trouble when the command finishes later. Since there's no easy way to gracefully deal with interruptions, fix the driver to not use interruptible waits. This at least fixes the error iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD' I have seen in P2P testing, but it is likely that there are other errors caused by this.

2011-09-21iwlegacy: fix command queue timeoutStanislaw Gruszka
iwlegacy version of fix: commit 282cdb325aea4ebbc42ce753b47cc96145eb54bc Author: Johannes Berg <johannes.berg@intel.com> Date: Mon Sep 12 12:09:10 2011 -0700 iwlagn: fix command queue timeout If the command queue is constantly busy, which can happen in P2P, the hangcheck timer will frequently find a command in it and will eventually reset the device because nothing sets the timestamp for this queue when commands are processed. Fix this by setting the timestamp when a command completes. iwlegacy does not support P2P, but this patch fix possible unneeded hardware resets, hence is needed.

2011-04-29iwlegacy: fix enqueue hcmd race conditionsStanislaw Gruszka
We mark command as huge by using meta->flags from other (non huge) command, but flags can be possibly overridden, when non huge command is enqueued, what can lead to: WARNING: at lib/dma-debug.c:696 dma_debug_device_change+0x1a3/0x1f0() DMA-API: device driver has pending DMA allocations while released from device [count=1] To fix introduce additional CMD_MAPPED to mark command as mapped and serialize iwl_enqueue_hcmd() with iwl_tx_cmd_complete() using hcmd_lock. Serialization will also fix possible race conditions, because q->read_ptr, q->write_ptr are modified/used in parallel. Do not change callback, I did (and fixed) that mistake in iwlagn.

2011-02-21iwlwifi: split the drivers for agn and legacy devices 3945/4965Wey-Yi Guy
Intel WiFi devices 3945 and 4965 now have their own driver in the folder drivers/net/wireless/iwlegacy Add support to build these drivers independently of the driver for AGN devices. Selecting the 3945 builds iwl3945.ko and iwl_legacy.ko, and selecting the 4965 builds iwl4965.ko and iwl_legacy.ko. iwl-legacy.ko contains code shared between both devices. The 3945 is an ABG/BG device, with no support for 802.11n. The 4965 is a 2x3 ABGN device.
