From 262eb9b2237ecee047451a636e799ea1572b685a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 13 Jul 2011 10:39:09 +0200 Subject: cfg80211: split wext compatibility to separate header A lot of drivers erroneously use wext constants and don't notice since cfg80211.h includes them. Make this more split up so drivers needing wext compatibility from cfg80211 need to explicitly include that from cfg80211-wext.h. Signed-off-by: Johannes Berg Signed-off-by: John W.

To simplify the code, always reserve it, we could continue using it on older uCode images but that'd be rather complicated.

We could keep all the new code private, but that causes plenty of problems and sometimes we can give a pre-release version of firmware to people who need to test. However, when we just bump the API version, the driver will warn everybody that their firmware is outdated, when in fact it isn't. (Currently our case for this doesn't really change the API but bumping the API version is necessary because the firmware isn't fully backward compatible) In order to handle this in the future, add a new "api_ok" version; only below this will the driver warn that the uCode is too old.

In order to give a much better approximation of the real channel noise, add the difference between the measured noise floor and the nominal chip specific noise floor to the default minimum channel noise value, which is currently used to calculate the signal strength from the RSSI value. This may not be 100% accurate, but it's much better than what's there before. Signed-off-by: Felix Fietkau Signed-off-by: John W.

The work has happened in a separate ath6kl-cleanup tree: http://git.kernel.org/?p=linux/kernel/git/kvalo/ath6kl-cleanup.git;a=summary After over 1100 (!) patches we have now reached a state where I would like to start discussing about pushing the driver to the wireless trees and replacing the staging driver. The driver is now a lot smaller and looks like a proper Linux driver. The size of the driver (measured with simple wc -l) dropped from 49 kLOC to 18 kLOC and the number of the .c and .h files dropped from 107 to 22. Most importantly the number of subdirectories reduced from 26 to zero :) There are two remaining checkpatch warnings in the driver which we decided to omit for now: drivers/net/wireless/ath/ath6kl/debug.c:31: WARNING: printk() should include KERN_ facility level drivers/net/wireless/ath/ath6kl/sdio.c:527: WARNING: msleep < 20ms can sleep for up to 20ms; see Documentation/timers/timers-howto.txt The driver has endian annotations for all the hardware specific structures and there are no sparse errors. Unfortunately I don't have any big endian hardware to test that right now. We have been testing the driver both on x86 and arm platforms. The code is also compiled with sparc and parisc cross compilers. Notable missing features compared to the current staging driver are: o HCI over SDIO support o nl80211 testmode o firmware logging o suspend support Testmode, firmware logging and suspend support will be added soon. HCI over SDIO support will be more difficult as the HCI driver needs to share code with the wifi driver. This is something we need to research more. Also I want to point out the changes I did for signed endian support. As I wasn't able to find any support for signed endian annotations I decided to follow what NTFS has done and added my own. Grep for sle16 and sle32, especially from wmi.h. Various people have been working on the cleanup, the hall of fame based on number of patches is: 543 Vasanthakumar Thiagarajan 403 Raja Mani 252 Kalle Valo 16 Vivek Natarajan 12 Suraj Sumangala 3 Joe Perches 2 Jouni Malinen Signed-off-by: Vasanthakumar Thiagarajan Signed-off-by: Raja Mani Signed-off-by: Vivek Natarajan Signed-off-by: Suraj Sumangala Signed-off-by: Joe Perches Signed-off-by: Jouni Malinen Signed-off-by: Kalle Valo --- drivers/net/wireless/ath/Kconfig | 1 + drivers/net/wireless/ath/Makefile | 1 + drivers/net/wireless/ath/ath6kl/Kconfig | 17 + drivers/net/wireless/ath/ath6kl/Makefile | 35 + drivers/net/wireless/ath/ath6kl/bmi.c | 692 +++++++ drivers/net/wireless/ath/ath6kl/bmi.h | 250 +++ drivers/net/wireless/ath/ath6kl/cfg80211.c | 1538 ++++++++++++++++ drivers/net/wireless/ath/ath6kl/cfg80211.h | 39 + drivers/net/wireless/ath/ath6kl/common.h | 183 ++ drivers/net/wireless/ath/ath6kl/core.h | 546 ++++++ drivers/net/wireless/ath/ath6kl/debug.c | 150 ++ drivers/net/wireless/ath/ath6kl/debug.h | 104 ++ drivers/net/wireless/ath/ath6kl/hif-ops.h | 67 + drivers/net/wireless/ath/ath6kl/hif.h | 216 +++ drivers/net/wireless/ath/ath6kl/htc.c | 2466 +++++++++++++++++++++++++ drivers/net/wireless/ath/ath6kl/htc.h | 596 ++++++ drivers/net/wireless/ath/ath6kl/htc_hif.c | 811 ++++++++ drivers/net/wireless/ath/ath6kl/htc_hif.h | 113 ++ drivers/net/wireless/ath/ath6kl/init.c | 1293 +++++++++++++ drivers/net/wireless/ath/ath6kl/main.c | 1337 ++++++++++++++ drivers/net/wireless/ath/ath6kl/node.c | 238 +++ drivers/net/wireless/ath/ath6kl/sdio.c | 853 +++++++++ drivers/net/wireless/ath/ath6kl/target.h | 331 ++++ drivers/net/wireless/ath/ath6kl/txrx.c | 1452 +++++++++++++++ drivers/net/wireless/ath/ath6kl/wmi.c | 2762 ++++++++++++++++++++++++++++ drivers/net/wireless/ath/ath6kl/wmi.h | 2024 ++++++++++++++++++++ 26 files changed, 18115 insertions(+) create mode 100644 drivers/net/wireless/ath/ath6kl/Kconfig create mode 100644 drivers/net/wireless/ath/ath6kl/Makefile create mode 100644 drivers/net/wireless/ath/ath6kl/bmi.c create mode 100644 drivers/net/wireless/ath/ath6kl/bmi.h create mode 100644 drivers/net/wireless/ath/ath6kl/cfg80211.c create mode 100644 drivers/net/wireless/ath/ath6kl/cfg80211.h create mode 100644 drivers/net/wireless/ath/ath6kl/common.h create mode 100644 drivers/net/wireless/ath/ath6kl/core.h create mode 100644 drivers/net/wireless/ath/ath6kl/debug.c create mode 100644 drivers/net/wireless/ath/ath6kl/debug.h create mode 100644 drivers/net/wireless/ath/ath6kl/hif-ops.h create mode 100644 drivers/net/wireless/ath/ath6kl/hif.h create mode 100644 drivers/net/wireless/ath/ath6kl/htc.c create mode 100644 drivers/net/wireless/ath/ath6kl/htc.h create mode 100644 drivers/net/wireless/ath/ath6kl/htc_hif.c create mode 100644 drivers/net/wireless/ath/ath6kl/htc_hif.h create mode 100644 drivers/net/wireless/ath/ath6kl/init.c create mode 100644 drivers/net/wireless/ath/ath6kl/main.c create mode 100644 drivers/net/wireless/ath/ath6kl/node.c create mode 100644 drivers/net/wireless/ath/ath6kl/sdio.c create mode 100644 drivers/net/wireless/ath/ath6kl/target.h create mode 100644 drivers/net/wireless/ath/ath6kl/txrx.c create mode 100644 drivers/net/wireless/ath/ath6kl/wmi.c create mode 100644 drivers/net/wireless/ath/ath6kl/wmi.h (limited to 'drivers/net') diff --git a/drivers/net/wireless/ath/Kconfig b/drivers/net/wireless/ath/Kconfig index d1b23067619f..073548836413 100644 --- a/drivers/net/wireless/ath/Kconfig +++ b/drivers/net/wireless/ath/Kconfig @@ -25,5 +25,6 @@ config ATH_DEBUG source "drivers/net/wireless/ath/ath5k/Kconfig" source "drivers/net/wireless/ath/ath9k/Kconfig" source "drivers/net/wireless/ath/carl9170/Kconfig" +source "drivers/net/wireless/ath/ath6kl/Kconfig" endif diff --git a/drivers/net/wireless/ath/Makefile b/drivers/net/wireless/ath/Makefile index 0e8f528c81c0..d1214696a35b 100644 --- a/drivers/net/wireless/ath/Makefile +++ b/drivers/net/wireless/ath/Makefile @@ -1,6 +1,7 @@ obj-$(CONFIG_ATH5K) += ath5k/ obj-$(CONFIG_ATH9K_HW) += ath9k/ obj-$(CONFIG_CARL9170) += carl9170/ +obj-$(CONFIG_ATH6KL) += ath6kl/ obj-$(CONFIG_ATH_COMMON) += ath.o diff --git a/drivers/net/wireless/ath/ath6kl/Kconfig b/drivers/net/wireless/ath/ath6kl/Kconfig new file mode 100644 index 000000000000..fc9f69c1f945 --- /dev/null +++ b/drivers/net/wireless/ath/ath6kl/Kconfig @@ -0,0 +1,17 @@ +config ATH6KL + tristate "Atheros ath6kl support" + depends on MMC + depends on CFG80211 + select WIRELESS_EXT + select WEXT_PRIV + ---help--- + This module adds support for wireless adapters based on + Atheros AR6003 chipset running over SDIO.

This is more like a workaround than a proper fix, but as the stall is so severe the workaround is justified. With a dual band card this increases scan time when connected from 1.9s to 4.4s.

Fix the function not to iterate nodes when the scan is aborted. The nodes are already freed when the module is being unloaded. This patch removes the null check entirely as the wmi structure is not accessed anymore during module unload. Also fix a bug where the status was checked as a bitfield with '&' operator. But it's not a bitfield, just a regular error code. This is a port of my patch from ath6kl staging with the same title.

The reason behind this, after issuing the connect command to the chip, the chip is sending disconnect event and then immediately one connect event to the host in some random cases. The host driver resets all states (including cfg80211 state machine) when it receives disconnect event from the chip. But, still the host driver reports the next received connect event to cfg80211, at that time cfg80211 SME state would have been in IDLE state, which was causing the below kernel crash.

No commands can be run while the interface is down, so the ndo_dev_stop routine now directly does all necessary work (including asking the device to disconnect from the network and disabling multicast functionality) directly. power_save and power_restore hooks are added meaning that card drivers can take steps to turn the device off when the interface is down. The MAC address can now only be changed when all interfaces are down; the new address will be programmed when an interface gets brought up. This matches mac80211 behaviour. Also, some small cleanups/simplifications were made in the surrounding device handling logic. Signed-off-by: Daniel Drake Signed-off-by: John W.

However, on SMP systems the tasklet might still be scheduled on another CPU. Instead, use tasklet_kill to ensure that all scheduled tasklets are finished before returning from toggle_irq. Furthermore, it was possible that a tasklet reenabled its interrupt even though interrupts have been disabled already. Fix this by checking the DEVICE_STATE_ENABLED_RADIO flag before reenabling single interrupts during tasklet processing. While at it also enable/kill the TBTT and PRETBTT tasklets in the toggle_irq callback and only use tasklet_kill in stop_queue to wait for a currently scheduled beacon update before returning.
