To disable bgscan, a '0' is to be written to the bgscan_interval file.

With these features user can control power consumption by adjusting various sleep/wake up related parameters. The feature has been added for testing purposes. All 5 parameters are mandatory in correct order. They have to be written to the power_params file. These are: 1) idle_period 2) no_of_pspoll 3) dtim_policy 4) tx_wakeup_policy 5) no_tx_to_wakeup Example: echo "200 1 0 1 1" > power_params Signed-off-by: Rishi Panjwani Signed-off-by: Kalle Valo --- drivers/net/wireless/ath/ath6kl/debug.c | 63 +++++++++++++++++++++++++ 1 file changed, 63 insertions(+) diff --git a/drivers/net/wireless/ath/ath6kl/debug.c b/drivers/net/wireless/ath/ath6kl/debug.c index 52149202ffb7..70ea137cc817 100644 --- a/drivers/net/wireless/ath/ath6kl/debug.c +++ b/drivers/net/wireless/ath/ath6kl/debug.c @@ -1567,6 +1567,66 @@ static const struct file_operations fops_listen_int = { .llseek = default_llseek, }; +static ssize_t ath6kl_power_params_write(struct file *file, + const char __user *user_buf, + size_t count, loff_t *ppos) +{ + struct ath6kl *ar = file->private_data; + u8 buf[100]; + unsigned int len = 0; + char *sptr, *token; + u16 idle_period, ps_poll_num, dtim, + tx_wakeup, num_tx; + + len = min(count, sizeof(buf) - 1); + if (copy_from_user(buf, user_buf, len)) + return -EFAULT; + buf[len] = '\0'; + sptr = buf; + + token = strsep(&sptr, " "); + if (!token) + return -EINVAL; + if (kstrtou16(token, 0, &idle_period)) + return -EINVAL; + + token = strsep(&sptr, " "); + if (!token) + return -EINVAL; + if (kstrtou16(token, 0, &ps_poll_num)) + return -EINVAL; + + token = strsep(&sptr, " "); + if (!token) + return -EINVAL; + if (kstrtou16(token, 0, &dtim)) + return -EINVAL; + + token = strsep(&sptr, " "); + if (!token) + return -EINVAL; + if (kstrtou16(token, 0, &tx_wakeup)) + return -EINVAL; + + token = strsep(&sptr, " "); + if (!token) + return -EINVAL; + if (kstrtou16(token, 0, &num_tx)) + return -EINVAL; + + ath6kl_wmi_pmparams_cmd(ar->wmi, 0, idle_period, ps_poll_num, + dtim, tx_wakeup, num_tx, 0); + + return count; +} + +static const struct file_operations fops_power_params = { + .write = ath6kl_power_params_write, + .open = ath6kl_debugfs_open, + .owner = THIS_MODULE, + .llseek = default_llseek, +}; + int ath6kl_debug_init(struct ath6kl *ar) { ar->debug.fwlog_buf.buf = vmalloc(ATH6KL_FWLOG_SIZE); @@ -1649,6 +1709,9 @@ int ath6kl_debug_init(struct ath6kl *ar) debugfs_create_file("bgscan_interval", S_IWUSR, ar->debugfs_phy, ar, &fops_bgscan_int); + debugfs_create_file("power_params", S_IWUSR, ar->debugfs_phy, ar, + &fops_power_params); + return 0; } From f7830202c3ae934e2b978b750656626b203decb4 Mon Sep 17 00:00:00 2001 From: Sangwook Lee Date: Wed, 26 Oct 2011 16:28:38 +0100 Subject: [PATCH 075/247] ath6kl: Fix compilation error from of.h When compiling ath6kl for ARM with device tree tree compilation fails with errors like: include/linux/of.h: In function 'of_property_read_u32_array': include/linux/of.h:249:10: error: 'ENOSYS' undeclared Workaround this by including errno.h from init.c. kvalo: improved commit log Signed-off-by: Sangwook Lee Signed-off-by: Kalle Valo --- drivers/net/wireless/ath/ath6kl/init.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/net/wireless/ath/ath6kl/init.c b/drivers/net/wireless/ath/ath6kl/init.c index c638aabd417e..6e6a1413ed3d 100644 --- a/drivers/net/wireless/ath/ath6kl/init.c +++ b/drivers/net/wireless/ath/ath6kl/init.c @@ -16,6 +16,7 @@ */ #include +#include #include #include #include "core.h" From 1052261e4bba9879c1d7d519c8e8606c5d4264d5 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Thu, 27 Oct 2011 16:00:13 +0300 Subject: [PATCH 076/247] ath6kl: Report unique remain-on-channel cookie values Even though only a single concurrent remain-on-channel operation is supported, there may be two pending remain-on-channel events (one to indicate end of a canceled operation and another to indicate start of a new operation). User space won't be able to distinguish these events unless unique cookies are used. The previous behavior resulted in wpa_supplicant getting quite confused about the driver's offchannel state in various sequences and this made the P2P state machine behave incorrectly.

Also fix a bug where we were comparing firmware scan status values with kernel error codes, which is obviously wrong. This meant that ath6kl didn't detect when firmware informed about failed scans. I doubt that this fix doesn't make any difference in practise but it still needs to be fixed. This is fixed by adding an enum for the success status code and checking for that.

I was able to reproduce the problem by disabling all debug messages. So there has to be a race condition somewhere in the code and disable the functionality until the race is fixed. Now hardware is powered from the point where module is loaded until it's removed.

Also iwl_foo symbols are duplicated in iwlwifi driver, what is annoying when editing kernel tree with cscope.

The driver can then query the READ idx and - * process as many packets as possible, moving the WRITE idx forward as it - * resets the Rx queue buffers with new memory. - * - * The management in the driver is as follows: - * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.

The driver 'processed' idx is updated. - * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free - * list. If there are no allocated buffers in iwl->rxq->rx_free, the READ - * IDX is not incremented and iwl->status(RX_STALLED) is set.

All others are not encrypted, so the only way to get to this is erroneously on no-monitor AP side. Remove the special case for authentication frames to fix the AP shared key side when operating without cooked monitor interfaces -- with cooked monitor the IEEE80211_TX_INTFL_DONT_ENCRYPT also gets set, so we never get here -- an AP never encrypts auth frames. Without this patch, an AP operating in WEP mode with my no-monitor patches would erroneously encrypt all authentication frames, instead of none. Signed-off-by: Johannes Berg Signed-off-by: John W.

This code is called for each tx'ed frame and thus it makes sense to reduce its runtime. Do this by calculating the group index by this formula based on the SGI and HT40 flags as well as the stream number: idx = (HT40 * 2 * MINSTREL_MAX_STREAMS) + (SGI * MINSTREL_MAX_STREAMS) + (streams - 1) Hence, the groups are ordered by th HT40 flag first, then by the SGI flag and afterwards by the number of used streams.

This allows users to disable features such as HT, HT40, and to modify the MCS, AMPDU, and AMSDU settings for drivers that support it. The MCS, AMPDU, and AMSDU features that may be disabled are are reported in the phy-info netlink message as a mask. Attemping to disable features that are not supported will take no affect, but will not return errors. This is to aid backwards compatibility in user-space apps that may not be clever enough to deal with parsing the the capabilities mask. This patch only enables the infrastructure. An additional patch will enable the feature in mac80211. Signed-off-by: Ben Greear Signed-off-by: John W.

This implements ht-cap over-rides for mac80211 drivers. HT may be disabled, making an /a/b/g/n station act like an a/b/g station. HT40 may be disabled forcing the station to be HT20 even if the AP and local hardware support HT40. MAX-AMSDU may be disabled. AMPDU-Density may be increased. AMPDU-Factor may be decreased. This has been successfully tested with ath9k using patched wpa_supplicant and iw. Signed-off-by: Ben Greear Signed-off-by: John W.

To fix the second one, simply remove rcu_dereference() in mesh_gate_del() -- it already gets a proper pointer as indicated by the prototype (no __rcu annotation) and confirmed by the code.
