Subject: [PATCH] ath9k: Enable multi-channel properly
|
||||
|
||||
In MCC mode, currently the decision to enable
|
||||
the multi-channel state machine is done
|
||||
based on the association status if one of
|
||||
the interfaces assigned to a context is in
|
||||
station mode.
|
||||
|
||||
This allows the driver to switch to the other
|
||||
context before the current station is able to
|
||||
complete the 4-way handshake in case it is
|
||||
required and this causes problems.
|
||||
|
||||
Instead, enable multi-channel mode when the
|
||||
station moves to the authorized state. This
|
||||
disallows an early switch to the other channel.

When the current operating channel context has

do not process beacons that might be received,

since we have to wait for the station to become

Also, since the cached TSF value will be zero

initially do not rearm the timer in this

case when a beacon is received, since it results

in spurious values.

Subject: [PATCH] ath9k: Set ATH_OP_HW_RESET before HW reset
|
||||
|
||||
When a HW reset is done, the interrupt tasklet is
|
||||
disabled before ISRs are disabled in the HW. This
|
||||
allows a small window where the HW can still generate
|
||||
interrupts. Since the tasklet is disabled and not killed,
|
||||
it is not scheduled but deferred for execution at a later
|
||||
time.
|
||||
|
||||
This happens because ATH_OP_HW_RESET is not set when ath_reset()
|
||||
is called. When the hw_reset_work workqueue is used, this
|
||||
problem doesn't arise because ATH_OP_HW_RESET is set
|
||||
and the ISR bails out.
|
||||
|
||||
Set ATH_OP_HW_RESET properly in ath_reset() to avoid
|
||||
this race - all the ath_reset_internal() callers have
|
||||
been converted to use ath_reset() in the previous patch.
|

Subject: [PATCH] ath9k: Fix MCC flush timeout
|
||||
|
||||
In MCC mode, the duration for a channel context
|
||||
is half the beacon interval and having a large
|
||||
flush timeout will adversely affect GO operation,
|
||||
since the default value of 200ms will overshoot
|
||||
the advertised NoA absence duration.
|
||||
|
||||
The scheduler initiates a channel context switch
|
||||
only when the slot duration for the current
|
||||
context expires, so there is no possibility of
|
||||
having a fixed timeout for flush.
|
||||
|
||||
Since the channel_switch_time is added to the
|
||||
absence duration when the GO sets up the NoA
|
||||
attribute, this is the maximum time that we
|
||||
have to flush the TX queues. The duration is very
|
||||
small, but we don't have a choice in MCC mode.

Subject: [PATCH] ath9k: Check for pending frames properly
|
||||
|
||||
Pending frames in the driver can be present
|
||||
either in the HW queues or SW. ath9k_has_pending_frames()
|
||||
currently checks for the HW queues first and then
|
||||
checks if any ACs are queued in the driver.
|
||||
|
||||
In MCC mode, we need to check the HW queues alone, since
|
||||
the SW queues are just marked as 'stopped' - they will
|
||||
be processed in the next context switch. But since we
|
||||
don't differentiate this now, mention whether we want
|
||||
to check if there are frames in the SW queues.
|
||||
|
||||
* The flush() callback checks both HW and SW queues.
|
||||
* The tx_frames_pending() callback does the same.
|
||||
* The call to __ath9k_flush() in MCC mode checks HW queues alone.

Since both the arguments need to satisfy
|
||||
the alignment requirements of ether_addr_copy(),
|
||||
use memcpy() in cases where there will be no
|
||||
big performance benefit and make sure that
|
||||
ether_addr_copy() calls use properly aligned
|
||||
arguments.

Subject: [PATCH] ath9k: Fix RoC expiration
|
||||
|
||||
mac80211 has to be notified when a RoC period
|
||||
expires in the driver. In MCC mode, since the
|
||||
offchannel/RoC timer is set with the requested
|
||||
duration, ieee80211_remain_on_channel_expired() needs
|
||||
to be called when the timer expires.
|
||||
|
||||
But, currently it is done after we move back to
|
||||
the operating channel. This is incorrect - fix this
|
||||
by calling ieee80211_remain_on_channel_expired() when
|
||||
the RoC timer expires and in ath_roc_complete() when
|
||||
the RoC request is aborted.

Subject: [PATCH] ath9k: Improve flush() in mcc mode
|
||||
|
||||
The flush timeout in MCC mode is very small, since
|
||||
we are constrained by the time slice for each
|
||||
channel context, but since only the HW queues are
|
||||
flushed when switching contexts, it is acceptable.
|
||||
|
||||
Since the SW queues are also emptied in the mac80211 flush()
|
||||
callback, a larger duration is needed. Add an override
|
||||
argument to __ath9k_flush() and set it when flush()
|
||||
is called in MCC mode. This allows the driver to
|
||||
drain both the SW and HW queues.

Subject: [PATCH] ath9k: Do not start BA when scanning
|
||||
|
||||
mac80211 currently has a race which can be hit
|
||||
with this sequence:
|
||||
|
||||
* Start a scan operation.
|
||||
* TX BA is initiated by ieee80211_start_tx_ba_session().
|
||||
* Driver sets up internal state and calls
|
||||
ieee80211_start_tx_ba_cb_irqsafe().
|
||||
* mac80211 adds a packet to sdata->skb_queue with
|
||||
type IEEE80211_SDATA_QUEUE_AGG_START.
|
||||
* ieee80211_iface_work() doesn't process the
|
||||
packet because scan is in progress.
|
||||
* ADDBA response timer expires and the sta/tid is
|
||||
torn down.
|
||||
* Driver receives BA stop notification and calls
|
||||
ieee80211_stop_tx_ba_cb_irqsafe().
|
||||
* This is also added to the queue by mac80211.
|
||||
* Now, scan finishes.
|
||||
|
||||
At this point, the queued up packets might be processed
|
||||
if some other operation schedules the sdata work. Since
|
||||
the tids have been cleaned up already, warnings are hit.
|
||||
|
||||
If this doesn't happen, the packets are left in the queue
|
||||
until the interface is torn down.
|
||||
|
||||
Since initiating a BA session when scan is in progress
|
||||
leads to flaky connections, especially in MCC mode, we
|
||||
can drop the TX BA request. This improves connectivity
|
||||
with legacy clients in MCC mode.

Subject: [PATCH] ath9k: fix processing RXORN interrupts
|
||||
|
||||
The "goto chip_reset" is a bit misleading, because it does not actually
|
||||
issue a chip reset. Instead it is bypassing processing of other
|
||||
interrupts and assumes that the tasklet will issue a chip reset.
|
||||
|
||||
In the case of RXORN this does not happen, so bypassing processing of
|
||||
other interrupts will simply allow them to fire again. Even if RXORN
|
||||
was triggering a reset, it is not critical enough to need the bypass
|
||||
here.

When NF calibration fails, the radio often becomes deaf. The usual

hardware hang checks do not detect this, so it's better to issue a reset

when that happens.

Subject: [PATCH] ath9k: allow disabling bands via platform data
|
||||
|
||||
Some devices have multiple bands enables in the EEPROM data, even though
|
||||
they are only calibrated for one. Allow platform data to disable
|
||||
unsupported bands.
