From: Avri Altman <avri.altman@intel.com>
Today, the driver logic looks for the conditions to disable
power management albeit power management should be enabled
in a very few distinct cases.
This patch changes the driver logic to enable power
management once the required conditions met.
While at it, make some housekeeping and support a few
additional use cases:
a) Add support for a standalone p2p client:
Power management should be enabled for a P2P client
MAC only if the firmware supports it (TLV flag is set).
Instead we used the DCM flag, therefore we didn't cover
use cases that did not include the DCM flag.
b) Add support to Same-Channel-Mode (SCM):
If both clients share the same channel (SCM), and there
are no other active vifs in the system, power management
should be enabled only if the firmware supports this
(TLV flag is set).
c) Fix power management logic for GO/AP:
Today, when we detect an active GO / AP MAC - we disable
power management for all the vifs altogether.
Actually, the correct behavior is to enable power
management on a client if on a different channel
(based on the firmware capabilities).
d) Housekeeping - Along with that, this patch includes some
code-reorganizing: Today the logic of disabling power is
scattered across several functions, specifically in the
iterator. For the sake of both readability and
scalability, we moved this logic to its applicable
function, leaving the iterator gather information only.
Furthermore, as power management is a MAC-related
attribute, we moved the power management member to the
iwl_mvm_vif structure.

A hardware bug had been discovered on 7260 / 3160 and 7265
and the workaround for this bug is to force the NIC to stay
awake as long as we have host commands in flight. This
workaround has been introduced for all NICs in a previous
patch:
b9439491055a ("iwlwifi: pcie: keep the NIC awake when commands are in flight")
In newer NICs, this bug is solved, so we can let the NIC go
to sleep even when we send commands. The hardware will wake
up when we increment the scheduler write pointer.
Make the workaround conditional to only use it on affected
hardware.

The fw recently added an option to set tx power reduction
per station (in the lq_cmd command), and get the tx power
reduction used (in the tx_resp struct).
Use them and propogate this value up to mac80211's tx
response (in order to use it later in the rate-scaling
algorithm).

Implement Adaptive Tx Power Control algorithm.
ATPC basically tries to decrease the tx power
as much as possible while the throughput is
not being hurt.

Allow fixing the tx power reduction through debugfs
file.
The change doesn't take affect immediately, but
will be considered the next time tpc is evaluated.

To: linux-wireless; +Cc: Johannes Berg, Emmanuel Grumbach
From: Johannes Berg <johannes.berg@intel.com>
Use the new NAPI infrastructure added to mac80211 to get
GRO. We don't really implement NAPI since we don't have
a real poll function and we never schedule a NAPI poll.
Instead of this, we collect all the packets we got from a
single interrupt and then call napi_gro_flush().
This allows us to benefit from GRO. In half duplex medium
like WiFi, its main advantage is that it reduces the number
of TCP Acks, hence improving the TCP Rx performance.
Since we call the Rx path with a spinlock held, remove
the might_sleep mention from the op_mode's API.

From: Johannes Berg <johannes.berg@intel.com>
When shadow registers are enabled, then need_update never needs
to be set, so move the need_update handling into the function
that really needs to do it (iwl_pcie_rxq_inc_wr_ptr) and also
separate the check when it woke up. While at it, convert it to
bool.
This also clarifies the locking and means the irq_lock needs to
no longer be held for any such updates.
The irq_lock also doesn't have to be held for restocking since
everything else locks the RX queue properly, so remove that and
finally disentangle the two locks entirely so there aren't any
dependencies between the two left.

Instead of using u8 to hold logic values, use bool.
Also fix a comment, the return value is no longer relevant.

When updating the write pointer, the TX queue should be locked
to get consistent state, fix that in the interrupt handler.

Similar to the recent RX queue patch, this changes the need_update
handling for the TX queues to be clearer and only done when needed.

Besides the different allocation flags, they are really
the same. Pass the gfp_t flags as a parameter, and unify
them.

The firmware tells us if an Rx packet was beamformed or not.
Propagate this data to mac80211's rx_status.vht_flags.
The main user of this data is the radiotap header.

Now that mac80211 calls pre_rcu_remove and we set the
fw_id_to_mac_id pointer to -ENOENT before the station is
removed, we don't need to set fw_id_to_mac_id to -EINVAL
when the station is really removed.
Leave fw_id_to_mac_id to be -ENOENT which will let the
drain worker (iwl_mvm_sta_drained_wk) know that this station
is not to be drained.
We don't need to drain this station since it is our AP in
managed mode and we flush all its frames synchronously
anyway.
Setting the AP station to -EINVAL could lead to confusion
since internal stations are also reserved with -EINVAL,
this confusion showed up in the logs as:
Drained sta 0, but it is internal?

The Rx FIFO includes valuable data - dump it when the FW
asserts. Also - free the SRAM and Rx FIFO when we create
the file, and don't collect new SRAM / Rx FIFO if the
previous file hasn't been collected through debugfs yet.
Also - add a comment to saying that the ASSERT output should
not be modified since we have automatic scripts that monitor
this output.

When NIC is exiting from thermal throttling state (i.e. after
heating and then cooling down), tx-backoff values are assigned
to be zero, instead of being restored to the minimal value. Fixed.

rcu_assign_pointer() ensures that the initialization of a structure is
carried out before storing a pointer to that structure. However, in the
case that NULL is assigned there's no structure to initialize so using
RCU_INIT_POINTER instead is safe and more efficient.

While the scan_cmd should really be allocated in init (and
we do fail init in case the allocation failed), it doesn't
mean we should lock up the machine if something really bad
happened.

This firmware is not supported any more.
A few code paths specific to old firmware can be removed.
We can now assume that a few TLV flags are always set since
we won't load firmware that didn't support the corresponding
features. This will be done in a separate patch.

Do not allow passive scan fragmentation in case of P2P discovery
scan. This is to avoid negative impact on P2P discoverability.
Do some re-factoring to make existing code more clear.

The BT Coex API underwent a minor backward compatible API

Calling iwl_send_bt_init_conf for INIT firmware is not a
problem, and calling iwl_send_bt_prio_tbl from
iwl_send_bt_init_conf allows us to prepare for new API.

To: linux-wireless; +Cc: Haim Dreyfuss, Alexander Bondar, Emmanuel Grumbach
From: Haim Dreyfuss <haim.dreyfuss@intel.com>
This patch enables Energy Based Scan (EBS) - intended to detect energy
on 5 GHz band channels. Passive scan on this band takes up to 2.64 sec
assuming 110mSec per-channel * 24 channels. EBS is designed to detect
energy on channels with intensive Wifi activity as well as those where
only beacons are transmitted. EBS completes sampling all channels within
shortest beacon frame transmission time. Total EBS duration is about 100
msec (typical beacon interval).
Detecting Wifi activity on 5 GHz band channels can significantly reduce
scan duration thus saving time and power. EBS failure reported by FW
disables EBS for current connection. It is re-enabled upon new
connection attempt on any WLAN interface.

bail out from the suspend/resume callbacks if
d0i3 is used.
declare support for ANY wowlan trigger (i.e.
normal operation).
On resume, we shouldn't execute the d0i3 exit
flow (which might disconnect stations, etc.)
until mac80211 was resumed.
Add new flags to indicate we are in suspend,
and call the pending exit work on resume.
Since the resume flow can take some time, add
a new EXIT_WORK reference type to prevent going
back to d0i3 at this stage.

Somehow I added spaces instead of tabs to a few lines in
debugfs.c.

The driver can enable uAPSD and specify some of its related parameters.
This patch organizes this logic in a separate function.

7000 device series have a fix for this hardware feature.
Stop disabling it, and get an improvement in Tx throughput.
This feature allows the scheduler to fetch more frames on
the fly while an A-MPDU is being built - which means that
we can get larger A-MPDU. This, of course, give an
improvement in the Tx throughput.

Eliad has a brand new feature: we reduce the Tx power when the link allows - this reduces our power consumption. The regular changes in power and scan area. One interesting thing though is the patches from Johannes, we have now GRO which allows to increase our throughput in TCP Rx. The main advantage is that it reduces the number of TCP Acks - these TCP Acks are completely useless when we are using A-MPDU since the first packet of the A-MPDU generates a TCP Ack which is made obsolete by the next packets.
