Emmanuel Grumbach f98ad635c0 iwlwifi: pcie: don't access periphery registers when not available
The periphery can't be accessed before we set the
INIT_DONE bit which initializes the device.

A previous patch added a reconfiguration of the MSI-X
tables upon resume, but at that point in the flow,
INIT_DONE wasn't set. Since the reconfiguration of the
MSI-X tables require periphery access, it failed.

The difference between WoWLAN and without WoWLAN is that
in WoWLAN, iwl_trans_pcie_d3_suspend clears the INIT_DONE
without clearing the STATUS_DEVICE_ENABLED bit in the
software status. Because of that, the resume code thinks
that the device is enabled, but the INIT_DONE bit has been
cleared.

To fix this, don't reconfigure the MSI-X tables in case
WoWLAN is enabled. It will be done in
iwl_trans_pcie_d3_resume anyway.

bd, the free list, uses the iwl_rx_transfer_desc,
in which the vid is stored in the structs' rbid
field, and the page address in the addr field.

used_bd, the used list, uses the iwl_rx_completion_desc
struct, in which the vid is stored in the structs' rbid
field.

rb_stts, the hw "write" pointer of rx is stored in a
__le16 array, in which each entry represents the write
pointer per queue.

The tx power applied by set_txpower is limited by the CTL (conformance

Depending on the EEPROM data this can cause the tx power to become too
limited, if the original regdomain CTLs impose lower limits than the CTLs
of the user configured regdomain.

restrictions and only apply the CTL at run time when setting the channel

Sven Eckelmann 3f25911158 ath10k: prevent active scans on potential unusable channels
The QCA4019 hw1.0 firmware 10.4-3.2.1-00050 and 10.4-3.5.3-00053 (and most
likely all other) seem to ignore the WMI_CHAN_FLAG_DFS flag during the
scan. This results in transmission (probe requests) on channels which are
not "available" for transmissions.

Since the firmware is closed source and nothing can be done from our side
to fix the problem in it, the driver has to work around this problem. The
WMI_CHAN_FLAG_PASSIVE seems to be interpreted by the firmware to not
scan actively on a channel unless an AP was detected on it. Simple probe
requests will then be transmitted by the STA on the channel.

ath10k must therefore also use this flag when it queues a radar channel for
scanning. This should reduce the chance of an active scan when the channel
might be "unusable" for transmissions.

Rafał Miłecki 1e591c56a6 brcmfmac: specify some features per firmware version
Some features supported by firmware aren't advertised and there is no
way for a driver to query them. This includes e.g. monitor mode details.

Most firmwares support monitor interface but only the latest ones
/announce/ it with a "monitor" flag in the "cap" iovar. There isn't any
reliable detection method for older firmwares (BRCMF_C_MONITOR was tried
but "it only indicates the core part of the stack supports").

Similarly support for tagging monitor frames and building radiotap
headers can't be reliably detected for all firmwares.

This commit adds table that allows mapping features to firmware version.
It adds mappings for 43602a1 and 4366b1 firmwares from
linux-firmware.git. Both were confirmed to be passing monitor frames.

Maharaja Kennadyrajan db251d7df4 ath10k: add debugfs file warm_hw_reset
Debugfs support to do hardware warm reset with WMI command
WMI_PDEV_PARAM_PDEV_RESET for 10.4 and 10.2.4(if wmi
service is enabled in the firmware for backward compatibility).

This change is purely for debugging purpose when hardware hangs/mutes.

This hardware reset won't affect the connectivity but there will be small
pause in data traffic. Here we are doing BB/MAC level reset and hence
whenever the BB/MAC watchdog is triggered, it does a hardware_chip_reset.
So the target will be in the active state.

Below command used to warm reset the hardware.

The tx completion of multiple mgmt frames can be bundled
in a single event and sent by the firmware to host, if this
capability is not disabled explicitly by the host. If the host
cannot handle the bundled mgmt tx completion, this capability
support needs to be disabled in the wmi init cmd, sent to the firmware.

Add the host capability indication flag in the wmi ready command,
to let firmware know the features supported by the host driver.
This field is ignored if it is not supported by firmware.

Set the host capability indication flag(i.e. host_capab) to zero,
for disabling the support of bundle mgmt tx completion. This will
indicate the firmware to send completion event for every mgmt tx
completion, instead of bundling them together and sending in a single
event.

Golan Ben Ami 1a4968d123 iwlwifi: pcie: support 2k rx buffers
The smallest rb size supported today is 4k rx buffers.
22560 devices use 2k rxb's, so allow using 2k buffers.

Golan Ben Ami d0158235f4 iwlwifi: update registers changed for 22560 devices
In 22560 devices the firmware will do all the hw configurations,
but that's not ready yet.
Update the correct registers in the driver until the FW is ready
and does it by itself.

Golan Ben Ami cf495496b6 iwlwifi: introduce new rx structures used by 22560 RFH
22560 devices RFH uses different structures, which act similar
to the legacy rxq management lists - free and used list.

The iwl_rx_transfer_desc struct is part of the free list,
and consists of pointers to the empty rb's the driver wants to
pass to the fw.

The iwl_rx_completion_desc struct is part of the used list,
and consists of pointers to the buffer the fw filled up
with new rx, both commands and data, for the host.

Golan Ben Ami f5955a6cc3 iwlwifi: cancel the injective function between hw pointers to tfd entry index
Nowadays, the tfd queue max size is 2^8, and the reserved size in the
command header sequence field for the tfd entry index is 8 bits,
allowing an injective function from the hw pointers to the tfd entry index
in the sequence field.

In 22560 devices the tfd queue max size is 2^16, meaning that
the hw pointers are 16 bit long (allowing to point to each entry
in the tfd queue). However, the reserved space in the sequence field for
the tfd entry doesn't change, and we are limited to 8 bit.
This requires cancelling the injective function from hw pointer to
tfd entry in the sequence number.

Use iwl_pcie_get_cmd_index to wrap the hw pointer's to the n_window
size, which is maximum 256 in tx queues, and so, keep the injective
function between the window wrapped hw pointers to tfd entry index in
the sequence.

In 22560 devices the ROM sendis an interrupt to the host

Handle this interrupt, and indicate sw error in case the

Additionally, the cause for sw error in 22560 devices
have been changed, so update the cause list.
