From: Luca Coelho <[email protected]>
Hi,
Here's the first set of patches intended for v5.13. It's the usual
development, new features, cleanups and bugfixes.
The changes are:
* Add support for new FTM FW APIs;
* Some CSA fixes;
* Support for new HW family and other HW detection fixes;
* Robustness improvement in the HW detection code;
* Some other small fixes, clean-ups and improvements.
As usual, I'm pushing this to a pending branch, for kbuild bot, and
will send a pull-request later.
Please review.
Cheers,
Luca.

2.31.0
From: Mordechay Goodstein <[email protected]>
For simplicity we assume that msix has 2 IRQ lines one used for rx data
called msix_non_share, and another used for one bit flags messages
(alive, hw error, sw error, rx data flag) called msix_share.
Every time the FW has data to send it puts it on the RX queue and HW
turns on the flags in msix_share (inta_fw) indicating about rx data,
and HW sends an interrupt a bit later to the msix_non_share _unless_
the msix_shared RX data bit was cleared.
Currently in the code every time we get an msix_shared we clear all bits
including rx data queue bits.
So we can have a race
----------------------------------------------------
DRIVER | HW | FW
----------------------------------------------------
- send host cmd to FW | |
| | - handle message
| | and put a response
| | on the RX queue
| - RX flag on |
| | - send alive msix
| - alive flag on |
| - interrupt |
| msix_share driver |
- handle msix_shared | |
and clear all flags | |
bits | |
| - don't send an |
| interrupt on |
| msix_non_shared |
| (driver cleared) |
- driver timeout on | |
waiting for host cmd | |
respond | |
| |
----------------------------------------------------
The change is to clear only the msi_shared flags that are handled in
the msix_shared flow, which will cause the hardware to send an interrupt
on the msix_non_share line as well, when it has data.

Add support for different combinations of Bz
and CRFs.
Note: As of now we do not know the exact values
for ltr_delay and xtal_latency, so for now use the
worst case scenario values until the actual values
are clarified.

2.31.0
From: Johannes Berg <[email protected]>
If we (for example) have a trans_cfg entry in the PCI IDs table,
but then don't find a full cfg entry for it in the info table,
we fall through to the code that treats the PCI ID table entry
as a full cfg entry. This obviously causes crashes later, e.g.
when trying to build the firmware name string.
Avoid such crashes by using the low bit of the pointer as a tag
for trans_cfg entries (automatically using a macro that checks
the type when assigning) and then checking that before trying to
use the data as a full entry - if it's just a partial entry at
that point, fail.
Since we're adding some macro magic, also check that the type is
in fact either struct iwl_cfg_trans_params or struct iwl_cfg,
failing compilation ("initializer element is not constant") if
it isn't.

From: Sara Sharon <[email protected]>
When moving to the new channel, we block TX until we hear the
first beacon. if it is not heard, we proceed to disconnect.
Since TX is blocked (without mac80211 being aware of it) the frame
is stuck, resulting with queue hang.
Instead, reenable TX before reporting on the connection loss.
As we are on the new channel, there is no problem with that,
even if the original CSA had quiet mode.
