driver will call multiple tx wake notify to wake firmware
within a short time. In this situation, firmware may miss
power mode change request from driver and leads to status

three times to make sure firmware could get the request.

In current flow, FW is asynchronously loaded after alloc_hw(). It defers
the decision on FW feature map. It makes things difficult for us to decide
whether to hook chanctx ops, which should be decided while alloc_hw() is
calling. Still, asynchronous gets its advantages. So, we want to resolve
this without dropping them.
Based on multi-FW flag, RTW89_MFW_SIG, we can determine runtime FW is
multi-FW (MFW) or single FW (SFW). Both of them have a quite small chunk
for header at the head. The difference is that MFW doesn't describe version
code in its header while SFW does. So, we plan to extend MFW header for
version code. After that, in both cases, we can determine FW feature map by
just FW header. And, according to the map, we can decide chanctx.
So, we call request_partial_firmware_into_buf() to request a quite small
chunk before alloc_hw() to get a early FW feature map without affecting
things much and only use early map to decide whether to hook chanctx ops.
It means that if non-extended MFW is used at runtime, driver just acts
without chanctx as before. If extended MFW or SFW, which supports required
FW features, is used at runtime, driver can hook chanctx ops to mac80211 if
chip has configured support_chanctx_num > 0.
Besides, key point for now to support single one chanctx is whether HW scan
is supported at runtime. So, we configure all chip's support_chanctx_num to
1, and check if HW scan is supported at runtime via early FW feature map.

Some HW features are required if we hook chanctx ops to mac80211. With it,
mac80211 would expect the HW-supported variant ops exists on some behavior,
e.g. HW scan. But, HW features may depend on chip's FW or its development.
Besides, how many chanctx can be supported also depends on chip design.
We can neither decide whether to generally support chanctx ops nor how many
chanctx can be supported.
So, support_chanctx_num is added under chip info to deal with this by chip.
For now, all chip configure support_chanctx_num as 0. We haven't really
hook chanctx ops yet. So, chip can run without mac80211 chanctx as before.

For now, we support single one channel and use only first HW entry,

unexpected, the entity mode should always be RTW89_ENT_MODE_SCC after

While idle, we need a default chandef to set channel for things,
such as scan. Before support of mac80211 chanctx, mac80211 would
configure a default one on ieee80211_hw::conf::chandef. And we
just queried it whenever we did set channel. However, after support
of mac80211 chanctx, the flow won't work like before.
Besides, we don't now query chandef from ieee80211_hw::conf::chandef
either. So, similar to mac80211 without using chanctx, we configure
the default chandef with ieee80211_channel of index 0 in 2GHz.
Although we have not added the support of mac80211 chanctx here,
this configuration should be compatible before that. So, we commit

above assumption would be broken. So, we adjust a bit ahead to reduce

After this, we don't query ieee80211_hw::conf::chandef directly, and

Sometimes we need to write current rtw89_chan outside set_channel(),
e.g. during HW scan, we adjust it to align FW process through C2H.
However, we don't have full parameters to fill entire rtw89_chan.
And it will breakage if we update only part of current rtw89_chan.
That is what we don't want to see because most flows throughout
driver treat rtw89_chan as a whole.
So, we divide struct rtw89_chan to basic part and derived part. The
basic part contains the parameters which we are always able to know.
And the derived part will be calculated by the basic part. Then, a
central function, rtw89_chan_create(), is added to deal with this.

We will implement and support chanctx with single channel first, i.e.
only use entry in RTW89_SUB_ENTITY_0, before handling dual channels.
Our hierarchy in planning will become as the following.

---> entity (manage status across sub-entities)

We need to invoke the callback of the changed band at the first
set_channel() after every power-off. Originally, we forced the
channel to be 0 when doing power-off, and then determined things
by comparing channel with 0.
However, deciding on such things by channel might be confusing.
It's also confusing to use this kind of decision when we consider
multiple channels in the follow-up patches. So, another flag,
entity_active, is added ahead to HAL to deal with this.
Besides, we also need to check if entity is active when we set
TX power.

To improve VO throughput, we enable VO TX AMPDU.
We measure the latency of enable or disable VO TX AMPDU. The experimental
results show that the difference between the two is insignificant only
300µs, so the little impact can be ignored for user experience.
Moreover, we found some APs will have a group key handshake timeout issue
when the EAPOL's TID is already setup BA session. Therefore, when
transmitting EAPOL, if EAPOL's TID BA session is already setup, we need
to delete it.

The BSSID mask of H2C is used to match BSSID of receiving packets.
Normally, we set six bits BSSID mask to exactly match BSSID of packets
sent by target AP. After we support multiple BSSID, it could connect a
nontransmitted BSSID, so we can only match first five bytes of BSSID.
That means we could possibly receive other AP's packets if only the last
byte of BSSID is different from target AP.

Since SAR is more expected to follow U-NII bands to plan subbands,
division of 6GHz band is quite different from defined enum of subbands
which is used by PHY in most cases. It's hard and painful if we want to
keep using the same enum on SAR. So, we introduce another enum for SAR
subbands and adjust SAR flow to use it.
Besides, since 6GHz SAR subbands won't be divided with edge alignment,
some cases will span two SAR subbands. For these cases, we describe them
within an array of rtw89_sar_span and take the smaller one between SAR
settings of the two subbands.

The design of INT indicator register (R_AX_PCIE_HIMR00_V1) is to reduce IO
during frequent interrupts, because it can stop chip sending interrupt to
host if we just set this indicator to 0, not all IMR(s). This indicator
register looks like a root interrupt controller of wifi chip.
However, we can't set all other IMR(s) to 0 during we are running on
interrupt service routine, or the indicator register can't reflect the
status of certain interrupt happened during this period, and then miss
some interrupts especially SER interrupt events.

Currently in mac80211 each STA object is represented
using sta_info datastructure with the associated
STA specific information and drivers access ieee80211_sta
part of it.
With MLO (Multi Link Operation) support being added
in 802.11be standard, though the association is logically
with a single Multi Link capable STA, at the physical level
communication can happen via different advertised
links (uniquely identified by Channel, operating class,
BSSID) and hence the need to handle multiple link
STA parameters within a composite sta_info object
called the MLD STA. The different link STA part of
MLD STA are identified using the link address which can
be same or different as the MLD STA address and unique
link id based on the link vif.
To support extension of such a model, the sta_info
datastructure is modified to hold multiple link STA
objects with link specific params currently within
sta_info moved to this new structure. Similarly this is
done for ieee80211_sta as well which will be accessed
within mac80211 as well as by drivers, hence trivial
driver changes are expected to support this.
For current non MLO supported drivers, only one link STA
is present and link information is accessed via 'deflink'
member.
For MLO drivers, we still need to define the APIs etc. to
get the correct link ID and access the correct part of
the station info.
Currently in mac80211, all link STA info are accessed directly
via deflink. These will be updated to access via link pointers
indexed by link id with MLO support patches, with link id
being 0 for non MLO supported cases.
Except for couple of macro related changes, below spatch takes
care of updating mac80211 and driver code to access to the
link STA info via deflink.

Originally, there is already a mechanism, SER (system error recover),
to deal with HW/FW recovery. After FW v0.13.36.0, FW supports a H2C
(host to chip) command to make a CPU exception. Then, SER is supposed
to catch this FW crash and do L2 reset. This feature is a simulation
to verify if flow of recovering from FW crash works.
Usage of fw_crash debugfs is as the following.
$ echo 1 > fw_crash // trigger FW crash and wait SER handling
$ cat fw_crash // return 0 if restart has been done

It contains a list of RA (return address) and SP (stack pointer) which

When FW encounters exception or assertion, SER L2 reset process will start.
It will dump some error information and re-download FW eventually. Since
such errors are usually critical, we would like to keep more information
about error to increase possibility of analysis and debugging FW. We first
add FW payload engine (fw reserved playoad engine, fw_rsvd_ple) memory
dump. FW will record things like CPU registers, backtrace entry, etc. in it
for debugging.
Moreover, device core dump framework is used and wrapped to collect kinds

The CAM, meaning address CAM and bssid CAM here, will get leaks during
SER (system error recover) L2 reset process and ieee80211_restart_hw()
which is called by L2 reset process eventually.
The normal flow would be like
-> add interface (acquire 1)
-> enter ips (release 1)
-> leave ips (acquire 1)
-> connection (occupy 1) <(A) 1 leak after L2 reset if non-sec connection>
The ieee80211_restart_hw() flow (under connection)
-> ieee80211 reconfig
-> add interface (acquire 1)
-> leave ips (acquire 1)
-> connection (occupy (A) + 2) <(B) 1 more leak>
Originally, CAM is released before HW restart only if connection is under
security. Now, release CAM whatever connection it is to fix leak in (A).
OTOH, check if CAM is already valid to avoid acquiring multiple times to
fix (B).
Besides, if AP mode, release address CAM of all stations before HW restart.

Firmware sends out beacon content generated by mac80211, and then stations
can receive beacon and work with this AP properly. Also, we download
beacon content again if TIM is changed.

BA CAM is used to ACK peer's packets, so it must be established when
IEEE80211_AMPDU_RX_START, and free it by IEEE80211_AMPDU_RX_STOP.
The hardware can support two static BA CAM entries, so I implement a bitmap
and a struct to record which entry is used and its corresponding tid. Also,
the hardware can learn and create dynamic BA CAM entries automatically if
received packets don't match static BA CAM. That means it can still work if
we don't use H2C to set static BA CAM. An exception is tid=0 should be
always allocated in static BA CAM, so an existing static BA CAM will be
replaced if it is full and peer is going to establish a BA with tid=0.
The new firmware use new format of this H2C, so I upgrade it as well.

We are planning to support more chipsets, e.g. 8852C. Before that, we
consider architecutre to handle multiple kinds of chipsets. Obviosuly,
based on original design, rtw89_core module will have large size even
if there is only one chipset under running. It is because all chipset
related things are put in rtw89_core now. To reduce such overhead, we
extract modules of rtw89 and adjust dependencies between modules.
The following assumes that 8852AE, 8852AU, and 8852CE are all supported,
we describe the difference before and after extraction.
[Before extraction]
-------------
|------------------------------------ | rtw89_usb |
V -------------
--------------------------------------- -------------
| rtw89_core (including 8852A, 8852C) | <--- | rtw89_pci |
--------------------------------------- -------------
The data of 8852A and 8852C are built in rtw89_core.
And rtw89_pci is the entry of 8852AE and 8852CE.
And rtw89_usb is the entry of 8852AU.
[After extraction]
------------- ----------------
|----------- | rtw89_usb | <-------- | rtw89_8852au |
| ------------- ----------------
V --------------- |
-------------- | | <---------------
| rtw89_core | <--- | rtw89_8852a |
-------------- | | <---------------
^ ^ --------------- |
| | ------------- ----------------
| | | | <-------- | rtw89_8852ae |
| |----------- | rtw89_pci | ----------------
| | | <-----------------
| ------------- |
| --------------- ----------------
|--------------- | rtw89_8852c | <------ | rtw89_8852ce |
--------------- ----------------
The data of 8852A/8852C is extracted to rtw89_8852a/rtw89_8852c.
And rtw89_pci/rtw89_usb handles only common flow of pci/usb bus.
Finally, 8852AE, 8852AU, and 8852CE have individual entry modules,
i.e. rtw89_8852ae, rtw89_8852au, and rtw89_8852ce correspondingly.

Since sock.h is modified relatively often (60 times in the last
12 months) it seems worthwhile to decrease the incremental build
work.
CoDel's header includes net/inet_ecn.h which in turn includes net/sock.h.
codel.h is itself included by mac80211 which is included by much of
the WiFi stack and drivers. Removing the net/inet_ecn.h include from
CoDel breaks the dependecy between WiFi and sock.h.
Commit d068ca2ae2 ("codel: split into multiple files") moved all
the code which actually needs ECN helpers out to net/codel_impl.h,
the include can be moved there as well.
This decreases the incremental build size after touching sock.h
from 4999 objects to 4051 objects.
Fix unmasked missing includes in WiFi drivers.

cch_by_bw as parameters to query other configurations. However,

It's easier to use and understand, and to extend for EHT later,
if we use the values here instead of the shifted values.
Unfortunately, we need to add _POS so that we can use it in
places like iwlwifi/mvm where constants are needed.
While at it, fix the typo ("NOMIMAL") which also helps catch any
conflicts.

The RF register array is used to help firmware to restore RF settings.
The original code can potentially access out of range, if the size is
between (RTW89_H2C_RF_PAGE_SIZE * RTW89_H2C_RF_PAGE_NUM + 1) to
((RTW89_H2C_RF_PAGE_SIZE + 1) * RTW89_H2C_RF_PAGE_NUM). Fortunately,
current used size doesn't fall into the wrong case, and the size will not
change if we don't update RF parameter.

The partition size is used to tell hardware the size of piece we are going
to send a firmware. The old code updates the size in constant buffer of
firmware, and leads system crash.
To fix this, update the size on skb->data after we copy the firmware data
into skb.

This driver named rtw89, which is the next generation of rtw88, supports
Realtek 8852AE 802.11ax 2x2 chip whose new features are OFDMA, DBCC,
Spatial reuse, TWT and BSS coloring; now some of them aren't implemented
though.
The chip architecture is entirely different from the chips supported by
rtw88 like RTL8822CE 802.11ac chip. First of all, register address ranges
are totally redefined, so it's impossible to reuse register definition. To
communicate with firmware, new H2C/C2H format is proposed. In order to have
better utilization, TX DMA flow is changed to two stages DMA. To provide
rich RX status information, additional RX PPDU packets are added.
Since there are so many differences mentioned above, we decide to propose
a new driver. It has many authors, they are listed in alphabetic order:
