Subject: [PATCH 0/5] rtw88: add support for BT co-existence mechanism

From: Yan-Hsuan Chuang <[email protected]>

This patch set mainly adds a BT co-existence mechanism, which
helps WiFi device to work with BT device concurrently without
interfering each other. For Realtek's WiFi/BT combo devices,
the co-existence mechanism is on the WiFi side.

The first two patches "rtw88: switch specified efuse bank" and
"rtw88: check efuse for BT FT S1" aim to check if the device
is able to run with WiFi + BT, because some of the earlier
devices manufactured are in development for testing. These
device hence did not program the efuse for BT. Without being
programed, some of the hardware parameters are incorrect.

The rest of the patches add BTcoex support. BTcoex needs to
wake up events that is waiting for some C2H reported in IRQ
context, so these C2H skbs do not required to be queued into
workqueues to be processed. What we need to do is to simply
wake it uin IRQ context.

And actually C2H workqueue context should be protected by
rtwdev->mutex lock to perform some hardware operations
against mac80211 callbacks.

The final patch contains the most of the BTcoex logic.
It is not that complicated, just to gather information and
make decision on WiFi driver side. What makes the code so
much is that the mechanism needs to take care of a lot of
WiFi/BT combinations. Such as if WiFi is at 2G or is having
a lot of traffic or is connecting to AP. And BT has many
profiles such as A2DP/HID/PAN or it is slave or not.




Yan-Hsuan Chuang (5):
rtw88: switch specified efuse bank
rtw88: check efuse for BT FT S1
rtw88: allow c2h operation in irq context
rtw88: enclose c2h cmd handle with mutex
rtw88: add BT co-existence support

Subject: [PATCH 5/5] rtw88: add BT co-existence support

From: Yan-Hsuan Chuang <[email protected]>

Both RTL8822BE/RTL8822CE are WiFi + BT combo chips. Since
WiFi and BT use 2.4GHz to transmit, it is important to
make sure they run concurrently without interfering each
other. To achieve this, WiFi driver requires a mechanism
to collaborate with BT, whether they share the antenna(s)
or not.

The final decision made by the co-existence mechanism is
to choose a proper strategy, or called "tdma/table", and
inform either firmware or hardware of the strategy.
To choose a strategy, co-existence mechanism needs to
have enough information from WiFi and BT.

BT information is provided through firmware C2H.
The contents describe the current status of BT, such as
if BT is connected or is idle, or the profile that is
being used.

WiFi information can be provided by WiFi itself. The WiFi
driver will call various of "notify" functions each time
the state of WiFi changed, such as WiFi is going to switch
channel or is connected. Also WiFi driver can know if it
shares antenna with BT by reading efuse content. Antenna
configuration of the module will finally get a different
strategy.

Upon receiving any information from WiFi or BT, the WiFi
driver will run the co-existence mechanism immediately.
It will set the RF antenna configuration according to the
strategy through the TDMA H2C to firmware and a hardware
table. Based on the tdma/table, WiFi + BT should work with
each other, and having a better user experience.

Subject: [PATCH 4/5] rtw88: enclose c2h cmd handle with mutex

From: Yan-Hsuan Chuang <[email protected]>

C2H commands that cannot be handled in IRQ context should
be protected by rtwdev->mutex. Because they might have a
sequece of hardware operations that does not want to be
interfered.
