rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.

rtw88: add BT co-existence support
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.

For RTL8822BE: rtw88/rtw8822b_fw.bin

And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.

rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.
Finally, rtw88 has many authors, listed alphabetically:

This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.

rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.

rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.
Finally, rtw88 has many authors, listed alphabetically:

rtw88: add phy_info debugfs to show Tx/Rx physical status
This commit adds several Tx/Rx physical information to phy_info
debugfs for 8822B/8822C. By this debugfs, we can know physical
information, such as Tx/Rx rate, RSSI, EVM,SNR, etc. The
information is gotten from the packets of Tx/Rx path. It has
no impact for the performance of 8822B/8822C.
In the fields, we may meet different kinds of problems, but
we may have no professional instrument to check them. At
this moment, this debugfs is a good tool, and it may provide
useful information for debug.

* TRX statictics misleading, as we are not reporting status correctly,

rtw88: add phy_info debugfs to show Tx/Rx physical status
This commit adds several Tx/Rx physical information to phy_info
debugfs for 8822B/8822C. By this debugfs, we can know physical
information, such as Tx/Rx rate, RSSI, EVM,SNR, etc. The
information is gotten from the packets of Tx/Rx path. It has
no impact for the performance of 8822B/8822C.
In the fields, we may meet different kinds of problems, but
we may have no professional instrument to check them. At
this moment, this debugfs is a good tool, and it may provide
useful information for debug.

rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.

rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.

rtw88: add BT co-existence support
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.

except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.
Finally, rtw88 has many authors, listed alphabetically:

rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.

rtw88: add BT co-existence support
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.

rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.
Finally, rtw88 has many authors, listed alphabetically:

rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.
Finally, rtw88 has many authors, listed alphabetically:

Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.

rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.

rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.
Finally, rtw88 has many authors, listed alphabetically:

rtw88: add BT co-existence support
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.

rtw88: add a debugfs entry to dump coex's info
Add a new entry "coex_info" in debugfs to dump coex's states for
us to debug on coex's issues.
The basic concept for co-existence (coex, usually for WiFi + BT)
is to decide a strategy based on the current status of WiFi and
BT. So, it means the WiFi driver requires to gather information
from BT side and choose a strategy (TDMA/table/HW settings).
Althrough we can easily check the current status of WiFi, e.g.,
from kernel log or just dump the hardware registers, it is still
very difficult for us to gather so many different types of WiFi
states (such as RFE config, antenna, channel/band, TRX, Power
save). Also we will need BT's information that is stored in
"struct rtw_coex". So it is necessary for us to have a debugfs
that can dump all of the WiFi/BT information required.
Note that to debug on coex related issues, we usually need a
longer period of time of coex_info dump every 2 seconds (for
example, 30 secs, so we should have 15 times of coex_info's
dump).

rtw88: new Realtek 802.11ac driver
This is a new mac80211 driver for Realtek 802.11ac wireless network chips.
rtw88 now supports RTL8822BE/RTL8822CE now, with basic station mode
functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.
Finally, rtw88 has many authors, listed alphabetically:

functionalities. The firmware for both can be found at linux-firmware.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
For RTL8822BE: rtw88/rtw8822b_fw.bin
For RTL8822CE: rtw88/rtw8822c_fw.bin
And for now, only PCI buses (RTL8xxxE) are supported. We will add support
for USB and SDIO in the future. The bus interface abstraction can be seen
in this driver such as hci.h. Most of the hardware setting are the same
except for some TRX path or probing setup should be separated.
Supported:
* Basic STA/AP/ADHOC mode, and TDLS (STA is well tested)
Missing feature:
* WOW/PNO
* USB & SDIO bus (such as RTL8xxxU/RTL8xxxS)
* BT coexistence (8822B/8822C are combo ICs)
* Multiple interfaces (for now single STA is better supported)
* Dynamic hardware calibrations (to improve/stabilize performance)
Potential problems:
* static calibration spends too much time, and it is painful for
driver to leave IDLE state. And slows down associate process.
But reload function are under development, will be added soon!
* TRX statictics misleading, as we are not reporting status correctly,
or say, not reporting for "every" packet.
The next patch set should have BT coexistence code since RTL8822B/C are
combo ICs, and the driver for BT can be found after Linux Kernel v4.20.
So it is better to add it first to make WiFi + BT work concurrently.
Although now rtw88 is simple but we are developing more features for it.
Even we want to add support for more chips such as RTL8821C/RTL8814B.

rtw88: add BT co-existence support
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.

rtw88: add a debugfs entry to dump coex's info
Add a new entry "coex_info" in debugfs to dump coex's states for
us to debug on coex's issues.
The basic concept for co-existence (coex, usually for WiFi + BT)
is to decide a strategy based on the current status of WiFi and
BT. So, it means the WiFi driver requires to gather information
from BT side and choose a strategy (TDMA/table/HW settings).
Althrough we can easily check the current status of WiFi, e.g.,
from kernel log or just dump the hardware registers, it is still
very difficult for us to gather so many different types of WiFi
states (such as RFE config, antenna, channel/band, TRX, Power
save). Also we will need BT's information that is stored in
"struct rtw_coex". So it is necessary for us to have a debugfs
that can dump all of the WiFi/BT information required.
Note that to debug on coex related issues, we usually need a
longer period of time of coex_info dump every 2 seconds (for
example, 30 secs, so we should have 15 times of coex_info's
dump).
