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 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: associate reserved pages with each vif
Each device has only one reserved page shared with all of the
vifs, so it seems not reasonable to pass vif as one of the
arguments to rtw_fw_download_rsvd_page(). If driver is going
to run more than one vif, the content of reserved page could
not be built for all of the vifs.
To fix it, let each vif maintain its own reserved page list,
and build the final reserved page to download to the firmware
from all of the vifs. Hence driver should add reserved pages
to each vif according to the vif->type when adding the vif.
For station mode, add reserved page with rtw_add_rsvd_page_sta().
If the station mode is going to suspend in PNO (net-detect)
mode, remove the reserved pages used for normal mode, and add
new one for wowlan mode with rtw_add_rsvd_page_pno().
For beacon mode, only beacon is required to be added using
rtw_add_rsvd_page_bcn().
This would make the code flow simpler as we don't need to
add reserved pages when vif is running, just add/remove them
when ieee80211_ops::[add|remove]_interface.
When driver is going to download the reserved page, it will
collect pages from all of the vifs, this list is maintained
by rtwdev, with build_list as the pages' member. That way, we
can still build a list of reserved pages to be downloaded.
Also we can get the location of the pages from the list that
is maintained by rtwdev.
The biggest problem is that the first page should always be
beacon, if other type of reserved page is put in the first
page, the tx descriptor and offset could be wrong.
But station mode vif does not add beacon into its list, so
we need to add a dummy page in front of the list, to make
sure other pages will not be put in the first page. As the
dummy page is allocated when building the list, we must free
it before building a new list of reserved pages to firmware.

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: associate reserved pages with each vif
Each device has only one reserved page shared with all of the
vifs, so it seems not reasonable to pass vif as one of the
arguments to rtw_fw_download_rsvd_page(). If driver is going
to run more than one vif, the content of reserved page could
not be built for all of the vifs.
To fix it, let each vif maintain its own reserved page list,
and build the final reserved page to download to the firmware
from all of the vifs. Hence driver should add reserved pages
to each vif according to the vif->type when adding the vif.
For station mode, add reserved page with rtw_add_rsvd_page_sta().
If the station mode is going to suspend in PNO (net-detect)
mode, remove the reserved pages used for normal mode, and add
new one for wowlan mode with rtw_add_rsvd_page_pno().
For beacon mode, only beacon is required to be added using
rtw_add_rsvd_page_bcn().
This would make the code flow simpler as we don't need to
add reserved pages when vif is running, just add/remove them
when ieee80211_ops::[add|remove]_interface.
When driver is going to download the reserved page, it will
collect pages from all of the vifs, this list is maintained
by rtwdev, with build_list as the pages' member. That way, we
can still build a list of reserved pages to be downloaded.
Also we can get the location of the pages from the list that
is maintained by rtwdev.
The biggest problem is that the first page should always be
beacon, if other type of reserved page is put in the first
page, the tx descriptor and offset could be wrong.
But station mode vif does not add beacon into its list, so
we need to add a dummy page in front of the list, to make
sure other pages will not be put in the first page. As the
dummy page is allocated when building the list, we must free
it before building a new list of reserved pages to firmware.

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:

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: 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: 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.

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.

rtw88: associate reserved pages with each vif
Each device has only one reserved page shared with all of the
vifs, so it seems not reasonable to pass vif as one of the
arguments to rtw_fw_download_rsvd_page(). If driver is going
to run more than one vif, the content of reserved page could
not be built for all of the vifs.
To fix it, let each vif maintain its own reserved page list,
and build the final reserved page to download to the firmware
from all of the vifs. Hence driver should add reserved pages
to each vif according to the vif->type when adding the vif.
For station mode, add reserved page with rtw_add_rsvd_page_sta().
If the station mode is going to suspend in PNO (net-detect)
mode, remove the reserved pages used for normal mode, and add
new one for wowlan mode with rtw_add_rsvd_page_pno().
For beacon mode, only beacon is required to be added using
rtw_add_rsvd_page_bcn().
This would make the code flow simpler as we don't need to
add reserved pages when vif is running, just add/remove them
when ieee80211_ops::[add|remove]_interface.
When driver is going to download the reserved page, it will
collect pages from all of the vifs, this list is maintained
by rtwdev, with build_list as the pages' member. That way, we
can still build a list of reserved pages to be downloaded.
Also we can get the location of the pages from the list that
is maintained by rtwdev.
The biggest problem is that the first page should always be
beacon, if other type of reserved page is put in the first
page, the tx descriptor and offset could be wrong.
But station mode vif does not add beacon into its list, so
we need to add a dummy page in front of the list, to make
sure other pages will not be put in the first page. As the
dummy page is allocated when building the list, we must free
it before building a new list of reserved pages to firmware.
