Subject: [PATCH] wifi: rtw88: add missing call to cancel_work_sync()
|
||||
|
||||
Lukas reports skb_over_panic errors on his Banana Pi BPI-CM4 which comes
|
||||
with an Amlogic A311D (G12B) SoC and a RTL8822CS SDIO wifi/Bluetooth
|
||||
combo card. The error he observed is identical to what has been fixed
|
||||
in commit e967229ead0e ("wifi: rtw88: sdio: Check the HISR RX_REQUEST
|
||||
bit in rtw_sdio_rx_isr()") but that commit didn't fix Lukas' problem.
|
||||
Add missing call to 'cancel_work_sync()' in 'rtw_core_stop()'.
|
||||
|
||||
Lukas found that disabling or limiting RX aggregation works around the
|
||||
problem for some time (but does not fully fix it). In the following
|
||||
discussion a few key topics have been discussed which have an impact on
|
||||
this problem:
|
||||
- The Amlogic A311D (G12B) SoC has a hardware bug in the SDIO controller
|
||||
which prevents DMA transfers. Instead all transfers need to go through
|
||||
the controller SRAM which limits transfers to 1536 bytes
|
||||
- rtw88 chips don't split incoming (RX) packets, so if a big packet is
|
||||
received this is forwarded to the host in it's original form
|
||||
- rtw88 chips can do RX aggregation, meaning more multiple incoming
|
||||
packets can be pulled by the host from the card with one MMC/SDIO
|
||||
transfer. This Depends on settings in the REG_RXDMA_AGG_PG_TH
|
||||
register (BIT_RXDMA_AGG_PG_TH limits the number of packets that will
|
||||
be aggregated, BIT_DMA_AGG_TO_V1 configures a timeout for aggregation
|
||||
and BIT_EN_PRE_CALC makes the chip honor the limits more effectively)
|
||||
|
||||
Use multiple consecutive reads in rtw_sdio_read_port() and limit the
|
||||
number of bytes which are copied by the host from the card in one
|
||||
MMC/SDIO transfer. This allows receiving a buffer that's larger than
|
||||
the hosts max_req_size (number of bytes which can be transferred in
|
||||
one MMC/SDIO transfer). As a result of this the skb_over_panic error
|
||||
is gone as the rtw88 driver is now able to receive more than 1536 bytes
|
||||
from the card (either because the incoming packet is larger than that
|
||||
or because multiple packets have been aggregated).
|
||||
|
||||
In case of an receive errors (-EILSEQ has been observed by Lukas) we
|
||||
need to drain the remaining data from the card's buffer, otherwise the
|
||||
card will return corrupt data for the next rtw_sdio_read_port() call.

Changes since v2 at [2]:
|
||||
- Don't initialize err to zero as that intiial value is never used.
|
||||
Thanks Ping-Ke for spotting this!
|
||||
- Add a comment explaning why we need to continue reading but still
|
||||
have to return an error to the caller of rtw_sdio_read_port()
|
||||
|
||||
Changes since v1 at [0]:
|
||||
- We need to read all bytes if we split the transaction into multiple
|
||||
smaller reads. This is even the case when one of N reads reports an
|
||||
error. Otherwise the next read port call will return garbage (partially
|
||||
containing zeros, ...). A similar-ish approach can be found in the
|
||||
vendor driver, see [1] (specifically the call to sdio_recv_and_drop())
|
||||
- Update the patch description accordingly
|
||||
|
||||
With a preliminary version of this updated patch Lukas reported off-
|
||||

|

|
||||
This is caused by a mistake in the chip initialisation. This version of
|
||||
the chip requires loading an extra AGC table right after the main one,
|
||||
but the extra table is being loaded at the wrong time, in
|
||||
rtw_chip_board_info_setup().
|
||||
|
||||
Move the extra AGC table loading to the right place, in
|
||||
rtw_phy_load_tables().
|
||||
|
||||
The rtw_chip_board_info_setup() can only do "software" things, and
|
||||
rtw_phy_load_tables() can really do IO.

|
||||
|
||||
From: Nick Morrow <morrownr@gmail.com>
|
||||
|
||||
Purpose: Add VID/PIDs that are known to be missing for this driver.
|
||||
- removed /* 8811CU */ and /* 8821CU */ as they are redundant
|
||||
since the file is specific to those chips.
|
||||
- removed /* TOTOLINK A650UA v3 */ as the manufacturer. It has a REALTEK
|
||||
VID so it may not be specific to this adapter.

||||

||||

Subject: [PATCH v2 1/4] wifi: rtw88: 8821cu: Fix firmware upload fail
|
||||
|
||||
Lukas reports skb_over_panic errors on his Banana Pi BPI-CM4 which comes
|
||||
with an Amlogic A311D (G12B) SoC and a RTL8822CS SDIO wifi/Bluetooth
|
||||
combo card. The error he observed is identical to what has been fixed
|
||||
in commit e967229ead0e ("wifi: rtw88: sdio: Check the HISR RX_REQUEST
|
||||
bit in rtw_sdio_rx_isr()") but that commit didn't fix Lukas' problem.
|
||||
RTL8822CU, RTL8822BU, and RTL8821CU need an extra register write after
|
||||
reading and writing certain addresses.
|
||||
|
||||
Lukas found that disabling or limiting RX aggregation works around the
|
||||
problem for some time (but does not fully fix it). In the following
|
||||
discussion a few key topics have been discussed which have an impact on
|
||||
this problem:
|
||||
- The Amlogic A311D (G12B) SoC has a hardware bug in the SDIO controller
|
||||
which prevents DMA transfers. Instead all transfers need to go through
|
||||
the controller SRAM which limits transfers to 1536 bytes
|
||||
- rtw88 chips don't split incoming (RX) packets, so if a big packet is
|
||||
received this is forwarded to the host in it's original form
|
||||
- rtw88 chips can do RX aggregation, meaning more multiple incoming
|
||||
packets can be pulled by the host from the card with one MMC/SDIO
|
||||
transfer. This Depends on settings in the REG_RXDMA_AGG_PG_TH
|
||||
register (BIT_RXDMA_AGG_PG_TH limits the number of packets that will
|
||||
be aggregated, BIT_DMA_AGG_TO_V1 configures a timeout for aggregation
|
||||
and BIT_EN_PRE_CALC makes the chip honor the limits more effectively)
|
||||
Without this, the firmware upload fails approximately more than 50% of
|
||||
the time.
|
||||
|
||||
Use multiple consecutive reads in rtw_sdio_read_port() and limit the
|
||||
number of bytes which are copied by the host from the card in one
|
||||
MMC/SDIO transfer. This allows receiving a buffer that's larger than
|
||||
the hosts max_req_size (number of bytes which can be transferred in
|
||||
one MMC/SDIO transfer). As a result of this the skb_over_panic error
|
||||
is gone as the rtw88 driver is now able to receive more than 1536 bytes
|
||||
from the card (either because the incoming packet is larger than that
|
||||
or because multiple packets have been aggregated).
|
||||
Tested with RTL8811CU (Tenda U9 V2.0) which is the same as RTL8821CU
|
||||
but without Bluetooth.
|
||||
|
||||
In case of an receive errors (-EILSEQ has been observed by Lukas) we
|
||||
need to drain the remaining data from the card's buffer, otherwise the
|
||||
card will return corrupt data for the next rtw_sdio_read_port() call.

Changes since v2 at [2]:
|
||||
- Don't initialize err to zero as that intiial value is never used.
|
||||
Thanks Ping-Ke for spotting this!
|
||||
- Add a comment explaning why we need to continue reading but still
|
||||
have to return an error to the caller of rtw_sdio_read_port()
|
||||
|
||||
Changes since v1 at [0]:
|
||||
- We need to read all bytes if we split the transaction into multiple
|
||||
smaller reads. This is even the case when one of N reads reports an
|
||||
error. Otherwise the next read port call will return garbage (partially
|
||||
containing zeros, ...). A similar-ish approach can be found in the
|
||||
vendor driver, see [1] (specifically the call to sdio_recv_and_drop())
|
||||
- Update the patch description accordingly
|
||||
|
||||
With a preliminary version of this updated patch Lukas reported off-
|
||||
list: "i've been using this laptop for almost 3 hours with heavy wifi
|
||||
usage and so far no problems"

This is caused by a mistake in the chip initialisation. This version of
|
||||
the chip requires loading an extra AGC table right after the main one,
|
||||
but the extra table is being loaded at the wrong time, in
|
||||
rtw_chip_board_info_setup().
|
||||
|
||||
Move the extra AGC table loading to the right place, in
|
||||
rtw_phy_load_tables().
|
||||
|
||||
The rtw_chip_board_info_setup() can only do "software" things, and
|
||||
rtw_phy_load_tables() can really do IO.

Subject: [PATCHi V2] wifi: rtw88: Add missing VID/PIDs doe 8811CU and 8821CU
|
||||
|
||||
From: Nick Morrow <morrownr@gmail.com>
|
||||
|
||||
Purpose: Add VID/PIDs that are known to be missing for this driver.
|
||||
- removed /* 8811CU */ and /* 8821CU */ as they are redundant
|
||||
since the file is specific to those chips.
|
||||
- removed /* TOTOLINK A650UA v3 */ as the manufacturer. It has a REALTEK
|
||||
VID so it may not be specific to this adapter.
|
||||

||||

Subject: [PATCH v2 1/4] wifi: rtw88: 8821cu: Fix firmware upload fail
|
||||
|
||||
RTL8822CU, RTL8822BU, and RTL8821CU need an extra register write after
|
||||
reading and writing certain addresses.
|
||||
|
||||
Without this, the firmware upload fails approximately more than 50% of
|
||||
the time.
|
||||
|
||||
Tested with RTL8811CU (Tenda U9 V2.0) which is the same as RTL8821CU
|
||||
but without Bluetooth.

|

This is caused by a mistake in the chip initialisation. This version of
|
||||
the chip requires loading an extra AGC table right after the main one,
|
||||
but the extra table is being loaded at the wrong time, in
|
||||
rtw_chip_board_info_setup().
|
||||
|
||||
Move the extra AGC table loading to the right place, in
|
||||
rtw_phy_load_tables().
|
||||
|
||||
The rtw_chip_board_info_setup() can only do "software" things, and
|
||||
rtw_phy_load_tables() can really do IO.

From: Bitterblue Smith <rtl8821cerfe2@gmail.com>
|

Subject: [PATCHi V2] wifi: rtw88: Add missing VID/PIDs doe 8811CU and 8821CU
|
||||
|
||||
From: Nick Morrow <morrownr@gmail.com>
|
||||
|
||||
Purpose: Add VID/PIDs that are known to be missing for this driver.
|
||||
- removed /* 8811CU */ and /* 8821CU */ as they are redundant
|
||||
since the file is specific to those chips.
|
||||
- removed /* TOTOLINK A650UA v3 */ as the manufacturer. It has a REALTEK
|
||||
VID so it may not be specific to this adapter.
|
||||
|
||||
