According to many bugreports [0][1][2] the default ath10k-ct kernel
module is unusable on devices with just 64 MiB RAM or with 128 MiB and
dual ath10k cards. The target boards boot but eventually oom-killer
starts to interfere with normal operation, so the current state is
effectively broken.
Since the two patches in question have a performance impact (and
possibly some other unexpected side-effects) a dedicated build variant
is added so that users of the low RAM devices can still benefit from all
the ath10k-ct advantages.
According to testing [3] results, the issue can be experienced even with
"a 256MB device with three radios". Measured performance impact of
implementing small buffers was lowering "the maximum 5 GHz throughput on
an IPQ40xx device without RPS/XPS optimizations from 494/432 Mbit/s for
TCP transfers (download/upload) to 438/343 Mbit/s"
The patches were apparently inspired by QSDK tweaks used by ODMs for the
affected devices.

OpenWrt currently only uses the version 4.19, but we still ship some

Most of the txpower for the ath10k firmware is stored as twicepower (0.5 dB
steps). This isn't the case for max_antenna_gain - which is still expected
by the firmware as dB.
The firmware is converting it from dB to the internal (twicepower)
representation when it calculates the limits of a channel. This can be seen
in tpc_stats when configuring "12" as max_antenna_gain. Instead of the
expected 12 (6 dB), the tpc_stats shows 24 (12 dB).

If no mcast_rate is set for the wifi-iface then there is no rate_idx (0)
set for the bss. This can break for example 5GHz meshpoint interfaces
because 0 maps to a CCK rate (11Mbit/s).
It must also be avoided that the ath10k-ct internal state for the rates is
not synced with the mac80211 rates state. Otherwise, the user specified
rate (e.g. a wifi-iface mcast_rate for a meshpoint interface) will only be
set on startup. And a short while after that, ath10k-ct specific code in
ath10k_check_apply_special_rates is missing a valid rate in its own
structures and is then recalculating a new default rate. This default rate
is in most situations not the requested rate.

By default the firmware uses 1Mbps and 6Mbps rate for management packets
in 2G and 5G bands respectively. But when the user selects different
basic rates from the userspace, we need to send the management
packets at the lowest basic rate selected by the user.
This change makes use of WMI_VDEV_PARAM_MGMT_RATE param for configuring the
management packets rate to the firmware.

Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified on QCA4019 using bus, bmi-chip-id and
bmi-board-id.
The problem, however, can occur when the (default) board data file cannot
fulfill the vendor requirements and it is necessary to use a different
board data file.
This problem was solved for SMBIOS by adding a special SMBIOS type 0xF8.
Something similar has to be provided for systems without SMBIOS but with
device trees. No solution was specified by QCA and therefore a new one has
to be found for ath10k.
The device tree requires addition strings to define the variant name
wifi@a000000 {
status = "okay";
qcom,ath10k-calibration-variant = "RT-AC58U";
};
wifi@a800000 {
status = "okay";
qcom,ath10k-calibration-variant = "RT-AC58U";
};
This would create the boarddata identifiers for the board-2.bin search
* bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=RT-AC58U
* bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=RT-AC58U

The missing dependency causes build problems on systems without PCI
support.
The ath10k_pci kernel module depends on PCI support so this dependency
should be added. ath10k now also supported the ahb interface on the
IPQ4019 SoC, but this SoC also has PCI support so this extra dependency
is not as problem.
