Re: [PATCH v3 00/49] ath11k: driver for Qualcomm IEEE 802.11ax devices

Kalle Valo [off-list ref] writes:

ath11k is a new driver for Qualcomm IEEE 802.11ax devices, first
supporting only IPQ8074 SoC using the shared memory AHB bus. ath11k
uses mac80211 and supports AP, Station and Mesh modes.

Even though ath11k has some similar code as with ath10k (especially
the WMI layer) it was concluded to be simpler to have a "clean start"
for ath11k code base and not try to share the code with ath10k. This
makes maintenance easier and avoids major changes in ath10k, which
would have significantly increased the risk of regressions in existing
setups.

Even though the driver is very similar with ath10k but there are major
differences as well. The datapath is completely different. ath11k
supports multiple MACs, called "soc" in the firmware interface. And
there's only one WMI interface to support.

Currently ath11k supports only IEEE 802.11ac mode, but patches for
802.11ax are available and they will be submitted after ath11k is
accepted to upstream.

The firmware images are available from ath11k-firmware repository but
they will be also submitted to linux-firmware:

https://github.com/kvalo/ath11k-firmware

I also added to the commit log the version which was used in testing:

WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1

--------------[cut]-------------------[cut]-----------------

I have split the driver into multiple patches for easier review, but
the final version will be split into three commits:

1. adding Documentatio/devicetree/bindings/net/wireless/qcom,ath11k.yaml

2. adding drivers/net/wireless/ath/ath11k/ with the commit log being the
   text before the cut line above.

3. adding ath11k entry to MAINTAINERS file

This version is based on commit ad10d2ff619f0797cb102b2ff488429d3f8e4a8a
from ath11k-bringup branch on my ath.git tree:

https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/log/?h=ath11k-bringup

This patchset applies to wireless-drivers-next but needs
CONFIG_COMPILE_TEST, CONFIG_REMOTEPROC AND CONFIG_QCOM_QMI_HELPERS to
be able to compile on x86.

Please review and comment.

I have now prepared the three commits and they are in the pending
branch for build testing:

https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=pending&id=20bddf19da715842fe24c8e9990ae1b75825c747

https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=pending&id=461a5c86cfa562bd3c4a8f6bec9a54c406540e87

https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=pending&id=8710785df81b8b57e62a71e9048c111a7db98005

In the next few days I'll apply these to ath-next branch and queue for v5.6.
