[PATCH 01/13] wifi: ath12k: Update enum wmi_direct_buffer_module

[Raj Kumar Bhagat]

From: Rajat Soni <quic_rajson@quicinc.com>

Currently firmware is sending module id as 2 that is not supported.
This causes functional failure in driver.
Firmware added support for WMI_CONFIG_MODULE_CV_UPLOAD.
Add enum WMI_CONFIG_MODULE_CV_UPLOAD in wmi_direct_buffer_module to
resolve this issue.

I think the above would be more clearly written as something like:
Currently firmware supports sending three different values for enum 
wmi_direct_buffer_module, but the host currently only supports 2; 
support for WMI_DIRECT_BUF_CV_UPLOAD is missing. This cause a functional 
failure on the host because... (what is the problem? the fact that host 
doesn't allocate buffers for CV upload? or does the value of 2 cause a 
buffer overread/write of an array sized with WMI_DIRECT_BUFFER_MAX

> Add enum WMI_CONFIG_MODULE_CV_UPLOAD in wmi_direct_buffer_module to

you actually added WMI_DIRECT_BUF_CV_UPLOAD

[PATCH 02/13] wifi: ath12k: indicate NON MBSSID vdev by default during vdev start

[Raj Kumar Bhagat]

From: Sriram R <quic_srirrama@quicinc.com>

When any VDEV is started, MBSSID flags are passed to firmware to
indicate if its a MBSSID/EMA AP vdev. If the interface is not an AP
or if the AP doesn't support MBSSID, the vdev needs to be brought up
as a non MBSSID vdev. Set these flags as a non MBSSID AP by default
which can be updated as and when MBSSID support is added in ath12k.

only the 1st one is used. do we need the rest at this point?
perhaps add the others as they are needed?

note that "vap" is a non-standard term that ideally should not be used 
in ath12k (although a few references are present)

> +};

these seem to be added at some random place in the file. considering 
that these are applicable to the mbssid_flags in struct 
wmi_vdev_start_request_cmd, I'd suggest:

1) defining the enum just before this struct
2) naming the enum, i.e. wmi_vdev_mbssid_flags
3) using a prefix that matches the name, i.e. 
WMI_VDEV_MBSSID_FLAGS_NON_MBSSID_AP
4) in struct wmi_vdev_start_request_cmd add a comment to:
	__le32 mbssid_flags; /* uses enum wmi_vdev_mbssid_flags */

[PATCH 03/13] wifi: ath12k: fetch correct pdev id from WMI_SERVICE_READY_EXT_EVENTID

[Raj Kumar Bhagat]

From: Sowmiya Sree Elavalagan <quic_ssreeela@quicinc.com>

Currently while fetching for pdev id from WMI_SERVICE_READY_EXT_EVENTID
we consider 32 bit pdev_id in ath12k_wmi_caps_ext_params structure. But
Firmware sends lower 16 bit for pdev id along with higher 16 bit for
hw_link_id. Due to this wrong pdev id is fetched. This wrong pdev id
when used for WMI commands leads to Firmware crash.

Hence fetch the correct pdev id considering only the lower 16 bits.

[PATCH 04/13] wifi: ath12k: add support for peer meta data version

[Raj Kumar Bhagat]

From: Harshitha Prem <quic_hprem@quicinc.com>

Add support to process WMI_TLV_SERVICE_PEER_METADATA_V1A_V1B_SUPPORT
service bit. If this service bit is set by firmware, then it expects
host to set rx_peer_meta_data_ver in wmi_resource_config's flags2
with value 3 for QCN9274 to indicate as V1B meta version. If this is
not set firmware crash is seen during peer addition.

Hence, if WMI_TLV_SERVICE_PEER_METADATA_V1A_V1B_SUPPORT service bit
is set by firmware, set correct peer metadata version to avoid
firmware crash.

[PATCH 05/13] wifi: ath12k: fix fetching MCBC flag for QCN9274

[Raj Kumar Bhagat]

In QCN9274, RX packet's multicast and broadcast(MCBC) flag is fetched
from RX descriptor's msdu_end info5 member but it is not correct
for QCN9274. Due to this with encryption, ARP request packet is wrongly
marked as MCBC packet and it is sent to mac80211 without setting
RX_FLAG_PN_VALIDATED & RX_FLAG_DECRYPTED flag. This results in packet
getting dropped in mac80211. Hence ping initiated from station to AP
fails.

Fix this by fetching correct MCBC flag in case of QCN9274.
For QC9274 MCBC flag should be fetched from RX descriptor's mpdu_start
info6 member.

[PATCH 06/13] wifi: ath12k: Add logic to write QRTR node id to scratch

[Raj Kumar Bhagat]

From: P Praneesh <quic_ppranees@quicinc.com>

Currently only one MHI device is registered successfully on platform
having two or more identical MHI devices. This is beacuse QMI service
runs with identical QRTR node ID. And, qrtr-lookup cannot register
more than one QMI service with identical node ID.

Hence, generate a unique QRTR instance ID from PCIe domain number and
bus number. QMI allows node id to be written on scratch register.
Add logic to write QRTR node id to the register. It is available for
firmware to uniquely identify an instance.

BTW we got a test report that this breaks WCN7850 support.

[PATCH 07/13] wifi: ath12k: fix firmware assert during insmod in memory segment mode

[Raj Kumar Bhagat]

From: Aaradhana Sahu <quic_aarasahu@quicinc.com>

In segment memory mode, firmware allocates memory segments of size
2 MB. This 2 MB memory is used by firmware for the number of peers.
This number of peer is sent from host to firmware during WMI init
command. For single-phy the number of peers sent is
TARGET_NUM_PEERS_SINGLE = 529 (512 + 17). While for split-phy number
of peers sent to firmware is TARGET_NUM_PEERS_DBS = 2 *(512 + 17) =
1058. With this 1058 number of peers firmware is unable to allocate
memory in 2 MB segment and firmware crash is observed.

Hence, fix this firmware crash by reducing the number of stations
TARGET_NUM_STATIONS for split-phy.

[PATCH 08/13] wifi: ath12k: split hal_ops to support RX TLVs word mask compaction

[Raj Kumar Bhagat]

With word mask subscription support, the rx_desc structure will
change. The fields in this structure rx_desc will be reduced to only
the required fields. To make word mask subscription changes compatible
with the older firmware version (firmware that does not support word
mask subscription), two different structures of rx_desc will be
required for the same hardware.

Most of the hal_ops are directly related to rx_desc.

Hence, split hal_ops into operations that are independent of rx_desc
(hal_ops) and the operations that are directly dependent on rx_desc
(hal_rx_ops). These hal_rx_ops depend on both hardware and firmware
hence move them out of hw_params.

[PATCH 09/13] wifi: ath12k: remove hal_desc_sz from hw params

[Raj Kumar Bhagat]

With word mask subscription support, the rx_desc structure will
change. The fields in this structure rx_desc will be reduced to only
the required fields. To make word mask subscription changes compatible
with the older firmware version (firmware that does not support word
mask subscription), two different structures of rx_desc will be
required for the same hardware.

The hardware param hal_desc_sz value cannot be constant for the same
hardware. It depends on the size of rx_desc structure which may
change based on firmware capability to support word mask subscription.
Hence, remove hal_desc_sz from hardware param and add hal_rx_ops
to get the size of rx_desc in run time.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00188-QCAHKSWPL_SILICONZ-1
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1

[PATCH 10/13] wifi: ath12k: subscribe required word mask from rx tlv

[Raj Kumar Bhagat]

From: Karthikeyan Kathirvel <quic_kathirve@quicinc.com>

Most of the RX descriptors fields are currently not used in the
ath12k driver. Hence add support to selectively subscribe to the
required quad words (64 bits) within msdu_end and mpdu_start of
rx_desc.

Add compact rx_desc structures and configure the bit mask for Rx TLVs
(msdu_end, mpdu_start, mpdu_end) via registers. With these registers
SW can configure to DMA the partial TLV struct to Rx buffer.

Each TLV type has its own register to configure the mask value.
The mask value configured in register will indicate if a particular
QWORD has to be written to rx buffer or not i.e., if Nth bit is enabled
in the mask Nth QWORD will be written and it will not be written if the
bit is disabled in mask. While 0th bit indicates whether TLV tag will be
written or not.

Advantages of Qword subscription of TLVs
- Avoid multiple cache-line misses as the all the required fields
of the TLV are within 128 bytes.
- Memory optimization as TLVs + DATA + SHINFO can fit in 2k buffer
even for 64 bit kernel.

I only have one comment on this patch.

in order to avoid chipset-specific logic here suggest that there should 
be an abstraction.

several ideas come to mind:
1) have a hal_ops callback to retrieve it
2) have a pointer to the compact ops in the hw_params

since we are already using hal_ops to get the masks, suggest that is 
where we should get the pointer to the compact ops

Thanks Jeff for the suggestion, will implement hal_ops to retrieve
the corresponding compact ops.

[PATCH 11/13] wifi: ath12k: add MAC id support in WBM error path

[Raj Kumar Bhagat]

From: Karthikeyan Periyasamy <quic_periyasa@quicinc.com>

When more than one pdev is supported in the chip/SoC, the packet
belonging to second pdev is given to first pdev due to not identifying
the MAC id in the WBM error path. So ping fails.

In WBM error path, src link id information not available in the
descriptor. So get this information from the msdu_end 64bit tag. It
is necessary to get the src link id to identify the MAC id in the
given chip. Then only we can pass the skb to the corresponding pdev.

based upon the code it seems this only works when compact descriptors 
are in use? IMO that should be highlighted.

[PATCH 12/13] wifi: ath12k: fix PCI read and write

[Raj Kumar Bhagat]

From: P Praneesh <quic_ppranees@quicinc.com>

Currently, PCI read is failing for the registers belonging to
SECURITY_CONTROL_WLAN registers. These registers read is required
to read the board-id to identify the dual-mac QCN9274 hardware.

The failure is because, for these registers (SECURITY_CONTROL_WLAN)
offset, ath12k_pci_get_window_start() returns window_start as 0. Due
to this PCI read is done without PCI select window and with
window_start offset as 0.

Hence, fix PCI read and write by doing PCI select window and by using
the correct window_start offset - WINDOW_START for
SECURITY_CONTROL_WLAN registers.

[PATCH 13/13] wifi: ath12k: Read board id to support split-PHY QCN9274

[Raj Kumar Bhagat]

From: Ganesh Babu Jothiram <quic_gjothira@quicinc.com>

QCN9274 can support single-PHY or split-PHY architecture. Currently,
only the single-PHY architecture is supported in ath12k.

The split-PHY QCN9274 requires different AMSS firmware binary
"amss_dualmac.bin".

Hence, add support to read board id from OTP. Based on board id
decide whether single-mac / dual-mac firmware needs to be downloaded
to the target. Also, update HW param max_radios to support split-PHY
in QCN9274.
