ath12k is a new mac80211 driver for Qualcomm Wi-Fi 7 devices, first
supporting QCN9274 and WCN7850 PCI devices. QCN9274 supports both AP
and station; WCN7850 supports only station mode. Monitor mode is not
(yet) supported. Only PCI bus devices are supported.
ath12k is forked from an earlier version of ath11k. It was simpler to
have a "clean start" for the new generation and not try to share the
code with ath11k. This makes maintenance easier and avoids major
changes in ath11k, which would have significantly increased the risk
of regressions in existing setups.
ath12k uses le32 and cpu_to_le32() macros to handle endian
conversions, instead of using the firmware byte swap feature utilized
by ath11k. There is only one kernel module, named ath12k.ko.
Currently ath12k only supports HE mode (IEEE 802.11ax) or older, but
work is ongoing to add EHT mode (IEEE 802.11be) support.
The size of the driver is ~41 kLOC and 45 files. To make the review
easier, this initial version of ath12k does not support Device Tree,
debugfs or any other extra features. Those will be added later, after
ath12k is accepted to upstream.
The driver is build tested by Intel's kernel test robot with both GCC
and Clang. Sparse reports no warnings. The driver is mostly free of
checkpatch warnings, albeit few of the warnings are omitted on
purpose, list of them here:
https://github.com/qca/qca-swiss-army-knife/blob/master/tools/scripts/ath12k/ath12k-check#L52
The driver has had multiple authors who are listed in alphabetical
order below.

--------------[cut]-------------------[cut]-----------------
I have split the driver into multiple patches for easier review, but
the final version will be one big commit.
For easier review I have split the driver into multiple patches (one
file per patch). But in the final version, which will be commited to
git, all these patches will be folded into one big patch. So in the
git archive the full driver be in a single commit to avoid any bisect
issues etc.
This version is based on commit 313fb8aacbba1eae831065d7cb5c68cb97fcace6
from ath12k-bringup branch on my ath.git tree:
https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/log/?h=ath12k-bringup
The patchset applies on top of wireless-next commit:
bafe9528b792f4a442aa1ea2b0297cd53a0351ab
The firmware images are not yet available but they will be soon, the
plan is to publish them before v2 is submitted.
Please review and comment.

+ * This field is used to select one of the 'WHO_CLASSIFY_INFO's in the

+ * 0: To choose Flow 0 and 1 of any TID use this value.
+ * 1: To choose Flow 2 and 3 of any TID use this value.
+ * 2: To choose Flow 4 and 5 of any TID use this value.
+ * 3: To choose Flow 6 and 7 of any TID use this value.
+ *
+ * If who_classify_info sel is not in sync with the num_tx_classify_info
+ * field from address search, then TCL will set 'who_classify_info_sel'
+ * to 0 use flows 0 and 1.
+ *
+ * hlos_tid
+ * HLOS MSDU priority
+ * Field is used when HLOS_TID_overwrite is set.
+ *
+ * flow_override
+ * Field only valid when flow_override_enable is set to FP_USE_OVERRIDE
+ * TCL uses this to select the flow pointer from the peer table,
+ * which can be overridden by SW for pre-encrypted raw WiFi packets
+ * that cannot be parsed for UDP or for other MLO
+ * 0 - FP_USE_NON_UDP: Use the non-UDP flow pointer (flow 0)
+ * 1 - FP_USE_UDP: Use the UDP flow pointer (flow 1)
+ *
+ * pmac_id
+ * TCL uses this PMAC_ID in address search, i.e, while
+ * finding matching entry for the packet in AST corresponding
+ * to given PMAC_ID
+ *
+ * If PMAC ID is all 1s (=> value 3), it indicates wildcard
+ * match for any PMAC
+ *
+ * vdev_id
+ * Virtual device ID to check against the address search entry to
+ * avoid security issues from transmitting packets from an incorrect
+ * virtual device
+ *
+ * search_index
+ * The index that will be used for index based address or
+ * flow search. The field is valid when 'search_type' is 1 or 2.
+ *
+ * cache_set_num
+ *
+ * Cache set number that should be used to cache the index
+ * based search results, for address and flow search. This
+ * value should be equal to LSB four bits of the hash value of
+ * match data, in case of search index points to an entry which
+ * may be used in content based search also. The value can be
+ * anything when the entry pointed by search index will not be
+ * used for content based search.
+ *
+ * index_loop_override
+ * When set, address search and packet routing is forced to use
+ * 'search_index' instead of following the register configuration
+ * seleced by Bank_id.
+ *
+ * ring_id
+ * The buffer pointer ring ID.
+ * 0 refers to the IDLE ring
+ * 1 - N refers to other rings
+ *
+ * looping_count
+ *
+ * A count value that indicates the number of times the
+ * producer of entries into the Ring has looped around the
+ * ring.
+ *
+ * At initialization time, this value is set to 0. On the
+ * first loop, this value is set to 1. After the max value is
+ * reached allowed by the number of bits for this field, the
+ * count value continues with 0 again.
+ *
+ * In case SW is the consumer of the ring entries, it can

+ * check where the head pointer' of the ring is located once

+ * entries have been put into this ring...
+ *
+ * Also note that SW if it wants only needs to look at the

Usage of __packed seems incorrect since this is not an ABI buffer, and
packing will potentially result in some members being unaligned (ath11k
has struct ath11k_skb_cb packed as well).
Suggest removing __packed and using pahole to find the ideal layout
since the only concern is that this does not exceed

Should they be '__le32' instead of 'u32'?
This struct is used to fill data of ath12k_htc_send(), and the fields of
htc header are __le32:
struct ath12k_htc_hdr {
__le32 htc_info;
__le32 ctrl_info;
} __packed __aligned(4);
If above is correct, some struct(s) related to ath12k_htc_send() have similar problems:
struct htt_ver_req_cmd
struct htt_ppdu_stats_cfg_cmd
struct htt_rx_ring_selection_cfg_cmd
struct htt_ext_stats_cfg_cmd
struct htt_tx_ring_selection_cfg_cmd (miss __packed)

there are several references to ar->ab in this function.
suggest being consistent with ath12k_dbring_bufs_replenish() and define:
struct ath12k_base *ab = ar->ab;
and then s/ar->ab/ab/ in those accesses
this suggestion applies to other functions below since there are
multiple functions which have multiple ar->ab dereferences

s/ar->ab/ab/ in both of the above since you already have ab = ar->ab

why does this failure simply return whereas just previously upon the
failure of ath12k_dp_rx_peer_tid_setup() we goto peer_clean. don't we
need to do the peer_clean logic here as well to undo the
ath12k_dp_rx_peer_tid_setup() calls?

rather than be a void function with a writable param, why not return the

I would expect an enum initializer to be one of the enumerators.
0 is HAL_ENCRYPT_TYPE_WEP_40 -- is that really the correct value?

this initializer would be unnecessary if
ath12k_dp_tx_get_vdev_bank_config() returns the config as the function
return value instead of doing so by reference via a function param

i'm used to seeing deinit code do things in reverse order of init code,
but the above is doing things in the same order. yes it probably doesn't
matter in this case, but if you consistently deinit in reverse order of
init then you'll get it right in the cases where it does matter

not a fan of a bool named flag.
better would be a name that tells us what it means when the flag is set.
I see this issue throughout the dp_mon functions:
ath12k_dp_mon_process_ring(...bool flag)
ath12k_dp_mon_srng_process(...bool flag, ...)
looking further I see:
#define ATH12K_DP_TX_MONITOR_MODE 0
#define ATH12K_DP_RX_MONITOR_MODE 1
(note 0 and 1 are not bool enumerators)
and logic like:
if (flag == ATH12K_DP_RX_MONITOR_MODE) {
so IMO based upon this kind of logic it would make more sense to have
either:
an enum ath12k_dp_monitor_mode and use that everywhere, or
rename bool flag to bool rx_mode and use that everywhere

this is invariant so it should be assigned outside the loops. yes, the
compiler will probably do that for you, but why not do it yourself?

this block of code has the same issues as the RX block. in fact it seems
that this block is identical to the block above other than the flag and
the tx_mon_desc vs rx_mon_desc, so I'm curious if it could be refactored
into a single function that could be used by both tx and rx instead of
duplicating code

should the function return type be enum rate_info_bw to better describe it?

unnecessary assignment -- already set from ath12k_mac_vdev_start()

this violates the convention that info* is used for fields that are
accessed while rsvd* is used for fields that are not accessed. in
addition, use of magic number offsets is also not nice.
imo what would improve this code is to have accessor macros/inline
functions defined co-resident with the struct so that all the magic
numbers and magic fields are contained within the acessors, and the
actual code here looks really readable.

should there be an ieee80211.h function for this? we already have:

i'm very confused by this loop.
1) 'reaped' is only initialized at the begining of the function.
2) inside the loop the first time we call ath12k_dp_mon_process_ring()
'reaped' will be the # of packets reaped in that first iteration.
3) if this is < DP_MON_SERVICE_BUDGET then we will exit the function.
4) if this is >= DP_MON_SERVICE_BUDGET then we will loop again. in all
of the subsequent iterations 'reaped' will be increased by the number of
packets reaped (which could be 0!!!), and that ongoing sum will always
be >= DP_MON_SERVICE_BUDGET (at least until we wrap the counter!!) and
hence even if we don't reap any packets in the subsequent calls we will
continue to loop until we exceed the timeout.
So it seems that 'reaped' should be initialized to 0 inside the do loop.
In addition it seems strange to have a budget but then not defer
additional processing, i.e. yield(), if you use up the budget.

hw_cc is a very cryptic name. is there a better name for this?
presumably this has something to do with hardware giving us unique

I've only reviewed up to this point, but want to checkpoint my review

perhaps set hal->srng_config = NULL so that there isn't a dangling pointer?

shouldn't this be initialized to a enum nl80211_he_ru_alloc enumerator?
(0 is NL80211_RATE_INFO_HE_RU_ALLOC_26)

the timer_setup() seems like strange logic to have in a function named
ath12k_dp_rx_pdev_srng_alloc() -- that doesn't have anything to do with
srng allocation
perhaps that should be in a separate properly-named function?

is this really a safe iteration if you unlock & lock in the middle?
what prevents the tmp node from being deleted during this window?

should you log the peer_addr?
also it is preferable to unlock first, and then log

is the user_stats[] array maintained in a manner where the
"is_valid_peer_id" records are always at the beginning of the array?
if not, then don't you have an issue if entry 0 has is_valid_peer_id =
false and entry 1 has is_valid_peer_id = true and peer_id is matching
since in that case you'd return 0 instead of 1?

I am really confused about the above function.
The first two declarations have both data and hdr point to the skb->data.
So one would assume these are related structures. But instead we have:
struct ath_pktlog_hdr {
u16 flags;
u16 missed_cnt;
u16 log_type;
u16 size;
u32 timestamp;
u32 type_specific_data;
struct mlo_timestamp m_timestamp;
u8 payload[];
};
struct htt_pktlog_msg {
u32 hdr;
u8 payload[0];
};
this means the pdev_id = u32_get_bits() logic is somehow extracting the
pdev_id from the fields that hold the flags+missed_cnt
and the logic to write hdr->m_timestamp is somewhere in the middle of
the htt_pktlog_msg payload[].
now the only thing that I can guess is that the htt_pktlog_msg payload[]
begins with:
u16 log_type;
u16 size;
u32 timestamp;
u32 type_specific_data;
struct mlo_timestamp m_timestamp;
but if so, that is less than clear from the code and declarations

I believe the above code would be much clearer if skb->data was typecast
to a struct pointer and assignments referenced members of the struct,
just like most/all of the functions that follow.
and as I've written before, I further believe that having accessor
functions/macros would make it even clearer.

could just unconditionally have pubsta = peer ? peer->sta : NULL
then initializer would be unnecessary

(reviewing this out of order since I saw strange usage in dp_rx.c review)
the above struct seems to be a host-only struct that is only written by
ath12k_copy_to_delay_stats() and only read by ath12k_copy_to_bar().
Therefore use of __packed seems unnecessary, especially since due to the
layout that will cause many members to be unaligned. In addition the
reserved0 member is not used, and since this is a host-only struct, is
unnecessary.
an alternative implementation would be to use the actual hardware
definition here, struct htt_ppdu_stats_user_rate, and then functions
ath12k_copy_to_delay_stats() and ath12k_copy_to_bar() could be simple
struct assignments.

since everything used to create hw_map_val[] is invariant, why not just
have a static const array of the final values and get rid of the loop above?

it seems strange to call a 2-bit field a flag

and it seems strange to have an enum which incorporates the values of
the ATH12K_HTC_CONN_FLAGS_THRESHOLD_LEVEL_MASK along with definitions of
other mask flags.
perhaps these would be more logically defined as macros just after
ATH12K_HTC_CONN_FLAGS_THRESHOLD_LEVEL_MASK:
#define ATH12K_HTC_CONN_FLAGS_THRESHOLD_LEVEL_MASK GENMASK(1, 0)
#define ATH12K_HTC_CONN_FLAGS_REDUCE_CREDIT_DRIBBLE BIT(2)
#define ATH12K_HTC_CONN_FLAGS_DISABLE_CREDIT_FLOW_CTRL BIT(3)
and then rename ath12k_htc_conn_flags to be more specific that it just
has threshold level values?

is there a reason this isn't msg_svc_id to be consistent with the other
htc messages?
or even have every htc msg begin with a struct ath12k_htc_msg hdr?
perhaps also consider some naming conventions similar to what were
adopted for WMI?

but this struct makes no sense. you can't have a variable-length payload
that isn't at the end of the struct
if this is just supposed to be some sort of pseudo-documentation then
perhaps put it in a comment so that the compiler won't see this?
or perhaps even better draw an ASCII representation?

seems this should be const
but for some reason struct mhi_controller_config has:
struct mhi_event_config *event_cfg;
(not const) so this can't be const :(
perhaps someone can propose a MHI interface change?
especially since internally to MHI in parse_ev_cfg() we have:
const struct mhi_event_config *event_cfg;
[...]
for (i = 0; i < num; i++) {
event_cfg = &config->event_cfg[i];
so it is treated as const

and this one should be const since it is registered via:

it seems strange/asymetrical to destroy this here.
it was allocated in ath12k_core_alloc() so I'd expect it to be destroyed
in ath12k_core_free() to maintain symmetry
in addition I don't see ab->workqueue being destroyed, and imo that
should also take place in ath12k_core_free() for the same reason

then the following typecast in pci.c would not be necessary:
static const struct ath12k_msi_config ath12k_msi_config[] = {
{
[...]
.users = (struct ath12k_msi_user[]) {
[...]

the other ath12k_peer_find_*() functions expect the caller to take the
lock, but in this one the function itself takes the lock. why the
discrepancy? should these have a consistent interface? note that the
returned peer won't be protected by the lock.
note i see this is only used in one place, and there it doesn't use the
peer, it just checks if it exists.
perhaps rename this to bool ath12k_peer_exists_by_vdev() to justify the
difference in locking?

curious why the above two structs use __le32 definitions but none of the
others do. I thought the QMI interface would use the qmi_elem_info to
properly encode/decode in host order on both sides of the pipe and hence
we should expect host order on both sides

I notice an inconsistency in logging, and wonder if there should be
consistency. Some commands have a debug log after ath12k_wmi_cmd_send()
and some have a debug log before:

in the case where an error is reported I think it would make more sense
to have the error log after the debug log.
For the "after" case above, in the error path, you'd have logs:
failed to submit WMI_VDEV_CREATE_CMDID
WMI vdev create: id %d type %d subtype %d macaddr %pM pdevid %d
IMO this is confusing since it tells you it failed, but then seems to be
telling you it did somethig
For the "before" case above, in the error path, you'd have:
WMI peer delete vdev_id %d peer_addr %pM
failed to send WMI_PEER_DELETE cmd
This seems to make more sense since it tells you it is doing something
and then tells you that what it was trying to do failed. no ambiguity.

FYI I've submitted a patch which will allow these to be const:

Good catch, we'll fix those and the missing __packed. Thanks for the review!

Originally, I would like to say the memcpy() statement can be replaced by
arg->ppet = ev->ppet;
But I found the struct(s) are different:
arg->ppet is
struct ath12k_wmi_ppe_threshold_arg {
u32 numss_m1;
u32 ru_bit_mask;
u32 ppet16_ppet8_ru3_ru0[PSOC_HOST_MAX_NUM_SS];
};
ev->ppet is
struct ath12k_wmi_ppe_threshold_params {
__le32 numss_m1; /** NSS - 1*/
union {
__le32 ru_count;
__le32 ru_mask;
} __packed;
__le32 ppet16_ppet8_ru3_ru0[WMI_MAX_NUM_SS];
} __packed;
Then, using memcpy() doesn't work on big-endian machine.

and, these two.
It seems like we don't have a simple way to convert struct with __le32 to
another struct with cpu order. The only way is to convert fields of struct
one by one.

Not sure why 'uint32_t'? Maybe, just '4' like other wmi functions.
mac80211 defines
struct ieee80211_key_conf {
u8 key[];
};
And, this driver defines
struct wmi_vdev_install_key_arg {
const void *key_data;

If arg->key_len wasn't align of 4, this could access out of range of arg->key_data.

I think '= 0' can be initializer like other functions.

That’s right. We use this function to get new ids starting from 0. So if an id is already
used (indicated by is_valid_peer_id) we move to the next id and return it and the
caller would set the is_valid_peer_id for that id and mark it.

The reo_cmd_cache_flush_list is used in only two contexts, one is this
Function called from napi and the other in ath12k_dp_free during
core destroy. Before dp_free, the irqs would be disabled and would wait
synchronize. Hence there wouldn’t be any race against add or delete
to this list. Please let me know if that’s fine.

We reset the whole struct once, and reset the necessary fields alone for every loop within ath12k_dp_rx_h_ppdu or similar places as necessary
and pass the status to mac80211.
The initial reset is necessary so as to reset all unused fields. This is an optimization to not memset the struct for every loop.

understand. so create an ieee80211_frag_number() function in ieee80211.h

please add that as a code comment since unlock/do something/lock is a
"code smell" so you should justify the smell

Hi Jeff
Thanks for your review..
Although, rx and tx mon rings processing blocks can be moved to common
function, this causes lot of variables to be sent to function using pass
by reference, hence avoiding this gerrit for tradeoff. Please let me
know if this is ok?
I will address rest of the comments in next revision of patch.
Thanks

yes, that is ok. it is always a tradeoff and different folks will weigh
the tradeoffs differently, and nobody is "right". As log as the code
works :)

Right. That could be added and used here,

The hw_cc indicates Hw cookie conversion, which converts the
cookie passed in the rxdma descriptor to a corresponding SW descriptor vaddr
(which was allocated mapped during init time in ath12k_dp_cc_init())
and passes back the addr directly during msdu rx rather than having
the idr overhead.
Since 'cc' was used across the driver to indicate this feature, we used it similarly
here as well.
Thanks,

But there's still more of these:
ce.h:138: struct sk_buff *skb[0];
core.h:738: u8 drv_priv[0] __aligned(sizeof(void *));
dp.h:1336: u8 data[0];
dp.h:1341: u8 value[0];
dp.h:1597: u8 payload[0];
rx_desc.h:1397: u8 msdu_payload[0];
rx_desc.h:1418: u8 msdu_payload[0];
I added these to my todo list, need to investigate in detail.

Back in the early ath10k days these enums were actually usign BIT() but
someone suggested to switch using hex numbers directly, just because
it's faster to calculate the debug mask. And I have to agree with that,
it's a lot easier when these are in hex.

That's a good question, I added it to my todo list.

P Praneesh fixed this:

Yeah, in general that would be good. But in this case it would also help
if struct hal_rx_user_status word0 and word1 fields would be renamed to
better reflect what they actually are:
u32 ul_ofdma_user_v0_word0;
u32 ul_ofdma_user_v0_word1;

Having a comment explaining what hw_cc means would be really nice.

It would be good to document such optimisations with a comment,
otherwise people might be confused.

Fixed. But now that I think it more, does setting it to NULL help? The
kernel will crash anyway if we try to access it, and if our code is so
buggy that it tries to do a double free it should warn about that anyway :)

Indeed, mac.c is 7000 lines long. We should consider refactoring it to
smaller files at some point.

You submitted a patch for this, thanks for that:
https://lore.kernel.org/all/[email protected]/
But oddly I cannot find anywhere in git, I sent a question about that to
the mhi list.

But I couldn't figure out how to remove the cast, I got compiler errors
whatever I tried. I added to todo and will revisit later.

That is a good question, I was also expecting QMI to be in host order.
In ce.h I see this:
/* Establish a mapping between a service/direction and a pipe.
* Configuration information for a Copy Engine pipe and services.
* Passed from Host to Target through QMI message and must be in
* little endian format.
*/
struct service_to_pipe {
__le32 service_id;
__le32 pipedir;
__le32 pipenum;
};
But I'm not convinced about that comments. Thoughts?

This is now fixed like this:
arg->ppet.numss_m1 = le32_to_cpu(ev->ppet.numss_m1);
arg->ppet.ru_bit_mask = le32_to_cpu(ev->ppet.ru_info);
for (i = 0; i < PSOC_HOST_MAX_NUM_SS; i++)
arg->ppet.ppet16_ppet8_ru3_ru0[i] =
le32_to_cpu(ev->ppet.ppet16_ppet8_ru3_ru0[i]);
But now the code assumes that both PSOC_HOST_MAX_NUM_SS and
WMI_MAX_NUM_SS are 8, which is not a safe assumption without a proper
check. I think the best would be to remove PSOC_HOST_MAX_NUM_SS and use
MAX_HE_NSS everywhere. I added that to the todo list.
