[PATCH 00/23] ath9k|ath9k_htc: move dups to common-beacon

[PATCH 00/23] ath9k|ath9k_htc: move dups to common-beacon

[Oleksij Rempel]

Next patch set. It removes only easy duplicats of beacon code. Other parts of
need deeper rework to make it compatible with ath9k.

Oleksij Rempel (23):
  ath9k: move struct ath_beacon_config to common
  ath9k_htc: use common ath_beacon_config
  ath9k_htc: move beaconq to struct htc_beacon
  ath9k_htc: use ath_beacon_conf.enable_beacon
  ath9k: move sc_flags to ath_common
  ath9k_htc: use common->op_flags
  ath9k_htc: add ATH_OP_PRIM_STA_VIF
  ath9k: remove unused bc_tstamp
  ath9k_htc: sync beacon slot code with ath9k
  ath9k: remove unused beacon_qi
  ath9k|ath9k_htc: move IEEE80211_MS_TO_TU to common
  ath9k-common: add nexttbtt and intval to ath_beacon_config
  ath9k: move ath9k_beacon_config_sta to common-beacon
  ath9k_htc: use ath9k_cmn_beacon_config_sta
  ath9k: move ath9k_beacon_config_adhoc to common
  ath9k_htc: add ath9k_htc_beacon_init (but not use it)
  ath9k_htc: use ath9k_htc_beacon_init in ath9k_htc_beacon_config_ap
  ath9k_htc: use ath9k_htc_beacon_init in ath9k_htc_beacon_config_adhoc
  ath9k_htc: use ath9k_cmn_beacon_config_adhoc
  ath9k: move ath9k_beacon_config_ap common
  ath9k: remove unused ath9k_get_next_tbtt
  ath9k_htc: use ath9k_cmn_beacon_config_ap
  ath9k_htc: move DEFAULT_SWBA_RESPONSE check to ath9k_htc_beacon_init

Re: [PATCH 00/23] ath9k|ath9k_htc: move dups to common-beacon

[Sujith Manoharan]

Hi,

Lots of code churn. :)

Maybe reusing ath9k entirely and just writing a USB layer can
be a better approach ?

I was thinking about it too, but suddenly i don't have enough time and
experience to do it. Beside, there is no need to write usb layer. It is
clean and separate from other part of the driver. But the HTC/WMI
interface is not completely separate.
In this case ath9k driver will need some rework too. For example
beacon.c code works directly with DMA queues, see "struct ath_beacon".
May be it is still better to add needed changes in ath9k by keeping
ath9k_htc functional.

Now about bigger picture. Right now i work only on ath9k<>ath9k_htc
dups. But there are lots of dup code in ath9k itself. For example
*_phy.c, *_initvals.h. Here are some examples:

If some one can take care of it, it will be great :)

The programm i use (scitools Understand), found 14851 lines of
Duplicated code in wireless/ath. Probably there are some false positive
and code which was not found because of some cosmetic changes.

I assume that usb code can be reused can be same on ar5523, carl9170,
ath9k_htc. And some WMI code at least on ath10k and ath9k_htc.

Sure. It is just another option to consider.

We already have duplicate detection for initvals. It is part of

So, where does this leave us?  Should this series be merged?  Or not?

Last response was about initvals, my patch set affect only beacon code.
Since i don't plan to rewrite ath9k_htc from scratch, i would assume it
will be better to continue this periodic clean work.

Sujith, are you agree? :) We need your Ack for this patch set.

I didn't review the patches, but someone else needs to make sure that
nothing is broken in ath9k.

I use this code one week ind STA mode. But if you need more directed
alternate testing, who is good candidate for this work?
