strange behaviour from "make localmodconfig" throws out ath9k stuff

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



  probably a simple explanation for this, but my first time playing
with "make localmodconfig" and it appears to be tossing all my
ath9k-related module settings.

  currently running ubuntu on a 64-bit asus laptop with the following
ath9k-related modules:

$ lsmod | grep ath9k
ath9k                 149545  0
mac80211              558577  1 ath9k
ath9k_common           14054  1 ath9k
ath9k_hw              408874  2 ath9k,ath9k_common
ath                    23828  3 ath9k,ath9k_common,ath9k_hw
cfg80211              211955  3 ath9k,mac80211,ath
$

  starting with current kernel "git pull", i do:

$ make allmodconfig

at which point i get:

$ grep ATH9K .config
CONFIG_ATH9K_HW=m
CONFIG_ATH9K_COMMON=m
CONFIG_ATH9K_DFS_DEBUGFS=y
CONFIG_ATH9K_BTCOEX_SUPPORT=y
CONFIG_ATH9K=m
CONFIG_ATH9K_PCI=y
CONFIG_ATH9K_AHB=y
CONFIG_ATH9K_DEBUGFS=y
CONFIG_ATH9K_DFS_CERTIFIED=y
CONFIG_ATH9K_MAC_DEBUG=y
CONFIG_ATH9K_RATE_CONTROL=y
CONFIG_ATH9K_HTC=m
CONFIG_ATH9K_HTC_DEBUGFS=y
$

which looks reasonable(?).  then run:

$ make localmodconfig

have to answer maybe 4 questions manually, at which point i have:

$ grep ATH9K .config
$

that doesn't look good, i should definitely have module selections for
ath9k stuff, no?  and if i run that command again, i get:

$ make localmodconfig
using config: '.config'
WARNING: ATH9K_HW is required, but nothing in the
  current config selects it.
WARNING: ATH_COMMON is required, but nothing in the
  current config selects it.
WARNING: ATH9K_COMMON is required, but nothing in the
  current config selects it.
module ath9k did not have configs CONFIG_ATH9K
module uas did not have configs CONFIG_USB_UAS
module ath did not have configs CONFIG_ATH_COMMON
module ath9k_hw did not have configs CONFIG_ATH9K_HW
module ath9k_common did not have configs CONFIG_ATH9K_COMMON
#
# configuration written to .config
#
$

so there seems to be something related specifically to ath9k that
doesn't play well with "localmodconfig". or am i doing something
silly?
