Use kstrtoul_from_user() for reading the user value,
and fix the following sparse warning:

sta_rc_update runs in atomic context. thus, a new work
should be scheduled in order to configure the fw
with the required configuration.

Add the ability to mask FW interrupts on RX BA activity, PSM
entry/exit and fast-link notifications. This is used when the host
is suspended in order to decrease redundant wake ups.

configure wowlan when host is suspended in AP mode,
since the FW can now wake the host up on Rx.

Enable ELP authorization in AP mode and enable the use
of the wakeup bit in the ELP register.

Introduce AP role sleep configuration which is disabled
by default. When configured, it allows the AP to sleep
when ELP is authorized for it.

This patch requires a new firmware, loading of "wl18xx-conf.bin" from

thanks. seems you're right.

anyway, note that this file is not actual fw, but only the default
configuration params.
you can just delete it, and the driver will load just fine.
you can then recreate it with something like:
cat /sys/kernel/debug/ieee80211/phy0/wlcore/wl18xx/conf >
/lib/firmware/ti-connectivity/wl18xx-conf.bin

actually, i don't think it makes much sense to have this file in the
linux-firmware git at all.
i'll try handling it.

Eliad.

Thanks, there are more file with size of ~1k, are they optional, too?
What's the "error" message if these optional files are not present?

From working with $CUSTOMERS I gained the impression, messages like
"error failed to load...." for optional file don't shine the best light
on Linux, a neutral "using default values" is far better.

Marc

AFAIK, the other nvs files are basically required for proper operation.

Any update on the wl18xx-conf.bin issue? This file is still in
linux-firmware repo.

I have following problem. My Jorjin chip requires wl18xx-conf.bin
compiled from special *.ini file.
https://github.com/TI-OpenLink/18xx-ti-utils/tree/master/wlconf
doesn't seem to support v4 firmware as it creates 1221 bytes conf
file. Where can I get proper wlconf and companion files
(dictionary.txt, struct.bin etc.)?

thanks for the reminder :)

just sent a patch to fallback to default conf in case of invalid/outdated conf.

Great.

@Yaniv: but how to create a new conf with 1226 bytes for existing ini file?

From: Eliad Peller @ 2014-12-29  6:24 UTC (permalink / raw)
  To: linux-wireless

Add support for CAC start/stop commands, and pass
radar detection events from the fw to mac80211.

Bump fw name (to wl18xx-fw-4.bin) and min fw version
(to 8.9.*.*.11), and align event mailbox accordingly.

call wlcore_cmd_dfs_master_restart when starting
the ap on a new channel (after csa is done).

Add a new WLVIF_FLAG_BEACON_DISABLED flag to
indicate that dfs_master_restart command
is required.

Since we are going to support dfs channels, there
is no reason to mark them as NO_IR (having
the DFS flag is enough anyway).

Additionally, when setting the regdomain configuration,
enable usable dfs channels.
