Appreciate your efforts!

Just trying to make sure it does not get lost.
Introduced in rc1, not fixed by ... rc4.

Anyway, I will continue to test, lots of other things still to chase
even in rc4!

Regards,

Ross Green

The commit 3719c17e1816 ("wlcore/wl18xx: fw logger over sdio") introduced a
regression causing the wlcore to time out and go into recovery. Reverting the
changes regarding write of the last partition size brings the module back to
it's functional state.

Thanks, applied to wireless-drivers.git.

I just tested linux-4.5-rc4 it appears the above fix missed the release for rc4!
So the behaviour of firmware reset being called after the access of
the last partition timesout.

Again tested patch with the new release - 4.5-rc4 and found everything
to work as expected again.

So Hopefully for rc5 - Please!

It takes some time to get patches into Linus' tree. And being in a
conference and then getting sick is not really helping. I'm not sure if
this patch makes to rc5 on time, but I'll try.

G'day all,

I have tested Emil's patch with each 4.5-rc release.

Seems to work fine with rc2, rc3, rc4.
I tried it with rc5 and get the following output from dmesg see attachment.

So it looks like there is a reset that it recovers from and then proceeds OK.

I see the patch has been queued by David Miller so it might make it into rc6.
That will be great. It still does not look quite as clean as it should
be however, given the noise in the dmesg output from rc5

Regards,


Ross Green

I'm unable to reproduce that ELP wakeup timeout with v4.5-rc5 on my pandaboard es.
Can you easily reproduce it and are you able to reproduce it with commit 3719c17e1816 reverted?

However, I'm seeing another bug that occurs when the wlan is not configured to connect to
an AP directly after boot (dmesg attached). It is not related to any recent changes and goes back
before the 3.14 kernel. There seem to be an issue with the looped IRQ handling implementation.
A scan on 2GHZ is performed and the wlcore_fw_status() call in wlcore_irq_locked() returns
WL1271_ACX_INTR_HW_AVAILABLE, then nothing seem to happen until the delayed work queue
scan_complete_work starts executing after the 30 sec timeout runs out and the wlcore goes into
recovery. I guess a new scan should be initiated after wlcore_fw_status() return hw available,
does anyone have input on that?

Best regards,

Emil Goode
