Subject: Re: [PATCH wireless-next] wifi: brcmfmac: allow opting into PM_MAX power management
Date: Fri, 14 Aug 2026 22:51:15 +0200 [thread overview]
Message-ID: <20260814205115.799977-1-alexander@fischermail.me> (raw)

Hello,
I would like to withdraw this patch.
Further testing on BCM4364 showed intermittent latency spikes of about
50-250 ms with PM_MAX. The connection can work normally for extended
periods, but the issue is reproducible and disappears after switching
back to PM_FAST. This invalidates my earlier statement that I had
observed no latency regression.
Given this trade-off, I no longer think exposing PM_MAX through this new
module parameter is worthwhile, and I do not plan to send a v2. Please
drop the patch.
pw-bot: changes-requested
Sorry for the noise, and thanks for your time.
Regards,
Alexander
