Subject: [PATCH net-next 0/6] r8169: disable ASPM during NAPI poll
Date: Mon, 6 Mar 2023 22:17:28 +0100 [thread overview]
Message-ID: <b434a0ce-9a76-e227-3267-ee26497ec446@gmail.com> (raw)
This is a rework of ideas from Kai-Heng on how to avoid the known
ASPM issues whilst still allowing for a maximum of ASPM-related power
savings. As a prerequisite some locking is added first.
Heiner Kallweit (6):
r8169: use spinlock to protect mac ocp register access
r8169: use spinlock to protect access to registers Config2 and Config5
r8169: enable cfg9346 config register access in atomic context
r8169: prepare rtl_hw_aspm_clkreq_enable for usage in atomic context
r8169: disable ASPM during NAPI poll
r8169: remove ASPM restrictions now that ASPM is disabled during NAPI
poll
