Subject: [PATCH 0/4 V3 net-next] net: mana: Assigning IRQ affinity on HT cores
Date: Sun, 28 Jan 2024 22:21:03 -0800 [thread overview]
Message-ID: <1706509267-17754-1-git-send-email-schakrabarti@linux.microsoft.com> (raw)

to optimize IRQ distribution for MANA network devices.
The patch set makes the driver working 15% faster than
with cpumask_local_spread().
Souradeep Chakrabarti (1):
net: mana: Assigning IRQ affinity on HT cores
Yury Norov (3):
cpumask: add cpumask_weight_andnot()
cpumask: define cleanup function for cpumasks
net: mana: add a function to spread IRQs per CPUs
