Subject: [PATCH 0/3] irq/core: Fix and expand the irq affinity descriptor
Date: Tue, 4 Dec 2018 23:51:19 +0800 [thread overview]
Message-ID: <20181204155122.6327-1-douliyangs@gmail.com> (raw)
Now, Spreading the interrupt affinity info by a cpumask pointer is not
enough, meets a problem[1] and hard to expand in the future.
Fix it by:
+-----------------------------------+
| |
| struct cpumask *affinity |
| |
+-----------------------------------+
|
+------------------v-------------------+
| |
| struct irq_affinity_desc { |
| struct cpumask mask; |
| unsigned int is_managed : 1; |
| }; |
| |
+--------------------------------------+
