Subject: [RFC v1 00/25] Optimize irq flow handler
Date: Wed, 20 May 2015 17:59:48 +0800 [thread overview]
Message-ID: <1432116013-25902-1-git-send-email-jiang.liu@linux.intel.com> (raw)
This is an patch set to optimize irq flow handler. It could be split
into three part.
1) Patch 1-12 get rid of redundant looking up of irq_desc and irq_data
when we already had an pointer to corresponding irq_desc in irq
flow handler. This part should be pretty safe.
2) Patch 13 is a perparation patch.
3) Patch 14-25 should be merge into one big fat patch, which kills
the first parameter 'irq' of irq_flow_handler_t. I hope I have
made all needed changes, but there are still some handler missed.
After the conversion, there are only about 20 irq handlers which
really access the irq number. This part is still in early stage
and may cause building failures.
Please comment on whether we should be go on with the third part to
kill 'irq' of irq_flow_handler_t.
Thanks!
Gerry
