Subject: [PATCH 00/04] dyn_array and nr_irqs support v3 -- addon
Date: Mon, 4 Aug 2008 03:09:57 -0700 [thread overview]
Message-ID: <1217844601-4298-1-git-send-email-yhlu.kernel@gmail.com> (raw)
use pre_allocate array and list to index struct with irq_no to avoid
wasting struct between irq
01: x86_64: use get_irq_desc together with dyn_array
02: x86: add get_irq_cfg in io_apic_64.c
03: x86: put timer_rand_state pointer into irq_desc
04: x86: put irq_2_pin pointer into irq_cfg - 64bit
got:
dyn_array irq_2_pin_head+0x0/0x8 size:0x10 nr:32 align:0x10
dyn_array irq_cfgx+0x0/0x8 size:0x120 nr:32 align:0x1000
dyn_array irq_desc+0x0/0x8 size:0x200 nr:32 align:0x1000
dyn_array irq_2_iommu+0x0/0x8 size:0x10 nr:96 align:0x1000
dyn_array total_size: 0x8200
dyn_array irq_2_pin_head+0x0/0x8 ==> [0x28028000 - 0x28028200]
dyn_array irq_cfgx+0x0/0x8 ==> [0x28029000 - 0x2802b400]
dyn_array irq_desc+0x0/0x8 ==> [0x2802c000 - 0x28030000]
dyn_array irq_2_iommu+0x0/0x8 ==> [0x28030000 - 0x28030600]
per_cpu_dyn_array per_cpu__kstat+0x48/0x50 size:0x4 nr:96 align:0x8
irq_cfg/irq_desc will increase by 32 automatically, and the use one by one.
to do:
1. will work ong irq_2_iommu: put it in irq_desc or irq_cfg?
2. will update Eric's patch to move kstat_irqs from per cpu to irq_desc...
3. after that will clean up nr_irqs, and try to kill it
Thanks
Yinghai Lu
