      bitmap, irq: add smp_affinity_list interface to /proc/irq · 4b060420
      Mike Travis authored
      Manually adjusting the smp_affinity for IRQ's becomes unwieldy when the
      cpu count is large.
      Setting smp affinity to cpus 256 to 263 would be:
      	echo 000000ff,00000000,00000000,00000000,00000000,00000000,00000000,00000000 > smp_affinity
      instead of:
      	echo 256-263 > smp_affinity_list
      Think about what it looks like for cpus around say, 4088 to 4095.
      We already have many alternate "list" interfaces:
      Add a companion interface, smp_affinity_list to use cpu lists instead of
      cpu maps.  This conforms to other companion interfaces where both a map
      and a list interface exists.
      This required adding a bitmap_parselist_user() function in a manner
      similar to the bitmap_parse_user() function.
      [akpm@linux-foundation.org: make __bitmap_parselist() static]

      genirq: Expose default irq affinity mask (take 3) · 18404756
      Max Krasnyansky authored
      Current IRQ affinity interface does not provide a way to set affinity
      for the IRQs that will be allocated/activated in the future.
      This patch creates /proc/irq/default_smp_affinity that lets users set
      default affinity mask for the newly allocated IRQs. Changing the default
      does not affect affinity masks for the currently active IRQs, they
      have to be changed explicitly.
      Updated based on Paul J's comments and added some more documentation.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      Let it rip!
