      [PATCH] genirq: cleanup: remove irq_descp() · a8553acd
      Ingo Molnar authored
      
      
      Cleanup: remove irq_descp() - explicit use of irq_desc[] is shorter and more
      readable.

      Consolidation: remove the irq_affinity[NR_IRQS] array and move it into the

      [PATCH] genirq: rename desc->handler to desc->chip · d1bef4ed
      Ingo Molnar authored
      
      
      This patch-queue improves the generic IRQ layer to be truly generic, by adding
      various abstractions and features to it, without impacting existing
      functionality.
      
      While the queue can be best described as "fix and improve everything in the
      generic IRQ layer that we could think of", and thus it consists of many
      smaller features and lots of cleanups, the one feature that stands out most is
      the new 'irq chip' abstraction.
      
      The irq-chip abstraction is about describing and coding and IRQ controller
      driver by mapping its raw hardware capabilities [and quirks, if needed] in a
      straightforward way, without having to think about "IRQ flow"
      (level/edge/etc.) type of details.
      
      This stands in contrast with the current 'irq-type' model of genirq
      architectures, which 'mixes' raw hardware capabilities with 'flow' details.
      The patchset supports both types of irq controller designs at once, and
      converts i386 and x86_64 to the new irq-chip design.
      
      As a bonus side-effect of the irq-chip approach, chained interrupt controllers
      (master/slave PIC constructs, etc.) are now supported by design as well.
      
      The end result of this patchset intends to be simpler architecture-level code
      and more consolidation between architectures.
      
      We reused many bits of code and many concepts from Russell King's ARM IRQ
      layer, the merging of which was one of the motivations for this patchset.
      
      This patch:
      
      rename desc->handler to desc->chip.
      
      Originally i did not want to do this, because it's a big patch.  But having
      both "desc->handler", "desc->handle_irq" and "action->handler" caused a
      large degree of confusion and made the code appear alot less clean than it
      truly is.
      
      I have also attempted a dual approach as well by introducing a
      desc->chip alias - but that just wasnt robust enough and broke
      frequently.
      
      So lets get over with this quickly.  The conversion was done automatically
      via scripts and converts all the code in the kernel.
      
      This renaming patch is the first one amongst the patches, so that the
      remaining patches can stay flexible and can be merged and split up
      without having some big monolithic patch act as a merge barrier.

      [IA64] support for cpu0 removal · ff741906
      Ashok Raj authored
      
      
      here is the BSP removal support for IA64. Its pretty much the same thing that
      was released a while back, but has your feedback incorporated.
      
      - Removed CONFIG_BSP_REMOVE_WORKAROUND and associated cmdline param
      - Fixed compile issue with sn2/zx1 due to a undefined fix_b0_for_bsp
      - some formatting nits (whitespace etc)
      
      This has been tested on tiger and long back by alex on hp systems as well.

      [PATCH] x86/x86_64: deferred handling of writes to /proc/irqxx/smp_affinity · 54d5d424
      Ashok Raj authored
      
      
      When handling writes to /proc/irq, current code is re-programming rte
      entries directly. This is not recommended and could potentially cause
      chipset's to lockup, or cause missing interrupts.
      
      CONFIG_IRQ_BALANCE does this correctly, where it re-programs only when the
      interrupt is pending. The same needs to be done for /proc/irq handling as well.
      Otherwise user space irq balancers are really not doing the right thing.
      
      - Changed pending_irq_balance_cpumask to pending_irq_migrate_cpumask for
        lack of a generic name.
      - added move_irq out of IRQ_BALANCE, and added this same to X86_64
      - Added new proc handler for write, so we can do deferred write at irq
        handling time.
      - Display of /proc/irq/XX/smp_affinity used to display CPU_MASKALL, instead
        it now shows only active cpu masks, or exactly what was set.
      - Provided a common move_irq implementation, instead of duplicating
        when using generic irq framework.
      
      Tested on i386/x86_64 and ia64 with CONFIG_PCI_MSI turned on and off.
      Tested UP builds as well.
      
      MSI testing: tbd: I have cards, need to look for a x-over cable, although I
      did test an earlier version of this patch.  Will test in a couple days.

      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!
