      [PATCH] x86_64: Support for AMD specific MCE Threshold. · 89b831ef
      Jacob Shin 提交于
      MC4_MISC - DRAM Errors Threshold Register realized under AMD K8 Rev F.
      This register is used to count correctable and uncorrectable ECC errors that occur during DRAM read operations.
      The user may interface through sysfs files in order to change the threshold configuration.
      
      bank%d/error_count - reads current error count, write to clear.
      bank%d/interrupt_enable - set/clear interrupt enable.
      bank%d/threshold_limit - read/write the threshold limit.
      
      APIC vector 0xF9 in hw_irq.h.
      5 software defined bank ids in mce.h.
      new apic.c function to setup threshold apic lvt.
      defaults to interrupt off, count enabled, and threshold limit max.
      sysfs interface created on /sys/devices/system/threshold.
      
      AK: added some ifdefs to make it compile on UP

      [LIB]: Consolidate _atomic_dec_and_lock() · 4db2ce01
      David S. Miller 提交于
      Several implementations were essentialy a common piece of C code using
      the cmpxchg() macro.  Put the implementation in one spot that everyone
      can share, and convert sparc64 over to using this.
      
      Alpha is the lone arch-specific implementation, which codes up a
      special fast path for the common case in order to avoid GP reloading
      which a pure C version would require.

      [PATCH] Kconfig fix (BLK_DEV_FD dependencies) · a08b6b79
      viro@ZenIV.linux.org.uk 提交于
      Sanitized and fixed floppy dependencies: split the messy dependencies for
      BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making
      BLK_DEV_FD depend on that one and taking declarations of ARCH_MAY_HAVE_PC_FDC
      to arch/*/Kconfig.  While we are at it, fixed several obvious cases when
      BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h
      are *not* going to have floppy.c compile, let alone work).
      
      If you can come up with better name for that ("this architecture might
      have working PC-compatible floppy disk controller"), you are more than
      welcome - just s/ARCH_MAY_HAVE_PC_FDC/your_prefered_name/g in the patch
      below...

      [PATCH] x86/x86_64: deferred handling of writes to /proc/irqxx/smp_affinity · 54d5d424
      Ashok Raj 提交于
      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.

      [NET]: add a top-level Networking menu to *config · d5950b43
      Sam Ravnborg 提交于
      Create a new top-level menu named "Networking" thus moving
      net related options and protocol selection way from the drivers
      menu and up on the top-level where they belong.
      
      To implement this all architectures has to source "net/Kconfig" before
      drivers/*/Kconfig in their Kconfig file. This change has been
      implemented for all architectures.
      
      Device drivers for ordinary NIC's are still to be found
      in the Device Drivers section, but Bluetooth, IrDA and ax25
      are located with their corresponding menu entries under the new
      networking menu item.

      [PATCH] Note on ACPI build fix · 8aadff7d
      Alexander Nyberg 提交于
      Even after the previous fix you can still set CONFIG_ACPI_BOOT
      indirectly even without CONFIG_ACPI by choosing CONFIG_PCI and
      CONFIG_PCI_MMCONFIG.
      
      That doesn't build very well either.
      
      This makes PCI_MMCONFIG depend on ACPI, fixing that hole.
      
      [ I guess in theory Kconfig could follow the whole chain of dependencies
        for things that get selected, but that sounds insanely complicated, so
        we'll just fix up these things by hand.  --Linus ]

      [PATCH] x86_64: Add pmtimer support · 312df5f1
      Andi Kleen 提交于
      There are unfortunately more and more multi processor Opteron systems which
      don't have HPET timer support in the southbridge.  This covers in particular
      Nvidia and VIA chipsets.  They also don't guarantee that the TSCs are
      synchronized between CPUs; and especially with MP powernow the systems are
      nearly unusable because the time gets very inconsistent between CPUs.
      
      The timer code for x86-64 was originally written under the assumption that we
      could fall back to the HPET timer on such systems.  But this doesn't work
      there.
      
      Another alternative is to use the ACPI PM timer as primary time source.  This
      patch does that.  The kernel only uses PM timer when there is no other choice
      because it has some disadvantages.
      
      Ported over from i386.  It should be faster than the i386 version because I
      dropped the "read three times" workaround, but is still considerable slower
      than HPET and also does not work together with vsyscalls which have to be
      disabled.

      [PATCH] ISA DMA Kconfig fixes - part 1 · 5cae841b
      Al Viro 提交于
      A bunch of drivers use ISA DMA helpers or their equivalents for
      platforms that have ISA with different DMA controller (a lot of ARM
      boxen).  Currently there is no way to put such dependency in Kconfig -
      CONFIG_ISA is not it (e.g.  it is not set on platforms that have no ISA
      slots, but have on-board devices that pretend to be ISA ones).
      
      New symbol added - ISA_DMA_API.  Set when we have functional
      enable_dma()/set_dma_mode()/etc.  set of helpers.  Next patches in the
      series will add missing dependencies for drivers that need them.
      
      I'm very carefully staying the hell out of the recurring flamefest on
      what exactly CONFIG_ISA would mean in ideal world - added symbol has a
      well-defined meaning and for now I really want to treat it as completely
      independent from the mess around CONFIG_ISA.

      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!
