      x86/apic: Handle XAPIC remap mode proper. · ef1b2b8a
      Jiang Liu authored
      If remapping is in XAPIC mode, the setup code just skips X2APIC
      initialization without checking max CPU APIC ID in system, which may
      cause problem if system has a CPU with APIC ID bigger than 255.
      
      Handle IR in XAPIC mode the same way as if remapping is disabled.

      x86/apic: Correctly detect X2APIC status in function enable_IR() · 89356cf2
      Jiang Liu authored
      X2APIC will be disabled if user specifies "nox2apic" on kernel command
      line, even when x2apic_preenabled is true. So correctly detect X2APIC
      status by using x2apic_enabled() instead of x2apic_preenabled.

      x86/apic: Panic if kernel doesn't support x2apic but BIOS has enabled x2apic · 2599094f
      Jiang Liu authored
      When kernel doesn't support X2APIC but BIOS has enabled X2APIC, system
      may panic or hang without useful messages. On the other hand, it's
      hard to dynamically disable X2APIC when CONFIG_X86_X2APIC is disabled.
      So panic with a clear message in such a case.

      x86/apic: Clear stale x2apic mode · f7ccadac
      Thomas Gleixner authored
      If x2apic got disabled on the kernel command line, then the following
      issue can happen:
      
      enable_IR_x2apic()
         ....
         x2apic_mode = 1;
         enable_x2apic();
      
           if (x2apic_disabled) {
      	__disable_x2apic();
      	return;
           }
      
      That leaves X2APIC disabled in hardware, but x2apic_mode stays 1. So
      all other code which checks x2apic_mode gets the wrong information.
      
      Set x2apic_mode to 0 after disabling it in hardware.
      
      This is just a hotfix. The proper solution is to rework this code so
      it has seperate functions for the initial setup on the boot processor
      and the secondary cpus, but that's beyond the scope of this fix.

      iommu/vt-d: Move iommu preparatory allocations to irq_remap_ops.prepare · 11190302
      Thomas Gleixner authored
      The whole iommu setup for irq remapping is a convoluted mess. The
      iommu detect function gets called from mem_init() and the prepare
      callback gets called from enable_IR_x2apic() for unknown reasons.
      
      Of course AMD and Intel setup differs in nonsensical ways. Intels
      prepare callback is explicit while AMDs prepare callback is implicit
      in setup_irq_remapping_ops() just to be called in the prepare call
      again.
      
      Because all of this gets called from enable_IR_x2apic() and the dmar
      prepare function merily parses the ACPI tables, but does not allocate
      memory we end up with memory allocation from irq disabled context
      later on.
      
      AMDs iommu code at least allocates the required memory from the
      prepare function. That has issues as well, but thats not scope of this
      patch.
      
      The goal of this change is to distangle the allocation from the actual
      enablement. There is no point to allocate memory from irq disabled
      regions with GFP_ATOMIC just because it does not matter at that point
      in the boot stage. It matters with physical hotplug later on.
      
      There is another issue with the current setup. Due to the conversion
      to stacked irqdomains we end up with a call into the irqdomain
      allocation code from irq disabled context, but that code does
      GFP_KERNEL allocations rightfully as there is no reason to do
      preperatory allocations with GFP_ATOMIC.
      
      That change caused the allocator code to complain about GFP_KERNEL
      allocations invoked in atomic context. Boris provided a temporary
      hackaround which changed the GFP flags if irq_domain_add() got called
      from atomic context. Not pretty and we really dont want to get this
      into a mainline release for obvious reasons.
      
      Move the ACPI table parsing and the resulting memory allocations from
      the enable to the prepare function. That allows to get rid of the
      horrible hackaround in irq_domain_add() later.

      iommu, x86: Restructure setup of the irq remapping feature · a1dafe85
      Thomas Gleixner authored
      enable_IR_x2apic() calls setup_irq_remapping_ops() which by default
      installs the intel dmar remapping ops and then calls the amd iommu irq
      remapping prepare callback to figure out whether we are running on an
      AMD machine with irq remapping hardware.
      
      Right after that it calls irq_remapping_prepare() which pointlessly
      checks:
      	if (!remap_ops || !remap_ops->prepare)
                     return -ENODEV;
      and then calls
      
          remap_ops->prepare()
      
      which is silly in the AMD case as it got called from
      setup_irq_remapping_ops() already a few microseconds ago.
      
      Simplify this and just collapse everything into
      irq_remapping_prepare().
      
      The irq_remapping_prepare() remains still silly as it assigns blindly
      the intel ops, but that's not scope of this patch.
      
      The scope here is to move the preperatory work, i.e. memory
      allocations out of the atomic section which is required to enable irq
      remapping.
