2009-01-29Documentation: move DMA-mapping.txt to Doc/PCI/Randy Dunlap
Move DMA-mapping.txt to Documentation/PCI/. DMA-mapping.txt was supposed to be moved from Documentation/ to Documentation/PCI/. The 00-INDEX files in those two directories were updated, along with a few other text files, but the file itself somehow escaped being moved, so move it and update more text files and source files with its new location.

2009-01-16kprobes: check CONFIG_FREEZER instead of CONFIG_PMMasami Hiramatsu
Check CONFIG_FREEZER instead of CONFIG_PM because kprobe booster depends on freeze_processes() and thaw_processes() when CONFIG_PREEMPT=y. This fixes a linkage error which occurs when CONFIG_PREEMPT=y, CONFIG_PM=y and CONFIG_FREEZER=n.

Create a platform specific version of dma_get_required_mask() for ia64 SN Altix. All SN Altix platforms support 64 bit DMA addressing regardless of the size of system memory.

2009-01-15[IA64] dump stack on kernel unaligned warningsDoug Chapman
Often the cause of kernel unaligned access warnings is not obvious from just the ip displayed in the warning. This adds the option via proc to dump the stack in addition to the warning. The default is off (just display the 1 line warning).

2009-01-15[IA64] Turn on CONFIG_HAVE_UNSTABLE_CLOCKTony Luck
sched_clock() on ia64 is based on ar.itc, so is never completely synchronized between cpus. On some platforms (e.g. certain models of SGI Altix) it may be running at radically different frequencies. Based on a patch from Dimitri Sivanich which set this just for SN2 && GENERIC kernels ... it is needed for all ia64 machines. Signed-off-by: Tony Luck <tony.luck@intel.com>

2009-01-06mm: show node to memory section relationship with symlinks in sysfsGary Hade
Show node to memory section relationship with symlinks in sysfs Add /sys/devices/system/node/nodeX/memoryY symlinks for all the memory sections located on nodeX. For example: /sys/devices/system/node/node1/memory135 -> ../../memory/memory135 indicates that memory section 135 resides on node1. Also revises documentation to cover this change as well as updating Documentation/ABI/testing/sysfs-devices-memory to include descriptions of memory hotremove files 'phys_device', 'phys_index', and 'state' that were previously not described there. In addition to it always being a good policy to provide users with the maximum possible amount of physical location information for resources that can be hot-added and/or hot-removed, the following are some (but likely not all) of the user benefits provided by this change. Immediate: - Provides information needed to determine the specific node on which a defective DIMM is located. This will reduce system downtime when the node or defective DIMM is swapped out. - Prevents unintended onlining of a memory section that was previously offlined due to a defective DIMM. This could happen during node hot-add when the user or node hot-add assist script onlines _all_ offlined sections due to user or script inability to identify the specific memory sections located on the hot-added node. The consequences of reintroducing the defective memory could be ugly. - Provides information needed to vary the amount and distribution of memory on specific nodes for testing or debugging purposes. Future: - Will provide information needed to identify the memory sections that need to be offlined prior to physical removal of a specific node. Symlink creation during boot was tested on 2-node x86_64, 2-node ppc64, and 2-node ia64 systems. Symlink creation during physical memory hot-add tested on a 2-node x86_64 system.

2009-01-01cpumask: Introduce topology_core_cpumask()/topology_thread_cpumask(): ia64Rusty Russell
Impact: New API The old topology_core_siblings() and topology_thread_siblings() return a cpumask_t; these new ones return a (const) struct cpumask *. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com>
2009-01-01cpumask: Remove IA64 definition of total_cpus now it's in core codeRusty Russell
Impact: fix IA64 compile Fortunately, they have exactly the same semantics. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2008-12-31KVM: ia64: Fix kvm_arch_vcpu_ioctl_[gs]et_regs()Jes Sorensen
Fix kvm_arch_vcpu_ioctl_[gs]et_regs() to do something meaningful on ia64. Old versions could never have worked since they required pointers to be set in the ioctl payload which were never being set by the ioctl handler for get_regs. In addition reserve extra space for future extensions. The change of layout of struct kvm_regs doesn't require adding a new CAP since get/set regs never worked on ia64 until now. This version doesn't support copying the KVM kernel stack in/out of the kernel. This should be implemented in a seperate ioctl call if ever needed.

2008-12-31KVM: ia64: Add handler for crashed vmmXiantao Zhang
Since vmm runs in an isolated address space and it is just a copy of host's kvm-intel module, so once vmm crashes, we just crash all guests running on it instead of crashing whole kernel. Signed-off-by: Xiantao Zhang <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2008-12-31KVM: ia64: Define printk function for kvm-intel moduleXiantao Zhang
kvm-intel module is relocated to an isolated address space with kernel, so it can't call host kernel's printk for debug purpose. In the module, we implement the printk to output debug info of vmm. Signed-off-by: Xiantao Zhang <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2008-12-31KVM: ia64: Remove lock held by halted vcpuXiantao Zhang
Remove the lock protection for kvm halt logic, otherwise, once other vcpus want to acquire the lock, and they have to wait all vcpus are waken up from halt. Signed-off-by: Xiantao Zhang <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2008-12-31KVM: ia64: Re-organize data sturure of guests' data areaXiantao Zhang
1. Increase the size of data area to 64M 2. Support more vcpus and memory, 128 vcpus and 256G memory are supported for guests. 3. Add the boundary check for memory and vcpu allocation. With this patch, kvm guest's data area looks as follow: * * +----------------------+ ------- KVM_VM_DATA_SIZE * | vcpu[n]'s data | | ___________________KVM_STK_OFFSET * | | | / | * | .......... | | /vcpu's struct&stack | * | .......... | | /---------------------|---- 0 * | vcpu[5]'s data | | / vpd | * | vcpu[4]'s data | |/-----------------------| * | vcpu[3]'s data | / vtlb | * | vcpu[2]'s data | /|------------------------| * | vcpu[1]'s data |/ | vhpt | * | vcpu[0]'s data |____________________________| * +----------------------+ | * | memory dirty log | | * +----------------------+ | * | vm's data struct | | * +----------------------+ | * | | | * | | | * | | | * | | | * | | | * | | | * | | | * | vm's p2m table | | * | | | * | | | * | | | | * vm's data->| | | | * +----------------------+ ------- 0 * To support large memory, needs to increase the size of p2m. * To support more vcpus, needs to ensure it has enough space to * hold vcpus' data. */ Signed-off-by: Xiantao Zhang <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
