2009-03-24KVM: New guest debug interfaceJan Kiszka
This rips out the support for KVM_DEBUG_GUEST and introduces a new IOCTL instead: KVM_SET_GUEST_DEBUG. The IOCTL payload consists of a generic part, controlling the "main switch" and the single-step feature. The arch specific part adds an x86 interface for intercepting both types of debug exceptions separately and re-injecting them when the host was not interested. Moveover, the foundation for guest debugging via debug registers is layed. To signal breakpoint events properly back to userland, an arch-specific data block is now returned along KVM_EXIT_DEBUG. For x86, the arch block contains the PC, the debug exception, and relevant debug registers to tell debug events properly apart. The availability of this new interface is signaled by KVM_CAP_SET_GUEST_DEBUG. Empty stubs for not yet supported archs are provided. Note that both SVM and VTX are supported, but only the latter was tested yet. Based on the experience with all those VTX corner case, I would be fairly surprised if SVM will work out of the box.

2009-02-19[IA64] bte_copy of BTE_MAX_XFER trips BUG_ON.Robin Holt
BTE_MAX_XFER is wrong. It is one greater than the number of cache lines the BTE is actually able to transfer. If you request a transfer of exactly BTE_MAX_XFER size, you trip a very cryptic BUG_ON() which should certainly be made more clear. This patch fixes that constant and also cleans up the BUG_ON()s in arch/ia64/sn/kernel/bte.c to test one condition per line.

2009-02-18mm: clean up for early_pfn_to_nid()KAMEZAWA Hiroyuki
What's happening is that the assertion in mm/page_alloc.c:move_freepages() is triggering: BUG_ON(page_zone(start_page) != page_zone(end_page)); Once I knew this is what was happening, I added some annotations: if (unlikely(page_zone(start_page) != page_zone(end_page))) { printk(KERN_ERR "move_freepages: Bogus zones: " "start_page[%p] end_page[%p] zone[%p]\n", start_page, end_page, zone); printk(KERN_ERR "move_freepages: " "start_zone[%p] end_zone[%p]\n", page_zone(start_page), page_zone(end_page)); printk(KERN_ERR "move_freepages: " "start_pfn[0x%lx] end_pfn[0x%lx]\n", page_to_pfn(start_page), page_to_pfn(end_page)); printk(KERN_ERR "move_freepages: " "start_nid[%d] end_nid[%d]\n", page_to_nid(start_page), page_to_nid(end_page)); ... And here's what I got: move_freepages: Bogus zones: start_page[2207d0000] end_page[2207dffc0] zone[fffff8103effcb00] move_freepages: start_zone[fffff8103effcb00] end_zone[fffff8003fffeb00] move_freepages: start_pfn[0x81f600] end_pfn[0x81f7ff] move_freepages: start_nid[1] end_nid[0] My memory layout on this box is: [ 0.000000] Zone PFN ranges: [ 0.000000] Normal 0x00000000 -> 0x0081ff5d [ 0.000000] Movable zone start PFN for each node [ 0.000000] early_node_map[8] active PFN ranges [ 0.000000] 0: 0x00000000 -> 0x00020000 [ 0.000000] 1: 0x00800000 -> 0x0081f7ff [ 0.000000] 1: 0x0081f800 -> 0x0081fe50 [ 0.000000] 1: 0x0081fed1 -> 0x0081fed8 [ 0.000000] 1: 0x0081feda -> 0x0081fedb [ 0.000000] 1: 0x0081fedd -> 0x0081fee5 [ 0.000000] 1: 0x0081fee7 -> 0x0081ff51 [ 0.000000] 1: 0x0081ff59 -> 0x0081ff5d So it's a block move in that 0x81f600-->0x81f7ff region which triggers the problem. This patch: Declaration of early_pfn_to_nid() is scattered over per-arch include files, and it seems it's complicated to know when the declaration is used. I think it makes fix-for-memmap-init not easy. This patch moves all declaration to include/linux/mm.h After this, if !CONFIG_NODES_POPULATES_NODE_MAP && !CONFIG_HAVE_ARCH_EARLY_PFN_TO_NID -> Use static definition in include/linux/mm.h else if !CONFIG_HAVE_ARCH_EARLY_PFN_TO_NID -> Use generic definition in mm/page_alloc.c else -> per-arch back end function will be called.

2009-02-15net: new user space API for time stamping of incoming and outgoing packetsPatrick Ohly
User space can request hardware and/or software time stamping. Reporting of the result(s) via a new control message is enabled separately for each field in the message because some of the fields may require additional computation and thus cause overhead. User space can tell the different kinds of time stamps apart and choose what suits its needs. When a TX timestamp operation is requested, the TX skb will be cloned and the clone will be time stamped (in hardware or software) and added to the socket error queue of the skb, if the skb has a socket associated with it. The actual TX timestamp will reach userspace as a RX timestamp on the cloned packet. If timestamping is requested and no timestamping is done in the device driver (potentially this may use hardware timestamping), it will be done in software after the device's start_hard_xmit routine.

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>
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: 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: 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>
