* KVM: ia64: Fix string literal continuation linesJoe Perches2010-03-011-2/+2
| | | | | | | | String constants that are continued on subsequent lines with \ are not good. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Avi Kivity <avi@redhat.com>
* KVM: Break dependency between vcpu index in vcpus array and vcpu_id.Gleb Natapov2009-09-101-1/+1
| | | | | | | | | Archs are free to use vcpu_id as they see fit. For x86 it is used as vcpu's apic id. New ioctl is added to configure boot vcpu id that was assumed to be 0 till now. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
* KVM: Introduce kvm_vcpu_is_bsp() function.Gleb Natapov2009-09-101-1/+1
| | | | | | | Use it instead of open code "vcpu_id zero is BSP" assumption. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>

* KVM: ia64: Create inline function kvm_get_itc() to centralize ITC reading.Jes Sorensen2009-06-101-2/+18
| | | | | | | | | | | Move all reading of special register 'AR_ITC' into two functions, one in the kernel and one in the VMM module. When running on SN2, base the result on the RTC rather the system ITC, as the ITC isn't synchronized.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the following warnings and related ones. Plus some cosmetics. arch/ia64/kernel/patch.c:112: warning: passing argument 1 of 'paravirt_fc' makes integer from pointer without a cast arch/ia64/kernel/patch.c:135: warning: passing argument 1 of 'paravirt_fc' makes integer from pointer without a cast arch/ia64/kernel/patch.c:166: warning: passing argument 1 of 'paravirt_fc' makes integer from pointer without a cast arch/ia64/kernel/patch.c:202: warning: passing argument 1 of 'paravirt_fc' makes integer from pointer without a cast arch/ia64/kernel/patch.c:220: warning: passing argument 1 of 'paravirt_fc' makes integer from pointer without a cast Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Tony Luck <tony.luck@intel.com>
* | KVM: ia64: dynamic nr online cpusJes Sorensen2009-03-241-1/+4
| | | | | | | | | | | | | | | | | | | | | | Account for number of online cpus and use that in loops iterating over the list of vpus instead of scanning the full array unconditionally. This patch is a building block to facilitate allowing to bump up the size of MAX_VCPUS significantly.

* KVM: ia64: Re-organize data sturure of guests' data areaXiantao Zhang2008-12-311-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
