* libxl,libxc: introduce libxl_get_numainfo()Dario Faggioli2012-07-061-0/+14
| | | | | | | | | | | | | Make some NUMA node information available to the toolstack. Achieve this by means of xc_numainfo(), which exposes memory size and amount of free memory of each node, as well as the relative distances of each node to all the others. For properly exposing distances we need the IDL to support arrays.

Also the dirty_bitmap buffer is output only and therefore only needs bouncing in one direction.

* tools: change cpumaps to uint8_tJuergen Gross2010-11-031-0/+15
| | | | | | | | | | | | | | | | | | | | Cpumap types in tools (libxc and libxl) are changed to be based on bytes like in the interface to the hypervisor. To make handling easier the size of used cpumaps is always based on the number of physical cpus supported by the hypervisor. This eliminates the need to keep track of the cpumap size in external interfaces. In libxl a macro for cycling through a cpumap is added (libxl_for_each_cpu). Interfaces changed: libxl_set_vcpuaffinity() libxl_cpumap_alloc() xc_vcpu_setaffinity() xc_vcpu_getaffinity() xc_cpupool_freeinfo() Signed-off-by: Juergen Gross <juergen.gross@ts.fujitsu.com> Acked-by: Ian Campbell <ian.campbell@citrix.com> Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* libxc: remove \n from strings passed to PERRORKeir Fraser2010-05-281-1/+1

* libxc: eliminate static variables, use xentoollog; API changeKeir Fraser2010-05-281-36/+36
| | | | | | | | | | | | | | | | | | | | This patch eliminate the global variables in libxenctrl (used for logging and error reporting). Instead the information which was in the global variables is now in a new xc_interface* opaque structure, which xc_interface open returns instead of the raw file descriptor; furthermore, logging is done via xentoollog. There are three new parameters to xc_interface_open to control the logging, but existing callers can just pass "0" for all three to get the old behaviour. All libxc callers have been adjusted accordingly. Also update QEMU_TAG for corresponding qemu change. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

| | | | | | | | | | 'xm info' command now also gives the cpu topology & host numa information. This will be later used to build guest numa support.

* libxc: mmapbatch-v2 adjustmentsKeir Fraser2010-01-221-3/+4
| | | | | | | | | | | | | | | Just like the kernel, the fallback implementation of xc_map_foreign_bulk() should clear the error indication array upon success. Also, a few allocations were needlessly using calloc() instead of malloc(). Finally, in xc_domain_save() allocate the error indicator array once (along with the other arrays) instead of using realloc() (without error checking) in the loop body.

* libxc: New hcall_buf_{prep,release} pre-mlock interfaceKeir Fraser2010-01-221-25/+25
| | | | | | | | | | Allow certain performance-critical hypercall wrappers to register data buffers via a new interface which allows them to be 'bounced' into a pre-mlock'ed page-sized per-thread data area. This saves the cost of mlock/munlock on every such hypercall, which can be very expensive on modern kernels. Signed-off-by: Keir Fraser <keir.fraser@citrix.com>
* libxc: use new (replacement) mmap-batch ioctlKeir Fraser2010-01-131-14/+55
| | | | | | | | | | | | | | | | | | | | Replace all calls to xc_map_foreign_batch() where the caller doesn't look at the passed in array to check for errors by calls to xc_map_foreign_pages(). Replace all remaining calls by such to the newly introduced xc_map_foreign_bulk(). As a sideband modification (needed while writing the patch to ensure they're unused) eliminate unused parameters to uncanonicalize_pagetable() and xc_map_foreign_batch_single(). Also unmap live_p2m_frame_list earlier in map_and_save_p2m_table(), reducing the peak amount of virtual address space required. All supported OSes other than Linux continue to use the old ioctl for the time being. Also change libxc's MAJOR to 4.0 to reflect the API change. Signed-off-by: Jan Beulich <jbeulich@novell.com>

| | | | | | | | | | This adds a new HVM op that enables tracking dirty bits of a range of video RAM.

Add INTSRC overrides in MPBIOS and ACPI tables so that PCI legacy IRQ routing always ends up at an IO-APIC input with level trigger.

| | | | | | | | | | | | | | This simplifies the IRQ logic significantly and avoids the bogus hvm_pic_assist() on domain resume path. There is more work to be done here. At least: 1. set-irq-level should really be set-interrupt-wire-level. Wire state needs to be distinguished from PIC (in particular, PIC IRR) state. 2.

| | | | | | | | | | | | | | | | | | | | | | 1. platform_op -- used by dom0 kernel to perform actions on the hardware platform (e.g., MTRR access, microcode update, platform quirks, ...) 2. domctl -- used by management tools to control a specified domain 3. sysctl -- used by management tools for system-wide actions Benefits include more sensible factoring of actions to hypercalls. Also allows tool compatibility to be tracked separately from the dom0 kernel. The assumption is that it will be easier to replace libxenctrl, libxenguest and Xen as a matched set if the dom0 kernel does not need to be replaced too (e.g., because that would require vendor revalidation). From here on we hope to maintain dom0 kernel compatibility. This promise is not extended to tool compatibility beyond the existing guarantee that compatibility will not be broken within a three-level stable release [3.0.2, 3.0.3, etc.].
