* libxc: introduce xc_domain_get_guest_width()Dario Faggioli2013-09-131-6/+3
| | | | | | | | | | | | | | As a wrapper to XEN_DOMCTL_get_address_size, and use it wherever the call was being issued directly via do_domctl(), saving quite some line of code. Actually, the function returns the guest width in bytes, rather than directly what XEN_DOMCTL_get_address_size provides (which is a number of bits), since that is what it is useful almost everywhere.

* trace: improve usefulness of hypercall trace recordDavid Vrabel2012-10-032-0/+7
| | | | | | | | | | | | | | | | | | Trace hypercalls using a more useful trace record format. The EIP field is removed (it was always somewhere in the hypercall page) and include selected hypercall arguments (e.g., the number of calls in a multicall, and the number of PTE updates in an mmu_update etc.). 12 bits in the first extra word are used to indicate which arguments are present in the record and what size they are (32 or 64-bit). This is an incompatible record format so a new event ID is used so tools can distinguish between the two formats.

* trace: allow for different sub-classes of TRC_PV_* tracepointsDavid Vrabel2012-10-031-22/+22
| | | | | | | | | | | | | | | | | | We want to add additional sub-classes for TRC_PV tracepoints and to be able to only capture these new sub-classes. This cannot currently be done as the existing tracepoints all use a sub-class of 0xf. So, redefine the PV events to use a new sub-class. All the current tracepoints are tracing entry points to the hypervisor so the sub-class is named TRC_PV_ENTRY. This change does not affect xenalyze as that only looks at the main class and the event number and does not use the sub-class field.

* tools/build: Introduce {PREPEND,APPEND}_{LIB,INCLUDES}Roger Pau Monne2011-11-141-3/+3
| | | | | | | | | | | | | | | | | | | | | | | Create two new variables called APPEND_ and PREPEND_ to add compile flags at the beginning or at the end of the search path. Added a new semantic for user defined compile flags, here is the list of possible options: PREPEND_LIB: add libraries to the search path before xen (before xen installation folders). PREPEND_INCLUDES: add headers to the search path before xen (before xen installation folders). APPEND_LIB: add libraries to the search path at the end (after all xen installation folders have been added). APPEND_INCLUDES: add libraries to the search path at the end (after all xen installation folders have been added). EXTRA_INCLUDES and EXTRA_LIB can still be used, and they will have the same effect as PREPEND_INCLUDES and PREPEND_LIB.

| | | | | | | | | | | | | | | | | | | | 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>

* xentrace: Per-cpu xentrace buffersKeir Fraser2010-01-201-73/+60
| | | | | | | | | | | | | | | | In the current xentrace configuration, xentrace buffers are all allocated in a single contiguous chunk, and then divided among logical cpus, one buffer per cpu. The size of an allocatable chunk is fairly limited, in my experience about 128 pages (512KiB). As the number of logical cores increase, this means a much smaller maximum per-cpu trace buffer per cpu; on my dual-socket quad-core nehalem box with hyperthreading (16 logical cpus), that comes to 8 pages per logical cpu. This patch addresses this issue by allocating per-cpu buffers separately. Signed-off-by: George Dunlap <dunlapg@umich.edu>
