* oprofile: don't pass around redundant, easily derived argumentsJan Beulich2012-03-081-5/+3
| | | | | | | | | | | Passing both a struct vcpu pointer and the corresponding struct domain one is simply pointless, especially when intermediate functions just forward it without themselves making use of the already obtained value. Also constify a few function parameters. Signed-off-by: Jan Beulich <jbeulich@suse.com> Acked-by: Keir Fraser <keir@xen.org>
* xenoprof: Use uint64_t explicitly for internal callsGeorge Dunlap2012-01-261-2/+2
| | | | | | | | | | | | | A recent changeset to make XENOPROF_ESCAPE_CODE consistent across 32- and 64-bit builds caused a build failure, because values were passed through functions as "unsigned long". Replace these with uint64_t explicitly. Also remove redundant function prototype from perfmon.c, now that it's in a header file.

* force inclusion of xen/config.h through compiler optionJan Beulich2012-01-131-1/+0
| | | | | | | | | | | | | As we expect all source files to include the header as the first thing anyway, stop doing this by repeating the inclusion in each and every source file (and in many headers), but rather enforce this uniformly through the compiler command line. As a first cleanup step, remove the explicit inclusion from all common headers. Further cleanup can be done incrementally.

* x86_64: allow more vCPU-s per guestKeir Fraser2009-06-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Since the shared info layout is fixed, guests are required to use VCPUOP_register_vcpu_info prior to booting any vCPU beyond the traditional limit of 32. MAX_VIRT_CPUS, being an implemetation detail of the hypervisor, is no longer being exposed in the public headers. The tools changes are clearly incomplete (and done only so things would build again), and the current state of the tools (using scalar variables all over the place to represent vCPU bitmaps) very likely doesn't permit booting DomU-s with more than the traditional number of vCPU-s. Testing of the extended functionality was done with Dom0 (96 vCPU-s, as well as 128 vCPU-s out of which the kernel elected - by way of a simple kernel side patch - to use only some, resulting in a sparse bitmap). ia64 changes only to make things build, and build-tested only (and the tools part only as far as the build would go without encountering unrelated problems in the blktap code).
