* trace: rename trace_hypercall() to __trace_hypercall_entry()David Vrabel2012-10-091-1/+1
| | | | | | | | Tracing functions that don't check tb_init_done are (by convention) prefixed with __. Signed-off-by: David Vrabel <david.vrabel@citrix.com> Committed-by: Keir Fraser <keir@xen.org>
* trace: trace hypercalls inside a multicallDavid Vrabel2012-10-031-1/+1
| | | | | | | | | | Add a trace record for every hypercall inside a multicall. These use a new event ID (with a different sub-class ) so they may be filtered out if only the calls into hypervisor are of interest.

* trace: improve usefulness of hypercall trace recordDavid Vrabel2012-10-031-20/+15
| | | | | | | | | | | | | | | | | | 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.

* xentrace: fix tracing for 64bit guestsKeir Fraser2008-06-091-8/+8
| | | | | | | | | | | | | | | | | | | | Xen tracing some times ago used to put values of type 'long' into the trace buffer. This has changed to uint32_t. Some trace points log virtual addresses, which get cropped to 32bit in this case. There were some inline functions to handle at least PF_XEN and VMEXIT, which caused a lot of code duplication. The attached patch fixes several issues: 1. fix and extend tools/xentrace/formats 2. Fix xentrace_format to handle up to 7 parameters 3. create convenience macros to properly log long values 4. remove the inline functions in hvm/trace.h and replace them by macros 5. Change the CPUID trace to work correctly 6. group HVM trace points enable mechanism I used a similar approach as in PV tracing with bit 8 indicating 64bit pointers.
