* Sanitise the trace-buffer hypervisor<->user interface.kaf24@firebug.cl.cam.ac.uk2005-10-311-6/+4
| | | | | Signed-off-by: Keir Fraser <keir@xensource.com>
* This is a set of changes which allow the tracebuffer functionality tokaf24@firebug.cl.cam.ac.uk2005-10-303-1/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | be enabled and disabled dynamically while the system is running. The existing DOM0_TBUFCONTROL hypercall is used, and three new operations have been added: enable, disable, and set_size. This is to address concerns that use of the trace buffers impacts system performance. The initial value of opt_tbuf_size is set to zero, so that trace buffers remain disabled by default. They can be enabled as they used to be, by adding tbuf_size= to the xen command line at boot time. They can also be turned on and off any time when the system is running. The size of the trace buffer allocation can also be changed dynamically while the system is running. The trace buffers may be completely deallocated by setting the size to zero. No change in buffer size can be done while tracing is enabled; Other Changes made: - Update the constants in tools/xentrace/formats to match those in public/trace.h - libxc functions for enable/disable, get/set size Still left to do: - remove all ifdef's for trace buffers and the 'trace' build option - xm command to do enable/disable trace buffers and get/set size Signed-off-by: Rob Gardner <rob.gardner@hp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) enable ACPI in VMXAssist by default. 2) do nothing when emulating wbinvd instruction in VMXAssist. 3) use MACRO in cpu number setting/getting code. 4) remove useless parameter flags from xc_vmx_build. 5) remove usage of dsi.v_start in xc_vmx_build when not handling vmxloader elf. 6) unmap shared_page_va when destroy VMX domain. 7) change virtual_platform_def to vmx_platform. 8) remove useless code in vmx_setup_platform. 9) change parameter of vmx_setup_platform from vcpu to domain. 10) in xen HV, vmx domain get domain processor number from the reserved E820 area. 11) in domain.c, don't define some functions when on i386 platform or no CONFIG_VMX. Also removed some ugly tailing space. Signed-off-by: Xin Li <xin.b.li@intel.com>
| * Take advantage of the new UUID (handle) stored for us in Xen to improve theemellor@leeni.uk.xensource.com2005-10-191-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | recreation semantics. Remove the unpause at the end of xc_linux_restore, and move it to XendDomainInfo. This is necessary because xenstored now allocates the domain path when the domain is introduced, which means that the new domain cannot start running until that introduce is performed and the new devices configured. Give restore a separate completion phase in which domain details are stored. This is required because the domain path is no longer available until after the introduceDomain call. TODO: Split the domain introduction into two so that the domain path is available earlier. At the moment, the domain <-> store channel details are passed in to xenstored when the domain is introduced, but in the case of restore it is necessary to wait until the restore is completed before the channel MFN is available. Change the interface between XendDomainInfo and XendCheckpoint/image to not have hideous callbacks through setConsoleRef and setStoreRef. Instead, image.createImage explicitly returns those values, and XendCheckpoint passes them through to completeRestore. Move the purging of the domain path corresponding to a new domain from Xend to xenstored, since xenstored is now in charge of this path. With the domain path creation moved to xenstored, Xend cannot remove the path, because watches may have fired on it already. Fix the printf statement in xenstored in verbose mode that details the messages being written. This statement was printing the buffer using %s, but this buffer has an explicit length field, so we were seeing garbage after the correct details. Signed-off-by: Ewan Mellor <ewan@xensource.com>

Thi sensures appropriate alignment for architectures that require it, and also allows us to naturally support up to 4096 event channels per 64-bit guest. Moved 'n_vcpu' field from shared_info to start_info. Really it ought to disappear altogether as the info can be derived from xenstore. Fix a weird bug in XendDomainInfo where 'vcpus' information for a domain defaults to floating point value 1.0 rather than integer 1. This looks like a Python bug to me, but in any case it is 'fixed' by explicitly converting the default value to an integer. Signed-off-by: Keir Fraser <keir@xensource.com>
| * | Have xenstored initialise its connections, meaning that xend can be out ofemellor@leeni.uk.xensource.com2005-10-172-17/+3
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that loop completely -- the xc_init_store, initDomainStore calls can all go. Have xenstored understand where the local domain information goes. Xend no longer has to generate a path and pass it to xenstored through xs_introduce_domain -- we just allow xenstored to generate the path, and then call GetDomainPath later. There is still some work required to tidy this up. Change the uuid module to generate uuids as lists of bytes, not in the stringified form. Added a unit test for that module. Change the semantics of Xend restart, relying on these changes to the xenstored semantics and earlier changes to add an opaque handle to the hypervisor's domain-specific data block. The semantics are now clearer, as Xend can validate whether the details in the store match the current live domain. Added a usage statement to xenstored. Some of this code is by Steven Hand.
