*	KVM: remove old KVMTRACE support code	Marcelo Tosatti	2009-09-10	1	-285/+0
\| \| \| \| \| \| \|	Return EOPNOTSUPP for KVM_TRACE_ENABLE/PAUSE/DISABLE ioctls. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
*	KVM: Prevent trace call into unloaded module text	Wu Fengguang	2008-12-31	1	-0/+1
\| \| \| \| \| \| \| \|	Add marker_synchronize_unregister() before module unloading. This prevents possible trace calls into unloaded module text. Signed-off-by: Wu Fengguang <wfg@linux.intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
*	KVM: kvmtrace: replace get_cycles with ktime_get v3	Christian Ehrhardt	2008-10-15	1	-9/+10
\| \| \| \| \| \| \| \| \| \| \| \| \|	The current kvmtrace code uses get_cycles() while the interpretation would be easier using using nanoseconds. ktime_get() should give at least the same accuracy as get_cycles on all architectures (even better on 32bit archs) but at a better unit (e.g. comparable between hosts with different frequencies.

*	KVM: kvmtrace: Remove use of bit fields in kvm trace structure	Christian Ehrhardt	2008-10-15	1	-8/+9
\| \| \| \| \| \| \| \| \| \| \|	This patch fixes kvmtrace use on big endian systems. When using bit fields the compiler will lay data out in the wrong order expected when laid down into a file. This fixes it by using one variable instead of using bit fields.

*	KVM: Support mixed endian machines	Tan, Li	2008-07-20	1	-6/+12
\| \| \| \| \| \| \| \| \| \| \| \|	Currently kvmtrace is not portable. This will prevent from copying a trace file from big-endian target to little-endian workstation for analysis. In the patch, kernel outputs metadata containing a magic number to trace log, and changes 64-bit words to be u64 instead of a pair of u32s.

*	KVM: Rename debugfs_dir to kvm_debugfs_dir	Hollis Blanchard	2008-04-27	1	-2/+2
\| \| \| \| \| \| \|	It's a globally exported symbol now. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
*	KVM: Add kvm trace userspace interface	Feng(Eric) Liu	2008-04-27	1	-0/+276
	This interface allows user a space application to read the trace of kvm related events through relayfs. Signed-off-by: Feng (Eric) Liu <eric.e.liu@intel.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
