179 is configured separately
182 config SHADOW_PAGING_TELEMETRY
183 bool "Enable Shadow Paging Telemetry"
187 Enable telemetry information for shadow paging
192 bool "Enable Experimental options"
195 This allows the selection of experimental features. This includes incomplete or unreviewed code.
196 Only enable this feature if you are working on the features in question.
197 IMPORTANT: Non-experimental code MUST NOT use, require, or rely on experimental features.
198 Any code that violates this will be immediately deleted without warning.
200 The purpose of this option is to allow features under development to be committed to the mainline
201 to more easily track changes and provide access to multiple developers
204 depends on EXPERIMENTAL

285 running in the virtual machine. This can aid the consistency of
286 time between multiple timers, but can cause the guest to run
287 a good bit slower than the host in VM-intensive parts of the code.
289 config TIME_VIRTUALIZE_TSC
290 bool "Fully virtualize guest TSC"
