108 menu "Supported host OS features"
111 config ALIGNED_PG_ALLOC
112 bool "Host support for aligned page allocations"

116 if you want Palacios to run with large page table pages.
119 int "Maximum number of cpus"
123 Specifies the maximum number of hardware CPUs supported by the OS
124 For uniprocessor environments, set this to 1
128 source "palacios/src/interfaces/Kconfig"
129 source "palacios/src/extensions/Kconfig"
132 bool "Enable VMM telemetry support"
135 Enable the telemetry framework in Palacios
137 This is a framwork that allows components of palacios to record
138 information that is periodically reported to the log output.
139 Telemetry is automatically collected for vmexits. Subsystem telemetry
140 is configured separately
143 config SHADOW_PAGING_TELEMETRY
144 bool "Enable Shadow Paging Telemetry"
148 Enable telemetry information for shadow paging
153 bool "Enable Experimental options"
156 This allows the selection of experimental features. This includes incomplete or unreviewed code.
157 Only enable this feature if you are working on the features in question.
158 IMPORTANT: Non-experimental code MUST NOT use, require, or rely on experimental features.
159 Any code that violates this will be immediately deleted without warning.
161 The purpose of this option is to allow features under development to be committed to the mainline
162 to more easily track changes and provide access to multiple developers
165 bool "Enable Checkpointing"
166 depends on EXPERIMENTAL && KEYED_STREAMS
169 Temporary option to enable experimental checkpoint code

217 bool "Enable Time virtualization"
220 Enables the timer virtualization extensions
222 config TIME_HIDE_VM_COST
223 bool "Hide VMM Run Cost"
225 depends on VIRTUALIZE_TIME
227 Offset guest time from host time sufficiently to hide the cost of
228 running in the virtual machine. This can aid the consistency of
229 time between multiple timers, but can cause the guest to run
230 a good bit slower than the host in VM-intensive parts of the code.
232 config TIME_VIRTUALIZE_TSC
233 bool "Fully virtualize guest TSC"
235 depends on VIRTUALIZE_TIME
237 Virtualize the processor time stamp counter in the guest,
238 generally increasing consistency between various time sources
239 but also potentially making guest time run slower than real time.
