| Thread-topic: | [PATCH 1/2][HVM] Dynamic MP tables based upon VCPU count |
[HVM][Firmware] Make the creation of MP tables more dynamic Currently the ROMBIOS includes static MP tables for only four configurations: 1-way, 2-way, 4-way, and 8-way. This patch makes the creation of MP tables more dynamic by creating them from within HVMLOADER based upon the VCPU number provided by the HVM information table. Note: Some of the information included used to create the MP tables is still hard coded and based upon values used in the original ROMBIOS MP tables. Data such as the CPU family/model/stepping information should probably be made to match the information provided to the guest when executing a CPUID. Signed-off-by: Travis Betak <travis.betak@xxxxxxx>
