Currently the KVM code has to parse the firmware table to get the necessary information to setup the virtual timer and virtual GIC. However the parsing of those tables are already done in the GIC and arch timer drivers. This patch series introduces different helpers to retrieve the information from different drivers avoiding to duplicate the parsing code. Note there is patch series ([1] and [2]) adding support of KVM on ACPI, although the approach chosen is completely different. The code to parse the firmware tables are duplicated which I think make more complex to support new firmware tables.
