H A D | virt.rst | 7cf3f8d2 Fri Apr 08 09:15:50 CDT 2022 Peter Maydell <peter.maydell@linaro.org> hw/arm/virt: Support TCG GICv4
Add support for the TCG GICv4 to the virt board. For the board, the GICv4 is very similar to the GICv3, with the only difference being the size of the redistributor frame. The changes here are thus: * calculating virt_redist_capacity correctly for GICv4 * changing various places which were "if GICv3" to be "if not GICv2" * the commandline option handling
Note that using GICv4 reduces the maximum possible number of CPUs on the virt board from 512 to 317, because we can now only fit half as many redistributors into the redistributor regions we have defined.
