2024-07-26pnv/xive2: Configure Virtualization Structure Tables through the PCFrederic Barrat
Both the virtualization layer (VC) and presentation layer (PC) need to be configured to access the VSTs. Since the information is redundant, the xive model combines both into one set of tables and only the definitions going through the VC are kept. The definitions through the PC are ignored. That works well as long as firmware calls the VC for all the tables. For the NVG and NVC tables, it can make sense to only configure them with the PC, since they are only used by the presenter. So this patch allows firmware to configure the VST tables through the PC as well. The definitions are still shared, since the VST tables can be set through both the VC and/or PC, they are dynamically re-mapped in memory by first deleting the memory subregion.
