Guest may write a MSI-X capability register with only RW bits setting on. This works well on native since the hardware will make sure RO register bits could not over-write. However, the software needs more efforts to achieve this. This patch does this by defining a RW permission mapping base on bits. When a guest tries to write a MSI-X Capability register, only modify the RW bits on vCFG space. Tracked-On: #4550 Signed-off-by: Li Fei1 <fei1.li@intel.com> |
