Currently, the emulation of pci msi/msix can be handled by hypervisor code. The logic in dm passthru driver can be simplified. This patch remaps msix table to usersapce in DM passthru driver. 1. The access to the msix table in passthru driver will be trapped, and emulated by hv code. 2. The access to the config space in passthru driver will be trapped, and emulated by hv code. So dm passthru driver no longer needs to keep the whole logic of handling msi/msix. No need to do msix table remapping in sos kernel. After the patch, the msix table ioremap code in vhm_dev.c can be removed. Tracked-On: #1782 Signed-off-by: Binbin Wu <binbin.wu@intel.com> Reviewed-by: Shuo A Liu <shuo.a.liu@intel.com>
