    DM: gvt: Identical mapping for GPU DSM refine to support EHL/TGL

    Windows graphic driver obtains DSM address from in-BAR mmio register
    which has passthroughed. Not like the other platforms obtained from
    pci configure space register which has virtualized. GPU GuC must use
    WOPCM in DSM, besides, Windows OS wants to manage DSM also. These two
    reason force acrn has to keep identical mapping to avoid trap mmio
    BAR to do the emulation.

I've tried the --windows parameter now, and it looks like I'm going to install. So without the --windows parameter, the Windows operating system cannot be installed.

[ionutnechita]

Hi @gvancuts,

In documentation page for "--windows" parameter. https://projectacrn.github.io/latest/user-guides/acrn-dm-parameters.html?highlight=windows

--windows This option is used to run Windows User VMs. It supports Oracle virtio-blk, virtio-net and virtio-input devices for Windows guests with secure boot.

usage:

--windows

A note may be mentioned to say that this parameter is important to detect the disk correctly. Without it included in acrn-dm, Windows OS cannot be installed or started.

[fuzhongl]

@ionutnechita Sorry for replying so later! As mentioned in following link, --windows is MUST parameter for WaaG. https://projectacrn.github.io/latest/tutorials/using_windows_as_uos.html

[gvancuts]

FYI, I also filed #5962 recently. It is also related to this.
