[PATCH 0/9] Enable new L1 security for Vega10 SR-IOV

[Trigger Huang]

To support new Vega10 SR-IOV L1 security, KMD need some modifications
        1: Due to the new features supported in FW(PSP, RLC, etc),
           for register access during initialization, we have more
           modes:
                1), request PSP to program
                2), request RLC to program
                3), request SR-IOV host driver to program and skip
                    programming them in amdgpu
                4), Legacy MMIO access
           We will try to read the firmware version to see which mode
           is support

        2: If PSP FW support to program some registers, such as IH,
           we need:
                1), initialize PSP before IH
                2), send the specific command to PSP

        3: Support VMR ring. VMR ring, compared with physical platform
           TMR ring, the program sequence are nearly the same,  but we
           will use another register set, mmMP0_SMN_C2PMSG_101/102/103
           to communicate with PSP

        4: Skip programming some registers in guest KMD
           As some registers are processed by new L1 security, amdgpu
           on VF will fail to program them, and don’t worry, these
           registers will be programmed  on the SR-IOV host driver
           side.

        5: Call RLC to program some registers in instead of MMIO
           With new L1 policy, some registers can’t be programmed in
           SR-IOV VF amdgpu with MMIO. Fortunately, new RLC firmware
           will support to program them with specific program sequence,
           which are described in the patch commit message

Trigger Huang (9):
  drm/amdgpu: init vega10 SR-IOV reg access mode
  drm/amdgpu: initialize PSP before IH under SR-IOV
  drm/amdgpu: Add new PSP cmd GFX_CMD_ID_PROG_REG
  drm/amdgpu: implement PSP cmd GFX_CMD_ID_PROG_REG
  drm/amdgpu: call psp to progrm ih cntl in SR-IOV
  drm/amdgpu: Support PSP VMR ring for Vega10 VF
  drm/amdgpu: Skip setting some regs under Vega10 VF
  drm/amdgpu: add basic func for RLC program reg
  drm/amdgpu: RLC to program regs for Vega10 SR-IOV
