2023-07-12drm/amdgpu/gfx10: move update_spm_vmid() out of rlc_init()Alex Deucher1-8/+16
rlc_init() is part of sw_init() so it should not touch hardware. Additionally, calling the rlc update_spm_vmid() callback directly invokes a gfx on/off cycle which could result in powergating being enabled before hw init is complete. Split update_spm_vmid() into an internal implementation for local use without gfxoff interaction and then the rlc callback which includes gfxoff handling.

This patch updates the 'regs2' interface for MMIO registers to add a new IOCTL command for a 'v2' state data that includes the XCC ID. This patch then updates amdgpu_gfx_select_se_sh() and amdgpu_gfx_select_me_pipe_q() (and the implementations in the gfx drivers) to support an additional parameter. This patch then creates a new debugfs interface "gprwave" which is a merge of shader GPR and wave status access. This new inteface uses an IOCTL to select banks as well as XCC identity.
