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. (v2) Fix missing xcc_id in wave_ind function (v3) Fix pm runtime calls and mutex locking (v4) Fix bad label Signed-off-by: Tom St Denis <tom.stdenis@amd.com> Reviewed-by: Harish Kasiviswanathan <Harish.Kasiviswanathan@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
