drm/amd/amdgpu: Update debugfs for XCC support (v3)

2023-06-09T13:48:22+00:00

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 Reviewed-by: Harish Kasiviswanathan Signed-off-by: Alex Deucher

drm/amd/amdgpu: New debugfs interface for MMIO registers (v5)

2021-09-01T20:55:11+00:00

This new debugfs interface uses an IOCTL interface in order to pass along state information like SRBM and GRBM bank switching. This new interface also allows a full 32-bit MMIO address range which the previous didn't. With this new design we have room to grow the flexibility of the file as need be. (v2): Move read/write to .read/.write, fix style, add comment for IOCTL data structure (v3): C style comments (v4): use u32 in struct and remove offset variable (v5): Drop flag clearing in op function, use 0xFFFFFFFF for broadcast instead of 0x3FF, use mutex for op/ioctl.
