[Description] Refactor code and move fpo_in_use into stream_status to avoid unexpected changes to previous dc_state (i.e., current_state). Since stream pointers are shared between current and new dc_states, updating parameters of one stream will update the other as well which causes unexpected behaviors (i.e., checking that fpo_in_use isn't set in previous state and set in the new state is invalid). To avoid incorrect updates to current_state, move the fpo_in_use flag into dc_stream_status since stream_status is owned by dc and are not shared between different dc_states. Reviewed-by:

[Description] Today for MED update type we do not call update clocks. However, for FPO the assumption is that update clocks should be called to disable P-State switch before any HW programming since FPO in FW and driver are not synchronized. This causes an issue where on a MED update, an FPO P-State switch could be taking place, then driver forces P-State disallow in the below code and prevents FPO from completing the sequence. In this case we add a check to avoid re-programming (and thus re-setting) the P-State force register by only reprogramming if the pipe was not previously Subvp or FPO. The assumption is that the P-State force register should be programmed correctly the first time SubVP / FPO was enabled, so there's no need to update / reset it if the pipe config has never exited SubVP / FPO.

[Why] When an eDP with high clock states is going into s0i3, stream_count is 0. This causes DML to not update the clks to the lowest state and blocking us to enter s0i3 since eDP is out of vmin. [How] When stream_count is 0, set all the clocks to the lowest state. Reviewed-by:

A wavefront may deallocate its VGPRs at the end of a program while waiting for memory transactions to complete. If it subsequently receives a context save exception it will be unable to save, since this requires VGPRs. In this case the trap handler should terminate the wavefront.

This commit fixes a type mismatch in the amdgpu_gfx_kiq_init_ring function triggered by the snprintf function expecting unsigned char arguments due to the '%hhu' format specifier, but receiving int and u32 arguments. The issue occurred because the arguments xcc_id, ring->me, ring->pipe, and ring->queue were of type int and u32, not unsigned char. This led to a type mismatch when these arguments were passed to snprintf. To resolve this, the snprintf line was modified to cast these arguments to unsigned char. This ensures that the arguments are of the correct type for the '%hhu' format specifier and resolves the warning. Fixes the below: >> drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c:333:4: warning: format >> specifies type 'unsigned char' but the argument has type 'int' >> [-Wformat] xcc_id, ring->me, ring->pipe, ring->queue); ^~~~~~ >> drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c:333:12: warning: format >> specifies type 'unsigned char' but the argument has type 'u32' (aka >> 'unsigned int') [-Wformat] xcc_id, ring->me, ring->pipe, ring->queue); ^~~~~~~~ drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c:333:22: warning: format specifies type 'unsigned char' but the argument has type 'u32' (aka 'unsigned int') [-Wformat] xcc_id, ring->me, ring->pipe, ring->queue); ^~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c:333:34: warning: format specifies type 'unsigned char' but the argument has type 'u32' (aka 'unsigned int') [-Wformat] xcc_id, ring->me, ring->pipe, ring->queue); ^~~~~~~~~~~ 4 warnings generated.

Work for __counted_by on generic pointers in structures (not just flexible array members) has started landing in Clang 19 (current tip of tree). During the development of this feature, a restriction was added to __counted_by to prevent the flexible array member's element type from including a flexible array member itself such as: struct foo { int count; char buf[]; }; struct bar { int count; struct foo data[] __counted_by(count); }; because the size of data cannot be calculated with the standard array size formula: sizeof(struct foo) * count This restriction was downgraded to a warning but due to CONFIG_WERROR, it can still break the build. The application of __counted_by on the states member of 'struct _StateArray' triggers this restriction, resulting in: drivers/gpu/drm/radeon/pptable.h:442:5: error: 'counted_by' should not be applied to an array with element of unknown size because 'ATOM_PPLIB_STATE_V2' (aka 'struct _ATOM_PPLIB_STATE_V2') is a struct type with a flexible array member. This will be an error in a future compiler version [-Werror,-Wbounds-safety-counted-by-elt-type-unknown-size] 442 | ATOM_PPLIB_STATE_V2 states[] __counted_by(ucNumEntries); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 error generated. Remove this use of __counted_by to fix the warning/error. However, rather than remove it altogether, leave it commented, as it may be possible to support this in future compiler releases.

The graphics_object_id structure is meant to fit into 32 bits, as it's passed by value in and out of functions.
