[why] On some modes SMU will be in infinite loop state at boot, this is because driver assumes p_state_support is false, but this is the opposite of the assumed boot state by SMU. we optimize away notifying SMU about no pstate, and so they will get stuck [how] when we init clk manager, init pstate to true, so it matches driver load assumption Signed-off-by:

Since we are using the signed FW now, and also using PSP firmware loading, but it's still potential to break driver when loading FW directly instead of PSP, so we should add offset. Signed-off-by:

The GDS and GWS blocks default to allowing all VMIDs to access all entries. Graphics VMIDs can handle setting these limits when the driver launches work. However, compute workloads under HWS control don't go through the kernel driver. Instead, HWS firmware should set these limits when a process is put into a VMID slot. Disable access to these devices by default by turning off all mask bits (for OA) and setting BASE=SIZE=0 (for GDS and GWS) for all compute VMIDs. If a process wants to use these resources, they can request this from the HWS firmware (when such capabilities are enabled). HWS will then handle setting the base and limit for the process when it is assigned to a VMID. This will also prevent user kernels from getting 'stuck' in GWS by accident if they write GWS-using code but HWS firmware is not set up to handle GWS reset. Until HWS is enabled to handle GWS properly, all GWS accesses will MEM_VIOL fault the kernel. v2: Move initialization outside of SRBM mutex Signed-off-by:

[WHY] dc sw clock implementation of navi10 and raven are not exact the same. dcccg, dchub reference clock initialization is done after dc calls vbios dispcontroller_init table. for raven family, before dispcontroller_init is called by dc, the ref clk values are referred by sw clock implementation and program asic register using wrong values. this causes dchub pstate error. This need provide valid ref clk values. for navi10, since dispcontroller_init is not called, dchubbub_global_timer_enable = 0, hubbub2_get_dchub_ref_freq will hit aeert. this need remove hubbub2_get_dchub_ref_freq from this location and move to dcn20_init_hw. [HOW] for all asic, initialize dccg, dchub ref clk with data from vbios firmware table by default. for raven asic family, use these data from vbios, for asic which support sw dccg component, like navi10, read ref clk by sw dccg functions and update the ref clk.

If we shut down a process without having destroyed its GWS-using queues, it is possible that GWS BO will still be in the process BO list during the gpuvm destruction. This list should be empty at that time, so we should remove the GWS allocation at the process uninit point if it is still around. Signed-off-by:

Under memory pressure, buffer moves between RAM to VRAM can fail when there is no GTT space available. In those cases amdgpu_bo_move falls back to ttm_bo_move_memcpy, which seems to succeed, although it doesn't really support non-contiguous or invisible VRAM. This manifests as VM faults with corrupted page table entries in KFD eviction stress tests. Print some helpful messages when lack of GTT space is causing buffer moves to fail. Check that source and destination memory regions are supported by ttm_bo_move_memcpy before taking that fallback. Signed-off-by:

Prefetch mode 0 is not supported and can lead to hangs with certain very specific code patterns. Set a sound prefetch mode for all VMIDs rather than forcing all shaders to set the prefetch mode at the beginning. Reduce code duplication a bit while we're at it. Note that the 64-bit address mode enum and the retry all enum are both 0, so the only functional change is in the INITIAL_INST_PREFETCH field. Signed-off-by:

The simple_strtol() function is deprecated. kstrto[l,u32]() is the correct replacement as it can properly handle overflows. This patch replaces the deprecated simple_strtol() use introduced recently. As clk is of type uint32_t, we are safe to use kstrtou32(). It is also safe to return zero on string parsing error, similar to the case of returning zero if buf is empty in parse_clk().
