[AMD Public Use]
Hi @Sheng, Wenhui,
Regarding the following corner cases that need to differentiate legacy mode 1
and new mode 1
1). Emergency start
Create a new function in amdgpu_ras.c, called amdgpu_ras_emergency_start, where
only execute the emergency start for the following configuration
Vega20 with PMFW version < 0x284300
2). the use_baco logic in amdgpu_device_gpu_recovery The remaining (in_ras_intr
&& !use_baco) are all serving for the emergency start case. we use
in_emergency_start or other proper name to replace use_baco
3). the use_baco logic in amdgpu_device_suspend_display_audio
It's safe to unified legacy mode 1 and new mode 1 to AMD_RESET_METHOD_MODE1.
The same behavior from driver perspective
4). Issue PP_MP1_STATE_SHUTDOWN (i.e. PrepareMp1ForShutdown) in suspend Same as
3). PrepareMp1ForShutdown is require for the new mode 1 reset as well. Please
try it
Regards,
Hawking

Hi @Zhang, Hawking
I tried to hide mp0/mp1 mode1 reset under AMD_RESET_METHOD_MODE1, while it
seems that we need to tackle the difference in function
amdgpu_device_gpu_recover, like following change in 3rd patch:

That's the reason I add new AMD_RESET_METHOD_PSP_MODE1.

Hi @Sheng, Wenhui,
I'm thinking of hiding the MP0/MP1 mode 1 reset under AMD_RESET_METHOD_MODE1.
the callback function reset is per ASIC function, where nv_asic_reset and
soc15_aisc_reset serve for NV series and pre-NV series respectively.
The new mode 1 reset will be used starting from sienna_cichlid. It should be
quite strait forward for us to either initialize a flag like
is_smu_support_mode1 during sw_init or even check the asic_type in
nv_asic_mode1_reset to decide whether we use psp_gpu_reset or smu_gpu_reset.etc.
That's saying, we don't need to change the reset_method interface, where we
decide whether we go to BACO/mode reset/pci config space reset.etc. We just
differentiate the approach (i.e. psp or smu) in nv_asic_mode1_reset.
Thoughts?
Regards,
Hawking

AMD_RESET_METHOD_MODE1 will be used by SMU
mode1 reset for sienna cichlid, so add
AMD_RESET_METHOD_PSP_MODE1 for psp mode1 reset.
