> Subject: [PATCH 3/3] drm/amd/ras: init reserved vram size before RAS core sw 
> init
>
> The RAS core derives the bad page threshold from
> con->reserved_pages_in_bytes when amdgpu_ras_mgr_sw_init() builds the
> EEPROM configuration. That field is still zero at this point, so the 
> threshold falls back
> to the 16MB default and ends up at 128 pages on ASICs that reserve 32MB.
>
> Set the reserved vram size before RAS core sw init so the threshold is 
> computed
> from the per-ASIC value.
