[RESEND v3 0/5] drm/amdgpu: Add new reset option and rework coredump

From: André Almeida

Hi,

The goal of this patchset is to improve debugging device resets on amdgpu.

The first patch creates a new module parameter to disable soft recoveries,
ensuring every recovery go through the full device reset, making easier to
generate resets from userspace tools like [0] and [1]. This is important to
validate how the stack behaves on resets, from end-to-end.

The last patches are a rework to alloc devcoredump dynamically and to move it to
a better source file.

I have dropped the patches that add more information to devcoredump for now,
until I figure out a better way to do so, like storing the IB address in the
fence.

Thanks,
André
