drm/amdgpu: Add init level for post reset reinit2024-11-20T15:03:05+00:00Lijo Lazarlijo.lazar@amd.com2024-11-15T05:38:02+00:00urn:sha1:a86e0c0e94373aebc39c2efedaefc408f6a49fe3
When device needs to be reset before initialization, it's not required
for all IPs to be initialized before a reset. In such cases, it needs to
identify whether the IP/feature is initialized for the first time or
whether it's reinitialized after a reset.
Add RESET_RECOVERY init level to identify post reset reinitialization
phase. This only provides a device level identification, IP/features may
choose to track their state independently also.

drm/amdgpu: Save VCN shared memory with init reset2024-10-22T21:51:19+00:00Lijo Lazarlijo.lazar@amd.com2024-10-15T03:13:45+00:00urn:sha1:591aec150a984edcad99553ad9913abbfb8ab747
VCN shared memory is in framebuffer and there are some flags initialized
during sw_init. Ideally, such programming should be during hw_init.
Make sure the flags are saved during reset on initialization since that
reset will affect frame buffer region. For clarity, separate it out to
another function.

Before making a function call to suspend, validate
the function pointer like we do in sw_init.
Use the helper function amdgpu_ip_block_suspend where
same checks and calls are repeated.

In some cases, device needs to be reset before first use. Add handlers
for doing device reset during driver init sequence.

amdgpu_job_ring may return NULL, which causes kernel NULL
pointer error, using another way to print ring name instead
of ring->name.
