The original patch introduced additional latency during boot time
because it triggers a driver reload to avoid a CP hang when the driver
is reloaded multiple times. This has been addressed with a more generic
solution that triggers the GPU reset only during the unload phase,
avoiding extra latency during boot time. For this reason, this commit
reverts the original change.
This reverts commit 72a98763b4.
This patch should only be applied if commit:

When the driver initializes the GPU, the PSP validates all the firmware
loaded, and after that, it is not possible to load any other firmware
unless the device is reset. What is happening in the load/unload
situation is that PSP halts the GC engine because it suspects that
something is amiss. To address this issue, this commit ensures that the
GPU is reset (mode 2 reset) in the unload sequence.

The MMIO_REMAP BO is a special 4K IO page that does not have a ttm_tt
behind it. However, amdgpu_ttm_tt_pde_flags() was treating it like
normal TT/doorbell/preempt memory and unconditionally accessed
ttm->caching. For the MMIO_REMAP BO, ttm is NULL, so this leads to a
NULL pointer dereference when computing PDE flags.
Fix this by checking that ttm is non-NULL before reading ttm->caching.
This prevents the crash for MMIO_REMAP and also makes the code more
defensive if other BOs ever come through without a ttm_tt.

[Why]
Some monitors perform rapid “autoscan” HPD re‑assertions right after a
disconnect or powersaving mode enablement. These appear as a quick
disconnect→reconnect with an identical EDID. Since Linux has no HDMI
hotplug detection (HPD) filter, these quick reconnects are seen as hotplug
events, which can unintentionally wake a system with DPMS off.
An example: https://gitlab.freedesktop.org/drm/amd/-/issues/2876
Such 'fake reconnects' are considered when the interval between a
disconnect and a connect is within 1500ms (experimentally chosen using
several monitors), and the two connections have the same EDID.
[How]
Implement a time-based debounce mechanism:
1. On HDMI disconnect detection, instead of immediately processing the
HPD event, save the current sink and schedule delayed work (default 1500ms)
2. If another HDMI disconnect HPD event arrives during the debounce period,
it reschedules the pending work, ensuring only the final state is processed.
3. When the debounce timer expires, re-detect the display and compare the
new sink with the cached one using EDID comparison.
4. If sinks match (same EDID), this was a spontaneous HPD toggle:
- Update connector state internally
- Skip hotplug event to prevent desktop rearrangement
If sinks differ, this was a real display change:
- Process normally with the hotplug event
The debounce delay is configurable via module parameter
'hdmi_hpd_debounce_delay_ms'.

Now that the DC analog connector support and VCE1 support landed,
amdgpu is at feature parity with the old radeon driver
on SI dGPUs.
Enabling the amdgpu driver by default for SI dGPUs has the
following benefits:
- More stable OpenGL support through RadeonSI
- Vulkan support through RADV
- Improved performance
- Better display features through DC
Users who want to keep using the old driver can do so using:
amdgpu.si_support=0 radeon.si_support=1
v2:
- Update documentation in Kconfig file

When we run out of VMIDs we need to wait for some to become available.
Previously we were using a dma_fence_array for that, but this means that
we have to allocate memory.
Instead just wait for the first not signaled fence from the least recently
used VMID to signal. That is not as efficient since we end up in this
function multiple times again, but allocating memory can easily fail or
deadlock if we have to wait for memory to become available.
v2: remove now unused VM manager fields
v3: fix dma_fence reference

The amd-smi tool relies on extended peer link information to report xgmi
link metrics. The necessary xgmi ta command, GET_EXTEND_PEER_LINKS, has
been enabled in the host driver and this change is necessary for the
guest to make use of it. To handle the case where the host driver does
not have the latest xgmi ta, the guest driver checks for guest support
through a pf2vf feature flag before invoking psp.

amdgpu_xgmi_fill_topology_info and psp_xgmi_reflect_topology_info
perform the same logic of copying topology info of one node to every
other node in the hive. Instead of having two functions that purport to
do the same thing, this refactoring moves the logic of the fill function
to the reflect function and adds reflecting port number info as well for
complete functionality.

The amdgpu driver has been working well on CIK dGPUs for years.
Now that the DC analog connector support landed, these GPUs
are at feature parity with the old radeon driver.
Additionally, amdgpu yields extra performance, supports Vulkan

robust power management.

Move the determination into a separate function.
Change amdgpu.si_support and amdgpu.cik_support so that their
default value is -1 (default).
This prepares the code for changing the default driver based
on the chip.
Also adjust the module param documentation.
