To improve reliability of the system in the case of infrequent or
potentially recoverable hangs when the DMU times out.
[How]
Attempt to recover the ASIC when DMU hangs by triggering a crash
recovery callback for the DM to forward to the base driver.

[why & how]
VBIOS DMCUB FW can enable FEC for capable eDPs, but S/W DC state is
only updated for link0 when transitioning into OS with driver loaded.
This causes issues when the eDP is immediately hidden and DIG0 is
assigned to another link that does not support FEC. Driver will
attempt to disable FEC but FEC enablement occurs based on the link
state, which does not have fec_state updated since it is a different
link. Thus, FEC disablement on DIG0 will get skipped and cause no
light up.

In error scenarios (e.g., malformed commands), user queue fences may never
be signaled, causing processes to wait indefinitely. To address this while
preserving the requirement of infinite fence waits, implement an independent
timeout detection mechanism:
1. Initialize a hang detect work when creating a user queue (one-time setup)
2. Start the work with queue-type-specific timeout (gfx/compute/sdma) when
the last fence is created via amdgpu_userq_signal_ioctl (per-fence timing)
3. Trigger queue reset logic if the timer expires before the fence is signaled
v2: make timeout per queue type (adev->gfx_timeout vs adev->compute_timeout vs adev->sdma_timeout) to be consistent with kernel queues. (Alex)
v3: The timeout detection must be independent from the fence, e.g. you don't wait for a timeout on the fence
but rather have the timeout start as soon as the fence is initialized. (Christian)
v4: replace the timer with the `hang_detect_work` delayed work.

PCIe reads need to be done inside the time sandwich because PCIe
writes may get buffered in the PCIe fabric and posted to the device
after the _postts completes. Doing the PCIe read inside the time
sandwich guarantees that the write gets flushed before the _postts
timestamp is taken.

Commit 4da71a77fc3b ("ice: read internal temperature sensor") introduced
internal temperature sensor reading via HWMON. ice_hwmon_init() was added
to ice_init_feature() and ice_hwmon_exit() was added to ice_remove(). As a
result if devlink reload is used to reinit the device and then the driver
is removed, a call trace can occur.
BUG: unable to handle page fault for address: ffffffffc0fd4b5d
Call Trace:
string+0x48/0xe0
vsnprintf+0x1f9/0x650
sprintf+0x62/0x80
name_show+0x1f/0x30
dev_attr_show+0x19/0x60
The call trace repeats approximately every 10 minutes when system
monitoring tools (e.g., sadc) attempt to read the orphaned hwmon sysfs
attributes that reference freed module memory.
The sequence is:
1. Driver load, ice_hwmon_init() gets called from ice_init_feature()
2. Devlink reload down, flow does not call ice_remove()
3. Devlink reload up, ice_hwmon_init() gets called from
ice_init_feature() resulting in a second instance
4. Driver unload, ice_hwmon_exit() called from ice_remove() leaving the
first hwmon instance orphaned with dangling pointer
Fix this by moving ice_hwmon_exit() from ice_remove() to
ice_deinit_features() to ensure proper cleanup symmetry with
ice_hwmon_init().

Several ioctl functions have the ability to call ice_get_rxfh, however
all of these ioctl functions do not provide all of the expected
information in ethtool_rxfh_param. For example, ethtool_get_rxfh_indir does
not provide an rss_key. This previously caused ethtool_get_rxfh_indir to
always fail with -EINVAL.
This change draws inspiration from i40e_get_rss to handle this
situation, by only calling the appropriate rss helpers when the
necessary information has been provided via ethtool_rxfh_param.

Switch the driver to use scnprintf() to avoid warnings about potential
truncation of "phys" field which we can tolerate.

On MT8196/MT6991, per-sensor calibration data read from eFuses is
16-bit. When the LVTS controller operates in 16-bit mode, a fixed offset
must be added to MSR values during post-processing to obtain correct
temperature readings. Introduce a new msr_offset field in lvts_data,
program the respective register and apply the offset to the calibration
data read from eFuses.

MT8196/MT6991 uses ATP (Abnormal Temperature Prevention) mode to detect
abnormal temperature conditions, which involves reading temperature data
from a dedicated set of registers separate from the ones used for
immediate and filtered modes.
Add support for ATP mode and its relative registers to ensure accurate
temperature readings and proper thermal management on MT8196/MT6991
devices.
While at it, convert mode defines to enum.

MT8196/MT6991 require a different version of lvts_temp_to_raw(),
specifically the multiplicative inverse of the existing implementation.
Introduce a variant of the function with inverted calculation logic to
match this requirement.
This ensures accurate raw value generation for temperature
thresholds, avoiding spurious thermal interrupts or unintended hardware
resets on MT8196/MT6991.
