The softlockup_panic sysctl is currently a binary option: panic
immediately or never panic on soft lockups.
Panicking on any soft lockup, regardless of duration, can be overly
aggressive for brief stalls that may be caused by legitimate operations.
Conversely, never panicking may allow severe system hangs to persist
undetected.
Extend softlockup_panic to accept an integer threshold, allowing the
kernel to panic only when the normalized lockup duration exceeds N
watchdog threshold periods. This provides finer-grained control to
distinguish between transient delays and persistent system failures.
The accepted values are:
- 0: Don't panic (unchanged)
- 1: Panic when duration >= 1 * threshold (20s default, original behavior)
- N > 1: Panic when duration >= N * threshold (e.g., 2 = 40s, 3 = 60s.)
The original behavior is preserved for values 0 and 1, maintaining full
backward compatibility while allowing systems to tolerate brief lockups
while still catching severe, persistent hangs.

The mediatek display driver fails to probe on mt8173-elm-hana and
mt8183-kukui-jacuzzi-juniper-sku16 in v6.14-rc4 due to missing PHY
configurations.
Enable the following PHY drivers for MediaTek platforms:
- CONFIG_PHY_MTK_HDMI=y for HDMI display
- CONFIG_PHY_MTK_MIPI_DSI=y for DSI display

Enable CONFIG_DRM_ANALOGIX_ANX7625 in the arm64 defconfig to get
display driver probed on the mt8183-kukui-jacuzzi-juniper machine.
arch/arm64/configs/defconfig has CONFIG_DRM_ANALOGIX_ANX7625=m,
but drm-ci don't have initrd with modules, so add
CONFIG_DRM_ANALOGIX_ANX7625=y in CI arm64 config.

The onboard_usb_hub driver has been updated to support non-hub devices,
which has led to some renaming.
Update to the new name (ONBOARD_USB_DEV) accordingly.

Developers can easily execute several tests on different devices
by just pushing their branch to their fork in a repository hosted
on gitlab.freedesktop.org which has an infrastructure to run jobs
in several runners and farms with different devices.
There are also other automated tools that uprev dependencies,
monitor the infra, and so on that are already used by the Mesa
project, and we can reuse them too.
Also, store expectations about what the DRM drivers are supposed
to pass in the IGT test suite. By storing the test expectations
along with the code, we can make sure both stay in sync with each
other so we can know when a code change breaks those expectations.
Also, include a configuration file that points to the out-of-tree
CI scripts.
This will allow all contributors to drm to reuse the infrastructure
already in gitlab.freedesktop.org to test the driver on several
generations of the hardware.
