[PATCH i-g-t 1/6] lib/igt_edid: add EDID serial extraction helpers

[PATCH i-g-t 1/6] lib/igt_edid: add EDID serial extraction helpers

[Kunal Joshi]

Add helpers to extract serial identification from EDID data.

 - edid_get_serial_string(): extract ASCII serial from descriptor 0xFF
 - edid_get_serial_number(): extract 32-bit serial from EDID header
 - edid_get_any_serial(): convenience helper that tries ASCII serial
   first, then falls back to 32-bit header serial formatted as hex

These are needed by the connector helper and USB4 switch test suite
for EDID-based display verification after dock/undock events.

[PATCH i-g-t 2/6] lib/igt_connector_helper: Add generic connector helpers

[Kunal Joshi]

Add a lightweight helper library for DRM connector operations used
by USB4 switch and other dock/undock tests:

 - igt_connector_get_connected(): enumerate connected connectors
 - igt_connector_get_info(): query name, EDID serial, and MST path
 - igt_connector_find_by_path(): PATH-based connector lookup (MST)
 - igt_connector_find_by_name(): name-based connector lookup
 - igt_connector_reprobe_all(): force reprobe all connectors by
   iterating each connector to trigger DRM core re-detection

These helpers abstract common DRM connector patterns that are needed
by multiple test suites for display enumeration and verification.

[PATCH i-g-t 3/6] lib/igt_serial: add generic serial communication helper

[Kunal Joshi]

Add a reusable serial communication library for host-to-device

 - igt_serial_open()/close(): lifecycle with configurable baud rate
 - igt_serial_send()/read(): raw data transfer
 - igt_serial_command(): send command and capture response
 - igt_serial_flush(): drain stale data from receive buffer
 - igt_serial_set_timeout(): adjust per-operation VTIME timeouts

Used by lib/igt_usb4_switch to communicate with the Microsoft USB4
Switch 3141 over its serial/USB interface.

[PATCH i-g-t 4/6] lib/igt_usb4_switch: add helper library for USB4 Switch 3141

[Kunal Joshi]

Add a control library for the Microsft USB4 Switch 3141 test equipment,
used for automated USB4/Thunderbolt dock/undock testing:

 - usb4switch_init()/deinit(): lifecycle with
   .igtrc config or autodiscovery
 - usb4switch_port_enable()/disable(): port control with optional HW delay
 - usb4switch_get_active_port(): query current port state
 - usb4switch_get_voltage_mv()/get_current_ma(): VBUS monitoring
 - usb4switch_get_orientation(): USB-C cable orientation

[PATCH i-g-t 5/6] tests/kms_feature_discovery: add basic usb4 switch discovery

[Kunal Joshi]

Add a 'usb4-switch' subtest that verifies the Microsoft USB4 Switch
3141 is reachable. The test initializes the switch library and queries
the active port to confirm communication works.

This enables CI to detect when USB4 switch hardware is available
before running the full kms_usb4_switch test suite.

[PATCH i-g-t 6/6] tests/intel/kms_usb4_switch: Add USB4 switch test suite

[Kunal Joshi]

Add a comprehensive test suite for USB4/Thunderbolt dock/undock and
port switching scenarios using the Microsoft USB4 Switch 3141:

 - dock-undock: Basic dock/undock cycles with display verification
 - dock-undock-sr: Dock/undock with suspend/resume stability
 - dock-undock-during-suspend: Dock while system is suspended
 - switch: Port-to-port switching with display verification
 - switch-sr: Port switching with suspend/resume stability
 - switch-during-suspend: Port switch during suspend via HW delay

Summary
-------

  **FAILURE**

  Serious unknown changes coming with XEIGTPW_14620_BAT absolutely need to be
  verified manually.
  
  If you think the reported changes have nothing to do with the changes
  introduced in XEIGTPW_14620_BAT, please notify your bug team (I915-ci-infra@lists.freedesktop.org) to allow them
  to document this new failure mode, which will reduce false positives in CI.

We are trying to get the timings so rather than a generic name 
serial_string, can this be replaced with get_detailed_timings ?

Can strncpy() be used instead?

The contents of these are already present in lib/igt__kms.c

Instead of a new file, can these be exported from lib/igt_kms.c ?

Spec section 3.10.3.1
defines tag FFh as Display Product Serial Number Descriptor, not a 
detailed timing descriptor

strncpy() is not a better fit here. The EDID serial field is a
fixed-width 13-byte payload, not a NUL-terminated C string. Copying the
bounded payload with memcpy(), then explicitly NUL-terminating the
destination and trimming trailing whitespace/newline, matches the EDID
encoding better.

Wasn't able to find similar helper that maybe already present,
Could you please point to those function names?
> Instead of a new file, can these be exported from lib/igt_kms.c ?
It was intentional, since igt_kms is already over 8k lines, want to have 
separate lib's grouped by entity,
In this case created connector_helper for having all connector related 
helpers at one place.

Kept it as a local alias since this pattern is used widely in IGT for
function-local knobs such as timeout/iterations/count, and it makes call
sites a bit easier to read when reused multiple times.

That said, since this one is not modified, I can make it const to 
express that more clearly.

[PATCH i-g-t 1/6] lib/igt_edid: add EDID serial extraction helpers

[Kunal Joshi]

Add helpers to extract serial identification from EDID data.

 - edid_get_serial_string(): extract ASCII serial from descriptor 0xFF
 - edid_get_serial_number(): extract 32-bit serial from EDID header
 - edid_get_any_serial(): convenience helper that tries ASCII serial
   first, then falls back to 32-bit header serial formatted as hex

These are needed by the connector helper and USB4 switch test suite
for EDID-based display verification after dock/undock events.
