[PATCH i-g-t 0/6] add test to validate fallback

[PATCH i-g-t 0/6] add test to validate fallback

[Kunal Joshi]

[1] provides debugfs interfaces to force link training
failures, retrain link, set/get current/max link rate/lane count.

add new test using newly exposed interfaces to validate fallback.

[1] https://patchwork.freedesktop.org/series/133624/

Kunal Joshi (6):
  lib/igt_kms: add DP link management helper functions
  lib/igt_kms: add helper to set connector link status
  lib/igt_kms: allow set and reset value to be same
  lib/igt_kms: add function to reset link params
  tests/intel/kms_dp_fallback: add test for validating fallback

[PATCH i-g-t 1/6] lib/igt_kms: add DP link management helper functions

[Kunal Joshi]

Added helper functions for below
- read current/max link_rate/lane_count
- forcing link retraining
- forcing link training failures
- read pending retrain
- read pending link training failures
- checking output supports forcing lt failures
- force link_rate/lane_count

v2: combine all link training debugfs in one patch (Imre)
    remove unwanted valid output check (Imre)
    return link_rate/lane_count marked with '*' or an error (Imre)

[PATCH i-g-t 3/6] lib/igt_kms: allow set and reset value to be same

[Kunal Joshi]

allow set and reset value to be same, let the caller handle
this scenario instead.

example scenario where this is required.
i915_dp_force_link_rate should be auto before starting test
should be auto at exit

v2: handle the scenario at caller side

[PATCH i-g-t 5/6] tests/intel/kms_dp_fallback: add test for validating fallback

[Kunal Joshi]

add test to valdiate fallback for DP connector,
eDP subtest will be added later.

How does test validates fallback?
- test start by doing initial modeset on default mode
   (if connector is DP then we enable just that connector,
    if its DP-MST we enable all on the same topology)
- force link training failures and retrain until we reach
  lowest param or retrain is disabled
- expect hotplug and link-status to turn bad
- expect link params reduce after fallback

v2: add test for mst (imre)
    refresh mode list (imre)
    monitor got hotplugs (imre)
    check link parameter are reduced (imre)

v3: call check_fn (Santosh)

v4: handle buggy lg monitor (Imre)
    remove reset in between (Imre)

v5: fit modes wrt to bw in non-mst case as well

v6: remove LT_FAILURE_SAME_CAPS (Imre)
    explain LT_FAILURE_REDUCED_CAPS to be 2 (Imre)
    combine infra for mst and non-mst case (Imre)
    call igt_reset_link_params before setup (Imre)
    Avoid duplication setting prev_(link_rate/lane_count) (Imre)
    use the cached property name here instead of hard-coding it (Imre)
    move test logic to function (Imre)
    remove extra w/s (Imre)
    remove braces in one liners (Imre)
    enhance igt_info message (Pranay)

At the call-site it's not clear what link_param=0/1 means. Instead of
that param I'd rather add debugfs_connector_read/write helpers and
export these functions with a self-descriptive name (i.e. stg. like
igt_get_dp_current_link_rate/lane_count()).

Not sure why O_DIRECTORY is used here and O_RDONLY elsewhere. This and
all the functions below could use common
debugfs_connector_read/write helpers discussed above.

force_reset would describe better what the flag does.

Someting like kms_dp_linktrain_fallback.c would be more descriptive.

prop_id is the same ID for the PATH property, attached to all MST
connectors, so it will be the same for two MST connectors that are on
different links. Instead, you could compare the root connector ID part of
connector_path which is cached already in output/connector_output->config and
has the <root connector ID>-<port ID>[-<port ID>...] format.

This should check bounds for the mst_outputs array.

Missing array bounds check.

Could use either the '*array[]' or '**array' syntax consistently
everywhere.

This won't work for modes requiring joined pipes, could add support
for that later leaving a TODO: comment here.

I suppose this and the above call should only do a
DRM_MODE_ATOMIC_TEST_ONLY commit, without actually committing the state.

kmstest_set_connector_link_status() does commit the state besides
setting the property, so a separate commit shouldn't be needed.

[PATCH i-g-t 1/6] lib/igt_kms: add DP link management helper functions

[Kunal Joshi]

Added helper functions for below
- read current/max link_rate/lane_count
- forcing link retraining
- forcing link training failures
- read pending retrain
- read pending link training failures
- checking output supports forcing lt failures
- force link_rate/lane_count

v2: combine all link training debugfs in one patch (Imre)
    remove unwanted valid output check (Imre)
    return link_rate/lane_count marked with '*' or an error (Imre)
v3: add debugfs_connector_read/write helpers (Imre)
v4: use strlen (Imre)
    rename star_ptr -> marked_ptr (Imre)
    use O_RDONLY (Imre)
