[igt-dev] [PATCH i-g-t v2 1/2] igt/tests/kms_dp_tiled_display: kms test for display port tiled displays

[Madhumitha Tolakanahalli Pradeep]

This test validates the tiled DP displays to display a test pattern
seamlessly across the two tiles. It validates the transcoder port
sync feature on i915 to get a tearfree tiled display output.

Related kernel work patches-
https://patchwork.freedesktop.org/series/59837/#rev4.

This test can eventually be extended to cover tiled display support
on other connector types.

[igt-dev] [PATCH i-g-t v2 2/2] lib/igt_kms: added tile property parser

[Madhumitha Tolakanahalli Pradeep]

The tile property parser parses the connector tile property obtained
from connector's Display ID block and set per connector.

This patch looks good to me:

Reviewed-by: Simon Ser <simon.ser@intel.com>

However it should be pushed *before* patch 1 of the series
"igt/tests/kms_dp_tiled_display: kms test for display port tiled

`git rebase -i`.
