Run cufile tests on Thor (Tegra Linux), skip only on Orin #1422

rwgk · 2025-12-24T06:47:25Z

Description

Currently the cufile tests are skipped on all Tegra Linux systems, Orin or Thor. However, cufile is supported on Thor. This PR enables the cufile tests accordingly.

Note: This PR is a stop-gap, so that we stop skipping the cufile tests on Thor as soon as possible. Ideally cufile should provide an API to indicate if a given platform is supported, but currently that is not available.

@sourabgupta3 for visibility

I could test this PR only on a Thor system with a 13.0 driver (I don't want to spend the time figuring out how to flash the Thor device), which generated a number of errors (see below).

However, the new skip condition code is exercised and working correctly.
