Test exercise possiblity to restore previously saved GuC state, cleared during VF states transitions and reset. Setup involves VF(s) provisioning (either auto or manual), enablement and driver probe. Additionally, runtime power management is disabled to prevent VF suspend. VF run state (pause-resume) is controlled to put VF in a state allowing to perform save/restore operations. GuC state as well as GGTT and LMEM raw data is read via relevant debugfs attributes for later restore. VF health in pre- and post-migration phase is verified by running simple workload. SRIOV debugfs library functions added to support tested scenario: - send VF control commands - get/set GuC state, GTTT and LMEM data - trigger GGTT relocation Note, test currently requires xe driver built with SRIOV debug flag: CONFIG_DRM_XE_DEBUG_SRIOV=y Cc: Tomasz Lis Cc: Michał Wajdeczko Cc: Marcin Bernatowicz Cc: Lukasz Laguna Cc: Jakub Kolakowski Cc: Satyanarayana K V P Adam Miszczak (2): lib/xe/xe_sriov_debugfs: Add VF save/restore related functions tests/xe_sriov_migration: VF fake migration validation lib/xe/xe_sriov_debugfs.c | 252 ++++++++++++++++++++++++++ lib/xe/xe_sriov_debugfs.h | 31 ++++ tests/intel/xe_sriov_migration.c | 297 +++++++++++++++++++++++++++++++ tests/meson.build | 1 + 4 files changed, 581 insertions(+) create mode 100644 tests/intel/xe_sriov_migration.c -- 2.39.1
