If enable_eudebug toggle was previously off, it is impossible to turn it off in case there is _any_ open debugger fd. Keep track of all opened debugger fds in lib/xe_eudebug and close any leftover ones before attempting to restore enable_eudebug state. Change pthread_join to pthread_timedjoin_np in discovery-race* and discoery-empty* tests to avoid hang before reaching cleanup. Add retry mechanism in xe_eudebug_enable to allow the postclose handler to finish. Abort on unsuccessful cleanup to not leave the environment in potentially dirty state. v2: - Preserve skip behavior in xe_eudebug_enable v3: - Improve xe_eudebug_enable logging - Move session tracking to lib/xe_eudebug - Use timedjoin in discovery-empty* v4: - fix commit msg typo (Dominik) - remove wrong 'debugger reconnected' log that was printed also for initial connection and change code reuse/organization for attach/reattach functions (Dominik) v5: - move assertion and list entry creation out of critical section (Piotr) Christoph Manszewski (3): xe/xe_eudebug: Add reattach function and make plain connect private lib/xe/xe_eudebug: Track active debugger sessions and close when disabling lib/xe/xe_eudebug: Get drm card sysfs path Dominik Karol Piątkowski (2): tests/xe/xe_eudebug: Change pthread_join to pthread_timedjoin_np lib/xe/xe_eudebug: Modify toggle error handling lib/xe/xe_eudebug.c | 214 +++++++++++++++++++++++++------- lib/xe/xe_eudebug.h | 2 +- tests/intel/xe_eudebug.c | 13 +- tests/intel/xe_eudebug_online.c | 6 +- 4 files changed, 181 insertions(+), 54 deletions(-) -- 2.47.1
