Bug #3200 » weston-drmev-bug-2.md

peeter, 10/25/2019 03:22 AM

1 - the weston thread is trying acquire a lock which is held by "ithread16 2"
2 - in the "ithread16 2" backtrace, the lock has been acquired in do_intel_finish_page_flip: 10919: spin_lock_irqsave(&dev->event_lock, flags);

spin_lock_irqsave(lock, flags) = spin_lock_irq(lock) = lockmgr(lock, LK_EXCLUSIVE)

Note: not sure why in the "ithread16 2" backtrace, do_intel_finish_page_flip() appears twice. Since do_intel_finish_page_flip() acquires dev->event_lock ("drmev"), could it mean the lock is not be released? Or something else is happening. . .
