Chris Freehill	34c977bd06	Added rsmi_dev_pci_replay_counter_get() ... Also, added code to destroy/recreate mutex if we can't get a lock within 3 seconds, when shared memory mutex is initialized.	2019-05-06 11:26:40 -05:00
Chris Freehill	5e24a77193	Add mutex for multi-process access to device sysfs files ... This commit uses a pthread mutex in shared memory to prevent almost all cases of multiple processes simultaneously reading/writing to device sysfs files. The main existing race condition is when 2 processes are starting at the same time, setting up their shared memory and mutexes. Since this is meant to prevent collisions among thread and processes, the small shared memory segments (big enough for a pthread_mutex) will persist until reboot.	2019-05-04 15:10:58 -05:00
