A BREAK resets connected 16a7ec9371SChristopher Bostic device's logic and preps it to receive further commands 17a7ec9371SChristopher Bostic from the master. 18a7ec9371SChristopher Bostic 192fc95e04SJoel StanleyWhat: /sys/bus/platform/devices/../fsi-master/fsi0/slave@00:00/term 20a7ec9371SChristopher BosticDate: May 2017 21a7ec9371SChristopher BosticKernelVersion: 4.12 222fc95e04SJoel StanleyContact: linux-fsi@lists.ozlabs.org 23a7ec9371SChristopher BosticDescription: 24a7ec9371SChristopher Bostic Sends an FSI terminate command from the master to its 25a7ec9371SChristopher Bostic connected slave. A terminate resets the slave's state machines 26a7ec9371SChristopher Bostic that control access to the internally connected engines. In 27a7ec9371SChristopher Bostic addition the slave freezes its internal error register for 28a7ec9371SChristopher Bostic debugging purposes. This command is also needed to abort any 29a7ec9371SChristopher Bostic ongoing operation in case of an expired 'Master Time Out' 30a7ec9371SChristopher Bostic timer. 31a7ec9371SChristopher Bostic 322fc95e04SJoel StanleyWhat: /sys/bus/platform/devices/../fsi-master/fsi0/slave@00:00/raw 33a7ec9371SChristopher BosticDate: May 2017 34a7ec9371SChristopher BosticKernelVersion: 4.12 352fc95e04SJoel StanleyContact: linux-fsi@lists.ozlabs.org 36a7ec9371SChristopher BosticDescription: 37a7ec9371SChristopher Bostic Provides a means of reading/writing a 32 bit value from/to a 38a7ec9371SChristopher Bostic specified FSI bus address. 39*4a851d71SJoel Stanley 40*4a851d71SJoel StanleyWhat: /sys/bus/platform/devices/../cfam_reset 41*4a851d71SJoel StanleyDate: Sept 2020 42*4a851d71SJoel StanleyKernelVersion: 5.10 43*4a851d71SJoel StanleyContact: linux-fsi@lists.ozlabs.org 44*4a851d71SJoel StanleyDescription: 45*4a851d71SJoel Stanley Provides a means of resetting the cfam that is attached to the 46*4a851d71SJoel Stanley FSI device. 47
