Read/Write PMU global general storage register value, | ||
GLOBAL_GEN_STORAGE{0:3}. | ||
Global general storage register that can be used | ||
by system to pass information between masters. | ||
|

The register is reset during system or power-on | ||
resets. Three registers are used by the FSBL and | ||
other Xilinx software products: GLOBAL_GEN_STORAGE{4:6}. | ||

value, PERS_GLOB_GEN_STORAGE{0:3}. | ||
Persistent global general storage register that | ||
can be used by system to pass information between | ||

|
||
This register is only reset by the power-on reset | ||
and maintains its value through a system reset. | ||
Four registers are used by the FSBL and other Xilinx | ||
software products: PERS_GLOB_GEN_STORAGE{4:7}. | ||
Register is reset only by a POR reset. | ||

What: /sys/devices/platform/firmware\:zynqmp-firmware/shutdown_scope | ||
Date: March 2020 | ||
KernelVersion: 5.6 | ||
Contact: "Jolly Shah" <[email protected]> | ||
Description: | ||
This sysfs interface allows to set the shutdown scope for the | ||
next shutdown request. When the next shutdown is performed, the | ||
platform specific portion of PSCI-system_off can use the chosen | ||
shutdown scope. | ||
|
||
Following are available shutdown scopes(subtypes): | ||
|
||
subsystem: Only the APU along with all of its peripherals | ||
not used by other processing units will be | ||
shut down. This may result in the FPD power | ||
domain being shut down provided that no other | ||
processing unit uses FPD peripherals or DRAM. | ||
ps_only: The complete PS will be shut down, including the | ||
RPU, PMU, etc. Only the PL domain (FPGA) | ||
remains untouched. | ||
system: The complete system/device is shut down. | ||
|
||
Usage: | ||
# cat /sys/devices/platform/firmware\:zynqmp-firmware/shutdown_scope | ||
# echo <scope> > /sys/devices/platform/firmware\:zynqmp-firmware/shutdown_scope | ||
|
||
Example: | ||
# cat /sys/devices/platform/firmware\:zynqmp-firmware/shutdown_scope | ||
# echo "subsystem" > /sys/devices/platform/firmware\:zynqmp-firmware/shutdown_scope | ||

What: /sys/devices/platform/firmware\:zynqmp-firmware/health_status | ||
Date: March 2020 | ||
KernelVersion: 5.6 | ||
Contact: "Jolly Shah" <[email protected]> | ||
Description: | ||
This sysfs interface allows to set the health status. If PMUFW | ||
is compiled with CHECK_HEALTHY_BOOT, it will check the healthy | ||
bit on FPD WDT expiration. If healthy bit is set by a user | ||
application running in Linux, PMUFW will do APU only restart. If | ||
healthy bit is not set during FPD WDT expiration, PMUFW will do | ||
system restart. | ||
|
||
Usage: | ||
Set healthy bit | ||
# echo 1 > /sys/devices/platform/firmware\:zynqmp-firmware/health_status | ||
|
||
Unset healthy bit | ||
# echo 0 > /sys/devices/platform/firmware\:zynqmp-firmware/health_status | ||
