| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently array of fix length PM_API_MAX is used to cache the pm_api version (valid or invalid).

| | | | | | | | | | | | | | | | | | Add sysfs interface to set boot health status from user space. Add API used by this interface to communicate with firmware. 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.

| | | | | | | | | | | | | | | | | | The Linux shutdown functionality implemented via PSCI system_off does not include an option to set a scope, i.e. which parts of the system to shut down.

When the next shutdown is performed, the platform specific portion of PSCI-system_off can use the chosen shutdown scope.

* firmware: xilinx: fix debugfs write handlerJann Horn2019-03-181-11/+4
| | | | | | | | | | | | | | | | | | | - Userspace wants to write a string with `len` bytes, not counting the terminating NULL, so we should allocate `len+1` bytes. It looks like the current code relied on having a nullbyte directly behind `kern_buff`, which happens to work reliably as long as `len` isn't one of the kmalloc size classes. - strncpy_from_user() is completely wrong here; userspace is giving us a (not necessarily null-terminated) buffer and its length. strncpy_from_user() is for cases in which we don't know the length. - Don't let broken userspace allocate arbitrarily big kmalloc allocations. Just use memdup_user_nul(), which is designed precisely for things like this.
