# TEMP_CONTROL for nvOC v0019-2.0 by leenoox
#
# Based on the original code by Maxximus007
#
# Changelog:
# v=0001 : leenoox
# Set higher process and disk I/O priorities - Temp control is essential service
# Auto detection of number of GPU's
# Only set, adjust and display available GPU's, dynamic variables creation
# Numeric check of the return values from nvidia-smi (looking for numbers only, anything else = error)
# Reboot if GPU error detected and watchdog didn't react for 60 seconds (act as a backup watchdog)
# Added query delay to nvidia API (no burst spamming, added 0.5 sec delay, prevent overload), helps reduce stale shares
# New (improved) display output including colors and bold text
# Fixed the log file handling (Bug fix: Previous implemantation was not limiting the file size)
# Removed repetitive GPUFanControlState setting, it only needs to be set once, not every cycle (prevent API overload)
# Workaround for some 1050's reporting "Unknown" or "ERR" when power.draw is queried from nvidi-smi
# v=0002 : Stubo: Added secondary fix for 1050's reporting "[Not Supported]" or "[Unknown Error]" when power.draw is
# queried from nvidia-smi (a.k.a. bleed issue of power.draw)
# v=0003 : Papampi: Telegram alerts
#
# v=0004 : Papampi:
# MAXIMAL_FAN_SPEED
# v=0005 : LukePicci
# Relocate nvOC to arbitrary install directory
# v=0006 : papampi (suggestion by abdeldev)
# Use sysrq reboot, to prevent freeze/hang
# v=0007 : LuKePicci
# Reduce calls to nvidia-smi and nvidia-settings
# v=0008 : Spiral
# Add loop to shutdown rig if SHUTDOWN_TEMP exceeded
