| ==Changelog==
| |
| '''Ubuntu Bionic 5.1.2'''
| |
| * RAM clocking greatly improved
| |
| ** Read wiki's RAM OC guide before trying higher rates.
| |
| * Fixed a critical BT pairing issue
| |
| * More Joycon clones now work
| |
| * And more
| |
| | |
| '''Ubuntu Bionic 5.1.0'''
| |
| *Kernel/Driver changes
| |
| **RAM OC support of 2133 for T210 and 3000 MHz for T210B01
| |
| **Improved calibration support for Lite Gamepad (Sio). Needs hekate v6.0.5 v2 or newer. Use the Dump Joy-Con BT.
| |
| **Fixed an issue where some Taishin/Silicon Power SD cards where they would fail to init
| |
| **Several extra checks were added for SD Card UHS DDR200 tuning.
| |
| **Any card that requires the Sandisk method of tuning and fails these checks is barred from using it and they fallback to UHS SDR104.
| |
| **ddr200_disable is now removed, since it was abused and no one reported the issue to the proper channels.
| |
| **Stick Calibration is now tighter for Joy-Con/Pro-Con/Lite controllers when factory or user calibration is empty or can't be acquired.
| |
| **Fixed an old railed Joy-Con issue which could make UART communications hang if it was plugged during suspend procedure.
| |
| **Added Generic and FTDI USB serial drivers as modules
| |
| **Support unfused BRCM4354 mascaraed as BRCM4356 WiFi chip on some old Switch units
| |
| **Add support for WiFi 5 GHz bonding restriction of VHT80 and VHT160 to mitigate possible bugs in the WiFi firmware if needed.
| |
| *Ubuntu/Userspace changes
| |
| **mem-bench command was added. It is able to use most of RAM bandwidth. Use together with Perf OC All power profile for better results.
| |
| **Frequency reported there is the actual real frequency of RAM. Reason why it changes everytime, because of clock jitter.
| |
| **Fixed an issue with jc-dump-ltk command failing to acquire Pro-Con or Joy-Con Grip MAC addresses and LTK properly.
| |
| *Boot Stack changes
| |
| **Initramfs
| |
| **-- Failed to find rootfs issues can now also be debugged via USB. Simply follow the instruction in the Red screen and connect to a PC.

| |
| ***[joycon_02]
| |
| ***type=3
| |
| ***mac={MAC address of Procon}
| |
| ***host={MAC address of Switch}
| |
| ***ltk={LTK (connection key) of Procon}
| |
| **And fill in the {brackets} with the correct information. All of it can be acquired from the jc-dump-ltk command when you connect Procon via USB.
| |
| **Reminder that if the file is created anew, the line-endings MUST be Unix based. CRLF are not supported.
| |
| **INI config
| |
| ***-- Added ram_oc_vdd2, ram_oc_vddq for fine tuning RAM voltage and improved ram_oc key. Read below for more.

| ***Any card that requires the Sandisk method of tuning and fails these checks is barred from using it and they fallback to UHS SDR104.
| |
| ***<code>ddr200_disable</code> is now removed, since it was abused and no one reported the issue to the proper channels.
| |
| **Stick Calibration is now tighter for Joy-Con/Pro-Con/Lite controllers when factory or user calibration is empty or can't be acquired.
| |
| **Fixed an old railed Joy-Con issue which could make UART communications hang if it was plugged during suspend procedure.
| |
| *Userspace:

| |
| * uenv.txt changed, read uenv_readme.txt. It's simple to transfer over custom settings..
| |
| * Reboot action can now be defined in new uenv.txt. Reboot back into Linux by changing `reboot_action=` from `bootloader` to `via-payload`.
| |
|
| |
|
| Apps Changes:
| | For a complete installation guide and a list of features, check out the [https://wiki.switchroot.org/wiki/linux/l4t-ubuntu-bionic-installation-guide guide on the switchroot wiki]. |
| * Full video HW decoding via new SMPV Player app (also supports youtube links).
| |
| * Full video HW encoding via ffmpeg-l4t.
| |
| * Added [https://github.com/cobalt2727/L4T-Megascript/wiki L4T-Megascript app]. You can get or build various essential stuff, apps or emulators with a single click. All configured and optimized for Switch..
| |
| * Nvpmodel was updated to include Battery charging protection limits options.
| |
| **Useful when you are constantly docked and want to protect battery's life.
| |
| **Limit gets saved and applied on boot.
| |
| **Reminder that discharging can't happen when plugged in. Even when charging is off, usb power is used to supplement system.
| |
| **So you need to discharge first if you want the battery % to go inside the limit.
| |
| **That also disables charging in sleep in order for the feature to work.
| |
| **If you reboot/shutdown, it gets disabled and re-enabled at the next L4T boot.
| |
| **As always the source is public and all L4T based projects for Switch will benefit (L4T linux distros/Lakka/Android).
| |
| | |
| '''Ubuntu Bionic 3.3.0'''
| |
| * Significant performance improvements.
| |
| **CPU arch, RAM, GPU, general latency, etc optimizations.
| |
| **Affects gui, apps, games, emus, etc.
| |
| * Significant deep sleep power draw fixes.
| |
| **Now almost all non-needed devices power off on deep sleep and ram is set to appropriate frequency..
| |
| **(Touch panel, LCD, Joycon charging and many more devices now power off in deep sleep as they should).
| |
| * IO scheduler was changed to provide way faster storage IO.
| |
| * Released 15 MiB extra ram.
| |
| * Fixed voltage calculation for OC. It should provide more stable overclocking.
| |
| * Refactored thermal management.
| |
| **Fan profiles are now the same with HOS.
| |
| **Added failsafes, throttling and force power off when very high temps for the board are reached.
| |
| * Faster boot times.
| |
| * Fixed issues with Joycon charging and Hori power on resume.
| |
| * Fixed Power button issues.
| |
| * Touch improvements.
| |
| * Added Hori and Obirds rail support.
| |
| * OTG now allows deep sleep, even if linux resides in a USB SSD.
| |
| * Various USB fixes.
| |
| * Allow fuel gauge to wake up system and power off gracefully on empty battery.
| |
| * Added support for many 3rd party docks.
| |
| **These include Genki, Zenscreen, Nexdock and anything else that uses similar methods.
| |
| **Basically, the support should reach 100% (docks that support DP via pin D).
| |
| * Fixed issues with fast charging when docked on boot.
| |
| * Fixed other issues with charging on certain edge cases.
| |
| * Fixed DP/HDMI when plugging console while sleeping.
| |
| * Fixed DP/HDMI when already docked and waking up.
| |
| * Dock led indicator now has a breathing light when sleeping.
| |
| * Add exFAT partition support (boot driver still needs to be FAT32).
| |
| * Enabled 1GB ZRAM swap.
| |
| | |
| * Status messages on booting.
| |
| * Seamless display booting (needs hekate higher than v5.5.4).
| |
| * Disabled screen blanking on idle. Dimming/Screensaver is still there and can be disabled in Brightness & Lock.
| |
| ** This will help with games/emus where gamepad is used and it does not reset idle times like mouse/keyboard.
| |
| * Fixed apt repo urls.
| |
| | |
| * NVPModel is revamped:
| |
| **Allow changing power profiles via touch.
| |
| **Added handheld power profile.
| |
| **Added fan profiles.
| |
| **Added automatic profiles based on handheld or docked.
| |
| **Added USB 3.0 disable toggle for boosting WiFi 2.4G and Bluetooth signal.
| |
| **OC profiles now do not require enabling overclock flag in sysfs.
