Ubuntu Bionic 5.1.0 Full Changelog
hekate 6.0.3 or newer is mandatory
Kernel/Driver:
- 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.
Userspace:
- Fixed an issue with
jc-dump-ltk command failing to acquire Pro-Con or Joy-Con Grip MAC addresses and LTK properly.
- SD/eMMC Dramatic Performance Increases
Support for SD card UHS DDR200 allowing for up to 200MB/s on UHS-I bus (up from 104MB/s). (Needs hekate 6.0.3).
That marks the first device in the world to even support this. (HW is 4 years older than DDR200 and doesn't provide official support).
Read performance increased by 2-20% and write by 50-200% on SD and eMMC. That's by fixing an almost 2 decades old bug.
Fixed an old Nvidia bug where it would decrease SD/eMMC performance by 60% after a deep sleep.
Decreased latency/access times and improved random transfers (4k IOPS)
Added support for SD card cache
SD Card VDDC/VDDQ regulators are now disabled on deep sleep. Increases standby times dramatically on chipped switch that use the proper SD card VDD point.
On failed inits, the SD card will now be power-cycled fully and driver will try to reduce bus timing progressively, instead of falling back to HS25 immediately. Finally, retries are now instant, instead of taking 2-5s.
- Deep Sleep
Significantly improved wake up speed on T210 and T210B01
Significantly improved deep sleep on T210B01 (increased by ~10-15 days)
Mitigated a T210B01 HW erratum and fixed several Nvidia driver bugs in SDMMC/PCIE/XUSB/USBPD drivers
- GPU DVFS for T210B01
A new mode added for T210B01 that dramatically lowers power consumption on higher GPU clocks.
That also allows GPU to reach 1228 MHz max on select binned GPUs.
GPU clocks are now properly limited by max voltage and max power, increasing safety by not exceeding pmic current limits.
That can also increase max GPU clock to 1152 MHz on select binned GPUs.
- Joy-Con/Pro-Con
Improved Sio (Lite Gamepad) init
Increased Sio input report rate to 120HZ (8ms) from 60Hz (16ms)
Reduced traffic from rumble commands
Added plug-in/removal detection via pins for railed Joy-Con
Fixed an issue where the IMU input device would not be unregistered on removal of railed or wireless Joy/Pro-Con
- XBOX Controllers
Added support for bluetooth XBOX controllers via XPAD Neo driver
As with USB ones, userspace must load the module.
- WiFi/Bluetooth
Updated firmware files to latest from HOS
Fixed several bluetooth driver bugs
- USB-PD
VCONN/VBUS is now managed on certain SKUs, increasing deep sleep dramatically.
- PCIE/XUSB
Improvements to the drivers in all fronts.
The Suspend/Resume fixes also increase deep sleep times dramatically.
Fixed an issue where USB on dock would not work if booted docked.
- Built-in IMU
Added support for STM LSM6DSO/LSM6DO and LSM6DSE 6-Axis IMU chips.
Now the driver will also automatically choose between LSM6DS3H/DSO/DSE and ICM40607
- Added HW Random engine support for T210B01
- Fixed production settings for DisplayPort on T210B01
- Fixed several pmic settings
- Many more improvements/fixes
- Chromium Widevine Support for Movie/Series Streaming Services
Chromium now supports Widevine DRM for streaming platforms. Most sites work via the normal icon.
Others, like Netflix, need the Chromium Streaming one from the app menu.
- Switch Tray Icon
The icon is now split into 2 sections. The Switch icon for tools and the Text profile one that allows Power/Fan management.
The following features were added to the icon:
Added Reboot 2 Config app for rebooting to a hekate boot entry with 2 simple steps
Added OLED display color modes
Added Joy-Con Controls Mapping help. Shows how Joy-Con are mapped to keyboard/mouse and how to enable/disable it.
- Theme
Unity Dash, the apps side bar, was updated to a modern flat theme.
- Apps
Added tegrastats-l4t with better formatted output. Useful for live info and overlays. Can be launched from the Switch tray icon.
Added jc-dump-ltk for dumping Bluetooth LTK key when user connects Pro Controller via USB. Can be also used for getting LTK from Joy-Con via Grip.
- Bluetooth
Bluetooth now gets disabled in Sleep, for not needing user to turn off controllers manually.
This also allows the whole wifi/bt combo chip to power down during sleep and thus decreasing power consumption.
- Optional support for DTS audio encoder (dcaenc) for DP/HDMI was added. If wanted, apt package is
alsa-lib-dcaenc.
- Many more improvements/fixes
- L4T Loader
SD Card UHS DDR200 mode support (needs hekate 6.0.3 or newer)
Allow early 2019 Samsung ram to be overclocked to 2133MHz for T210B01 (Mariko)
- INI config
bt_ertm_disable allows disabling Bluetooth ERTM which might hinder usage of some Bluetooth devices
ddr200_disable allows disabling the automatic SD Card UHS DDR200 support
gpu_dvfsc allows dramatically decreasing GPU power consumption for Mariko on high clocks and allowing for higher clocks also
limit_gpu_clk allows limiting max GPU clocks in case gpu_dvfsc is used and GPU can't withstand lower voltage
As always, check README_CONFIG.txt for more info.
- Support for beefy pmic type of T210B01 devboards in U-BOOT

Ubuntu Bionic 3.4.0 Full Changelog
- Better performances in many scenarios (As always that should affect apps/games/emus/etc)
- Significant better deep sleep. (Measured at 582 hours. 440% better).
- Faster wake up from sleep.
- Saved 240MB ram (fb and active file page pool, aka always used pool)
- Memory remapping 800%-2000% speed up. Mostly used by emulators and VMs (and lot in android).
- Some other memory optimizations, plus enabled huge ram pages
- Faster kernel and OS boot.
- Fixed tearing issues for NVDEC/NVENC. (video hw accel)
- Lower latency for frame end calcs for builtin display
- Fixed Hori pads for joycond
- Fixed an issue where it would make railed jc to disconnect on rumble
- Joycon/Procon rumble was improved and intensity tuned for better user experience
- Kernel now uses the proper display panel init/deinit by checking panel id
- Improved dock/undock script
- Touch stays enabled now in dock mode. Users that use docks that do not cover the screen can use it as alternative input.
- Added low ram protection. Now instead of hanging for minutes it will only stutter for seconds until oom occurs and recovers ram
- Better seamless display on boot
- 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:
- Full video HW decoding via new SMPV Player app (also supports youtube links)
- Full video HW encoding via ffmpeg-l4t
- Added 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)
