Academic Research

Tinkertoy: Build your own operating systems for IoT devices (Best Paper Award)

Tinkertoy provides a set of modular operating system components from which developer can assemble a custom IoT system that provides precisely the functionalities needed by a particular device.

Technical Research

RealtekCardReader: Unleash the full potential of your SDXC UHS-I cards on macOS

• Derived the device specification from undocumented Linux driver.
• Designed and implemented the driver for macOS to deliver the best performance.
• Designed and implemented the missing Secure Digital protocol stack for macOS.
• Patched Apple’s reporter plugin to recognize Realtek SD card readers as native ones.

WhateverGreen: Various patches necessary for certain Intel/AMD/NVIDIA GPUs on macOS

Conducted a series of reverse engineering research on Apple’s graphics drivers and implemented fixes and missing components for PCs and laptops.

• Resolved the glitch due to incorrectly optimized Display Data Buffer on Ice Lake.
• Added support for smooth brightness transition on Ivy Bridge and later.
• Fixed the kernel panic due to incorrectly calculated amount of DVMT pre-allocated memory on Ice Lake.
• Added support for all valid Core Display Clock frequencies on Ice Lake.
• Added support for LSPCON chips to enable DisplayPort to HDMI 2.0 output on Skylake and later.
• Fixed the infinite loop when the driver sets up HDMI connections with a higher pixel clock on Coffee Lake.
• Fixed the kernel panic due to an invalid maximum link rate reported by DPCD on Coffee Lake.
• Fixed the kernel panic due to an unsupported amount of DVMT pre-allocated memory on Broadwell and later.
