What was added: * Framebuffer * NativeActivity * NV Services * IOCTL Handler * NV Devices: * * /dev/nvmap - 0xC0080101, 0xC0080103, 0xC0200104, 0xC0180105, 0xC00C0109, 0xC008010E * * /dev/nvhost-as-gpu * * /dev/nvhost-channel - 0x40044801, 0xC0104809, 0xC010480B, 0xC018480C, 0x4004480D, 0xC020481A, 0x40084714 * * /dev/nvhost-ctrl * * /dev/nvhost-ctrl-gpu - 0x80044701, 0x80284702, 0xC0184706, 0xC0B04705, 0x80084714 * SVCs: * * SetMemoryAttribute * * CreateTransferMemory * * ResetSignal * * GetSystemTick * Addition of Compact Logger What was fixed: * SVCs: * * SetHeapSize * * SetMemoryAttribute * * QueryMemory * A release build would not set CMAKE_BUILD_TYPE to "RELEASE" * The logger code was simplified
