libnx v2.0.0

system

• Introduced multi-wait infrastructure, allowing for user mode synchronization primitives. Users are advised to stop using svcWaitSynchronization(Single) manually and move to the new wait API.
• Added UEvent and UTimer user mode synchronization primitives.
• Added full list of KernelError result codes, as well as a KERNELRESULT macro.
• Added eventActive.
• Added tmemCreateFromMemory.
• Added syscall: svcTerminateDebugProcess.
• Corrected syscalls: svcMapPhysicalMemory, svcUnmapPhysicalMemory.
• Fixed bug in ipcParseDomainResponse.
• Fixed bug in ipcPrepareHeaderForDomain.
• Added serviceSendObject.

graphics

• Major refactor and redesign of the entire libnx graphics stack.
  • Introduced NWindow (Native Window) API, allowing for direct management of a renderable surface. It is possible to create a NWindow out of a ViLayer (or other sources of an IGBP binder object); or use nwindowGetDefault to retrieve the default native window.
  • Introduced Framebuffer API (used for creating and managing a software rendered framebuffer on a NWindow).
  • Deprecated the old gfx API, scheduled for removal in the next libnx release. Users are advised to move to the new NWindow API (and Framebuffer if applicable). Please see switch-examples for more information on how to use this new API.
  • The default software rendered console backend now uses NWindow and Framebuffer instead of the old gfx API. Therefore, it is now mandatory to use consoleUpdate/consoleExit.
  • Optimized software console scrolling; now using 128-bit copies and RGB565 framebuffer format (which requires 50% less memory bandwidth).
  • Completely redesigned Nvidia ioctl wrapper objects, now more closely matching official logic.
  • Miscellaneous fixes in vi, parcel, IGBP, etc code.
• Added vi commands: viSetContentVisibility, viGetDisplayLogicalResolution, viSetDisplayMagnification, viSetDisplayPowerState, viSetDisplayAlpha, viGetDisplayMinimumZ, viGetDisplayMaximumZ, viSetLayerSize, viSetLayerZ, viSetLayerPosition.
• Improved ViScalingMode enum.

applet

• Introduced libapplet (library applet) launching support.
• Added swkbd (software keyboard) libapplet wrapper.
• Added applet commands: appletPopLaunchParameter, appletPushToGeneralChannel, appletSetTerminateResult, appletSetMediaPlaybackState.
• Added account applet wrapper: accountGetPreselectedUser.
• Added libappletRequestHomeMenu, libappletRequestJumpToSystemUpdate.
• Added AppletStorage object.
• Added AppletHolder object.
• Added LibAppletArgs object.
• Corrected and added missing AppletFocusState and AppletFocusHandlingMode enum values.
• Now using domains for am services.

usb

• Added usb:hs service wrapper.
• Now using domains for usb:ds.
• Miscellaneous fixes and refactoring.

other services

• Added fs command: fsIsExFatSupported.
• Added hid command: hidAcquireNpadStyleSetUpdateEventHandle.
• Added ldr:ro and ro:dmnt service wrappers.
• Added ns:dev commands: nsdevLaunchProgram, nsdevGetShellEvent, nsdevGetShellEventInfo, nsdevTerminateApplication, nsdevPrepareLaunchProgramFromHost, nsdevLaunchApplication, nsdevLaunchApplicationWithStorageId, nsdevIsSystemMemoryResourceLimitBoosted, nsdevGetRunningApplicationProcessId, nsdevSetCurrentApplicationRightsEnvironmentCanBeActive.
• Added pm:dmnt commands: pmdmntGetDebugProcesses, pmdmntDisableDebug.
• Added pm:shell commands: pmshellTerminateProcessByProcessId, pmshellGetProcessEvent, pmshellGetProcessEventInfo, pmshellFinalizeDeadProcess, pmshellClearProcessExceptionOccurred, pmshellNotifyBootFinished, pmshellBoostSystemMemoryResourceLimit.
• Renamed ldrDmntGetNsoInfos to ldrDmntGetModuleInfos.
• Changed psm wrapper to dynamically open and close IPC sessions instead of leaving one open at all times. Introduced PsmSession object, used to manage this session.
• Fixed IPC bug in splSetConfig.

miscellaneous

• Added sys/poll.h as an alias for poll.h.
• Fixed compatibility with C99.
• Further improvements to overall system stability and other minor adjustments to enhance the user experience.
