libnx v1.4.0

system

• Added support for C11 threads, which are preemptively multitasked and load balanced across cores.
• Added Event object, which wraps kernel revent/wevent handles with optional autoclear.
• Changed CondVar interface to have the mutex be passed to condvarWait* instead of condvarInit, which is consistent with both the concept of a condition variable and with other common threading APIs.
• Added armGetSystemTick (which supersedes svcGetSystemTick), and armGetSystemTickFreq.
• Added rwlockInit.
• Added kernelAbove600.
• Added system calls: svcGetThreadCoreMask, svcSetThreadCoreMask.
• Added MOD0 header to binaries compiled with libnx.
• Fixed semaphoreTryWait.
• Fixed a memory leak in tmemCreate.

services

• Added bpc service (used for rebooting and shutting down the console).
• Added psm service (needed to get the battery status).
• Added ns commands: nsListApplicationRecord, nsListApplicationContentMetaStatus.
• Minor enhancements to applet service:
  • Added missing AppletType_SystemApplet initialization in applet code.
  • Added appletBeginBlockingHomeButton and appletEndBlockingHomeButton.
• The Event object is now used to return system events from service wrappers when possible, also providing the correct autoclear mode.
• Corrected fsOpenFileSystem and fsOpenFileSystemWithId.
• Corrected a bug in hidInitializeVibrationDevices.
• Corrected a bug in socket error conversion.
• Fixed nifm not initializing properly for < 3.0.0.
• Service manager (sm) session now closes properly.
• hid, irs, vi and nv services now acquire a reference to applet services.

audio

• Added audren:u service wrapper (presently requiring 3.0.0+, will be addressed in a future update).
• Added AudioDriver wrapper around audren, providing a higher level interface that can be used to mix and play sounds.

graphics

• Major rewrite and refactoring work in the gfx wrapper which brings reliability and usability improvements:
  • Removed GfxMode_TiledSingle mode due to it causing problems and potential (temporary) hardware damage.
  • The default transform behavior no longer vertically flips the framebuffer.
  • Removed gfxSetDrawFlip since it's no longer needed thanks to the change in the default transform behavior.
  • It is not necessary to call gfxWaitForVsync in most situations because gfxSwapBuffers already implicitly synchronizes with the display (this is mandated by the Android surface compositor and buffer producer system).
  • Dequeue fatal errors should be solved.
  • Simplified and streamlined logic.
  • nvgfx stripped down to the minimum that is actually necessary to allocate framebuffers.
  • Binder logic now more closely matches both Android code and official software.
  • Proper fence and event wait code is now used.
• Console code no longer performs a forced flush/swap/vblank wait when printing a newline due to performance reasons. Users of the console device must make sure that gfxFlushBuffers and gfxSwapBuffers are periodically called, preferably in the main loop of the application.
• Added experimental wrapper objects for the Nvidia driver, needed in order to use the GPU. These wrappers are still in RE phase and will be subject to change in a future release.
• Major redesign of the VI service wrapper that allows future users to use VI directly to create a display layer.
• Binder services & buffer producer wrappers were enhanced and redesigned.
  • Binder now holds less state and always uses the VI binder relay service session.
  • Added Module_LibnxBinder error codes.
  • IGraphicBufferProducer binder service wrappers now have the bq prefix and explicitly accept a Binder object.
  • Added bqCancelBuffer.
  • bqGraphicBufferInit was renamed to bqSetPreallocatedBuffer.
• Enhancements and additions to nvidia ioctl wrappers.
• Added definitions for some more Android enumerations.

miscellaneous

• The ALIGN macro was removed in favor of the C11/C++11 alignas attribute.
• Further improvements to overall system stability and other minor adjustments to enhance the user experience.
