* Start rewriting nvservices internals TODO: - nvgpu device interface - nvhost generic device interface * Some clean up and fixes - Make sure to remove the fd of a closed channel. - NvFileDevice now doesn't implement Disposable as it was never used. - Rename NvHostCtrlGetConfigurationArgument to GetConfigurationArguments to follow calling convention. - Make sure to check every ioctls magic. * Finalize migration for ioctl standard variant TODO: ioctl2 migration * Implement SubmitGpfifoEx and fix nvdec * Implement Ioctl3 * Implement some ioctl3 required by recent games * Remove unused code and outdated comments * Return valid event handles with QueryEvent Also add an exception for unimplemented event ids. This commit doesn't implement accurately the events, this only define different events for different event ids. * Rename all occurance of FileDevice to DeviceFile * Restub SetClientPid to not cause regressions * Address comments * Remove GlobalStateTable * Address comments * Align variables in ioctl3 * Some missing alignments * GetVaRegionsArguments realign * Make Owner public in NvDeviceFile * Address LDj3SNuD's comments
