* Implement GPU syncpoints
This adds support for GPU syncpoints on the GPU backend & nvservices.
Everything that was implemented here is based on my researches,
hardware testing of the GM20B and reversing of nvservices (8.1.0).
Thanks to @fincs for the informations about some behaviours of the pusher
and for the initial informations about syncpoints.
* syncpoint: address gdkchan's comments
* Add some missing logic to handle SubmitGpfifo correctly
* Handle the NV event API correctly
* evnt => hostEvent
* Finish addressing gdkchan's comments
* nvservices: write the output buffer even when an error is returned
* dma pusher: Implemnet prefetch barrier
lso fix when the commands should be prefetch.
* Partially fix prefetch barrier
* Add a missing syncpoint check in QueryEvent of NvHostSyncPt
* Address Ac_K's comments and fix GetSyncpoint for ChannelResourcePolicy == Channel
* fix SyncptWait & SyncptWaitEx cmds logic
* Address ripinperi's comments
* Address gdkchan's comments
* Move user event management to the control channel
* Fix mm implementation, nvdec works again
* Address ripinperi's comments
* Address gdkchan's comments
* Implement nvhost-ctrl close accurately + make nvservices dispose channels when stopping the emulator
* Fix typo in MultiMediaOperationType
* 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* Remove unused code and outdated comments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
* Refactoring HOS folder structure
Refactoring HOS folder structure:
- Added some subfolders when needed (Following structure decided in private).
- Added some `Types` folders when needed.
- Little cleanup here and there.
- Add services placeholders for every HOS services (close#766 and #753).
* Remove Types namespaces
