From 644de99e86856bad3fe24a0324c06f96cee6a401 Mon Sep 17 00:00:00 2001 From: Thog Date: Sun, 19 Apr 2020 03:25:57 +0200 Subject: Implement GPU syncpoints (#980) * 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 --- .../Engine/MethodIncrementSyncpoint.cs | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 Ryujinx.Graphics.Gpu/Engine/MethodIncrementSyncpoint.cs (limited to 'Ryujinx.Graphics.Gpu/Engine/MethodIncrementSyncpoint.cs') diff --git a/Ryujinx.Graphics.Gpu/Engine/MethodIncrementSyncpoint.cs b/Ryujinx.Graphics.Gpu/Engine/MethodIncrementSyncpoint.cs new file mode 100644 index 00000000..65742ba7 --- /dev/null +++ b/Ryujinx.Graphics.Gpu/Engine/MethodIncrementSyncpoint.cs @@ -0,0 +1,19 @@ +using Ryujinx.Graphics.Gpu.State; + +namespace Ryujinx.Graphics.Gpu.Engine +{ + partial class Methods + { + /// + /// Performs an incrementation on a syncpoint. + /// + /// Current GPU state + /// Method call argument + public void IncrementSyncpoint(GpuState state, int argument) + { + uint syncpointId = (uint)(argument) & 0xFFFF; + + _context.Synchronization.IncrementSyncpoint(syncpointId); + } + } +} -- cgit v1.2.3
