FRHICommandListImmediate::EndScene 崩溃

Development Rendering
, ,
1

在FRHICommandListImmediate::EndScene()：

void FRHICommandListImmediate::EndScene()

{

check(IsImmediate() && IsInRenderingThread());

if (Bypass())

{

GetContext().RHIEndScene();

return;

}

ALLOC_COMMAND(FRHICommandEndScene)();

if (!IsRunningRHIInSeparateThread())

{

// if we aren’t running an RHIThread, there is no good reason to buffer this frame advance stuff and that complicates state management, so flush everything out now

QUICK_SCOPE_CYCLE_COUNTER(EndScene_Flush);

CSV_SCOPED_TIMING_STAT(RHITFlushes, EndScene);

FRHICommandListExecutor::GetImmediateCommandList().ImmediateFlush(EImmediateFlushType::FlushRHIThread);

}

}

里面ImmediateFlush会崩溃，我看在UE5.5之后RHIEndScene和RHIBeginScene都去掉了，对应的EndScene也没有了，请问我们在5.3里面也能直接去掉么？我看了UE 0ebb5c1这次提交，并没有上下文关联，就单纯的把RHIEndScene和RHIBeginScene删掉了，我们如果想在5.3删掉还有其他关联逻辑需要注意么？

另外，我发现新版本的UE在一些强制Flush的地方都进行了删除，比如FVulkanTexture::InternalLockWrite里面：

inline void FVulkanTexture::InternalLockWrite(FVulkanCommandListContext& Context, FVulkanTexture* Surface, const VkBufferImageCopy& Region, VulkanRHI::FStagingBuffer* StagingBuffer)
{
    Code
    VulkanRHI::vkCmdCopyBufferToImage(StagingCommandBuffer, StagingBuffer->GetHandle(), Surface->Image, VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL, 1, &Region);
    {
       FVulkanPipelineBarrier Barrier;
       Barrier.AddImageLayoutTransition(Surface->Image, VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL, Surface->GetDefaultLayout(), SubresourceRange);
       Barrier.Execute(CmdBuffer);
    }
 
    Surface->Device->GetStagingManager().ReleaseBuffer(CmdBuffer, StagingBuffer);
 
    if (GVulkanSubmitOnTextureUnlock != 0)
    {
       Context.GetCommandBufferManager()->SubmitUploadCmdBuffer();
    }
}

最后UploadCmdBuffer这部分就被删掉了，我们发现这一块我们也会崩溃

<br/>

想问下在这些地方UE取消Flush是为了性能考虑么？UE做了什么机制能保证去掉之后的同步么？那么我们为了解决崩溃能否在5.3版本也去掉？

<br/>

另外同步下，我们关闭了RHI线程

Hi，

你好，我看到这两个崩溃都是发生在关掉RHIThread的情况下，请问为什么要关闭RHIThread？

主要是大部分情况下，我们测试的都是开启RHIThread，尤其是发布后的游戏，虽然我们后续在开发过程中遇到过比如开启ImmediateMode，ForceRHIBypass，OneThead等命令时遇到的问题，但因为RHI接口一直有大的改动，所以不确定是否能解决你们的问题。在5.3的版本里，不排除关闭RHIThread有什么潜在问题我们没发现，所以尽可能开启RHIThread。

关于第一个问题，我认为是不应该删除的，因为在关掉RHIThread的情况下，这里需要对RHI的资源做释放，否则可能会造成内存泄漏。在开启RHIThread的情况下也会做同样的事情（FRDGBuilder.EndFlushResourcesRHI)。

关于第二个问题，我们重构了VulkanRHI上传数据的实现(https://github.com/EpicGames/UnrealEngine/commit/2b8510a2b6f7b927671c91f52ed912929a09b257\)，不过从描述里看，并没有描述是修复某个crash，看起来应该跟提升并行性有关系。我在内部的jira里也没有搜到类似的问题。

这两个问题可能要先看看打开RHIThread是否有改善，如果实在不能开启，可能要更深入的看一下可能是什么问题造成的。

5

1 我们之前是测试发现开启RHIThread在PSO Cache的时候会发生一些崩溃，所以关了，所以在Android上的话，开启RHIThread是会更稳定么？

2 另外我们发现关了RHIThread性能是会下降20-30%左右的，在后续还是想开启的，想问下后面更新版本RHIThread稳定性和性能是都会有提升么？

3 目前小版本是关了RHIThread，后面我们也是打算要开启的，如果要开启的话，一条路径是不升级引擎，那就需要在现在版本上修复现有的开启RHIThread的崩溃问题，二是升级到最新版本，享受新本的稳定性和性能的提升(如果2是成立的话)，你们有什么建议么

6

建议还是开启，PSO Cache如果因为开启了RHIThread崩溃，可以把信息发给我，我可以看看有什么线索。因为我们都是开启RHI Thread的，所以很少会发现关掉RHIThread一些问题。

RHIThread开启应该不会有稳定性问题，也许有不过后续肯定都修了。性能理论上比不开启是要好一点的，至少可以跟渲染线程并行一部分时间。

如果能升级到最新版的引擎最好，有几个原因，一个是之前发现的问题肯定都修复了，二是即便遇到任何问题，我们都会第一时间修复，如果版本跟我们当前版本差距很大的话，我们的开发团队也很难维护以前的版本，所以其实会问题更多。

第一个机型是ZTE A2023H的堆栈，这个是Sharp Aquos Zero 2的堆栈

9

你能试一下配置r.Vulkan.EnablePipelineLRUCache=1，然后测试一下吗

10

试了下，开启r.Vulkan.EnablePipelineLRUCache=1之后 编译PSO会超级慢，隔段时间会闪个弹窗，log有如下报错：

LogVulkanRHI: Error: Android RemoteCompileServices Failed to create graphics pipeline.

11

请问这些是什么设备？ 另外能否试一下设置 r.pso.EnableAsyncCacheConsolidation 0​

12

机型是中兴 天玑41ultra, 8gen1,我查了下5.3.2版本没你发的这个var，不过我设置了GVulkanPSOForceSingleThreaded = (int32)ESingleThreadedPSOCreateMode::All;禁掉PSOAsync好像好了

13

好的，感谢提供信息。可以针对这种设备增加一个DeviceProfile，单独设置这个参数。或者设置r.pso.CreateOnRHIThread=1是不是应该也可以？
