From 276647789a7080c0d44ec8e4375daf0f42b73f17 Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Thu, 9 Jun 2022 10:36:13 -0400 Subject: SL-17483: Simplify ThreadPool instantiations. Now that LL::ThreadPool's constructor has subsumed the work of discovering a runtime override width, LLAppViewer::initGeneralThread() can simply pass the compile-time default width instead of redundantly checking ThreadPoolSizes. Also the default ThreadPool capacity has been bumped up to what "General" and "LLImageGL" were requesting, so they need not pass that explicitly or explain in comments why they're doing it. But until we start throwing work at the "General" ThreadPool, configure it down to 1 thread in settings.xml. --- indra/newview/llappviewer.cpp | 9 +-------- 1 file changed, 1 insertion(+), 8 deletions(-) (limited to 'indra/newview/llappviewer.cpp') diff --git a/indra/newview/llappviewer.cpp b/indra/newview/llappviewer.cpp index 3bcd4f9a49..334df4ee20 100644 --- a/indra/newview/llappviewer.cpp +++ b/indra/newview/llappviewer.cpp @@ -2183,14 +2183,7 @@ void LLAppViewer::initGeneralThread() return; } - LLSD poolSizes{ gSavedSettings.getLLSD("ThreadPoolSizes") }; - LLSD sizeSpec{ poolSizes["General"] }; - LLSD::Integer poolSize{ sizeSpec.isInteger() ? sizeSpec.asInteger() : 3 }; - LL_DEBUGS("ThreadPool") << "Instantiating General pool with " - << poolSize << " threads" << LL_ENDL; - // We don't want anyone, especially the main thread, to have to block - // due to this ThreadPool being full. - mGeneralThreadPool = new LL::ThreadPool("General", poolSize, 1024 * 1024); + mGeneralThreadPool = new LL::ThreadPool("General", 3); mGeneralThreadPool->start(); } -- cgit v1.2.3 From 50dca86f64a167fe0db901310d04784b2f0dfa1f Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Thu, 9 Jun 2022 12:06:23 -0400 Subject: SL-17483: Recast LLImageDecodeThread as a facade for ThreadPool. Remove all references to LLQueuedThread (but emulate a couple bits of its API such as handle_t and getPending()). Migrate ImageRequest into llimageworker.cpp. It has never been part of LLImageDecodeThread's public API. Remove ImageRequest tests. Remove all references to LLImageDecodeThread::pause(). The idea of pausing another thread is bizarre to me, and LLThreadPool has no such operation. Nor does it have an abortRequest(). --- indra/newview/llappviewer.cpp | 11 ++++------- 1 file changed, 4 insertions(+), 7 deletions(-) (limited to 'indra/newview/llappviewer.cpp') diff --git a/indra/newview/llappviewer.cpp b/indra/newview/llappviewer.cpp index bc38a96ef2..ae0c9d4dd6 100644 --- a/indra/newview/llappviewer.cpp +++ b/indra/newview/llappviewer.cpp @@ -1548,7 +1548,6 @@ bool LLAppViewer::doFrame() { S32 non_interactive_ms_sleep_time = 100; LLAppViewer::getTextureCache()->pause(); - LLAppViewer::getImageDecodeThread()->pause(); ms_sleep(non_interactive_ms_sleep_time); } @@ -1568,7 +1567,6 @@ bool LLAppViewer::doFrame() ms_sleep(milliseconds_to_sleep); // also pause worker threads during this wait period LLAppViewer::getTextureCache()->pause(); - LLAppViewer::getImageDecodeThread()->pause(); } } @@ -1617,7 +1615,6 @@ bool LLAppViewer::doFrame() { LL_PROFILE_ZONE_NAMED_CATEGORY_APP( "df getTextureCache" ) LLAppViewer::getTextureCache()->pause(); - LLAppViewer::getImageDecodeThread()->pause(); LLAppViewer::getTextureFetch()->pause(); } if(!total_io_pending) //pause file threads if nothing to process. @@ -2051,10 +2048,10 @@ bool LLAppViewer::cleanup() sTextureCache->shutdown(); sImageDecodeThread->shutdown(); sPurgeDiskCacheThread->shutdown(); - if (mGeneralThreadPool) - { - mGeneralThreadPool->close(); - } + if (mGeneralThreadPool) + { + mGeneralThreadPool->close(); + } sTextureFetch->shutDownTextureCacheThread() ; sTextureFetch->shutDownImageDecodeThread() ; -- cgit v1.2.3
