From 9f82a9a2444a232e746992fa89084b928255cb63 Mon Sep 17 00:00:00 2001 From: FearlessTobi Date: Wed, 20 May 2020 21:28:16 +0200 Subject: crypto: Make KeyManager a singleton class Previously, we were reading the keys everytime a KeyManager object was created, causing yuzu to reread the keys file multiple hundreds of times when loading the game list. With this change, it is only loaded once. On my system, this decreased game list loading times by a factor of 20. --- src/core/file_sys/bis_factory.cpp | 2 +- src/core/file_sys/card_image.cpp | 4 ++-- src/core/file_sys/card_image.h | 2 +- src/core/file_sys/content_archive.cpp | 5 ++--- src/core/file_sys/content_archive.h | 5 ++--- src/core/file_sys/registered_cache.cpp | 6 +++--- src/core/file_sys/registered_cache.h | 2 +- src/core/file_sys/submission_package.cpp | 4 ++-- src/core/file_sys/submission_package.h | 2 +- src/core/file_sys/xts_archive.h | 2 +- 10 files changed, 16 insertions(+), 18 deletions(-) (limited to 'src/core/file_sys') diff --git a/src/core/file_sys/bis_factory.cpp b/src/core/file_sys/bis_factory.cpp index 0af44f340..464ca6503 100644 --- a/src/core/file_sys/bis_factory.cpp +++ b/src/core/file_sys/bis_factory.cpp @@ -79,7 +79,7 @@ VirtualDir BISFactory::OpenPartition(BisPartitionId id) const { } VirtualFile BISFactory::OpenPartitionStorage(BisPartitionId id) const { - Core::Crypto::KeyManager keys;
