X-Git-Tag: edk2-stable201903~16148 X-Git-Url: https://git.proxmox.com/?p=mirror_edk2.git;a=commitdiff_plain;h=6a429dfa5fcecc96d36828e922d6bfe6322f33a0;hp=233af82b524d8807906bc314b1f09b1199562bec Change back the TPL of PCD from TPL_CALLBACK to TPL_NOTIFY because the following issue is found: When we manually connect a device path mapping to the serial terminal with non-default band rate, the SerialIo driver would Reinstall its device path protocol eventually causing ConSplitter::DriverBindingStart() to run and finally would call PcdGet32 (PcdConOutColumn) in ConsplitterSetConsoleOutMode(). Since SerialIo driver raises TPL to TPL_NOTIFY initially, the call to PcdGet32 would cause TPL assertion if TPL of PCD is TPL_CALLBACK. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10188 6f19259b-4bc3-4df7-8a09-765794883524 --- diff --git a/MdeModulePkg/Universal/PCD/Dxe/Pcd.c b/MdeModulePkg/Universal/PCD/Dxe/Pcd.c index c1e4117f49..363a949ea5 100644 --- a/MdeModulePkg/Universal/PCD/Dxe/Pcd.c +++ b/MdeModulePkg/Universal/PCD/Dxe/Pcd.c @@ -26,7 +26,7 @@ EFI_GUID *TmpTokenSpaceBuffer[PEI_EXMAPPING_TABLE_SIZE + DXE_EXMAPPING_TABLE_SIZ /// /// PCD database lock. /// -EFI_LOCK mPcdDatabaseLock = EFI_INITIALIZE_LOCK_VARIABLE(TPL_CALLBACK); +EFI_LOCK mPcdDatabaseLock = EFI_INITIALIZE_LOCK_VARIABLE(TPL_NOTIFY); /// /// PCD_PROTOCOL the EDKII native implementation which support dynamic
