From 0bb5d7a55b7f3537b9e89f1b135993412fe343c5 Mon Sep 17 00:00:00 2001 From: "Brian J. Johnson" Date: Fri, 3 Jul 2015 02:29:01 +0000 Subject: [PATCH] SourceLevelDebugPkg: Fix PEI debug timer regression Recent changes to debug timer handling ended up leaving the timer disabled in PEI. This made it impossible to stop execution in PEI externally via the debugger. Enable the timer when InitializeDebugAgent calls InitializeDebugAgentPhase2, as well as when it returns directly.
