Resend this patch again. This patch renames the duplicated function name to fix it. The SecPeiDebugAgentLib uses the global variable mMemoryDiscoveredNotifyList for a PPI notification on the Memory Discovered PPI. This same variable name is used in the DxeIplPeim for the same PPI notification. The XCODE5 tool chain detects this duplicate symbol when the OVMF platform is built with the flag -D SOURCE_DEBUG_ENABLE. The fix is to rename this global variable in the SecPeiDebugAgentLib library.

* SourceLevelDebugPkg: Refine casting expression result to bigger sizeHao Wu2017-03-064-19/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are cases that the operands of an expression are all with rank less than UINT64/INT64 and the result of the expression is explicitly cast to UINT64/INT64 to fit the target size. An example will be: UINT32 a,b; // a and b can be any unsigned int type with rank less than UINT64, like // UINT8, UINT16, etc. UINT64 c; c = (UINT64) (a + b); Some static code checkers may warn that the expression result might overflow within the rank of "int" (integer promotions) and the result is then cast to a bigger size. The commit refines codes by the following rules: 1). When the expression is possible to overflow the range of unsigned int/ int: c = (UINT64)a + b; 2). When the expression will not overflow within the rank of "int", remove the explicit type casts: c = a + b; 3). When the expression will be cast to pointer of possible greater size: UINT32 a,b; VOID *c; c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b); 4). When one side of a comparison expression contains only operands with rank less than UINT32: UINT8 a; UINT16 b; UINTN c; if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...} For rule 4), if we remove the 'UINTN' type cast like: if (a + b > c) {...} The VS compiler will complain with warning C4018 (signed/unsigned mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

* SourceLevelDebugPkg: Fix PEI timer interrupt regressionBrian J. Johnson2015-07-091-2/+4
| | | | | | | | | | | | | | | | | | | | | | | Recent changes to debug timer initialization (commit 2befbc82, svn 17572) modified the Sec/Pei InitializeDebugAgent() routine to enable debug timer interrupts. This causes problems in the DEBUG_AGENT_INIT_POSTMEM_SEC case: the callers appear to assume that if they block timer interrupts before the call, interrupts will remain blocked afterwards. It is not always safe to have interrupts enabled on return from InitializeDebugAgent(). For instance, after calling InitializeDebugAgent(), OvmfPkg's TemporaryRamMigration() moves the stack, heap, and IDT to RAM, then switches to the new stack. Only then does it reenable timer interrupts. Taking an interrupt during this process can corrupt state, causing crashes. Do not unmask the debug timer interrupt in the DEBUG_AGENT_INIT_POSTMEM_SEC case. Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Brian J.

Even though we disable CPU interrupt at the beginning and enable CPU Interrupt after debug agent initialized completely, some Boot Service may invoke RestoreTpl () which may enable CPU interrupt. We should disable Local APIC timer in InitializeDebugTimer () to avoid Debug Timer interrupt happens during debug port and debug agent initialization phase. And enable Debug Timer interrupt after debug agent is initialized.

| | | | | | | | | | | | | Now Debug Agent library uses Local APIC Timer to implement time-out mechanism. In SMM, SMM BSP maybe not be the one in DXE phase, its local APIC timer may not work. This fix is to initialize Local APIC timer if it doesn't work as expected at SMM entry.

| | | | | | | | | | | The root cause is SerialPortDebugCommunicationLib returns NULL debug port handle causing the CompressData() doesn't send the compressed data. The fix doesn't rely on the debug port handle value and uses Send parameter to indicate whether to send the compressed data.
