* SourceLevelDebugPkg DebugCommUsb3: Return error when debug cap is resetStar Zeng2018-03-211-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When source level debug is enabled, but debug cable is not connected, XhcResetHC() in XhciReg.c will reset the host controller, the debug capability registers will be also reset. After the code in InitializeUsbDebugHardware() sets DCE bit and LSE bit to "1" in DCCTRL, there will be DMA on 0 (the value of some debug capability registers for data transfer is 0) address buffer, fault info like below will appear when IOMMU based on VTd is enabled.

* SourceLevelDebugPkg DebugUsb3: Re-Support IOMMUStar Zeng2018-03-156-112/+954
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | de8373fa07f87ca735139bb86c51e2c29fb1d956 could not handle two cases. 1. For the case that the USB3 debug port instance and DMA buffers are from PEI HOB with IOMMU enabled, it was to reallocate the DMA buffers by AllocateAddress with the memory type accessible by SMM environment. But reallocating the DMA buffers by AllocateAddress may fail. 2. At S3 resume, after the code is transferred to PiSmmCpuDxeSmm from S3Resume2Pei, HOB is still needed to be used for DMA operation, but PiSmmCpuDxeSmm has no way to get the HOB at S3 resume. The patch is to re-support IOMMU. For PEI, allocate granted DMA buffer from IOMMU PPI, register IOMMU PPI notification to reinitialize hardware with granted DMA buffer if IOMMU PPI is not present yet. For DXE, map DMA buffer by PciIo in PciIo notification for early DXE, and register DxeSmmReadyToLock notification to reinitialize hardware with granted DXE DMA buffer accessible by SMM environment for late DXE. DebugAgentLib has been managing the instance as Handle in HOB/SystemTable. The Handle(instance) from DebugAgentLib can be used directly in DebugCommunicationLibUsb3. Then DebugCommunicationLibUsb3 could get consistent Handle(instance) from DebugAgentLib.

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.

This commit introduces a Pcd to reflect the revision in order to avoid the comparison of two macros, which will generate a constant result detected by code checkers.

* 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.
