2015-04-01SourceLevelDebugPkg: Use CPU Local APIC timer to handle timeout.Jeff Fan
Use CPU Local APIC timer to handle timeout when read data from debug port, instead of the TimerLib in Debug Communication lib instances. It could remove much duplicated code in Debug Communication Lib instances.

2013-01-25This revision can only work with Intel(c) UDK Debugger Tool version 1.3 or ↵vanjeff
greater. Detailed change log is as below: 1. Add DebugAgentPei driver to initialize Debug Agent in PEI phase. Add DebugAgentDxe driver to initialize Debug Agent in DXE phase. DebugAgentDxe driver could be loaded and unloaded in shell. 2. Update the SourceLevelDebugPkg so that the debug agent can be initialized in any phase: SEC, PEI or DXE. 3. Add an enhanced retry algorithm that provides a robust connection when data loss happens in the debug channel. 4. Clear DR7 register in exception handler. 5. Set the default serial port parameter to 0 instead of PCDs. 6. Build pointer of Mailbox in HOB instead of Mailbox itself, since HOB may be moved at DXE entry point function. 7. Raise TPL to prevent recursion from EFI timer interrupts in SerialIo.c. 8. Add one spin lock for accessing Mailbox when MP debugging supported. 9. Use more non-NULL library instances in SourceLevelDebugPkg DSC file, thus DebugAgentDxe.efi built from SourceLevelDebugPkg could work in shell. 10.Separate all operations about IDT table entry from SecDebugAgentLib.c into DebugAgent\DebugAgentCommon's arch sub-directory. 11.Enhance Debug Agent to avoid breaking by hardware SMI during DXE debugging phase. 12.Add supporting on mode switch code debugging. 13.Remove reset Host Controller operation in DebugCommunicationLibUsb.c to avoid impacting EDKII usb stack. 14.Fix debug timer interrupt missing issue after back from legacy code.

2012-06-11This revision can only work with Intel(c) UDK Debugger Tool version 1.2 or ↵vanjeff
greater. Detailed change log is as below: 1. Define the transfer protocol revision mechanism. Increase the revision number to 0.2 and inform user to use the latest one when the HOST software is too old. New HOST software will implement logic to handle all other revision mismatch cases. 2. Define new debug message packet to print the debug agent trace information by debug port channel. 3. Add check sum mechanism in the communication protocol between TARGET/HOST. 4. Introduced one "try" mechanism to avoid Debug Agent crashed by some invalid HOST command. 5. Enable the late-attach feature: Change the break in from "!" to "\xFC". Add a new short symbol "\xFA" for attach and a new debug command for detach. 6. Support Terminal work on debug port by install EFI Serial IO protocol upon Debug Communication Library. 7. Enable CPUID feature. 8. Enable the hardware data breakpoint. 9. add handshake to improve usb debug cable identify stability issue. 10.Refine all the communication protocol packet to improve extensibility and debugging performance. a. Use 64bit for IO port address. b. Add additional Width field to READ_MEMORY/WRITE_MEMORY. c. Add SEARCH_SIGNATURE support to speed the symbol finding for late attach. d. Remove READ_GROUP register. e. Add READ_ALL_REGISTERS support (WinDbg always requests to read all registers). 11.Move AcquireDebugPortControl () in advance to fix resource collision on IpiSentByApFlag. 12.Fix IO break point does not work issue in PEI phase. 13.Avoid BSP/APs collision when they met break point at the same time. 14.Solve a bug of calculating debug handle in sec phase. 15.Use mailbox content at Dxe phase but not clear it and reinitialize again. 16.Fix FP/MMX/XMM/IO/MSR access issue in both Gdb and WinDbg.
