2015-06-08SourceLevelDebugPkg/DebugAgent: Disable Debug Timer as earlyJeff Fan
InitializeApicTimer() will enable Local APIC timer interrupt. 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.

2015-05-18SourceLevelDebugPkg: Fix Serial Port connection cannot be setupRuiyu Ni
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.

2015-01-20Use RLE (Run Length Encoding) to improve debugging performance.Ruiyu Ni
DEBUG_AGENT_REVISION is DEBUG_AGENT_REVISION_03 to disable this feature and will be changed to DEBUG_AGENT_REVISION_04 when new version of HOST is released. Reduce the stack usage by re-using the same buffer to send/receive packet. Zero out the buffer before fxsave so that the reserved field in the buffer remains 0 for better RLE compression ratio.

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.

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.
