- Disable the MiCacheImageSymbols call in MmLoadSystemImage for KD too as this hack is required for rossym rather than KDBG. Fixes detection of non-boot driver images by WinDbg. - Add another hack to freeldr.c to make sure that HAL is the second entry in the Load Order list -- detect if it isn't and insert it as the second entry manually if it isn't. - KdbInitialize can now assume that the 2nd entry in the Load Order list is HAL, just like ExpLoadBootSymbols and KD does, so get the Loader Entry directly instead of searching for it. - Move KiBootTss and KiBootGdt to freeldr.c as this is where they belong -- they are not required for NTLDR/WINLDR boot style and are only used directly in freeldr.c. - Get rid of the AcpiTableDetected variable from freeldr.c. Instead, set the AcpiTable entry to something and make PoInitSystem check for that instead to preserve the old behavior. - Implement KdpGetFirstParameter and KdpGetSecondParameter for ARM too -- just retrieve R3/R4 here. Also rename those macros to clarify what parameters we are retrieving. - Add MmIsSessionAddress stub and use it from KD handle session space properly in the Memory Query API, and ASSERT that we are not trying to do a copy to/from session space in MmDbgCopyMemory as we don't handle it properly. Put this in mmdbg.c for now as we don't implement session space, and it is only called from KD right now. - Rename the 3 kdsup.c files to kdx86.c, kdx64.c and kdarm.c to differ them from each other. - Implement KdpAllowDisable -- just check if any processor breakpoints are set on any processor in the system and disallow the disable if so. The routine is now architecture dependant, so move it to the appropriate files. - Get rid of the MmFreeLdr* variables too. These have been deprecated for some time now. - The ModuleObject and ImageBaseAddress parameters of MmLoadSystemImage are not optional so don't treat them as such, and don't zero initialize them as callers shouldn't rely on this. - Set LDRP_ENTRY_NATIVE instead of LDRP_COMPAT_DATABASE_PROCESSED to mark the image as a native image. Also fix the value of LDRP_ENTRY_NATIVE. - Fix definition of LDR_DATA_TABLE_ENTRY -- the Checksum member should be in the union too. - Remove some unnecessary externs for stuff we now define globally in the kernel headers. - Rename some variables in KD to better match the logic. - Move some x86 only stuff from global ke.h and ke_x.h to the x86 dependent ke.h. Remove DR_ACTIVE_MASK as it has been deprecated/unused for a while now. svn path=/trunk/; revision=44023

Mega KD64 revival patch: KD64 - Fix some 64-bit issues and some x86 specificness. - Sub out some KdpTrap cases more properly. - Implement support for .crash and .reboot. Does not seem to work currently because of weird issues. - Implement KdpDprintf to send strings directly to the debugger from inside of KD64. Use it in KdEnterDebugger instead of DbgPrint so we won't try to enter the debugger recursively. - Implement KdUpdateDataBlock to set the KeUserCallbackDispatcher pointer in the debugger block after its address is retrieved from ntdll. - Don't assume breakpoints are 1 byte long in portable code -- use KD_BREAKPOINT_SIZE and define it per architecture. - KdpStub: KdEnableDebugger returns NTSTATUS, not TRUE/FALSE. Other - wdbgexts.h: Properly define CURRENT_KD_SECONDARY_VERSION for AMD64. - Make PsNtosImageBase pointer-sized as it should be. - Change the definition of KDSTATUS so it is guaranteed to be 32-bit. - Fix a critical bug in KiRestoreProcessorControlState: it didn't clear the busy flag in the TSS before reloading the task register, resulting in a GPF if we tried to reload the same register. - Add macros for getting and setting special purpose registers (the Program Counter and the "return register") in portable code instead of using #ifdef every time. Do likewise for setting IMAGE_FILE_MACHINE_XXX, using a new IMAGE_FILE_MACHINE_ARCHITECTURE macro. - Don't refer to the Program Counter as "Eip" in portable code. - Define DBG_STATUS_CONTROL_C for assembly code and use it in KeUpdateSystemTime. svn path=/trunk/; revision=43283

Mega KD64 revival patch: KD64 - Fix some 64-bit issues and some x86 specificness. - Sub out some KdpTrap cases more properly. - Implement support for .crash and .reboot. Does not seem to work currently because of weird issues. - Implement KdpDprintf to send strings directly to the debugger from inside of KD64. Use it in KdEnterDebugger instead of DbgPrint so we won't try to enter the debugger recursively. - Implement KdUpdateDataBlock to set the KeUserCallbackDispatcher pointer in the debugger block after its address is retrieved from ntdll. - Don't assume breakpoints are 1 byte long in portable code -- use KD_BREAKPOINT_SIZE and define it per architecture. - KdpStub: KdEnableDebugger returns NTSTATUS, not TRUE/FALSE. Other - wdbgexts.h: Properly define CURRENT_KD_SECONDARY_VERSION for AMD64. - Make PsNtosImageBase pointer-sized as it should be. - Change the definition of KDSTATUS so it is guaranteed to be 32-bit. - Fix a critical bug in KiRestoreProcessorControlState: it didn't clear the busy flag in the TSS before reloading the task register, resulting in a GPF if we tried to reload the same register. - Add macros for getting and setting special purpose registers (the Program Counter and the "return register") in portable code instead of using #ifdef every time. Do likewise for setting IMAGE_FILE_MACHINE_XXX, using a new IMAGE_FILE_MACHINE_ARCHITECTURE macro. - Don't refer to the Program Counter as "Eip" in portable code. - Define DBG_STATUS_CONTROL_C for assembly code and use it in KeUpdateSystemTime. svn path=/trunk/; revision=43283

// All VDM/V8086 opcode emulators have the same FASTCALL function definition.
// We need to keep 2 parameters while the original ASM implementation uses 4:
// TrapFrame, PrefixFlags, Eip, InstructionSize;
//
// We pass the trap frame, and prefix flags, in our two parameters.
//
// We then realize that since the smallest prefix flag is 0x100, this gives us
// a count of up to 0xFF. So we OR in the instruction size with the prefix flags
//
// We further realize that we always have access to EIP from the trap frame, and
// that if we want the *current instruction* EIP, we simply have to add the
// instruction size *MINUS ONE*, and that gives us the EIP we should be looking
// at now, so we don't need to use the stack to push this parameter.
//
// We actually only care about the *current instruction* EIP in one location,
// so although it may be slightly more expensive to re-calculate the EIP one
// more time, this way we don't redefine ALL opcode handlers to have 3 parameters,
// which would be forcing stack usage in all other scenarios.

- Implement support for reading and writing physical memory for KD. The implementation uses a reserved mapping page to map the target physical address to. On x86 this page is located at virtual address 0xFFBFF000, and the PTE for this page is the last PTE of the nonpaged pool's PDE. Other architectures may need to reserve the PTE elsewhere. - The physical memory support relies on several Mm variables and structures to be properly set up. Add a new flag, MiDbgReadyForPhysical, and set it when the debugger support can handle physical memory requests. - Protect this page with a Memory Area to make the old Mm keep its dirty hands off it. - Does not support I/O space or cache flags yet. - Add generic KeInvalidateTlbEntry to invalidate a single TLB entry for a given address instead of flushing the whole TLB. Used by the debugger physical memory support as invalidating the whole TLB for every map and unmap of its debug PTE would incur significant overhead for large copies. Replace direct usage of __invlpg() with this in x86 code too. - Fix incorrect cache flag check and set in KdpRead/WritePhysicalmemory for write combined requests. The debugger's Uncached flag was checked instead of the Write Combined flag, and the debuggers Write Combine number (0x3) was set instead of Mm's flag (0x20). - Fix implementation of MmIsAddressValid (at least for x86; other architectures will need more checks). Just check the Address' PDE and PTE valid bits instead of using Memory Areas. - Add missing ASSERTs to ensure the Memory Areas for paged pool, the PCR page, and the Shared User Data page are created. - Add missing Memory Area for the 2 pages HAL currently uses for its own mappings on x86 -- previously, those pages could have been allocated by other parts of the OS, which would have resulted in serious corruptions. svn path=/trunk/; revision=43960

- Disable the MiCacheImageSymbols call in MmLoadSystemImage for KD too as this hack is required for rossym rather than KDBG. Fixes detection of non-boot driver images by WinDbg. - Add another hack to freeldr.c to make sure that HAL is the second entry in the Load Order list -- detect if it isn't and insert it as the second entry manually if it isn't. - KdbInitialize can now assume that the 2nd entry in the Load Order list is HAL, just like ExpLoadBootSymbols and KD does, so get the Loader Entry directly instead of searching for it. - Move KiBootTss and KiBootGdt to freeldr.c as this is where they belong -- they are not required for NTLDR/WINLDR boot style and are only used directly in freeldr.c. - Get rid of the AcpiTableDetected variable from freeldr.c. Instead, set the AcpiTable entry to something and make PoInitSystem check for that instead to preserve the old behavior. - Implement KdpGetFirstParameter and KdpGetSecondParameter for ARM too -- just retrieve R3/R4 here. Also rename those macros to clarify what parameters we are retrieving. - Add MmIsSessionAddress stub and use it from KD handle session space properly in the Memory Query API, and ASSERT that we are not trying to do a copy to/from session space in MmDbgCopyMemory as we don't handle it properly. Put this in mmdbg.c for now as we don't implement session space, and it is only called from KD right now. - Rename the 3 kdsup.c files to kdx86.c, kdx64.c and kdarm.c to differ them from each other. - Implement KdpAllowDisable -- just check if any processor breakpoints are set on any processor in the system and disallow the disable if so. The routine is now architecture dependant, so move it to the appropriate files. - Get rid of the MmFreeLdr* variables too. These have been deprecated for some time now. - The ModuleObject and ImageBaseAddress parameters of MmLoadSystemImage are not optional so don't treat them as such, and don't zero initialize them as callers shouldn't rely on this. - Set LDRP_ENTRY_NATIVE instead of LDRP_COMPAT_DATABASE_PROCESSED to mark the image as a native image. Also fix the value of LDRP_ENTRY_NATIVE. - Fix definition of LDR_DATA_TABLE_ENTRY -- the Checksum member should be in the union too. - Remove some unnecessary externs for stuff we now define globally in the kernel headers. - Rename some variables in KD to better match the logic. - Move some x86 only stuff from global ke.h and ke_x.h to the x86 dependent ke.h.

Patch that fixes VMWare boot (and should fix QEMu/KVM boot on the testbot): [NTOS]: A trap can get us into a state where DS/ES are invalid, making any pointer dereference (on DS/ES segmented memory, not SS, the stack) crash (and probably double-fault). Therefore, we have to be careful to switch to a good DS/ES before touching the TrapFrame pointer, which we don't have in ESP like the ASM code, but in a DS/ES-segmented register. For V8086 traps we can switch to the good DS/ES immediately, but for other kinds of traps, we actually need to save the current (bad) segments first. So we save them on the stack now, then switch to the good ones, then store the stack values into the trap frame. This is what happens on a non-optimized (-O0) build. On an optimized build, the segments will end up in registers instead, which is fine too (they'll be direct values). The order of instructions is guaranteed since the segment macros are volatile. [NTOS]: The GPF and Invalid Opcode handlers are performance critical when talking about V8086 traps, because they control the main flow of execution during that mode (GPFs will be issued for any privileged instruction we need to emulate, and invalid opcode might be generated for BOPs). Because of this, we employ a fast entry/exit macro into V8086 mode since we can make certain assumptions. We detect, and use, such scenarios when the V8086 flag is enabled in EFLAGS. However, because we can land in a GPF handler with an invalid DS/ES, as some V8086 code could trample this during BIOS calls for example, we must make sure that we are on a valid DS/ES before dereferencing any pointer. We fixup DS/ES either in KiEnterTrap (for normal entry/exit) or, for V86, in KiEnterV86Trap. Notice the problem: we need to detect which of these to use early on but we can't touch the EFLAGS in the frame because DS/ES could be invalid. Thankfully SS is always guaranteed valid, so stack dereferences are game! We therefore read the EFLAGS here, in assembly, where we can touch ESP as we please. We save this in EDX, which will be used as the second argument for the FASTCALL C trap entry. When we make the fast V86 check, we use the parameter instead of the trap frame, leading us to using the correct trap entry function, which fixes up DS/ES and lets us go on our merry way... [NTOS]: Make appropriate changes to GENERATE_TRAP_HANDLERS macro. [NTOS]: Switch to using well-known NT trap handler names (hex-based, double-zeroed) instead of decimal-based trap handler names which are confusing. [NTOS]: Clean up some debug spew. svn path=/trunk/; revision=45052
