svn path=/trunk/; revision=45278
 2010-01-27 00:06:48 +00:00
Sir Richard 49ca1be9f3 [HAL]: Implement the profile and clock interrupt trap/handlers in C instead of ASM. This allows the kernel to remove the ugly hacks based on internal knowledge of how the assembly/stack of the HAL is supposed to look like. Everything is now done through a clean C interface. 
[NTOS]: Remove said hacks and have a normal C implementation of KeUpdateSystemTime. It exits the interrupt through a soft interrupt exit.
[NTOS]: Implement 4 lines of support code needed to handle interrupts during V8086 mode, which were lacking since we weren't hitting this case yet.
Note that now the KeUpdateSystemTime interface is not "compatible" with Windows anymore. This does not matter, since the only possible caller of KeUpdateSystemTime is a very specific HAL routine that needs a very specific stack layout to actually work, so the chance of anyone calling this API is absolutely zero (no, not even some experimental driver. It's absolutely impossible).

Sir Richard 92df9a6434 [HAL]: Rewrite all V8086-related code in C instead of ASM. Delete v86.s. Makes uses of new macros and developments in NTOS, but should now only end up getting called at shutdown and for bugchecks.

Sir Richard 842d2aa5f9 [PERF]: What to do when your SYSEXIT code has a bug? Set KiFastSystemCallDisable to TRUE so it never gets used. Now, for the first time in 3 years and 3 months (not giving a specific revision # to protect the 'innocent'), ReactOS actually fully uses the SYSENTER/SYSEXIT instructions isntead of IRETD, since my code doesn't exhibit the bug and SYSEXIT is safe to use. This should save a good hundred cycles or more per system call.

Sir Richard dd14b916ff [PERF]: After spending the better part of the last two days rewriting the HAL V8086 code (used for BIOS Display Reset) in C, it dawned upon me that it shouldn't even be used during bootup in the first place! The boot loader, running in real-mode, already sets video mode 12 when starting ReactOS. We then repeat the operation, but since we're in protected mode, we have to emulate the whole sheebang with V8086 mode. We now initialize bootvid without requesting a mode switch (which was broken up until a commit ago). This gives us a dirty palette and VGA state. We then call VidResetDisplay to clean up the palette and setup the VGA registers correctly, but we only reset the screen if a custom /BOOTLOGO command is used (which isn't supported yet). We therefore don't need to enter V8086 mode at all up until the switch to graphics mode from the video card driver. Note that Windows doesn't do this (Win7 might due to the new Boot Graphics Library), so we're actually booting faster!

Sir Richard 590b4a4093 [BOOTVID]: Fix completely broken VidInitialize routine. I have no idea what the original code was trying to accomplish.

Sir Richard 71162a52f5 [NTOS]: Refactor some stub code and add a couple of more possible trap exit mechanisms (needed for HAL). Later we should really combine all the exit macros into one, as we've done for the entry macro. 
svn path=/trunk/; revision=45268
 2010-01-26 17:54:50 +00:00
Sir Richard 66a3a56604 [HAL]: Move the HalpApcInterrupt and HalpDispatchInterrupt to pic.c now that there is a C-macro to generate such stubs. Remove irq.S from build/sources. 
svn path=/trunk/; revision=45267
 2010-01-26 16:31:32 +00:00
Sir Richard 12a31f1df7 [NTOS]: Implement a C/Extended ASM macro for generating trap stubs, removing the need to do this in ASM. The macro covers all possible entries, from SYSENTER to a fake sotware interrupt (needed for HAL changes later). By being somewhat in C, it makes the code cleaner to read and uses C expressions to make its decisions, making the code more maintanable as well. It also removes the need for separate assembly files. 
[NTOS]: Modify the semantics of how a fast system call (SYSENTER) is processed in the stub, by moving more work in the C handler, such as setting up FS and getting the correct argument stack. Saves us some cycles too (and allows the trap stub macro to be more generic).

 2010-01-26 10:23:30 +00:00
Sir Richard 219e108e3c [NTOS]: Split the GENERATE_TRAP_HANDLER in two separate macros. The original builds the name of the function (and makes it global), while the TRAP_HANDLER_PROLOG is actually the code. 
[NTOS]: Make TRAP_HANDLER_PROLOG handle software traps, in which the interrupt stack must be faked.
[NTOS]: Optimize TRAP_HANDLER_PROLOG by not pushing an error code and then making space on the stack without the error code -- just make space with the error code in the first place (nobody reads the value, so having it zero or garbage isn't important).
[HAL]:  Implement the APC and DPC software interrupt traps in C instead of ASM. Delete all contents of irq.S except the two GENERATE_TRAP_HANDLER stubs.

Sir Richard 44b79bf92f You really need to get your compiler version shit together. I was told GCC 4.4 is what's used in ReactOS, yet the build server insists on using an old and broken version of GCC that doesn't support half the things we're trying to do here! Hackfix the Mask Table by providing ugly and incomprehensible hex magic numbers for the mappings, if a GCC older than 4.4 is used.

Sir Richard b4d77b18a8 [PERF]: Make the trap entry/exit macros inlined, just as they used to be before in their pure-assembly forms. This should boost performance quite a bit by avoiding 2-3 extra calls during traps and system calls. 
[NTOS]: Cleanup the traphdlr.c vs. trap_x.h mess into something much more structured. trap_x.h is now all inlined C functions which pretty much replace the asmmacros.S file. It is meant to be used outside the kernel as well (such as by the HAL, which requires trap entry/exit too).
[PERF]: Give UNREACHABLE another try, this time with GCC 4.5+, 4.4+, 4.4- and MSVC support.
[PERF]: Remove ABIOS checks since ReactOS does not support this, and since it doesn't look like the target kernel actually does either, we can remove this vestigal/unsupported code, saving some extra branches and checks.

Sir Richard 280c5bef1e [PERF]: Make all trap handlers, trap exit code, fatal exit code, and exception dispatch code "no return" since it always leads to an iret or other kind of non-directly-returning mechanism. This allows the compiler to optimize better and also remove useless code at the bottom of the functions. Since __builtin_unreachable is only for GCC 4.5, we use exit(0) for now (it will never be reached) to trick GCC.

Sir Richard cdb563f380 [PERF]: Replace early ZwClose system calls with ObCloseHandle(KernelMode). This avoids taking a system call for those cases and gives a slight perf boost to booting up the system. It also pushes the first system call somewhat later in the boot process, allowing for easier debugging should the interface have issues/need tracing. 
[NTOS]: Do not attempt querying the Registry Primary Handle for the Backing Hive File Size in the case where there is no actual Primary! There was no error checking so nobody noticed this happens -- it also probably resets Cluster to 0 (instead of 1), which can cause corruption in some cases.
[NTOS]: Make KiUserTrap use the MODE_MASK instead of hard-coding a check for Ring 0 CS (which is slower and not as correct).

Sir Richard 0cae32e094 [NTOS]: Export the C KiEoiHelper alongside the ASM Ke386EoiHelper. Yes, this is a "ReactOS-only" export, but really this interface is reserved for the HAL, and as long as we keep Ke386EoiHelper, the NT HAL should still work. 
Need to revisit/finalize this decision and whether or not we can emulate the C-interface with Ke386EoiHelper somehow (reliably).

Sir Richard e18680bb11 [NTOS]: KiDispatchInterrupt crushes EBX, so maybe it should preserve it first? This only worked because KiDispatchInterrupt was only called by ASM code that already was magically aware of this fact, and preserved (or didn't use) EBX before making the call. Yuck!

Sir Richard c030074001 [PERF]: Do not declare the PCR in KeGetPcr as volatile. It is only volatile as in "if there is a context switch, the PCR is different". You are in a LOT of trouble if the thread switches while your code is running in the first place, and your code is somehow running as a different thread! 
This change makes C code a lot neater, especially during PCR access, because it doesn't force reloading the PCR each time. For example, Read-Modify-Operations on the PCR, such as AND are 1 line of assembly instead of 3.
This helps and will help further with the C HAL, as well as the C trap handlers.
