Kudzu

• Stop debugging
  • EngineUtils.cs - line 74
• Complete X# Port
  • Remove old X# CodeGroup
  • Remove old X# translator
  • use includes for compiling nasm
  • PreserveRegisters
  • AL = ComRead8()
  • ComWrite(AL)
• Plugs
  • Allow plug attrib to specify asm name and link to X# directly.
• Simplify assembler - methods and straight to text/bin. Current system is overly complicated
  • Also skip c# step - compile straight to .asm from X#
• return errors when comport cant open
• OutputDebug Catcher with filters, categories, timestamps
• X# Code Completion
• Asm stepping
  • Historical panels
• Convert cxdb to sql compact and edm
  • http://www.microsoft.com/download/en/details.aspx?id=17876
• Increase speed of DebugStub / lower impact
• DS Ping or set a breakpoint while not in a break state will hang VS.
  • This is because its waiting on some other command to release?
• Watches
  • Memory watches
  • this:28 - show its size
  • watches - show EBP+-
  • frame - show var names
  • asm window - show values of EBP, etc...
• watches that can see fields/members
  • of other classes besides this
• ATA / FAT
• ring restrictions on console etc.. by class, or explict inclusion
• PIT/RTC
  • And sleep, needed for ATA
• tohex plug based on string input of X8 etc
• Bootstrap - clean up more
• networking
• gc
• USB

debugstub.SkipMethod
SkipClass
speedup debug stub on no trigger
compiler dynamic load
unsafe arrays but controllled

Matthijs - Next Release

• Express isnt showing any templates - VB only?
• C# for menus
• Debug VS on Cosmos menu

Trivalik - Next Release

• Remove 2008
  • And 2010 suffixes

 Next Release + 1

• Throw exception on null ref...
• Plugs - warn if plugging something that doesnt exists... caused the x08 bug?
• (joint with Kudzu) - Move all critical plugs out of old asms and remove building of old asms.
  • And the plugs also from CustomImplementations in IL2CPU?
• Exceptions dont work. Try int.parse("asdf"). It runs but when the exception is hit we get garbage back instead. (ie exceptions through plug proxy dont work)
• IL2CPU.AlwaysCompile attribute and get rid of IDT.Dummy
• int j = Array.IndexOf(Digits, s[i]);
  • When Digits is a char array, we get a plug needed error.
• cxdb contains full asm path and filenames over and over... cant we write them out once and use a byte/word index to identify them? This will make it smaller and make reading faster.
• Plugs
  • Source Plugs - Leave as they are
  • Assembly Plugs - Change to have attribute on the TARGET instead of the implementation and only allow assembly.. this cuts out the "proxy" class and makes it easier to find plug impls. See Rings.html for more info. The assembly level plugs can even go in the same assembly, source file and if we can the same class? That is currently these assembly plugs require 3 classes to implement. its ugly and messy... we can get it down to 2 - 1 + assembly (X# only!). Current way is such a mess we even comment them as plugged, but then have to go guessing where the impl is... See example down below....
  • Convert all source plugs and disable old attributes...so for new ones use new names
• We need to dynamically load the plugs etc so we can just rebuild and run and even trace them without rerunnig the bat for each change
• Ring attributes and enforcement
  • Also allow restriction of assembly references
  • Only allow core to be /unsafe, no others

Even later

• localloc - int.parse needs plug for now because of this.
• Filesystem
• Memory Manager
  • http://www.osdever.net/tutorials/view/memory-management-1
  • http://www.osdever.net/tutorials/view/memory-management-2
• UDP
• TCP
• Cosmos.Debug.Common - much in here is not common and should be moved to VSDebug.. Add  Readme.html that NASM and VSDebug use whats left
• foreach / interfaces

Further Down

• USB

Assembly Plug Example

Old way

(3 classes, often 3 source files as well)

public class CPUBus {
	// Plugged
	public static void Write8(UInt16 aPort, byte aData) { }
...

[Plug(Target = typeof(Cosmos.Kernel.CPUBus))]
class CPUBus { 
	[PlugMethod(Assembler = typeof(Assemblers.IOWrite8))]
	public static void Write8(UInt16 aPort, byte aData) { }
...

public sealed class IOWrite8: AssemblerMethod { 
	public override void AssembleNew(object aAssembler, object aMethodInfo) { 
		//TODO: This is a lot of work to write to a single port. We need to have some kind of inline ASM option that can emit a single out instruction 
		new CPUx86.Move { DestinationReg = CPUx86.Registers.EDX, SourceReg = CPUx86.Registers.EBP, SourceDisplacement = 0xC, SourceIsIndirect = true };
		new CPUx86.Move { DestinationReg = CPUx86.Registers.EAX, SourceReg = CPUx86.Registers.EBP, SourceDisplacement = 0x8, SourceIsIndirect = true };
		new CPUx86.Out { DestinationReg = CPUx86.Registers.AL }; 
	}
} 

New way

See how much neater and self contained this is? :)

public class CPUBus {
   
    [AsmBody(Assembler = typeof(IOWrite8))]
    public static void Write8(UInt16 aPort, byte aData) { }
    // Nested class even... :) Keeps it all in one unit!
    public class IOWrite8 : CodeBlock {
        public override void Assemble() {
            EDX = EBP + 0x0C;
            EAX = EBP + 0x08;
            Port[DX] = AL;
        }
    }

}
