hackbunny: Jul 22, 2007; I haven't been on SA for years but the person who gave me my previous av as a joke felt guilty for doing so and decided to get me a non-shitty av

hackbunny posted:

oh noooo today is tomorrow and I got drunk with coworkers instead and the effortpost will have to wait 😱

who was it who asked about windows driver development again?

I don't even know where to start! but very broadly speaking, windows drivers are dlls, not exes, with all that it entails. you're running on borrowed time, in a process that isn't yours, at the highest possible level of privilege! not the highest possible really, due to the many management modes supported by modern cpus, but you know unless your driver is one of those drivers that can run in user mode - but the general rule under windows is that kernel mode code doesn't call user mode code (with very very very few exceptions), so drivers like storage devices (kernel mode client example: filesystems; memory manager) and network cards (kernel mode client example: tcp/ip) are restricted to kernel mode only. but I digress

anyway. the things are written in C, in a vaguely object oriented way. two huge red flags, i know, but that's how it works! every driver has a sort of vtable, that provides implementations of each of the I/O functions - all kernels I know about, in fact, implement drivers in a very similar way! all device functions are implemented as I/O operations of some kind, and on windows all I/O is asynchronous by default (with optional synchronous shortcuts for the most common operations, like read and write): when you want to call a device, you allocate a request packet (IRP), set the request parameters, send it and wait for a completion notification. windows has a concept of filter devices, where devices can stack on top of one another, each layer adding some functionality (or just sniffing traffic!), and the IRP has a variable sized tail with enough slots to let each device in the stack transform a I/O operation into a different I/O operation, or maybe just add hooks like completion callbacks, to get notified before the originator of the request is. it's all extremely complicated and quite fragile IME! and the fact that C is the only supported language doesn't help at all. what helps is that some driver classes are already implemented by the OS and what you write is not a full fledged driver, but a "minidriver" that only personalizes the behavior of the os-provided driver. some other driver classes are supported by the windows driver framework, which implements all of the tedious, repetitive boilerplate required. did I mention the boilerplate? OH GOD the boilerplate

development now requires visual studio, other than the driver SDK (which used to be called the DDK but I believe it's the WDK now). thank the stars for it, because before it was a godawful makefile-based system, the same godawful makefile-based system that was used to build windows itself, in fact. you need a second machine for debugging, and some sort of cable. in the bad old days, it was a slow AF serial cable, I wonder if USB is supported now? you can use a VM too, of course, if your driver doesn't require some specific hardware

this very bad explanation is as succinct an overview I can give you on windows driver development, whoever it was who asked about it in the first place. even more succinctly: it's bad, don't do it

figuring out how to detect VBLANKs that come in over the CPU's interrupt line

Z80 Interrupt Mode 2 posted:

An interrupt occurs
The CPU will then form a 16-bit address where the I Register is the Most Significant byte and the Least Significant Byte is a number received from the data bus.
A 256 byte vector table must be created in the range of $xx00 to $xxff, where xx is the I register. The 256 bytes cover all possible combinations that can occur by the random value received from the data bus.
Once the 16-bit address is formed, a jump will occur to this vector table. It jumps to an even address and uses two bytes to form another 16-bit address.
Then it performs a jump to this newly created 16-bit address.
Since the jump is basically random in this 256 byte region, all the bytes in the table values will be filled with the same value, for example, $8f. That way a when it jumps to the table it will form a 16-bit address of $8f8f, no matter where it jumps to in this table (which is always an even address), a jump to $8f8f

the device actually triggering the interrupt is supposed to write a particular value. so you can set up an interrupt table and then jump to the handler corresponding to that peripheral.

are you using a particular machine that has badly-behaved peripherals?

it works great. there's a lot of newish features in typescript that make redux really nice. like with type guards i can sort of pattern match off of actions in my reducer. for example:

code:

function actionIsType<PayloadT>(type: string, action: IAction<any>): action is IAction<PayloadT> {
  return action.type === type;
}

function reducer(state: IState = {}, action: IAction<any>): IState {
  if (actionIsType<AnusPayload>("RECEIVED_ASS", action)) {
    // in this block the typechecker knows that `action` is of type `IAction<AnusPayload>`
    return mergeState(state, { sphincter: action.payload.hole }); 
  }
  return state;
}

also because of partial types i can write my utility mergeState with the type: `function mergeState(state: IState, updates: Partial<IState>): IState` so it ensures that the 2nd argument is a subset of my state

the only place i lose type information is in react-redux's connect() function, in the mapDispatchToProps object you pass in. i can probably use one of the alternatives, like the version where mapDispatchToProps is a function, but i havent bothered to look into it

surprisingly, in the majority of the 3rd party libraries i use with redux they include typescript definition files. or there are typescript definitions available in separate packages at least

that mechanism only works if you use 100% compatible peripherals like the zilog PIO/SIO/etc instead of the much more common intel-compatible chips. letting the data bus float and using a 256 byte table to trap every possible value was a common trick on most z80 computers. IM0 was rarely used because it also needs hardware support, and IM1 usually jumped somewhere in ROM meaning the programmer couldn't change it to point to their own routine. So IM2 with the table trick was the only option available.
