blockdev: make implementors "random access" This huge refactoring remove the Seek and Tell routine from blockdev implementation requirements and change GetC and PutC's API so that they take an address to read and write (through HL/DE) at each call. The "PTR" approach in blockdev implementation was very redundant from device to device and it made more sense to generalize. It's possible that future device aren't "random access", but we'll be able to add more device types later. Another important change in this commit is that the "blockdev handle" is now opaque. Previously, consumers of the API would happily call routines directly from one of the 4 offsets. We can't do that any more. This makes the API more solid for future improvements. This change forced me to change a lot of things in fs, but overall, things are now simpler. No more `FS_PTR`: the "device handle" now holds the active pointer. Lots, lots of changes, but it also feels a lot cleaner and solid.

zasm: rename #inc to .inc scas, it's not needed any more.
2019-10-07 05:32:23 +11:00
.inc "core.asm"
Extract str.asm from core.asm and make core included by userspace Most of register fiddling routines (which is now the only thing contained in care.asm) are used by almost all userspace apps, often in inner loops. That makes the penalty of using jump tables for those a bit too high. Moreover, it burdens jump tables needlessly. Because this unit is very small (now that string routines are out), it makes sense to always include it in binaries.

stdio: remove a layer of indirection in GetC/PutC We use zasm's ability to use labels in .equ directive. We didn't do it before because for a while, we were in between scas and zasm (scas was used in automated tests) so we needed to use the lowest common denominator: zasm doesn't have macros and scas can't use labels in .equ directives. This forced us to add this layer of indirection. But now that we are completely cut from scas' dependency, we can use this nice zasm's ability.

shell/stdio: decouple from blkdev (again) Move load/save to blkdev_cmds and add a new "poke" builtin shell cmd that is the mirror of "peek" and strictly uses stdio (no blkdev involved). This allows us to slim the minimal OS size but, more importantly, change the behavior of "load" so that we don't expect GetC to block until Z is set. This way, using "load X" with X being larger than the blkdev size won't block forever. This also brings our RC2014 minimal kernel below the 1K mark again.
