Virgil Dupras f9a8e6f180 sms: Pad WIP 2020-05-15 15:41:06 -04:00
Virgil Dupras 1597f1e131 Don't generalize XYPOS just yet

Virgil Dupras ca60685067 Streamline initialization process
Instead of letting each configuration taking care of RDLN$ and
"CollapseOS" prompt, move this to BOOT to simplify xcomp units.

Initialization source code is now only for driver initialization.

Virgil Dupras 43eabf566b sms: WIP ! 2020-05-14 22:15:31 -04:00
Virgil Dupras 87b51a6261 By default, allocate about 0x100 bytes for PSP+RSP
During "make updatebootstrap", we use less than 0x20 bytes on the
PSP side and less than 0x40 bytes on the RSP one. 0x100 bytes ought
to be enough for anybody.

all core words, which greatly simplifies the bootstrapping process.

Virgil Dupras dfe474ca0e xcomp: add XCOMPILE and X[COMPILE]

Virgil Dupras dfaa1dc101 link: add "offset" argument to RLDICT
As long as our target was the first word of the "user" dict, using
target's prev to compute offset was fine, but when the target is not
the first word, this system breaks down.

This is the case when, instead of including source code in our boot
binary, we paste it in Collapse OS' prompt.

Also, adjust RC2014 recipe to include stage 3 assembling instructions
with the "paste into prompt" method.

That's my mega-commit you've all been waiting for.

The code for the shell share more routines with userspace apps than with kernel
units, because, well, its behavior is that of a userspace app, not a device
driver.

This created a weird situation with libraries and jump tables. Some routine
belonging to the `kernel/` directory felt weird there.

And then comes `apps/basic`, which will likely share even more code with the
shell. I was seeing myself creating huge jump tables to reuse code from the
shell. It didn't feel right.

Moreover, we'll probably want basic-like apps to optionnally replace the shell.

So here I am with this huge change in the project structure. I didn't test all
recipes on hardware yet, I will do later. I might have broken some...

But now, the structure feels better and the line between what belongs to
`kernel` and what belongs to `apps` feels clearer.

Virgil Dupras cdd0b64570 Modify userspace .org and RAMSTART expectations
Instead of expecting a `USER_CODE` symbol to be set, we expect `.org` to be
set in all userspace glue code. This gives us more flexibility with regards to
how we manage that.

Moreover, instead of making `USER_RAMSTART` mandatory, we make it default to
the end of the binary, which is adequate in a majority of cases.

Will be useful for my upcoming mega-commit... :)

Virgil Dupras 7cf3ed38da 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.

Virgil Dupras 7274dccbe7 Move ASCII consts to ascii.h
And made them shorter in name. The new ascii.h file allow reuse in userspace
code.

Virgil Dupras ca84b5dac8 recipes/ti84: first step
This was mostly lifted from my "tihello" example, but it required significant
adjustments.

This commit also introduces a font management system. A lot of fonts are
available online, but sources aren't always clear so to avoid copyright
landmines, I re-created my first 5x7 font from scratch.

As it is now, this resulting ROM gets "Collapse OS>" to be displayed on the
LCD screen. Much work still left to do.

Virgil Dupras 2a55bfd375 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.

Virgil Dupras b745f49186 Rename blockdev's API routines to GetB/PutB
The goal is to avoid mixing those routines with "character devices"
(acia, vpd, kbd) which aren't block devices and have routines that
have different expectations.

This is a first step to fixing #64.
