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.	2019-11-14 10:14:15 -05:00
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.	2019-11-13 20:38:06 -05:00
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.	2019-11-04 09:55:12 -05:00
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.	2019-10-30 16:59:35 -04:00

Virgil Dupras	c18d42f08b	fs: further adjust to previous blkdev refactoring ... Previous refacoring broke all seek/tell within fs. fs handles now lost the responsibility to keep track of current position. It's blkdev's job.	2019-06-04 20:45:01 -04:00

Virgil Dupras	2e8af376e3	pgm: new kernel module ... The pgm module implements a shell hook so that when an unknown command is typed, we look into the mounted filesystem and look for a file with the same name as the command. If we find one, we load it in memory and run it.	2019-05-31 14:54:15 -04:00
