From 4f2d40ca35e0e39886dc881d06256fc25ba27a77 Mon Sep 17 00:00:00 2001 From: user Date: Thu, 16 Jul 2026 12:20:57 +0200 Subject: fs rewrite stage 2: inodes + root directory (block-based, persistent) - fs.asm: a real block filesystem on the persistent block device - superblock, block/inode bitmaps, a 32-entry inode table (type, size, 8 direct block pointers -> files up to 2 KiB), and a root directory of 16-byte entries. Metadata cached in WRAMX; one-block data cache streams file/dir blocks. - same syscall interface (open/getb/putb/list/remove) -> tools unchanged; ls now enumerates until flist() runs out (16 files, was hardcoded 8). - old 8-slot WRAM FS removed; cart RAM partitioned: process banks 0-7, disk 8-11. - two register-clobber bugs fixed: alloc_block/alloc_inode returned the bitmap-block number (write_bitmap clobbers C); db_use loaded the wrong block on a transition (db_flush->write_block clobbers C) -> multi-block files broke. - verified: 10+ files, multi-block (300-byte) files, delete, and persistence across reboots. Debug 'blk' disk tool retained (fill/peek). - README: document the block filesystem. --- c/ls.c | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) (limited to 'c/ls.c') diff --git a/c/ls.c b/c/ls.c index f7e5161..5d5ce43 100644 --- a/c/ls.c +++ b/c/ls.c @@ -1,9 +1,7 @@ #include "gbos.h" -/* ls: list files in the RAM filesystem. */ +/* ls: list files in the filesystem. */ void main(void) { - char name[9]; + char name[16]; unsigned char i; - for (i = 0; i < 8; i++) { - if (flist(i, name)) { name[8] = 0; puts(name); nl(); } - } + for (i = 0; flist(i, name); i++) { name[15] = 0; puts(name); nl(); } } -- cgit v1.3.1-sl0p
