From bf647581fbad727ad22021d345d3955abf44c2f3 Mon Sep 17 00:00:00 2001 From: user Date: Fri, 17 Jul 2026 20:22:34 +0200 Subject: net: SYS_POLLCON + larger console ring for link-injected input Programs that own their main loop (the IRC client) need to poll for typed input without blocking. pollin() only sees the on-screen keyboard; bytes injected over the link (gbhub 'type', for scripted/hub-driven sessions) land in the kernel console ring, previously only drained by the blocking KGetc path. Add SYS_POLLCON: a non-blocking con_pop for userland. Also enlarge that console ring 16 -> 64. One net_pump drains an entire serial burst into the ring at once, so a whole injected command line has to fit or bytes are dropped and lines merge (a 20-char command came out truncated and glued to the next). 64 covers a full line; mask stays a power of two. --- src/net.asm | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'src/net.asm') diff --git a/src/net.asm b/src/net.asm index f2c4279..8309242 100644 --- a/src/net.asm +++ b/src/net.asm @@ -54,6 +54,16 @@ sys_srecv_nb:: and a ; CF = 0 (got a byte) ret +; sys_pollcon() -> A = a queued console-ring byte (link-injected input, +; e.g. gbhub 'type'), or 0 if none.
