From ca2552461e12b4b36af73e4e7f350fd08527f0b0 Mon Sep 17 00:00:00 2001 From: Oliver Schmidt Date: Tue, 4 Aug 2015 13:48:08 +0200 Subject: [PATCH] Adjusted retro target clock to "new" DNS resolver. The DNS resolver requires 1/4 sec clock resolution. The retro targets had a 1/2 sec clock resolution (optimized for the 1/2 sec TCP timer) resulting in DNS resolver timeouts being 0. Therefore the retro target clock resolution is now increased to 1/4 sec. --- cpu/6502/6502def.h | 2 +- cpu/6502/sys/clock.c | 7 ++----- platform/apple2enh/sys/clock.c | 2 +- 3 files changed, 4 insertions(+), 7 deletions(-) diff --git a/cpu/6502/6502def.h b/cpu/6502/6502def.h index 352acc5a5..164af5e67 100644 --- a/cpu/6502/6502def.h +++ b/cpu/6502/6502def.h @@ -61,7 +61,7 @@ typedef int32_t s32_t; #define HAVE_SNPRINTF #define snprintf(buf, len, ...) sprintf(buf, __VA_ARGS__) -#define CLOCK_CONF_SECOND 2 +#define CLOCK_CONF_SECOND 4 typedef unsigned short clock_time_t; typedef unsigned short uip_stats_t; diff --git a/cpu/6502/sys/clock.c b/cpu/6502/sys/clock.c index c23e14f65..33d2da865 100644 --- a/cpu/6502/sys/clock.c +++ b/cpu/6502/sys/clock.c @@ -45,11 +45,8 @@ clock_time(void) * of overhead for cc65 targets. * On the other hand we want to avoid wrapping around frequently so the idea * is to reduce the clock resolution to the bare minimum.
