From 05099149f193cac0c81b0129c17feb78b1a9681a Mon Sep 17 00:00:00 2001 From: Michael Sevakis Date: Sun, 6 Apr 2008 04:34:57 +0000 Subject: Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16981 a1c6a512-1295-4272-9138-f99709370657 --- firmware/kernel.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'firmware/kernel.c') diff --git a/firmware/kernel.c b/firmware/kernel.c index 1882855..8ee553e 100644 --- a/firmware/kernel.c +++ b/firmware/kernel.c @@ -49,7 +49,7 @@ #endif #if !defined(CPU_PP) || !defined(BOOTLOADER) -volatile long current_tick NOCACHEDATA_ATTR = 0; +volatile long current_tick SHAREDDATA_ATTR = 0; #endif void (*tick_funcs[MAX_NUM_TICK_TASKS])(void); @@ -62,7 +62,7 @@ static struct int count; struct event_queue *queues[MAX_NUM_QUEUES]; IF_COP( struct corelock cl; ) -} all_queues NOCACHEBSS_ATTR; +} all_queues SHAREDBSS_ATTR; /**************************************************************************** * Standard kernel stuff -- cgit v1.1
