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/drivers/fat.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'firmware/drivers/fat.c') diff --git a/firmware/drivers/fat.c b/firmware/drivers/fat.c index a538b92695..002e100405 100644 --- a/firmware/drivers/fat.c +++ b/firmware/drivers/fat.c @@ -201,7 +201,7 @@ struct fat_cache_entry static char fat_cache_sectors[FAT_CACHE_SIZE][SECTOR_SIZE]; static struct fat_cache_entry fat_cache[FAT_CACHE_SIZE]; -static struct mutex cache_mutex NOCACHEBSS_ATTR; +static struct mutex cache_mutex SHAREDBSS_ATTR; #if defined(HAVE_HOTSWAP) && !defined(HAVE_MMC) /* A better condition ?? */ void fat_lock(void) -- cgit v1.2.3
