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 --- apps/plugins/mpegplayer/disk_buf.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'apps/plugins/mpegplayer/disk_buf.c') diff --git a/apps/plugins/mpegplayer/disk_buf.c b/apps/plugins/mpegplayer/disk_buf.c index 289918fc63..46a060221d 100644 --- a/apps/plugins/mpegplayer/disk_buf.c +++ b/apps/plugins/mpegplayer/disk_buf.c @@ -21,12 +21,12 @@ #include "plugin.h" #include "mpegplayer.h" -static struct mutex disk_buf_mtx NOCACHEBSS_ATTR; -static struct event_queue disk_buf_queue NOCACHEBSS_ATTR; -static struct queue_sender_list disk_buf_queue_send NOCACHEBSS_ATTR; +static struct mutex disk_buf_mtx SHAREDBSS_ATTR; +static struct event_queue disk_buf_queue SHAREDBSS_ATTR; +static struct queue_sender_list disk_buf_queue_send SHAREDBSS_ATTR; static uint32_t disk_buf_stack[DEFAULT_STACK_SIZE*2/sizeof(uint32_t)]; -struct disk_buf disk_buf NOCACHEBSS_ATTR; +struct disk_buf disk_buf SHAREDBSS_ATTR; static struct list_item nf_list; static inline void disk_buf_lock(void) @@ -566,7 +566,7 @@ static int disk_buf_probe(off_t start, size_t length, { if (disk_buf.cache[page] != tag) { - static struct dbuf_range rng NOCACHEBSS_ATTR; + static struct dbuf_range rng IBSS_ATTR; DEBUGF("disk_buf: cache miss\n"); rng.tag_start = tag; rng.tag_end = tag_end; -- cgit v1.2.3
