You can reserve a specific area using reserve_bootmem, so that you don't have to rely on alloc_bootmem_low returning memory from the correct zone, e.g. in atari_stram_reserve_pages you already have a pointer to the start of free memory. In general stram.c could use a major cleanup. It would be better if it used resources like amiga/chipram.c. > @@ -90,11 +90,15 @@ > /* values for flags field */ > #define BLOCK_FREE 0x01 /* free structure in the BLOCKs pool */ > #define BLOCK_KMALLOCED 0x02 /* structure allocated by kmalloc() */ > +#define BLOCK_POOL 0x04 /* block allocated from static pool */ > #define BLOCK_GFP 0x08 /* block allocated with __get_dma_pages() */ In the end it should simply use a single allocation type, if there is something that needs ST-RAM before the allocator is initialized, it either has to be delayed or special cased. bye, Roman -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
