As for the buddy system, much of docs mention the physical address of the first page frame of a block should be a multiple of the group size. For example, the initial address of a 16-page-frame block should be 16-page aligned. I happened to encounted an issue that the physical addresss pf the block is not 4-page aligned(0x36c9000) while the order of the block is 2. I want to know what out of buddy algorithm depend on this feature? My problem seems to happen in schedule()->context_switch() call, but so far I didn't figure out the root cause.
It seems nothing depend on this feature. the problem you encounted is the kernel task stack should be 2-page aligned. -Aubrey - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
