Typically, peripheral FIFO addresses bypass the IOMMU, necessitating only one of the source or destination to go through it. Set "is_remote" to true to ensure both source and destination addresses pass through the IOMMU. iMX8 Spec define "Local" and "Remote" bus as below. Local bus: bypass IOMMU to directly access other peripheral register, such as FIFO. Remote bus: go through IOMMU to access system memory.

As some cases that use the meta inode for GC, there are some race issues between a foreground thread and GC thread. To handle them, we need to take care when to invalidate and wait writeback of GC pages in COW files as the case of using the meta inode. Also, a pointer from the COW inode to the original inode is required to check the state of original pages. For the former, we can solve the problem by using the meta inode for GC of COW files. Then let's get a page from the original inode in move_data_block when GCing the COW file to avoid race condition.

It can also keep old data pages when GCing the atomic file. In this case, new data can be overwritten by old data if a GC thread sets the old data page as dirty after new data page was evicted. Also, since all writes to the atomic file are redirected to COW inodes, GC for the atomic file is not working well as below. f2fs_gc(gc_type=FG_GC) - select A as a victim segment do_garbage_collect - iget atomic file's inode for block B move_data_page f2fs_do_write_data_page - use dn of cow inode - set fio->old_blkaddr from cow inode - seg_freed is 0 since block B is still valid - goto gc_more and A is selected as victim again To solve the problem, let's separate GC writes and updates in the atomic file by using the meta inode for GC writes.
