Author: cognet Date: Sat Aug 10 00:31:49 2013 New Revision: 254171 URL: http://svnweb.freebsd.org/changeset/base/254171 Log: - The address lies in the bus space handle, not in the cookie - Use the right address when calling kva_free() (Is there any reason why the s3c2xx0 comes with its own version of bs_map/ bs_unmap ? It seems to be just the same as in bus_space_generic.c) Modified: head/sys/arm/s3c2xx0/s3c2xx0_space.c Modified: head/sys/arm/s3c2xx0/s3c2xx0_space.c ============================================================================== --- head/sys/arm/s3c2xx0/s3c2xx0_space.c Sat Aug 10 00:06:56 2013 (r254170) +++ head/sys/arm/s3c2xx0/s3c2xx0_space.c Sat Aug 10 00:31:49 2013 (r254171) @@ -200,21 +200,21 @@ s3c2xx0_bs_map(void *t, bus_addr_t bpa, void s3c2xx0_bs_unmap(void *t, bus_space_handle_t h, bus_size_t size) { - vm_offset_t va, endva; + vm_offset_t va, endva, origva; - if (pmap_devmap_find_va((vm_offset_t)t, size) != NULL) { + if (pmap_devmap_find_va((vm_offset_t)h, size) != NULL) { /* Device was statically mapped; nothing to do. */ return; } - endva = round_page((vm_offset_t)t + size); - va = trunc_page((vm_offset_t)t); + endva = round_page((vm_offset_t)h + size); + origva = va = trunc_page((vm_offset_t)h); while (va < endva) { pmap_kremove(va); va += PAGE_SIZE; } - kva_free(va, endva - va); + kva_free(va, endva - origva); } int
