The enablement of 64k pages on pseries platforms exposed a bug in the RTAS mechanism for updating firmware. RTAS assumes 4k for flash block and list sizes, and use of any other sizes results in a failure, even though PAPR does not specify any such requirement. This patch changes the rtas_flash module to force the use of 4k memory block and list sizes when preparing and sending a firmware image to RTAS. The rtas_flash function now uses a slab cache of 4k blocks with 4k alignment, rather than get_zeroed_page(), to allocate the memory for the flash blocks and lists. The 4k alignment requirement is specified in PAPR. Signed-off-by: John Rose <johnrose@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org> |
