To avoid this pain I changed the driver to use only cached access to memory. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> --- Changes to last version: - Use inline functions for dma_sync_* instead of macros (suggested by Ralf) - added Kconfig change to make selection for similair SGI boxes easier hrm, could you rediff? it doesn't seem to apply |
