powerpc/powernv/ioda2: Reduce upper limit for DMA window size (retry) # # We use PHB in mode1 which uses bit 59 to select a correct DMA window. # However there is mode2 which uses bits 59:55 and allows up to 32 DMA # windows per a PE. # # Even though documentation does not clearly specify that, it seems that # the actual hardware does not support bits 59:55 even in mode1, in other # words we can create a window as big as 1<<58 but DMA simply won't work. # # This reduces the upper limit from 59 to 55 bits to let the userspace know # about the hardware limits. # # Fixes: ce57c6610cc2 "Merge branch 'topic/ppc-kvm' into next" # Signed-off-by: Alexey Kardashevskiy # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version
