Bah, I think I found the problem: +static inline void *drm_vmalloc_dma(unsigned long size) +{ +#if defined(__powerpc__) && defined(CONFIG_NOT_COHERENT_CACHE) + return __vmalloc(size, GFP_KERNEL | __GFP_HIGHMEM, + PAGE_KERNEL | _PAGE_NO_CACHE); +#else + return vmalloc_32(size); +#endif +} +
Remove the GFP_HIGHMEM from the above. It looks like our cache flushing isn't going to work for highmem, it would need some kmap's for that. Ben. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
