https://bugzilla.kernel.org/show_bug.cgi?id=204145 --- Comment #16 from Shawn Anastasio (shawn@xxxxxxxxxx) --- Created attachment 283799 --> https://bugzilla.kernel.org/attachment.cgi?id=283799&action=edit test patch #1 Though I'm not familiar with this code, a quick spot check shows what I believe to be an inconsistency with the commit's claim of functional identicality. Namely, the previous caller of __dma_get_coherent_pfn (now arch_dma_coherent_to_pfn) would explicitly modify the vm_area to mark it as uncacheable in the !coherent case. It seems the new caller (dma_common_mmap) does not do this. I have written a small patch to restore the previous behavior (I think). Note that this probably isn't upstreamable since this fix should probably go somewhere in the powerpc arch code rather than the dma core. Tim, since you're the only one who can easily reproduce this, would you mind giving this patch a shot? -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
