Hi everyone, This is the ninth and hopefully last incarnation of this set of patches. It enables device drivers to resize and most likely also relocate the PCI BAR of devices they manage to allow the CPU to access all of the device local memory at once. This is very useful for GFX device drivers where the default PCI BAR is only about 256MB in size for compatibility reasons, but the device easily have multiple gigabyte of local memory. Some changes since the last version: 1. Rebased on drm-next, so should be ready to be merged for 4.15. 2. The fixup of the 64bit root window on AMD Family 15h CPUs/APUs is only enabled when we compile a kernel supporting that hw. 3. Some minor error handling improvements for the amdgpu side. We now gracefully abort driver loading in case of a critical error instead of calling BUG(). Bjorn any more comments or can we finally get this into 4.15? I will remove the version tags from the patches when I send you a pull request if you want this. I only work on this as a background task, so sorry for the ~3 month delay between each version of the patchset. Regards, Christian. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
