[IA64] agp/hp-agp: Allow binding user memory to the AGP GART
dmesg reports: [   29.365973] [TTM] AGP Bind memory failed. [   29.366015] radeon 0000:80:00.0: object_init failed for (4096, 0x00000002) [   29.366052] radeon 0000:80:00.0: (-22) create WB bo failed [   29.366087] radeon 0000:80:00.0: Disabling GPU acceleration [   29.366124] [drm] radeon: cp finalized [   29.366168] [drm] radeon: cp finalized [   29.366210] [TTM] Finalizing pool allocator. [   29.366924] [TTM] Zone  kernel: Used memory at exit: 0 kiB. [   29.366961] [TTM] Zone   dma32: Used memory at exit: 0 kiB. [   29.366996] [drm] radeon: ttm finalized [   29.367030] [drm] Forcing AGP to PCI mode This patch allows binding user memory to the AGP GART on zx1-based systems. dmesg thus no more complains about AGP bind memory failure, disabled GPU acceleration or AGP mode forced to PCI. Original work from Francisco Jerez in agp/amd-k7 (https://lkml.org/lkml/2010/10/15/469). Tested-by: Émeric Maschino <emeric.maschino@gmail.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
