Chris Wilson 222f05c6e9 agp/intel: Reinforce the barrier after GTT updates ... commit f30d3ced9fafa03e4855508929b5b6334907f45e upstream. After changing the timing between GTT updates and execution on the GPU, we started seeing sporadic failures on Ironlake. These were narrowed down to being an insufficiently strong enough barrier/delay after updating the GTT and scheduling execution on the GPU. By forcing the uncached read, and adding the missing barrier for the singular insert_page (relocation paths), the sporadic failures go away. Fixes: 983d308cb8f6 ("agp/intel: Serialise after GTT updates") Fixes: 3497971a71d8 ("agp/intel: Flush chipset writes after updating a single PTE") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Acked-by: Andi Shyti <andi.shyti@intel.com> Cc: stable@vger.kernel.org # v4.0+ Link: https://patchwork.freedesktop.org/patch/msgid/20200410083535.25464-1-chris@chris-wilson.co.uk Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2021-03-16 16:29:12 +08:00
