Implementing those is completely unecessary.

Just a gentle ping on this. Already got the Acked-by from Daniel, but I need some of the nouveau guys to test this since I can only compile test it. Regards, Christian.

Upcasting using a container_of macro is more typesafe, faster and easier for the compiler to optimize.

While working on TTM cleanups I've found that the io_reserve_lru used by Nouveau is actually not working at all. In general we should remove driver specific handling from the memory management, so this patch moves the io_reserve_lru handling into Nouveau instead. The patch should be functional correct, but is only compile tested! Signed-off-by: Christian König <christian.koenig at

Hi guys, I've already send this out in September last year, but only got a response from Daniel. Could you guys please test this and tell me what you think about it? Basically I'm trying to remove all driver specific features from TTM which don't need to be inside the framework. Thanks, Christian.

We are trying to remove the io_lru handling and depend on zero init base, offset and addr here. v2: init addr as well Signed-off-by: Christian K?nig <christian.koenig at amd.com> --- drivers/gpu/drm/ttm/ttm_bo.c | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/drivers/gpu/drm/ttm/ttm_bo.c b/drivers/gpu/drm/ttm/ttm_bo.c index e3931e515906..772c640a6046 100644 ---

This series depends on the previously posted reservation api patches. 2 of them are not yet in for-next-fences branch of git://git.linaro.org/people/sumit.semwal/linux-3.x.git The missing patches are still in my vmwgfx_wip branch at git://people.freedesktop.org/~mlankhorst/linux All ttm drivers are converted to the fence api, fence_lock is removed and rcu is used in its place. qxl is the first

This series applies on top of the driver-core-next branch of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git Before converting ttm to the new fence interface I had to fix some drivers to require a reservation before poking with fence_obj. After flipping the switch RCU becomes available instead, and the extra reservations can be dropped again. :-) I've done at least basic

Hi guys, so I got some hardware and tested this and after hammering out tons of typos it now seems to work fine. Could you give it more testing? Thanks in advance, Christian

fence_is_signaled callback should support being run in atomic context, but not in irq context.

Rename the embedded struct vma_offset_manager, new name is _vma_manager. ttm_bo_device.vma_manager changed to a pointer. The ttm_bo_device_init() function gets an additional vma_manager argument which allows to initialize ttm with a different vma manager. When passing NULL the embedded _vma_manager is used. All callers are updated to pass NULL, so the behavior doesn't change. Signed-off-by:
