No users are left, kill it off! :D Conversion to the reservation api is next on the list, after that the functionality can be restored with rcu.

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:

Hi guys, at least on amdgpu and radeon the page array allocated by ttm_dma_tt_init is completely unused in the case of DMA-buf sharing. So I'm trying to get rid of that by only allocating the DMA address array. Now the only other user of DMA-buf together with ttm_dma_tt_init is Nouveau. So my question is are you guys using the page array anywhere in your kernel driver in case of a

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.

Hi Jens, this series removes the revalidate_disk() function, which has been a really odd duck in the last years. The prime reason why most people use it is because it propagates a size change from the gendisk to the block_device structure. But it also calls into the rather ill defined ->revalidate_disk method which is rather useless for the callers. So this adds a new helper to just

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.

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

The ttm_mem_io_* functions are actually internal to TTM and shouldn't be used in a driver. Instead call the qxl_ttm_io_mem_reserve() function directly.

Dynamically resizing the framebuffer on nv04 was like playing Russian roulette (and it often happened gratuitously) because it seems unable to scan out from buffers above 16MB. This patch splits the mappable VRAM into two chunks when that's the case, and makes the higher one to be used as well when applicable. Signed-off-by: Francisco Jerez <currojerez at riseup.net> ---
