* drm/vmwgfx: Return 0 when gmrid::get_node runs out of ID'sDeepak Rawat2019-03-271-1/+1
| | | | | | | | | | | | | | | | | commit 4b9ce3a651a37c60527101db4451a315a8b9588f upstream. If it's not a system error and get_node implementation accommodate the buffer object then it should return 0 with memm::mm_node set to NULL. v2: Test for id != -ENOMEM instead of id == -ENOSPC.

The new IDA API is similar to ida_simple_get() but better named. The internal restructuring of the IDA code removes the bitmap preallocation nonsense.

| * drm/vmwgfx: Convert to new IDA APIMatthew Wilcox2018-08-211-29/+12
| | | | | | | | | | | | | | | | | | Reorder allocation to avoid an awkward lock/unlock/lock sequence. Simpler code due to being able to use ida_alloc_max(), even if we can't eliminate the driver's spinlock.

* vmwgfx: Restrict number of GMR pages to device limitThomas Hellstrom2011-09-011-11/+35
| | | | | | | | | | | | | When GMR2 is available, make sure we restrict the number of used GMR pages to the limit indicated by the device. This is done by failing a GMRID allocation if the total number of GMR pages exceeds the limit. As a result TTM will then start evicting buffers in GMR memory on a LRU basis until the allocation succeeds.
