No other driver uses this, and userspace should be responsible for handling locking between them if they share BOs. Signed-off-by:Ben Skeggs <bskeggs@redhat.com>

This fixes a race condition between fbcon acceleration and TTM buffer moves. To reproduce: - start X - switch to vt and "while (true); do dmesg; done" - switch to another vt and "sleep 2 && cat /path/to/debugfs/dri/0/evict_vram" - switch back to vt running dmesg We don't make use of this on any other channel yet, they're currently protected by drm_global_mutex. This will change in the near future. Signed-off-by: -

A future commit will add locking to the DRM's channel, and there's numerous problems that come up if we allow printk from an interrupt context to be accelerated. It seems saner to just disallow it completely. As a nice side-effect, all the "to accel or not to accel" logic gets moved out of the chipset-specific code. Signed-off-by: -

Rather than re-implementing in the Radeon driver, Use the execbuf / cs / pushbuf utilities that comes with TTM. This comes with an even greater benefit now that many spinlocks have been optimized away... Signed-off-by:

This patch attempts to fix up shortcomings with the current calling sequences. 1) There's a fastpath where no locking occurs and only io_mem_reserved is called to obtain needed info for mapping. The fastpath is set per memory type manager. 2) If the fastpath is disabled, io_mem_reserve and io_mem_free will be exactly balanced and not called recursively for the same struct ttm_mem_reg. 3) Optionally the driver can choose to enable a per memory type manager LRU eviction mechanism that, when io_mem_reserve returns -EAGAIN will attempt to kill user-space mappings of memory in that manager to free up needed resources Signed-off-by:

Rather than having the driver supply the validation sequence, leave that responsibility to TTM. This saves some confusion and a function argument. Signed-off-by:

The bo lock used only to protect the bo sync object members, and since it is a per bo lock, fencing a buffer list will see a lot of locks and unlocks. Replace it with a per-device lock that protects the sync object members on *all* bos. Reading and setting these members will always be very quick, so the risc of heavy lock contention is microscopic. Note that waiting for sync objects will always take place outside of this lock. The bo device fence lock will eventually be replaced with a seqlock / rcu mechanism so we can determine that a bo is idle under a rcu / read seqlock. However this change will allow us to batch fencing and unreserving of buffers with a minimal amount of locking. Signed-off-by:

Makes it possible to reserve a list of buffer objects with a single spin lock / unlock if there is no contention. Should improve cpu usage on SMP kernels. v2: Initialize private list members on reserve and don't call ttm_bo_list_ref_sub() with zero put_count. Signed-off-by:
