Not a bad start, but that needs quite some more work.
First of all please rebase on top of current drm-misc-next, a whole
bunch of the stuff you want to trace here was already removed or is
about to be removed.
Then concentrate on the necessary trace points, for example

This patch provides infrastructure for deferring buffer frees.

Functions in the atomic commit tail are not allowed to acquire the
dmabuf's reservation lock. So we cannot legally call the GEM object's

Instead vmap the cursor BO in prepare_fb and vunmap it in cleanup_fb.
The cursor plane state stores the mapping's address. T

For v5, I moved the non-assignment of pdev in i915 into a separate
patch as suggested by Chris. Hopefully, this will help with merging the
patches into the rsp i915 trees. The core and vmwgfx changes have been
merged into drm-tip already.

Another issue found by KASAN. The bit finding is buried inside the
dp_for_each_set_bit() macro (that passes on to for_each_set_bit() that
calls the bit stuff. These bit functions want an unsigned long pointer
as input and just dumbly casting leads to out-of-bounds accesses.
In order to measure how much memory a process actually consumes, it is
necessary to include the DMA buffer sizes for that process in the memory
accounting. Since the handle to DMA buffers are raw FDs, it is important
to be able to identify which processes have FD references to a DMA buffer.

This patch allows statistics to be enabled for each DMA-BUF in

The cursor uses two BOs in video RAM to implement double buffering. Store
both in struct ast_cursor_plane.

As HW cursor BOs never move, we can store the offset in VRAM in the
cursor-plane's HWC state. This removes the last possible source of
runtime errors from atomic_update.

GEM vmap operations are not allowed in commit tail. Therefore, we cannot
map the cursor source BO in atomic_update. Instead do this in prepare_fb.
There was no pin operation for the BO, so add this as well.
Hence the cursor source BO is now mapped while it's being displayed. The

The BOs of the hardware cursor are now mapped permanently while the
cursor plane is being used. This reduces the CPU overhead of the cursor
plane's atomic_update function.
The change also resolves a problem with the vmap call in the commit tail.
The vmap implementation could acquire the DMA reserv
Use AST_MAX_HWC_HEIGHT for setting offset_y in the cursor plane's
atomic_check. The code used AST_MAX_HWC_WIDTH instead. This worked
because both constants has the same value.
