Hi Benjamin,
If two touches are under the dmax distance, it looks like they can now
be assigned to the same slot. Add a band aid to prevent such situation
and be able to use the balanced slot assignment.
Yes, great find. You patch is correct, but it is not a band aid, but a
result stemming

Hi,
So, it occurs that the balanced slots assignment introduced in v4.0 had some

This patch fixes a kernel panic which occurs when buf_list is empty. This can
happen occasionally when user space is under heavy load (e.g. due to image
processing on the CPU) and new buffers aren't re-queued fast enough. In that
case, vb2_start_streaming_called can return true, but when the

The recent inclusion of a deassignment cost in the slot assignment
algorithm did not properly account for the corner cases where the
solutions are overcovered. This patch makes sure the resulting assignment
is unique, allocating new slots when necessary.

When slowly dropping 1, 2 and then 3 fingers on an image sensor touchpad,
we can see that the first finger gets reassigned a new slot while it did
not move. This is due to the kernel tracking algorithm which can not
assign correctly the 3 touches, being out of slots.

tty_name no longer uses the buf parameter, so remove it along with all
the 64 byte stack buffers that used to be passed in.

All users of tty_name pass the return value directly to a printf
function, so we might as well use tty-name directly instead of
copying it to a user-supplied (stack) buffer.

This reverts commit 09d042a2eb90 (Revert Input: synaptics - use dmax in
input_mt_assign_slots)
Now that balanced slots assignments seem to be fixed, let's
reenable the use in synaptics.c and wait for users to complain
if there are still problems.
