Loop conditions of timeout checking introduced in commit
21094783114b9314d57f412196544a34b3a40f4a ("gpu: nvgpu: Use timeout retry
API in mm_gk20a.c") were flipped by accident, so each usage in a loop
actually did not wait enough but ran only one iteration. Fix the
conditions to loop as long as the timeout is NOT expired.
Also restore l2 flush timeout to 10 ms from 1, which was done in commit
030ef82bdd474ef4261a2f40995b8db57857899e ("gpu: nvgpu: increase l2 flush
timeout") but overwritten by the above "use timeout" commit.

fifo_sched_disable_true_v() returns 1 and this
value is being right shifted by runlist_id.
This will work only if runlist_id is 0. For runlist_id
other than 0, 1 right shifted by runlist_id will return 0 and
engine will remain disabled. fifo_sched_disable_true_v()
should be left shifted by runlist_id to fix the bug.

In case one job completes just around timeout boundary,
it is possible that we launch both clean up worker and
timeout worker for same job
Then in clean up worker we try to cancel timeout
worker, and in timeout worker we try to wait for clean
up to finish which leads to deadlock with below stacks
stack 1:

Interface will accept dmabuf_fd of the buffer in vidmem,

to copy data across API, size of read/write and
command indicating either read or write operation
API will first parse all the inputs, and then call
gk20a_vidbuf_access_memory() to complete fb access
gk20a_vidbuf_access_memory() will then just use
gk20a_mem_rd_n() or gk20a_mem_wr_n() depending

gm20b_init_gr does not inherit the ops set by gk20a_init_gr_ops, and the
gr.setup_rop_mapping HAL was not set there, so it was not set for chips
that inherit from gm20b_init_gr and do not override it explicitly.
Set the pointer in gm20b_init_gr, which other chips inherit, and delete
the surrounding if condition from the call, making sure that future
users always call it, because there is an implementation since the
earliest supported chip.

Currently, in gk20a_scale_target, we set clock frequency
even if it is equivalent to the rate previously requested by
the governor. This change adds a check to bypass this in
case new_frequency == prev_frequency.
These clocking operations result in multiple BPMP calls, and add
significant overhead to submit time. So, we avoid these
operations when possible.

We right now obtain pm_qos frequency requirments in
qos notifier callback gk20a_scale_qos_notify()
But now we want to limit GPU frequencies based on
frequency limited from devfreq nodes
And devfreq requirement should precede over
qos requirements
Hence, move all frequency estimation and clipping
to function gk20a_scale_target() which sets the

In calls to gk20a_fifo_recover() we pass a bitfield of engines to
recover. We generate the bitfield by acquiring engine id from FIFO,
and using BIT(). If GR engine is now known, the resulting engine ID is
u32 with all bits set, which cannot be passed to BIT().
gk20a_fifo_recover() can already deal with all bits set, so pass that
verbatim instead.
