[ Upstream commit 914f8b228ede709274b8c80514b352248ec9da00 ]
This adds a function to update a CGR with new parameters. qman_create_cgr
can almost be used for this (with flags=0), but it's not suitable because
it also registers the callback function. The _safe variant was modeled off
of qman_cgr_delete_safe. However, we handle multiple arguments and a return
value.

When a bearer is removed, calling qdisc reset on a tx queue
could have a race condition with qdisc dequeue for lockless
qdisc such as pfifo_fast.
This change uses a different mechanism not relying on qdisc
implementation to achieve packet purge on bearer remove.

Sending synchronous IPIs to other CPUs involves spinning with preemption
disabled in order to wait for each IPI to finish. Keeping preemption off
for long periods of time like this is bad for system jitter, not to mention
the perf event IPIs are sent and flushed one at a time for each event for
each CPU rather than all at once for all the CPUs.
Since the way perf events are currently read is quite naive, rewrite it to
make it exploit parallelism and go much faster. IPIs for reading each perf
event are now sent to all CPUs asynchronously so that each CPU can work on
reading the events in parallel, and the dispatching CPU now sleeps rather
than spins when waiting for the IPIs to finish. Before the dispatching CPU
starts waiting though, it works on reading events for itself and then
reading events which can be read from any CPU in order to derive further
parallelism, and then waits for the IPIs to finish afterwards if they
haven't already.
Furthermore, there's now only one IPI sent to read all of a CPU's events
rather than an IPI sent for reading each event, which significantly speeds
up the event reads and reduces the number of IPIs sent.
This also checks for active SCM calls on a per-CPU basis rather than a
global basis so that unrelated CPUs don't get their counter reads skipped
and so that some CPUs can still receive fresh counter readings.
Overall, this makes the memlat driver much faster and more efficient, and
eliminates significant system jitter previously caused by IPI abuse.

This reverts commit 190be9ed11703e8e0f7c79461662634792c9beb4.
There are a number of problems with this optimization attempt, such as how
a perf error code could be returned to one of the counter values, a CPU
could enter an SCM call for just one event and result in garbage
computations or a divide-by-zero when calculating the stall percentage,
and IRQs are disabled as a heavy-handed way of preventing CPU migration.
Toss this commit out so that it can be replaced by something better.

We can skip the locking and other overhead of perf_event_read_value()
when we know in advance that the perf event in question can be read from
the current CPU. This occurs when either the perf event permits reads
from CPUs other than the one its on, or when the CPU doing the reads is
the same CPU that owns the perf event.
Our PMU drivers only set two possible values for `readable_on_cpus`:
CPU_MASK_ALL or nothing. As such, we can simply check for CPU_MASK_ALL
beforehand in order to determine if the perf event allows non-local
reads.
We can also reduce the scope of under_scm_call() since we now know which
CPU we're reading a perf event from, thus reducing the false positive
rate of under_scm_call() as it is now per-CPU.

memlat works based on perf event to calculate algorithm.
Perf event needs IPI to read count from other CPU.
However, if the CPU is under heavy scm call(+20ms), it could
be stuck until the CPU could complete the scm call.
It would cause long latency.
This patch adds global atomic count to check whether scm is
going. If it's under going, memlat doesn't invoke perf event
function to avoid IPI stuck. Although there is still race to
check it, the race should be small enough so effectivey, it
mitigate such long latency.
Please check to memlat owner what happens when read_event
sometimes returns zero due to scm call in parallel.

The quick hack to fix this (proper fix is too much chrun for non active

'bootloader_load_kernel' and 'bootloader_chksum_time' are
redundant information. As the entries in IMEM have a limit
(as of now 8 entries), recreate them from *_start and *_done
variants, which are populated from the bootloader.

CPU spm is programmed to handshake with rpm for single cpu devices.
If cluster level LPM is not selected even then spm handshakes with
rpm.
Fix this issue by allowing rpm handshake only if cluster level
LPM is selected.
