[Intel-gfx] [PATCH 0/3] Engine busyness v2

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The latest GuC implements a new and improved scheme for tracking
engine busyness. So make use of it.

Note that this change comes along with a new set of PMU counters. The
old counters have a fundamental problem that they are defined in terms
of wall time but the sampling is now all done by the GPU in terms of
clock ticks. This leads to issues with timebase conversion, some of
which are non-trivial.

For existing platforms, the old counters will still be updated by the
new scheme and will still suffer all the same issues. For newer
platforms (MTL onwards), the old counters are no longer supported.

Instead, there is a new set of tick based counters. These include the
actual busyness count per engine plus a total ticks count. The
intention is that they should be queried as an atomic pair and used
together to determine a busyness percentage. No assumptions may be made
about tick frequencies or relations to wall time.

[Intel-gfx] [PATCH 1/3] drm/i915/guc: Support new and improved engine busyness

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The GuC has been extended to support a much more friendly engine
busyness interface. So partition the old interface into a 'busy_v1'
space and add 'busy_v2' support alongside. And if v2 is available, use
that in preference to v1. Note that v2 provides extra features over
and above v1 which will be exposed via PMU in subsequent patches.

Since we are thinking of using the existing busyness counter to expose 
the v2 values, we can drop the last sentence from above.

Overall, I would suggest having the renames as a separate patch. Would 
make the review easier.

engine is not being passed as NULL in this patch, so we can drop the 
checks in this function.

Is it possible to split the code in if/else blocks into seperate 
functions and do away with using guc_vf == ~0U to switch between the 2 logics.

Recommending splitting the vf id based counter support to a future patch.

engine record and global record could use separate functions, maybe like
__busy_v2_get_engine_usage_record
__busy_v2_get_global_usage_record

I originally had them split. But there is so much common code that it 
was much simpler code-wise to have a single function.

[Intel-gfx] [PATCH 2/3] drm/i915/mtl: Add a PMU counter for total active ticks

[John.C.Harrison]

From: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com>

Current engine busyness interface exposed by GuC has a few issues:

- The busyness of active engine is calculated using 2 values provided by
  GuC and is prone to race between CPU reading those values and GuC
  updating them. Any sort of HW synchronization would be at the cost of
  scheduling latencies.

- GuC provides only 32 bit values for busyness and KMD has to run a
  worker to extend the values to 64 bit. In addition KMD also needs to
  extend the GT timestamp to 64 bits so that it can be used to calculate
  active busyness for an engine.

To address these issues, GuC provides a new interface to calculate
engine busyness. GuC accumulates the busyness ticks in a 64 bit value
and also internally updates the busyness for an active context using a
periodic timer. This simplifies the KMD implementation such that KMD
only needs to relay the busyness value to the user.

In addition to fixing the interface, GuC also provides a periodically
total active ticks that the GT has been running for. This counter is
exposed to the user so that the % busyness can be calculated as follows:

busyness % = (engine active ticks/total active ticks) * 100.

Implement the new interface and start by adding a new counter for total
active ticks.

AFAIU I915_PMU_TOTAL_ACTIVE_TICKS only runs when GT is awake, right?

So if GT is awake 10% of the time, and engine is busy that 100% of that 
time, which is 10% of the real/wall time, the busyness by this formula 
comes up as 100%. Which wouldn't be useful for intel_gpu_top and alike.

How to scale it back to wall time? Again AFAIU there is no info about 
tick frequency, so how does one know what a delta in total active ticks 
means?

Going back on the higher level, I am not convinced we need to add a new 
uapi just for MTL. If the tick period is known internally we could just 
use v2 internally and expose the current uapi using it.

Any timebase conversion error is unlikely to be relevant because 
userspace only looks at deltas over relatively short periods (seconds). 
Ie. I don't think that the clock drift error would accumulate so it 
would need to be really huge to be relevant over short sampling periods.

Looks like I got this wrong. The implementation is actually updating the 
total active ticks even when idle and that addresses the concern above.

We did plan to support the total active ticks in future platforms for 
other use cases and thought this would be a good place to initiate the 
support. At the same time, I agree that existing interface can still 
work with the v2 GuC interface. I will post that.

At some point we may need to think about long running workloads, but 
that may require a different counter anyways, so I would not address it 
here.

Thanks,

[Intel-gfx] [PATCH 3/3] drm/i915/mtl: Add counters for engine busyness ticks

[John.C.Harrison]

From: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com>

In new version of GuC engine busyness, GuC provides engine busyness
ticks as a 64 bit counter. Add a new counter to relay this value to the
user as is.

Why is this changing the logic for the existing counter? It is not

Okay, or add the unit explicitly in the descriptor array as global

Are we sure the enabled status tracking is needed for a non-sampling event?

These vfuncs are all zero initialised and checked for null before being 
called. And the intention was that MTL would not support the old API as 
it not a good fit for current hardware. However, that plan was rejected 
and the whole v2 implementation is currently shelved for upstream due to 
power implications that need to be resolved.
