Up to now, subslice mask was assumed to be uniform across slices. But
starting with Cannonlake, slices can be asymmetric (for example slice0
has different number of subslices as slice1+). This change stores all
subslices masks for all slices rather than having a single mask that
applies to all slices.
v2: Rework how we store total numbers in sseu_dev_info (Tvrtko)
Fix CHV eu masks, was reading disabled as enabled (Tvrtko)
Readability changes (Tvrtko)
Add EU index helper (Tvrtko)
v3: Turn ALIGN(v, 8) / 8 into DIV_ROUND_UP(v, BITS_PER_BYTE) (Tvrtko)
Reuse sseu_eu_idx() for setting eu_mask on CHV (Tvrtko)
Reformat debug prints for subslices (Tvrtko)
v4: Change eu_mask helper into sseu_set_eus() (Tvrtko)

through a new ioctl, there is no reason we can't display it in a human
readable fashion through debugfs.

There are a number of information that are readable from hardware
registers and that we would like to make accessible to userspace. One
particular example is the topology of the execution units (how are
execution units grouped in subslices and slices and also which ones
have been fused off for die recovery).
At the moment the GET_PARAM ioctl covers some basic needs, but
generally is only able to return a single value for each defined
parameter. This is a bit problematic with topology descriptions which
are array/maps of available units.
This change introduces a new ioctl that can deal with requests to fill
structures of potentially variable lengths. The user is expected fill
a query with length fields set at 0 on the first call, the kernel then
sets the length fields to the their expected values. A second call to
the kernel with length fields at their expected values will trigger a
copy of the data to the pointed memory locations.
The scope of this uAPI is only to provide information to userspace,
not to allow configuration of the device.
v2: Simplify dispatcher code iteration (Tvrtko)
Tweak uapi drm_i915_query_item structure (Tvrtko)
v3: Rename pad fields into flags (Chris)
Return error on flags field != 0 (Chris)
Only copy length back to userspace in drm_i915_query_item (Chris)

With the introduction of asymmetric slices in CNL, we cannot rely on
the previous SUBSLICE_MASK getparam to tell userspace what subslices
are available. Here we introduce a more detailed way of querying the
Gen's GPU topology that doesn't aggregate numbers.
This is essential for monitoring parts of the GPU with the OA unit,
because counters need to be normalized to the number of
EUs/subslices/slices. The current aggregated numbers like EU_TOTAL do
not gives us sufficient information.
As a bonus we can draw representations of the GPU :

v2: Rename uapi struct s/_mask/_info/ (Tvrtko)
Report max_slice/subslice/eus_per_subslice rather than strides (Tvrtko)
Add uapi macros to read data from *_info structs (Tvrtko)
v3: Use !!(v & DRM_I915_BIT()) for uapi macros instead of custom shifts (Tvrtko)
v4: factorize query item writting (Tvrtko)
tweak uapi struct/define names (Tvrtko)
v5: Replace ALIGN() macro (Chris)

Need to update the macro names in comments.
It would probably also be good to separately spell out in a comments
what is the bit-ordering in the returned data - bit0 =
slice0/subslice0/eu0, etc, or something like that.

I still can't believe Tvrtko hasn't asked this to become an function
pointer array. Tvrtko, I presume you've looked at how engine-info may
fit into this? And engine-stats? And have suggestions for making adding
new queries easier. Or are you happy as is?

I was happy with the switch for now. Was expecting someone would
complain on the whole idea anyway. Maybe I was too pessimistic. :)
As for the engine-info, I couldn't think of any reasons why this
framework wouldn't work for it. I'd put input parameters into the query
blobs.
Engine-stats I had no plans to expose here. You think it would be
useful? Main issue would be that we'd need commands to enable/disable
and not just queries. Unless some magic to auto-enable on first query
and drop after some timeout.. thinking to far ahead.
Regards,
Tvrtko
