[ Upstream commit 7ee9b3e091 ]
The topology query helper advanced the user pointer by the size
of the pointer, not the size of the structure. This can misalign
the output blob and corrupt the following mask. Fix the increment
to use sizeof(*topo).
There is no issue currently, as sizeof(*topo) happens to be equal
to sizeof(topo) on 64-bit systems (both evaluate to 8 bytes).

The 'id' value updated by for_each_gt() is the uapi GT ID of the GTs
being iterated over, and may skip over values if a GT is not present on
the device. Use a separate iterator for GT list array assignments to

[ Upstream commit 9ab440a9d0 ]
On PTL platforms with media version 30.00, the fuse registers for
reporting L3 bank availability to the GT just read out as ~0 and do not
provide proper values. Xe does not use the L3 bank mask for anything
internally; it only passes the mask through to userspace via the GT
topology query.
Since we don't have any way to get the real L3 bank mask, we don't want
to pass garbage to userspace. Passing a zeroed mask or a copy of the
primary GT's L3 bank mask would also be inaccurate and likely to cause
confusion for userspace. The best approach is to simply not include L3
in the list of masks returned by the topology query in cases where we
aren't able to provide a meaningful value. This won't change the
behavior for any existing platforms (where we can always obtain L3 masks
successfully for all GTs), it will only prevent us from mis-reporting
bad information on upcoming platform(s).
There's a good chance this will become a formal workaround in the
future, but for now we don't have a lineage number so "no_media_l3" is
used in place of a lineage as the OOB workaround descriptor.
v2:
- Re-calculate query size to properly match data returned. (Gustavo)
- Update kerneldoc to clarify that the L3bank mask may not be included
in the query results if the hardware doesn't make it available.

Starting with Xe2 the timestamp is a full 64 bit counter, contrary to
the 36 bit that was available before. Although 36 should be sufficient
for any reasonable delta calculation (for Xe2, of about 30min), it's
surprising to userspace to get something truncated. Also if the
timestamp being compared to is coming from the GPU and the application
is not careful enough to apply the width there, a delta calculation
would be wrong.
Extend it to full 64-bits starting with Xe2.
v2: Expand width=64 to media gt, as it's just a wrong tagging in the
spec - empirical tests show it goes beyond 36 bits and match the engines
for the main gt

PVC, Xe2 and later platforms have 16-wide EUs. We were implicitly
reporting for PVC the number of 16-wide EUs without giving userspace any
hint that they were different than for other platforms. Xe2 and later
also have 16-wide, but in those cases the reported number would
correspond to the 8-wide count.
To avoid confusion and make sure the right number is used by userspace
depending on the platform, add a new item to the topology query and drop
the one that is not available. The new mask reported for both PVC and
Xe2 should now match the numbers reported via hwconfig.

A force_wake_get failure means that the HW might not be awake for the
access we're doing; this can lead to an immediate error or it can be a
more subtle problem (e.g. a register read might return an incorrect
value that is still valid, leading the driver to make a wrong choice
instead of flagging an error).
We avoid an error from the force_wake function because callers might
handle or tolerate the error, but this only works if all callers
are checking the error code. The majority already do, but a few are not.
These are mainly falling into 3 categories, which are each handled
differently:
1) error capture: in this case we want to continue the capture, but we
log an info message in dmesg to notify the user that the capture
might have incorrect data.
2) ioctl: in this case we return a -EIO error to userspace
3) unabortable actions: these are scenarios where we can't simply abort
and retry and so it's better to just try it anyway because there is a
chance the HW is awake even with the failure. In this case we throw a
warning so we know there was a forcewake problem if something fails
down the line.

For modern platforms (MTL and later), both kernel and userspace drivers
are expected to apply GT programming and workarounds based on the IP
version and stepping self-reported by the GT hardware via the GMD_ID
registers. Since userspace drivers can't access these registers
directly, pass along the version and stepping information via the GT
list query. Note that the new query fields will remain 0's when running
on pre-GMD_ID platforms. Userspace is expected to continue using PCI
devid / revid on those older platforms.
Although the hardware also has a GMD_ID register for display
version/stepping, that value is intentionally *not* included anywhere in
the Xe uapi. Display userspace should be using platform-agnostic APIs
and auto-detecting platform capabilities rather than matching specific
IP versions.

We have at least 2 future features(OA and future media engines
capabilities) that will require Xe to provide more information about
engines to UMDs.
But this information should not just be added to
drm_xe_engine_class_instance for a couple of reasons:
- drm_xe_engine_class_instance is used as input to other structs/uAPIs
and those uAPIs don't care about any of these future new engine fields
- those new fields are useless information after initialization for
some UMDs, so it should not need to carry that around

Mostly the same as i915. We add a new hint for userspace to force an
object into the mappable part of vram.
We also need to tell userspace how large the mappable part is. In Vulkan
for example, there will be two vram heaps for small-bar systems. And
here the size of each heap needs to be known. Likewise the used/avail
tracking needs to account for the mappable part.
We also limit the available tracking going forward, such that we limit
to privileged users only, since these values are system wide and are
technically considered an info leak.

- s/NEEDS_CPU_ACCESS/NEEDS_VISIBLE_VRAM/ in the uapi. We also no
longer require smem as an extra placement. This is more flexible,
and lets us use this for clear-color surfaces, since we need CPU access
there but we don't want to attach smem, since that effectively disables
CCS from kernel pov.

v6:
- Without perfmon_capable() it likely makes more sense to report as
zero, instead of reporting as used == total size. This should give
similar behaviour as i915 which rather tracks free instead of used.
- Only enforce NEEDS_VISIBLE_VRAM on rc_ccs_cc_plane surfaces when the
device is actually small-bar.
