Context Timestamp (CTX_TIMESTAMP) in the LRC accumulates the run ticks
of the context, but only gets updated when the context switches out. In
order to check how long a context has been active before it switches
out, two things are required:
(1) Determine if the context is running:
To do so, we program the WA BB to set an initial value for CTX_TIMESTAMP
in the LRC. The value chosen is 1 since 0 is the initial value when the
LRC is initialized. During a query, we just check for this value to
determine if the context is active. If the context switched out, it
would overwrite this location with the actual CTX_TIMESTAMP MMIO value.
Note that WA BB runs as the last part of the context restore, so reusing
this LRC location will not clobber anything.
(2) Calculate the time that the context has been active for:
The CTX_TIMESTAMP ticks only when the context is active. If a context is
active, we just use the CTX_TIMESTAMP MMIO as the new value of
utilization. While doing so, we need to read the CTX_TIMESTAMP MMIO
for the specific engine instance. Since we do not know which instance
the context is running on until it is scheduled, we also read the
ENGINE_ID MMIO in the WA BB and store it in the PPHSWP.
Using the above 2 instructions in a WA BB, capture active context
utilization.
v2: (Matt Brost)
- This breaks TDR, fix it by saving the CTX_TIMESTAMP register
"drm/xe: Save CTX_TIMESTAMP mmio value instead of LRC value"
- Drop tile from LRC if using gt
"drm/xe: Save the gt pointer in LRC and drop the tile"
v3:
- Remove helpers for bb_per_ctx_ptr (Matt)
- Add define for context active value (Matt)
- Use 64 bit CTX TIMESTAMP for platforms that support it. For platforms
that don't, live with the rare race. (Matt, Lucas)
- Convert engine id to hwe and get the MMIO value (Lucas)
- Correct commit message on when WA BB runs (Lucas)
v4:
- s/GRAPHICS_VER(...)/xe->info.has_64bit_timestamp/ (Matt)
- Drop support for active utilization on a VF (CI failure)
- In xe_lrc_init ensure the lrc value is 0 to begin with (CI regression)
v5:
- Minor checkpatch fix
- Squash into previous commit and make TDR use 32-bit time
- Update code comment to match commit msg

With the idea of having more pinned objects using the blitter engine
where possible, during suspend/resume, mark the pinned objects which
can be done during the late phase once submission/migration has been
setup. Start out simple with lrc and page-tables from userspace.
v2:
- s/early_restore/late_restore; early restore was way too bold with too
many places being impacted at once.
v3:
- Split late vs early into separate lists, to align with newly added
apply-to-pinned infra.
v4:
- Rebase.
v5:
- Make sure we restore the late phase kernel_bo_present in igpu.

The context of each engine starts with a 4k memory space for the
"Per-process HW status page" (PPHWSP). In xe_gt_lrc_size(), we have been
implicitly accounting for that page in the switch statement on the
engine class.
Since the PPHWSP is common to all engines, let's extract that into it's
own assignment. That makes the context structure more explicit in the
code and aligns better with the descriptions in Bspec.
Another advantage of keeping it separate is that now the sizes used in
the switch statement match the sizes we calculate engine-specific
context images, which have their own Bspec pages.

Userspace is required to mark a queue as using PXP to guarantee that the
PXP instructions will work. In addition to managing the PXP sessions,
when a PXP queue is created the driver will set the relevant bits in
its context control register.
On submission of a valid PXP queue, the driver will validate all
encrypted objects mapped to the VM to ensured they were encrypted with
the current key.
v2: Remove pxp_types include outside of PXP code (Jani), better comments
and code cleanup (John)
v3: split the internal PXP management to a separate patch for ease of
review. re-order ioctl checks to always return -EINVAL if parameters are
invalid, rebase on msix changes.

When we decide to kill a job, (from guc_exec_queue_timedout_job), we could
end up with 4 possible scenarios at this starting point of this decision:
1. the guc-captured register-dump is already there.
2. the driver is wedged.mode > 1, so GuC-engine-reset / GuC-err-capture
will not happen.
3. the user has started the driver in execlist-submission mode.
4. the guc-captured register-dump is not ready yet so we force GuC to kill
that context now, but:
A. we don't know yet if GuC will be successful on the engine-reset
and get the guc-err-capture, else kmd will do a manual reset later
OR B. guc will be successful and we will get a guc-err-capture
shortly.
So to accomdate the scenarios of 2 and 4A, we will need to do a manual KMD
capture first(which is not be reliable in guc-submission mode) and decide
later if we need to use that for the cases of 2 or 4A. So this flow is
part of the implementation for this patch.
Provide xe_guc_capture_get_reg_desc_list to get the register dscriptor
list.
Add manual capture by read from hw engine if GuC capture is not ready.
If it becomes ready at later time, GuC sourced data will be used.
Although there may only be a small delay between (1) the check for whether
guc-err-capture is available at the start of guc_exec_queue_timedout_job
and (2) the decision on using a valid guc-err-capture or manual-capture,
lets not take any chances and lock the matching node down so it doesn't
get re-claimed if GuC-Err-Capture subsystem is running out of pre-cached
nodes.

When using MSI-X, hw engines report interrupt status and source to engine
instance 0. For this scenario, in order to differentiate between the
engines, we need to pass different status/source pointers in the LRC.
The requirements on those pointers are:
- Interrupt status should be 4KiB aligned
- Interrupt source should be 64 bytes aligned
To accommodate this, we duplicate the current memirq page layout -
allocating a page for each engine instance and pass this page in the LRC.
Note that the same page can be reused for different engine types.
For example, an LRC executing on CCS #x will have pointers to page #x,
and an LRC executing on BCS #x will have the same pointers. Thus, to
locate the proper page, the pointer accessors were modified to receive
the hw engine.

Early in the development of Xe we identified an issue with SVG state
handling on DG2 and MTL (and later on Xe2 as well). In
commit 72ac304769 ("drm/xe: Emit SVG state on RCS during driver load
on DG2 and MTL") and commit fb24b858a2 ("drm/xe/xe2: Update SVG state
handling") we implemented our own workaround to prevent SVG state from
leaking from context A to context B in cases where context B never
issues a specific state setting.
The hardware teams have now created official workaround Wa_14019789679
to cover this issue. The workaround description only requires emitting
3DSTATE_MESH_CONTROL, since they believe that's the only SVG instruction
that would potentially remain unset by a context B, but still cause
notable issues if unwanted values were inherited from context A.
However since we already have a more extensive implementation that emits
the entire SVG state and prevents _any_ SVG state from unintentionally
leaking, we'll stick with our existing implementation just to be safe.

The flags stored in the BO grew over time without following
much a naming pattern. First of all, get rid of the _BIT suffix that was
banned from everywhere else due to the guideline in
drivers/gpu/drm/i915/i915_reg.h that xe kind of follows:
Define bits using ``REG_BIT(N)``. Do **not** add ``_BIT`` suffix to the name.
Here the flags aren't for a register, but it's good practice to keep it
consistent.
Second divergence on names is the use or not of "CREATE". This is
because most of the flags are passed to xe_bo_create*() family of
functions, changing its behavior. However, since the flags are also
stored in the bo itself and checked elsewhere in the code, it seems
better to just omit the CREATE part.
With those 2 guidelines, all the flags are given the form
XE_BO_FLAG_<FLAG_NAME> with the following commands:
git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i \
-e "s/XE_BO_\([_A-Z0-9]*\)_BIT/XE_BO_\1/g" \
-e 's/XE_BO_CREATE_/XE_BO_FLAG_/g'
git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i -r \
-e 's/XE_BO_(DEFER_BACKING|SCANOUT|FIXED_PLACEMENT|PAGETABLE|NEEDS_CPU_ACCESS|NEEDS_UC|INTERNAL_TEST|INTERNAL_64K|GGTT_INVALIDATE)/XE_BO_FLAG_\1/g'
And then the defines in drivers/gpu/drm/xe/xe_bo.h are adjusted to
follow the coding style.
