5e822e44ce drm/i915/gvt: Fix guest boot warning
Simulate MIA core in reset status once GUC engine is reset.

v2: 1. use vgpu_vreg_t() function,
    2. clear MIA_IN_RESET after reading. (Zhenyu)
v3: add comments. (Zhenyu)

9f674c8117 drm/i915/gvt: Pin vgpu dma address before using
Dma-buf display uses the vgpu dma address saved in the guest part GGTT
table which is updated by vCPU thread. In host side, when the dma
address is used by qemu ui thread, gvt-g must make sure the dma address
is validated before letting it go to the HW. Invalid guest dma address
will easily cause DMA fault and make GPU hang.

v2: Rebase

4fc0a3ca72 drm/i915/gvt: set guest display buffer as readonly
We shouldn't allow write for exposed guest display buffer which
doesn't make sense. So explicitly set read only flag for display
dmabuf allocated object.

83faaf074e drm/i915/gvt: Stop initializing pvinfo through reading mmio
The region of pvinfo is reserved for communication between a VMM and
the GPU driver executing on a virtual machine. HW doesn't have any
backing mmio store support for the pvinfo region, thus accessing to
this range through MMIO read/write from host side is forbidden which
is regarded as unclaimed register access.

This patch leaves pvinfo range be initialized with zero.

a50134b198 drm/i915: Make for_each_engine_masked work on intel_gt
Medium term goal is to eliminate the i915->engine[] array and to get there
we have recently introduced equivalent array in intel_gt. Now we need to
migrate the code further towards this state.

This next step is to eliminate usage of i915->engines[] from the
for_each_engine_masked iterator.

For this to work we also need to use engine->id as index when populating
the gt->engine[] array and adjust the default engine set indexing to use
engine->legacy_idx instead of assuming gt->engines[] indexing.

v2:
  * Populate gt->engine[] earlier.
  * Check that we don't duplicate engine->legacy_idx

v3:
  * Work around the initialization order issue between default_engines()
    and intel_engines_driver_register() which sets engine->legacy_idx for
    now. It will be fixed properly later.

v4:
  * Merge with forgotten v2.5.

2935ed5339 drm/i915: Remove logical HW ID
With the introduction of ctx->engines[] we allow multiple logical
contexts to be used on the same engine (e.g. with virtual engines).
According to bspec, aach logical context requires a unique tag in order
for context-switching to occur correctly between them. [Simple
experiments show that it is not so easy to trick the HW into performing
a lite-restore with matching logical IDs, though my memory from early
Broadwell experiments do suggest that it should be generating
lite-restores.]

We only need to keep a unique tag for the active lifetime of the
context, and for as long as we need to identify that context. The HW
uses the tag to determine if it should use a lite-restore (why not the
LRCA?) and passes the tag back for various status identifies. The only
status we need to track is for OA, so when using perf, we assign the
specific context a unique tag.

v2: Calculate required number of tags to fill ELSP.

b1e3177bd1 drm/i915: Coordinate i915_active with its own mutex
Forgo the struct_mutex serialisation for i915_active, and interpose its
own mutex handling for active/retire.

This is a multi-layered sleight-of-hand. First, we had to ensure that no
active/retire callbacks accidentally inverted the mutex ordering rules,
nor assumed that they were themselves serialised by struct_mutex. More
challenging though, is the rule over updating elements of the active
rbtree. Instead of the whole i915_active now being serialised by
struct_mutex, allocations/rotations of the tree are serialised by the
i915_active.mutex and individual nodes are serialised by the caller
using the i915_timeline.mutex (we need to use nested spinlocks to
interact with the dma_fence callback lists).

The pain point here is that instead of a single mutex around execbuf, we
now have to take a mutex for active tracker (one for each vma, context,
etc) and a couple of spinlocks for each fence update. The improvement in
fine grained locking allowing for multiple concurrent clients
(eventually!) should be worth it in typical loads.

v2: Add some comments that barely elucidate anything :(

2850748ef8 drm/i915: Pull i915_vma_pin under the vm->mutex
Replace the struct_mutex requirement for pinning the i915_vma with the
local vm->mutex instead. Note that the vm->mutex is tainted by the
shrinker (we require unbinding from inside fs-reclaim) and so we cannot
allocate while holding that mutex. Instead we have to preallocate
workers to do allocate and apply the PTE updates after we have we
reserved their slot in the drm_mm (using fences to order the PTE writes
with the GPU work and with later unbind).

In adding the asynchronous vma binding, one subtle requirement is to
avoid coupling the binding fence into the backing object->resv. That is
the asynchronous binding only applies to the vma timeline itself and not
to the pages as that is a more global timeline (the binding of one vma
does not need to be ordered with another vma, nor does the implicit GEM
fencing depend on a vma, only on writes to the backing store). Keeping
the vma binding distinct from the backing store timelines is verified by
a number of async gem_exec_fence and gem_exec_schedule tests. The way we
do this is quite simple, we keep the fence for the vma binding separate
and only wait on it as required, and never add it to the obj->resv
itself.

Another consequence in reducing the locking around the vma is the
destruction of the vma is no longer globally serialised by struct_mutex.
A natural solution would be to add a kref to i915_vma, but that requires
decoupling the reference cycles, possibly by introducing a new
i915_mm_pages object that is own by both obj->mm and vma->pages.
However, we have not taken that route due to the overshadowing lmem/ttm
discussions, and instead play a series of complicated games with
trylocks to (hopefully) ensure that only one destruction path is called!

v2: Add some commentary, and some helpers to reduce patch churn.

4ab4fa1032 drm/i915/psr: Make PSR registers relative to transcoders
PSR registers are a mess, some have the full address while others just
have the additional offset from psr_mmio_base.

For BDW+ psr_mmio_base is nothing more than TRANSCODER_EDP_OFFSET +
0x800 and using it makes more difficult for people with an PSR
register address or PSR register name from from BSpec as i915 also
don't match the BSpec names.
For HSW psr_mmio_base is _DDI_BUF_CTL_A + 0x800 and PSR registers are
only available in DDIA.

Other reason to make relative to transcoder is that since BDW every
transcoder have PSR registers, so in theory it should be possible to
have PSR enabled in a non-eDP transcoder.

So for BDW+ we can use _TRANS2() to get the register offset of any
PSR register in any transcoder while for HSW we have _HSW_PSR_ADJ
that will calculate the register offset for the single PSR instance,
noting that we are already guarded about trying to enable PSR in other
port than DDIA on HSW by the 'if (dig_port->base.port != PORT_A)' in
intel_psr_compute_config(), this check should only be valid for HSW
and will be changed in future.
PSR2 registers and PSR_EVENT was added after Haswell so that is why
_PSR_ADJ() is not used in some macros.

The only registers that can not be relative to transcoder are
PSR_IMR and PSR_IIR that are not relative to anything, so keeping it
hardcoded. That changed for TGL but it will be handled in another
patch.

Also removing BDW_EDP_PSR_BASE from GVT because it is not used as it
is the only PSR register that GVT have.

v5:
- Macros changed to be more explicit about HSW (Dhinakaran)
- Squashed with the patch that added the tran parameter to the
macros (Dhinakaran)

v6:
- Checking for interruption errors after module reload in the
transcoder that will be used (Dhinakaran)
- Using lowercase to the registers offsets

v7:
- Removing IS_HASWELL() from registers macros(Jani)

8cfbca7848 drm/i915/gvt: factor out tlb and mocs register offset table
Factor out tlb and mocs register offset table to fix the issues reported
by klocwork, #512 and #550. Mostly, the reason why the klocwork reports
these problems is because there can be possbilities for platforms, which
have more rings than the ring offset table, to take the dirty data from
the stack as the register offset. It results to a random HW register
offset writting in this scenairo when doing context switch between vGPUs.

After the factoring, the ring offset table of TLB and MOCS should be per
platform.

v2:

- Enable TLB register switch for GEN8. (Zhenyu)

f8871ec8fc drm/i915/gvt: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Because there is no need to check these functions, a number of local
functions can be made to return void to simplify things as nothing can
fail.

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.

So, replace the following form:

sizeof(*sparse) + (nr_areas * sizeof(*sparse->areas)

with:

struct_size(sparse, areas, sparse->nr_areas)

and so on...

Also, notice that variable size is unnecessary, hence it is removed.

a37f08a882 drm/i915/perf: Refactor oa object to better manage resources
The oa object manages the oa buffer and must be allocated when the user
intends to read performance counter snapshots. This can be achieved by
making the oa object part of the stream object which is allocated when a
stream is opened by the user.

Attributes in the oa object that are gen-specific are moved to the perf
object so that they can be initialized on driver load.

The split provides a better separation of the objects used in perf
implementation of i915 driver so that resources are allocated and
initialized only when needed.

4187414808 drm/i915/gvt: Adding ppgtt to GVT GEM context after shadow pdps settled.
Windows guest can't run after force-TDR with host log:
...
gvt: vgpu 1: workload shadow ppgtt isn't ready
gvt: vgpu 1: fail to dispatch workload, skip
...

The error is raised by set_context_ppgtt_from_shadow(), when it checks
and found the shadow_mm isn't marked as shadowed.

In work thread before each submission, a shadow_mm is set to shadowed in:
shadow_ppgtt_mm()
<-intel_vgpu_pin_mm()
<-prepare_workload()
<-dispatch_workload()
<-workload_thread()
However checking whether or not shadow_mm is shadowed is prior to it:
set_context_ppgtt_from_shadow()
<-dispatch_workload()
<-workload_thread()

In normal case, create workload will check the existence of shadow_mm,
if not it will create a new one and marked as shadowed. If already exist
it will reuse the old one. Since shadow_mm is reused, checking of shadowed
in set_context_ppgtt_from_shadow() actually always see the state set in
creation, but not the state set in intel_vgpu_pin_mm().

When force-TDR, all engines are reset, since it's not dmlr level, all
ppgtt_mm are invalidated but not destroyed. Invalidation will mark all
reused shadow_mm as not shadowed but still keeps in ppgtt_mm_list_head.
If workload submission phase those shadow_mm are reused with shadowed
not set, then set_context_ppgtt_from_shadow() will report error.

Pin for context after shadow_mm pinned and shadow pdps settled.

v2:
Move set_context_ppgtt_from_shadow() after prepare_workload(). (zhenyu)
v3:
Move set_context_ppgtt_from_shadow() after shadow pdps updated.(zhenyu)
