Currently, the subslice_mask runtime parameter is stored as an
array of subslices per slice. Expand the subslice mask array to
better match what is presented to userspace through the
I915_QUERY_TOPOLOGY_INFO ioctl. The index into this array is
then calculated:
slice * subslice stride + subslice index / 8
v2: Fix 32-bit build
v3: Use new helper function in SSEU workaround warning message
v4: Use GEM_BUG_ON to force developers to use valid SSEU configurations
per platform (Chris)

Add a subslice stride calculation when setting subslices. This
aligns more closely with the userspace expectation of the subslice
mask structure.
v2: Use local variable for subslice_mask on HSW and
clean up a few other subslice_mask local variable
changes
v3: Add GEM_BUG_ON for ss_stride to prevent array overflow (Chris)
Split main set function and refactors in intel_device_info.c
into separate patches (Chris)
v4: Reduce ss_stride size check when setting subslices per slice
based on actual expected max stride (Chris)
Move that GEM_BUG_ON check for the ss_stride out to the patch
which adds the ss_stride
v5: Use memcpy instead of looping through each stride index

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)

Most importantly per-process address spaces on GPUs that are capable of
providing proper isolation has finished baking. This is the base for
our softpin implementation, which allows us to support the texture
descriptor buffers used by GC7000 series GPUs without a major UAPI
extension/rework.
Shortlog of notable changes:
- code cleanup from Fabio
- fix performance counters on GC880 and GC2000 GPUs from Christian
- drmP.h header removal from Sam
- per process address space support on MMUv2 GPUs from me
- softpin support from me

We're not allowed to create new properties after device registration
so for MST connectors we need to either create the max_bpc property
earlier, or we reuse one we already have. Let's do the latter apporach
since the corresponding SST connector already has the prop and its
min/max are correct also for the MST connector.
The problem was highlighted by commit 4f5368b554 ("drm/kms:
Catch mode_object lifetime errors") which results in the following
spew:

When under severe stress for GTT mappable space, the LRU eviction model
falls off a cliff. We spend all our time scanning the much larger
non-mappable area searching for something within the mappable zone we can
evict. Turn this on its head by only using the full vma for the object if
it is already pinned in the mappable zone or there is sufficient *free*
space to accommodate it (prioritizing speedy reuse). If there is not,
immediately fall back to using small chunks (tilerow for GTT mmap, single
pages for pwrite/relocation) and using random eviction before doing a full
search.
