We may need to eliminate the crtc->index == pipe assumptions from the code to support arbitrary pipes being fused off. Start that by switching some bitmasks over to using pipe instead of the crtc index. Signed-off-by:

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) Signed-off-by:Stuart Summers <stuart.summers@intel.com> Reviewed-by:

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) Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Zhi Wang <zhi.a.wang@intel.com> Reviewed-by:

We can reduce the locking for fence registers from the dev->struct_mutex to a local mutex. We could introduce a mutex for the sole purpose of tracking the fence acquisition, except there is a little bit of overlap with the fault tracking, so use the i915_ggtt.mutex as it covers both. Signed-off-by:

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.

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.
