Until Icelake, each engine had its own set of 64 MOCS registers. In order to simplify, Tigerlake moves to only 64 Global MOCS registers, which are no longer part of the engine context. Since these registers are now global, they also only need to be initialized once. >From Gen12 onwards, MOCS must specify the target cache (3:2) and LRU management (5:4) fields and cannot be programmed to 'use the value from Private PAT', because these fields are no longer part of the PPAT. Also cacheability control (1:0) field has changed, 00 no longer means 'use controls from page table', but uncacheable (UC). v2 (Lucas): - Move the changes to the fault registers to a separate commit - the old ones overlap with the range used by the new global MOCS (requested by Daniele) v3 (Lucas): - Clarify comment about setting the unused entries to the same value of index 0, that is the invalid entry (requested by Daniele) - Move changes to DONE_REG and ERROR_GEN6 to a separate commit (requested by Daniele) Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Signed-off-by: NMichel Thierry <michel.thierry@intel.com> Signed-off-by: NTvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: NLucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: NTomasz Lis <tomasz.lis@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190730180407.5993-5-lucas.demarchi@intel.com

Some platforms may have Modular FIA. If Modular FIA is used in the SOC, then Display Driver will access the additional instances of FIA based on pre-assigned offset in GTTMADDR space. Each Modular FIA instance has its own IOSF Sideband Port ID and it houses only 2 Type-C Port. In SOC that has more than two Type-C Ports, there are multiple instances of Modular FIA. Gunit will need to use different destination ID when it access different pair of Type-C Port. The DFLEXDPSP register has Modular FIA bit starting on Tiger Lake. If Modular FIA is used in the SOC, this register bit exists in all the instances of Modular FIA. IOM FW is required to program only the MF bit in first FIA instance that houses the Type-C Port 0 and Port 1, for Display Driver to read from. v2 (Lucas): - Move all accesses to FIA to be contained in intel_tc.c, along with display_fia that is now called tc_phy_fia - Save the fia instance number on intel_digital_port, so we don't have to query if modular FIA is used on every access v3 (Lucas): Make function static v4 (Lucas): Move enum phy_fia to the header and use it in intel_digital_port (suggested by Ville) v5 (Lucas): Add comment about the mapping between FIA and TC port (suggested by Stuart) Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: NAnusha Srivatsa <anusha.srivatsa@intel.com> Signed-off-by: NLucas De Marchi <lucas.demarchi@intel.com> Acked-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: NStuart Summers <stuart.summers@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190712055706.12143-2-lucas.demarchi@intel.com

The i915.alpha_support module parameter has caused some confusion along the way. Add new i915.force_probe parameter to specify PCI IDs of devices to probe, when the devices are recognized but not automatically probed by the driver. The name is intended to reflect what the parameter effectively does, avoiding any overloaded semantics of "alpha" and "support". The parameter supports "" to disable, "<pci-id>,[<pci-id>,...]" to enable force probe for one or more devices, and "*" to enable force probe for all known devices. Also add new CONFIG_DRM_I915_FORCE_PROBE config option to replace the DRM_I915_ALPHA_SUPPORT option. This defaults to "*" if DRM_I915_ALPHA_SUPPORT=y. Instead of replacing i915.alpha_support immediately, let the two coexist for a while, with a deprecation message, for a transition period.

Concept of a sub-platform already exist in our code (like ULX and ULT platform variants and similar),implemented via the macros which check a list of device ids to determine a match. With this patch we consolidate device ids checking into a single function called during early driver load. A few low bits in the platform mask are reserved for sub-platform identification and defined as a per-platform namespace. At the same time it future proofs the platform_mask handling by preparing the code for easy extending, and tidies the very verbose WARN strings generated when IS_PLATFORM macros are embedded into a WARN type statements. v2: Fixed IS_SUBPLATFORM. Updated commit msg. v3: Chris was right, there is an ordering problem. v4: * Catch-up with new sub-platforms. * Rebase for RUNTIME_INFO. * Drop subplatform mask union tricks and convert platform_mask to an array for extensibility. v5: * Fix subplatform check. * Protect against forgetting to expand subplatform bits. * Remove platform enum tallying. * Add subplatform to error state. (Chris) * Drop macros and just use static inlines. * Remove redundant IRONLAKE_M. (Ville) v6: * Split out Ironlake change. * Optimize subplatform check. * Use __always_inline.

Use of the new DRM_COLOR_LUT_NON_DECREASING test was a bit over-zealous; it doesn't actually need to be applied to the degamma on "bdw-style" platforms. Likewise, we overlooked the fact that CHV should have that test applied to the gamma LUT as well as the degamma LUT. Rather than adding more complicated platform checking to intel_color_check(), let's just store the appropriate set of LUT validation flags for each platform in the intel_device_info structure. v2: - Shuffle around LUT size tests so that the hardware-specific tests won't be applied to legacy gamma tables. (Ville) - Add a debug message so that it will be easier to understand why an atomic transaction involving incorrectly-sized LUT's got rejected by the driver. v3: - Switch size_t's to int's.

The device info offset arrays for unevenly spaced register offsets is great for widely used registers. However, the palette registers are only used in one function, i9xx_load_luts_internal(), and only for GMCH platforms, wasting device info. Replace palette_offsets with _PICK() in palette register definition. While the use of _PICK() does not check for pipe C existence, neither does the current offset array usage, and leads to bogus address when pipe C is passed to PALETTE() on non-CHV. Using _PICK() at least leads to a sensible register offset, just non-existing on non-CHV. Either way, this shouldn't happen anyway. Remove unused old palette macros while at it.

After disabling resource streamer on ICL (due to it actually not existing there), I got feedback that there have been some experimental patches for mesa to use RS years ago, but nothing ever landed or shipped because there was no performance improvement. This removes it from kernel keeping the uapi defines around for compatibility. v2: - re-add the inadvertent removal of CTX_CTRL_INHIBIT_SYN_CTX_SWITCH - don't bother trying to document removed params on uapi header: applications should know that from the query. (from Chris) v3: - disable CTX_CTRL_RS_CTX_ENABLE istead of removing it - reword commit message after Daniele confirmed no performance regression on his machine - reword commit message to make clear RS is being removed due to never been used v4: - move I915_EXEC_RESOURCE_STREAMER to __I915_EXEC_ILLEGAL_FLAGS so the check on ioctl() is made much earlier by i915_gem_check_execbuffer() (suggested by Tvrtko) Signed-off-by: NLucas De Marchi <lucas.demarchi@intel.com> Acked-by: NDaniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Reviewed-by: NTvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20180803232443.17193-1-lucas.demarchi@intel.com

Not all chipsets have an internal buffer delaying the visibility of writes via the GGTT being visible by other physical paths, but we use a very heavy workaround for all. We only need to apply that workarounds to the chipsets we know suffer from the delay and the resulting coherency issue. Similarly, the same inconsistent coherency fouls up our ABI promise that a write into a mmap_gtt is immediately visible to others. Since the HW has made that a lie, let userspace know when that contract is broken. (Not that userspace would want to use mmap_gtt on those chipsets for other performance reasons...)

This patch adds support to detect ICL, slice, subslice and EU fuse settings. Add addresses for ICL 11 slice, subslice and EU fuses registers. These register addresses are the same as previous platforms but the format and / or the meaning of the information is different. Therefore Gen11 defines for these registers are added.

In Gen11, the Video Decode engines (aka VDBOX, aka VCS, aka BSD) and the Video Enhancement engines (aka VEBOX, aka VECS) could be fused off. Also, each VDBOX and VEBOX has its own power well, which only exist if the related engine exists in the HW. Unfortunately, we have a Catch-22 situation going on: we need the blitter forcewake to read the register with the fuse info, but we cannot initialize the forcewake domains without knowin about the engines present in the HW. We workaround this problem by allowing the initialization of all forcewake domains and then pruning the fused off ones, as per the fuse information.
