2022-06-08drm/i915: More PVC+DG2 workaroundsMatt Roper4-7/+23
A new PVC+DG2 workaround has appeared recently: - Wa_16015675438 And a couple existing DG2 workarounds have been extended to PVC: - Wa_14015795083 - Wa_18018781329 Note that Wa_16015675438 asks us to program a register that is in the 0x2xxx range typically associated with the RCS engine, even though PVC does not have an RCS. By default the GuC will think we've made a mistake and throw an exception when it sees this register on a CCS engine's save/restore list, so we need to pass an extra GuC control flag to tell it that this is expected and not a problem.

2022-06-08drm/i915/dg2: Correct DSS check for Wa_1308578152Matt Roper1-1/+1
When converting our DSS masks to bitmaps, we fumbled the condition used to check whether any DSS are present in the first gslice. Since intel_sseu_find_first_xehp_dss() returns a 0-based number, we need a >= condition rather than >.

2022-06-02drm/i915: Add extra registers to GPU error dumpStuart Summers1-0/+5
Our internal teams have identified a few additional engine registers that are worth inspecting in error state dumps during development & debug. Let's capture and print them as part of our error dump. For simplicity we'll just dump these registers on gen11 and beyond. Most of these registers have existed since earlier platforms (e.g., gen6 or gen7) but were initially introduced only for a subset of the platforms' engines; gen11 seems to be where they became available on all engines.

2022-06-02drm/i915/sseu: Disassociate internal subslice mask representation from uapiMatt Roper6-178/+232
As with EU masks, it's easier to store subslice/DSS masks internally in a format that's more natural for the driver to work with, and then only covert into the u8[] uapi form when the query ioctl is invoked. Since the hardware design changed significantly with Xe_HP, we'll use a union to choose between the old "hsw-style" subslice masks or the newer xehp mask. HSW-style masks will be stored in an array of u8's, indexed by slice (there's never more than 6 subslices per slice on older platforms). For Xe_HP and beyond where slices no longer exist, we only need a single bitmask. However we already know that this mask is eventually going to grow too large for a simple u64 to hold, so we'll represent it in a manner that can be operated on by the utilities in linux/bitmap.h. v2: - Fix typo: BIT(s) -> BIT(ss) in gen9_sseu_device_status() v3: - Eliminate sseu->ss_stride and just calculate the stride while specifically handling uapi. (Tvrtko) - Use BITMAP_BITS() macro to refer to size of masks rather than passing I915_MAX_SS_FUSE_BITS directly. (Tvrtko) - Report compute/geometry DSS masks separately when dumping Xe_HP SSEU info. (Tvrtko) - Restore dropped range checks to intel_sseu_has_subslice(). (Tvrtko) v4: - Make the bitmap size macro check the size of the .xehp field rather than the containing union. (Tvrtko) - Don't add GEM_BUG_ON() intel_sseu_has_subslice()'s check for whether slice or subslice ID exceed sseu->max_[sub]slices; various loops in the driver are expected to exceed these, so we should just silently return 'false.' v5: - Move XEHP_BITMAP_BITS() to the header so that we can also replace a usage of I915_MAX_SS_FUSE_BITS in one of the inline functions. (Bala) - Change the local variable in intel_slicemask_from_xehp_dssmask() from u16 to 'unsigned long' to make it a bit more future-proof.

2022-06-02drm/i915/sseu: Don't try to store EU mask internally in UAPI formatMatt Roper2-32/+66
Storing the EU mask internally in the same format the I915_QUERY topology queries use makes the final copy_to_user() a bit simpler, but makes the rest of the driver's SSEU more complicated and harder to follow. Let's switch to an internal representation that's more natural: Xe_HP platforms will be a simple array of u16 masks, whereas pre-Xe_HP platforms will be a two-dimensional array, indexed by [slice][subslice]. We'll convert to the uapi format only when the query uapi is called. v2: - Drop has_common_ss_eumask. We waste some space repeating identical EU masks for every single DSS, but the code is simpler without it. (Tvrtko) v3: - Mask down EUs passed to sseu_set_eus at the callsite rather than inside the function. (Tvrtko) - Eliminate sseu->eu_stride and calculate it when needed.

2022-06-02drm/i915/sseu: Simplify gen11+ SSEU handlingMatt Roper1-40/+36
Although gen11 and gen12 architectures supported the concept of multiple slices, in practice all the platforms that were actually designed only had a single slice (i.e., note the parameters to 'intel_sseu_set_info' that we pass for each platform). We can simplify the code slightly by dropping the multi-slice logic from gen11+ platforms. v2: - Promote drm_dbg to drm_WARN_ON if the slice fuse register reports unexpected fusing.

2022-05-16i915/guc/reset: Make __guc_reset_context aware of guilty enginesUmesh Nerlige Ramappa5-12/+12
There are 2 ways an engine can get reset in i915 and the method of reset affects how KMD labels a context as guilty/innocent. (1) GuC initiated engine-reset: GuC resets a hung engine and notifies KMD. The context that hung on the engine is marked guilty and all other contexts are innocent. The innocent contexts are resubmitted. (2) GT based reset: When an engine heartbeat fails to tick, KMD initiates a gt/chip reset. All active contexts are marked as guilty and discarded. In order to correctly mark the contexts as guilty/innocent, pass a mask of engines that were reset to __guc_reset_context.
