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 Note this is the second iteration of an original patch to implement the same. There are a couple of minor code changes based on changes since the first series was posted. Additionally, the original patch has been split into several smaller patches with more isolated changes based on review feedback in that first series. Link to the original series: https://patchwork.freedesktop.org/series/59742/ v2: Fix 32-bit build v3: Fix typo in haswell sseu info routine and fix SSEU workaround print v4: Merge patch to HSW in previous revision with patch to set subslice_mask for each platform and address feedback from Chris v5: No changes in code. Resending due to unrelated failures - confirmed no failures with trybot. v6: Minor change in intel_workarounds.c to use the new helper function Stuart Summers (9): drm/i915: Use variable for debugfs device status drm/i915: Add function to set SSEU info per platform drm/i915: Add subslice stride runtime parameter drm/i915: Add EU stride runtime parameter drm/i915: Add function to set subslices drm/i915: Add function to determine if a slice has a subslice drm/i915: Refactor instdone loops on new subslice functions drm/i915: Add new function to copy subslices for a slice drm/i915: Expand subslice mask drivers/gpu/drm/i915/gt/intel_engine_cs.c | 3 +- drivers/gpu/drm/i915/gt/intel_engine_types.h | 31 +++-- drivers/gpu/drm/i915/gt/intel_hangcheck.c | 3 +- drivers/gpu/drm/i915/gt/intel_sseu.c | 48 +++++++- drivers/gpu/drm/i915/gt/intel_sseu.h | 24 +++- drivers/gpu/drm/i915/gt/intel_workarounds.c | 5 +- drivers/gpu/drm/i915/i915_debugfs.c | 49 +++++--- drivers/gpu/drm/i915/i915_gpu_error.c | 5 +- drivers/gpu/drm/i915/i915_query.c | 10 +- drivers/gpu/drm/i915/intel_device_info.c | 122 +++++++++---------- 10 files changed, 186 insertions(+), 114 deletions(-)
