2020-07-08drm/i915/sseu: Move sseu_info under gt_infoVenkata Sandeep Dhanalakota
SSEUs are a GT capability, so track them under gt_info.

2020-06-22drm/i915/params: switch to device specific parametersJani Nikula
Start using device specific parameters instead of module parameters for most things. The module parameters become the immutable initial values for i915 parameters. The device specific parameters in i915->params start life as a copy of i915_modparams. Any later changes are only reflected in the debugfs. The stragglers are: * i915.force_probe and i915.modeset. Needed before dev_priv is available. This is fine because the parameters are read-only and never modified. * i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and I915_STATE_WARN_ON would result in massive and ugly churn. This is handled by not exposing the parameter via debugfs, and leaving the parameter writable in sysfs. This may be fixed up in follow-up work. * i915.inject_probe_failure. Only makes sense in terms of the module, not the device. This is handled by not exposing the parameter via debugfs. v2: Fix uc i915 lookup code (Michał Winiarski) Cc: Juha-Pekka Heikkilä <juha-pekka.heikkila@intel.com> Cc: Venkata Sandeep Dhanalakota <venkata.s.dhanalakota@intel.com> Cc: Michał Winiarski <michal.winiarski@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Acked-by: Michał Winiarski <michal.winiarski@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20200618150402.14022-1-jani.nikula@intel.com
2020-05-14drm/i915: Store CS timestamp frequency in HzVille Syrjälä
kHz isn't accurate enough for storing the CS timestamp frequency on some of the platforms. Store the value in Hz instead.

2019-12-04drm/i915: Introduce DRM_I915_GEM_MMAP_OFFSETAbdiel Janulgue
This is really just an alias of mmap_gtt. The 'mmap offset' nomenclature comes from the value returned by this ioctl which is the offset into the device fd which userpace uses with mmap(2). mmap_gtt was our initial mmap_offset implementation, this extends our CPU mmap support to allow additional fault handlers that depends on the object's backing pages. Note that we multiplex mmap_gtt and mmap_offset through the same ioctl, and use the zero extending behaviour of drm to differentiate between them, when we inspect the flags. To support multiple mmap types on an object we need to support multiple mmap_offsets for an object (each offset in the global device address space corresponding to a unique instance of the object for a file + mmap type). As we drop the simplified drm core idea of a single mmap_offset, we need to provide replacement hooks for the dumb mmap interface as well.

2019-11-14Backmerge i915 security patches from commit 'ea0b163b13ff' into drm-nextDave Airlie
This backmerges the branch that ended up in Linus' tree. It removes all the changes for the rc6 patches from Linus' tree in favour of a patch that is based on a large refactor that occured. Otherwise it all looks good. Signed-off-by: Dave Airlie <airlied@redhat.com>
2019-11-05drm/i915: Disable Secure Batches for gen6+Jon Bloomfield
Retroactively stop reporting support for secure batches through the api for gen6+ so that older binaries trigger the fallback path instead. Older binaries use secure batches pre gen6 to access resources that are not available to normal usermode processes. However, all known userspace explicitly checks for HAS_SECURE_BATCHES before relying on the secure batch feature. Since there are no known binaries relying on this for newer gens we can kill secure batches from gen6, via I915_PARAM_HAS_SECURE_BATCHES. v2: rebase (Mika) v3: rebase (Mika) Signed-off-by: Jon Bloomfield <jon.bloomfield@intel.com> Cc: Tony Luck <tony.luck@intel.com> Cc: Dave Airlie <airlied@redhat.com> Cc: Takashi Iwai <tiwai@suse.de> Cc: Tyler Hicks <tyhicks@canonical.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Chris Wilson <chris.p.wilson@intel.com>
