2020-09-30drm/i915/gem: Serialise debugfs i915_gem_objects with ctx->mutexChris Wilson1-0/+2
Since the debugfs may peek into the GEM contexts as the corresponding client/fd is being closed, we may try and follow a dangling pointer. However, the context closure itself is serialised with the ctx->mutex, so if we hold that mutex as we inspect the state coupled in the context, we know the pointers within the context are stable and will remain valid as we inspect their tables.

2020-06-30drm/i915: Skip stale object handle for debugfs per-file-statsChris Wilson1-1/+1
As we close a handle GEM object, we update the drm_file's idr with an error^W NULL pointer to indicate the in-progress closure, and finally removing it. If we read the idr directly, we may then see an invalid object pointer, and in our debugfs per_file_stats() we therefore need to protect against the entry being invalid.

2020-06-22drm/i915/params: switch to device specific parametersJani Nikula1-1/+1
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 <[email protected]> Cc: Venkata Sandeep Dhanalakota <[email protected]> Cc: Michał Winiarski <[email protected]> Reviewed-by: Rodrigo Vivi <[email protected]> Acked-by: Michał Winiarski <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected]

2020-04-30drm/i915/gt: Move the batch buffer pool from the engine to the gtChris Wilson1-0/+4
Since the introduction of 'soft-rc6', we aim to park the device quickly and that results in frequent idling of the whole device. Currently upon idling we free the batch buffer pool, and so this renders the cache ineffective for many workloads. If we want to have an effective cache of recently allocated buffers available for reuse, we need to decouple that cache from the engine powermanagement and make it timer based. As there is no reason then to keep it within the engine (where it once made retirement order easier to track), we can move it up the hierarchy to the owner of the memory allocations. v2: Hook up to debugfs/drop_caches to clear the cache on demand.

2020-04-02drm/i915/gem: Drop cached obj->bind_countChris Wilson1-5/+2
We cached the number of vma bound to the object in order to speed up shrinker decisions. This has been superseded by being more proactive in removing objects we cannot shrink from the shrinker lists, and so we can drop the clumsy attempt at atomically counting the bind count and comparing it to the number of pinned mappings of the object. This will only get more clumsier with asynchronous binding and unbinding.

2020-01-15drm/i915/params: add i915 parameters to debugfsJani Nikula1-1/+3
Add a debugfs subdirectory i915_params with all the i915 module parameters. This is a first step, with lots of boilerplate, and not much benefit yet. This will result in a new device specific debugfs directory at /sys/kernel/debug/dri/<N>/i915_params duplicating the module specific sysfs directory at /sys/module/i915/parameters/. Going forward, all users of the parameters should use the debugfs, with the module parameters being phased out. Add debugfs permissions to I915_PARAMS_FOR_EACH(). This duplicates the mode with module parameter sysfs, but the goal is to make the module parameters read-only initial values for device specific parameters. 0 mode will bypass debugfs creation. Use it for verbose_state_checks which will need special attention in follow-up work.
