drm/i915: avoid including intel_drv.h via i915_drv.h->i915_trace.h

2019-08-07T09:43:14Z

Disentangle i915_drv.h from intel_drv.h, which gets included via i915_trace.h. This necessitates including i915_trace.h wherever it's needed.

drm/i915: Propagate "_release" function name suffix down

2019-07-12T12:05:05Z

Replace mixed "_fini"/"_cleanup"/"_cleanup_hw" suffixes found in names of functions called from i915_driver_release() with "_release" suffix consistently. This provides better code readability, especially helpful when trying to work out which phase the code is in. Functions names starting with "i915_driver_", i.e., those defined in drivers/gpu/dri/i915/i915_drv.c, just have their "cleanup" or "fini" parts of their names replaced with the "_release" suffix, while names of functions coming from other source files have been suffixed with "_driver_release" to avoid ambiguity with other possible .release entry points. v2: early_probe pairs better with late_release (Chris) v3: fix typo in commit message (Joonas) Suggested-by: Chris Wilson Signed-off-by: Janusz Krzysztofik Reviewed-by: Chris Wilson Reviewed-by: Joonas Lahtinen Signed-off-by: Chris Wilson Link: https://patchwork.freedesktop.org/patch/msgid/20190712112429.740-5-janusz.krzysztofik@linux.intel.com

drm/i915: Fix memleak in runtime wakeref tracking

2019-07-02T15:00:20Z

If we untrack wakerefs, the actual count may reach zero. However the krealloced owners array is still there and needs to be taken care of. Free the owners unconditionally to fix the leak.

drm/i915: move and rename i915_runtime_pm

2019-06-14T14:58:33Z

Asserts aside, all the code working on this structure is in intel_runtime_pm.c and uses the intel_ prefix, so move the structure to intel_runtime_pm.h and adopt the same prefix. Since all the asserts are now working on the runtime_pm structure, bring them across as well. v2: drop unneeded include (Chris), don't rename debugfs, rebase Signed-off-by: Daniele Ceraolo Spurio Cc: Chris Wilson Cc: Imre Deak Reviewed-by: Chris Wilson Acked-by: Imre Deak Signed-off-by: Chris Wilson Link: https://patchwork.freedesktop.org/patch/msgid/20190613232156.34940-5-daniele.ceraolospurio@intel.com

drm/i915: extract intel_display_power.h/c from intel_runtime_pm.h/c

2019-06-04T07:32:48Z

Keep all the device-level PM management in intel_runtime_pm.h/c and move all the display specific bits into their own file. Also add the new header to Makefile.header-test. Apart from the giant code move, the only difference is with the intel_runtime__raw() functions, which are now exposed in the header. The _put() version is also not conditionally compiled anymore since it is ok to always pass the wakeref taken from the _get() to __intel_runtime_pm_put (it is -1 if tracking is disabled).
