Hi all,
One of the things in the DRM TODO list ("Documentation/gpu/todo.rst") was to "use DRM_MODESET_LOCAL_ALL_* helpers instead of boilerplate". That's what this patch series is about.
You will find two types of changes here:
- Replacing "drm_modeset_lock_all_ctx()" (and surrounding boilerplate) with "DRM_MODESET_LOCK_ALL_BEGIN()/END()" in the remaining places (as it has already been done in previous commits such as b7ea04d2)
- Replacing "drm_modeset_lock_all()" with "DRM_MODESET_LOCK_ALL_BEGIN()/END()" in the remaining places (as it has already been done in previous commits such as 57037094)
Most of the changes are straight forward, except for a few cases in the "amd" and "i915" drivers where some extra dancing was needed to overcome the limitation that the DRM_MODESET_LOCK_ALL_BEGIN()/END() macros can only be used once inside the same function (the reason being that the macro expansion includes *labels*, and you can not have two labels named the same inside one function)
Notice that, even after this patch series, some places remain where "drm_modeset_lock_all()" and "drm_modeset_lock_all_ctx()" are still present, all inside drm core (which makes sense), except for two (in "amd" and "i915") which cannot be replaced due to the way they are being used.
Changes in v2: - Fix commit message typo - Use the value returned by DRM_MODESET_LOCK_ALL_END when possible - Split drm/i915 patch into two simpler ones - Remove drm_modeset_(un)lock_all() - Fix build problems in non-x86 platforms
Changes in v3: - Fix in drm/i915 driver to make sure global context is no longer used - Fix in drm/amdgpu driver to make sure global context is no longer used - Split amdgpu driver to make it easier to understand - Remove acquire_ctx from drm_mode_config - Rebase on top of drm-tip - WARNING: There is some discussion going on regarding whether the new macros should be used (or not) in the i915 driver, as a different set of functions has been proposed in the past (see here: https://lore.kernel.org/dri-devel/YVriZxCeipBUgc8O@intel.com/). In that case I will need to create a v4 where i915 files are left unchanged. Let me know your thoughts regarding this.
