<div class="gmail_quote">2012/11/2 Imre Deak <<a href="mailto:imre.deak@intel.com" target="_blank">imre.deak@intel.com</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> The patchset adds the missing event_lock when accessing the vblank_event_list in drm_vblank_off() and as preparation for this also fixes a few other issues in the exynos driver. This is also a dependency for Rob Clark's drm_send_vblank_event() rework as that would trigger a warning for the unhold event_lock without this changeset. The exynos changes are only compile tested, the rest is tested on an Intel IVB machine on top of drm-intel-nightly + drm_send_vblank_event() rework, with i-g-t/flip_test. </blockquote><div> Hi Imre, Works fine. But we should wait for Rob's patch set to be merged to -next, and this may be rebased on top of latest Rob's patch set again. Thanks, Inki Dae </div> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> In v2: - Instead of fixing the event_lock vs. vblank_time_lock lockdep issue in drm_handle_vblank(), fix it in the exynos driver. This looks like the more logical thing to do and this way we also have a smaller impact on the rest of DRM code.
