From b7ea04d299c78b6cf96ab281a1683ff62a74f969 Mon Sep 17 00:00:00 2001 From: Sean Paul Date: Thu, 29 Nov 2018 10:04:17 -0500 Subject: drm: Add DRM_MODESET_LOCK_BEGIN/END helpers This patch adds a couple of helpers to remove the boilerplate involved in grabbing all of the modeset locks. I've also converted the obvious cases in drm core to use the helpers. The only remaining instance of drm_modeset_lock_all_ctx() is in drm_framebuffer. It's complicated by the state clear that occurs on deadlock. ATM, there's no way to inject code in the deadlock path with the helpers, so it's unfit for conversion. Changes in v2: - Relocate ret argument to the end of the list (Daniel) - Incorporate Daniel's doc suggestions (Daniel) Suggested-by: Daniel Vetter Reviewed-by: Daniel Vetter Signed-off-by: Sean Paul Link: https://patchwork.freedesktop.org/patch/msgid/20181129150423.239081-4-sean@poorly.run --- include/drm/drm_modeset_lock.h | 59 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 59 insertions(+) (limited to 'include/drm') diff --git a/include/drm/drm_modeset_lock.h b/include/drm/drm_modeset_lock.h index a685d1bb21f2..a308f2d6496f 100644 --- a/include/drm/drm_modeset_lock.h +++ b/include/drm/drm_modeset_lock.h @@ -130,4 +130,63 @@ void drm_warn_on_modeset_not_all_locked(struct drm_device *dev); int drm_modeset_lock_all_ctx(struct drm_device *dev, struct drm_modeset_acquire_ctx *ctx); +/** + * DRM_MODESET_LOCK_ALL_BEGIN - Helper to acquire modeset locks + * @dev: drm device + * @ctx: local modeset acquire context, will be dereferenced + * @flags: DRM_MODESET_ACQUIRE_* flags to pass to drm_modeset_acquire_init() + * @ret: local ret/err/etc variable to track error status + * + * Use these macros to simplify grabbing all modeset locks using a local + * context.
