Subject: [Intel-gfx] [PATCH 0/4] drm: Make modeset locking easier
Date: Thu, 15 Jul 2021 21:49:50 +0300	[thread overview]
Message-ID: <20210715184954.7794-1-ville.syrjala@linux.intel.com> (raw)

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

While staring at some DRM_MODESET_LOCK_ALL_{BEGIN,END}() conversions
I decided I don't really like what those macros do.

The main problems that I see:
- the magic goto inside limits their usefulness to baically
  a single statement, unless you're willing to look inside and
  find out the name of the magic label
- can't help at all in the "we don't want to lock everything"
  cases, which are quite numerous
- not at all obvious that there's a loop in there

So I figured I'd try to come up with something more universally useful.

Ville Syrjälä (4):
  drm: Introduce drm_modeset_lock_ctx_retry()
  drm: Introduce drm_modeset_lock_all_ctx_retry()
  drm/i915: Extract intel_crtc_initial_commit()
  drm/i915: Use drm_modeset_lock_ctx_retry() & co.
