      drm/i915/gt: Save irqstate around virtual_context_destroy · 36deeddc
      Chris Wilson authored
      As virtual_context_destroy() may be called from a request signal, it may
      be called from inside an irq-off section, and so we need to do a full
      save/restore of the irq state rather than blindly re-enable irqs upon
      unlocking.

      drm: meson: venc: cvbs: fix CVBS mode matching · 43cb8679
      Martin Blumenstingl authored
      With commit 222ec161 ("drm: Add aspect ratio parsing in DRM
      layer") the drm core started honoring the picture_aspect_ratio field
      when comparing two drm_display_modes. Prior to that it was ignored.
      When the CVBS encoder driver was initially submitted there was no aspect
      ratio check.
      
      Switch from drm_mode_equal() to drm_mode_match() without
      DRM_MODE_MATCH_ASPECT_RATIO to fix "kmscube" and X.org output using the
      CVBS connector. When (for example) kmscube sets the output mode when
      using the CVBS connector it passes HDMI_PICTURE_ASPECT_NONE, making the
      drm_mode_equal() fail as it include the aspect ratio.
      
      Prior to this patch kmscube reported:
        failed to set mode: Invalid argument
      
      The CVBS mode checking in the sun4i (drivers/gpu/drm/sun4i/sun4i_tv.c
      sun4i_tv_mode_to_drm_mode) and ZTE (drivers/gpu/drm/zte/zx_tvenc.c
      tvenc_mode_{pal,ntsc}) drivers don't set the "picture_aspect_ratio" at
      all. The Meson VPU driver does not rely on the aspect ratio for the CVBS
      output so we can safely decouple it from the hdmi_picture_aspect
      setting.
