Subject: [Qemu-devel] [PATCH v3 0/2] Add vfio dma-buf based display reset handling
Date: Thu, 26 Apr 2018 16:21:18 +0800	[thread overview]
Message-ID: <1524730880-7154-1-git-send-email-tina.zhang@intel.com> (raw)

vfio display needs to release the invalid display resource and disable
the scanout mode during guest OS reboot, otherwise bugs come out.

Thanks hang.yuan@intel.com for helping root cause the issue.

v2->v3:
 - Limit vfio_display_reset to dma-buf based vfio display. (Gerd)

v1->v2:
 - remove dpy_gfx_switch_surface. (Gerd)
 - add dpy_gfx_update_full. (Gerd)

Tina Zhang (2):
  console: introduce dpy_gfx_update_full
  ui: introduce vfio_display_reset
