Hi,
This patch set fixes some issues with the DisplayPort for the ZCU102:
The first patch fixes the wrong register size and thus the risk of register
overflow.
The three other one add a vblank interrupt required by the linux driver:
- When using the VNC graphic backend and leaving it unconnected, in the best
case the gfx_update callback is called once every 3000ms which is
insufficient for the driver. This is fixed by providing a VBLANK interrupt
from a ptimer.
- This requirement revealed two issues with the IRQ numbers and the
interrupt disable logic fixed by the two last patches.
Tested by:
- booting Petalinux with the framebuffer enabled.
- migrating the running guest and ensure that the vblank timer still fire
correctly.
Best Regards,
Fred
v2 -> v3:
* Added a VMSTATE in order to migrate the vblank timer as suggested
by Peter Maydell (Patch 2).
* Rebased on 0cac736e.
v1 -> v2:
* Better use of the ptimer API by using a correct POLICY as suggested
by Peter Maydell (Patch 2).
* Rebased on 78ac2eeb.
