starting one clock before the sync pulse rather than at the start
of the display area, which lets us drastically simplify the
overall timing calculations (verifying the changes by algebraic
operations is left as an exercise for the reader).

Finally, there were a couple of issues with the computation of
m->v.blankus that are addressed here.  Interlaced modes would
generate a negative intermediate result.  Double scan modes would

sun4i-drm changes for 4.13

An unusually big pull request for this merge window, with three notable
features:
  - V3s display engine support. This is especially notable because it uses
    a different display engine used on the newer Allwinner SoCs (H3, A64
    and the likes) that will be quite easily supported now.
  - HDMI support for the old Allwinner SoCs. This is enabled only on the
    A10s for now, but should be really easy to extend to deal with A10, A20
    and A31
  - Preliminary work to deal with dual-pipeline SoCs (A10, A20, A31, H3,
    etc.). It currently ignores the second pipeline, but we can use the
    dual-pipelines bindings. This will be useful to enable the display
    pipeline while we work on the dual-pipeline.

Fabio Estevam [Fri, 5 May 2017 18:01:41 +0000 (15:01 -0300)]
drm: mxsfb_crtc: Reset the eLCDIF controller

According to the eLCDIF initialization steps listed in the MX6SX
Reference Manual the eLCDIF block reset is mandatory.

Without performing the eLCDIF reset the display shows garbage content
when the kernel boots.

In earlier tests this issue has not been observed because the bootloader
was previously showing a splash screen and the bootloader display driver
does properly implement the eLCDIF reset.

Add the eLCDIF reset to the driver, so that it can operate correctly
independently of the bootloader.

Tested on a imx6sx-sdb board.

and then gives stress to memory on L1, I can observed this hang on L1 when
at least ~70% swap area is occupied on L0.

This is due to async pf was injected to L2 which should be injected to L1,
L2 guest starts receiving pagefault w/ bogus %cr2(apf token from the host
actually), and L1 guest starts accumulating tasks stuck in D state in
kvm_async_pf_task_wait() since missing PAGE_READY async_pfs.

This patch fixes the hang by doing async pf when executing L1 guest.
