Hi All,
This patch-set is the result of the work I've been doing recently to
give people a smooth "flickerfree" boot experience where the display
keeps displaying the logo put there by the firmware until it smoothly
fades into the Linux GUI (e.g. gdm).
While testing this on some BYT/CHT devices I noticed the screen going
black for 1 second or so, because the first modeset was not a fast
modeset despite passing i915.fastboot=1 on the kernel commandline.
This is caused by the GOP and the i915 code differing in what they
think the DSI pclk should be. This patch-set fixes this by reading
back the pclk set by the GOP and if it is reasonably close to the
clk calculated by the i915 code, using the GOP set pclk.
Ping? A review of this series would be appreciated.
Sorry, swamped, and I was hoping Ville would chime in. ;)
The first two patches are trivial, ack. But I'd really like to know what
the GOP is doing, and why we're different. Not sure if that's possible.
I'm afraid after much bikeshedding there were some file and function
renames, and no matter what this series needs a rebase. See [1]. Sorry
about the extra effort this causes; I truly appreciate your efforts with
the DSI code, and I regret I haven't given this series the love it
needs.
No problem. I'll pick up those patches and do a rebase, I'm currently
travelling so I don't have access to hardware to test this for a couple of
days. I will post a rebased version when I'm back.
Regards,
Hans
