[RESEND][PATCH v3 00/26] drm: Kirin driver cleanups to prep for Kirin960 support

[John Stultz]

Just wanted to resend this patch set so I didn't have to
continue carrying it forever to keep the HiKey960 board running.

This patchset contains one fix (in the front, so its easier to
eventually backport), and a series of changes from YiPing to
refactor the kirin drm driver so that it can be used on both
kirin620 based devices (like the original HiKey board) as well
as kirin960 based devices (like the HiKey960 board).

The full kirin960 drm support is still being refactored, but as
this base kirin rework was getting to be substantial, I wanted
to send out the first chunk, so that the review burden wasn't
overwhelming.

The full HiKey960 patch stack can be found here:

[RESEND][PATCH v3 01/26] drm: kirin: Fix for hikey620 display offset problem

[John Stultz]

From: Da Lv <lvda3@hisilicon.com>

The original HiKey (620) board has had a long running issue
where when using a 1080p montior, the display would occasionally
blink and come come back with a horizontal offset (usually also
shifting the colors, depending on the value of the offset%4).

After lots of analysis by HiSi developers, they found the issue
was due to when running at 1080p, it was possible to hit the
device memory bandwidth limits, which could cause the DSI signal
to get out of sync.

Unfortunately the DSI logic doesn't have the ability to
automatically recover from this situation, but we can get a an
LDI underflow interrupt when it happens.

To then correct the issue, when we get an LDI underflow irq, we
we can simply suspend and resume the display, which resets the
hardware.

Thus, this patch enables the ldi underflow interrupt, and
initializes a workqueue that is used to suspend/resume the
display to recover. Then when the irq occurs we clear it and
schedule the workqueue to reset display engine.

From: Xu YiPing <xuyiping@hisilicon.com>

In a few functions, we pass in a struct ade_crtc, which we only
use to get to the underlying struct ade_hw_ctx.

Thus this patch refactors the functions to just take the
struct ade_hw_ctx directly.

[RESEND][PATCH v3 08/26] drm: kirin: Rename ade_crtc to kirin_crtc

[John Stultz]

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch renames the
struct ade_crtc to kirin_crtc.

The struct kirin_crtc will later used by both kirin620 and
future kirin960 driver, and will be moved to a common
kirin_drm_drv.h in a future patch

[RESEND][PATCH v3 09/26] drm: kirin: Dynamically allocate the hw_ctx

[John Stultz]

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch modifies the
initialization function to dynamically allocate the ade_hw_ctx
structure previously kept as part of struct ade_data.

This is done so that later we can have the hw_ctx point to
hardware revision specific ctx structures.

[RESEND][PATCH v3 10/26] drm: kirin: Move request irq handle in ade hw ctx alloc

[John Stultz]

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch modifies the
initialization routines so the devm_request_irq() function
is called as part of the allocation function.

This will be needed in the future when we will have different
allocation functions to allocate hardware specific hw_ctx
structures, which will setup the vblank irq differently.

[RESEND][PATCH v3 11/26] drm: kirin: Move workqueue to ade_hw_ctx structure

[John Stultz]

The workqueue used to reset the display when we hit an LDI
underflow error is ADE specific, so since this patch series
works to make the kirin_crtc structure more generic, move the
workqueue to the ade_hw_ctx structure instead.

[RESEND][PATCH v3 12/26] drm: kirin: Move kirin_crtc, kirin_plane, kirin_format to kirin_drm_drv.h

[John Stultz]

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves some shared
structures and helpers to the common kirin_drm_drv.h

These structures will later used by both kirin620 and
future kirin960 driver

[RESEND][PATCH v3 16/26] drm: kirin: Move mode config function to driver_data

[John Stultz]

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves the mode config
initialization values into the kirin_drm_data structure.

This will make it easier to add support for new devices
via a new kirin_drm_data structure.

[RESEND][PATCH v3 21/26] drm: kirin: Rename plane_init and crtc_init

[John Stultz]

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch renames
ade_crtc/plane_init kirin_plane/crtc_init, as they will later be
moved to kirin drm drv and shared with the kirin960 hardware
support.

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support

dev->driver_data to point to a drm_device, not ade_data.

Thus we set the driver data to drm device after alloc.

[RESEND][PATCH v3 25/26] drm: kirin: Pass driver data to crtc init and plane init

[John Stultz]

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch changes the code
via a passed in driver_data pointer, rather than hardcoding
them via ade_driver_data variable.

This will allow those funcitons to be later moved to the
generic kirin_drm_drv.c using alternative driver_data structures
that support other hardware.

[John Stultz]

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch renames ade_data to
kirin_drm_private, and moves crtc_init and plane_init to
kirin drm drv too. Now that they are generic the functions
can be shared between the kirin620 and (to be added later)
kirin960 specific support code.

As Maintainers can we please get some feedback from one of you.
Just an "OK to commit" would do it.
But preferably an ack or a review on the individual patches.

If the reality is that John is the Maintainer today,
then we should update MAINTAINERS to reflect this.

Thanks!

Hi sam,
So sorry for responding late.
As I have done a pre-review and talked with the  author before sending 
out the patches.
So, for this serial patches,
Acked-by: Xinliang Liu <z.liuxinliang@hisilicon.com>

I am assuming you are talking about the kirin[1] drm driver not the 
hibmc[2] one, right?
I really appreciate John's awesome work at kirin drm driver all the way.
Honestly, after my work change from mobile to server years ago, I am 
always waiting for some guy who is stably working at kirin drm driver to 
take the maintenance work.
John, surely is a such guy.  Please add up a patch to update the 
maintainer as John, if John agree so.  Then John can push the patch set 
to drm maintainer himself.
*Note* that the maintainer patch should break hisilicon drivers into 
kirin and hibmc two parts, like bellow:

DRM DRIVERS FOR HISILICON HIBMC
M:  Xinliang Liu <z.liuxinliang@hisilicon.com>
...
F:  drivers/gpu/drm/hisilicon/hibmc
...

DRM DRIVERS FOR HISILICON KIRIN
M:  John Stultz <john.stultz@linaro.org>
...
F:  drivers/gpu/drm/hisilicon/kirin
...

[1] drivers/gpu/drm/hisilicon/kirin # for kirin mobile display driver
[2] drivers/gpu/drm/hisilicon/hibmc # for server VGA driver


Thanks,
Xinliang

Thanks!
We all know how it is to be busy, especially when trying to keep up
after role changes.
Unless someone beats me, then I will apply tonight or tomorrow.

Hi John

Up to the challenge?
If yes then please consider to apply for commit rights to drm-misc-next.

And read:
https://drm.pages.freedesktop.org/maintainer-tools/index.html

See this to get an account:
https://www.freedesktop.org/wiki/AccountRequests/

You will need an ssh account for drm-misc-next as it is not (yet?)
gitlab enabled.

	Sam

I guess if necessary, though I don't believe myself to be a great maintainer.

Though I do have the hardware, am regularly are testing on it, and
maintain a tree of patches to keep it working, so I can validate basic
correctness and handle patch wrangling.

I'll try to find some time to read through the above and apply.
