[PATCH 00/16] drm/omap: misc cleanups and pixel format change

[Tomi Valkeinen]

Hi,

This series has a bunch of cleanups. We drop DMA and VRFB rotation, and RFBI
output. None of those are supported.

The latter half is about getting rid of enum omap_color_mode and moving to use
fourcc pixel formats.

There should be no functional changes caused by this series.

This series is based on my earlier "drm/omap: misc changes" series.

 Tomi

[PATCH 01/16] drm/omap: fix passing rotation parameter to dispc

[Tomi Valkeinen]

omapdrm does not pass the rotation angle to dispc. We need to pass the
rotation angle to fully support TILER rotation with YUV formats.

[PATCH 02/16] drm/omap: fix setting & clearing DOUBLESTRIDE

[Tomi Valkeinen]

The code that sets and clears DOUBLESTRIDE is only ran when using NV12.
This is not correct, as we might first set the bith when using NV12, but
never clear it when using other formats.

Fix it so that when the bit is available (when the HW supports NV12) we
always either set or clear the bit.

[PATCH 03/16] drm/omap: remove CLUT

[Tomi Valkeinen]

DSS IP versions 2 and 3 support CLUT modes (color lookup table), but the
driver has never supported those. We still have had some code for CLUT
modes. As the newer DSS IP versions have dropped CLUT support, we might
as well clean up the driver by removing the CLUT related code.

[PATCH 05/16] drm/omap: remove rfbi

[Tomi Valkeinen]

The RFBI driver has not worked nor compiled for many years. There are
very few boards out there that use RFBI, and no one has stepped up to
fix it.

So let's remove the RFBI code that doesn't even compile.

[PATCH 06/16] drm/omap: remove dma & vrfb rotation

[Tomi Valkeinen]

We have three rotation methods supported by the SoCs with DSS: DMA,
VRFB and TILER.

DMA rotation works in theory on all DSS platforms, but in practice it's
unusable due to the huge amount of memory bandwidth it uses, and has
never really been used.

VRFB is available on OMAP3, but is not supported by omapdrm, even though
we have some code for it in the dispc driver.

TILER is supported on OMAP4/OMAP5/DRA7/AM5 platforms, but has some
driver bugs.

To clean up the driver to help fixing the TILER issues, this patch drops
the DMA and VRFB rotation support, leaving only TILER rotation.

[PATCH 08/16] drm/omap: add format_is_yuv() helper

[Tomi Valkeinen]

In a few places the dispc driver needs to know whether the pixel format
is an YUV format. Add a helper to figure that out.

[PATCH 11/16] drm/omap: change supported_modes to an array

[Tomi Valkeinen]

enum omap_color_mode is a bitmask, so at the moment we present the
supported color modes as mask. To be able to move to fourccs, we need to
use an array to present the supported color modes.

As a first step towards fourccs, this patch changes the code to use an
array to store the enums.

[PATCH 12/16] drm/omap: use DRM_FORMAT_* instead of OMAP_DSS_COLOR_*

[Tomi Valkeinen]

This patch changes omapdrm to use DRM_FORMAT_* values instead of
OMAP_DSS_COLOR_* enum. This patch only changes the uses of
OMAP_DSS_COLOR_*, so we still keep the enum omap_color_mode. I.e. we now
temporarily pass DRM_FORMAT_* values with enum omap_color_mode.

This causes a few compile warnings with switch()es, so those need a
typecast to (u32) to silence the warnings.

[PATCH 13/16] drm/omap: use u32 instead of enum omap_color_mode

[Tomi Valkeinen]

In this step we drop 'enum omap_color_mode', and use u32 instead.

[PATCH 14/16] drm/omap: remove omap_framebuffer_get_formats()

[Tomi Valkeinen]

We now get a fourcc array from dispc when asking for a plane's supported
pixel formats, so we can drop omap_framebuffer_get_formats() which was
used to convert between DSS and DRM pixel formats.

[PATCH 15/16] drm/omap: cleanup formats array

[Tomi Valkeinen]

omap_fb.c has a table with DSS and DRM formats, used to convert between
them. This is no longer needed, so we can change the array to a plain
array of DRM_FORMAT_* values which contain all possible pixel formats
supported by any DSS IP version.

[PATCH 16/16] drm/omap: rename color_mode to fourcc

[Tomi Valkeinen]

Now that we use fourccs, we can also rename the 'color_mode' variables
to 'fourcc'.

Patches 1 and 5 are not valid anymore. 5 has been already merged via
another series, and I've since reworked 1, which I'll be handling in a
separate tiler rotation series. The rest are still valid.

I'm fine dropping DMA rotation, but I have mixed feelings about VRFB. Yes, it 
doesn't work at the moment, but I know users of VRFB with the omap_vout driver 
who would really like to switch to omapdrm. Porting VRFB from omap_vout to 
omapdrm has been on my to-do list for a long time (with a low priority 
unfortunately). As an added bonus, it would allow dropping the omap_vout 
driver at some point.

What would you think about dropping DMA but keeping VRFB for now ?

This is a condition that should be checked by omapdrm in the atomic_check 
phase, to avoid returning an error in the atomic_commit phase.

Same here.

We can fix that as a follow-up patch, so

This seems to conflict with "drm/omap: remove omap_overlay & 
omap_overlay_manager" :-)

This patch doesn't remove that much about vrfb, just the row/pix inc
calculations. The main vrfb file is still there, for omapfb. I'm happy
to add it back when someone has a working prototype for omapdrm+vrfb,
but to be honest, I won't hold my breath =).

I really want to clean up the dispc driver as much as possible, as it's
such a messy piece of code, supporting so many DSS IP versions. I
believe we'll get a cleaner version if we add the vrfb back from scratch.

I believe this should go before 12/16, otherwise you end up temporarily 
storing DRM_FORMAT_* values in enum omap_color_mode variables.

Apart from that,

Wouldn't it make sense to modify the way supported formats are stored 
internally to store both the array and its size ? We could then return both 
from ovl_get_color_modes(), which would save us from computing the size at 
runtime. This can be done in a subsequent patch, so

As commented in patch 13/16, the warning is there for a reason, I think you 
should move patch 13/16 before this one.

I'll trust your search & replace skills and won't verify the formats. For the

That's on purpose, I mention it in the previous patch. Do you see a
problem with it?

If I change the order, then I'd be going back and forth with u32 and
enum omap_color_mode.

But I could squash this and 12 together. That's perhaps the technically
most correct option, but I wanted to split the changes into a bit
smaller pieces.

I don't like this macro much, but I don't think I have a much better proposal 
beside just typing the cast out :-/, so

It's dirty :-) You had to silence a few warnings with explicit casts because 
of that.

If you first switch to u32, there's nothing wrong storing the enum 
omap_color_mode value in a u32, and it will then be easy to transition to 
DRM_FORMAT_*.

True, I did that and the end result looks a bit cleaner. Thanks!
