10 years agoOMAPDSS: DSSCOMP: New composition module
Lajos Molnar [Wed, 27 Mar 2013 17:44:05 +0000 (12:44 -0500)]
OMAPDSS: DSSCOMP: New composition module

This patch implements a new DSS composition module.

DSSCOMP allows specifying a whole composition for a DSS display:

    1. set overlay information for all overlays on a manager
    2. reroute the overlays to the manager (overlay must be disabled
       just as when using sysfs)
    3. set manager information
    4. optionally call manager->apply() that programs the DISPC
    4. optionally do an update (after a sync call)

    DSS already implements coordinated updates by separating overlay
    information setting from the applicaion of those settings (which
    happens only in manager->apply()).  However current clients of DSS
    call manager->apply() for each change, which make coordinated
    change impossible.

    This API also implements auto cropping of all layers to the display
    region.  This makes switching displays and handling display resolution
    changes easier (without getting "failed to setup overlay" messages.)

DSSCOMP operates on 3 levels.

base.c contains the basic DSS operations, such as setting DSS overlay
and managers using DSSCOMP's setting structures.  Theoretically,
DSSCOMP could be used via only these operations.

queue.c contains the queuing mechanism.  This module maintains
compositions queued to each overlay manager (the basic DSS composition
entity).  Queueing operations consist of creating a composition,
setting/getting manager/overlay information for the composition,
applying the composition to the display (which also displays it
on manually updated panels), waiting on various states of a composition.

For now the basic queuing mechanism of DSSCOMP is "queue and forget".
Therefore, it is not necessary to dequeue each frame queued.  A
consequence of this methodology is that if one applies a composition
to a display, any prior unapplied compositions will be dropped.

Compositions are applied asynchronously (delayed apply) so that
they can be queued from irq context.

The queuing interface tracks which overlay is assigned to which
manager.  This is done at the DSS programming level, as that is the
most reliable place to monitor overlay ownership.  Nonetheless,
the device interface uses overlay information to verify overlay
ownership - which may be slightly out of sync.  The user of
DSSCOMP should maintain overlay ownership to ensure flawless
sharing of overlays between managers.  (E.g. should not use an
overlay on a new manager, until the overlay has been disabled on
the previous manager, and that composition has been programmed.)

Buffers must be displayable (e.g. TILER2D or physically contiguous).

device.c contains the device hooks to operating system, and the file
interface (via /dev/dsscomp's ioctls).  /dev/dsscomp works on top of
the queueing mechanism.

There are 3 levels of header files.

linux/dsscomp.h: basic dsscomp structures and ioctls
plat/dsscomp.h: kernel dsscomp interface (on top of linux/dsscomp.h)
local dsscomp.h: common implementation structures and shared methods

An additional Android adaptation layer is also provided.  This
sits on top of DSSCOMP and allows specifying all overlays on all
managers in a single operation as required by Android's rendering
model.  Here the checking of overlays is slightly relaxed as
Android makes sure that an overlay is detached from a display
before it is attached to another one.  This interface also
uses ION/TILER to remap non-contiguous buffers into contiguous
TILER1D space - so they can be displayed by DISPC.

At the Android level buffers can be specified with a set of
pages, using offsets into FBMEM (contiguous), or by referencing
prior overlays (e.g. cloning).

Note: plat/dsscomp.h defines a handle typedef that causes a
checkpatch warning.  I feel that the creation of a handle typedef
is warranted.

Limitations:
- no WB support
- unsure whether to call sync on non-manual update panels
- cannot get overlay/manager information on a composition without
first having set it

one display device to omapfb_fb_init() to work with, which causes
all framebuffers to be of same resolution. Instead we assign each

OMAPDSS: OMAPFB: Do not suspend HDMI driver in early suspend.

Issue:
HDMI Audio can be active even if display activity
times out.

Analysis:
To save power approach to suspend panel on an
early suspend call was taken. This call of panel
suspend is done by OMAPLFB on early suspend
callback.

There is no issue in case of LCD since it doesnt
carry any audio. Also we only suspend the default
panel and not all the connected panels.

If hdmi is default display we cut HDMI clocks via
omapfb->blank call with NORMAL enum. HDMI audio
driver will close DMA only after the timeout
in userspace.

So we are voilating the expectation of HDMI audio
driver in case HDMI is default panel.

In case HDMI is default there is almost no use case
with battery power devices.

With this fix we can have an HDMI audio playback
happening when display inactivity times out
triggering early suspend.

gpu: ion: omap: add apis to register and export ion buffers from a pvr fd

Exporting omap_ion_register_pvr_export through ion. This is needed since
PVR is built as a module as the abstraction uses an exported function
pointer.

omap_ion_share_fd_to_buffers api is added which retrieves the ion handles
from the pvr fd and calls ion_share on the ion handles to return the
shared buffers. The requestor can then call ion_import using its own ion
client to get its own ion handles.

Note that this functionality is intended to be reworked majorly as part of
gralloc's migration to dma buf functionality in new ION framework.

The reason for the code movement of ion structs is due to

ASoC: davinci-mcasp: clean up davinci_hw_common_param()

As pointed of by Vaibhav, commit 2952b27e2 ("ASoC: davinci-mcasp:
Add support for multichannel playback") duplicated the logic of
counting the active serializers. That can be avoided by shifting
the code around a bit.

Also, drop two unused defines introduced by the same commit.

ASoC: davinci-mcasp: Add support for multichannel playback

Davinci McASP has support for I2S multichannel playback.
For I2S playback/receive, each serializer is capable to play 2 channels
(L/R) audio data.Serializer function (Playback-receive-none) is configured
in DT, depending on hardware specification. It is possible to play less
channels than configured in DT. For that purpose,only specific number of
active serializers are enabled. McASP FIFO need to have DMA transfer Bcnt
set to number of enabled serializers, otherwise no data are transfered to
McASP and Alsa generates "DMA/IRQ playback write error (DMA or IRQ trouble?)"
error. For TDM mode, McASP is capable to play or receive 32 channels for one
serializer. McAsp has support for max 16 serializer, therefore max channels
is 32 * 8.

ASoC: McASP: Fix data rotation for playback. Enables 24bit audio playback

u32 rotate = (32 - word_length) / 4;
This implementation is wrong, but it works only for 16, or 32 bit audio data.
(rotation for 16 or 32 bit is same as in code I present) Mcasp rotated data in
4 bits (max value 0x7)and then masks them . That data are sended to i2s bus.
For 24 bit or 20 bit or other data formats, this code rotates data badly and
you hear somethink like noise.  You need to use
u32 rotate = (word_length / 4) & 0x7;
to proper data rotation.
