      drm/exynos: release unhandled page flip events at postclose. · 0cbc330e
      由 Inki Dae 提交于 
      This patch resolves a dead lock issue that could be incurred when
exynos_drm_crtc_dpms function was called.

The exynos_drm_crtc_dpms function waits for the completion of pended
page flip events. However, preclose callback - this releases all unhandled
page flip events - is called prior to the exynos_drm_crtc_dpms function call
when drm is closed. So at this time, this will make the exynos_drm_crtc_dpms
to wait infiniately for the completion of the page flip events.

This patch releases the unhandled page flip events at postclose instead
of preclose so that exynos_drm_crtc_dpms function can be waked up.

Changelog v2:
- fix a memory leak when drm is closed.
  . it has a memory leak when a requeste page flip is handled after
    drm_events_release() is called and before drm_fb_release()
    is called. At this time, a drm_pending_event will not be freed.
    So also this chage releases the drm_pending_event at postclose().
    And it calls drm_vblank_put() for pair if there is any unhandled page
    flip event.

      drm: kill ->gem_init_object() and friends · 16eb5f43
      由 David Herrmann 提交于 
      All drivers embed gem-objects into their own buffer objects. There is no
reason to keep drm_gem_object_alloc(), gem->driver_private and
->gem_init_object() anymore.

New drivers are highly encouraged to do the same. There is no benefit in
allocating gem-objects separately.

      drm/exynos: add gsc ipp driver · f2646380
      由 Eunchul Kim 提交于 
      This patch adds IPP subsystem-based gsc driver for exynos5 series.
GSC is stand for General SCaler and supports the following features:
- image scaler/rotator/crop/flip/csc and input/output DMA operations.
- image rotation and image effect functions.
- writeback and display output operations.
- M2M operation to crop, scale, rotation and csc.

The below is GSC hardware path:
Memory------->GSC------>Memory
FIMD--------->GSC------>HDMI
FIMD--------->GSC------>Memory
Memory------->GSC------>FIMD, Mixer

This driver is registered to IPP subsystem framework to be used by user side
and user can control the GSC hardware through some interfaces of IPP subsystem
framework.

Changelog v1 ~ v5:
- added comments, code fixups and cleanups.

      drm/exynos: add rotator ipp driver · bea8a429
      由 Eunchul Kim 提交于 
      This patch adds IPP subsystem-based rotator driver.
And Rotator supports the following features.
- Image crop operation support.
- Rotate operation support to 90, 180 or 270 degree.
- Flip operation support to vertical, horizontal or both.
  . as limitaions, the pixel format to source buffer should be
    same as the one to destination buffer and no scaler.

This driver is registered to IPP subsystem framework to be used by user side
and user can control the Rotator hardware through some interfaces of IPP
subsystem framework.

Changelog v6:
- fix build warning.

Changelog v1 ~ v5:
- added comments, code fixups and cleanups.

      drm/exynos: add ipp subsystem · cb471f14
      由 Eunchul Kim 提交于 
      This patch adds Image Post Processing(IPP) support for exynos drm driver.

IPP supports image scaler/rotator and input/output DMA operations
using IPP subsystem framework to control FIMC, Rotator and GSC hardware
and supports some user interfaces for user side.

And each IPP-based drivers support Memory to Memory operations
with various converting. And in case of FIMC hardware, it also supports
Writeback and Display output operations through local path.

Features:
- Memory to Memory operation support.
- Various pixel formats support.
- Image scaling support.
- Color Space Conversion support.
- Image crop operation support.
- Rotate operation support to 90, 180 or 270 degree.
- Flip operation support to vertical, horizontal or both.
- Writeback operation support to display blended image of FIMD fifo on screen

A summary to IPP Subsystem operations:
First of all, user should get property capabilities from IPP subsystem
and set these properties to hardware registers for desired operations.
The properties could be pixel format, position, rotation degree and
flip operation.

And next, user should set source and destination buffer data using
DRM_EXYNOS_IPP_QUEUE_BUF ioctl command with gem handles to source and
destinition buffers.

And next, user can control user-desired hardware with desired operations
such as play, stop, pause and resume controls.

And finally, user can aware of dma operation completion and also get
destination buffer that it contains user-desried result through dequeue
command.

IOCTL commands:
- DRM_EXYNOS_IPP_GET_PROPERTY
  . get ipp driver capabilitis and id.
- DRM_EXYNOS_IPP_SET_PROPERTY
  . set format, position, rotation, flip to source and destination buffers
- DRM_EXYNOS_IPP_QUEUE_BUF
  . enqueue/dequeue buffer and make event list.
- DRM_EXYNOS_IPP_CMD_CTRL
  . play/stop/pause/resume control.

Event:
- DRM_EXYNOS_IPP_EVENT
  . a event to notify dma operation completion to user side.

Basic control flow:
Open -> Get properties -> User choose desired IPP sub driver(FIMC, Rotator
or GSCALER) -> Set Property -> Create gem handle -> Enqueue to source and
destination buffers -> Command control(Play) -> Event is notified to User
-> User gets destinition buffer complated -> (Enqueue to source and
destination buffers -> Event is notified to User) * N -> Queue/Dequeue to
source and destination buffers -> Command control(Stop) -> Free gem handle
-> Close
