drm/bochs: Constify function pointer structs

2015-12-15T12:42:36+00:00

Moves a bunch of junk to .rodata from .data.

drm/bochs: Store correct CRTC index in events

2015-12-15T12:35:48+00:00

Previously a negative pipe caused a special case to be triggered for
drivers that didn't have proper VBLANK support. The trigger for this
special case is now independent of the pipe, so the correct CRTC index
can now be stored in events.

v2: convert to use drm_crtc_send_vblank_event()

drm: Pass 'name' to drm_encoder_init()

2015-12-11T08:13:20+00:00

Done with coccinelle for the most part. However, it thinks '...' is
part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder
in its place and got rid of it with sed afterwards.

drm: Pass the user drm_mode_fb_cmd2 as const to .fb_create()

2015-11-24T10:47:38+00:00

Drivers shouldn't clobber the passed in addfb ioctl parameters.
i915 was doing just that. To prevent it from happening again,
pass the struct around as const, starting all the way from
internal_framebuffer_create().

drm/bochs: Don't grab dev->struct_mutex for in mmap offset ioctl

2015-08-10T11:37:04+00:00

Since David Herrmann's mmap vma manager rework we don't need to grab
dev->struct_mutex any more to prevent races when looking up the mmap
offset. Drop it and instead don't forget to use the unref_unlocked
variant (since the drm core still cares).

drm/bochs: Use new drm_fb_helper functions

2015-08-06T12:13:06+00:00

Use the newly created wrapper drm_fb_helper functions instead of calling
core fbdev functions directly. They also simplify the fb_info creation.

v3:
- Don't touch remove_conflicting_framebuffers

v2:
- remove unused variable device in bochsfb_create

drm/bochs: disable video before changing video mode

2015-03-31T22:28:15+00:00

qemu and simics simulators both seem to expect that video should be disabled
before changing the video mode.

drm/fb-helper: Propagate errors from initial config failure

2015-01-21T13:57:03+00:00

Make drm_fb_helper_initial_config() return an int rather than a bool so
that the error can be properly propagated. While at it, update drivers
to propagate errors further rather than just ignore them.

v2:
- cirrus: No cleanup is required, the top-level cirrus_driver_load()
  will do it as part of cirrus_driver_unload() in its cleanup path.

drm/bochs: Remove dummy ->load_lut() implementation

The ->load_lut() callback is optional, therefore a dummy implementation
is not needed.

bochs: add page_flip

2014-11-20T01:27:31+00:00

Implement crtc page_flip callback for bochsdrm.  The qemu stdvga has no
vblank signaling, so we have to fake it.  We do so by instantly calling
drm_send_vblank_event.  Tested with kmscon.
