drm/bochs: Remove unecessary NULL check in gem_free

2014-04-22T13:39:40+00:00

The ->gem_free_object never gets called with a NULL pointer, the check
is redundant. Also checking after the upcast allows compilers to elide
it anyway.

Noticed while chasing coverity reports, somehow this one here was not
flagged.

drm/bochs: Remove unnecessary NULL check in bo_unref

2014-04-22T13:39:39+00:00

ttm_bo_unref unconditionally calls kref_put on it's argument, so the
thing can't be NULL without already causing Oopses.

Spotted by coverity.

drm: bochs: add power management support

2014-04-18T03:31:49+00:00

bochs kms driver lacks power management support, thus
the vga display doesn't work any more after S3 resume.

Fix this by adding suspend and resume functions.

drm: Replace crtc fb with primary plane fb (v3)

2014-04-02T00:18:28+00:00

Now that CRTC's have a primary plane, there's no need to track the
framebuffer in the CRTC.  Replace all references to the CRTC fb with the
primary plane's fb.

This patch was generated by the Coccinelle semantic patching tool using
the following rules:

        @@ struct drm_crtc C; @@
        -   (C).fb
        +   C.primary->fb

        @@ struct drm_crtc *C; @@
        -   (C)->fb
        +   C->primary->fb

v3: Generate patch via coccinelle.  Actual removal of crtc->fb has been
    moved to a subsequent patch.

v2: Fixup several lingering crtc->fb instances that were missed in the
    first patch iteration.  [Rob Clark]

Merge branch 'drm-next' of git://people.freedesktop.org/~dvdhrm/linux into drm-next

2014-03-18T09:17:02+00:00

This is the 3rd respin of the drm-anon patches. They allow module unloading, use
the pin_fs_* helpers recommended by Al and are rebased on top of drm-next. Note
that there are minor conflicts with the "drm-minor" branch.

* 'drm-next' of git://people.freedesktop.org/~dvdhrm/linux:
  drm: init TTM dev_mapping in ttm_bo_device_init()
  drm: use anon-inode instead of relying on cdevs
  drm: add pseudo filesystem for shared inodes

drm: init TTM dev_mapping in ttm_bo_device_init()

2014-03-16T11:23:42+00:00

With dev->anon_inode we have a global address_space ready for operation
right from the beginning. Therefore, there is no need to do a delayed
setup with TTM. Instead, set dev_mapping during initialization in
ttm_bo_device_init() and remove any "if (dev_mapping)" conditions.

drm: use anon-inode instead of relying on cdevs

2014-03-16T11:23:33+00:00

DRM drivers share a common address_space across all character-devices of a
single DRM device. This allows simple buffer eviction and mapping-control.
However, DRM core currently waits for the first ->open() on any char-dev
to mark the underlying inode as backing inode of the device. This delayed
initialization causes ugly conditions all over the place:
  if (dev->dev_mapping)
    do_sth();

To avoid delayed initialization and to stop reusing the inode of the
char-dev, we allocate an anonymous inode for each DRM device and reset
filp->f_mapping to it on ->open().

drm/bochs: new driver

2013-12-23T01:02:39+00:00

DRM driver for (virtual) vga cards using the bochs dispi
interface, such as the qemu standard vga (qemu -vga std).

Don't bother supporting anything but 32bpp for now, even
though the virtual hardware is able to do that.

Known issue: mmap(/dev/fb0) doesn't work.
