drm/drivers: add support for using the arch wc mapping API.

2018-10-03T03:10:02+00:00

commit 7cf321d118a825c1541b43ca45294126fd474efa upstream.

This fixes a regression in all these drivers since the cache
mode tracking was fixed for mixed mappings. It uses the new
arch API to add the VRAM range to the PAT mapping tracking
tables.

Fixes: 87744ab3832 (mm: fix cache mode tracking in vm_insert_mixed())

drm/cirrus: bind also to qemu-xen-traditional

2014-11-05T11:43:10+00:00

commit c0c3e735fa7bae29c6623511127fd021b2d6d849 upstream.

qemu as used by xend/xm toolstack uses a different subvendor id.
Bind the drm driver also to this emulated card.

Merge tag 'topic/core-stuff-2014-05-05' of git://anongit.freedesktop.org/drm-intel into drm-next

Update pull request with drm core patches. Mostly some polish for the
primary plane stuff and a pile of patches all over from Thierry. Has
survived a few days in drm-intel-nightly without causing ill.

I've frobbed my scripts a bit to also tag my topic branches so that you
have something stable to pull - I've accidentally pushed a bunch more
patches onto this branch before you've taken the old pull request.

drm/cirrus: Remove unecessary NULL check in gem_free

2014-04-22T13:39:07+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.

drm/cirrus: Remove unnecessary NULL check in bo_unref

2014-04-22T13:39:06+00:00

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

drm: make mode_valid callback optional

2014-04-22T09:18:12+00:00

Many drm connectors do not need mode validation.
The patch makes this callback optional and removes dumb implementations.

v2: Rebase:
- imx move to a shared (but still dummy) ->mode_valid implementation.
- probe helpers have been extracted to drm_probe_helper.c

drm: cirrus: add power management support

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

cirrus 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.
Also make the mode_set function unblank the screen.

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]

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().
