drm: Only use compat ioctl for addfb2 on X86/IA64

2016-10-03T12:35:10+00:00

[ Upstream commit 47a66e45d7a7613322549c2475ea9d809baaf514 ]

Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an
unaligned 64 bit field (modifier). This get packed differently between
32 bit and 64 bit modes on architectures that can handle unaligned 64
bit access (X86 and IA64).  Other architectures pack the structs the
same and don't need the compat wrapper. Use the same condition for
drm_mode_fb_cmd2 as we use for drm_update_draw.

Note that only the modifier will be packed differently between compat
and non-compat versions.

drm: atmel-hlcdc: Fix vertical scaling

2016-10-02T23:12:14+00:00

[ Upstream commit d31ed3f05763644840c654a384eaefa94c097ba2 ]

The code is applying the same scaling for the X and Y components,
thus making the scaling feature only functional when both components
have the same scaling factor.

Do the s/_w/_h/ replacement where appropriate to fix vertical scaling.

drm: Reject page_flip for !DRIVER_MODESET

2016-08-31T23:21:09+00:00

[ Upstream commit 6f00975c619064a18c23fd3aced325ae165a73b9 ]

Somehow this one slipped through, which means drivers without modeset
support can be oopsed (since those also don't call
drm_mode_config_init, which means the crtc lookup will chase an
uninitalized idr).

This should fix some unaligned access warnings. This is also likely to
fix non-descript issues on nv30/nv34 as a result of incorrect channel
setup.

drm/nouveau/fbcon: fix font width not divisible by 8

2016-08-20T03:07:58+00:00

[ Upstream commit 28668f43b8e421634e1623f72a879812288dd06b ]

The patch f045f459d925 ("drm/nouveau/fbcon: fix out-of-bounds memory accesses")
tries to fix some out of memory accesses. Unfortunatelly, the patch breaks the
display when using fonts with width that is not divisiable by 8.

The monochrome bitmap for each character is stored in memory by lines from top
to bottom. Each line is padded to a full byte.

For example, for 22x11 font, each line is padded to 16 bits, so each
character is consuming 44 bytes total, that is 11 32-bit words. The patch
f045f459d925 changed the logic to "dsize = ALIGN(image->width *
image->height, 32) >> 5", that is just 8 words - this is incorrect and it
causes display corruption.

This patch adds the necesary padding of lines to 8 bytes.

This patch should be backported to stable kernels where f045f459d925 was
backported.
