fbdev: fbmem: convert CONFIG_FB_LOGO_CENTER into a cmd line option

2019-01-16T16:42:35+00:00

A command line option is much more flexible than a config option and
the supporting code is small. Gets rid of #ifdefs in the code too...

fbdev: make FB_BACKLIGHT a tristate

2018-12-20T18:13:07+00:00

BACKLIGHT_CLASS_DEVICE is already tristate, but a dependency
FB_BACKLIGHT prevents it from being built as a module.  There
doesn't seem to be any particularly good reason for this, so
switch FB_BACKLIGHT over to tristate.

fbdev: Add FBINFO_HIDE_SMEM_START flag

2018-09-11T12:11:54+00:00

DRM drivers really, really, really don't want random userspace to
share buffer behind it's back, bypassing the dma-buf buffer sharing
machanism. For that reason we've ruthlessly rejected any IOCTL
exposing the physical address of any graphics buffer.

Unfortunately fbdev comes with that built-in. We could just set
smem_start to 0, but that means we'd have to hand-roll our own fb_mmap
implementation. For good reasons many drivers do that, but
smem_start/length is still super convenient.

Hence instead just stop the leak in the ioctl, to keep fb mmap working
as-is. A second patch will set this flag for all drm drivers.

fbdev: Drop FBINFO_CAN_FORCE_OUTPUT flag

2018-09-11T12:11:01+00:00

This was only added for the drm's fbdev emulation support, so that it
would try harder to show the Oops.

Unfortunately this never really worked reliably, and in practice ended
up pushing the real Oops off the screen due to plentyfull locking,
sleep-while-atomic and other issues. So we removed all that support
from the fbdev emulation a while back. Aside: We've also removed the
kgdb support, for similar reasons.

Since it's such a small patch I figured I don't split this up into the
usual 3-phase removal.

fbdev: add remove_conflicting_pci_framebuffers()

2018-09-03T16:15:40+00:00

Almost all PCI drivers using remove_conflicting_framebuffers() wrap it
with the same code.

v2: add kerneldoc for DRM helper
v3: propagate remove_conflicting_framebuffers() return value
  + move kerneldoc to where function is implemented

fbcon: introduce for_each_registered_fb() helper

2018-07-24T17:11:26+00:00

Following pattern is often used:

 for (i = 0; i < FB_MAX; i++) {
        if (registered_fb[i]) {
                ...
        }
 }

Therefore, as Andy's suggestion, for_each_registered_fb() helper can
be introduced to make the code easier to read and write by reducing
indentation level. It also saves few lines of code in each occurrence.

This patch convert all part here at the same time.

fbdev: arm64 use __raw I/O memory api

2018-01-04T15:53:50+00:00

Since arm64 also has __raw I/O accessors, add __aarch64__ in fb.h.
This is a supplement for commmit 981409b25e2a ("fbdev: arm has __raw
I/O accessors, use them in fb.h").
