The docs we had for drm_dp_aux_init() and drm_dp_aux_register() were mostly

non-NULL until drm_dp_aux_register() has been called. We make sure to point

drm/bochs: Add screen blanking support
On bochs DRM driver, the execution of "setterm --blank force" results
in a frozen screen instead of a blank screen. It's due to the lack of
the screen blanking support in its code.
Actually, the QEMU bochs vga side can switch to the blanking mode when
the bit 0x20 is cleared on VGA_ATT_IW register (0x3c0), which updates
ar_index in QEMU side. So, essentially, we'd just need to clear the
bit at pipe disable callback; that's what this patch does essentially.
However, a tricky part is that the access via VGA_ATT_IW is done in
"flip-flop"; the first write is for index and the second write is for
the data like palette. Meanwhile, in the current bochs DRM driver,
the flip-flop wasn't considered, and it calls only the register update
once with the value 0x20.
The spec and the actual VGA implementation in QEMU suggests that the
flip flop flag is discarded by reading the CRTC index register
(VGA_IS1_RC, 0x3da). So, in this patch, we add the helper to read a
byte and the call to clear the flip flop flag before changing the
blank / unblank setup via VGA_ATT_IW register.
v1->v2:
* discard ar_flip_flop by reading 0x3da, add bochs_vga_readb()
* include video/vga.h for VGA register definitions
* move the blank/unblank code to bochs_hw_blank()

The reason is the DP501's FW is mapped to BMC addressing space rather

The resolution is that using "pci_iomap_range()" maps to DP501's FW that

drm/panel: panel-simple: Use runtime pm to avoid excessive unprepare / prepare
Unpreparing and re-preparing a panel can be a really heavy
operation. Panels datasheets often specify something on the order of
500ms as the delay you should insert after turning off the panel
before turning it on again. In addition, turning on a panel can have
delays on the order of 100ms - 200ms before the panel will assert HPD
(AKA "panel ready"). The above means that we should avoid turning a
panel off if we're going to turn it on again shortly.
The above becomes a problem when we want to read the EDID of a
panel. The way that ordering works is that userspace wants to read the
EDID of the panel _before_ fully enabling it so that it can set the
initial mode correctly. However, we can't read the EDID until we power
it up. This leads to code that does this dance (like
ps8640_bridge_get_edid()):
1. When userspace requests EDID / the panel modes (through an ioctl),
we power on the panel just enough to read the EDID and then power
it off.
2. Userspace then turns the panel on.
There's likely not much time between step #1 and #2 and so we want to
avoid powering the panel off and on again between those two steps.
Let's use Runtime PM to help us. We'll move the existing prepare() and
unprepare() to be runtime resume() and runtime suspend(). Now when we
want to prepare() or unprepare() we just increment or decrement the
refcount. We'll default to a 1 second autosuspend delay which seems
sane given the typical delays we see for panels.
A few notes:
- It seems the existing unprepare() and prepare() are defined to be
no-ops if called extra times. We'll preserve that behavior but may
try to remove it in a future patch.
- This is a slight change in the ABI of simple panel. If something was
absolutely relying on the unprepare() to happen instantly that
simply won't be the case anymore. I'm not aware of anyone relying on
that behavior, but if there is someone then we'll need to figure out
how to enable (or disable) this new delayed behavior selectively.
- In order for this to work we now have a hard dependency on
"PM". From memory this is a legit thing to assume these days and we
don't have to find some fallback to keep working if someone wants to
build their system without "PM".

Platform devices might operate on firmware framebuffers, such as VESA

the device, it has to remove any platform driver that operates on the

native drivers to remove the generic ones.
For now, this only concerns generic fbdev drivers. Code for removing
these is provided by drm_fb_helper_remove_conflicting_framebuffers() et
al. Simply wrap these functions for now. At a later point, code can be

"One more patch that we'd like to get to 5.12 before release.
It's changing where and how the superblock is stored in the zoned
mode. It is an on-disk format change but so far there are no
implications for users as the proper mkfs support hasn't been merged
and is waiting for the kernel side to settle.
Until now, the superblocks were derived from the zone index, but zone
size can differ per device. This is changed to be based on fixed
offset values, to make it independent of the device zone size.
The work on that got a bit delayed, we discussed the exact locations
to support potential device sizes and usecases. (Partially delayed
also due to my vacation.) Having that in the same release where the
zoned mode is declared usable is highly desired, there are userspace
projects that need to be updated to recognize the feature. Pushing
that to the next release would make things harder to test"

Merge branch 'for-5.12-fixes' of git://git./linux/kernel/git/dennis/percpu
Pull percpu fix from Dennis Zhou:
"This contains a fix for sporadically failing atomic percpu
allocations.
I only caught it recently while I was reviewing a new series [1] and
simultaneously saw reports by btrfs in xfstests [2] and [3].
In v5.9, memcg accounting was extended to percpu done by adding a
second type of chunk. I missed an interaction with the free page float
count used to ensure we can support atomic allocations. If one type of
chunk has no free pages, but the other has enough to satisfy the free
page float requirement, we will not repopulate the free pages for the
former type of chunk. This led to the sporadically failing atomic
allocations"
