Patrik Fimml [Wed, 2 Dec 2020 22:42:04 +0000 (14:42 -0800)]
Input: Add "inhibited" property
Userspace might want to implement a policy to temporarily disregard input
from certain devices, including not treating them as wakeup sources.
An example use case is a laptop, whose keyboard can be folded under the
screen to create tablet-like experience. The user then must hold the laptop
in such a way that it is difficult to avoid pressing the keyboard keys. It
is therefore desirable to temporarily disregard input from the keyboard,
until it is folded back. This obviously is a policy which should be kept
out of the kernel, but the kernel must provide suitable means to implement
such a policy.
This patch adds a sysfs interface for exactly this purpose.
To implement the said interface it adds an "inhibited" property to struct
input_dev, and effectively creates four states a device can be in: closed
uninhibited, closed inhibited, open uninhibited, open inhibited. It also
defers calling driver's ->open() and ->close() to until they are actually
needed, e.g. it makes no sense to prepare the underlying device for
generating events (->open()) if the device is inhibited.
uninhibit
closed <------------ closed
uninhibited ------------> inhibited
| ^ inhibit | ^
1st | | 1st | |
open | | open | |
| | | |
| | last | | last
| | close | | close
v | uninhibit v |
open <------------ open
uninhibited ------------> inhibited
The top inhibit/uninhibit transition happens when users == 0.
The bottom inhibit/uninhibit transition happens when users > 0.
The left open/close transition happens when !inhibited.
The right open/close transition happens when inhibited.
Due to all transitions being serialized with dev->mutex, it is impossible
to have "diagonal" transitions between closed uninhibited and open
inhibited or between open uninhibited and closed inhibited.
No new callbacks are added to drivers, because their open() and close()
serve exactly the purpose to tell the driver to start/stop providing
events to the input core. Consequently, open() and close() - if provided
- are called in both inhibit and uninhibit paths.

as GPIO_ACTIVE_HIGH and the driver then applies the reverse action by
driving the line low (setting to 0) to enter reset state and driving the
line high (setting to 1) to get out of reset state.
The correct way to handle active low GPIO lines is to provide the
GPIO_ACTIVE_LOW in the device tree (thus properly describing the hardware)
and letting the GPIO framework invert the assertion (driving high) to a
low level and vice versa.
This is considered a bug since the device trees are incorrectly

There have been elusive reports of filemap_fault() hitting its
VM_BUG_ON_PAGE(page_to_pgoff(page) != offset, page) on kernels built
with CONFIG_READ_ONLY_THP_FOR_FS=y.
Suren has hit it on a kernel with CONFIG_READ_ONLY_THP_FOR_FS=y and
CONFIG_NUMA is not set: and he has analyzed it down to how khugepaged
without NUMA reuses the same huge page after collapse_file() failed
(whereas NUMA targets its allocation to the respective node each time).
And most of us were usually testing with CONFIG_NUMA=y kernels.
An initial patch replaced __SetPageLocked() by lock_page(), which did
fix the race which Suren illustrates above. But testing showed that it's
not good enough: if the racing task's __lock_page() gets delayed long
after its find_get_page(), then it may follow collapse_file(new start)'s
successful final unlock_page(), and crash on the same VM_BUG_ON_PAGE.
It could be fixed by relaxing filemap_fault()'s VM_BUG_ON_PAGE to a
check and retry (as is done for mapping), with similar relaxations in
find_lock_entry() and pagecache_get_page(): but it's not obvious what
else might get caught out; and khugepaged non-NUMA appears to be unique
in exposing a page to page cache, then revoking, without going through
a full cycle of freeing before reuse.
Instead, non-NUMA khugepaged_prealloc_page() release the old page
if anyone else has a reference to it (1% of cases when I tested).
Although never reported on huge tmpfs, I believe its find_lock_entry()
has been at similar risk; but huge tmpfs does not rely on khugepaged
for its normal working nearly so much as READ_ONLY_THP_FOR_FS does.
When the NACK and BUS error bits are set by the hardware, the driver is
responsible for clearing them by writing "1" into the corresponding
status registers.
Hence perform the necessary operations in owl_i2c_interrupt().
