Add a GPIO lookup entry and a device property for GPIO backlight to the
board file. Tie them to the platform device which is now registered using
platform_device_register_full() because of the properties. These changes
are inactive now but will be used once the gpio backlight driver is
modified.

The GPIO backlight driver currently requests the line 'as is', without
acively setting its direction. This can lead to problems: if the line
is in input mode by default, we won't be able to drive it later when
updating the status and also reading its initial value doesn't make
sense for backlight setting.
Request the line 'as is' initially, so that we can read its value
without affecting it but then change the direction to output explicitly
when setting the initial brightness.
Also: check the current direction and only read the value if it's output.

The auto string detection algorithm checks if the current WLED
sink configuration is valid. It tries enabling every sink and
checks if the OVP fault is observed. Based on this information
it detects and enables the valid sink configuration.
Auto calibration will be triggered when the OVP fault interrupts
are seen frequently thereby it tries to fix the sink configuration.
The auto-detection also kicks in when the connected LED string
of the display-backlight malfunctions (because of damage) and
requires the damaged string to be turned off to prevent the
complete panel and/or board from being damaged.

Using a power-of-2 instead of power-of-10 base makes the computations
much cheaper. 2^16 is safe; retval never becomes more than 2^48 +
2^32/2. On a 32 bit platform, the very expensive 64/32 division at the
end of cie1931() instead becomes essentially free (a shift by 32 is

The "break-even" point for the two formulas is L==8, which is also
what the code actually implements. [Incidentally, at that point one
has Y=0.008856, not 0.08856].
Moreover, all the sources I can find say the linear factor is 903.3
rather than 902.3, which makes sense since then the formulas agree at
L==8, both yielding the 0.008856 figure to four significant digits.

Merge active entropy generation updates.
This is admittedly partly "for discussion". We need to have a way
forward for the boot time deadlocks where user space ends up waiting for
more entropy, but no entropy is forthcoming because the system is
entirely idle just waiting for something to happen.
While this was triggered by what is arguably a user space bug with
GDM/gnome-session asking for secure randomness during early boot, when
they didn't even need any such truly secure thing, the issue ends up
being that our "getrandom()" interface is prone to that kind of
confusion, because people don't think very hard about whether they want
to block for sufficient amounts of entropy.
The approach here-in is to decide to not just passively wait for entropy
to happen, but to start actively collecting it if it is missing. This
is not necessarily always possible, but if the architecture has a CPU
cycle counter, there is a fair amount of noise in the exact timings of
reasonably complex loads.
We may end up tweaking the load and the entropy estimates, but this
should be at least a reasonable starting point.
As part of this, we also revert the revert of the ext4 IO pattern
improvement that ended up triggering the reported lack of external
entropy.
* getrandom() active entropy waiting:
Revert "Revert "ext4: make __ext4_get_inode_loc plug""
random: try to actively add entropy rather than passively wait for it
|
|
This reverts commit 72dbcf72156641fde4d8ea401e977341bfd35a05.
Instead of waiting forever for entropy that may just not happen, we now
try to actively generate entropy when required, and are thus hopefully
avoiding the problem that caused the nice ext4 IO pattern fix to be
reverted.
So revert the revert.

For 5.3 we had to revert a nice ext4 IO pattern improvement, because it
caused a bootup regression due to lack of entropy at bootup together
with arguably broken user space that was asking for secure random
numbers when it really didn't need to.
See commit 72dbcf721566 (Revert "ext4: make __ext4_get_inode_loc plug").
This aims to solve the issue by actively generating entropy noise using
the CPU cycle counter when waiting for the random number generator to
initialize. This only works when you have a high-frequency time stamp
counter available, but that's the case on all modern x86 CPU's, and on
most other modern CPU's too.
What we do is to generate jitter entropy from the CPU cycle counter
under a somewhat complex load: calling the scheduler while also
guaranteeing a certain amount of timing noise by also triggering a
timer.
I'm sure we can tweak this, and that people will want to look at other
alternatives, but there's been a number of papers written on jitter
entropy, and this should really be fairly conservative by crediting one
bit of entropy for every timer-induced jump in the cycle counter. Not
because the timer itself would be all that unpredictable, but because
the interaction between the timer and the loop is going to be.
Even if (and perhaps particularly if) the timer actually happens on
another CPU, the cacheline interaction between the loop that reads the
cycle counter and the timer itself firing is going to add perturbations
to the cycle counter values that get mixed into the entropy pool.
As Thomas pointed out, with a modern out-of-order CPU, even quite simple
loops show a fair amount of hard-to-predict timing variability even in
the absense of external interrupts. But this tries to take that further
by actually having a fairly complex interaction.
This is not going to solve the entropy issue for architectures that have
no CPU cycle counter, but it's not clear how (and if) that is solvable,
and the hardware in question is largely starting to be irrelevant. And
by doing this we can at least avoid some of the even more contentious
approaches (like making the entropy waiting time out in order to avoid
the possibly unbounded waiting).

Pull thermal SoC updates from Eduardo Valentin:
"This is a really small pull in the midst of a lot of pending patches.
We are in the middle of restructuring how we are maintaining the
thermal subsystem, as per discussion in our last LPC. For now, I am
sending just some changes that were pending in my tree. Looking
forward to get a more streamlined process in the next merge window"
* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal:
thermal: db8500: Rewrite to be a pure OF sensor
thermal: db8500: Use dev helper variable
thermal: db8500: Finalize device tree conversion
thermal: thermal_mmio: remove some dead code

Pull more i2c updates from Wolfram Sang:
- make Lenovo Yoga C630 boot now that the dependencies are merged
- restore BlockProcessCall for i801, accidently removed in this merge
window
- a bugfix for the riic driver
- an improvement to the slave-eeprom driver which should have been in
the first pull request but sadly got lost in the process
* 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
i2c: slave-eeprom: Add read only mode
i2c: i801: Bring back Block Process Call support for certain platforms
i2c: riic: Clear NACK in tend isr
i2c: qcom-geni: Disable DMA processing on the Lenovo Yoga C630

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu fixes from Joerg Roedel:
"A couple of fixes for the AMD IOMMU driver have piled up:
- Some fixes for the reworked IO page-table which caused memory leaks
or did not allow to downgrade mappings under some conditions.
- Locking fixes to fix a couple of possible races around accessing
'struct protection_domain'. The races got introduced when the
dma-ops path became lock-less in the fast-path"
* tag 'iommu-fixes-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu:
iommu/amd: Lock code paths traversing protection_domain->dev_list
iommu/amd: Lock dev_data in attach/detach code paths
iommu/amd: Check for busy devices earlier in attach_device()
iommu/amd: Take domain->lock for complete attach/detach path
iommu/amd: Remove amd_iommu_devtable_lock
iommu/amd: Remove domain->updated
iommu/amd: Wait for completion of IOTLB flush in attach_device
iommu/amd: Unmap all L7 PTEs when downgrading page-sizes
iommu/amd: Introduce first_pte_l7() helper
iommu/amd: Fix downgrading default page-sizes in alloc_pte()
iommu/amd: Fix pages leak in free_pagetable()

The role of the contact list provided by the disclosing party and how it
affects the disclosure process and the ability to include experts into
the development process is not really well explained.
Neither is it entirely clear when the disclosing party will be informed
about the fact that a developer who is not covered by an employer NDA needs
to be brought in and disclosed.
Explain the role of the contact list and the information policy along with
an eventual conflict resolution better.
