Writeback
=========
Page cache is dirtied through buffered writes and shared mmaps and
written asynchronously to the backing filesystem by the writeback
mechanism. Writeback sits between the memory and IO domains and
regulates the proportion of dirty memory by balancing dirtying and
write IOs.
On traditional cgroup hierarchies, relationships between different
controllers cannot be established making it impossible for writeback
to operate accounting for cgroup resource restrictions and all
writeback IOs are attributed to the root cgroup.
If both the blkio and memory controllers are used on the v2 hierarchy
and the filesystem supports cgroup writeback, writeback operations
correctly follow the resource restrictions imposed by both memory and
blkio controllers.
Writeback examines both system-wide and per-cgroup dirty memory status
and enforces the more restrictive of the two. Also, writeback control
parameters which are absolute values - vm.dirty_bytes and
vm.dirty_background_bytes - are distributed across cgroups according
to their current writeback bandwidth.
There's a peculiarity stemming from the discrepancy in ownership
granularity between memory controller and writeback. While memory
controller tracks ownership per page, writeback operates on inode
basis. cgroup writeback bridges the gap by tracking ownership by
inode but migrating ownership if too many foreign pages, pages which
don't match the current inode ownership, have been encountered while
writing back the inode.
This is a conscious design choice as writeback operations are
inherently tied to inodes making strictly following page ownership
complicated and inefficient. The only use case which suffers from
this compromise is multiple cgroups concurrently dirtying disjoint
regions of the same inode, which is an unlikely use case and decided
to be unsupported. Note that as memory controller assigns page
ownership on the first use and doesn't update it until the page is
released, even if cgroup writeback strictly follows page ownership,
multiple cgroups dirtying overlapping areas wouldn't work as expected.
In general, write-sharing an inode across multiple cgroups is not well
supported.
Filesystem support for cgroup writeback
---------------------------------------
A filesystem can make writeback IOs cgroup-aware by updating
address_space_operations->writepage[s]() to annotate bio's using the
following two functions.
* wbc_init_bio(@wbc, @bio)
Should be called for each bio carrying writeback data and associates
the bio with the inode's owner cgroup. Can be called anytime
between bio allocation and submission.
* wbc_account_io(@wbc, @page, @bytes)
Should be called for each data segment being written out. While
this function doesn't care exactly when it's called during the
writeback session, it's the easiest and most natural to call it as
data segments are added to a bio.
With writeback bio's annotated, cgroup support can be enabled per
super_block by setting MS_CGROUPWB in ->s_flags. This allows for
selective disabling of cgroup writeback support which is helpful when
certain filesystem features, e.g. journaled data mode, are
incompatible.
wbc_init_bio() binds the specified bio to its cgroup. Depending on
the configuration, the bio may be executed at a lower priority and if
the writeback session is holding shared resources, e.g. a journal
entry, may lead to priority inversion. There is no one easy solution
for the problem. Filesystems can try to work around specific problem
cases by skipping wbc_init_bio() or using bio_associate_blkcg()
directly.

The dynamic power consumption of the CPU is

Binding for ST's CPUFreq driver
===============================
ST's CPUFreq driver attempts to read 'process' and 'version' attributes
from the SoC, then supplies the OPP framework with 'prop' and 'supported
hardware' information respectively. The framework is then able to read
the DT and operate in the usual way.
For more information about the expected DT format [See: ../opp/opp.txt].

supported by the OPP. For example: a platform with hierarchy of three levels
of versions (A, B and C), this field should be like <X Y Z>, where X
corresponds to Version hierarchy A, Y corresponds to version hierarchy B and Z
corresponds to version hierarchy C.
Each level of hierarchy is represented by a 32 bit value, and so there can be
only 32 different supported version per hierarchy. i.e. 1 bit per version. A
value of 0xFFFFFFFF will enable the OPP for all versions for that hierarchy
level. And a value of 0x00000000 will disable the OPP completely, and so we
never want that to happen.
If 32 values aren't sufficient for a version hierarchy, than that version
hierarchy can be contained in multiple 32 bit values. i.e. <X Y Z1 Z2> in the
above example, Z1 & Z2 refer to the version hierarchy Z.
