zbud pages). The zsmalloc type zpool has a more complex compressed page

Linux NVMe feature and and quirk policy
|
||||
=======================================
|
||||
|
||||
This file explains the policy used to decide what is supported by the
|
||||
Linux NVMe driver and what is not.
|
||||
|
||||
|
||||
Introduction
|
||||
============
|
||||
|
||||
NVM Express is an open collection of standards and information.
|
||||
|
||||
The Linux NVMe host driver in drivers/nvme/host/ supports devices
|
||||
implementing the NVM Express (NVMe) family of specifications, which
|
||||
currently consists of a number of documents:
|
||||
|
||||
- the NVMe Base specification
|
||||
- various Command Set specifications (e.g. NVM Command Set)
|
||||
- various Transport specifications (e.g. PCIe, Fibre Channel, RDMA, TCP)
|
||||
- the NVMe Management Interface specification
|
||||
|
||||
See https://nvmexpress.org/developers/ for the NVMe specifications.
|
||||
|
||||
|
||||
Supported features
|
||||
==================
|
||||
|
||||
NVMe is a large suite of specifications, and contains features that are only
|
||||
useful or suitable for specific use-cases. It is important to note that Linux
|
||||
does not aim to implement every feature in the specification. Every additional
|
||||
feature implemented introduces more code, more maintenance and potentially more
|
||||
bugs. Hence there is an inherent tradeoff between functionality and
|
||||
maintainability of the NVMe host driver.
|
||||
|
||||
Any feature implemented in the Linux NVMe host driver must support the
|
||||
following requirements:
|
||||
|
||||
1. The feature is specified in a release version of an official NVMe
|
||||
specification, or in a ratified Technical Proposal (TP) that is
|
||||
available on NVMe website. Or if it is not directly related to the
|
||||
on-wire protocol, does not contradict any of the NVMe specifications.
|
||||
2. Does not conflict with the Linux architecture, nor the design of the
|
||||
NVMe host driver.
|
||||
3. Has a clear, indisputable value-proposition and a wide consensus across
|
||||
the community.
|
||||
|
||||
Vendor specific extensions are generally not supported in the NVMe host
|
||||
driver.
|
||||
|
||||
It is strongly recommended to work with the Linux NVMe and block layer
|
||||
maintainers and get feedback on specification changes that are intended
|
||||
to be used by the Linux NVMe host driver in order to avoid conflict at a
|
||||
later stage.
|
||||
|
||||
|
||||
Quirks
|
||||
======
|
||||
|
||||
Sometimes implementations of open standards fail to correctly implement parts
|
||||
of the standards. Linux uses identifier-based quirks to work around such
|
||||
implementation bugs. The intent of quirks is to deal with widely available
|
||||
hardware, usually consumer, which Linux users can't use without these quirks.
|
||||
Typically these implementations are not or only superficially tested with Linux
|
||||
by the hardware manufacturer.
|
||||
|
||||
The Linux NVMe maintainers decide ad hoc whether to quirk implementations
|
||||
based on the impact of the problem to Linux users and how it impacts
|
||||
maintainability of the driver. In general quirks are a last resort, if no
|
||||
firmware updates or other workarounds are available from the vendor.
|
||||
|
||||
Quirks will not be added to the Linux kernel for hardware that isn't available

Generally speaking, the patches get triaged quickly (in less than

How do I divide my work into patches?
|
||||
-------------------------------------
|
||||
|
||||
Put yourself in the shoes of the reviewer. Each patch is read separately
|
||||
and therefore should constitute a comprehensible step towards your stated
|
||||
goal.
|
||||
|
||||
Avoid sending series longer than 15 patches. Larger series takes longer
|
||||
to review as reviewers will defer looking at it until they find a large
|
||||
chunk of time. A small series can be reviewed in a short time, so Maintainers
|
||||
just do it. As a result, a sequence of smaller series gets merged quicker and
|
||||
with better review coverage. Re-posting large series also increases the mailing
|
||||
list traffic.
|
||||
|

that can be applied. Do not try to resend just the patches which changed.
|
||||
|
||||
I have received review feedback, when should I post a revised version of the patches?
|
||||
-------------------------------------------------------------------------------------
|
||||
Allow at least 24 hours to pass between postings. This will ensure reviewers
|
||||
from all geographical locations have a chance to chime in. Do not wait
|
||||
too long (weeks) between postings either as it will make it harder for reviewers
|
||||
to recall all the context.
|
||||
Handling misapplied patches
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Make sure you address all the feedback in your new posting. Do not post a new
|
||||
version of the code if the discussion about the previous version is still
|
||||
ongoing, unless directly instructed by a reviewer.
|
||||
|
||||
I submitted multiple versions of a patch series and it looks like a version other than the last one has been accepted, what should I do?
|
||||
----------------------------------------------------------------------------------------------------------------------------------------
|
||||
Occasionally a patch series gets applied before receiving critical feedback,
|
||||
or the wrong version of a series gets applied.
|
||||
There is no revert possible, once it is pushed out, it stays like that.
|
||||
Please send incremental versions on top of what has been merged in order to fix
|
||||
the patches the way they would look like if your latest patch series was to be
|
||||
merged.
|
||||
|
||||
Are there special rules regarding stable submissions on netdev?
|
||||
---------------------------------------------------------------
|
||||
Stable tree
|
||||
~~~~~~~~~~~
|
||||
|
||||
While it used to be the case that netdev submissions were not supposed
|
||||
to carry explicit ``CC: stable@vger.kernel.org`` tags that is no longer
|
||||
the case today. Please follow the standard stable rules in
|
||||
:ref:`Documentation/process/stable-kernel-rules.rst <stable_kernel_rules>`,
|
||||
and make sure you include appropriate Fixes tags!

What is "reverse xmas tree"?
|
||||
----------------------------
|
||||
|
||||
Netdev has a convention for ordering local variables in functions.
|
||||
Order the variable declaration lines longest to shortest, e.g.::
|
||||
|
||||
struct scatterlist *sg;
|
||||
struct sk_buff *skb;
|
||||
int err, i;
|
||||
|
||||
If there are dependencies between the variables preventing the ordering
|
||||
move the initialization out of line.
|
||||
|
||||
I am working in existing code which uses non-standard formatting. Which formatting should I use?
|
||||
------------------------------------------------------------------------------------------------
|
||||
Make your code follow the most recent guidelines, so that eventually all code

||||
in the domain of netdev is in the preferred format.
|
||||
|
||||
I found a bug that might have possible security implications or similar. Should I mail the main netdev maintainer off-list?
|
||||
---------------------------------------------------------------------------------------------------------------------------
|
||||
No. The current netdev maintainer has consistently requested that
|
||||
Do not email netdev maintainers directly if you think you discovered
|
||||
a bug that might have possible security implications.
|
||||
The current netdev maintainer has consistently requested that
|

people use the mailing lists and not reach out directly. If you aren't

OK with that, then perhaps consider mailing security@kernel.org or

reading about http://oss-security.openwall.org/wiki/mailing-lists/distros

||||
as possible alternative mechanisms.
|
||||
|
||||
What level of testing is expected before I submit my change?
|
||||
------------------------------------------------------------
|
||||
At the very minimum your changes must survive an ``allyesconfig`` and an
|
||||
``allmodconfig`` build with ``W=1`` set without new warnings or failures.
|
||||
|
||||
Ideally you will have done run-time testing specific to your change,
|
||||
and the patch series contains a set of kernel selftest for
|
||||
``tools/testing/selftests/net`` or using the KUnit framework.
|
||||
Co-posting changes to user space components
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
You are expected to test your changes on top of the relevant networking
|
||||
tree (``net`` or ``net-next``) and not e.g. a stable tree or ``linux-next``.
|
||||
|
||||
How do I post corresponding changes to user space components?
|
||||
-------------------------------------------------------------
|
||||
User space code exercising kernel features should be posted

alongside kernel patches. This gives reviewers a chance to see

To help maintainers and CI bots you should explicitly mark which tree

your patch is targeting. Assuming that you use git, use the prefix
|
||||

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|

Netdev has a convention for ordering local variables in functions.

Order the variable declaration lines longest to shortest, e.g.::

CPU topology

~~~~~~~~~~~~

|

Several CPUID values include topology information for the host CPU:
|
||||
0x0b and 0x1f for Intel systems, 0x8000001e for AMD systems. Different
|
||||
versions of KVM return different values for this information and userspace
|
||||
should not rely on it. Currently they return all zeroes.
|
||||
|
||||
If userspace wishes to set up a guest topology, it should be careful that
|
||||
the values of these three leaves differ for each CPU. In particular,
|
||||
the APIC ID is found in EDX for all subleaves of 0x0b and 0x1f, and in EAX
|
||||
for 0x8000001e; the latter also encodes the core id and node id in bits

||||
7:0 of EBX and ECX respectively.

This option adds the workaround for ARM Cortex-A715 erratum 2645198.
|
||||
|
||||
If a Cortex-A715 cpu sees a page mapping permissions change from executable
|
||||
to non-executable, it may corrupt the ESR_ELx and FAR_ELx registers on the
|
||||
next instruction abort caused by permission fault.
|
||||
|
||||
Only user-space does executable to non-executable permission transition via
|
||||
mprotect() system call. Workaround the problem by doing a break-before-make
|
||||
TLB invalidation, for all changes to executable user space mappings.
