[Intel-wired-lan] [net-next PATCH 00/25] ice: reorganize virtualization code

[Intel-wired-lan] [net-next PATCH 00/25] ice: reorganize virtualization code

[Jacob Keller]

The ice_virtchnl_pf.c file has become a single place for a lot of
virtualization functionality. This includes most of the virtchnl message
handling, integration with kernel hooks like the .ndo operations, reset
logic, and more.

We are planning in the future to implement and support Scalable IOV in the
ice driver. To do this, much (but not all) of the code in ice_virtchnl_pf.c
will want to be reused.

Rather than dump all of the Scalable IOV implementation into
ice_virtchnl_pf.c it makes sense to house it in a separate file. But that
still leaves all of the Single Root IOV code littered among more generic
logic.

This series reorganizes code to make the non-implementation specific bits
into new files with the following general guidelines:

 * ice_vf_lib.[ch]

   Basic VF structures and accessors. This is where scheme-independent
   code will reside.

 * ice_virtchnl.[ch]

   Virtchnl message handling. This is where the bulk of the logic for
   processing messages from VFs using the virtchnl messaging scheme will
   reside. This is separated from ice_vf_lib.c because it is distinct
   and has a bulk of the processing code.

 * ice_sriov.[ch]

   Single Root IOV implementation, including initialization and the
   routines for interacting with SR-IOV based netdev operations.

 * (future) ice_siov.[ch]

   Scalable IOV implementation.

The goal is to make it easier to re-use parts of the virtualization logic
while separating concerns such as Single Root specific implementation
details.

In addition, this series has several minor cleanups and refactors we've
accumulated during this development cycle which help prepare the ice driver
for the Scalable IOV implementation.

This series builds on top of the recent hash table refactor work.

[Intel-wired-lan] [net-next PATCH 01/25] ice: rename ice_sriov.c to ice_vf_mbx.c

[Jacob Keller]

The ice_sriov.c file primarily contains code which handles the logic for
mailbox overflow detection and some other utility functions related to
the virtualization mailbox.

The bulk of the SR-IOV implementation is actually found in
ice_virtchnl_pf.c, and this file isn't strictly SR-IOV specific.

In the future, the ice driver will support an additional virtualization
scheme known as Scalable IOV, and the code in this file will be used
for this alternative implementation.

Rename this file (and its associated header) to ice_vf_mbx.c, so that we
can later re-use the ice_sriov.c file as the SR-IOV specific file.

[Intel-wired-lan] [net-next PATCH 02/25] ice: rename ice_virtchnl_pf.c to ice_sriov.c

[Jacob Keller]

The ice_virtchnl_pf.c and ice_virtchnl_pf.h files are where most of the
code for implementing Single Root IOV virtualization resides. This code
includes support for bringing up and tearing down VFs, hooks into the
kernel SR-IOV netdev operations, and for handling virtchnl messages from
VFs.

In the future, we plan to support Scalable IOV in addition to Single
Root IOV as an alternative virtualization scheme. This implementation
will re-use some but not all of the code in ice_virtchnl_pf.c

To prepare for this future, we want to refactor and split up the code in
ice_virtchnl_pf.c into the following scheme:

 * ice_vf_lib.[ch]

   Basic VF structures and accessors. This is where scheme-independent
   code will reside.

 * ice_virtchnl.[ch]

   Virtchnl message handling. This is where the bulk of the logic for
   processing messages from VFs using the virtchnl messaging scheme will
   reside. This is separated from ice_vf_lib.c because it is distinct
   and has a bulk of the processing code.

 * ice_sriov.[ch]

   Single Root IOV implementation, including initialization and the
   routines for interacting with SR-IOV based netdev operations.

 * (future) ice_siov.[ch]

   Scalable IOV implementation.

As a first step, lets assume that all of the code in
ice_virtchnl_pf.[ch] is for Single Root IOV. Rename this file to
ice_sriov.c and its header to ice_sriov.h

Future changes will further split out the code in these files following
the plan outlined here.

[Intel-wired-lan] [net-next PATCH 03/25] ice: remove circular header dependencies on ice.h

[Jacob Keller]

Several headers in the ice driver include ice.h even though they are
themselves included by that header. The most notable of these is
ice_common.h, but several other headers also do this.

Such a recursive inclusion is problematic as it forces headers to be
included in a strict order, otherwise compilation errors can result. The
circular inclusions do not trigger an endless loop due to standard
header inclusion guards, however other errors can occur.

For example, ice_flow.h defines ice_rss_hash_cfg, which is used by
ice_sriov.h as part of the definition of ice_vf_hash_ip_ctx.

ice_flow.h includes ice_acl.h, which includes ice_common.h, and which
finally includes ice.h. Since ice.h itself includes ice_sriov.h, this
creates a circular dependency.

The definition in ice_sriov.h requires things from ice_flow.h, but
ice_flow.h itself will lead to trying to load ice_sriov.h as part of its
process for expanding ice.h. The current code avoids this issue by
having an implicit dependency without the include of ice_flow.h.

If we were to fix that so that ice_sriov.h explicitly depends on
ice_flow.h the following pattern would occur:

  ice_flow.h -> ice_acl.h -> ice_common.h -> ice.h -> ice_sriov.h

At this point, during the expansion of, the header guard for ice_flow.h
is already set, so when ice_sriov.h attempts to load the ice_flow.h
header it is skipped. Then, we go on to begin including the rest of
ice_sriov.h, including structure definitions which depend on
ice_rss_hash_cfg. This produces a compiler warning because
ice_rss_hash_cfg hasn't yet been included. Remember, we're just at the
start of ice_flow.h!

If the order of headers is incorrect (ice_flow.h is not implicitly
loaded first in all files which include ice_sriov.h) then we get the
same failure.

Removing this recursive inclusion requires fixing a few cases where some
headers depended on the header inclusions from ice.h. In addition, a few
other changes are also required.

Most notably, ice_hw_to_dev is implemented as a macro in ice_osdep.h,
which is the likely reason that ice_common.h includes ice.h at all. This
macro implementation requires the full definition of ice_pf in order to
properly compile.

Fix this by moving it to a function declared in ice_main.c, so that we
do not require all files to depend on the layout of the ice_pf
structure.

Note that this change only fixes circular dependencies, but it does not
fully resolve all implicit dependencies where one header may depend on
the inclusion of another. I tried to fix as many of the implicit
dependencies as I noticed, but fixing them all requires a somewhat
tedious analysis of each header and attempting to compile it separately.

[Intel-wired-lan] [net-next PATCH 04/25] ice: convert vf->vc_ops to a const pointer

[Jacob Keller]

The vc_ops structure is used to allow different handlers for virtchnl
commands when the driver is in representor mode. The current
implementation uses a copy of the ops table in each VF, and modifies
this copy dynamically.

The usual practice in kernel code is to store the ops table in a
constant structure and point to different versions. This has a number of
advantages:

  1. Reduced memory usage. Each VF merely points to the correct table,
     so they're able to re-use the same contsnat lookup table in memory.
  2. Consistency. It becomes more difficult to accidentally update or
     edit only one op call. Instead, the code switches to the correct
     able by a single pointer write. In general this is atomic, either
     the pointer is updated or its not.
  3. Code Layout. The VF structure can store a pointer to the table
     without needing to have the full structure definition defined prior
     to the VF structure definition. This will aid in future refactoring
     of code by allowing the VF pointer to be kept in ice_vf_lib.h while
     the virtchnl ops table can be maintained in ice_virtchnl.h

There is one major downside in the case of the vc_ops structure. Most of
the operations in the table are the same between the two current
implementations. This can appear to lead to duplication since each
implementation must now fill in the complete table. It could make
spotting the differences in the representor mode more challenging.
Unfortunately, methods to make this less error prone either add
complexity overhead (macros using CPP token concatenation) or don't work
on all compilers we support (constant initializer from another constant
structure).

The cost of maintaining two structures does not out weigh the benefits
of the constant table model.

While we're making these changes, go ahead and rename the structure and
implementations with "virtchnl" instead of "vc_vf_". This will more
closely align with the planned file renaming, and avoid similar names when
we later introduce a "vf ops" table for separating Scalable IOV and
Single Root IOV implementations.

Leave the accessor/assignment functions in order to avoid issues with
compiling with options disabled. The interface makes it easier to handle
when CONFIG_PCI_IOV is disabled in the kernel.

[Intel-wired-lan] [net-next PATCH 05/25] ice: remmove unused definitions from ice_sriov.h

[Jacob Keller]

A few more macros exist in ice_sriov.h which are not used anywhere.
These can be safely removed. Note that ICE_VIRTCHNL_VF_CAP_L2 capability
is set but never checked anywhere in the driver. Thus it is also safe to
remove.

[Intel-wired-lan] [net-next PATCH 06/25] ice: rename ICE_MAX_VF_COUNT to avoid confusion

[Jacob Keller]

The ICE_MAX_VF_COUNT field is defined in ice_sriov.h. This count is true
for SR-IOV but will not be true for all VF implementations, such as when

[Intel-wired-lan] [net-next PATCH 07/25] ice: refactor spoofchk control code in ice_sriov.c

[Jacob Keller]

The API to control the VSI spoof checking for a VF VSI has three
functions: enable, disable, and set. The set function takes the VSI and
the VF and decides whether to call enable or disable based on the
vf->spoofchk field.

In some flows, vf->spoofchk is not yet set, such as the function used to
control the setting for a VF. (vf->spoofchk is only updated after a
success).

Simplify this API by refactoring ice_vf_set_spoofchk_cfg to be
"ice_vsi_apply_spoofchk" which takes the boolean and allows all callers
to avoid having to determine whether to call enable or disable
themselves.

This matches the expected callers better, and will prevent the need to
export more than one function when this code must be called from another
file.

[Jacob Keller]

The ice_set_vf_port_vlan function is located in ice_sriov.c very far
away from the other .ndo operations that it is similar to. Move this so
that its located near the other .ndo operation definitions.

[Intel-wired-lan] [net-next PATCH 09/25] ice: cleanup error logging for ice_ena_vfs

[Jacob Keller]

The ice_ena_vfs function and some of its sub-functions like
ice_set_per_vf_res use a "if (<function>) { <print error> ; <exit> }"
flow. This flow discards specialized errors reported by the called
function.

This style is generally not preferred as it makes tracing error sources
more difficult. It also means we cannot log the actual error received
properly.

Refactor several calls in the ice_ena_vfs function that do this to catch
the error in the 'ret' variable. Report this in the messages, and then
return the more precise error value.

Doing this reveals that ice_set_per_vf_res returns -EINVAL or -EIO in
places where -ENOSPC makes more sense. Fix these calls up to return the
more appropriate value.

[Intel-wired-lan] [net-next PATCH 12/25] ice: introduce ice_vf_lib.c, ice_vf_lib.h, and ice_vf_lib_private.h

[Jacob Keller]

Introduce the ice_vf_lib.c file along with the ice_vf_lib.h and
ice_vf_lib_private.h header files.

These files will house the generic VF structures and access functions.
Move struct ice_vf and its dependent definitions into this new header
file.

The ice_vf_lib.c is compiled conditionally on CONFIG_PCI_IOV. Some of
its functionality is required by all driver files. However, some of its
functionality will only be required by other files also conditionally
compiled based on CONFIG_PCI_IOV.

Declaring these functions used only in CONFIG_PCI_IOV files in
ice_vf_lib.h is verbose. This is because we must provide a fallback
implementation for each function in this header since it is included in
files which may not be compiled with CONFIG_PCI_IOV.

Instead, introduce a new ice_vf_lib_private.h header which verifies that
CONFIG_PCI_IOV is enabled. This header is intended to be directly
included in .c files which are CONFIG_PCI_IOV only. Add a #error
indication that will complain if the file ever gets included by another
C file on a kernel with CONFIG_PCI_IOV disabled. Add a comment
indicating the nature of the file and why it is useful.

This makes it so that we can easily define functions exposed from
ice_vf_lib.c into other virtualization files without needing to add
fallback implementations for every single function.

This begins the path to separate out generic code which will be reused
by other virtualization implementations from ice_sriov.h and ice_sriov.c

If we fail to clear the malicious VF indication after a VF reset, the
dev_dbg message which is printed uses the local variable 'i' when it
meant to use vf->vf_id. Fix this.

[Intel-wired-lan] [net-next PATCH 14/25] ice: introduce VF operations structure for reset flows

[Jacob Keller]

The ice driver currently supports virtualization using Single Root IOV,
with code in the ice_sriov.c file. In the future, we plan to also
implement support for Scalable IOV, which uses slightly different
hardware implementations for some functionality.

To eventually allow this, we introduce a new ice_vf_ops structure which
will contain the basic operations that are different between the two IOV
implementations. This primarily includes logic for how to handle the VF
reset registers, as well as what to do before and after rebuilding the
VF's VSI.

Implement these ops structures and call the ops table instead of
directly calling the SR-IOV specific function. This will allow us to
easily add the Scalable IOV implementation in the future. Additionally,
it helps separate the generalized VF logic from SR-IOV specifics. This
change allows us to move the reset logic out of ice_sriov.c and into
ice_vf_lib.c without placing any Single Root specific details into the
generic file.

[Intel-wired-lan] [net-next PATCH 15/25] ice: fix a long line warning in ice_reset_vf

[Jacob Keller]

We're about to move ice_reset_vf out of ice_sriov.c and into
ice_vf_lib.c

One of the dev_err statements has a checkpatch.pl violation due to
putting the vf->vf_id on the same line as the dev_err. Fix this style
issue first before moving the code.

[Intel-wired-lan] [net-next PATCH 16/25] ice: move reset functionality into ice_vf_lib.c

[Jacob Keller]

Now that the reset functions do not rely on Single Root specific
behavior, move the ice_reset_vf, ice_reset_all_vfs, and
ice_vf_rebuild_host_cfg functions and their dependent helper functions
out of ice_sriov.c and into ice_vf_lib.c

[Intel-wired-lan] [net-next PATCH 17/25] ice: drop is_vflr parameter from ice_reset_all_vfs

[Jacob Keller]

The ice_reset_all_vfs function takes a parameter to handle whether its
operating after a VFLR event or not. This is not necessary as every
caller always passes true. Simplify the interface by removing the
parameter.

[Intel-wired-lan] [net-next PATCH 18/25] ice: make ice_reset_all_vfs void

[Jacob Keller]

The ice_reset_all_vfs function returns true if any VFs were reset, and
false otherwise. However, no callers check the return value.

Drop this return value and make the function void since the callers do
not care about this.

[Intel-wired-lan] [net-next PATCH 19/25] ice: convert ice_reset_vf to standard error codes

[Jacob Keller]

The ice_reset_vf function returns a boolean value indicating whether or
not the VF reset. This is a bit confusing since it means that callers
need to know how to interpret the return value when needing to indicate
an error.

Refactor the function and call sites to report a regular error code. We
still report success (i.e. return 0) in cases where the reset is in
progress or is disabled.

Existing callers don't care because they do not check the return value.
We keep the error code anyways instead of a void return because we
expect future code which may care about or at least report the error
value.

[Intel-wired-lan] [net-next PATCH 20/25] ice: convert ice_reset_vf to take flags

[Jacob Keller]

The ice_reset_vf function takes a boolean parameter which indicates
whether or not the reset is due to a VFLR event.

This is somewhat confusing to read because readers must interpret what
"true" and "false" mean when seeing a line of code like
"ice_reset_vf(vf, false)".

We will want to add another toggle to the ice_reset_vf in a following
change. To avoid proliferating many arguments, convert this function to
take flags instead. ICE_VF_RESET_VFLR will indicate if this is a VFLR
reset. A value of 0 indicates no flags.

One could argue that "ice_reset_vf(vf, 0)" is no more readable than
"ice_reset_vf(vf, false)".. However, this type of flags interface is
somewhat common and using 0 to mean "no flags" makes sense in this
context. We could bother to add a define for "ICE_VF_RESET_PLAIN" or
something similar, but this can be confusing since its not an actual bit
flag.

This paves the way to add another flag to the function in a following
change.

[Intel-wired-lan] [net-next PATCH 21/25] ice: introduce ICE_VF_RESET_NOTIFY flag

[Jacob Keller]

In some cases of resetting a VF, the PF would like to first notify the
VF that a reset is impending. This is currently done via
ice_vc_notify_vf_reset. A wrapper to ice_reset_vf, ice_vf_reset_vf, is
used to call this function first before calling ice_reset_vf.

In fact, every single call to ice_vc_notify_vf_reset occurs just prior
to a call to ice_vc_reset_vf.

Now that ice_reset_vf has flags, replace this separate call with an
ICE_VF_RESET_NOTIFY flag. This removes an unnecessary exported function
of ice_vc_notify_vf_reset, and also makes there be a single function to
reset VFs (ice_reset_vf).

[Intel-wired-lan] [net-next PATCH 22/25] ice: introduce ICE_VF_RESET_LOCK flag

[Jacob Keller]

The ice_reset_vf function performs actions which must be taken only
while holding the VF configuration lock. Some flows already acquired the
lock, while other flows must acquire it just for the reset function. Add
the ICE_VF_RESET_LOCK flag to the function so that it can handle taking
and releasing the lock instead at the appropriate scope.

[Intel-wired-lan] [net-next PATCH 23/25] ice: cleanup long longs in ice_sriov.c

[Jacob Keller]

Before we move the virtchnl message handling from ice_sriov.c into
ice_virtchnl.c, cleanup some long line warnings to avoid checkpatch.pl
complaints.

[Intel-wired-lan] [net-next PATCH 25/25] ice: remove PF pointer from ice_check_vf_init

[Jacob Keller]

The ice_check_vf_init function takes both a PF and a VF pointer. Every
caller looks up the PF pointer from the VF structure. Some callers only
use of the PF pointer is call this function. Move the lookup inside
ice_check_vf_init and drop the unnecessary argument.

Cleanup the callers to drop the now unnecessary local variables. In
particular, replace the local PF pointer with a HW structure pointer in
ice_vc_get_vf_res_msg which simplifies a few accesses to the HW
structure in that function.

Yea, I'll fix that up in the tree.

[Intel-wired-lan] [net-next PATCH 04/25] ice: convert vf->vc_ops to a const pointer

[Intel-wired-lan] [net-next PATCH 02/25] ice: rename ice_virtchnl_pf.c to ice_sriov.c

> The ice_virtchnl_pf.c and ice_virtchnl_pf.h files are where most of the code
> for implementing Single Root IOV virtualization resides. This code includes
> support for bringing up and tearing down VFs, hooks into the kernel SR-IOV
> netdev operations, and for handling virtchnl messages from VFs.
> 
> In the future, we plan to support Scalable IOV in addition to Single Root IOV
> as an alternative virtualization scheme. This implementation will re-use some
> but not all of the code in ice_virtchnl_pf.c
> 
> To prepare for this future, we want to refactor and split up the code in
> ice_virtchnl_pf.c into the following scheme:
> 
>  * ice_vf_lib.[ch]
> 
>    Basic VF structures and accessors. This is where scheme-independent
>    code will reside.
> 
>  * ice_virtchnl.[ch]
> 
>    Virtchnl message handling. This is where the bulk of the logic for
>    processing messages from VFs using the virtchnl messaging scheme will
>    reside. This is separated from ice_vf_lib.c because it is distinct
>    and has a bulk of the processing code.
> 
>  * ice_sriov.[ch]
> 
>    Single Root IOV implementation, including initialization and the
>    routines for interacting with SR-IOV based netdev operations.
> 
>  * (future) ice_siov.[ch]
> 
>    Scalable IOV implementation.
> 
> As a first step, lets assume that all of the code in ice_virtchnl_pf.[ch] is for
> Single Root IOV. Rename this file to ice_sriov.c and its header to ice_sriov.h
> 
> Future changes will further split out the code in these files following the plan
> outlined here.
