Moshe Shemesh says:
====================
Add devlink reload action and limit options
Introduce new options on devlink reload API to enable the user to select
the reload action required and constrains limits on these actions that he
may want to ensure. Complete support for reload actions in mlx5.
The following reload actions are supported:
driver_reinit: driver entities re-initialization, applying devlink-param
and devlink-resource values.
fw_activate: firmware activate.
The uAPI is backward compatible, if the reload action option is omitted
from the reload command, the driver reinit action will be used.
Note that when required to do firmware activation some drivers may need
to reload the driver. On the other hand some drivers may need to reset
the firmware to reinitialize the driver entities. Therefore, the devlink
reload command returns the actions which were actually performed.
By default reload actions are not limited and driver implementation may
include reset or downtime as needed to perform the actions.
However, if reload limit is selected, the driver should perform only if
it can do it while keeping the limit constraints.
Reload limit added:
no_reset: No reset allowed, no down time allowed, no link flap and no
configuration is lost.
Each driver which supports devlink reload command should expose the
reload actions and limits supported.
Add reload stats to hold the history per reload action per limit.
For example, the number of times fw_activate has been done on this
device since the driver module was added or if the firmware activation
was done with or without reset.
Patch 1 changes devlink_reload_supported() param type to enable using
it before allocating devlink.
Patch 2-3 add the new API reload action and reload limit options to
devlink reload.
Patch 4-5 add reload stats and remote reload stats. These stats are
exposed through devlink dev get.
Patches 6-11 add support on mlx5 for devlink reload action fw_activate
and handle the firmware reset events.
Patches 12-13 add devlink enable remote dev reset parameter and use it
in mlx5.
Patches 14-15 mlx5 add devlink reload limit no_reset support for
fw_activate reload action.
Patch 16 adds documentation file devlink-reload.rst

no_reset which does firmware live patching, updating the firmware image
without reset, no downtime and no configuration lose. The driver checks
if the firmware is capable of handling the pending firmware changes as a

Firmware live patch event notifies the driver that the firmware was just

re-initiate entities, part to updating the firmware version and
re-initiate the firmware tracer which can be updated by live patch with

Add support for devlink reload action fw_activate. To activate firmware
image the mlx5 driver resets the firmware and reloads it from flash. If
a new image was stored on flash it will be loaded. Once this reload
command is executed the driver initiates fw sync reset flow, where the
firmware synchronizes all PFs on coming reset and driver reload.

On sync_reset_now event the driver does reload and PCI link toggle to
activate firmware upgrade reset. When the firmware sends this event it
syncs the event on all PFs, so all PFs will do PCI link toggle at once.
To do PCI link toggle, the driver ensures that no other device ID under
the same bridge by checking that all the PF functions under the same PCI
bridge have same device ID. If no other device it uses PCI bridge link
control to turn link down and up.

Once the driver gets sync_reset_request from firmware it prepares for the
coming reset and sends acknowledge.
After getting this event the driver expects device reset, either it will
trigger PCI reset on sync_reset_now event or such PCI reset will be
triggered by another PF of the same device. So it moves to reset
requested mode and if it gets PCI reset triggered by the other PF it
detect the reset and reloads.

By default reload limit is unspecified and so no constraints on reload

Older ATF does not provide SMC call for SATA phy power on functionality and
therefore initialization of ahci_mvebu is failing when older version of ATF
is using. In this case phy_power_on() function returns -EOPNOTSUPP.
This patch adds a new hflag AHCI_HFLAG_IGN_NOTSUPP_POWER_ON which cause
that ahci_platform_enable_phys() would ignore -EOPNOTSUPP errors from
phy_power_on() call.
It fixes initialization of ahci_mvebu on Espressobin boards where is older
Marvell's Arm Trusted Firmware without SMC call for SATA phy power.
This is regression introduced in commit 8e18c8e58da64 ("arm64: dts: marvell:

defined and therefore ahci_platform_enable_phys() on Espressobin started

each topic is about a very specific *use* of sysfs, and sysfs *happens*
to be a (virtual) filesystem, so this is not really the right place.
It's jarring to be reading about filesystems in general and then come
across these specific details about PCI, and tagging...and then back to
general filesystems again.

kmalloc() of sufficiently big portion of memory is cache-aligned
in regular conditions. If some debugging options are used,
there is no reason qdisc structures would need 64-byte alignment
if most other kernel structures are not aligned.
This get rid of QDISC_ALIGN and QDISC_ALIGNTO.
Addition of privdata field will help implementing
the reverse of qdisc_priv() and documents where
the private data is.

This reverts commit 0a8159cbd11abf586693f1ec5264d0df587b71d8.
It turns out that this flag is used by iwldvm, so we can't get rid of
it. This broke iwldvm devices with BAD_COMMAND errors.

along with it.
