Geert Uytterhoeven <geert+renesas@glider.be> says:
Hi all,
Initialization of the UFS controller on R-Car S4-8 ES1.0 requires only
static values. However, other UFS controller variants (R-Car S4-8 ES 1.2)
require dynamic values, like those obtained from E-FUSE, and downloading
firmware.
Hence this patch series refactors the initialization code to prepare for
this, and adds support for the UFS controller on R-Car S4-8 ES1.2.
The accompanying DTS change is available at [1].
This has been tested on:
- Renesas Spider with R-Car S4-8 ES1.0 (broken before/after),
- Renesas S4 Starter Kit with R-Car S4-8 ES1.2 (works after).
Thanks for your comments!

A RISC-V platform can have both DMA coherent/noncoherent devices.
Since the RISC-V architecture is marked coherent, devices should
be marked as noncoherent when coherent devices exist.

be used on SG2044, and it has other coherent devices.

We do not and cannot support file locking with NFS reexport over
NFSv4.x for the same reason we don't do it for NFSv3: NFS reexport
server reboot cannot allow clients to recover locks because the source
NFS server has not rebooted, and so it is not in grace. Since the
source NFS server is not in grace, it cannot offer any guarantees that
the file won't have been changed between the locks getting lost and
any attempt to recover/reclaim them. The same applies to delegations
and any associated locks, so disallow them too.
Clients are no longer allowed to get file locks or delegations from a
reexport server, any attempts will fail with operation not supported.
Update the "Reboot recovery" section accordingly in
Documentation/filesystems/nfs/reexport.rst

The legacy rpc.nfsd tool will set the nlm_grace_period if the NFSv4
grace period is set. nfsdctl is missing this functionality, so add a new
netlink control interface for lockd that it can use. For now, it only
allows setting the grace period, and the tcp and udp listener ports.
lockd currently uses module parameters and sysctls for configuration, so
all of its settings are global. With this change, lockd now tracks these
values on a per-net-ns basis. It will only fall back to using the global
values if any of them are 0.
Finally, as a backward compatibility measure, if updating the nlm
settings in the init_net namespace, also update the legacy global
values to match.

specific and a task list for nova-core specifically.
The task list is divided into tasks for general Rust infrastructure
required by the project, tasks regarding GSP enablement and firmware
abstraction, general GPU driver tasks as well as tasks related to
external API design and test infrastructure.

There can be multiple cases of handling the GSP RPC messages, which are
the reply of GSP RPC commands according to the requirement of the
callers and the nature of the GSP RPC commands.
The current supported reply policies are "callers don't care" and "receive
the entire message" according to the requirement of the callers. To
introduce a new policy, factor out the current RPC command reply polices.
Also, centralize the handling of the reply in a single function.
Factor out NVKM_GSP_RPC_REPLY_NOWAIT as "callers don't care" and
NVKM_GSP_RPC_REPLY_RECV as "receive the entire message". Introduce a
kernel doc to document the policies. Factor out
r535_gsp_rpc_handle_reply().
No functional change is intended for small GSP RPC commands. For large GSP
commands, the caller decides the policy of how to handle the returned GSP
RPC message.

Device nodes in the examples are supposed to be enabled, so the schema
will be validated against them. Keeping them disabled hides potential
errors.

The example DTS uses 'num-ib-windows' and 'num-ob-windows' properties
but these are not defined in the binding. Binding also does not
reference snps,dw-pcie-common.yaml, probably because it is quite
different even though the device is based on Synopsys controller.
The properties are actually deprecated, so simply drop them from the
example.

The static function devm_pci_epc_match() is only invoked within the
devm_pci_epc_destroy(). However, since it was initially introduced,
this new API has had no callers.
Thus, remove both the unused API and the static function.

The function can be replaced by evict_inodes. The only difference is
that evict_inodes() skips the inodes with positive refcount without
touching ->i_lock, but they are equivalent as evict_inodes() repeats the
refcount check after having grabbed ->i_lock.

Specific constrain in if:then: blocks for variable lists, like clocks
and clock-names, should have a fixed upper and lower size. Older
dtschema implied minItems, but that's not true since 2024 and missing
minItems means that lower bound is not set.

Several devices have the same clock inputs, thus they can be in the same
if:then: clause, making everything smaller. No functional impact.
