mlx5-updates-2022-08-22
Roi Dayan Says:
===============
Add support for SF tunnel offload
Mlx5 driver only supports VF tunnel offload.
To add support for SF tunnel offload the driver needs to:
1. Add send-to-vport metadata matching rules like done for VFs.
2. Set an indirect table for SF vport, same as VF vport.
info smaller sub functions for better maintainability.
rules from esw init phase to representor load phase.
SFs could be created after esw initialized and thus the send-to-vport
meta rules would not be created for those SFs.
By moving the creation of the rules to representor load phase
we ensure creating the rules also for SFs created later.

Lama Kayal Says:
================
Make flow steering API loosely coupled from mlx5e_priv, in a manner to
introduce more readable and maintainable modules.
Make TC's private, let mlx5e_flow_steering struct be dynamically allocated,
and introduce its API to maintain the code via setters and getters
instead of publicly exposing it.
Introduce flow steering debug macros to provide an elegant finish to the
decoupled flow steering API, where errors related to flow steering shall
be reported via them.
All flow steering related files will drop any coupling to mlx5e_priv,
instead they will get the relevant members as input. Among these,
fs_tt_redirect, fs_tc, and arfs.

Issue found during code review. This bug has no impact as long as the
ks8851_net structure is the first element of the ks8851_net_spi structure.
As long as the offset to the ks8851_net struct is zero, the container_of()
macro is subtracting 0 and therefore no damage done. But if the
ks8851_net_spi struct is ever modified such that the ks8851_net struct
within it is no longer the first element of the struct, then the bug would
manifest itself and cause problems.
struct ks8851_net is contained within ks8851_net_spi.
ks is contained within kss.
kss is the priv_data of the netdev structure.

In a large enough fleet of computers, it is common to have a few bad CPUs.
Those can often be identified by seeing that some commonly run kernel code,
which runs fine everywhere else, keeps crashing on the same CPU core on one
particular bad system.
However, the failure modes in CPUs that have gone bad over the years are
often oddly specific, and the only bad behavior seen might be segfaults
in programs like bash, python, or various system daemons that run fine
everywhere else.
Add a printk() to show_signal_msg() to print the CPU, core, and socket
at segfault time.
This is not perfect, since the task might get rescheduled on another
CPU between when the fault hit, and when the message is printed, but in
practice this has been good enough to help people identify several bad
CPU cores.
For example:
segfault[1349]: segfault at 0 ip 000000000040113a sp 00007ffc6d32e360 error 4 in \
segfault[401000+1000] likely on CPU 0 (core 0, socket 0)
This printk can be controlled through /proc/sys/debug/exception-trace.
[ bp: Massage a bit, add "likely" to the printed line to denote that
the CPU number is not always reliable. ]

* Use `ktime_get_real_ns()`

J7200: CPSW5G: Add support for QSGMII mode to am65-cpsw driver
Add support for QSGMII mode to am65-cpsw driver.
Change log:
v4-> v5:
1. Move ti,j7200-cpswxg-nuss compatible to the line above the
ti,j721e-cpsw-nuss compatible.
2. Add allOf and move if-then statements within it to allow future if-then
statements to be added easily.
v3 -> v4:
1. Update bindings to disallow ports based on compatible, instead of
adding a new if/then statement for the new compatible.
2. Add Else-If condition for RMII mode in the set of supported interfaces.
Support for RMII mode is already present in the driver and I had
missed out adding a condition for RMII mode in the previous patches.
v2 -> v3:
1. In ti,k3-am654-cpsw-nuss.yaml, restrict if/then statement to port
nodes.
v1 -> v2:
1. Add new compatible for CPSW5G in ti,k3-am654-cpsw-nuss.yaml and extend
properties for new compatible.
2. Add extra_modes member to struct am65_cpsw_pdata to be used for QSGMII
mode by new compatible.
3. Add check for phylink supported modes to ensure that only one phy mode
is advertised as supported.
4. Check if extra_modes supports QSGMII mode in am65_cpsw_nuss_mac_config()
for register write.
5. Add check for assigning port->sgmii_base only when extra_modes is valid.

In TI's J7200 SoC CPSW5G ports, each of the 4 ports can be configured
as a QSGMII main or QSGMII-SUB port. This configuration is performed
by phy-gmii-sel driver on invoking the phy_set_mode_ext() function.
It is necessary for the QSGMII main port to be configured before any of
the QSGMII-SUB interfaces are brought up. Currently, the QSGMII-SUB
interfaces come up before the QSGMII main port is configured.
Fix this by moving the call to phy_set_mode_ext() from
am65_cpsw_nuss_ndo_slave_open() to am65_cpsw_nuss_init_slave_ports(),
thereby ensuring that the QSGMII main port is configured before any of
the QSGMII-SUB ports are brought up.

Sometimes, gcc will optimize the function by spliting it to two or
more functions. In this case, kfree_skb_reason() is splited to
kfree_skb_reason and kfree_skb_reason.part.0. However, the
function/tracepoint trace_kfree_skb() in it needs the return address
of kfree_skb_reason().
This split makes the call chains becomes:
kfree_skb_reason() -> kfree_skb_reason.part.0 -> trace_kfree_skb()
which makes the return address that passed to trace_kfree_skb() be
kfree_skb().
Therefore, introduce '__fix_address', which is the combination of
'__noclone' and 'noinline', and apply it to kfree_skb_reason() to
prevent to from being splited or made inline.
(Is it better to simply apply '__noclone oninline' to kfree_skb_reason?
I'm thinking maybe other functions have the same problems)
Meanwhile, wrap 'skb_unref()' with 'unlikely()', as the compiler thinks
it is likely return true and splits kfree_skb_reason().

mock_gem_device() is the only one that modifies them. If that could be
fixed, we wouldn't have to do this.

Add initial runtime info that we can copy to runtime info at i915
creation time. This lets us define the initial values for runtime info
statically while making it possible to change them runtime. This will be
the new home for the current "const" device info members that are
modified runtime anyway.

variable 'mode' is used uninitialized whenever switch default is taken
in sps.c which leads to the following clang warning.
drivers/platform/x86/amd/pmf/sps.c:96:2: error: variable 'mode' is used uninitialized whenever switch default is taken [-Werror,-Wsometimes-uninitialized]
default:
^~~~~~~
drivers/platform/x86/amd/pmf/sps.c:101:9: note: uninitialized use occurs here
return mode;
^~~~
drivers/platform/x86/amd/pmf/sps.c:84:9: note: initialize the variable 'mode' to silence this warning
u8 mode;
^
= '\0'
1 error generated.
Fix it by returning -EOPNOTSUPP in default case and also change the return
type of the function amd_pmf_get_pprof_modes() to keep it similar like
other drivers which implement platform_profile.
