Date: Tue, 30 Jul 2024 04:49:18 +0000
Subject: perf/x86/rapl: Fix the energy-pkg event for AMD CPUs
commit 8d72eba1cf8cecd76a2b4c1dd7673c2dc775f514 upstream.
After commit:
63edbaa48a57 ("x86/cpu/topology: Add support for the AMD 0x80000026 leaf")
... on AMD processors that support extended CPUID leaf 0x80000026, the
topology_die_cpumask() and topology_logical_die_id() macros no longer
return the package cpumask and package ID, instead they return the CCD
(Core Complex Die) mask and ID respectively.
This leads to the energy-pkg event scope to be modified to CCD instead of package.
So, change the PMU scope for AMD and Hygon back to package.
On a 12 CCD 1 Package AMD Zen4 Genoa machine:
Before:
$ cat /sys/devices/power/cpumask
0,8,16,24,32,40,48,56,64,72,80,88.
The expected cpumask here is supposed to be just "0", as it is a package
scope event, only one CPU will be collecting the event for all the CPUs in
the package.
After:
$ cat /sys/devices/power/cpumask
0

Subject: [PATCH] net: remove NETIF_F_GSO_FRAGLIST from NETIF_F_GSO_SOFTWARE
Several drivers set NETIF_F_GSO_SOFTWARE, but mangle fraglist GRO packets
in a way that they can't be properly segmented anymore.
In order to properly deal with this, remove fraglist GSO from
NETIF_F_GSO_SOFTWARE and switch to NETIF_F_GSO_SOFTWARE_ALL (which includes
fraglist GSO) in places where it's safe to add.

Use the get_init_min_freq() callback to set the initial lower limit for
amd-pstate driver to lowest_nonlinear_freq instead of lowest_freq.
Modify the initial policy_data->min set by cpufreq-core to
lowest_nonlinear_freq, in the ->verify() callback. Also set the
cpudata->req[0] to FREQ_QOS_MIN_DEFAULT_VALUE (i.e. 0), so that it also

Subject: x86/amd: Rename amd_get_highest_perf() to
amd_get_boost_ratio_numerator()
The function name is ambiguous because it returns an intermediate value
for calculating maximum frequency rather than the CPPC 'Highest Perf'
register.
Rename the function to clarify its use and allow the function to return
errors. Adjust the consumer in acpi-cpufreq to catch errors.

Subject: x86/amd: Move amd_get_highest_perf() out of amd-pstate
amd_pstate_get_highest_perf() is a helper used to get the highest perf
value on AMD systems. It's used in amd-pstate as part of preferred
core handling, but applicable for acpi-cpufreq as well.
Move it out to cppc handling code as amd_get_highest_perf().

Subject: x86/amd: Detect preferred cores in amd_get_boost_ratio_numerator()
AMD systems that support preferred cores will use "166" as their
numerator for max frequency calculations instead of "255".
Add a function for detecting preferred cores by looking at the
highest perf value on all cores.
If preferred cores are enabled return 166 and if disabled the
value in the highest perf register. As the function will be called
multiple times, cache the values for the boost numerator and if
preferred cores will be enabled in global variables.

Subject: cpufreq: amd-pstate: Merge amd_pstate_highest_perf_set() into
amd_get_boost_ratio_numerator()
The special case in amd_pstate_highest_perf_set() is the value used
for calculating the boost numerator. Merge this into
amd_get_boost_ratio_numerator() and then use that to calculate boost
ratio.
This allows dropping more special casing of the highest perf value.

Subject: cpufreq: Add a callback to update the min_freq_req from drivers
Currently, there is no proper way to update the initial lower frequency
limit from cpufreq drivers. Only way is to add a new min_freq qos
request from the driver side, but it leads to the issue explained below.
The QoS infrastructure collates the constraints from multiple
subsystems and saves them in a plist. The "current value" is defined to
be the highest value in the plist for min_freq constraint.
The cpufreq core adds a qos_request for min_freq to be 0 and the amd-pstate
driver today adds qos request for min_freq to be lowest_freq, where
lowest_freq corresponds to CPPC.lowest_perf.
Eg: Suppose WLOG considering amd-pstate driver, lowest_freq is 400000 KHz,
lowest_non_linear_freq is 1200000 KHz.
At this point of time, the min_freq QoS plist looks like:
head--> 400000 KHz (registered by amd-pstate) --> 0 KHz (registered by
cpufreq core)
When a user updates /sys/devices/system/cpu/cpuX/cpufreq/scaling_min_freq,
it only results in updating the cpufreq-core's node in the plist, where
say 0 becomes the newly echoed value.
Now, if the user echoes a value 1000000 KHz, to scaling_min_freq, then the
new list would be
head--> 1000000 KHz (registered by cpufreq core) --> 400000 KHz (registered
by amd-pstate)
and the new "current value" of the min_freq QoS constraint will be 1000000
KHz, this is the scenario where it works as expected.
Suppose we change the amd-pstate driver code's min_freq qos constraint
to lowest_non_linear_freq instead of lowest_freq, then the user will
never be able to request a value below that, due to the following:
At boot time, the min_freq QoS plist would be
head--> 1200000 KHz (registered by amd-pstate) --> 0 KHz (registered by
cpufreq core)
When the user echoes a value of 1000000 KHz, to
/sys/devices/..../scaling_min_freq, then the new list would be
head--> 1200000 KHz (registered by amd-pstate) --> 1000000 KHz (registered
by cpufreq core)
with the new "current value" of the min_freq QoS remaining 1200000 KHz.
Since the current value has not changed, there won't be any notifications
sent to the subsystems which have added their QoS constraints. In
particular, the amd-pstate driver will not get the notification, and thus,
the user's request to lower the scaling_min_freq will be ineffective.
Hence, it is advisable to have a single source of truth for the min and
max freq QoS constraints between the cpufreq and the cpufreq drivers.
So add a new callback get_init_min_freq() add in struct cpufreq_driver,
which allows amd-pstate (or any other cpufreq driver) to override the
default min_freq value being set in the policy->min_freq_req. Now
scaling_min_freq can be modified by the user to any value (lower or
higher than the init value) later on if desired.
