The --summary-mode option will select how to show the syscall summary at

the same as if --summary-mode=thread is passed.
The other option is to show total summary, which is --summary-mode=total.

It was using a RBtree-based int-list as a hash and a custom resort
logic for that. As we have hashmap, let's convert to it and add a
custom sort function for the hashmap entries using an array. It
should be faster and more light-weighted. It's also to prepare
supporting system-wide syscall stats.

After commit 5d4cc87414 ("net: reorganize "struct sock" fields"),
the sk_tsflags field shares the same cacheline with sk_forward_alloc.
The UDP protocol does not acquire the sock lock in the RX path;
forward allocations are protected via the receive queue spinlock;
additionally udp_recvmsg() calls sock_recv_cmsgs() unconditionally
touching sk_tsflags on each packet reception.
Due to the above, under high packet rate traffic, when the BH and the
user-space process run on different CPUs, UDP packet reception
experiences a cache miss while accessing sk_tsflags.
The receive path doesn't strictly need to access the problematic field;
change sock_set_timestamping() to maintain the relevant information
in a newly allocated sk_flags bit, so that sock_recv_cmsgs() can
take decisions accessing the latter field only.
With this patch applied, on an AMD epic server with i40e NICs, I
measured a 10% performance improvement for small packets UDP flood
performance tests - possibly a larger delta could be observed with more
recent H/W.

Martin hi,
The UFS4.1 standard, released on January 8, 2025, added a new exception
event: HEALTH_CRITICAL, which notifies the host of a device's critical
health condition. This notification implies that the device is approaching
the end of its lifetime based on the amount of performed program/erase
cycles.
Once an EOL (End-of-Life) exception event is received, we increment a
designated member, which is exposed via a sysfs entry. This new entry, will
report the number of times a critical health event has been reported by a
UFS device.
To handle this new sysfs entry, userspace applications can use select(),
poll(), or epoll() to monitor changes in the critical_health attribute. The
kernel will call sysfs_notify() to signal changes, allowing the userspace
application to detect and respond to these changes efficiently.
The host can gain further insight into the specific issue by reading one of
the following attributes: bPreEOLInfo, bDeviceLifeTimeEstA,
bDeviceLifeTimeEstB, bWriteBoosterBufferLifeTimeEst, and
bRPMBLifeTimeEst. All those are available for reading via the driver's
sysfs entries or through an applicable utility. It is up to userspace to
read these attributes if needed.

net: dsa: add support for phylink managed EEE
This series adds support for phylink managed EEE to DSA, and converts
mt753x to make use of this feature.
Patch 1 implements a helper to indicate whether the MAC LPI operations
are populated (suggested by Vladimir)
Patch 2 makes the necessary changes to the core code - we retain calling
set_mac_eee(), but this method now becomes a way to merely validate the
arguments when using phylink managed EEE rather than performing any
configuration.
Patch 3 converts the mt7530 driver to use phylink managed EEE.

Convert mt7530 to use phylink managed EEE. When enabling EEE, we set
both PMCR_FORCE_EEE1G and PMCR_FORCE_EEE100 irrespective of the speed,
and clear them both when disabling.

In order to allow DSA drivers to use phylink managed EEE, we need to
change the behaviour of the DSA's .set_eee() ethtool method.
Implementation of the DSA .set_mac_eee() method becomes optional with
phylink managed EEE as it is only used to validate the EEE parameters
supplied from userspace. The rest of the EEE state management should
be left to phylink.

Provide a helper to determine whether the MAC operations structure
implements the LPI operations, which will be used by both phylink and
DSA.

This commit introduces enhancements to the handling of the cleaner
shader fence in the AMDGPU MES driver:
- The MES (Microcode Execution Scheduler) now sends a PM4 packet to the
KIQ (Kernel Interface Queue) to request the cleaner shader, ensuring
that requests are handled in a controlled manner and avoiding the
race conditions.
- The CP (Compute Processor) firmware has been updated to use a private
bus for accessing specific registers, avoiding unnecessary operations
that could lead to issues in VF (Virtual Function) mode.
- The cleaner shader fence memory address is now set correctly in the
`mes_set_hw_res_pkt` structure, allowing for proper synchronization of
the cleaner shader execution.

Curret kfd does not allocate pasid values, instead uses pasid value for each
vm from graphic driver. So should not prevent graphic driver from releasing
pasid values since the values are allocated by graphic driver, not kfd driver
anymore. This patch does not stop graphic driver release pasid values.
Fixes: 8544374c0f ("drm/amdkfd: Have kfd driver use same PASID values from graphic driver")

MES fence_value will be updated in fence_addr if API success,
otherwise upper 32 bit will be used to indicate error code.
In any case, MES will trigger an EOP interrupt with 0xb1 as
context id in the interrupt cookie
