Adds the prefix "_usart" in the name of stm32 usart functions in order to
ease the usage of kernel trace and tools, such as f-trace.
Allows to trace "stm32_usart_*" functions with f-trace. Without this patch,
all the driver functions needs to be added manually in f-trace filter.

Changes in v2:
- delete DMA cookie variables removal from V1 patch as already done by a
previous patch
- update commit message as DMA cookie variables removal is no more

Erwan Le Ray (8):
DMA initialization error handling is not properly implemented in the
driver.
Fix DMA initialization error handling by:
- moving TX DMA descriptor request error handling in a new dedicated
fallback_err label
- adding error handling to TX DMA descriptor submission
- adding error handling to RX DMA

SFP GPON module Ubiquiti U-Fiber Instant has in its EEPROM stored nonsense
information. It claims that support all transceiver types including 10G
Ethernet which is not truth. So clear all claimed modes and set only one
mode which module supports: 1000baseX_Full.
Also this module have set SFF
From: Russell King
Some GPON SFP modules (e.g. Ubiquiti U-Fiber Instant) have set both
SFP_OPTIONS_LOS_INVERTED and SFP_OPTIONS_LOS_NORMAL bits in their EEPROM.
Such combination of bits is meaningless so assume that LOS signal is not
implemented.
This patch fixes link carrier for GPON SFP
Workaround for GPON SFP modules based on VSOL V2801F brand was added in
commit 0d035bed2a4a ("net: sfp: VSOL V2801F / CarlitoxxPro CPGOS03-0490
v2.0 workaround"). But it works only for ids explicitly added to the list.
As there are more rebraded VSOL V2801F modules and OEM vendors are putting

This is second patch series which adds workaround for broken GPON SFP

Hi,

and someone tried to use it with hardened memory allocator library.
Execution time was increased to extreme (minutes) and as we found, the problem

Another factoid to add to this: I captured all traffic on an
interface while the test program was running using
tcpdump -i wlo1 -w capture.pcap
observing that multiple packets got through the filter. I then built
the bpf_dbg program from the kernel source tree and ran the same
filter and

Same as your previous patch, the description does not match the change.

Hi Suzuki,
In addition to altering patch 18, to put the newly accessible
TRCDEVARCH register into the more appropriate 'mgmt' subdir for
CoreSight management registers, an update is needed to
./Documentation/ABI/testing/sysfs-bus-coresight-devices-etm4x to add a
reference for this new sysfs file

We call do_machine_check() from a 'safe' context, instrumentation
should be possible. However, due to the nature of the beast, MCE is
fragile and we really rather would not want to hit additional code.
Currently this is done by marking do_machine_check() as noinstr,
however there's at least one

With exception of patch #6 (which I'm really not sure about), this series cures
all noinstr warnings I found today after looking at a report from Randy.
Please consider...
There's some explicit tracing left in exc_machine_check_kernel(),
remove it, as it's already implied by irqentry_nmi_enter().

Use existing rx processed count to track against budget, thereby making
budget decrement operation redundant.
rx_desc_count can be calculated outside the rx loop, making the loop a
bit smaller.

Hi Masahiro,
With v5.11-rc1 and commit("1e860048c53ee gcc-plugins: simplify GCC

We can increase the efficiency of rx path by using buffers to receive
packets then build SKBs around them just before passing into the network
stack. In contrast, preallocating SKBs too early reduces CPU cache
efficiency.
Check if we're in NAPI context when refilling RX. Normally we're almost
The rx SKB ring use the same code for cleanup at various points.
Combine them into a function to reduce lines of code.

Use netdev_alloc_skb_ip_align on newer SoCs with integrated switch
(enetsw) when refilling RX. Increases packet processing performance
by 30% (with netif_receive_skb_list).
Non-enetsw SoCs cannot function with the extra pad so continue to use
the regular netdev_alloc_skb.
Tested on BCM6328 320

This patch series aim to improve the bcm63xx_enet driver by integrating the
latest networking features, i.e. batched rx processing, BQL, build_skb,

The newer enetsw SoCs are found to be able to do unaligned rx DMA by adding
