From ed0f941022515ff40473ea5335769a5dc2524a3f Mon Sep 17 00:00:00 2001
From: Yuntao Liu <liuyuntao12@huawei.com>
Date: Mon, 3 Jun 2024 16:37:50 +0100
Subject: [PATCH] ARM: 9404/1: arm32: enable HAVE_LD_DEAD_CODE_DATA_ELIMINATION
The current arm32 architecture does not yet support the
HAVE_LD_DEAD_CODE_DATA_ELIMINATION feature. arm32 is widely used in
embedded scenarios, and enabling this feature would be beneficial for
reducing the size of the kernel image.
In order to make this work, we keep the necessary tables by annotating
them with KEEP, also it requires further changes to linker script to KEEP
some tables and wildcard compiler generated sections into the right place.
When using ld.lld for linking, KEEP is not recognized within the OVERLAY
command, and Ard proposed a concise method to solve this problem.
It boots normally with defconfig, vexpress_defconfig and tinyconfig.
The size comparison of zImage is as follows:
defconfig vexpress_defconfig tinyconfig
5137712 5138024 424192 no dce
5032560 4997824 298384 dce
2.0% 2.7% 29.7% shrink
When using smaller config file, there is a significant reduction in the
size of the zImage.
We also tested this patch on a commercially available single-board
computer, and the comparison is as follows:
a15eb_config
2161384 no dce
2092240 dce
3.2% shrink
The zImage size has been reduced by approximately 3.2%, which is 70KB on
2.1M.

Subject: [PATCH] mtd: spinand: set bitflip_threshold to 75% of ECC strength
Reporting an unclean read from SPI-NAND only when the maximum number
of correctable bitflip errors has been hit seems a bit late.
UBI LEB scrubbing, which depends on the lower MTD device reporting
correctable bitflips, then only kicks in when it's almost too late.
Set bitflip_threshold to 75% of the ECC strength, which is also the
default for raw NAND.

Preparation for adding TCP fraglist GRO support. It expects packets to be
combined in a similar way as UDP fraglist GSO packets.
For IPv4 packets, NAT is handled in the same way as UDP fraglist GSO.

This implements fraglist GRO similar to how it's handled in UDP, however
no functional changes are added yet. The next change adds a heuristic for
using fraglist GRO instead of regular GRO.

Subject: [PATCH 6/6] net: add heuristic for enabling TCP fraglist GRO
When forwarding TCP after GRO, software segmentation is very expensive,
especially when the checksum needs to be recalculated.
One case where that's currently unavoidable is when routing packets over
PPPoE. Performance improves significantly when using fraglist GRO
implemented in the same way as for UDP.
When NETIF_F_GRO_FRAGLIST is enabled, perform a lookup for an established
socket in the same netns as the receiving device. While this may not
cover all relevant use cases in multi-netns configurations, it should be
good enough for most configurations that need this.
Here's a measurement of running 2 TCP streams through a MediaTek MT7622
device (2-core Cortex-A53), which runs NAT with flow offload enabled from
one ethernet port to PPPoE on another ethernet port + cake qdisc set to
1Gbps.
rx-gro-list off: 630 Mbit/s, CPU 35% idle
rx-gro-list on: 770 Mbit/s, CPU 40% idle

Subject: [PATCH] phy: add driver for MediaTek XFI T-PHY
Add driver for MediaTek's XFI T-PHY which can be found in the MT7988
SoC. The XFI T-PHY is a 10 Gigabit/s Ethernet SerDes PHY with muxes on
the internal side to be used with either USXGMII PCS or LynxI PCS,
depending on the selected PHY interface mode.
The PHY can operates only in PHY_MODE_ETHERNET, the submode is one of
PHY_INTERFACE_MODE_* corresponding to the supported modes:
* USXGMII \
* 10GBase-R }- USXGMII PCS - XGDM \
* 5GBase-R / \
}- Ethernet MAC
* 2500Base-X \ /
* 1000Base-X }- LynxI PCS - GDM /
* Cisco SGMII (MAC side) /
I chose the name XFI T-PHY because names of functions dealing with the
phy in the vendor driver are prefixed "xfi_pextp_".
The register space used by the phy is called "pextp" in the vendor
sources, which could be read as "_P_CI _ex_press _T_-_P_hy", and that
is quite misleading as this phy isn't used for anything related to
PCIe, so I wanted to find a better name.
XFI is still somehow related (as in: you would find the relevant
places using grep in the vendor driver when looking for that) and the
term seemed to at least somehow be aligned with the function of that
phy: Dealing with (up to) 10 Gbit/s Ethernet serialized differential
signals.
In order to work-around a performance issue present on the first of
two XFI T-PHYs found in MT7988, special tuning is applied which can
be selected by adding the 'mediatek,usxgmii-performance-errata'
property to the device tree node, similar to how the vendor driver is
doing that too.
There is no documentation for most registers used for the
analog/tuning part, however, most of the registers have been partially
reverse-engineered from MediaTek's SDK implementation (see links, an
opaque sequence of 32-bit register writes) and descriptions for all
relevant digital registers and bits such as resets and muxes have been
supplied by MediaTek.

This copper module comes with broken TX_FAULT indicator which must be
ignored for it to work. Implement ignoring TX_FAULT state bit also
during reset/insertion and mute the warning telling the user that the
module indicates TX_FAULT.

Subject: [PATCH] ARM: 9404/1: arm32: fix boot hang with
HAVE_LD_DEAD_CODE_DATA_ELIMINATION
It was reported that some SoC (mvebu based for example) hang on kernel
loading. A variant of the feature was present in OpenWrt from long ago
and adding the additional entry with KEEP, fix the problem.
Fixes: ed0f94102251 ("ARM: 9404/1: arm32: enable HAVE_LD_DEAD_CODE_DATA_ELIMINATION")

Errors-To: linux-mtd-bounces+incoming=patchwork.ozlabs.org@lists.infradead.org
Reporting an unclean read from SPI-NAND only when the maximum number
of correctable bitflip errors has been hit seems a bit late.
UBI LEB scrubbing, which depends on the lower MTD device reporting
correctable bitflips, then only kicks in when it's almost too late.
Set bitflip_threshold to 75% of the ECC strength, which is also the
default for raw NAND.

Subject: [PATCH] net: add TCP fraglist GRO support
When forwarding TCP after GRO, software segmentation is very expensive,
especially when the checksum needs to be recalculated.
One case where that's currently unavoidable is when routing packets over
PPPoE. Performance improves significantly when using fraglist GRO
implemented in the same way as for UDP.
Here's a measurement of running 2 TCP streams through a MediaTek MT7622
device (2-core Cortex-A53), which runs NAT with flow offload enabled from
one ethernet port to PPPoE on another ethernet port + cake qdisc set to
1Gbps.
rx-gro-list off: 630 Mbit/s, CPU 35% idle
rx-gro-list on: 770 Mbit/s, CPU 40% idle

linux-firmware commit 808cba84 ("mtk_wed: add firmware for mt7988
Wireless Ethernet Dispatcher") added mt7988_wo_{0,1}.bin in the
'mediatek/mt7988' directory while driver current expects the files in
the 'mediatek' directory.
Change path in the driver header now that the firmware has been added.

List-Id: Linux Phy Mailing list <linux-phy.lists.infradead.org>
Add driver for MediaTek's XFI T-PHY, 10 Gigabit/s Ethernet SerDes PHY
which can be found in the MT7988 SoC.
The PHY can operates only in PHY_MODE_ETHERNET, the submode is one of
PHY_INTERFACE_MODE_* corresponding to the supported modes:
* USXGMII \
* 10GBase-R }- USXGMII PCS - XGDM \
* 5GBase-R / \
}- Ethernet MAC
* 2500Base-X \ /
* 1000Base-X }- LynxI PCS - GDM /
* Cisco SGMII (MAC side) /
In order to work-around a performance issue present on the first of
two XFI T-PHYs present in MT7988, special tuning is applied which can be
selected by adding the 'mediatek,usxgmii-performance-errata' property to
the device tree node.
There is no documentation for most registers used for the
analog/tuning part, however, most of the registers have been partially
reverse-engineered from MediaTek's SDK implementation (an opaque
sequence of 32-bit register writes) and descriptions for all relevant
digital registers and bits such as resets and muxes have been supplied
by MediaTek.
