Allow UBI devices to have a "volumes" firmware subnode with -volumes which may be compatible with "nvmem-cells". -Access to UBI volumes via the NVMEM interface at this point is -read-only, and it is slow, opening and closing the UBI volume for each -access due to limitations of the NVMEM provider API. - -Signed-off-by: Daniel Golle -Signed-off-by: Richard Weinberger ---- - drivers/mtd/ubi/Kconfig | 12 +++ - drivers/mtd/ubi/Makefile | 1 + - drivers/mtd/ubi/nvmem.c | 188 +++++++++++++++++++++++++++++++++++++++ - 3 files changed, 201 insertions(+) - create mode 100644 drivers/mtd/ubi/nvmem.c - ---- a/drivers/mtd/ubi/Kconfig -+++ b/drivers/mtd/ubi/Kconfig -@@ -104,4 +104,16 @@ config MTD_UBI_BLOCK - - If in doubt, say "N". - -+config MTD_UBI_NVMEM -+ tristate "UBI virtual NVMEM" -+ default n -+ depends on NVMEM -+ help -+ This option enabled an additional driver exposing UBI volumes as NVMEM -+ providers, intended for platforms where UBI is part of the firmware -+ specification and used to store also e.g. MAC addresses or board- -+ specific Wi-Fi calibration data. -+ -+ If in doubt, say "N". -+ - endif # MTD_UBI ---- a/drivers/mtd/ubi/Makefile -+++ b/drivers/mtd/ubi/Makefile -@@ -7,3 +7,4 @@ ubi-$(CONFIG_MTD_UBI_FASTMAP) += fastmap - ubi-$(CONFIG_MTD_UBI_BLOCK) += block.o - - obj-$(CONFIG_MTD_UBI_GLUEBI) += gluebi.o -+obj-$(CONFIG_MTD_UBI_NVMEM) += nvmem.o ---- /dev/null -+++ b/drivers/mtd/ubi/nvmem.c -@@ -0,0 +1,188 @@ -+// SPDX-License-Identifier: GPL-2.0-or-later -+/* -+ * Copyright (c) 2023 Daniel Golle -+ */ -+ -+/* UBI NVMEM provider */ -+#include "ubi.h" -+#include -+#include -+ -+/* List of all NVMEM devices */ -+static LIST_HEAD(nvmem_devices);

If RPS is enabled -then a flow for the skb is computed and based on the flow the skb can be -enqueued on a remote CPU. Scheduling/ raising the softirq (for backlog's -NAPI) on the remote CPU isn't trivial because the softirq is only -scheduled on the local CPU and performed after the hardirq is done. -In order to schedule a softirq on the remote CPU, an IPI is sent to the -remote CPU which schedules the backlog-NAPI on the then local CPU. - -On PREEMPT_RT interrupts are force-threaded. The soft interrupts are -raised within the interrupt thread and processed after the interrupt -handler completed still within the context of the interrupt thread. The -softirq is handled in the context where it originated. - -With force-threaded interrupts enabled, ksoftirqd is woken up if a -softirq is raised from hardirq context. This is the case if it is raised -from an IPI. Additionally there is a warning on PREEMPT_RT if the -softirq is raised from the idle thread. -This was done for two reasons: -- With threaded interrupts the processing should happen in thread - context (where it originated) and ksoftirqd is the only thread for - this context if raised from hardirq. Using the currently running task - instead would "punish" a random task. -- Once ksoftirqd is active it consumes all further softirqs until it - stops running. This changed recently and is no longer the case. - -Instead of keeping the backlog NAPI in ksoftirqd (in force-threaded/ -PREEMPT_RT setups) I am proposing NAPI-threads for backlog. -The "proper" setup with threaded-NAPI is not doable because the threads -are not pinned to an individual CPU and can be modified by the user. -Additionally a dummy network device would have to be assigned. Also -CPU-hotplug has to be considered if additional CPUs show up. -All this can be probably done/ solved but the smpboot-threads already -provide this infrastructure. - -Sending UDP packets over loopback expects that the packet is processed -within the call. Delaying it by handing it over to the thread hurts -performance. It is not beneficial to the outcome if the context switch -happens immediately after enqueue or after a while to process a few -packets in a batch. -There is no need to always use the thread if the backlog NAPI is -requested on the local CPU. This restores the loopback throuput. The -performance drops mostly to the same value after enabling RPS on the -loopback comparing the IPI and the tread result. - -Create NAPI-threads for backlog if request during boot. The thread runs -the inner loop from napi_threaded_poll(), the wait part is different. It -checks for NAPI_STATE_SCHED (the backlog NAPI can not be disabled). - -The NAPI threads for backlog are optional, it has to be enabled via the boot -argument "thread_backlog_napi".

It was verified that for correct function -of the LED if active high is needed, only BIT 6 is needed. - -Signed-off-by: Christian Marangi -Reviewed-by: Andrew Lunn -Link: https://lore.kernel.org/r/20240125203702.4552-6-ansuelsmth@gmail.com -Signed-off-by: Jakub Kicinski ---- - drivers/net/phy/at803x.c | 327 +++++++++++++++++++++++++++++++++++++++ - 1 file changed, 327 insertions(+) - ---- a/drivers/net/phy/at803x.c -+++ b/drivers/net/phy/at803x.c -@@ -301,6 +301,87 @@ - /* Added for reference of existence but should be handled by wait_for_completion already */ - #define QCA808X_CDT_STATUS_STAT_BUSY (BIT(1) | BIT(3)) - -+#define QCA808X_MMD7_LED_GLOBAL 0x8073 -+#define QCA808X_LED_BLINK_1 GENMASK(11, 6) -+#define QCA808X_LED_BLINK_2 GENMASK(5, 0) -+/* Values are the same for both BLINK_1 and BLINK_2 */ -+#define QCA808X_LED_BLINK_FREQ_MASK GENMASK(5, 3) -+#define QCA808X_LED_BLINK_FREQ_2HZ FIELD_PREP(QCA808X_LED_BLINK_FREQ_MASK, 0x0) -+#define QCA808X_LED_BLINK_FREQ_4HZ FIELD_PREP(QCA808X_LED_BLINK_FREQ_MASK, 0x1) -+#define QCA808X_LED_BLINK_FREQ_8HZ FIELD_PREP(QCA808X_LED_BLINK_FREQ_MASK, 0x2) -+#define QCA808X_LED_BLINK_FREQ_16HZ FIELD_PREP(QCA808X_LED_BLINK_FREQ_MASK, 0x3) -+#define QCA808X_LED_BLINK_FREQ_32HZ FIELD_PREP(QCA808X_LED_BLINK_FREQ_MASK, 0x4) -+#define QCA808X_LED_BLINK_FREQ_64HZ FIELD_PREP(QCA808X_LED_BLINK_FREQ_MASK, 0x5) -+#define QCA808X_LED_BLINK_FREQ_128HZ FIELD_PREP(QCA808X_LED_BLINK_FREQ_MASK, 0x6) -+#define QCA808X_LED_BLINK_FREQ_256HZ FIELD_PREP(QCA808X_LED_BLINK_FREQ_MASK, 0x7) -+#define QCA808X_LED_BLINK_DUTY_MASK GENMASK(2, 0) -+#define QCA808X_LED_BLINK_DUTY_50_50 FIELD_PREP(QCA808X_LED_BLINK_DUTY_MASK, 0x0) -+#define QCA808X_LED_BLINK_DUTY_75_25 FIELD_PREP(QCA808X_LED_BLINK_DUTY_MASK, 0x1) -+#define QCA808X_LED_BLINK_DUTY_25_75 FIELD_PREP(QCA808X_LED_BLINK_DUTY_MASK, 0x2) -+#define QCA808X_LED_BLINK_DUTY_33_67 FIELD_PREP(QCA808X_LED_BLINK_DUTY_MASK, 0x3) -+#define QCA808X_LED_BLINK_DUTY_67_33 FIELD_PREP(QCA808X_LED_BLINK_DUTY_MASK, 0x4) -+#define QCA808X_LED_BLINK_DUTY_17_83 FIELD_PREP(QCA808X_LED_BLINK_DUTY_MASK, 0x5) -+#define QCA808X_LED_BLINK_DUTY_83_17 FIELD_PREP(QCA808X_LED_BLINK_DUTY_MASK, 0x6) -+#define QCA808X_LED_BLINK_DUTY_8_92 FIELD_PREP(QCA808X_LED_BLINK_DUTY_MASK, 0x7) -+ -+#define QCA808X_MMD7_LED2_CTRL 0x8074 -+#define QCA808X_MMD7_LED2_FORCE_CTRL 0x8075 -+#define QCA808X_MMD7_LED1_CTRL 0x8076 -+#define QCA808X_MMD7_LED1_FORCE_CTRL 0x8077 -+#define QCA808X_MMD7_LED0_CTRL 0x8078 -+#define QCA808X_MMD7_LED_CTRL(x) (0x8078 - ((x) * 2)) -+ -+/* LED hw control pattern is the same for every LED */ -+#define QCA808X_LED_PATTERN_MASK GENMASK(15, 0) -+#define QCA808X_LED_SPEED2500_ON BIT(15) -+#define QCA808X_LED_SPEED2500_BLINK BIT(14) -+/* Follow blink trigger even if duplex or speed condition doesn't match */ -+#define QCA808X_LED_BLINK_CHECK_BYPASS BIT(13) -+#define QCA808X_LED_FULL_DUPLEX_ON BIT(12) -+#define QCA808X_LED_HALF_DUPLEX_ON BIT(11) -+#define QCA808X_LED_TX_BLINK BIT(10) -+#define QCA808X_LED_RX_BLINK BIT(9) -+#define QCA808X_LED_TX_ON_10MS BIT(8) -+#define QCA808X_LED_RX_ON_10MS BIT(7) -+#define QCA808X_LED_SPEED1000_ON BIT(6) -+#define QCA808X_LED_SPEED100_ON BIT(5) -+#define QCA808X_LED_SPEED10_ON BIT(4) -+#define QCA808X_LED_COLLISION_BLINK BIT(3) -+#define QCA808X_LED_SPEED1000_BLINK BIT(2) -+#define QCA808X_LED_SPEED100_BLINK BIT(1) -+#define QCA808X_LED_SPEED10_BLINK BIT(0) -+ -+#define QCA808X_MMD7_LED0_FORCE_CTRL 0x8079 -+#define QCA808X_MMD7_LED_FORCE_CTRL(x) (0x8079 - ((x) * 2)) -+ -+/* LED force ctrl is the same for every LED -+ * No documentation exist for this, not even internal one -+ * with NDA as QCOM gives only info about configuring -+ * hw control pattern rules and doesn't indicate any way -+ * to force the LED to specific mode. -+ * These define comes from reverse and testing and maybe -+ * lack of some info or some info are not entirely correct. -+ * For the basic LED control and hw control these finding -+ * are enough to support LED control in all the required APIs. -+ * -+ * On doing some comparison with implementation with qca807x, -+ * it was found that it's 1:1 equal to it and confirms all the -+ * reverse done.

Only after these steps, the -PHY will be attached. - -Signed-off-by: Arınç ÜNAL -Reviewed-by: Daniel Golle -Link: https://lore.kernel.org/r/20240430-b4-for-netnext-mt7530-use-switch-mdio-bus-for-phy-muxing-v2-1-9104d886d0db@arinc9.com -Signed-off-by: Paolo Abeni ---- - drivers/net/dsa/mt7530.c | 3 ++- - 1 file changed, 2 insertions(+), 1 deletion(-) - ---- a/drivers/net/dsa/mt7530.c -+++ b/drivers/net/dsa/mt7530.c -@@ -2484,7 +2484,8 @@ mt7530_setup(struct dsa_switch *ds) - if (!phy_node) - continue; - -- if (phy_node->parent == priv->dev->of_node->parent) { -+ if (phy_node->parent == priv->dev->of_node->parent || -+ phy_node->parent->parent == priv->dev->of_node) { - ret = of_get_phy_mode(mac_np, &interface); - if (ret && ret != -ENODEV) { - of_node_put(mac_np); diff --git a/target/linux/generic/backport-6.12/790-55-v6.11-net-dsa-mt7530-factor-out-bridge-join-leave-logic.patch b/target/linux/generic/backport-6.12/790-55-v6.11-net-dsa-mt7530-factor-out-bridge-join-leave-logic.patch deleted file mode 100644 index fdba021c17..0000000000 --- a/target/linux/generic/backport-6.12/790-55-v6.11-net-dsa-mt7530-factor-out-bridge-join-leave-logic.patch +++ /dev/null @@ -1,176 +0,0 @@ -From c25c961fc7f36682f0a530150f1b7453ebc344cd Mon Sep 17 00:00:00 2001 -From: Matthias Schiffer -Date: Tue, 18 Jun 2024 09:17:12 +0200 -Subject: [PATCH 1/2] net: dsa: mt7530: factor out bridge join/leave logic -MIME-Version: 1.0 -Content-Type: text/plain; charset=UTF-8 -Content-Transfer-Encoding: 8bit - -As preparation for implementing bridge port isolation, move the logic to -add and remove bits in the port matrix into a new helper -mt7530_update_port_member(), which is called from -mt7530_port_bridge_join() and mt7530_port_bridge_leave(). - -Another part of the preparation is using dsa_port_offloads_bridge_dev() -instead of dsa_port_offloads_bridge() to check for bridge membership, as -we don't have a struct dsa_bridge in mt7530_port_bridge_flags(). - -The port matrix setting is slightly streamlined, now always first setting -the mt7530_port's pm field and then writing the port matrix from that -field into the hardware register, instead of duplicating the bit -manipulation for both the struct field and the register. - -mt7530_port_bridge_join() was previously using |= to update the port -matrix with the port bitmap, which was unnecessary, as pm would only -have the CPU port set before joining a bridge; a simple assignment can -be used for both joining and leaving (and will also work when individual -bits are added/removed in port_bitmap with regard to the previous port -matrix, which is what happens with port isolation). - -No functional change intended. - -Signed-off-by: Matthias Schiffer -Reviewed-by: Wojciech Drewek -Reviewed-by: Arınç ÜNAL -Tested-by: Arınç ÜNAL -Signed-off-by: David S.

When the requirement for module support rose, the existing base -was improved to adopt modularization support, but kind of a design flaw -was introduced. With the existing implementation, when a storage device -registers into NVMEM, the core tries to hook a layout (if any) and -populates its cells immediately. This means, if the hardware description -expects a layout to be hooked up, but no driver was provided for that, -the storage medium will fail to probe and try later from -scratch. Even if we consider that the hardware description shall be -correct, we could still probe the storage device (especially if it -contains the rootfs). - -One way to overcome this situation is to consider the layouts as -devices, and leverage the native notifier mechanism. When a new NVMEM -device is registered, we can populate its nvmem-layout child, if any, -and wait for the matching to be done in order to get the cells (the -waiting can be easily done with the NVMEM notifiers). If the layout -driver is compiled as a module, it should automatically be loaded. This -way, there is no strong order to enforce, any NVMEM device creation -or NVMEM layout driver insertion will be observed as a new event which -may lead to the creation of additional cells, without disturbing the -probes with costly (and sometimes endless) deferrals. - -In order to achieve that goal we create a new bus for the nvmem-layouts -with minimal logic to match nvmem-layout devices with nvmem-layout -drivers.
